Abstract:
A storage arrangement for lines from a tractor truck includes a housing member secured external to a cab of the truck, a receiver connected to the housing and configured to couple to a select one of an electrical line and first and second pneumatic lines, and a control arrangement coupled to the receiver such that upon coupling of one of the lines with the first receiver the control arrangement allows an operator to at least one of release brakes of the truck, release brakes of a trailer, and unlock a kingpin from a fifth wheel hitch plate assembly, wherein the control arrangement prevents the operator from the at least one releasing the brakes of the truck, releasing the brakes of the trailer, and unlocking the kingpin from the fifth wheel hitch plate assembly prior to one of the lines being coupled with the receiver.
Abstract:
A vehicle suspension assembly includes providing an axle assembly having a first end including a first mounting structure and a second end, providing a first bearing block and a second bearing block, forming a first aperture in the first bearing block and a second aperture in the second bearing block, attaching the first and second bearing blocks to the first mounting structure subsequent to forming the first and second apertures; and providing a first spindle assembly coupled to the first mounting structure by a first spherical bearing located within the first aperture and a second spherical bearing located within the second aperture, wherein a first kingpin assembly extends through the first and second spherical bearings, thereby coupling the first spindle with the first mounting structure.
Abstract:
A trailer hitch arrangement control system including a trailer sensor for sensing the position of a trailer relative to a trailer hitch assembly, a lock sensor for sensing the position of a locking mechanism, a control valve in fluid communication with a brake assembly of a trailer and operable between closed and open positions, wherein the brake assembly is engaged and disengaged, respectively, and wherein the brake assembly is positively biased toward the engaged position, and a controller coupled to the trailer sensor, the lock sensor and the control valve for determining whether the trailer hitch assembly is properly coupled to the hitch and generating a control signal to the control valve to actuate the control valve from the open position to the closed position when the trailer hitch assembly is improperly coupled to the hitch, such that the brake assembly remains in the engaged position.
Abstract:
A vehicle suspension assembly includes a vehicle frame rail, a slide rail extending longitudinally along the vehicle frame rail and slidably adjustable thereto, a support bracket extending downwardly from the slide rail, a trailing arm pivotably coupled to the support bracket, a spring member positioned between the trailing arm and the slide rail, and an elastically resilient coupling arrangement coupling the slide rail to the vehicle frame rail, wherein the coupling member is configured to elastically deform during vertical displacement of the vehicle frame rail with respect to the slide rail.
Abstract:
A vehicle impact energy absorption arrangement includes a vehicle frame, a slider suspension arrangement coupled to the vehicle frame and including an axle member, and a spring member biasing the axle member, and an impact force absorbing arrangement that includes a mounting member coupled to the vehicle frame, first and second pivot members each pivotably coupled to the mounting member, and an elastically deformable biasing member positioned between each of the pivot members and the mounting member, wherein each of the pivot members is configured to pivot and elastically deform the at least one biasing member when impacted.
Abstract:
A fifth wheel mounting assembly comprises first and second support members adapted to couple to frame members and support assembly that comprises first and second portions slidably engaging the first and second support members and adjustable along a length thereof, the first and second portions including an upwardly-opening recess, first and second mounting members coupled to the first and second portions and configured to pivotably support the fifth wheel hitch plate, and a center portion having a first and second end received within the recesses of the first and second portions, wherein the recesses of the first and second portions are configured to receive the ends of the center portion subsequent to the first mounting member being coupled to the first mounting portion and the second mounting member being coupled to the second mounting portion.
Abstract:
According to the present invention, a fifth wheel hitch assembly includes a support bracket adapted to operably couple with a vehicle frame. The hitch assembly also has a hitch plate that includes a throat adapted to receive a kingpin of a trailer and a rear portion. The hitch plate is pivotably coupled with the support bracket and is pivotable between a first position and a second position. Further, the hitch assembly has a limiter linkage that includes a first end pivotably coupled with the rear portion. A second end of the limiter linkage is movable between a stowed and a deployed position. In the stowed position the second end is spaced from the vehicle frame. In the deployed position the second end of the limiter linkage is detachably coupled with the vehicle frame, thereby limiting movement of the hitch plate between the first and second positions.
