introduction:1、Make sure the car starts smoothly This is the primary function of the clutch。Before the car started,Naturally, you start the engine first。And when the car starts,The car accelerated gradually from a complete standstill。If drive train(It connects the whole car)Rigidly connected to the engine,Once the transmission is in gear,The car will make a sudden leap forward,But it doesnt get started。This is because the car goes from standstill to forward thrust,It has a lot of inertia,It creates a large drag moment on the engine。Under this inertial resistance moment,The engine speed drops sharply to the lowest stable speed in an instant(normal300-500RPM)below,

introduction: Separate type bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Because the inner ring and the outer ring can be conveniently installed on the shaft or bearing seat respectively。At this time, it should be noted that the shaft that has been installed with the inner ring is inserted into the bearing box that has been installed with the outer ring,Try to keep them together,To prevent chafing of rollers and raceways。rightKOYObearing[K
