Description

[Detailed Description of the Invention] This invention relates to a clutch operating device for a vehicle that facilitates maintaining a half-clutch state.

Generally, in a vehicle in which a clutch in a power system is controlled on and off by a clutch pedal, a shudder phenomenon occurs when the vehicle starts.

This is because when the latch disc, which has a large coefficient of friction, is turned on and off by operating the clutch pedal, the impact caused by the friction of the lining causes self-excited vibrations, and this self-excited vibration causes the vehicle to start with a jerking shock. As a result, the riding comfort of the vehicle deteriorates, and the impact also causes the vehicle to be held in a half-clutched state.

Since the feet are also swung up and down, it becomes difficult to maintain the half-clutch state, causing a problem in which the impact is further amplified.

This idea was made with the aim of improving this problem.The fulcrum part of the clutch pedal is equipped with a shock absorbing mechanism, and the foot that maintains the half-clutch state becomes unstable due to the impact of soil removal when the vehicle starts. To provide a clutch operating device for a vehicle which is prevented from swinging, thereby making it easy to maintain a half-clutch state and making it possible to start the vehicle smoothly.

This invention will be described in detail below with reference to an illustrated embodiment.

In the figure, 1 is a driver's seat of a vehicle, and an arm 3a of a clutch pedal 3 is provided in front of the driver's seat 1 to protrude from a groove 2a of a floor plate 2.

The proximal boss portion 3b of the clutch arm 3a is rotatably supported at the intermediate portion of a support shaft 5 whose one end is fixed to the vehicle body 4 below the floor plate 2, and at the distal end side of the support shaft 5. A friction plate 6 pressed against the end surface of the post 3b portion of the clutch arm 3a, a spring body 7 such as a disc spring that urges the friction plate 6 toward the boss 3b, and a spring seat 8 are inserted in this order, and the support shaft 5
At the tip of the nut 10 is secured by a split pin 9.
are screwed together so that they can be adjusted freely.

Further, one end of a connecting rod 11 and a tension spring 1 are attached to the tip side of a lever 3c protruding from the circumferential surface of a post 3b of the clutch arm 3a.
2 are connected to each other, and a tension spring 12 urges the tip side of the clutch arm 3a, that is, the clutch pedal 3 side, to return upward, and the other end of the connecting rod 11 is mounted on the vehicle. It is connected to the tip of the clutch lever 14 of the clutch 13.

Since this invention has been described in detail above, the clutch 13 can be engaged and engaged in the conventional manner by depressing the clutch pedal 3, and the friction plate 6 biased by the spring body 7 can be moved to the position 3b of the clutch arm 3a. Since it is pressed against the end surface, even if an impact is applied from the vehicle body 4 when the clutch pedal 3 is placed in a partially engaged state with the foot on the clutch pedal 3, the impact is absorbed between the boss 3b and the friction plate 6. Since this is absorbed by friction, the foot on the clutch pedal 3 does not swing unstably due to the impact, and as a result, the half-clutch state is unstable and the clutch 13 is disengaged.
Problems such as further amplification of the impact on the vehicle body 4 can be reliably prevented.

Further, since it is only necessary to add the friction plate 6 and the spring body 7 to the support shaft 5 portion of the clutch arm 3a, it can be implemented easily and inexpensively.
