Clutch assembly of crane power device

Abstract

The invention relates to the field of clutches, in particular to a clutch assembly of a crane power device. The clutch assembly of the crane power device has the advantages that heat dissipation is rapid, the contact area of a clutch plate is increased, and the damping stroke is large. According to the technical scheme, the clutch assembly of the crane power device comprises a flywheel, friction discs, damping mechanisms, a fixing box, an extrusion mechanism, a third spring and the clutch plate; the extrusion mechanism is arranged in the fixing box, the fixing box is fixedly connected with the flywheel, the number of the friction discs and the number of the damping mechanisms are two respectively, one friction disc and one damping mechanism are arranged in the fly wheel while the other friction disc and the other damping mechanism are arranged in the extrusion mechanism, the two friction discs are rotationally connected with the flywheel and the extrusion mechanism respectively, the two friction discs are fixedly connected with the two damping mechanisms, and the two friction discs clamp the clutch plate through the extrusion force of the third spring on the extrusion mechanism. According to the clutch assembly, rotation buffering of the friction discs and the clutch plate is realized through the damping mechanisms.

Description

technical field [0001] The invention relates to the field of clutches, in particular to a clutch assembly of a crane power device. Background technique [0002] The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, so as to cut off or transmit the power input from the engine to the transmission. Clutches are common components in mechanical transmissions that can disengage or engage the transmission system at any time. [0003] The existing crane clutch is basically similar to the traditional automobile clutch. Because the crane is a special hoisting machinery, the curb weight of the crane itself is very large. Due to the unc...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the clutch plate damping device of the existing clutch, it is installed at the center of the clutch plate, which reduces the contact area between the clutch plate, the pressure plate and the flywheel. Due to the limitation of the clutch plate, the damping stroke of the shock absorbing spring is very small. , resulting in poor shock absorption performance. At the start of the crane, the clutch plate is in a semi-linkage state. The flywheel, pressure plate and clutch plate rotate and rub at high speed, which makes the flywheel, pressure plate and clutch plate heat up rapidly, and the flywheel and pressure plate dissipate heat. The flywheel and the pressure plate are burned and deformed, and the high-temperature flywheel and the pressure plate will burn and carbonize the clutch plate, resulting in damage to the clutch plate. The technical problem to be solved is: to provide a fast heat dissipation, increase the contact area of ​​the clutch plate and Clutch assembly of crane power unit with large shock absorbing stroke
