Embodiment 1

[0039] Such as Figures 1 to 3 As shown, the braking energy recovery system includes a rotor 10, a stator 20, a controller and an energy storage device. The rotor 10 is fixedly installed on the flange fork of the input shaft of the final reducer 40, and the stator 20 is fixedly installed on the main On the front end cover of the reducer 40, the input end of the energy storage device is electrically connected to the coil 30 of the stator 20, and the controller controls the path and disconnection of the electrical connection between the energy storage device and the coil 30 of the stator 20 . Wherein, both the stator 20 and the rotor 10 are made of laminated and pressed silicon steel sheets.

[0040] The brake energy recovery system also includes a first end cover 22 and a second end cover 23, the first end cover 22 and the second end cover 23 clamp the stator 20, and the first end cover 22 is fixedly installed On the front end cover of the final reducer 40 .

[0041] The bra...

Embodiment 2

[0061] The difference between this embodiment and Embodiment 1 is that

[0062] Such as Figure 4 As shown, the rotor 10 is fixedly installed on the flange fork of the output shaft of the transmission 50, the first end cover 22 and the second end cover 23 clamp the stator 20, and the second end cover 23 is fixed On the rear end cover of the transmission 50 .

[0063] The advantage of this embodiment:

[0064] The installation positions of the rotor 10 and the stator 20 are increased to adapt to more car models.

[0065] The rest of the structures and principles are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a braking energy recovery system and a using method thereof. The braking energy recovery system comprises a rotor, a stator, a controller and an energy storage device, whereineither the rotor is fixedly mounted on a flange yoke of an input shaft of a main reducer and the stator is fixedly mounted on a front end cover of the main reducer, or the rotor is fixedly mounted ona flange yoke of an output shaft of a transmission and the stator is fixedly mounted on a rear end cover of the transmission; an input end of the energy storage device is electrically connected to coils of the rotor; and the controller controls the circuit connection and circuit opening of the electrical connection between the energy storage device and the coils of the rotor. The braking energy ofa car is recovered through the action of the rotor and the stator.

Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to a braking energy recovery system and a using method thereof. Background technique [0002] With the rapid development of the automobile industry and the sharp increase in car ownership, the pressure on energy and the environment caused by automobiles is increasing, which has become a "major event" of common concern to all countries. During the braking process of a car, a large amount of kinetic energy can only be converted into heat energy and dissipated into the atmosphere through the friction of the brake, which not only wastes precious energy, but also causes premature wear of the car brake, increases the cost of the car, and is To a certain extent, dust pollution has been produced to the environment. Relevant studies have shown that under urban driving conditions, the braking deceleration or parking is frequent, and the braking energy accounts for about 30-50% of the...
