    摘要: A relatively inexpensive and reliable latching mechanism for locking or otherwise securing a tailgate to the cargo area of a vehicle or trailer is provided comprised of a latch plate of unitary construction and a locking pin. The latch plate is further comprised of a mounting base having means for attachment to the vehicle or trailer sidewall and an offset projecting lug having a lanced tab for receiving the locking pin. In a preferred embodiment, the mounting base is attached to the vehicle side wall and the lanced tab projects through a complimentary closed slot in the tailgate and receives the locking pin thereby securing the tailgate between the offset, the projecting lug and the lanced tab. The offset projecting lug creates a space between the vehicle side wall and the projecting lug which traps a portion of the tailgate which forms the closed slot therebetween to add additional strength and stability to the attachment.

    摘要: A weight distributing hitch for towing a trailer includes a hitch bar, a ball mount head and spring bars for distributing the weight of the trailer relative to a towing vehicle. The spring bars include mounting trunnions and the ball mount head includes cooperating sockets for receiving those mounting trunnions. The spring bars are installed in the ball mount head by inserting a first end of the mounting trunnion in a first cooperating mounting socket, passing a second end of the mounting trunnion through a channel communicating with a second cooperating mounting socket and engaging the second end of the trunnion in the second cooperating mounting socket.

    摘要: A weight distributing hitch for towing a trailer behind a vehicle includes a hitch bar for mounting to the vehicle and a ball mount head for mounting on the hitch bar at a selected tilt angle. A pair of spring bars are mounted to the ball mount head. These spring bars distribute the weight of the trailer relative to the vehicle. Each spring bar is substantially L-shaped and includes a turned groove at a proximal end received in a cooperating aperture in the ball mount head. A retainer of spring steel engages in the grooves to hold the spring bars in position. The relative tilt angle of the ball mount head is adjusted by means of an eccentric angle adjusting element in the form of a washer. This washer is fixed to one of the ball mount head or hitch bar and includes a cam surface for engaging the other of the two elements.

    摘要: Right- and left-hand steering clutch and brake control valves each include a valve plunger, brake control spool and clutch control spool arranged in serial order in a valve bore with coil compression springs being interposed between the plunger and brake control spool, between the brake and clutch control spools and between the clutch control spool and an end of the bore. The reacting force on the control spools is a spring and constant hydraulic force while the applied force is by way of springs and hydraulic function pressure.
