Problems solved by technology

For vehicles without power devices at the rear end, such as full trailers or semi-trailers, due to the large inertia after the trailer is partially loaded with goods, if the retarder is only installed on the tractor part of the vehicle, there is still a relatively large driving safety hazard.

Abstract

The invention relates to a hub-type electromagnetic liquid cooling retarder which comprises a hub (4), an accelerating device, an oil liquid sealing device, a stator (13) and an excitation coil (14), wherein the hub (4) is connected with the rear axle (1) of an automobile; the accelerating device is connected with the hub (4); the oil liquid sealing device is connected with the accelerating device; the stator (13) is fixed on the rear axle (1) through a bolt; an internal groove is formed in the stator (13); the excitation coil (14) is coiled in the internal groove of the stator (13). The hub-type electromagnetic liquid cooling retarder has the advantages that an automobile brake drum is reformed into a gear ring serving as a part of an accelerating mechanism; the structure is simple; the braking torque and the braking power of the retarder can be improved; a rotor is light, so that the rotary inertia is low; the stator is directly fixed on the rear axle, so that the coiling of the excitation coil is simple.

Description

technical field [0001] The invention relates to a hub-type electromagnetic liquid-cooled retarder, which generates eddy current braking torque by cutting the magnetic induction line movement of a rotating and non-contact metal arc surface, especially relates to a cooling device that is cooled by circulating water and installed on the rear axle of an automobile. The utility model relates to a wheel-hub type electromagnetic liquid-cooled retarder with a speed-increasing mechanism on the shaft, which belongs to the field of automobile braking. Background technique [0002] Vehicle retarder is a kind of vehicle auxiliary braking device. The existing retarder is generally installed on the transmission shaft of the automobile transmission system to control the braking and deceleration of the entire vehicle axle. The braking torque generated by the retarder first acts on the drive shaft of the car, and then is distributed to the driving wheels on the left and right sides, so that ...
