Abstract

The invention relates to a leveling method and a leveling device for a hydro-pneumatic suspension of a multi-axle vehicle. The leveling device comprises an oil tank, an oil pump, a public accumulator, wheels and a hydro-pneumatic spring component. According to the leveling device, a suspension of a two-axle or multi-axle vehicle is converted into three-point support through the coupling mode of hydro-pneumatic springs, and the vehicle-mounted platform leveling mode based on three-point control is realized. The leveling device also comprises a control panel, a microprocessor, at least three oil charge and discharge control valves connected with an oil liquid pipeline and electrically connected with the microprocessor, a coupling valve connected with the oil liquid pipeline and electrically connected with the microprocessor, an altitude sensor arranged between a cross arm of each suspension and a vehicle body, and a tilt angle sensor fixedly arranged on the vehicle body, wherein the altitude sensor and the tilt angle sensor are electrically connected with the microprocessor through signal wires, and the microprocessor consists of a solver and a controller.

Description

technical field [0001] The invention relates to an automatic body leveling device for a wheeled vehicle, in particular to an oil-pneumatic suspension system with lifting and leveling functions—a multi-axle vehicle oil-pneumatic suspension leveling device and method. Background technique [0002] As we all know, the normal operation of many vehicle-mounted instruments requires a horizontal working platform, so the vehicle-mounted platform is required to have an automatic leveling function. [0003] At present, most of the vehicle-mounted platforms use rigid outrigger leveling devices. Although the device has a simple structure, high reliability, and easy control of precision, it needs to extend the rigid outriggers during leveling, which takes a long time to level. The uneven load distribution between the rear supporting legs is likely to cause the phenomenon of empty legs and poor stability of the platform. In addition, arranging multiple rigid outriggers on the vehicle bod...
