Problems solved by technology
However, regardless of dynamic adjustment or static adjustment, the existing air spring height adjustment requires the controller to control the gas compressor to compress the air into the air storage tank, and at the same time control the charging and deflation solenoid valve to charge and deflate the air spring, so often It is necessary to start the compressor to compress the air to the air storage tank. The air compressor consumes a lot of energy, and at the same time, the compressor and the air storage tank take up a lot of space

Embodiment Construction
[0017] Such as figure 1 As shown, the air spring KT and the damper ZN in the vehicle suspension are connected in parallel, and are installed between the unsprung mass H2 and the sprung mass H1 of the vehicle. A dynamic vehicle body height adjustment system of the present invention comprises a compression cylinder D0, a height adjustment device E, a push rod F, a height sensor G, an air release solenoid valve C and a controller CO. Among them, the upper end of the cylinder body of the compression cylinder D0 is fixedly connected to the sprung mass H1 of the vehicle, the lower end of the compression cylinder D0 is connected to the height adjustment device E, and the ejector rod F is arranged directly below the height adjustment device E, and the ejector rod F is fixedly connected to the vehicle. On the unsprung mass H2, there is a certain gap between the push rod F and the height adjusting device E.
[0018] The cylinder body of the compression cylinder D0 is an inverted T-shap...

The invention discloses a dynamic vehicle body height adjusting system and method, and relates to vehicle suspensions. The dynamic vehicle body height adjusting system comprises a compression cylinder, a height adjusting device, a jacking rod, a height sensor, a deflation electromagnetic valve and a controller. When the height of a vehicle body needs to be increased, the controller sends a forward rotation electric signal to the height adjusting device, the upper-lower distance between the height adjusting device and the jacking rod becomes small till the lower end face of the height adjusting device touches the upper end face of the jacking rod, so that the height adjusting device moves upwards together with a large piston, compressed air enters an air spring to supplement air for the air spring, and the height of the vehicle body is increased. When the height of the vehicle body needs to be decreased, the controller outputs a reverse rotation signal to the height adjusting device, the upper-lower distance between the height adjusting device and the jacking rod becomes large, meanwhile, the deflation electromagnetic valve is controlled to conduct deflation operation on the air spring, and the height of the vehicle body is decreased. Air inflation and deflation are controlled actively in the vehicle driving process, the comfort, controllability and stability of a vehicle are ensured, energy is saved, and an air compressor and an air storage tank do not need to be additionally arranged.
Description
technical field [0001] The invention relates to the field of air springs in vehicle suspension, in particular to a system capable of adjusting the vehicle body height. Background technique [0002] Air springs are widely used in automobile suspension due to their excellent damping properties and convenient height adjustment. The height adjustment of the vehicle body is realized by adjusting the height of the air spring. Vehicle height adjustment is divided into static vehicle height adjustment and dynamic vehicle height adjustment, wherein static refers to the vehicle height adjustment when the vehicle is parked, and dynamic refers to the vehicle height adjustment during the driving process. However, regardless of dynamic adjustment or static adjustment, the existing air spring height adjustment requires the controller to control the gas compressor to compress the air into the air storage tank, and at the same time control the charging and deflation solenoid valve to charge...
