    Abstract: This invention relates to a two-path hydromechanical transmission mounted on the caterpillar vehicle or the like and to a method of controlling the same, in which excellent operability and straight advancement performance can be obtained in a low speed zone and a high efficiency of power transmission is possible even in a high speed zone, using a small-capacity hydraulic pump and hydraulic motor. For attaining the above effects, the transmission is composed of: hydraulic pumps (2), (3) disposed independent from each other on the right and left sides and driven by an engine and hydraulic motors (4), (5) disposed in the same way as above; a power transmission path provided with reduction gear trains (100), (159) for transmitting output torque from the motors to the driving wheels and planetary reduction gear trains (200), (250); and another power transmission path provided with a reduction device (300) including bevel gears for dividing output torque from the engine rightward and leftward and with the abovesaid planetary reduction gear trains (200), (250) for transmitting output torque to the driving wheels on the right and left sides. This apparatus is separately controlled for running in the low and high speed zones.

    Abstract: A selectable flow divider drive system includes a hydraulic fluid reservoir and a plurality of drive motors in fluid communication with the hydraulic fluid reservoir. A hydraulic pump is connected between the hydraulic fluid reservoir and the plurality of drive motors and directs hydraulic fluid from the hydraulic fluid reservoir to the plurality of motors. The hydraulic pump is operable in a high flow condition and a low flow condition. A flow divider component is interposed between the hydraulic pump and the plurality of motors. The flow divider component selectively divides hydraulic fluid flow to each of the plurality of drive motors, where a flow divider of the flow divider component is sized for the low flow condition of the hydraulic pump. A bypass valve is disposed upstream of the flow divider that selectively bypasses the flow divider when the hydraulic pump is operated in the high flow condition.
