Execution mechanism for dry-type dual-clutch automatic transmission rack

Abstract

The invention relates to an execution mechanism for a dry-type dual-clutch automatic transmission rack. The execution mechanism comprises a test platform (2), a bearing carrier pressure plate (3), a clutch diaphragm spring (5), a clutch separation bearing, a lower support plate (12), a transmission screw (18), a transmission nut (17), a first transmission gear (15), a second transmission gear (1), an upper support plate (19), a drive motor (29) and a displacement amplifying component. Compared with the prior art, the execution mechanism provided by the invention has the advantages of actually simulating the actuation process of a dry-type dual clutch transmission (DCT) to reflect the dynamic characteristics of a clutch execution mechanism of a real vehicle, etc.

Description

technical field [0001] The invention relates to a technology related to a dry double-clutch automatic transmission, in particular to an actuator for a dry-type double-clutch automatic transmission stand. Background technique [0002] The dual-clutch automatic transmission (DCT) can ensure that the power output is not interrupted during the shifting process, which is conducive to improving the shifting quality. At present, DCT clutch actuators mainly have three structural forms: electronically controlled pneumatic, electronically controlled hydraulic and electronically controlled electric. The electronically controlled electric actuator has the advantages of fast response, simple structure, high transmission efficiency, and low manufacturing cost. widely used. [0003] A typical electronically controlled electric clutch actuator has two structures, one is mainly composed of a DC motor, a helical transmission mechanism, a helical booster spring, a hydraulic transmission mecha...
