Electromagnetic liquid cooling decelerator adopting outer rotor structure

Abstract

The invention relates to an electromagnetic liquid cooling decelerator adopting an outer rotor structure. The electromagnetic liquid cooling decelerator comprises a rotor arm, a rotor, a stator, a decelerator bracket and a coil, wherein the rotor arm is connected with a transmission shaft of an automobile through a key; the rotor is connected with the rotor arm, is connected with the transmission shaft through the rotor arm, moves together with the transmission shaft, and is a tooth-shaped rotating disc; more than two salient poles are arranged on the inner wall of the rotor; the stator is connected with the decelerator bracket; the coil is directly wound on the stator; the coil and the stator are static components. The electromagnetic liquid cooling decelerator has the characteristics that non-contact braking is adopted; the braking performance of the automobile is improved effectively; the structure is compact; the mass is lightened; the mounting is simple and convenient; maintenance is reduced; environmental pollution is avoided; pole-free adjustment of braking torque can be realized; the work efficiency is improved; requirements of the automobile can be met better.

Description

technical field [0001] The invention relates to an electromagnetic liquid-cooled retarder. According to the principle of eddy current, the high-speed rotating rotor cuts the motion of the magnetic induction line generated by the coil to generate braking torque to perform auxiliary braking on the car, especially an outer rotor structure. The invention relates to a liquid-cooled retarder with a salient pole structure cooled by circulating liquid, which belongs to the field of automobile braking. Background technique [0002] The eddy current retarder disclosed in the invention patent (patent application number CN201210061808.1) entitled "A liquid-cooled eddy current retarder with a salient pole structure" adopts a salient pole structure, but the salient pole rotor The moment of inertia is very large, which may have a certain impact on the transmission system of the car; the structure of the retarder requires a coil support, and there is a certain degree of difficulty in proces...
