全地面起重机普遍采用的油气悬挂系统具有良好的减振性能,可使整车行驶时具有很高的行驶平顺性和操纵稳定性,能最大限度地满足行驶需求。本文主要探讨油气悬挂系统刚性闭锁失效的原因及排查方法。1.系统结构和工作原理(1)结构全地面起重机油气悬挂系统分为独立式和连通式2种结构。连通式油气悬挂系统具有较好的抗侧倾性能,从而得到广泛应用。连通式油气悬挂系统主要元件包括4个悬挂缸、2个蓄能器、4
All-terrain crane commonly used oil and gas suspension system has good damping performance, allowing the vehicle traveling with high ride comfort and steering stability, to maximize the travel needs. This paper mainly discusses the reasons for the failure of rigid locking of the oil-gas suspension system and the troubleshooting method. 1. System structure and working principle (1) Structure All-terrain crane oil-gas suspension system is divided into independent and connected two kinds of structures. Connected oil and gas suspension system has good anti-roll performance, which has been widely used. The main components of the connected oil-gas suspension system include 4 suspension cylinders, 2 accumulators,
