Abstract

The invention relates to a hydro-pneumatic suspension hydraulic control loop device which serves as a hydraulic control device for reinforcing smoothness of vehicles when the vehicles run on different roads, in particular to a hydro-pneumatic suspension control system for a multi-axle vehicle chassis. The hydro-pneumatic suspension control system comprises four hydro-pneumatic suspensions in different communication relations through fifteen two-position three-way electromagnetic valves; the hydro-pneumatic suspensions can also be used for implementing rigid and flexible transformation. According to the system, the four hydro-pneumatic suspensions can be independent of one another and can also be horizontally connected with one another or longitudinally connected with one another in a cross manner by controlling the fifteen two-position three-way electromagnetic valves, so that the system is capable of enhancing the stability of the vehicles, meeting the requirements of multi-axle engineering vehicles for running and operating on different roads, ensuring the smoothness and the stability of the engineering vehicles during running and operating, avoiding the overturn accident and effectively improving the operation efficiency.

Description

technical field [0001] The patent of the present invention relates to a hydraulic control circuit device of an oil-pneumatic suspension, which is a hydraulic control device used to enhance the ride comfort of a vehicle when driving on different road surfaces, specifically an oil-pneumatic suspension control system for a multi-axle vehicle chassis . Background technique [0002] Due to the superior nonlinear elastic characteristics and vibration damping performance of oil-pneumatic suspension, it has been widely used in engineering vehicles and military vehicles. The existing oil-pneumatic suspension system has two connection methods: independent type and interconnected type. Due to the diversification of the road surface of engineering vehicles, when working on ordinary roads, the independent oil-pneumatic suspension system and the interconnected oil-pneumatic suspension system have similar vibration reduction effects, and both can meet the vibration reduction requirements o...
