Abstract

The invention provides a stator and coil integrated liquid cooling electric eddy current speed retarder, which comprises a left stator and a right stator, wherein the left stator and the right statorare fixedly connected; then, a magnetic separation welding plate is arranged at the outside of the left stator and the right stator; a water inlet and a water outlet are formed in the outer side of the left stator; a cavity structure is formed inside the left stator and the right stator; a water passage is distributed in the cavity; a coil part is fixed in the cavity and a wire is led out in the side surface; the coil part separates the inside of the whole cavity into two circulation flow passages; the rotor part comprises a rotor tooth and a rotor support frame; the rotor support frame is arranged at one side of the rotor tooth; the rotor support frame performs coaxial rotation relative to the left stator; a gap is formed between the rotor support frame and the right stator; gaps are formed both between the rotor tooth and the left stator and between the rotor tooth and the right stator; the rotor support frame is connected to a rotating shaft through a magnetism isolation flange. Thestator and the coil integrated liquid cooling electric eddy current speed retarder has the advantages that the structure is simple; the processing is convenient; the cost is reduced; the magnetic path is simplified and the braking effect is improved.

Description

technical field [0001] The invention belongs to the field of non-contact automobile auxiliary braking, in particular to a stator and coil integrated liquid-cooled eddy current retarder. Background technique [0002] With the rapid development of the automobile industry, the acceleration performance and loading performance of automobiles have been continuously improved, which has brought great convenience to the traffic and transportation industry. At the same time, the requirements for the braking performance of automobiles are getting higher and higher. At present, friction braking is still the main braking form of automobiles. In the case of long-term or frequent braking, rapid braking will generate a lot of heat, and the long-term accumulated wear will be very serious, which seriously threatens its braking performance and braking life. In order to ensure the safety of automobile braking, automobile auxiliary braking device is essential. [0003] The eddy current retarde...
