Abstract

The invention relates to an intelligent adjusting system for the height of a multi-shaft heavy-duty cross-country chassis. The system comprises a suspension height measurement module, a central processor module, a display interaction module, an execution module, an image processing module, a positioning processing module and a mode module. The central processor module is connected with a CAN vehicle body bus to receive vehicle speed information in real time, the image processing module is connected with a driving image system to acquire road surface information, and the positioning processingmodule is connected with a vehicle-mounted BDS and can receive vehicle position information synchronously; the information is sent to the mode module to select a preset chassis height mode, an instruction is sent to the execution module to make the chassis reach a mode set height, the suspension height measurement module transmits the height information to the central processor module in real time, and thus intelligent adjustment of the chassis height is achieved. By means of the system, intelligent adjustment of the ground clearance of the chassis under no load or full load can be achieved, the highway maneuverability, obstacle-crossing driving and railway transport of the chassis are guranateed to improve the maneuverability and the trafficability characteristic, and meanwhile it is avoided that as the center of mass is high, the stability and the driving speed in railway transport cannot be guaranteed.

Description

technical field [0001] The invention relates to the technical field of special off-road vehicles, in particular to a multi-axle heavy-duty off-road chassis height intelligent adjustment system. Background technique [0002] Heavy-duty multi-axle off-road chassis are mostly used in special fields such as aerospace, military, special engineering, etc. It is often necessary to transport equipment by rail to specific areas and the roads are complex and changeable, and the road conditions are bad, in order to meet high mobility and passability. The heavy-duty off-road chassis requires a large-stroke independent oil-pneumatic suspension height adjustment capability to control the ground clearance of the chassis. The large-stroke chassis height adjustment is realized by adjusting the oil-pneumatic spring of the oil-pneumatic suspension. At present, the adjustment of the oil-pneumatic suspension is mainly semi-active control. The height control is realized through the control button...
