  • Patent number: 4988120
    Abstract: System for connecting an axle bracket of a race vehicle to the chassis of the vehicle. A first connecting member is connected to the axle bracket below the axle and extends forward to the chassis, and a second connecting member is connected to the axle bracket above the axle, and extends rearward to the chassis. This causes both connecting members to be in compression when the front end of the vehicle lifts upon rapid acceleration, and reduces chassis flex and improves the structural integrity of the chassis. The system may also include a wheelie bar connected by a third connecting member at an intermediate point of its length to the rear portion of the chassis. This improves traction of the rear wheels by reducing the load borne by the wheelie wheels when the contact the pavement.

    Abstract: Heavy load-carrying vehicles such as concrete trucks occasionally require the temporary addition of extra load-carrying wheels in order to reduce load concentrations transmitted to highways to within allowable limits as set by statute and/or regulatory agencies in various states. This invention is directed to a load-carrying unit adapted for attachment to the frame of a heavy load-carrying vehicle such as a concrete truck or the like for mounting outside of both sides of the frame thereof for movement between retracted and load-sharing positions. The load-carrying unit includes first and second wheel assemblies which are movable between the retracted and load-sharing positions independently of each other, each wheel assembly including wheels mounted for rolling engagement with the highway and for rotation about an approximately vertical axis located forwardly of the wheels.

  • Patent number: 4053072
    Abstract: A container transport system in which a trailer has primary rear load carrying wheels which can be elevated to transfer ground contact to caster wheels and lower the trailer bed, and in which a leg-mounted pallet frame has a center guide slot into which a central guide post at the rear of the trailer is maneuvered while the trailer is backed on the caster wheels to assist in properly aligning the trailer beneath the pallet frame, whereupon the primary wheels are lowered to lift the pallet frame free of the ground for transport on the trailer.

  • Patent number: 4007949
    Abstract: A loading bar is mounted on a leaf spring of a racing vehicle rear axle suspension system to increase traction on the vehicle tires during acceleration. Strut tube and strap members are mounted in a spaced relationship on the vehicle leaf spring rearwardly and adjacent to the vehicle axle by a pair of U-bolts and reinforcing plates. The tube and strap members extend rearwardly from the axle and are joined at their extended ends by a wheel bracket and a strut tube adjusting channel. The strut tube extends in an upwardly angled direction between the adjusting channel and axle, with the strap member being generally parallel with respect to the ground or racetrack. A wheel or roller is mounted on the wheel bracket and is spaced above the ground when in static condition. The loading bar is readily adjustable on the leaf spring to change the traction aiding effect thereof.

  • Patent number: 3997191
    Abstract: A castor wheel, preferably of the swivel type is mounted at the distal end of a leg support which is in turn connected to pivot on an axle transverse and beneath the tongue of a trailer. Means are provided to connect a winch associated with the trailer tongue to the leg support opposite the castor. The application of force through the winch pulls the castor wheel downward beneath the trailer tongue, thereby adjusting the elevation of a hitch mechanism carried by the trailer tongue.

  • Patent number: RE30581
    Abstract: A removable frame for reduction of axle loads for heavy vehicles is disclosed herein. The frame includes a pair of lever arms pivoted to each other at one end with adjustable biasing means between the free ends of the lever arms. One of the lever arms has at least one wheel supported thereon while the other arm is rotatably connected to a support member adapted to be attached to a vehicle frame. A centering mechanism normally maintains the lever arm in a predetermined position on the support member and accommodates rotation with respect to each other.
