Problems solved by technology

[0005] The eddy current retarder in the prior art is powered by 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, through the coil Exciting current is often insufficient to generate sufficient braking torque
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

Abstract

A self-generating retarder comprises: a stator assembly (2), comprising at least one magnetic pole, the magnetic poles being all fixed on a support (4); a rotor (1), rotating with respect to the stator assembly (2); and at least one generating device (200), located in the stator assembly (2). The self-generating retarder provided by the present invention is applicable to kinds mobile tools, and overcomes the defect of insufficient braking torque of the retarder incurred by the insufficient current when the retarder is used in large or ultra-large transport.

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 in the middle of the transmission shaft between the automobile gearbox and the drive axle, 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...
