Retarder with function of self-generating electric and used for vehicles

Abstract

The invention discloses a retarder used for vehicles. The retarder used for the vehicles comprises a retarder stator assembly, a retarder rotor, a first generator and a second generator, wherein the retarder stator assembly comprises even number of magnetic poles, all the magnetic poles are fixed on a stator disc, the retarder rotor rotates relative to the retarder stator assembly and is used for generating retarding torque, the first generator and the second generator are all fixed on the stator disc of the retarder stator assembly, rotors of the first generator and the second generator are all connected with a rotor belt wheel through a belt, and the rotor belt wheel is fixed with the retarder rotor.

Description

technical field [0001] The invention relates to an automobile component, in particular to an eddy current retarder for vehicles. Background technique [0002] The eddy current retarder is an auxiliary braking device for automobiles. The device is installed between the car drive axle and the gearbox, and realizes non-contact braking through the principle of electromagnetic induction. The eddy current retarder can provide strong braking torque in a fairly wide speed range, thereby avoiding safety hazards such as vehicle deviation, traditional brake failure and tire blowout, while reducing brake pad wear and prolonging brake pad life. Customers bring economic benefits, so they are widely used in motor vehicles, especially large motor vehicles. [0003] Such as figure 1 as shown in figure 1 It is a relatively typical eddy current retarder in the prior art. The eddy current retarder is composed of a rotor 1 , a stator assembly 2 , a rotor adjusting gasket 3 and a support fra...

AI Technical Summary

Problems solved by technology

[0005] The eddy current retarder in the prior art is powered by a battery or a generator. The output current of the generator configured in the existing truck is usually lower than 100 amperes, which needs to be supplemented by the electric energy of the battery. Due to the limitation of the capacity of the battery, The excitation current through the coil is often not enough to generate enough braking torque, and at the same time, it will affect the service life of the battery

Therefore, the eddy current retarder in the prior art is limited by the insufficient excitation current, which affects the application of the eddy current retarder on large and heavy motor vehicles
