Abstract

The invention relates to a double-stator electromagnetic liquid-cooled retarder. The double-stator electromagnetic liquid-cooled retarder comprises a rotor arm, a rotor, an inner stator, an outer stator, a retarder support and a coil, wherein the rotor arm is connected with a transmission shaft of an automobile through keys; the rotor is connected with the transmission shaft through the rotor arm, moves together with the transmission shaft and is located between the inner stator and the outer stator; the inner stator and the outer stator are both connected with the retarder support through screws; the retarder support is connected with the transmission shaft; the coil is wound on the inner stator; the inner stator, the outer stator and the coil are all stationary parts. According to the retarder, the mass of the rotor is small; the structure is compact; the liquid-cooled heat dissipation mode is adopted; the inner stator is provided with an inner water channel and the outer stator is provided with an outer water channel, so that the radiating area of a vortex layer is increased to facilitate heat dissipation more; the stability of the braking torque can be continually kept; high safety and reliability are achieved.

Description

technical field [0001] The invention relates to an electromagnetic liquid-cooled retarder with a double-stator structure. The eddy current braking torque is generated by cutting the magnetic induction line movement of the rotating and non-contact metal arc surface, and especially relates to a cyclic braking system using the principle of eddy current braking. Water-cooled double-stator electromagnetic liquid-cooled retarder. Background technique [0002] Most of the existing eddy current retarders have multiple sets of coils, and the coils are generally evenly distributed on the circumference, and pole shoes are provided at both ends of the coils; the retarder structure has a brush structure, and the heat generated is on the rotor. The cooling fins on the rotor radiate into the air. Air cooling has low heat dissipation efficiency. Moreover, the mass and moment of inertia of the retarder rotor are large, which has a great influence on the transmission system of the car. Co...
