The invention discloses a hydraulic oil circulating system for a hydrodynamic retarder. The system comprises a housing and a heat exchanger; a working oil cavity and a mounting groove for mounting a bearing are arranged in the housing; a first oil outlet hole is arranged in the circumferential wall of the working oil cavity; an oil inlet hole is arranged in the circumferential wall of the mounting groove; a first oil inlet hole, a first oil outlet hole, a second oil inlet hole and a second oil outlet hole are arranged in the heat exchanger; the first oil outlet hole is communicated with the first oil inlet hole of the heat exchanger through a first channel; the first oil outlet hole of the heat exchanger is communicated with the oil inlet through a second channel; an one-way valve is arranged on the first channel; a second oil outlet hole is arranged in the circumferential wall of the working oil cavity and is communicated with the second oil inlet hole of the heat exchanger through a third channel; the second oil outlet hole of the heat exchanger is communicated with the oil inlet hole through a fourth channel. With the adoption of the system, the hydraulic oil can be cooled; in addition, the bearing can be continuously lubricated with the hydraulic oil.
Description
technical field [0001] The invention relates to a hydraulic oil circulation system on 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 shell and a heat exchanger. The shell has an oil storage chamber and a The working oil chamber is provided with a rotor impeller and a stator impeller. The rotor impeller and the output shaft of the automobile transmission case rotate synchronously. When the automobile is running, the rotor impeller also rotates. When the hydraulic retarder is working, compressed air enters the oil storage chamber, and the hydraulic oil in the oil storage chamber is pressed into the cavity between the stator impeller and the rotor impeller. When the hydraulic retarder starts to work, the rotor impeller drives the hydraulic oil Rotating around the a...
