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 discloses an eddy current retarder mounted on a vehicle transmission shaft. The eddy current retarder is characterized by comprising a stator, a rotor, a rotor shaft sleeve and a magnetic conducting ring, wherein the stator is used for generating a magnetic field, and is fixed on a stator shaft sleeve; the rotor is only positioned at one side of the stator, and is fixed on the rotor shaft sleeve; the rotor shaft sleeve is connected with the vehicle transmission shaft; and the magnetic conducting ring is positioned at the other side of the stator, and is used for guiding the magnetic field.

Description

technical field [0001] The invention relates to a component used for transportation equipment, in particular to an eddy current retarder installed on a vehicle transmission shaft. 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 rela...
