Abstract

The invention relates to a combined clutch of an automotive AMT (Automated Mechanical Transmission). The combined clutch of the automotive AMT comprises a housing, an engine power output shaft, a gear transmission input shaft, a hydraulic transmission device and a one-way clutch; the hydraulic transmission device is a hydraulic torque converter with a locking device or the hydraulic transmission device is a device which is formed by a hydraulic coupling and a friction clutch A; a pump wheel and a turbine of the hydraulic coupling can be locked into a whole through the friction clutch A; the engine power output shaft is connected with the hydraulic transmission device; the hydraulic transmission device is connected with the one-way clutch; the one-way clutch is connected with the gear transmission input shaft and provided with a friction clutch B; an inner ring and an outer ring of the one-way clutch can be locked into a whole through the friction clutch B. According to the combined clutch of the automotive AMT, an automobile can start smoothly, the problem that impact on shifting is caused by power interruption in the process of the shifting of the automobile is solved, the structure is simple, the cost is low, and the wide popularization and application can be convenient.

Description

technical field [0001] The invention relates to a clutch, in particular to a combined clutch of an automobile AMT automatic transmission. Background technique [0002] An automatic transmission with a microcomputer automatic shift device installed on the basis of a manual transmission car, referred to as AMT. Compared with other automotive automatic transmissions, AMT has the advantages of high transmission efficiency, fuel saving, simple structure, low production cost, and convenient maintenance. However, the biggest disadvantage of AMT is that it is extremely difficult to control the dry friction clutch, resulting in poor starting smoothness of the car, and the interruption of power during the shifting process causes shock (feeling of frustration) in shifting, which affects the ride comfort of the car and hinders Wide application of AMT. [0003] Although the currently disclosed patent No. "CN201443584" also uses a fluid coupling and a one-way clutch to solve the problem...
