Abstract

The invention relates to an electric coupling-type gearshift comprising a splined hub, a synchronous ring, a coupling, a positioning slider, an actuator fixing plate and an electromagnetic linear actuator. A rotor of the electromagnetic linear actuator idly sleeves a coupling groove. During moving, the rotor abuts to the end face of the coupling groove. Fixing protrusions of an actuator sleeve are fitted to slots of the actuator fixing plate; the actuator sleeve is connected with a transmission housing through connecting holes of the actuator fixing plate. The electric coupling-type gearshift is suitable for mechanical automatic transmission systems, especially those with limited arrangement space and having the requirement for further reducing the size of a transmission; by the application of the electric coupling-type gearshift, power interrupt time is shortened, dynamic response speed of a system is increased and shifting energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of gear shifting, in particular to an electric clutch-type shifting mechanism. Background technique [0002] With the rapid development of electronic power technology, automatic transmission technology is more and more applied to the transmission system. The electromechanical automatic transmission (AMT) is developed from the traditional manual transmission. It has low cost and high transmission efficiency. It has the advantages of compact structure and other advantages, but there are also problems such as long power interruption time and large shifting impact. [0003] The AMT currently researched and developed mainly uses electro-hydraulic drive devices, electric drive devices or rotating motors to directly drive the transmission shift shaft through the motion conversion mechanism. The transmission line is long, and the application is limited by the limited layout of the transmission. space. In recent ye...
