TRANSMISSION FOR OIL PRESSURE OPERATION

摘要

PURPOSE: A transmission for oil pressure operation is provided to simplify structure and to reduce a cost by using a small motor of variable capacity. CONSTITUTION: A transmission for oil pressure operation comprises: a gears power transmission device (5) to connect a variable-capacity motor(3) with high speed - low torque and a variable-capacity motor(4) with low speed - high torque with a common output shaft(2); a clutch device(7) to detach and connect the variable-capacity motor with low speed - high torque with the output shaft; a control pump(10) to be operated by the variable-capacity motor with high speed - low torque and to generate detachable oil pressure of the clutch device; where the gears power transmission device comprises a first input shaft(6), a driven shaft, a second input shaft(9) and the output shaft.
