    摘要: An HST propel system includes first and second pumps having displacements variable in response to movement of first (31) and second (33) control shafts, respectively; and a linkage arrangement for moving the control shafts in unison in response to movement of an operator input (37). The linkage arrangement comprises a crank arm (35) rotatable about its axis in response to movement of the input device, first (41) and second (51) input arms fixed relative to the crank arm, and first (45) and second (55) elongated control rods pivotally connected to the input arms. The system includes a swivel connector (43) cooperating with its input arm to define a swivel axis (S.A.1), fixed relative to the axis of the crank arm, and a swivel connector (53) cooperating with its input arm to define a swivel axis (S.A.2), moveable relative to the axis of the crank arm for straight tracking adjustment.

    摘要: Apparatus are provided which utilize the tailgate of a vehicle, such as a pick-up truck, to create an aerodynamic windspoiler for the vehicle. In one form, the apparatus includes a housing is pivotally attached to the vehicle, and a rod having a first end supported within the housing and a second end attached to the tailgate, wherein the rod is capable of being slidably extended and retracted from the housing. Ideally, the positioning of the rod relative to the housing is controlled relative to the speed of the vehicle to adjust the inclination of the tailgate. This may be accomplished utilizing either an electrically driven motor or an hydraulic cylinder. In another form, the apparatus includes a rotatable shaft attached to a sheet of stretch resistant material. Upon extending and attaching the sheet of material to the tailgate, a windspoil is created.
