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), a speed increasing device, an oil sealing device, a stator (13) and an excitation coil (14). The hub (4) and the rear of the automobile The bridge shaft (1) is connected, the speed increasing device is connected with the hub (4), the oil sealing device is connected with the speed increasing device, and the stator (13) is fixed on the On the rear axle shaft (1), the stator (13) is provided with an inner slot, and the excitation coil (14) is wound in the inner slot of the stator (13). The invention transforms the automobile brake drum into a ring gear used to form a speed-increasing mechanism. The structure is simple, and it is beneficial to improve the braking torque and braking power of the retarder; the rotor is light in weight and small in moment of inertia; the stator is directly fixed on the rear On the bridge shaft, the winding of the excitation coil is simple.

Description

Technical field [0001] The invention relates to a wheel hub type electromagnetic liquid-cooled retarder, which generates eddy current braking torque by cutting the magnetic induction line motion of a rotating and non-contact metal arc surface, and particularly relates to a kind of cooling by circulating water and installed on the rear axle of an automobile A hub type electromagnetic liquid-cooled retarder with a speed increasing mechanism on the shaft belongs to the field of automobile braking. Background technique [0002] Vehicle retarder is an auxiliary braking device for vehicles. The existing retarder is generally installed on the transmission shaft of the automobile transmission system to control the braking and deceleration of the entire axle. The braking torque generated by the retarder first acts on the drive shaft of the car, and then is distributed to the left and right driving wheels, thereby slowing the entire car. For vehicles with no rear-end power devices, such ...
