Abstract
The invention discloses a double-cylinder hydraulic jack for vehicles. The double-cylinder hydraulic jack is characterized in that when a right hydraulic stressing rod (4) and a left hydraulic stressing rod (26) move upwards, a right hydraulic cylinder check valve (10) and a left hydraulic cylinder check valve (20) are opened, a left cylinder piston (21) and a right cylinder piston (9) move upwards, jacking cylinder check valves (14 and 15) are closed and hydraulic oil in a bottom oil cylinder enters a left hydraulic cylinder and a right hydraulic cylinder; when the right hydraulic stressing rod (4) and the left hydraulic stressing rod (26) move downwards, the right hydraulic cylinder check valve (10) and the left hydraulic cylinder check valve (20) are closed, the left cylinder piston (21) and the right cylinder piston (9) move downwards, the jacking cylinder check valves (14 and 15) are opened, the hydraulic oil in the two hydraulic cylinders enters a jacking cylinder through the jacking cylinder check valves (14 and 15), and therefore a jacking piston in a main cylinder body moves upwards, and the jacking effect is realized. The double-cylinder hydraulic jack for the vehicles is of a symmetric structure, and if one of the left hydraulic cylinder and the right hydraulic cylinder is broken down, the other one can work normally.
Description
Technical field:
