1. Conducive to the start of the car
The vehicle is stationary before running. Since the engine and the transmission are rigidly connected, once the gear is engaged, the vehicle will suddenly rush forward due to the sudden connection of the driving force, which will not only cause damage to the parts, but also the power cannot escape the engine. The large moment of inertia generated by the forward rush of the motor car causes the engine power to drop sharply and stop the fire.
If you use the car clutch to temporarily separate the generator from the transmission at the start, then the car clutch is gradually connected tightly, because there is a general slippage between the active part of the car clutch and the driven part, which can make the torque issued by the car clutch. Slowly expand from zero, and the driving force of the car gradually expands, thereby allowing the vehicle to develop stably.
2. It is convenient to shift the car
During the entire driving process of the vehicle, gear shifting is often involved to meet the requirements of different driving environments, and in the case of shifting gears, the clutch will be used.
The clutch can separate the automobile engine from the transmission. The clutch is used to separate the automobile engine and the transmission to complete the shift. Then the pair of transmission gears that were originally meshed are removed due to the load, and the burden between the meshing surfaces is greatly reduced. It is easy to separate. If there is no clutch, the pressure between the tooth surfaces is too large and it is not easy to separate, and it is very easy to damage the parts.
3. Prevent the transmission system from being damaged due to excessive pressure
When the vehicle is stopped in an emergency, the wheel suddenly decelerates greatly, and the gear train connected to the car engine still maintains the original speed ratio due to the inertial force of rotation, which often occurs in the braking system. The torque is much higher than the car engine torque. The high bending stiffness makes the parts of the rotating system very easy to damage.
4. Reduce torsional shock
The output torque of the car engine is usually not stable. The engine is in the running stroke. The inertia of the engine's rotating system can reduce the torsional vibration, but the remaining impact force still has an adverse effect on the subsequent gearbox and drive shaft, and the clutch in the clutch. The vibration damping spring can significantly reduce the torsional vibration impact produced by the automobile engine and increase the service life of the acceleration gear.
The clutch is located in the flywheel housing between the automobile engine and the transmission. The clutch bearing is fixed on the rear surface of the axle with screws. The input and output shaft of the clutch is the input shaft of the transmission.
During the driving process of the motor vehicle, the driver can step on or release the clutch pedal according to the needs, so that the car engine and the transmission are currently separated and gradually tightly connected, so as to disconnect or transmit the driving force input by the car engine to the gearbox.
Clutch is a common component in gear transmission, which can disengage or tightly connect the transmission at any time and place.
