    摘要: An improved valve for use in a hydrostatic drive apparatus for a vehicle such as a zero turn vehicle. For each hydraulic drive system in the vehicle, a valve is located between the high and low pressure sides of the closed hydraulic circuit connecting the hydraulic pump and motor. The valve opens when the pressure rise rate in the high pressure side reaches a set level to minimize pressure spikes in the high pressure side and thus improve performance of the vehicle. A valve block may be used to mount the valve, and a second valve may also be included therein to connect the two pressure sides of the hydraulic circuit in a similar manner when the vehicle is operated in reverse.

    摘要: A mechanism for sensing the direction of a vehicle, or other application using a drive device such as a hydrostatic transmission. An actuation mechanism is mounted to a rotatable shaft or gear in the drive device and has an actuated position when the shaft or gear is rotating in a first direction and an unactuated position when the shaft or gear is rotating in the opposite direction.

    摘要: A dual pump apparatus for use on a vehicle or industrial application having a housing in which a pair of hydraulic pumps are mounted and driven by a prime mover. The prime mover is drivingly coupled to a main input shaft, which drives the hydraulic pumps. An auxiliary pump may be drivingly coupled to the main drive shaft and a power take off unit may also be connected thereto. The power take off unit may be driven by a power take off unit output drive shaft, on which a cooling fan may be attached.
