Electric finger type dynamic engagement two-way clutch with damper plate

Abstract

The invention discloses an electric finger type dynamic joint two-way clutch with a buffer disc. When the electric finger pin valve is not energized, under the action of the return spring, the end of the electric finger pin does not touch the end face of the output disc, and the output disc is in a separated state; when the electric finger pin valve is energized, the electric finger pin overcomes the elastic force under the action of electromagnetic force Move towards the direction of the input disc, slide into the arc-shaped ring groove in the rotating state, and push the output disc to rotate synchronously. At the same time, the output disc pushes the buffer disc to rotate through the rubber spring element, so as to realize the synchronous transmission of the input disc and the buffer disc, and the clutch is engaged. The arc-shaped ring groove adopts a structure with deep sides and shallow middle, so that the input disc can rotate synchronously with the output disc in the forward and reverse rotation states, and realize the two-way engagement of the clutch.

Description

technical field [0001] The invention relates to a clutch, more precisely an electric finger type dynamic engagement two-way clutch with a buffer disc. Background technique [0002] Existing electromagnetic clutches can be divided into: friction plate electromagnetic clutches, jaw electromagnetic clutches, magnetic powder clutches, slip electromagnetic clutches and the like. When the friction plate electromagnetic clutch is engaged, the electromagnetic force generated by the electromagnetic coil energization compresses the active friction plate and the driven friction plate to transmit torque. When transmitting large torque, the radial size of the input plate and the driven plate must be increased, Large electromagnetic coil energizing current increases the number of active friction plates and driven friction plates, so there are disadvantages such as large volume, low speed, and high power consumption; the tooth-jaw electromagnetic clutch transmits large torque, and requires...

Problems solved by technology

When the friction plate electromagnetic clutch is engaged, the electromagnetic force generated by the electromagnetic coil energization compresses the active friction plate and the driven friction plate to transmit torque. When transmitting large torque, the radial size of the input plate and the driven plate must be increased, Large electromagnetic coil energizing current increases the number of active friction plates and driven friction plates, so there are disadvantages such as large volume, low speed, and high power consumption; the tooth-jaw electromagnetic clutch transmits large torque, and requires low speed difference when engaging, and there are The disadvantage of not being able to engage at high speed; the magnetic powder clutch has a fast response and can realize fine-tuning of the accuracy according to the magnitude of the current, but there are disadvantages such as high power consumption, high temperature when the slip is large, and high cost; when the slip electromagnetic clutch is working, the main, There must be a certain speed difference in the driven part to transmit torque, and the eddy current in the rotor will generate heat, which is proportional to the speed difference
