Abstract

The invention discloses a current vortex retarder comprising a stator and a rotor, wherein the stator is fixed on a stator shaft sleeve, the rotor is fixed on a rotor shaft sleeve, and the stator shaft sleeve and the rotor shaft sleeve are connected through rolling bearings. The retarder is characterized by capability of effectively overcoming defects of the technology of the prior art, lowered cost, and ease of installation.

Description

technical field [0001] The invention relates to a component used for transportation equipment, in particular to an eddy current retarder and transportation equipment using the eddy current retarder. 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 a strong braking torque in a fairly wide speed range, thereby avoiding safety hazards such as vehicle deviation, traditional brake failure and tire blowout, so it is widely used in motor vehicles, especially large machines on the train. Such as figure 1 As shown in , the eddy current retarder is composed of rotor 1, stator 2, rotor adjusting gasket 3 and support frame 4. The stator 2 is usually composed of an even number of magnetic poles arranged in a certain positional relationship. ...
