Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field The present invention is an automatic transmission operation device mainly arranged on the side of the driver's seat of an automobile, particularly a mounting plate.
A shift lever pivotally supported by the mounting plate so as to be rotatable between a plurality of shift positions; a control rod disposed within the shift lever so as to be movable up and down; and a control rod disposed along the direction of rotation of the shift lever. The control rod is provided with an engagement pin that engages with the lockout plate to regulate the shift position of the shift lever, and the shift lever includes a lockout plate and a detent plate that are mounted on the mounting plate. The present invention relates to an operating device for an automatic transmission, which is provided with an engager that engages with a detent plate and gives the lever a degree of rotation corresponding to a shift position.

(2) Prior Art In such a conventional operating device, a lockout plate and a detent plate are formed integrally with each other (see, for example, Japanese Utility Model Publication No. 59-33703).

(3) Problems to be solved by the invention In the conventional structure, when the shift lever is regulated to a predetermined shift position by the lockout plate, the daytent plate must be properly adjusted to give rotation moderation to the shift lever. In order to operate, both plates and related parts must be manufactured with high precision, which reduces manufacturing efficiency and increases the cost of the device.

The present invention was developed in view of these circumstances, and it is a simple and easy-to-use design that allows for a large amount of manufacturing error in each part, and also allows for reliable synchronization of the lockout plate and detent plate operating timing. It is an object of the present invention to provide an effective operating device.

B. Structure of the invention (1) Means for solving the problem In order to achieve the above object, the present invention provides a method for mutually adjusting the positions of the lockout plate and the detent plate around the pivot axis of the shift lever. The present invention is characterized in that an adjustment mechanism is interposed between at least one of the plates and the mounting plate.

(2) Effects According to the above configuration, by adjusting the positions of the lockout plate and the detent plate, manufacturing errors in each part can be compensated for, and the operating timings of the gallery plates can be reliably synchronized.

(3) Embodiment An embodiment of the present invention will be explained below with reference to the drawings. First, in Fig. 1, the shift lever 1 is
is rotatably supported by a pivot 3 on a mounting plate 2 fixed to a floor plate (not shown) of the vehicle body in the longitudinal direction of the vehicle body. A manual valve (not shown) of the automatic transmission is controlled.

The shift lever 1 includes a lever lower part 1a having a U-shaped cross section and a boss 5 at the lower end, and a lever lower part 1a having a U-shaped cross section.
It consists of a pipe-shaped lever upper part 1b that fits into the upper end of the lever part 1b and is connected to the upper end of the lever part 1b, and a lever knob 1c that fits into the upper part of the lever part 1b and is fixed with a screw 6. 3 via a bush 7, and a terminal rod 4a of an operating wire 4 connected to a manual valve of an automatic transmission is connected to the lower part 1a of the lever (see FIG. 2). The terminal rod 4a is provided with a turnbuckle 8 for length adjustment.

The lever knob 1c is provided with a vertical hole 9 that communicates with the hollow part of the lever upper part 1b, and a horizontal hole 10 that is perpendicular to the vertical hole 9 in a T-shape, and one end of the horizontal hole 10 faces toward the driver's seat. It was once open, and the other end is a dead end.

A push button 11 is slid into the horizontal hole 10,
As a result, a control rod 12 that can be raised and lowered is disposed across the vertical hole 9 and the hollow part of the lever upper part 1b.

The upper end of the control rod 12 projects into a transverse hole 10, into which a pressure roller 13 is pivoted 14. This pressing roller 13 is engaged with a slope 11a formed at the inner end of the push button 11 so that it is pushed toward the control rod 12 by the pushing operation of the push button 11.

In order to prevent incorrect assembly of the push button 11 to the pressure roller 13, a key 15 is provided protruding from the lower surface of the push button 11, and a key groove 16 that engages with the key 15 is recessed in the bottom wall of the horizontal hole 10. Ru. In order to prevent the push button 11 from slipping out of the horizontal hole 10, a long hole 17 is formed in the push button 11 in the axial direction thereof, and a stopper pin 18 to be inserted into the long hole 17 is fixed to the lever knob 1c. be done.

The control rod 12 includes an upper rod 19 that supports the pressure roller 13 and a hollow lower rod 20 located below the upper rod 19.
The small diameter portion 19a formed at the lower end of the lower rod 2
It is slid into the hollow part of 0.

A pin 21 is fixed to the lower end of the small diameter portion 19a, passing through it laterally, and both ends of the pin 21 are slidably fitted into long holes 22 formed in the lower rod 20 in the axial direction. will be combined. This allows the rods 19, 20 to move relative to each other within a certain range while preventing relative rotation.

The upper and lower rods 19, 20 are connected to the horizontal hole 10.
and is biased in the upward direction by upper and lower return springs 23 and 24 housed in the lever upper part 1b, respectively.

An engagement pin 25 is fixed to the lower end of the lower rod 20, passing through it in the left-right direction. Engagement pin 2
5 has a pair of left and right metal guide rollers 26 with the lower rod 20 in between, and a synthetic resin rock roller 2 adjacent to the left guide roller 26.
7 are rotatably fitted respectively. In order to prevent these rollers 26, 26, and 27 from coming off, a bulge 25a is formed at one end of the engagement pin 25, and a clip 28 is secured to the other end.

The pair of guide rollers 26, 26 are slidably fitted into elongated holes 29, 29, which are formed long in the axial direction in the left and right side walls of the lever lower part 1a, respectively. This allows the lower rod 20 to move up and down while preventing it from rotating.

The lock roller 27 cooperates with a lockout plate 30 disposed on the left side of the shift lever 1 to regulate the shift position of the shift lever 1.

As shown in FIG. 2, the lockout plate 30 is disposed along the rotating direction of the shift lever 1 and is attached to the mounting plate by a pair of front and rear bolts 31, 31.
is fixed to. A regulation hole 32 is bored in the plate 30, and the rock roller 27 engages with a cam surface 32a on the ceiling of the regulation hole 32.

In the illustrated example, the shift lever 1 has six shift positions from the front to the rear of the vehicle: parking range P, reverse range R, neutral range N, overdrive range OD, normal drive range D, and low speed hold range L. The cam surface 32a is formed in correspondence with these shift positions.

That is, the cam surface 32a is formed high in the N to D range portions and low in the R and L range portions. Further, the P range part is formed at the same height as the R range part, but a downward protrusion is provided between them. Incidentally, the portion of the cam surface 32a that has no undulations is an arcuate surface centered on the pivot shaft 3.

Therefore, the shift lever 1 can be rotated between N and D ranges without lowering the rotary roller 27, but the shift lever 1 cannot be rotated from N to R range or from D to L range. This can only be done by lowering the rock crawler 27. Further, the shift lever 1 cannot be rotated between the R and P ranges without always lowering the rocker roller, regardless of the direction of rotation.

To lower the rock roller 27, the push button 11 can be pressed. When the push button 11 is pressed, its slope 11a pushes down the upper rod 19 of the control rod 12 through the pressure roller 13 against the force of the upper return spring 23, and then the upper rod 1
9 pushes down the lower rod 20 through the pin 21 against the force of the lower return spring 24, so that the engagement pin 2
5, the rock roller 27 is lowered.

By the way, the control rod 12 is divided into an upper rod 19 and a lower rod 20, and an upper return spring 23
Since the upper rod 19 is individually biased in the upward direction by the lower return spring 24 and the lower return spring 24, the upper rod 19
Regardless of the vertical position of the lower rod 20, the pressing roller 13 can always be brought into pressure contact with the slope 11a of the push button 11, and therefore the push button 11 can be prevented from moving inadvertently. On the other hand, at any shift position of the shift lever 1, the lower rod 20 presses the rod roller 27 against a predetermined location of the cam surface 32a of the regulation hole 32 by the force of the lower return spring 24, and the roller 27 and the lower rod 2
0 vibration can be suppressed.

If the lock roller 27 is biased in the direction in which it comes into pressure contact with the cam surface 32a of the regulation hole 32, for example, when the shift lever 1 is rotated from the R range to the N range (in this case, the push button 1
1 does not need to be pressed), the rod roller 27 rises rapidly, and the force of the lower return spring 24 and the lower rod 2
Due to the inertia of zero, the N range part of the cam surface 32a will be hit hard, but this
As mentioned above, it is made of synthetic resin and has appropriate elasticity, so it can absorb the impact by itself.

This phenomenon also occurs when the push button 11 is rapidly released from the depressed position.

Also, shift the shift lever 1 from the N range to the D range, for example.
When rotating to the range, the rock roller 27 rolls on the cam surface 32a, so the frictional resistance with the cam surface 32a is extremely small.

In FIGS. 1 and 3, the daytent device 33 is used to rotate the shift lever 1 to each shift position.
gives moderation. The detent plate 34 of the detent device 33 is arranged parallel to the lockout plate 30 with the shift lever 1 in between, and is connected to two sets of bolts and nuts 36, 3.
7, 36, and 37, and the bracket 35 is fixed to the mounting plate 2 by bolts 38.
is fixed to.

The entire detent plate 34 has an arc shape centered on the pivot shaft 3 of the shift lever 1, and a plurality of notches 39, 39, . . . corresponding to each shift position of the shift lever 1 are provided on the lower surface thereof. Engagement element 4 selectively engages with these notches 39, 39...
0 is a spring 42 that springs the locking element 40 toward the notches 39, 39, .
It is stored with.

Then, when the operator turns the shift lever 1 to a shift position somewhere between the P and L ranges,
The engaging element 40 engages with the notch 39 corresponding to that position with the elastic force of the spring 42, giving the operator a sense of control over the rotational operation and holding the shift lever 1 at the shift position.

Attachment holes 4 are formed at both ends of the detent plate 34 for the insertion of the bolts 36, 36.
3 and 43 are formed into arcuate long holes centered on the pivot shaft 3. Therefore, when assembling,
By adjusting the position of the detent plate 34 along the mounting holes 43, 43, the engager 40 can be accurately engaged with the corresponding notch 39 at a predetermined shift position of the shift lever 1. After this adjustment, the bolts and nuts 36, 37, 36, 37 are tightened. Therefore, the bolt 36 and nut 37
The mounting holes 43 and 43 cooperate with each other to constitute a position adjustment mechanism A of the present invention for mutually adjusting the positions of the lockout plate 30 and the detent plate 34 around the pivot axis of the shift lever 1.

In this way, dimensional errors in each part can be compensated for, and the differential timings of the lockout plate 30 and the detent plate 34 can be reliably synchronized.

Note that, contrary to this illustrated example, even if the detent plate 34 is fixed and the lockout plate 30 is position adjustable around the pivot axis of the shift lever 1 by a position adjustment mechanism having the same structure as the position adjustment mechanism A, can perform similar functions.

If there is a discrepancy between the shift position of the shift lever 1 regulated by the lockout plate 30 and the position of the manual valve of the automatic transmission, operate the turnbuckle 8 to adjust the effective length of the operating wire 4. By doing so, you can correct the inaccuracy.

The lockout plate 30 and the bracket 35 are integrally connected via bridge portions 44 and 45 that cross the front end of the shift lever 1. Furthermore, arm pieces 46 and 47 extending back and forth are welded to the bridge parts 44 and 45, respectively.
6, 47, both ends of the console 48 are screws 49, 4
Fixed at 9.

Referring again to FIGS. 1 and 2, console 4
8 is horizontally provided with a window 50 that passes through the window 50 and allows rotation of the shift lever 1, and this window 50 is closed by a flexible plate-shaped shutter 51. In order to enable the shutter 51 to move back and forth with the rotation of the shift lever 1, a pair of guide grooves 52, 52 for sliding both ends of the shutter 51 together are provided horizontally on the left and right side walls of the window 50. A guide hole 53 for guiding the end of the shutter 51 downward in a curved manner before and after the shutter 50 is continuously provided at both ends of the guide grooves 52, 52.

A through hole 54 that is penetrated by the shift lever 1 is formed in the center of the shutter 51, and a cylindrical cover 55 is provided at the portion that passes through the through hole 54 of the shift lever 1, that is, on the outer periphery of the lever upper part 1b. be coated. In order to fix this cylindrical cover 55, an engaging claw 57 protruding from the lower end thereof is engaged with a locking hole 56 in the lever upper part 1b.

When you turn the shift lever 1, the shutter 5
The through hole 54 and the cylindrical cover 55 move relative to each other with the horizontal movement of the cover 5.
In order to eliminate the gaps between 4 and 55 as much as possible, the following shapes are given to them.

That is, as shown in FIG. 4, the through hole 54 and the cylindrical cover 55 are both formed to have an oval cross section with the major diameter in the direction of rotation of the shift lever 1, and the length of the cylindrical cover 55 is The circular cross-sectional shape is
Over the range of relative movement with the through hole 54, the short axis A is kept constant and the long axis B gradually decreases upward, and when the short axis A and the long axis B are orthogonal to the shift lever 1 and the shutter 51, the through hole It is made almost the same as that of No. 54.

Therefore, when the shift lever 1 comes to a position perpendicular to the shutter 51, the through hole 54 can fit into the lower part, that is, the large diameter part of the cylindrical cover 55, with almost no gap. When the shift lever 1 is rotated from that position, for example, to the right in FIG. However, at the same time, the cylindrical cover 55 tilts toward the chain line positions a and b with respect to the shaft stopper. As a result, in the oval cross section of the cylindrical cover 55 at the fitting part with the through hole 54, the major axis is the same as that of the through hole 54, while the minor axis is originally unchanged, so the shift lever 1 is rotated as described above. Even through movement, the through hole 54 and the cylindrical cover 55 can be maintained in a proper fitted state with almost no gap.

The same applies when the shift lever 1 is rotated to the left in FIG.

C. Effects of the invention As described above, according to the invention, the position adjustment mechanism for mutually adjusting the positions of the lockout plate and the detent plate around the pivot axis of the shift lever is attached to at least one of the two plates. Since it is interposed between the lockout plate and the detent plate, it is possible to compensate for manufacturing errors in each part by adjusting the mutual positions of the lockout plate and detent plate around the shift lever axis, and to ensure that the operating timing of both plates is synchronized. As a result, each part becomes easier to manufacture, leading to improved manufacturing efficiency and cost reduction.
