し、スプロケツト又はタイヤに連結されている。 Hydraulic transmissions that connect the pump and motor in a closed circuit are installed independently on the left and right, and the output side of the prime mover is independently connected to the left and right pumps.
In hydraulically driven vehicles in which the output sides of the left and right motors are connected to sprockets or tires, the prime mover is usually installed so that its output shafts are aligned in the longitudinal direction of the vehicle body, and the pump input shaft is oriented in the same direction as the prime mover output shaft. The motor output shaft is installed in a direction perpendicular to the longitudinal direction of the vehicle body (the motor output shaft), and is connected to a sprocket or a tire.
