Abstract

An electromagnetic drive locking separated hydraulic centering cylinder mainly comprises a centering cylinder left cylinder block, a centering cylinder right cylinder block, a middle cylinder block, a piston rod, a piston, a left floating piston, a right floating piston, a left connecting flange, a right connecting flange, a self-hold electromagnet and a locking piston. The left end of the centering cylinder left cylinder block and the left connecting flange are connected into a whole through welding. The left end of the centering cylinder right cylinder block is connected with the left connecting flange into a while in a welded mode. The middle cylinder block is connected with the left connecting flange and the right connecting flange through bolts, so that the centering cylinder left cylinder block, the centering cylinder right cylinder block and the middle cylinder block are connected. The left floating piston and the right floating piston are located on the two sides of the piston correspondingly. An annular wedge-shaped groove is formed in the middle of the piston. A square hole is formed in the upper end of the middle cylinder block. An exhausting plug used for exhausting gas in the annular wedge-shaped groove is arranged in the lower portion of the middle cylinder block. The electromagnetic drive locking separated hydraulic centering cylinder is simple and compact in structure, small in size, low in weight, easy to machine and capable of achieving the energy saving purpose, and has important significance in improving the operating stability of an automobile.

Description

technical field [0001] The invention belongs to an auxiliary device in a rear wheel steering system in a multi-axle automobile, in particular to a hydraulic centering cylinder for electromagnetic driving and locking of the rear wheel steering in an automobile. Background technique [0002] In recent years, with the rapid development of logistics transportation and engineering construction, large and heavy-duty commercial vehicles such as civilian trucks, large logistics vehicles, and special vehicles have gradually become the first choice for road transportation due to their low transportation costs and high efficiency. This kind of heavy-duty vehicle has a large mass, a large moment of inertia, a high center of mass and a large wheelbase. The whole vehicle has more than three axles and has multiple non-steering axles. It is very urgent to have high mobility, quick response, and high passability. , the rear wheel steering technology came into being. The traditional mechanic...
