Traction distributing apparatus for motor vehicle

摘要

A traction distributing apparatus for a motor vehicle includes a housing, a propeller shaft arranged on the input side of the housing and driven by an engine, and a differential gear mechanism arranged on the output side of the housing for distributing torque from the propeller shaft to axles. A reversible hydraulic motor is arranged on the output side of the housing to provide relative torque between the axles by pressure oil supplied and discharged from the outside. The hydraulic motor comprises a motor casing rotatably arranged on the output side of the housing and a cylinder block rotatably arranged inside the motor casing for rotating relative thereto by means of pressure oil. The motor casing serves as part of one of the axles.
