Braking power generation mechanism based on cooperation of balls

Abstract

The invention belongs to the field of automobile braking energy recycling and particularly relates to a braking power generation mechanism based on the cooperation of balls. The braking power generation mechanism comprises a brake disc, brake disc protrusions, a brake mechanism support, a mechanical braking energy converting mechanism, brake block supports, hydraulic columns, a lead screw, a ball revolute pair, a gear and a power generator, wherein the brake block supports are installed on the brake mechanism support. When the brake disc rotates in the initial stage of braking, brake blocks get close to the brake disc gradually, an ejector block is in contact fit with the protrusions firstly, the ejector block conducts reciprocating rectilinear movement in the direction of a cylindrical guide rail, the ball revolute pair is driven to rotate in a reciprocating mode through cooperation, and accordingly the power generator is driven to generate powder; in the later stage of braking, the brake blocks start to make contact with the brake disc and generate large friction force, and strong braking is conducted on automobile wheels. According to the braking power generation mechanism, the braking energy is converted into reciprocating movement through the cooperation of the ejector block and the protrusions, so that the ball revolute pair is driven to drive the power generator to generate power, the braking energy can be utilized effectively, 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, in particular to a braking power generation mechanism based on ball cooperation. Background technique [0002] Since the beginning of the 21st century, energy and the environment have had an increasing impact on human life and social development. Energy-saving and emission-reduction technologies for transportation tools are becoming more and more prominent, energy recovery technology for vehicles has been given full attention, and braking energy recovery systems are widely used in electric vehicles and hybrid vehicles. [0003] At present, the basic principle of braking energy recovery for vehicles with braking energy recovery system is: during the braking process, the motor is used to generate electricity, and at the same time, the electric energy is stored in the power battery to realize the recovery and utilization of braking energy. At this stage, the effectiveness of the br...

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,
