Trapezoidal inner wall cylindrical coupling based on magnetorheological fluid

Abstract

The invention relates to a trapezoidal inner wall cylindrical coupling based on a magnetorheological fluid, which consists of an input group and an output group, wherein the input group comprises an input shaft, an input end shell, an electromagnetic coil and the like; and the output group comprises an output shaft, a spring, an output end shell and the like. a groove structure at the tail end ofthe input shaft is matched with a convex structure at the tail end of the output shaft; trapezoidal teeth at the outer circumference of the input shaft are matched with trapezoidal grooves at the inner circle side of the output shaft; the matching surfaces are all filled with magnetorheological fluid, and the input end shell and the output end shell are connected and sealed. The coupling providedby the invention is provided with a trapezoidal teeth - trapezoidal grooves structure; the spring is added at the axial direction so as to increase the horizontal vibration isolation effect and reducethe vibration and noise when the coupling works; meanwhile, the coupling has the advantages of simple structure, convenient processing and maintenance, etc. , so the coupling is suitable for non-high-power places and can achieve good vibration isolation effect without precise design and processed components. The coupling provided by the invention solves the problems of vibration and noise generated by mechanical contact the automobile coupling during the process of transmitting force and moment.

Description

technical field [0001] The invention relates to a cylindrical coupling, in particular to a trapezoidal inner wall cylindrical coupling based on magneto-rheological fluid, which can be applied to the connection between two axles of automobiles or between axles and rotating parts to avoid mechanical contact . Background technique [0002] With the development of the automobile industry, higher requirements are placed on the ride comfort of automobiles, and automobile couplings are one of the important factors affecting the NVH performance of chassis transmission. Traditional couplings generally transmit force and torque through hydraulic transmission. Although they can solve the vibration and impact caused by mechanical contact, the transmission efficiency is reduced and the structure is complicated, making maintenance inconvenient. [0003] Magnetorheological fluid is an intelligent material with great development prospects and engineering application value. It is composed o...
