The invention relates to an interconnected hydraulic air suspension for an oil field truck and a control system of the interconnected hydraulic air suspension. The interconnected hydraulic air suspension consists of a hydraulic air suspension and a suspension height control system, the duplex-bridge suspension system is formed by combining two single-bridge suspensions, and the two single-bridge suspensions are the same in structure and arrangement mode. The single-axle suspension system is composed of a hydraulic oil cylinder, an oil cylinder support, a guide arm, a guide arm support, a transverse thrust rod, a transverse thrust rod support and the like. In order to ensure the running stability of the vehicle, two-stage pressure energy accumulators are arranged on the left side and the right side of the duplex bridge, and the energy accumulators connect the left (right) middle oil cylinder and the left (right) rear oil cylinder through oil pipes respectively to provide rigidity and damping functions for the system. In order to facilitate goods loading and unloading and maintenance of a user, a suspension height control system is matched based on the suspension system, and manual and automatic adjustment is supported. The oil tanker has the characteristics of simplified structure, flexible arrangement, large ground clearance, high bearing capacity, high roll stiffness, quick system response and the like, and meets the requirements of the oil tanker in a severe and complicated transportation environment.
本发明涉及一种油田车用互联式液力空气悬架及其控制系统,由液力空气悬架及悬架高度控制系统组成。双联桥悬架系统由两个单桥悬架组合成,两个单桥悬架结构、布置方式相同。单桥悬架系统由液压油缸、油缸支架、导向臂、导向臂支架、横向推力杆、横向推力杆支架等组成。为保证车辆行驶稳定性,在双联桥左、右两侧布置一个两级压力蓄能器,蓄能器通过油管将左(右)中油缸、左(右)后油缸分别连接起来,为系统提供刚度和阻尼功能。为方便用户装卸货物和维修保养,基于该悬架系统,匹配有悬架高度控制系统,支持手动和自动调节。具有结构简化,布置灵活,离地间隙大,承载能力强、侧倾刚度大、系统响应快等特点,满足运油车恶劣复杂运输环境需求。
