摘　　要：转向随动器用于传递转向器的输出力矩,控制多轴转向底盘第二转向桥及其他转向桥转向,并提供助力。转向随动器是公司的重点产品,在运输型底盘上大量应用,随着承载要求的提高,对于新研发的重载型产品,需要进行承载能力的可靠性试验,确保产品质量满足客户要求。该文通过对转向随动器的结构及工作原理分析,设计了一种承载能力可靠性试验方法,利用液压系统控制转向随动器输出力,利用第二件转向随动器被动加载,通过程序监测液压系统的压力及被动加载压力,满足了新产品的可靠性测试需求。The steering follower is used to transmit the output torque of the steering gear, control the steering of the second steering axle of the multi axle steering chassis and other steering axles, and provide power. The steering follower is a key product of the company and is widely used in the transportation chassis. With the improvement of the bearing requirements, the reliability test of the bearing capacity needs to be carried out for the newly developed heavy-duty products to ensure that the product quality meets the requirements of customers. Through the analysis of the structure and working principle of the steering follower, this paper designs a reliability test method of bearing capacity. The hydraulic system is used to control the output force of the steering follower, the second steering follower is used for passive loading, and the pressure and passive loading pressure of the hydraulic system are monitored through the program, which meets the reliability test requirements of new products.
