Abstract

The invention discloses a disc clutch. The disc clutch comprises a clutch shell and an output shaft of the clutch, the clutch shell is rotatably mounted at the output shaft through a bearing, the clutch shell is provided with a power input structure, the disc clutch further comprises a transmission sleeve, a limiting piece, one or more friction disc sets and a piston which are arranged in the clutch shell, the transmission sleeve fixedly sleeves the output shaft, the limiting piece fixedly sleeves the transmission sleeve, the piston slidably sleeves the transmission sleeve, the friction disc sets are located between the limiting piece and the piston and comprise inner friction discs and outer friction discs, the outer friction discs are in transmission connection with the clutch shell, theinner friction discs are in transmission connection with the transmission sleeve, an elastic piece for driving the piston to reset is arranged between the piston and the transmission sleeve, and theside, away from the friction disc sets, of the piston is provided with a piston power mechanism for driving the piston to move. The clutch has the advantages of small size and large transmitted torque, and the need of a large-diameter cooling fan is met.

Description

Technical field

[0001] The invention relates to the technical field of engines, in particular to a disc clutch. Background technique

[0002] With the continuous upgrading of emissions, the thermal load of the engine continues to increase, and the amount of heat that needs to be taken away by the cooling system has also increased significantly. The diameter of the fan used in the cooling system also needs to continue to increase, which requires the clutch driving the fan to be able to transmit large Torque.

[0003] There are many types of fan clutches, such as silicon oil clutches, electromagnetic clutches, pneumatic clutches and hydraulic clutches, but they generally have the shortcoming of small transmitted torque. Most of the transmitted torque is below 200N·m, which cannot meet the driving requirements of large-diameter fans. The clutch has the disadvantage of large size. For example, the fan clutch that transmits about 200N·m has an external size of 250mm or more. Some hydra...
