Double-plate self-adjusting clutch for AMT automobile

Abstract

The invention discloses a double-plate self-adjusting clutch for an AMT automobile, and belongs to the technical field of automobile parts. The double-plate self-adjusting clutch comprises a diaphragm spring, a main pressure plate, an inner driven plate, a middle pressure plate and an outer driven plate which are sequentially arranged in a shell, a torque transmission assembly connected with the main pressure plate and the middle pressure plate is arranged on the periphery of the shell, the diaphragm spring is connected with the shell through a connecting assembly, and the inner side face of the edge of the diaphragm spring abuts against the outer end face of an adjusting ring; and an automatic wear compensation mechanism is arranged between the adjusting ring and the main pressure plate. According to the invention, the torque transmission capability is improved through the double-plate clutch, and the phenomena of vehicle shaking and the like caused by insufficient torque transmission capability are avoided; the heat capacity of the clutch is increased by utilizing the two pressure plates, the allowable abrasion thickness is multiplied, and the service life of the clutch is prolonged; and the automatic wear compensation mechanism can guarantee that the distance between a separation finger tip of the diaphragm spring and a flywheel is kept unchanged, the defect that the position of the clutch is not accurately controlled is overcome, the control speed of an AMT system is increased, and clutch and gear shifting are stable and rapid.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, in particular to a double-plate self-adjusting clutch for an AMT automobile. Background technique [0002] Existing AMT heavy-duty truck clutches will encounter bottlenecks when matching higher power engines. The main problems are insufficient torque transmission capacity for high torque, vibration when starting on a slope, and insufficient service life. The specific performance is in the following aspects: [0003] 1. The transmission torque capacity of the matching high-power engine is not enough, and the starting vibration and slippage appear when driving on the slope; [0004] 2. The heat dissipation performance of the clutch is poor, and when the temperature is high, the clutch alarm will appear in the control system, which will delay normal driving; [0005] 3. The allowable wear thickness of the friction plate is relatively small, and the service life is still not long enough. ...
