AI Technical Summary

Technical Problem

Existing dynamic controllable clutch (DCC) actuation systems are complex. Hydraulic actuation systems are unstable in hot oil environments, have slow response times, high energy consumption, and can only move in one direction, requiring a spring to provide the return stroke.

Method used

A switchable linear actuator device is used to generate net translational force by using an electromagnetic source and a permanent magnet source. The force is moved in the axial direction through a converter structure to achieve selective small displacement of the locking component. Combined with permanent magnet locking technology, the structure is simplified and the efficiency is improved.

Benefits of technology

The structure of the dynamic clutch has been simplified, the response speed and energy efficiency have been improved, energy consumption has been reduced, component wear and noise have been reduced, and the overall packaging and response time have been improved.

Abstract

This invention provides an electrodynamic coupling and control assembly and a switchable linear actuator device. The assembly has a first coupling member and a second coupling member, each supported for rotation about a common axis of rotation, and at least one locking member for selectively mechanically coupling the coupling members together. The device includes: a stator structure including at least one electromagnetic source; and a converter structure configured to be coupled to the second coupling member for rotation therewith. The converter structure includes at least one plunger that is elastically deformable in the axial direction to provide compliance to the device. Each plunger has a free end portion configured to move within a channel to engage and actuate the locking member within a slot of the second coupling member.
