A buffer device for transmission

Abstract

The invention relates to the field of transmissions, in particular to a buffer device for a transmission, comprising an outer ring and a friction disc; the friction disc is located in the middle of the outer ring, and a plurality of buffer blocks are uniformly arranged on the edge of the friction disc; There is a buffer cavity corresponding to the buffer block in the outer ring, the buffer block is slidably connected in the buffer cavity, and one end of the buffer block is elastically connected to the inner wall of the buffer cavity through a spring; there is also a buffer cavity inside the outer ring. The oil chamber corresponding to the cavity, the two ends of the oil chamber communicate with the two ends of the buffer chamber through the first hole, and there is also a second hole between the buffer chamber and the oil chamber; the beneficial effect of the present invention is that: when the clutch plate and When the friction disc is attached, the hydraulic oil can flow in the buffer chamber and the oil chamber to play a buffer effect between the friction disc and the outer ring. The second hole and the third hole play a role of pressure relief to prevent the clutch plate At the moment of fitting with the friction disc, the pressure of the hydraulic oil rises sharply, resulting in damage to the outer ring.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a buffer device for a transmission. Background technique [0002] When the vehicle shifts gears, the clutch plate and friction disc in the transmission generally need to be separated first, and then fit together after the gear shift is completed. Since the clutch plate is directly connected to the power input shaft of the engine, the friction disc is directly connected to the power output shaft of the transmission. Therefore, the speed gap between the clutch plate and the friction disc is relatively large, and the moment the two are attached will cause an impact on the power output shaft of the transmission, and may cause damage to the internal structure of the transmission after long-term use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a buffering device for a transmission which can avoid the shock caused to the tra...
