The invention discloses a novel piston body assembly of a cylinder-pump integrated hydraulic turnover electric pump, and belongs to the field of automobile accessories. The novel piston body assemblyof the cylinder-pump integrated hydraulic turnover electric pump comprises a headstock, a fixed shaft seat is fixedly welded at the lower end of one side of the headstock, a rotating shaft is slidablysleeved in the fixed shaft seat, a fixed ring is fixedly welded at the outer end of one side of the rotating shaft, a pin body is inserted in one end of the rotating shaft in a fastened mode, and a piston rod is fixedly welded to one end of the pin body. According to the novel piston body assembly of the cylinder-pump integrated hydraulic turnover electric pump, a threaded sleeve is rotated anticlockwise to be separated from the rotating shaft, and the piston rod is convenient to detach for inspection, maintenance and replacement. Due to the design of the pin body, the connecting strength ofthe piston rod and the rotating shaft can be enhanced, and stress bending force borne by the connecting position of the piston rod and the rotating shaft is reduced. A nut is rotated anticlockwise todrive a rubber gasket and a threaded rod to move out, a filter screen can be conveniently detached upwards for cleaning and flushing, and hydraulic oil in an oil groove can be prevented from overflowing outwards through the design of the rubber gasket.
Description
technical field [0001] The invention relates to the field of auto parts, and more specifically relates to a novel piston body assembly of a cylinder-pump integrated hydraulic reversing electric pump. Background technique [0002] The competition in the truck industry is becoming more and more fierce, and auto parts are constantly being updated. Higher quality, safer and more comfortable products are constantly being introduced. The cab, the main component of the truck, is no exception. In order to facilitate the inspection and maintenance of the engine , Maintenance, the cab is required to be turned forward, and the turning of the heavy-duty vehicle cab is mainly achieved by using the hydraulic turning mechanism to overcome the gravity moment of the cab. [0003] The new piston body assembly of the existing cylinder pump integrated hydraulic flip electric pump, the connection between the oil cylinder and the car head is more complicated, and maintenance personnel need to spe...
