Stator pump stopping wheel used for parallel hydrodynamic retarder

The invention relates to the field of machinery design and discloses a stator pump stopping wheel used for a parallel hydrodynamic retarder. The stator pump stopping wheel used for the parallel hydrodynamic retarder comprises a pump stopping wheel body, a traction groove, pump blades and connecting discs. By means of the optimal design of the structure, the quantity of oil inlet square holes in the pump blades can be reduced, the areas of the oil inlet square holes can be increased, the smoothness of the oil inlet square holes can be improved and the deformation quantity of the oil inlet square holes can be reduced, so that the oil inlet quantity of the retarder can be met and the torque of the retarder can be increased, and furthermore the speed reducing capacity of a car can be improved and the using effect of an oil-gas-combined hydrodynamic speed reducer can be improved; a plurality of sealing grooves are added in the inner wall of a round through hole which is formed in the reasonably-designed stator pum
