Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic retarders, and in particular relates to a stator impeller of a hydraulic retarder. Background Art

[0002] The hydraulic retarder is an auxiliary braking device for an automobile. The hydraulic retarder includes a heat exchanger, a rotor impeller, a stator impeller, a transmission shaft, a housing and a working chamber cover. The housing is provided with an oil storage chamber, and the working chamber cover is covered on the housing to form a working oil chamber. The rotor impeller and the stator impeller are both located in the working oil chamber and are arranged in opposition. The rotor impeller, the stator impeller and the working chamber cover are all sleeved on the transmission shaft. The rotor impeller rotates synchronously with the transmission shaft, and the transmission shaft rotates synchronously with the input shaft of the automobile gearbox. In this way, the vehicle can be decelerated by applying a damping force to the rotor impeller.

[0003] When installing the existing stator impeller, the stator impeller is installed on the rotor of the hydraulic retarder by means of multiple bolts with the cooperation of external tools. However, due to the excessive number of bolts, the staff is required to turn each bolt in turn, which is extremely time-consuming. Secondly, the bolts are prone to thread slippage during long-term use, which makes it extremely difficult to remove the stator impeller later, and is not convenient for subsequent replacement and maintenance of the impeller. Therefore, we provide a stator impeller for a hydraulic retarder. Utility Model Content
