Description

technical field [0001] The invention relates to an electromagnetic liquid-cooled retarder with double stators and double coils. The utility model belongs to the field of non-contact automobile braking. Background technique [0002] The retarder is a safety auxiliary device for driving brakes, which applies the braking force to the transmission parts of the vehicle to consume harmful energy and reduce the driving speed of the vehicle. The basic principle of the eddy current retarder is: when the metal plane or arc is cutting the magnetic induction line, the air gap flux density changes periodically with the rotation of the rotor, and an eddy current potential will be generated on the surface of the stator and within a certain depth range. , and generate eddy current, and the magnetic field formed by the eddy current interacts with the air gap magnetic field to generate braking torque. The kinetic energy of the vehicle is converted into heat energy and consumed through the m...

AI Technical Summary

Problems solved by technology

[0003] The existing eddy current retarder structure basically adopts air-cooled structure, which makes it difficult to dissipate heat and cause serious thermal degradation

The axial size of the existing electromagnetic liquid-cooled retarder is too large. When the axial installation size is required, the smaller axial size becomes the bottleneck restricting the performance of the electromagnetic retarder, which greatly reduces the braking performance of the electromagnetic retarder. torque
