Electric control silicone oil clutch structure with separated magnetic circuits

Abstract

The invention discloses a magnetic circuit separated electric control silicone oil clutch structure which comprises a front cover, a driving plate, a driven plate, a shell, a driving shaft and a valve plate assembly. A sliding block, a sealing block and a piston rod are arranged in the driving shaft, and the sliding block is arranged at the upper end of the sealing block; the piston rod is arranged between the upper portions of the sliding blocks and extends upwards to be connected with the valve plate assembly, the periphery of the piston rod is sleeved with a spring and a copper sleeve, and the spring is located between the valve plate assembly and the copper sleeve. A magnetic circuit separation structure is adopted, the magnetic circuit and the valve plate assembly are independently separated, the structural design of the valve plate assembly and the structural layout of the working cavity are completely not limited by the magnetic circuit, the design is simpler and more convenient, meanwhile, the valve plate assembly is in a weak magnetic or non-magnetic state in the working process, opening and closing of the valve plate assembly are smoother, and the service life of the valve plate assembly is prolonged. And the performance deviation of the clutch caused by the switching stroke of the valve plate assembly and the residual magnetism intensity is avoided, and the consistency of products is improved.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to an electrically controlled silicon oil clutch structure for magnetic circuit separation. Background technique [0002] At present, the traditional electronically controlled silicone oil clutch cannot avoid the design interference of the magnetic circuit in the design of the valve plate and the internal configuration design. The magnetic force must be transmitted through the valve plate to form a closed loop, which makes the structural design of the valve plate and the structural layout of the working chamber affected. The magnetic circuit is restricted, and the loss of the magnetic circuit is large. At the same time, because the magnetic circuit needs to pass through the valve plate, the valve plate is in a strong magnetic state, so that the opening and closing of the valve plate is not straightforward, resulting in easy deviation of the clutch performance.

[0002] At present, the traditional electronically controlled silicone oil clutch cannot avoid the design interference of the magnetic circuit in the design of the valve plate and the internal configuration design.

The magnetic circuit is restricted, and the loss of the magnetic circuit is large. At the same time, because the magnetic circuit needs to pass through the valve plate, the valve plate is in a strong magnetic state, so that the opening and closing of the valve plate is not straightforward, resulting in easy deviation of the clutch performance.
