The invention relates to a new energy vehicle air brake energy feedback piston type blocking control valve. The blocking control valve comprises a brake pedal brake valve, and the brake pedal brake valve is connected to an air brake pipeline connected to a service brake system; the brake pedal brake valve is also connected with a brake light switch and a brake analog sensor; the brake light switch, the brake analog sensor and a throttle analog sensor are all connected to a vehicle control unit (VCU), the VCU controls a motor to perform generating slow braking through a motor control unit (MCU), and the energy is recovered to a power battery; the blocking control valve is arranged between the brake pedal brake valve and the air brake pipeline, and the blocking control valve is also connected to the VCU. Two identical blocking control valves are serially connected in two ways of the air brake pipeline output by the brake pedal brake valve, the kinetic energy and / or the potential energy of a vehicle is converted into the electric energy of the power battery under multiple working conditions and stored to save energy.
Description
technical field [0001] The invention relates to a new energy vehicle, in particular to a new energy vehicle air pressure braking energy feedback piston type blocking control valve. Background technique [0002] At present, new energy vehicles generally have energy recovery design. Due to the requirements of braking regulations (such as GB 7258, GB 12676, etc.), when the driver steps on the pedal, most of the vehicle braking systems will work synchronously, and the driving static friction material and the high-speed rotating friction material of the wheel will rub against each other to generate braking force, forcing The vehicle stops. During this period, a large amount of kinetic energy or potential energy of the vehicle is converted into useless heat energy, which is wasted; when going down a long slope, these heat energy will affect the thermal stability of the vehicle brake and cause the brake thermal decay. [0003] figure 1 It is a partial schematic diagram of the ex...
