Technical Field

The utility model belongs to the technical field of the clutch is supplementary.

Background

The clutch is positioned in a flywheel shell between the engine and the gearbox, the clutch assembly is fixed on the rear plane of the flywheel by screws, and the output shaft of the clutch is the input shaft of the gearbox. During the running of the automobile, the driver can press or release the clutch pedal according to the requirement, so that the engine and the gearbox are temporarily separated and gradually jointed, and the power input by the engine to the gearbox is cut off or transmitted. Clutches are common components in mechanical transmissions, and allow the transmission to be disengaged or engaged at any time. The basic requirements for it are: the joint is stable, and the separation is rapid and thorough; the adjustment and the repair are convenient; the overall size is small; the mass is small; the wear resistance is good and the heat dissipation capacity is enough; the operation is convenient and labor-saving, and the common use is divided into a jaw type and a friction type.

The friction clutch transmits torque from the driving shaft to the driven shaft by using mechanical friction force between friction surfaces, and can enable the main engine to be connected with or disconnected from the driven shaft according to working requirements. The friction clutch mainly comprises a disk friction clutch which comprises a driving friction disk and a driven friction disk, the wear resistance of the friction clutch is poor, the sensitivity, the stability and the reliability of the friction clutch are greatly reduced after the friction clutch is used for a long time, and the friction clutch has the defect of short service life.

The friction clutch needs better telescopic capacity in the trampling process, so a distance limiting mechanism is required to be arranged in the clutch, the existing clutch with the distance limiting structure is fewer, is easy to damage, and is short in service life.
