中央回转接头作为工程车辆连接上下车液压系统的关键部件,其性能的优劣直接影响了主机的油路供应状态,因此对其性能的参数检测就显得尤为重要。而目前国内已开发出的可对其进行参数检测的性能试验装置还较为少见,本文将介绍一种中央回转接头性能试验系统的研究思路,并给出了相应的回转机构及液压系统的设计参考方案。 As a key component of the hydraulic system for getting on and off the vehicle, the central swivel joint has a direct impact on the oil supply state of the host due to its performance. Therefore, it is very important to measure the parameters of its performance. At present, the performance testing device that has been developed to test its parameters is still relatively rare. This article will introduce a research idea of ​​the performance test system of the central swivel joint, and give the reference of the design of the corresponding slewing mechanism and hydraulic system Program.
