Abstract

The invention discloses a walking device with variable tire pressure, and belongs to the technical field of active vehicle security. The walking device comprises a wireless signal transmission receiving device, a wireless control valve, a wireless control one-way valve, a tire pressure sensor, an air compressor and the like. The walking device is characterized in that a tire is internally partitioned into an inner cavity and an outer cavity through an inner/outer cavity partitioning plate; air of the inner cavity and the outer cavity is subjected to corresponding air exchange through the wireless control valve, the wireless control one-way valve and the air compressor, so that pressure increase and release of the outer cavity can be achieved, and pressure variation of a tire is achieved. The tire needs no air inflation, or even vehicle body posture control of a certain amplitude can be achieved, and the tire pressure can be increased or decreased according to the running situations of a vehicle and the brake and steering intention of a driver, so that the power performance, the brake performance and the security of the vehicle can be improved. The walking device has the advantages that vehicle tire pressure variability, no air inflation and vehicle body posture control of certain amplitude are achieved.

Description

technical field [0001] The invention relates to a walking device with variable tire pressure, which belongs to the technical field of vehicle active safety. Background technique [0002] Ordinary tires are usually equipped with the tire pressure value recommended by the car, and the tire pressure remains unchanged for a long period of time, which means that the contact area between the tire and the ground remains unchanged under the recommended tire pressure. The forces generated by the interaction between the tire and the ground are unchanged. [0003] Most modern cars are equipped with ABS (anti-lock braking system) active safety device, which controls the tire slip rate of the vehicle to maintain the maximum adhesion coefficient with the ground, thereby providing greater braking force, but it cannot be further improved adhesion coefficient. [0004] The tire pressure has a nonlinear relationship with the coefficient of adhesion between the tire and the ground. The lower...
