Description

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

(Prior Art) Conventionally, this type of clutch operating device has been used to operate the clutch of a transmission that has both automatic shift change and manual shift change functions.
As shown in FIG. 5, a first wire 52 connects the clutch pedal 50 and the clutch release member 51.
, a second wire 54 that connects the clutch pedal 50 and the actuator 53, and a lever 55.

In such a clutch operation device, when a manual shift change is performed, when the clutch pedal 50 is depressed from the clutch connected state shown in the figure, the first wire 52 is pulled and the clutch is disconnected, and during an automatic shift change, the actuator 53 operates the lever 55. When the clutch pedal 50 is rotated in the direction of the arrow in the figure, the clutch pedal 50 is moved by the second wire 54 in the same direction as when it is depressed, and along with this, the first wire 52
is similarly pulled so that the clutch is disconnected.

(Problems to be Solved by the Invention) However, the conventional clutch operating device described above has the disadvantage that when the actuator 53 is activated, the clutch pedal 50 also moves following the operation, which bothers the driver and causes discomfort. had.

(Means for Solving the Problems) In view of the above drawbacks of the prior art, the clutch operating device of the present invention provides a clutch operating device in which a first lever interlocking with a clutch pedal and a second lever interlocking with an actuator are arranged substantially coaxially to a fixed part. The lengths from the pivot shaft to the upper ends of the first and second levers are set to be approximately the same length so that the rotation angle range between the pivot shaft and the fulcrum is the same. In addition, the upper end of the first lever and the upper end of the second lever are attached to the open end of a U-shaped adapter whose closed end is connected to a clutch release member and biased toward the clutch connection side. The structure is such that they are respectively locked inside the pins.

(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 both locked to the pin of the adapter by the biasing force applied through the adapter. It is in a state of In this state, when the clutch pedal is depressed against the biasing force and the first lever is rotated in the clutch disengaging direction, the clutch release member is pulled in the clutch disengaging direction via the adapter, and the clutch is disengaged. At this time, the adapter moves following the rotation of the first lever, but the second lever is not affected by the movement of the adapter and remains at its original position. On the other hand, when the actuator operates to rotate the second lever in the clutch disengaging direction, the first lever similarly remains at its original position.

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

In FIG. 1, an actuator 1 is attached to an actuator mounting bracket 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 bolt 6 for coaxially supporting the first lever 4 and the second lever 5 is fixed to the lever support bracket 3.

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

The second lever 5 has its lower end pivotally supported by the shaft of a bolt 6, and its length is set to be approximately the same length as the upper arm portion 4a of the first lever 4. Second
The tip of the rod 9 of the actuator 1 is rotatably connected to the center of the lever 5, and the rotation angle range of the second lever 5 as the rod 9 expands and contracts depends on the depression and release of the clutch pedal 8. (Such an angular 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. connected.

Next, the configuration of the adapter 10 will be explained in detail with reference to FIG. 2. As shown in the figure, the main body 10a of the adapter 10 is approximately U-shaped.
The end of the second wire 11 is connected to the closed end of the letter. Further, a pin 15 is attached between the open ends of the U-shape of the main body 10a, and this pin 15 is attached to the upper end portion 4 of the first lever 4 and the second lever 5.
c, 5a are configured to be locked only in the clutch disengagement direction, as will be explained later.

That is, the adapter 10 is attached to the upper end portion 4 of the first lever 4 and the second lever 5 when the first lever 4 and the second lever 5 are located at position A in FIG.
c and 5a are simultaneously locked via the pin 15 as shown in FIG. 2, and in this state, the second wire 1
1 is set to keep the clutch connected in a tensioned state, and the first lever 4 or the second lever 5
is rotated to the B position side in FIG. 1, the second wire 11
is pulled, the clutch release member 14 is moved, and the clutch is released. In other words, the rotation from the A position to the B position in FIG. Locks only in the direction. Also, the first
The upper ends 4c and 5a of the lever 4 and the second lever 5 are formed into hook shapes that extend beyond the upper part 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 lever 4 rotates clockwise in the figure, thereby causing the adapter 10 to move toward the pin 15. The clutch release member 14 is pulled in the same direction via the second wire 11, and the clutch is released. Here, before the clutch pedal 8 is depressed, both the first lever 4 and the second lever 5 are engaged with the pin 15 as shown in FIG.
moves following the first lever 4, but since the second lever 5 is locked only in the clutch disengagement direction, it still remains at position A in FIG. Adapter 10 and first lever 4 when rotated to position B in Figure 1
The relative positional relationship between the tip portions 4a and 5a of the second lever 5 is as shown in FIG. 3, the second lever 5 does not rotate, and the actuator 1 is not affected in any way.

Next, when the automatic transmission is set to automatic shift change mode, the clutch is engaged and engaged by actuating the actuator 1, which retracts the rod 9 and rotates the second lever 5 clockwise in the figure, as in the case of the manual shift change described above. Then the adapter 10 is pulled in the same direction via the 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 relative positional relationship with 4a and 5a is as shown in FIG. 4, and since the first lever 4 does not rotate, the clutch pedal 8 is maintained in a state corresponding to the clutch connected state.

(Effects of the Invention) In the clutch operation device of the present invention, even if the actuator is activated, the first lever that is linked to the clutch pedal does not move, and therefore the clutch pedal does not move either, so the driver is not distracted by the clutch pedal. It has the advantage of allowing comfortable driving without any hassle.
