Embodiment 1

[0090] refer to Figure 5 , a four-wheel vehicle coupling active torsion-eliminating suspension that uses oil-pneumatic springs as elastic elements, including four oil-pneumatic springs 2 that are respectively arranged on four wheels to support the vehicle body and four springs that connect the wheels and the vehicle body at both ends The stroke sensor 4, the oil pump 5, and the oil storage tank 6 that perceive the height error of its spring 2, the cylinder body of each oil-gas spring 2 are respectively connected with the oil pump 5 and the oil storage tank 6 pipelines through the electromagnetic control valve 1, and also includes a microprocessor (CPU) ) constitutes a central controller 3, each stroke sensor 4 is electrically connected to the input end of the central controller 3, and the electromagnetic control valve 1 controlling each oil-gas spring 2 is electrically connected to the output end of the central controller 3, and the central controller 3 is electrically connect...

Embodiment 2

[0103] refer to Image 6 , a four-wheeled vehicle coupled active anti-torsion suspension that adopts an air spring as an elastic element, as long as embodiment 1 (i.e. Figure 5 The control medium in ) is changed from oil to air, oil pump 5 and oil tank 6 are replaced by air pump 5’ and air storage tank 6’, oil and gas spring 2 is replaced by air spring 2’, and its control system is the same as Figure 5 same.

Embodiment 3

[0105] refer to Figure 7 , a four-wheel vehicle coupled active anti-torsion suspension composed of hydraulic springs as elastic components, as long as the Figure 5 The elastic element oil-gas spring 2 can be changed to a hydraulic spring 2″, and its control system is the same as Figure 5 same.

Abstract

An active mult-wheeled suspending frame for eliminating torsion-vibration is achieved by a central controller, which controls supporting spring according their height signals from sensors arranged on the supporting springs. Some solenoid valves, a power pump and an oil or gas tank are used to actuate those sprnigs according to electric signals come from the central controller, so that torsion-vibration and declination of a vehicle can be eliminated.

Description

technical field [0001] The invention relates to a height-adjustable automobile suspension technology, in particular to a multi-wheel coupling active anti-torsion suspension for automobiles running on uneven roads. Background technique [0002] At present, most air suspensions and oil-pneumatic suspensions are equipped with height control valves to ensure that the suspension height of the car is maintained when the load of the car changes. [0003] The function of the usual suspension height control system is mainly to keep the suspension height of the car from changing with the load and the unevenness of the road surface. figure 1 It is the basic structure of a highly electromagnetic control system for conventional oil and gas spring suspension units. The upper end of the oil-gas spring 2 and the stroke sensor 4 are fixed on the vehicle body, the piston rod of the oil-gas spring and the lower end of the sensor 4 are connected to the wheel, and the cylinder body of the oil-g...
