Braking power generation mechanism based on hydraulic transmission

Abstract

The invention belongs to the field of automobile braking energy recycling, and particularly relates to a braking power generation mechanism based on hydraulic transmission. The braking power generation mechanism based on hydraulic transmission comprises a brake disk, a brake disk protrusion, brake pad supports, hydraulic columns, a hydraulic cylinder, a piston, a hydraulic motor and a power generator. The brake pad supports are installed on a brake mechanism support. When the brake disk rotates, at the early stage of the braking process, a brake pad gets close to the brake disk gradually, an ejecting block firstly makes contact with the protrusion and is matched with the protrusion, the ejecting block linearly reciprocates in the direction of a cylindrical guide rail, the piston is driven to reciprocate through cooperation so that hydraulic oil can be driven to flow in the hydraulic motor in a reciprocating manner, and therefore the power generator can be driven to generate power; and at the later stage of braking, the brake pad starts to make contact with the brake disk, large friction force is generated, and wheels are braked forcibly. Due to the cooperation of the ejecting block and the protrusion, braking energy is converted into reciprocating movement, and therefore the hydraulic oil is driven to flow in the reciprocating manner, the power generator is driven to generate power, the braking energy is 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 hydraulic transmission. 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 effec...

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,
