Description

[Detailed Description of the Invention] The present invention relates to a transmission operating device that mechanically operates the shift lever of a column shift type transmission, and is particularly useful for bench testing and simulation of automobiles.

For bench testing of automobiles, a transmission operating device that can mechanically operate a transmission shift lever is required for programming and remote control of the transmission. Figures 1-3 show prior art devices of this type. In the figure, 1 is a shift lever, 2 is a spring rod that engages the upper end of the shift lever 1 with a ball joint 2' at its tip, and 3 and 4 are actuators for shift operation arranged approximately at right angles to each other, and a selector lever. This is an actuator for operation.

The output shaft 5 of the shift operation actuator 3 has a universal joint 6 in the middle, and a swing arm 8 whose tip is engaged with the spring rod 2 by a uniball 7.
The base of the shaft is attached to the shaft. On the other hand, the output shaft 9 of the select operation actuator 4 has a universal joint 10 at its tip.
A swing arm 11 connected to the base end of the spring rod 2 is pivotally attached. In addition, 12 and 13 are an oil supply pipe and an oil drain pipe that respectively supply and discharge oil to the actuator, 14 is a servo valve, and 1
5 is a short circuit solenoid valve.

Therefore, according to the above configuration, by operating the shift operation actuator 3, the tip end side of the spring rod 2 can be swung in the longitudinal direction in FIG. 1, thereby causing the shift lever 1 to perform a shift operation. In addition, actuator 4 for select operation
When actuated, the spring rod 2 is moved in the axial direction, allowing the shift lever 1 to perform a selection operation.

However, according to the conventional transmission operation device, the two actuators 3 and 4 for shift operation and selection operation are installed independently from each other on a plane, so the installation area becomes large and the arrangement position is limited. It's also difficult to adjust. Furthermore, since it is a large-scale device, the car seat must be removed to install it, which is not only cumbersome, but also especially in passenger cars and small trucks with a bench seat that integrates the passenger and driver seats, making it impossible to remove the seat and make it impossible to install it. It was possible.
Also, the interior of the car was often dirty due to oil leaks.

In view of the problems of the prior art described above, the present invention aims to provide a column shift type transmission operating device that has a simple and lightweight structure, is easy to adjust, and has good attachment/detachability.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 shows an embodiment of the device mounted on the steering wheel 18 of a column shift type automobile;

A mounting plate with attached bone plate 22a, 24 is a support cylinder which is erected on the mounting plate 22 and has bearings 25, 25a fitted on its outer periphery to form a bearing part, 26 is a key for locking the bearing 25a, and 27 is a support cylinder. An inner cylinder having splines on the outer periphery (hereinafter referred to as "spline inner cylinder") supported by the support cylinder 24 via bearings 25, 25a, 28 denotes the spline inner cylinder 2.
An outer cylinder (hereinafter referred to as an "operating cylinder") having a spline part 28a that fits into the operating cylinder 7, and an outer cylinder 29 attached to the non-fitting end of the operating cylinder 28 via a ring plate 30 and connecting the outer cable 16b of the select cable 16. As shown in detail in FIG. 8, a connector 31 is attached to the mounting plate 22 via a mounting member 32, and faces the inner lower part of the support tube 24 from the hole 22b of the mounting plate 22, as shown in detail in FIG. 16 inner cable 1
6a is connected at one end, 33 is a fixture for securing the outer cable 16b of the select cable 16 at the other end, and 34 is a selector for connecting the inner cable 16a of the select cable 16 at the other end. Actuator, 35 is shift cable 2
0 is a fixture for fixing the outer cable 20b at the other end; 36 is a shift actuator to which the inner cable 20a of the shift cable 20 is connected at the other end; 37 is a shift actuator whose base end 37a is attached to the outer circumference of the spline inner cylinder 27; A shift arm is fixed to a plurality of spline teeth 27a, and 38 is a link ball that connects the tip of the shift arm 37 and one end of the inner cable 20a of the shift cable 20.
Reference numerals 39 and 40 denote female coupler bodies provided at the ends of the mounting plate 22, and 39a a male coupler body which is fitted onto the shift cable 20 and rotatably fitted into the female coupler body 39 or 40 as a pair. , 41 is a first operating arm with a bone plate 41a protruding from the outer periphery of the operating cylinder 28, and 42 is two link balls 43, 43.
The second operating arm is connected to the first operating arm 41 at the proximal end via a, and forms an operating arm together with the first operating arm 41, and has a connector 44 for connecting to the shift lever 17 at its tip; 45 is a shift lever; 17 and a transmission (not shown). Note that 19 is a steering column, and 21 is a steering shaft.

The locking tool 31 is a coupler that can be attached and detached with a single touch together with the connecting tool 29, and as shown in FIGS. 6 and 8, respectively, cylinder bodies (sleeves) 29b and 31b are biased in the axial direction and loosely fit around the outer periphery. The engagement between the tubular outer body (coupler female body) 29c, 31c and the coupler female body 29c, 31c is the sleeve 29b, 3
It consists of tubular inner bodies (coupler male bodies) 29a and 31a which are released by movement of 1b in the opposite biasing direction. In addition, 29
d and 31d are coil springs, and 29e and 31e are balls. Therefore, one end of the select cable 16 is inserted into the operation tube 28 through the coupler male body 29a of the connector 29, and the outer cable 16
b is fixed to the coupler male body 29a and the operating cylinder 28
axially integrally and removably connected to. On the other hand, one end of the inner cable 16a inside the operation tube 28 is fixed to the coupler male body 31a of the locking tool 31 at the lower part of the support tube 24. In this case, since the connector 29 is exposed, the outer cable 16b and the operation tube 28 are connected to each other by the sleeve 29b.
It can be attached and detached with one-touch operation. On the other hand, it is difficult to connect and disconnect the inner cable 16a and the mounting plate 22 with a single touch because the locking tool 31 is located deep inside the support tube 24. This must be done after removing it from the plate 22. In this invention, the support tube 2
4 has a metal or non-metal attachment/detachment cylinder 46 inside.
By loosely fitting the inner cable 16a, it is possible to attach and detach the inner cable 16a with the fastener 31 attached. That is, when the operation cylinder 28 is pushed down sufficiently beyond the normal stroke, the ring plate 30 presses down the attachment/detachment cylinder 46 as shown by the two-dot chain line in FIG. The male coupler body 31a and the female coupler body 31 are moved in the opposite biasing direction.
c can be attached and detached. Note that when the detachable cylinder 46 is in a free state, the urging force of the coil spring 31d overcomes the force and pushes the detachable cylinder 46 upward.

Furthermore, the shift lever connector 44 at the tip of the second operation arm 42 allows the shift lever 17 to be inserted and held even with the shift knob 17a attached.
As shown in FIG. 9, which is a partially cutaway view of the main part of FIG.

It has an outer diameter that matches the inner diameter of the spherical bearing 49, has a step 50a on one end that abuts against the side surface of the spherical bearing 49, has a tapped hole for a set bolt 51 on the other end, and has a stepped hole 50a for a set bolt 51 on the other end. The inner ring 49b of the spherical bearing 49 has a central valley-shaped notch 50b in which the plate 52 is accommodated, and tap holes provided in the notch 50b for the four bolts 53 that fix the lever holding plate 52.
A lever holding member 5 having a substantially V-shaped cross section is fitted inside.
It becomes 0. Note that 49a is the outer ring of the spherical bearing 49.

In the device of this embodiment having the above structure, the mounting plate 2
2. The support member consisting of the support cylinder 24 and bearings 25 and 25a pivotally supports the spline inner cylinder 27 so that the spline inner cylinder 27 becomes coaxial with the rotation center of the shift lever 17 in the shift direction, that is, the axis of the shift rod 45. It is fixedly mounted on the steering wheel 18 with a U-bolt 23. The shift cable 20 is
In this case, with the male coupler 39a inserted into the female coupler 39, one end of the inner cable 20a and the shift arm 37 of the spline inner cylinder 27 are connected by bolting the link ball 38.
The operation tube 28 has coupler male bodies 29a, 31a and coupler female bodies 29c,
31c, the first and second
The operating arm consisting of the operating arms 41 and 42 is fitted into the spline inner cylinder 27 with its position matched to the position of the shift lever 17 (for example, neutral). Inner cable 16 of select cable 16
The coupler male body 31a at the tip a is held in place by holding the operation tube 28 and pushing down the attachment/detachment tube 46.
1c. Also, the coupler male body 29a at the tip of the outer cable 16b of the select cable 16
is engaged with the female coupler body 29c by simply pushing down the sleeve 29b by hand. Next, the connector 44 of the second operating arm 42 is attached to the lever presser plate 52 and the lever presser member 50, which have been removed from the spherical bearing 49 in advance, by first clamping the lever presser plate 52 and the lever presser member 50 to the shift lever 17 with the bolts 53. is inserted and fixed into the spherical bearing 49 and attached to the shift lever 17.

The apparatus of this embodiment having such a configuration operates as follows. Now, assume that the shift lever 17 is in the neutral position as shown by the solid line in FIGS. 5 and 7. At this time, the selection actuator 34
Assume that the other end side of the inner cable 16a of the select cable 16 is moved back and forth in the direction of arrow F by operating the select cable 16 appropriately. In the select cable 16, the inner cable 16a is restricted from moving in the axial direction by the fastener 31 at one end, and the outer cable 16b is fixed by the fastener 33 at the other end, so that the fastener 31 and the fastener 33, the route of the select cable 16 changes, and the connecting tool 3 changes accordingly.
As a result of the expansion and contraction between the connecting member 29 at the tip of the outer cable 16b and the free end of the outer cable 16b, the operation cylinder 28 moves up and down as shown by arrow D, and the shift lever 17 is moved in the selection direction A. On the other hand, assume that the shift actuator 36 is operated to move the other end of the inner cable 20a of the shift cable 20 back and forth in the direction of arrow G. Since the outer cable 20b of the shift cable 20 is only fixed at both ends, one end, which is the free end of the inner cable 20a, moves in conjunction with the other end, thereby causing the spline inner cylinder 27 to move along with the shift arm 37 in the direction of the arrow. As a result of rotating in the J direction, the operation tube 28 moves into the first and second operation arms 41 and 42.
At the same time, the shift lever 17 rotates in the direction of the arrow E, and the shift lever 17 rotates in the shift direction B. In this case, the support tube 24
is arranged on the rotation center of the shift lever 17, so that the rotation center of the spline inner cylinder 27 and the operation cylinder 28, and in turn, the rotation center of the first and second operation arms 41, 42, and the rotation center of the shift lever 17. The center of rotation in the shift direction coincides, and the operating force of the operating arm is smoothly transmitted to the shift lever 17 without loss. Further, one end of the shift cable 20 is rotatably supported by the female coupler 39 and the male coupler 39a, and the inner cable 20a is connected to the shift arm 37 via the link ball 38, so that the inner cable 20a is The longitudinal movement is smoothly converted into rotation of the shift arm 37. Furthermore, since the operating force is transmitted from the second operating arm 42 to the shift lever 17 via the spherical bearing 49, it is smooth in both the select direction A and the shift direction B. Furthermore, the coupler male bodies 29a, 31 are connected to the coupler female bodies 29c, 31c in both the connector 29 and the fastener 31.
Since a is rotatable, the select cable 16 is not twisted even if the operation tube 28 is rotated.

FIG. 10 shows another implementation mode of the device of this embodiment.

The present invention has been explained in detail with reference to the embodiments above, and the column shift type transmission operating device according to the present invention has a mounting plate attached to a steering wheel; a bearing on the outer periphery; an inner cylinder having a spline on its outer periphery (spline inner cylinder) which is rotatably supported on the outer periphery of the support cylinder via the bearing; a mounting device for mounting the mounting plate on the steering wheel at a position where the axis of the inner cylinder coincides with the center of rotation in the shift direction of the shift lever; a shift arm that rotates integrally with the shift arm; a shift cable that has an outer cable and an inner cable; a shift actuator that is connected to the shift arm by the shift cable and rotates the shift arm; a select cable having a cable, one end of which is inserted into the outer cylinder; a connector that integrally connects an outer cable at one end of the select cable to the outer cylinder in the axial direction;
A tubular outer body mounted on the mounting plate facing into the support cylinder, a tubular inner body fixed to an inner cable on one end side of the select cable and removably coupled to the tubular outer body, and a tubular outer body. a locking device consisting of a cylinder that is biased in the axial direction on the outer periphery, is loosely fitted, and is moved in the opposite biasing direction to allow the tubular outer body and the tubular inner body to be attached and detached; a protrusion provided; a protrusion that is loosely fitted on the inner periphery of the support cylinder, and is abutted against the protrusion by the axial movement of the outer cylinder to push the cylindrical body of the locking device in the counter-biasing direction; a cylindrical body; a fixing device for fixing the position of an outer cable at the other end of the select cable; a select actuator connected to the inner cable at the other end of the select cable to move the outer cable in the axial direction; an operating arm that projects from the outer cylinder and is connected to the shift lever via a shift lever connector. Therefore, the shift link mechanism and the select link mechanism have a cylindrical structure, making it simple, compact, and lightweight with fewer parts.Moreover, both mechanisms are coaxially combined, making it even simpler, lighter, and reducing costs. I was able to figure it out. Further, since both mechanisms are removably engaged with splines, the installation work is easy, and the operation arm and shift lever can be easily aligned by relative alignment between the inner cylinder and the outer cylinder. Further, since the relationship between the inner cylinder and the outer cylinder is relative, the direction in which the shift cable connecting the inner cylinder and the shift actuator is drawn out can be freely selected 360 degrees. Furthermore, since the rotation center of the operating arm coincides with the rotation center of the shift lever, the shift lever can be operated smoothly.

More importantly, the locking device that locks the inner cable of the select cable is a one-touch type, and the detachable cylinder that can come into contact with this sleeve is loosely fitted into the inner periphery of the support cylinder. Even though the anchor is located deep within the support tube, the inner cable can be attached and detached by simply moving the outer tube. As a result, even if the space for mounting the device of the present invention is small, it is very easy to install and remove the device.
In addition, there is no need for a peephole, operation hole, or special tools, and since it is no longer necessary to remove the fasteners from the mounting plate each time, there is no need to spend time attaching or detaching them, and there is no loss, wear, or damage to parts.

As specifically explained above, the present invention is particularly useful for mechanical operation of a transmission in bench tests and simulations of automobiles. Furthermore,
Since the select cable can be attached and detached by remote control, it is small, lightweight, and easy to install and adjust, making it extremely easy to implement in narrow spaces such as the driver's seat in a car. In addition, the device of the present invention
For column shift type vehicles, it can be installed on the steering wheel, so it can be used in all types of vehicles regardless of the seat type, such as bench seats or separate seats.
