Synchronization device of the jacks and hydraulic jack which relates to a synchronization device

摘要

The mechanism for synchronising several hydraulic actuators activated simultaneously by a single control signal comprises a threaded shaft (12,22,32) for converting translational movement into rotational movement integrated in each actuator (10,20,30). The shafts are coupled to the piston (11,21,31) of the corresponding actuator. Each actuator has a pinion (13,23,33), connected to the converter, which mesh with an open toothed ring (40). The movement conversion comprises and assembly of nuts and bolts integrated in each actuator piston, the nut being fixed to the piston. The bolt is constituted by the threaded region of the shaft which rotates in the actuator in bearings.
