Abstract

The invention discloses an oil and air separation structure for a hydraulic retarder. The oil and air separation structure comprises an exhaust passage and an oil return passage, wherein one end of the exhaust passage is communicated with an oil storage cavity, the other end of the exhaust passage is communicated with the external atmosphere, one end of the oil return passage is provided with an oil collecting hole used for collecting oil leaked from a work cavity, the other end of the oil return passage is communicated with the oil storage cavity, and an oil and air separation device used for carrying out oil and air separation on exhausted compressed air for returning the separated oil to the oil storage cavity through the oil return passage is connected in series on the exhaust passage. The oil and air separation structure has the advantages that oil in the exhausted compressed air can be separated and recovered, and the oil content of the exhausted compressed air can be reduced.

Description

technical field [0001] The invention relates to a hydraulic retarder, in particular to an oil-gas separation structure of the hydraulic retarder. Background technique [0002] The hydraulic retarder is an auxiliary braking device for automobiles, mainly used in large passenger cars, urban public transport vehicles, heavy trucks and military vehicles. The hydraulic retarder includes a heat exchanger, a rotor, a stator and a shell. The shell has The oil storage chamber and the working chamber, the rotor and the transmission system of the car are fixed together, and the rotor will also rotate when the car is running. When the hydraulic retarder works, the compressed air enters the oil storage chamber, and the oil in the oil storage chamber is pressed into the working chamber between the stator and the rotor of the hydraulic retarder. When the hydraulic retarder starts to work, the rotor drives the oil. The oil rotates around the axis, and at the same time, the oil moves in the...
