Title Electronically controlled clutch technology research of automobile

Abstract Automatic clutch is a key component of automotive mechanical automatic transmission system. It directly affects the clutch control effect whether its implementing agencies can quickly and accurately respond to the directives issued by the control system or not. Designing automatic clutch actualor with fast response, small tracking error and stable performance is the effect ways to improve the overall performance of automatic clutch. In this paper, AMT electric clutch actuator for the study, automatic mechanical transmission (AMT) is a manual transmission (MT), based on the increase in the clutch and shift actuator selection adapted from, the development of AMT technology easy to implement. This paper mainly focus on the following aspects of:

(1) Analyze the handing characteristics of dry type diaphragm spring clutch and calculate the boundary conditions of clutch actuator such as separation force and the separation displacement.

(2)Demonstrate the feasibility of applying electromagnetic linear actuator on electronic control.

(3)Design technical solutions of electronically controlled clutch actuator according to the defined boundary conditions of actuator.

(4)Establish three-dimensional model of the implementing agencies.

(5) Drawing two-dimensional actuator assembly drawing and parts diagram.

Keywords：Dry clutch, control law, electromagnetic linear actuator, force motion analysis, floor Plan and three-dimensional map.
