    摘要: A hydrostatic pump unit is located within a housing which serves also as a hydraulic fluid sump. A displacement control valve for controlling actuators for adjusting the angular position of a swashplate of the pump unit is mounted on the exterior of the housing. Disposed along the axis about which the swashplate is adjustable and joining the swashplate to a shiftable sleeve of the control valve is a feedback shaft which acts to return the valve to a null condition when the swashplate arrives at a commanded new displacement effecting position. The feedback shaft has a passage extending therethrough which acts as a drain connection between the valve and the sump defined by the housing. A check valve is located in the passage for preventing fluid from draining from the housing when the valve is disconnected from the feedback shaft for service.

    摘要: A trailer (10) is provided having a framework (12) carrying ground engaging wheels (14), a body (16) having a corrugated bottom wall and defining a storage compartment and a tiedown fastener for securing the body to the framework through the corrugated bottom wall. The trailer includes an interchangeable top (18) and tailgate. The trailer also includes a novel spring assembly. The spring assembly includes a leaf spring with an anchoring aperture at one end and a mounting tongue at the other. The mounting tongue is captured between the framework and a fastener and provides relative sliding movement. Additionnally, the sidewalls of the trailer include aligned slots (70) that receive a strut which supports an optional shelf.

    摘要: A weight distributing and sway controlling hitch assembly for towing a trailer behind a vehicle includes a hitch bar for mounting to a vehicle. The hitch assembly also includes a ball mount head carried on the hitch bar and a hitch connector carried on the ball mount head. A pair of friction pads are also provided for mounting on the trailer. Additionally, the hitch assembly includes a pair of shoes, each of the shoes being received on one of the pair of friction pads while allowing relative sliding movement thereto. Still further, the hitch assembly includes a pair of spring bars for distributing trailer weight relative to the vehicle. Each of the spring bars includes a proximal end mounted to the ball mount head and a distal end for engaging one of the shoes.

    摘要: An external band brake control linkage includes a pair of anchor pins which are respectively connected to the opposite ends of a brake band. The linkage being operable between a normal released condition holding the anchor pins spaced apart so as to maintain the band disengaged from the brake drum and an operative condition wherein the anchor pins are moved together from the position they occupy when the linkage is in its released condition wherein the brake band is engaged with the brake drum. For the purpose of compensating brake band wear, the control linkage includes a link having a ratchet wheel-type adjusting nut threaded on a rod-like link thereof, the adjusting nut being advanced so as to change the spacing between the anchor pins. A paw or an adjusting nut operating lever is carried by a link of the control linkage and is operative in response to the link undergoing a predetermined movement, corresponding to brake band wear, to index the adjusting nut so as to compensate for wear.
