摘要:
A method and apparatus for long vehicles to make sharp turns on city streets without running up on the curb. The back wheels of the vehicle are steered with the aid of a guide control wheel so that when the semi or truck is making a sharp turn, the rear wheels continue straight down the street to the intersection and then turn, even though the semi and the front of the trailer have already turned in a normal manner.

A fifth wheel for coupling a tractor to a trailer carrying a kingpin. The fifth wheel comprises a mounting structure adapted to be mounted to the tractor and a fifth wheel plate mounted to the mounting structure and a top bearing surface rotateable relative to the mounting structure about an axis normal to the top bearing surface in order to minimize the friction between the top bearing surface of the fifth wheel plate and the trailer.

The invention is an attachment for a fifth wheel trailer hitch generally mounted within the bed of a vehicle to prevent damage to the vehicle in the event that the fifth wheel hitch fails due to faulty hook-up, the invention including a horizontal cross bar, two perpendicularly attached side bars with paired sets of bolt holes for mounting to the fifth wheel trailer hitch, a slide channel attached to the horizontal cross bar having an upper catch plate secured to the slide channel, and at least four bolts with lock nuts.
摘要:
An adapter for attaching a gooseneck or fifth wheel trailer hitch to a standard, V-shaped, trailer hitch. The hitch converting device contains a fifth wheel frame that attaches about the standard hitch and ball of a trailer device. The adapter provides a simple mechanism, whereby two different styles of hitches can be alternately operated by the same vehicle, with minimum securement.
摘要:
A method of converting a refuse collection body into a semi-trailer. A refuse collection body having a front end and a rear end, and a frame extending along a bottom of the body from adjacent the front end to adjacent the rear end is provided. A king pin is mounted to the frame proximate the front end for attachment to a fifth wheel of a tractor and an axle assembly is mounted to the frame proximate the rear end.

A glider fifth wheel automatic adjustment assembly includes a support frame including a pair of spaced guide rails and a pair of upright assemblies attached to the guide rails. Each upright assembly includes a lower sleeve portion for receiving a respective guide rail, an intermediate housing portion vertically above the sleeve portion, and an upper mounting portion vertically above the housing portion. A head assembly may be adjustably mounted between respective housing portions of the upright assemblies. At least one roller is positioned within each housing portion of the upright assemblies such that the at least one roller contacts an upper surface of an upper guide rail. In addition, the glider fifth wheel attachment assembly includes a latching assembly for releasably locking the glider fifth wheel attachment assembly between a first and a second position.
摘要:
An assembly for coupling a truck tractor to a semi-trailer. The assembly comprises an upper coupling plate, an intermediate plate, and a back plate. The upper coupling plate has an opening for receiving the kingpin. The intermediate plate is positioned on an upper surface of the upper coupling plate and has a portal for receiving a portion of the kingpin. The back plate is positioned adjacent the intermediate plate. A double shear attachment means joins the upper coupling plate, the intermediate plate, and the back plate are along a first shear plane and a second shear plane.

A gooseneck trailer coupler is disclosed which secures a first structure such as a towing vehicle to a second structure such as a trailer. The coupler is provided with a mounting element extending from the first structure, a chuck having a top end and a base at a bottom end opposite the top end, with the chuck attached to the mounting element at the top end and adapted to receive a ball mounted to the second structure. A locking assembly is adapted to releasably secure the ball and the chuck, and comprises a ring gear mounted around the chuck and movable from a locking position where the chuck is secured with the ball and an unlocking position where the chuck is unlocked from the ball, wherein the ring gear translates from the base toward the top end of the chuck as the ring gear moves from the locking position to the unlocking position. The locking assembly can also comprise at least one jaw mounted in the chuck for engaging the ball when the ring gear is in the locked position. A novel release lever assembly is also disclosed which moves the ring gear.
摘要:
A fifth wheel is described with a coupling plate having elements for fastening to the vehicle frame. It is supposed to facilitate the mounting on the vehicle frame, while it should be possible to equalize manufacturing tolerances of the frame in simple fashion. The fastening elements attach to pivot pins, which are detachably arranged on the fifth wheel and project outward to the side beyond the coupling plate.
摘要:
An articulated air suspended hydraulic-dampened fifth wheel hitch coupling device for isolating the front of a fifth wheel or goose neck trailer hitch from the shock of bumps in the road and the inertia of movement of the trailer. Two inflatable air springs operatively connected to the pressurized air system of the tow vehicle eliminates vertical fifth wheel load from being transferred from the trailer to the tow vehicle. Additionally, an oscillating rocker connected transversely to the direction of travel of the vehicle allows the fifth wheel hitch to pivot in a transverse motion to eliminate load from being transferred from the trailer to the tow vehicle.
