Problems solved by technology

[0005] In view of the above-mentioned deficiencies existing in the prior art, the purpose of the present invention is to solve the problem that magnetorheological fluid has limited transmission torque, its performance decreases with temperature rise, its stability is poor, it cannot automatically and adaptively transmit torque according to the rotational speed, and its transmission efficiency is reduced. And cause the problem of energy waste, provide an electrothermal extrusion disc magneto-rheological and electromagnetic bearing friction combined transmission device, which can reduce the influence of high temperature on the magnetorheological fluid, and at the same time, the extrusion force generated by the shape memory alloy spring Make the magnetorheological fluid produce extrusion strengthening effect, effectively improve the transmission performance of the transmission device, and ensure the stability of torque transmission; and, the heat generated by the excitation coil is transmitted to the shape memory alloy spring, through the temperature shape memory effect of the shape memory alloy Generate extrusion force to act on the outside, so as to fully convert and utilize heat energy and reduce energy waste

Abstract

The invention discloses an electric heating extrusion disc magneto-rheological and electromagnetic bearing bush friction combined transmission device. The electric heating extrusion disc magneto-rheological and electromagnetic bearing bush friction combined transmission device comprises a driving shaft, a driven shaft and a transmission shell, wherein the part, located in a driven shell, of the driving shaft is expanded to form a transmission section; two armature tiles are symmetrically arranged on the transmission section, and a guide column and a compression shape memory alloy spring are arranged in the middle of the inner side of each armature tile; a liquid containing groove is formed in the outer side of each armature ring, and each liquid containing groove is filled with magnetorheological fluid; extrusion discs are correspondingly arranged between two ends of the transmission section and a left end cover and between two ends of the transmission section and a right end cover, and the guide rods and the extrusion shape memory alloy springs are arranged at one sides, close to the transmission section, of the extrusion discs; a gap between the extrusion disc close to the left end cover and the left end cover and a gap between the extrusion disc close to the right end cover and the right end cover are also filled with magnetorheological fluid. According to the electric heating extrusion disc magneto-rheological and electromagnetic bearing bush friction combined transmission device, the influence of temperature on the magnetorheological fluid can be reduced, the transmission performance of the transmission device is improved, and the stability of torque transmission is ensured; and heat energy is fully converted and utilized, so that energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to an electrothermal extrusion disk magnetorheological and electromagnetic bearing bush friction combined transmission device. Background technique [0002] As a solid-liquid two-phase intelligent material whose shape and performance are constrained and controlled by an external magnetic field, magnetorheological fluid is a special non-colloidal suspension formed by micron-sized magnetic particles evenly distributed in base liquid and surfactant. Its excellent performance is manifested in the fact that under the action of an external magnetic field, the magnetorheological fluid completes the reversible transformation from liquid to viscoplastic in milliseconds. During the increase of magnetic induction, the apparent viscosity of these fluids can show several orders of magnitude changes, have a certain shear yield strength, and can be continuously controlled by the externa...
