Abstract:
Provided is a rear guard structure system including: a chassis frame attached to the bottom of a vehicle; a plurality of guard stays having one ends hinge-coupled to chassis-frame hinges at both sides of the chassis frame through first hinges; and a rear guard attached to the other ends of the guard stays. A first stopper is mounted around the first hinge so as to restrict rotation of the guard stay, and includes a first buffer member to reduce shock or vibration when the rear guard is vertically vibrated.
Abstract:
A structure of an underrun protection bound to a plurality of brackets disposed at the front or rear portion of a frame of a vehicle is disclosed. A distal panel being disposed on a distal side of a longitudinal direction of the vehicle is bound to a proximal panel being disposed on a proximal side of the longitudinal direction at engaged overlapping parts each at which an edge of a flange of the distal panel is in contact with an edge of a flange of the proximal panel. A reinforcing panel is disposed at a binder part in a hollow, the underrun protection bound to the plurality of brackets at a plurality of the binder parts such that the reinforcing panel is in contact with the inner face of one of the proximal panel and the distal panel and is in contact with the engaged overlapping part.
Abstract:
Devices, methods, and systems for a leveling/spreading attachment are described herein. One system includes a body attachable to a push block portion of a trailer and a leveling blade coupled to the body. In some examples, a leveling blade trailer attachment system includes an adapter plate to replace a push block of a trailer, a body coupled to the adapter plate comprising a number of cylinders connected to an air supply of the trailer, and a leveling blade coupled to the body and the number of cylinders.
Abstract:
A rear impact guard includes a bumper support member configured to be coupled to a rear end of a vehicle and a horizontal bumper mounted at a lower end of the bumper support member. The bumper support member includes a generally triangular prism member having a generally triangular-shaped face, a vertical member, a horizontal member, and an angled member, and wherein the vertical, horizontal, and angled members are coupled to outer edges of the triangular-shaped face.
Abstract:
A frontal structure for a motor vehicle includes a deployable air dam movable from a stowed position to one or more deployed positions., wherein the. The frontal structure is configured such that when a collision event is detected, predicted or anticipated, the deployable air dam is deployed into a first deployed position in which an edge of the deployable air dam forms the lowest point of the frontal structure and the edge also extends to a point of the frontal structure that is at least as far forward as any other part of the frontal structure of the vehicle in the same vertical plane.
Abstract:
A trailer includes front and rear ends and a cargo area. A rear bolster extends transversely to a longitudinal direction at a bottom rear edge of the cargo area. A rear impact guard includes a bumper having opposing distal ends spaced laterally across the trailer. A pair of distal end supports connect to the distal ends of the bumper, each including a diagonal truss member and a vertical stabilizer. The diagonal truss extends along an axis in a forward, inward and upward direction from the bumper. The vertical stabilizer members are separate from the diagonal truss members and extend upwardly from the bumper to the rear bolster. The vertical stabilizer reduces an offset component of buckling load on the diagonal truss member upon rear impact. At least one inboard post extends between the bumper and the rear bolster at a location between the pair of distal end supports.
Abstract:
An underrun protection device for a vehicle comprises a hybrid beam formed of a preform member and a thermoplastic formed onto the preform member, and configured to attach to a vehicle attachment element, the hybrid beam comprises the preform member defines a channel and is configured to couple with the vehicle and extend along a side of the vehicle parallel with a centerline of the vehicle, with an opening of the channel oriented away from the centerline, wherein the channel is defined by an inside surface at least partially facing away from the centerline, and an outside surface at least partially facing the centerline; and a thermoplastic beam formed of the thermoplastic and shaped to conform to the channel of the preform member, the thermoplastic beam at least partially abutting the inside surface of the channel.
Abstract:
A roll off trailer is provided with a bumper assembly which may move between a deployed position and a collapsed position. The roll off trailer may include a trailer frame with a table top pivotally connected to the trailer such that the deployed position may be associated with a home position of the table top and the collapsed position may be associated with a tilted roll off position of the table top.
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 side under-ride collision guard is described that is configured to be mounted on a large trailer that has been equipped with a sliding rear axle, consisting of one or more energy absorbing beam structures axially adjustable for position attached to a multiplicity of parallel rails to diminish the impact hazard to other roadway users that is presented by the lower axial edge(s) of the cargo compartment in the region(s) that are present between the trailer's rear most tires and the trailer's rear under-ride guard and/or between a stationary forward under-ride guard and the trailer's front most tires.
