Brake device for electric automobile

Abstract

The braking device for the electric automobile comprises a base, a regulation and control box and a connecting block are installed on the top face of the base, a motor is installed in the connecting block, a transmission shaft is fixedly connected to the output end of the motor, and the other end of the transmission shaft extends into the regulation and control box; the extending end of the transmission shaft is fixedly sleeved with a first clamping block, and the other end of the first clamping block is connected with a second clamping block in an embedded mode. Power can be quickly blocked, the braking time is shortened, the braking distance is shortened, the safety coefficient is improved, the problem of device defects is solved, direct limiting and friction of wheels are avoided, the braking device is not prone to abrasion, the service life of the braking device is prolonged, the braking effect is kept, potential safety hazards are avoided, and the safety coefficient is increased. Meanwhile, the second brake mechanism is additionally arranged, so that the situation that no corresponding standby brake mechanism exists after one brake fails is avoided, the space is saved, and the safety coefficient is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle braking, in particular to a braking device for electric vehicles. Background technique [0002] Electric vehicles refer to vehicles powered by on-board power supply and driven by motors that meet the requirements of road traffic safety regulations. Due to their smaller impact on the environment than traditional vehicles, their prospects are widely optimistic, and the braking device of electric vehicles Disc brakes are often the main ones. Under the conditions of high-speed driving or emergency braking, braking will not only rub the brake shoes of the brake, but also generate a lot of harmful dust. [0003] After long-term use of the general braking device on the market, the braking device is seriously worn, which reduces the braking effect and easily leads to the occurrence of potential safety hazards. At the same time, there is no second braking mechanism. After a braking failure, there ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a braking device for electric vehicles to solve the problem that after long-term use of the general braking device proposed in the above background technology, the braking device is severely worn, which reduces the braking effect and easily causes safety hazards At the same time, there is no second brake mechanism. After one brake fails, there is no corresponding backup brake mechanism, the safety factor is low, and the general brake device cannot block the power source. After the brake command is issued, it still It takes time to reduce the power transmission, which prolongs the braking time, thereby increasing the braking distance, which makes it difficult to guarantee personal safety and brings about the problem of device defects
