By the adoption of the system, force is acquired from rotation of an axle in the automobile braking process, the sliding vane type air compression device installed in the position of a brake disc is driven, air compression energy storage is conducted, power is adjusted and controlled by adjusting the initial pressure of air before the air is compressed, high-intensity air compression is achieved, and the large counter torque is output to stop an automobile from moving forwards continuously. By the adoption of the automobile air rotary compression energy storage type braking system, energy can be recycled and stored immediately under the common braking condition, braking operation is conducted on the brake disc through small-size high-intensity rotary air compression design, the system accords with a traditional braking operation habit, and the safety performance and the economic performance of the air rotary compression energy storage type braking system are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and relates to an automobile air rotary compression energy storage brake system. Background technique [0002] At present, many automobiles and passenger cars use pneumatic brakes. The advantages of air brake are large braking torque, short pedal stroke, easy operation and reliable use. The function of the air compressor next to the car engine is to generate compressed air, which is the power source. The air compressor is driven by the power of the engine, and the compressed gas makes the wheels brake. The driver only needs to control the stroke of the pedal according to different braking intensity requirements, release different degrees of compressed air, and then adjust the gas pressure to obtain the required braking force. However, the disadvantage of such a system is that it consumes the power of the engine. On the one hand, it inevitably dissipates energy in frictional heat, wh...

Problems solved by technology

However, the disadvantage of such a system is that it consumes the power of the engine. On the one hand, the energy is inevitably dissipated on frictional heat, which consumes the brake pads. On the other hand, the high-pressure gas cannot be recovered and stored in the gas storage tank after braking. , waste and hot gases are discharged into the atmosphere, resulting in energy loss

But the weak point of this scheme is that the compression mechanism position setting is unreasonable, can not brake effectively, can hinder the work of speed changer, and can reduce the service life of drive shaft; Complexity can limit the design of the car body

The structure of this scheme is relatively clear and simple. However, the energy storage function has a slow response and is limited to long-term taxiing and other working conditions where the braking force demand is not large. Overall, the economic performance is poor.
