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

The invention belongs to the field of automobile braking energy recycling, and particularly relates to a braking energy recycling system based on a power generation form. The braking energy recycling system comprises a brake disc, a friction wheel, a power generator, first guide rails, a conical structure, friction wheel reset springs and the like; the friction wheel is installed on a brake pad located on one side, when braking is conducted, the distance between the brake pads and the brake disc is gradually decreased, the friction wheel makes contact with the brake disc of a wheel first, rolling friction is generated between the friction wheel and the brake disc, and the friction wheel rotates to drive the power generator to generate power; the guide rails and the friction wheel reset springs are in such a design that relative motion between the brake pads and the friction wheel is allowed, and it is guaranteed that the motion does not generate interference in the braking process; the variable transmission ratio of the conical structure is in such a design that the rotating resistance of the friction wheel is increased when the braking degree is increased and the brake pads do not make contact with the brake disc, and then the requirement on increasing of the braking degree is met. According to the braking energy recycling system based on the power generation form, the braking energy is extracted through the friction wheel and variable transmission ratio transmission and can be effectively extracted, energy recycling is achieved, and a certain innovativeness and practicability are achieved.
Description
Technical field [0001] The invention belongs to the field of automobile braking energy recovery, in particular to a braking energy recovery system based on power generation. 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 brakin...
