Technical Field

The invention relates to an automobile clutch, in particular to a clutch shell.

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.

However, the existing clutch housing is cast by using an aluminum alloy product in order to have a good heat dissipation effect, but although the cast aluminum alloy product has good heat dissipation and plasticity, the wear resistance is not guaranteed, the clutch housing is easy to damage, the clutch housing is not easy to repair after being damaged, and the whole clutch housing needs to be replaced when the whole clutch housing is damaged.
