Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] Such as figure 1 The brake friction power generation system on the electric vehicle shown includes a brake disc 1 that rotates with the wheel and a brake pad 2 fixed on the brake disc. Two conical pads are placed symmetrically on both sides of the brake disc plane. There is a gap between the wheel 3, the idler wheel 3 and the brake pad 2 in the non-braking state. In the braking state, the two idler wheels are in close contact with the brake pad 2 to generate friction; the two idler wheels are respectively connected by The shaft 5 is connected to the toothed cone 6, and the toothed toothed cone 6 meshes with the generator rotor 8. The left and right two toothed toothed cones and the two meshing surfaces 7 of the generator rotor 8 exist; , when force is applied to the left and right sides of the rollers, so that the two rollers contact the...

Abstract

The invention relates to a brake friction force power generating system on an electric vehicle. The brake friction force power generating system comprises a brake disc and a brake plate, wherein the brake disc rotates together with wheels; the brake plate is fixed on the brake disc; two conical pressing wheels are symmetrically arranged on two surfaces of a plane of the brake disc; a gap exists between the pressing wheels and the brake disc in a non-brake state; under the brake state, the two pressing wheels are in tight contact with the brake plate to generate friction force vigorously in a pincer manner; the two pressing wheels are connected with tooth cones through connection shafts separately; two tooth cones are meshed with a generator rotor; mating surfaces are arranged between the left tooth cone and the generator rotor and between the right tooth cone and the generator rotor; a rotating shaft is arranged in one end, connected with the tooth cone, of each connection shaft; the pressing wheels, the connection shafts and the tooth cones rotate around the rotating shaft; and the left and right pressing wheels transmit brake friction torque to the generator rotor through the left and right tooth cones to control the braking force, thereby changing the generating capacity of the generator. The tooth cones coaxial with the pressing wheels drive the generator rotor to generate electricity in a rotating manner, the braking force is high and the generated power is high.

Description

technical field [0001] The present invention relates to the technical field of brake friction power generation of vehicles, in particular to the brake friction power generation system on electric vehicles. Background technique [0002] Braking friction power generation is to convert the braking friction into the electromagnetic force of the generator for power generation, and convert the braking energy into electrical energy. The vehicle speed is controlled by controlling the magnitude of the braking friction force, which is related to the positive pressure on the friction surface; when the braking friction force is transmitted to the generator rotor, the braking friction force is proportional to the generator torque. [0003] Braking power = braking friction * running speed. [0004] Braking friction is related to factors such as load, slope, and speed decrement. [0005] For an electric vehicle, assuming that the required braking friction force is 2000 Newtons and the ve...
