Abstract

PURPOSE:To prevent a clutch pedal from following an actuator by pivotally supporting plural numbers of levers coaxially, which are interlocked with a clutch pedal and an actuator respectively, and thereby letting the levers be locked only when a clutch is disengaged via an adapter. CONSTITUTION:When a clutch pedal 8 is depressed while an automatic transmission is switched over to a manual mode, No.1 lever 4 is rotated clockwise, which situation thereby permits an adapter 10 to be pulled into the same direction, and also permits it to be concurrently pulled by a clutch releasing member 14 via No.2 wire 11 so that a clutch 13 is disengaged. On the other hand, when the automatic transmission is switched over to an automatic mode, a rod 9 is shortened by an actuator 1 so as to let No.2 lever 5 be rotated clockwise, which situation thereby permits the adapter 10 to be pulled into the same direction similarly as described above so that the clutch 13 is disengaged. During the period of the time, No.1 lever 4 is maintained at the position A with no rotation provided, the clutch pedal 8 is thereby kept in a state corresponding to clutch engagement.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a clutch operating device, and more particularly to a latch operating device that can be operated on and off by both a clutch pedal and an actuator.

(Prior Art) Conventionally, this type of clutch operation device has been used for clutch operation of a transmission having both automatic shift change and manual shift change functions, and as shown in FIG. It has a first wire 52 that connects the clutch release member 51, a second wire 54 that connects the clutch pedal 50 and the actuator 53, and a lever 55.

With such a latch operating device, when the manual shifter is engaged, the clutch pedal 5 is
When the lever 55 is rotated in the direction of the arrow in the figure by the actuator 53 during an automatic shift change, the clutch pedal 50 is moved by the second wire 54 when the clutch pedal 50 is depressed. The first wire 52 is moved in the same direction as the
is pulled in the same way, causing the clutch to disconnect.

(Problems to be Solved by the Invention) However, in the conventional clutch operating device described above, when the actuator 53 is actuated, the clutch pedal 50 also moves following the operation, which is a problem that bothers the driver and causes discomfort. was.

(Means for Solving the Problems) In view of the drawbacks of the prior art described above, the clutch operating device of the present invention has a first lever interlocked with a clutch pedal and a second lever interlocked with the actuator, which are substantially fixed to a fixed part. the first lever and the second lever are coaxially supported;
The adapter is fully connected to the clutch release member and biased toward the clutch connection side, and is configured to lock only in the clutch disengagement direction via a common locking portion.

(Function) In the clutch operating device of the present invention, when the clutch pedal is not depressed and the actuator is not activated, the first lever and the second lever are engaged with the common locking portion of the swallowtail lever by the urging force applied via the adapter. Both are in a locked state. In this state, when the clutch pedal is depressed against the biasing force and the first lever is rotated in the clutch disengagement direction, the clutch release member is pulled in the clutch disengagement direction via the adapter, and the clutch is disengaged.

At this time, the swallowtail will move following the rotation of the first lever, but the swallowtail will move the first /\- and second levers in the clutch disengagement direction -C 4. (F + Since the second lever is to stop, the second lever is affected by the movement of the swallowtail.) The actuator operates and moves the second lever in the direction of clamping Similarly, when the first lever is rotated , the first lever remains in its original position.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 to 4. The embodiment relates to a clutch operating device for a vehicle manual transmission (not shown) having both the above-described automatic shift change and manual shift change functions.

In FIG. 1, an actuator 1 is attached to an actuator attachment plow 2 fixed to an appropriate location on a vehicle. A lever support bracket 3 is further fixed to the actuator mounting bracket 2, and a first lever 4 and a second lever 5 are attached to the lever support bracket 3.
The bolt 6 that coaxially supports the and is not fully secured.

The first lever 4 has upper and lower art parts 4a and 4b centered around the axis of the bolt 6, and the lower end of the lower arm part 4b is connected to the clutch pedal 8 via the first wire 7.

The second lever 5 has its lower end pivotally supported by the shaft of the bolt 6, and its length is set to be approximately the same length as the upper arm portion 4a of the first lever 4. The tip of the rod 9 of the actuator 1 is rotatably connected to the center of the second lever 5, and the second lever
The zero rotation angle range is set to be the same as the rotation angle range of the first lever 4 when the clutch pedal 8 is depressed and released (such an angle range is indicated by α in Fig. 1). ).

10 is an adapter that locks the upper ends of the first lever 4 and the second lever 5, and is connected to one end of the second wire 11, and the other end of the second wire 11 is connected to the clutch release member 14 of the clutch body 13. The connection is broken.

Next, the configuration of the adapter 10 will be explained in detail with reference to FIG. 2. As shown in FIG.
0a is approximately U-shaped, and the above-mentioned second
The ends of the wires 11 are connected. Further, a bin 15 is attached between the open ends of the U-shape of the main body 10a, and this bin 15 is used to disengage the clutch from the upper ends 4c and 5a of the first lever 4 and the second lever 5, as will be explained later. It is configured to lock only in the direction.

That is, when the swallowtail piglet 10 is in a state where the first lever 4 and the second lever 5 are located at position A in FIG.
and the upper ends 4c and 5a of the second lever 5 are simultaneously locked via the pin 15 as shown in FIG. When the first lever 4 or the second lever 5 is rotated toward the B position in FIG. 1, the second wire 11 is pulled and clutched, and the lease member 14 is moved to disengage the clutch. In other words, the rotation from the A position to the B position in FIG.
And the second lever 5 is locked only in the clutch disengagement direction. Moreover, the upper end portions 4c of the first lever 4 and the second lever 5,
5a is formed into a hook shape that extends beyond the top of the pin 15 when engaged by the pin 15.

In the clutch operating device configured as described above, when the automatic transmission is set to manual shift change mode and the clutch pedal 8 is depressed, the first shifter 4 rotates clockwise in the figure, and the adapter 10 rotates clockwise in the figure. It is pulled in the same direction via the pin 15, and in turn, the -C clutch release member 14 is pulled via the second wire 11, and the ramp is cut off. Here, before the clutch pedal 8 is depressed, the first lever 4. Both of the second levers 5 are engaged with the pins 15, and when the clutch pedal 8 is depressed, the adapter 10 is moved to the first lever 4.
(j), since the second lever 5 is locked by force in the clutch disengagement direction,
The first lever 4 is still in the A position in FIG.
The adapter 10 and the first
The relative positional relationship between the lever 4 and the tips 4a and 5a of the second lever 5 is as shown in FIG. do not have.

Next, when the automatic transmission is set to the automatic shift change mode, the clutch is engaged and engaged when the rod 9 is contracted by the actuator 1 and the second lever 5 is rotated clockwise in the figure. Similarly, adapter 1
0 is pulled in the same direction via pin 15, and the clutch is disengaged. During this time, the first lever 4 still maintains the A position in FIG. 1, and the second lever 5 rotates to the B position in FIG.

The adapter 10, the first lever 4, and the second lever 5 in the
The relative positional relationship with the tips 4a and 5a of the clutch I is as shown in FIG. drooping

(Effects of the Invention) In the clutch operating device of the present invention, even if the actuator operates, the second lever that is linked to the clutch pedal does not move, and therefore the clutch pedal does not move either, so the driver does not have to pay attention to the clutch pedal. It has the advantage of allowing comfortable driving.
