  • Patent number: 7454907
    Abstract: An axle driving apparatus including a hydrostatic transmission disposed in a housing, with at least one axle extending from a side of the housing and an input shaft extending into the housing to drive the hydrostatic transmission, an output shaft engaged to and driven by the hydrostatic transmission and having one end external to the housing, a brake mechanism engaged to the external end of the output shaft, a trunnion engaged to the hydrostatic transmission and having one end extending from the housing, and a bypass actuator engaged to the hydrostatic transmission and having one end extending from the housing, wherein each of the axle, output shaft, trunnion, and bypass actuator are oriented generally perpendicular to the input shaft, and each of the output shaft, trunnion and bypass actuator extend from the same side of the housing.

  • Patent number: 7430942
    Abstract: A hydrostatic transmission mountable to a vehicle frame. The hydrostatic transmission is adapted to removeably receive an axle shaft. The hydrostatic transmission is also adapted to be mounted to at least one of two opposed side members of the vehicle frame. The opposed side members have openings through which the axel shaft passes. The vehicle may be a snow thrower.

  • Patent number: 7278263
    Abstract: A charge pump design for a hydraulic drive apparatus such as a hydrostatic transmission, integrated hydrostatic transaxle or pump having a rotatable pump cylinder block mounted in a sump and connected to a hydraulic circuit by means of a center section or the like. A fluid gallery for charge fluid is in communication with the hydraulic circuit and the charge pump is mounted adjacent to and is driven by the pump cylinder block to provide hydraulic fluid from the sump to the fluid gallery. The charge pump can be of many different styles such as a gerotor, a centrifugal pump or a flexible impeller style.

  • Patent number: 6804958
    Abstract: A hydrostatic transmission may be placed in a free-wheeling state by rotating a bypass actuator that lifts the motor from a motor running surface whereby hydraulic fluid flows into a transmission cavity. A bypass arm connected to the bypass actuator and to a bypass rod may be used to engage and disengage the bypass actuator via operation of the rod. Further, a bypass latch may be used to lock the bypass arm in an engaged position whereby the bypass actuator is engaged and the transmission is disengaged. The bypass latch arm is preferably linked to the brake pedal whereby actuation of the brake pedal disengages the bypass actuator through operation of the latching arm. The system may be designed to provide dynamic braking through transmission resistivity prior to application of a brake force to the axles or wheels by unlatching the bypass arm prior to actuating the brake arm.

  • Patent number: 6397594
    Abstract: A hydrostatic transmission design incorporating a unique housing shape and configuration, including a vertical split of the two casing elements, which are shaped to conform to the internal components of the transmission. The center section of the transmission has a unique configuration including a trunnion mounted swash plate, means for mounting the center section to the transmission and a motor output shaft mounted below the pump running surface. The transmission also includes an expansion chamber, preferably secured externally to the sump, having a tube mounted therein to transfer hydraulic fluid between the chamber and the sump.
