[0003] The oil storage cavity of the hydraulic retarder is connected with an exhaust channel, and the exhaust channel is connected to the external atmosphere for discharging the compressed air in the oil storage cavity when the hydraulic retarder is not working. However, in the prior art When the compressed air in the hydraulic retarder is discharged through the exhaust channel, the compressed air often contains a certain amount of oil, and the oil contained in the discharged compressed air will pollute the surrounding environment

The invention discloses an oil-gas separation device of a hydrodynamic retarder. When the hydrodynamic retarder exhausts compressed air, the compressed air enters an oil-gas separation part through an intake port of a bottom cover, and then flows out from the oil-gas separation part; when the compressed air flows out from the oil-gas separation part, the compressed air passes through a non-woven fabric layer, a glass fiber layer and a non-woven fabric layer in sequence; after the compressed air flows out from the oil-gas separation part, the compressed air spirally flows upwards along the inner wall of a cylindrical cover shell, and then is exhausted into external atmosphere through exhaust holes in the cylindrical cover shell; and when the compressed air spirally flows upwards along the inner wall of the cylindrical cover shell, oil remained in the compressed air can be absorbed on the inner wall of the cylindrical cover shell. The oil-gas separation device of the hydrodynamic retarder can separate the oil in the exhausted compressed air to reduce the oil content of the exhausted compressed air.
Description
technical field [0001] The invention relates to an oil-gas separation device for a 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 is working, 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. At the same time, the oil moves along the direction of the rotor blades and flings to...
