High-efficient braking hydraulic retarber

The utility model discloses a high-efficient braking hydraulic retarber, including casing, driving wheel, fixed wheel, heat exchanger and oil tank, driving wheel and fixed wheel are installed in inside and the two coaxial phase of casing to setting up, all be equipped with the blade on the opposite face of said driving wheel and fixed wheel, the blade is put for back loading type to one side to the blade on the driving wheel, the driving wheel passes through the shaft rotation and connects in the casing, it establishes ties to separate and is connected to carry out synchronization through separation connecting device between shaft and the power shaft, the utility model discloses a high-efficient braking hydraulic retarber adopts back loading type to put the blade to one side, can weaken or eliminate backward flow, secondary flow influence in the flow field, improves braking effect, and the synchronous separation of establishing ties is connected between driving wheel and the power shaft, need not with the discharge of the fluid in the casing simplification oil circuit structure, reduction manufacturing and use cost during the non-braking of vehicle.
