Transmission connecting shaft clutch mechanism based on magnetorheological fluid

Abstract

The invention relates to the technical field of clutch transmission mechanisms, and discloses a transmission connecting shaft clutch mechanism based on a magnetorheological fluid. The mechanism comprises a transmission main shaft, wherein a mounting inner groove is formed in one side of the middle of an inner cavity of the transmission main shaft, a movable pressing rod is movably arranged on theinner wall of the mounting inner groove in a sleeve mode, the movable pressing rod is in transmission connection with one side of the inner wall of the mounting inner groove through a reset spring, atransmission groove hole is formed inside one side of the outer surface of the transmission main shaft, and an electromagnetic coil is fixedly mounted on the left side of the outer surface of a transmission driven shaft and located on the outer edge of the transmission groove hole. According to the transmission connecting shaft clutch mechanism based on the magnetorheological fluid, through arrangement of the mounting inner groove, the movable pressing rod and the reset spring, a magnetorheological fluid on one side of the inner cavity of the transmission main shaft can be discharged out of the transmission main shaft when power is separated, so that damping friction caused by the magnetorheological fluid in a suspension state to the transmission main shaft is reduced, and then friction loss of the transmission main shaft when power is transmitting is reduced.

Description

technical field [0001] The invention relates to the technical field of clutch transmission mechanisms, in particular to a transmission coupling shaft clutch mechanism based on magneto-rheological fluid. Background technique [0002] As a common component in mechanical transmission, the clutch mechanism can separate and engage the power in the transmission system at any time, and then effectively control and adjust the power output of the engine or motor. At present, in the prior art, the power Most of the switching uses a multi-plate friction clutch mechanism, but this multi-plate friction clutch mechanism will have wear between the friction plates during engagement, which will cause the gap between the friction plates to become larger, thereby prolonging the power during engagement. The length of time, and due to the wear of the friction plate will produce a large amount of powder, which cannot be cleaned in time and adheres to the friction plate, resulting in the deteriora...

Problems solved by technology

[0004] The present invention provides a transmission-coupling-shaft clutch mechanism based on magnetorheological fluid, which has the advantages of no wear and tear during power separation and combination, sensitive response speed and no frustration, smoothness and smoothness during power transmission. The advantage of high stability solves the problem that in the prior art, multi-plate friction clutch mechanisms are used for power switching, but this multi-plate friction clutch mechanism will wear between the friction plates during engagement, resulting in The gap between the friction plates becomes larger, which prolongs the time when the power is engaged, and due to the wear of the friction plates, a large amount of powder will be generated, which cannot be cleaned in time and adheres to the friction plates, resulting in friction when transmitting power. The torque becomes worse, and it is easy to appear relative slippage in the process of power transmission, which will lead to the phenomenon of frustration in the process of power transmission, and the problem of poor smoothness and stability of power transmission
