Gas-liquid combination novel driving cylinder

Abstract

The invention discloses a gas-liquid combination novel driving cylinder. The gas-liquid combination novel driving cylinder is characterized by comprising a gas cylinder back end cover, a gas cylinder piston, a gas cylinder barrel, a gas cylinder front end cover, a connecting flange, an oil cylinder back end cover, an oil cylinder piston, an oil cylinder barrel, a common piston rod, and an oil cylinder front end cover, wherein a gas-liquid combination cylinder is formed by connecting and combining a cylinder with an oil cylinder through the connecting flange; the gas cylinder back end cover and the gas cylinder front end cover are respectively mounted at two ends of the gas cylinder barrel; the gas cylinder piston is arranged near the gas cylinder back end cover; the common piston rod is arranged in the center position of the gas cylinder piston; the gas cylinder barrel is connected with the oil cylinder barrel through the connecting flange, and the oil cylinder back end cover is arranged in the connecting place; the oil cylinder piston is arranged; the front end of the oil cylinder barrel is the oil cylinder front end cover; and the common piston rod penetrates through the gas cylinder front end cover, the connecting flange, the oil cylinder back end cover, the oil cylinder piston and the oil cylinder front end cover in sequence. The gas-liquid combination novel driving cylinder has the following beneficial effects: the gas-liquid combination novel driving cylinder is efficient and energy-saved; the whole system design fully uses respective advantages of pneumatic transmission and hydraulic transmission; the pneumatic action is fast, and the response is fast, so that the idle stroke time is short, and the efficiency is high; and the hydraulic transmission is stable, the working travel is low in speed and controllable, and hydraulic oil cannot be compressed to keep the pressure, so that the demands on power control in the equipment technological process are totally satisfied.

Description

technical field [0001] The invention relates to a power device for an automatic wheel inflator of a car, and in particular provides a new type of gas-liquid combined driving cylinder. Background technique [0002] At present, the power control part of most domestic car wheel inflation equipment adopts hydraulic transmission control system. In order to improve production efficiency and realize high pressure and fast work, the power of the oil pump motor must be increased. In this way, the energy consumption is relatively prominent, and there are also problems Many problems, such as oil heating, leakage pollution, increased failure rate of hydraulic valves, large floor space, etc. Contents of the invention [0003] The purpose of the present invention is to solve the many technical problems mentioned above, and especially provides a new type of driving cylinder with gas-liquid combination. [0004] The invention provides a new gas-liquid combination drive cylinder, which is...
