Description

a clutch

technical field

The utility model relates to the technical field of clutches, in particular to a clutch.

Background technique

The clutch is a component directly connected with the engine in the car transmission system. It is responsible for the cut-off and combination of the power and the transmission system, so it can ensure the smooth start of the car when starting, and also ensure the smoothness of the gear shift. It also prevents the transmission system from overload. The clutch is a transmission mechanism. It has an active part and a driven part. The two parts can be temporarily separated or slowly combined, and there may be relative rotation during the transmission process. Therefore, between the active part and the driven part of the clutch It will rely on contact friction to transmit torque, or use the pressing force required by friction, or use liquid as the transmission medium, or use magnetic transmission to transmit torque.

What is widely used on automobiles at present is exactly the friction clutch that relies on spring (or diaphragm spring) to compress. When the car is running, it needs to keep the transmission of power frequently. Interrupting the power is only a temporary need. Therefore, the active and driven parts are in a combined state for a long time during the driving process. When the driver depresses the clutch pedal, through the transmission of the parts, Separate the driven part from the driving part.

However, the existing clutch usually uses a release hook to connect the pressure plate to the diaphragm spring. When the clutch pedal is stepped on, the pressure plate is driven by the release hook to separate the pressure plate from the driven plate, thereby realizing the separation between the driven plate and the driven plate. Separation of the flywheel. The release hook used in the prior art will be plastically deformed or broken during long-term use, resulting in incomplete separation of the clutch, reducing the life of the clutch, and even causing the gear shifting of the reducer to occur.

Therefore, in order to solve the above-mentioned technical problems, a clutch that ensures the compression and separation of the pressure plate to the driven plate and prolongs the service life of the clutch is needed.
