[0002] At present, in the press-fitting process of urban rail transit vehicle brake accessory bushings, the assembly process is from putting on the parts to putting on the bushings and then to press-fitting. The whole process is performed by manually operating the hydraulic cylinder to press-fit a single bushing; the oil unloading pressure is reached by the cylinder to ensure the size of the cylinder's pressing force.
