Abstract: A vehicle information system has a first load sensor for generating a first load signal based on a first vehicle load. A first position sensor generates a first position signal based on a position of a vehicle axle. A second position sensor generates a second position signal based on a position of a vehicle kingpin. A memory unit stores vehicle optimization data. An evaluation unit is in communication with the first load sensor, the first position sensor, the second position sensor and the memory unit. A general user interface for receiving input is also in communication with the evaluation unit. The evaluation unit makes an evaluation of the first load signal, the first position sensor, the second position signal, and any input and generates a vehicle optimization instruction relating to a distance between the axle and the kingpin.

Abstract: A trailer slider pin control system is provided including a vehicle body and a rail supported along the body. The rails are moveable between a plurality of positions defined by a plurality of holes in the rail. A pin assembly is supported on the vehicle body and includes a pin moveable between unlocked and locked positions. The pin is disposed in the hole locking the rail to the vehicle body in the locked position. Conversely, the rail is free to move along the vehicle body in the unlock position. A sensor senses a location of a portion of the pin assembly, which corresponds to the unlock position. A vehicle speed control device, such as an engine, transmission, or braking system, is actuatable to limit the speed of the vehicle. A controller is connected to the sensor and the vehicle speed control device to actuate the vehicle speed control device to limit the speed of the vehicle in response to the sensors sensing the unlocked position.

Abstract: A trailer suspension slider is provided that includes a suspension bogey. A trailer is supported on the suspension bogey and is longitudinally movable between a plurality of position relative to the suspension bogey. The trailer includes a stop bar to prevent the bogey from sliding out from underneath the trailer during braking if the pins are disengaged. A locking pin mechanism is movable between a locked position in which the locking mechanism couples the suspension bogey and the trailer in one of the plurality of positions and an unlocked position in which the trailer can move relative to the suspension bogey. The suspension bogey may collide violently with the stop bar when braking from a relatively low speed when the pins are unlocked. To this end, an energy absorption device is supported on either the trailer or the suspension bogey. The energy absorption device collapses in response to the stop bar engaging either the energy absorption device or the suspension bogey.

Abstract: A system for connecting a slider to a trailer frame includes a rotatable locking member having a plurality of teeth that engage with a plurality of openings in the trailer from. The locking member is biased by a rotary biasing in a locked position.

Abstract: A mechanism is disclosed for controlling the vertical position of the transport trailer floor of a heavy trailer bearing vehicle having a pivoting air spring suspension system such that the transport trailer floor maintains a fixed position level to an adjacent dock platform when parked for loading or unloading. The mechanism comprises various embodiments of a locking system that disables the pivotal movement of selected pivoting suspension elements in any one of a plurality of possible fixed positions such that the transport trailer floor, when parked, resists downwardly imposed forces and maintains a fixed elevation equal to the elevation of an adjacent loading dock platform.

Abstract: A number of improved ways of connecting a slider to a trailer frame are disclosed. In one general type of solution, a wedge-shaped locking surface is formed on both the slider and the trailer. The wedged surfaces provide a very secure connection. In another general way of describing the embodiments, several of the embodiments have a plurality of locking surfaces which again provide a more secure connection.
