Braking power generating mechanism based on air compression

Abstract

The invention belongs to the field of automobile braking energy recycling, and particularly relates to a braking power generating mechanism based on air compression. The braking power generating mechanism comprises a brake disc, brake disc protrusions, a brake mechanism support, a brake energy mechanical conversion mechanism, brake plate supports, hydraulic columns, a power generator, an air motor, compression cylinders, an air tank and pistons. The brake plate supports are arranged on the brake mechanism support. When the brake disc rotates, in the initial stage of the brake process, brake plates are gradually close to the brake disc, an ejector block is in contact matched with the protrusions firstly, the ejector block linearly moves in a reciprocating manner in the direction of a cylinder guide rail, the pistons are driven to reciprocate through cooperation, and accordingly the air motor is driven to drive the power generator to generate power. In the later braking stage, the brake plates start to make contact with the brake disc, larger friction force is generated, and wheels are forcefully braked. By means of cooperation of the ejector block and the protrusions, braking energy is converted into reciprocating movement, the air motor is driven to drive the power generator to generate power accordingly, the brake energy can be effectively utilized, and the energy saving effect of an automobile is improved.

Description

Technical field [0001] The invention belongs to the field of automobile braking energy recovery, and in particular relates to a braking power generation mechanism based on air compression. Background technique [0002] Since the beginning of the 21st century, energy and the environment have increasingly affected human life and social development. Energy-saving and emission-reduction technologies for transportation vehicles are becoming increasingly prominent, vehicle energy recovery technology has received full attention, and braking energy recovery systems have been widely used in electric vehicles and hybrid vehicles. [0003] At present, the basic principle of braking energy recovery for vehicles with a braking energy recovery system is: during the braking process, the electric motor is used to generate electricity and the electric energy is stored in the power battery to realize the recovery and utilization of the braking energy. At this stage, the effectiveness of the braking...

AI Technical Summary

Problems solved by technology

At this stage, the effectiveness of the braking energy recovery system is insufficient, especially when the braking demand is large, the braking torque generated by the motor cannot meet the braking force demand of the whole vehicle. At this time, mechanical braking is required to intervene and provide additional braking Torque, resulting in waste of heat energy generated by mechanical braking

In addition, due to the limitation of the charging and discharging times of the power battery, frequent braking charging and discharging will also have a certain impact on the service life of the power battery, which will correspondingly reduce the service life of the power battery.

In addition, because the existing braking energy recovery system needs to use the power battery, because the power battery is mostly used in the hybrid system and the pure electric vehicle, and the traditional vehicle cannot use the existing braking energy recovery system to recover the braking energy
