Electricity generation energy dissipation braking type automobile retarder

Abstract

The invention discloses an electricity generation energy dissipation braking type automobile retarder. The retarder is similar to a common eddy current retarder in profile. The retarder is internally composed of stators, rotors, a stator body, an energy dissipation device arranged outside the retarder and the like. Dual rotor discs of the retarder are circular discs which are both provided with polarity magnets. The stators of the retarder are disc windings. According to the working principle, the rotor discs of the retarder are provided with the permanent magnets, and the rotors are driven by a transmission shaft to rotate to form a rotating magnetic field; coils on the stators are cut through the rotating magnetic field and generate electricity to generate electromotive force, the electromotive force is applied to the energy dissipation device arranged outside the retarder, the inertia kinetic energy is converted into heat energy to be dissipated in the energy dissipation device, the purpose of retarding is achieved, the risk that the rotors of the retarder are overheated can be avoided, and the power of an automobile generator and a storage battery does not need to be increased. The electricity generation energy dissipation braking type automobile retarder can be arranged at the output shaft end of a speed changing device, or between transmission shafts or at the input shaft end of a drive axle.

Description

technical field [0001] The patent of the invention relates to an auxiliary brake of an automobile, that is, a retarder, in particular to a retarder utilizing the principle of energy consumption braking of a generator, which belongs to the field of automobile safety control. Background technique [0002] Automobile retarder is a non-friction auxiliary braking device, which consumes most of the driving kinetic energy before the vehicle brakes, which can effectively improve the safety and continuous braking performance of the vehicle, and reduce the cost of the vehicle [0003] In the middle of the last century, many European countries have promulgated traffic regulations, and the retarder is listed as the standard configuration of the car. In recent years, with the promulgation of relevant laws and regulations in China, automobile retarders have gradually been applied and promoted. At present, eddy current retarders and hydraulic retarders are the two most widely used product...

AI Technical Summary

Problems solved by technology

In short, the above-mentioned retarders have their own advantages and disadvantages, but the common disadvantage is that the huge inertial kinetic energy of the car is finally consumed in the form of heat energy consumption in the rotor of the retarder to achieve the purpose of retarding, and the eddy current retarder is working Huge heat will be generated, and the heat will cause thermal deformation of the rotor and performance degradation
