Problems solved by technology

When the retarder is working, the front and rear rotors 1 rotate at the same time. On some small vehicles, the rigidity of the drive shaft is low. Due to the large moment of inertia of the retarder rotor, the moment of inertia between the vehicle drive shaft and the retarder When the matching is not correct, the transmission system will undergo torsional vibration, and the resulting noise will affect the comfort of the vehicle and the service life of the transmission system components

Abstract

The invention provides an eddy current retarder. The eddy current retarder comprises a stator, a rotor and a vibration damper, wherein the stator is used for generating a magnetic field; the rotor is used for cutting the magnetic field to generate a braking torque; the rotor is only positioned at one side of the stator; the vibration damper is positioned at the other side of the stator; both the rotor and the vibration damper are connected with a vehicle transmission shaft, and are in circular motion relative to the stator.

Description

technical field [0001] The invention relates to a component used for transportation equipment, in particular to an eddy current retarder. Background technique [0002] The eddy current retarder is an auxiliary braking device for automobiles. The device is installed on the transmission shaft between the vehicle 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. Each pole is made of a coil wou...
