PURPOSE: A hydraulic motor of a rotating pump type is provided to remove the need for a sprocket and a chain since a first motor rotates by the hydraulic pressure due to the pedaling of a bicycle and a second motor, to which a rear wheel is coupled, rotates. CONSTITUTION: A hydraulic motor of a rotating pump type comprises a motor(m1), a tubular pipe(t2), a valve(v1), a hydraulic unit(p1), transmission(c1) and a speed control unit(c9). The motor is driven in pair. The tubular pipe is coupled to the motor and serves as a frame and a communicating pipe. The valve is installed on and under the motor to control the flow of hydraulic pressure. The hydraulic unit maintains the hydraulic pressure. The transmission controls speed. The speed control unit is connected to a cable and operates. |
