Abstract

The invention provides a rear wheel steering hydraulic cylinder of an automobile. The hydraulic cylinder comprises a cylinder body I and a cylinder body II which are coaxially arranged, wherein an end cover I, and end cover II and a middle end cover are radially arranged at two ends of the cylinder body I and the cylinder body II as well as between the cylinder body I and the cylinder body II respectively; a piston rod penetrating through the end cover I, the middle end cover and the end cover II is arranged at axes of the cylinder body I and the cylinder body II. The hydraulic cylinder is characterized in that a piston is radially arranged on the piston rod between the end cover I and the middle end cover; bosses I are radially arranged on the piston rod between the middle end cover and the end cover II at intervals, an axially floating piston I is arranged on the piston rod between the bosses I and the middle end cover, and an axially floating piston II is arranged on the piston rod between the bosses I and the end cover II. Compared with the prior art, the rear wheel steering hydraulic cylinder of the automobile is simple in structure, safe and reliable and integrates steering, centering and locking functions.

Description

technical field [0001] The invention relates to a steering hydraulic cylinder, in particular to an automobile rear wheel steering hydraulic cylinder integrating the functions of steering, centering and locking. Background technique [0002] With the development of heavy-duty vehicles and military vehicles, the vehicle load is getting larger and larger, the number of axles is increasing, and the length of the vehicle body is also lengthening. Correspondingly, problems such as severe tire wear, large turning radius, and poor handling stability have become increasingly prominent, and the inventor has found through long-term research that rear wheel steering is an effective way to solve these problems. [0003] The electronically controlled hydraulic rear wheel steering is only advantageous for medium-sized or heavy vehicles with a tonnage of more than 5 tons; for cars, the electronically controlled electric type is the best, in which the electronic control unit controls the flo...
