A trailer system for hauling material. The trailer system including a frame and a container attached to the frame. A lid is operatively associated with a first aperture and adapted to at least move between an open position and a closed position. When in the closed position the lid seals the first aperture such that the seal is watertight. A gate is operatively associated with a second aperture and adapted to at least move between an open position and a closed position. When in the closed position the gate seals the second aperture such that the seal is watertight. A pusher plate assembly is arranged with the container for pushing material contained in the container in a direction towards the second aperture.

A load sensor having a centrally disposed aperture element through which a fastening element of a vehicle air suspension assembly passes to affix the load sensor between the vehicle air suspension assembly and the vehicle suspension, wherein the load sensor has a force measurement sensor disposed proximate an elongate slot to generate a load signal which varies based on an amount of strain in the load sensor, wherein the load signal received by a load calculator allows calculation of the load exerted from the vehicle frame to the vehicle suspension.

An emergency egress system for a multi-passenger vehicle such as a school bus (10) includes a housing (30) that operatively supports a ramp (34) in movable connection therewith. Opening an emergency exit door (18) of the bus causes a housing door (24) to open and the ramp to move outwardly from a retracted position toward an extended position. Opening the emergency exit door also causes the suspension of the bus to be automatically lowered to place the emergency exit opening (16) closer to the ground (166).

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

In a method for determining an axle load on a mechanically and/or pneumatically/hydraulically suspended vehicle, the axle load is determined with the aid of control and sensor means that are installed in the vehicle and/or functionally enhanced. Functions for axle load determination at mechanically suspended vehicle axles (4) and for axle load determination at pneumatically/hydraulically suspended vehicle axles (2) are available. In a mechanically suspended vehicle axle (4) a distance measuring unit (9), and in a pneumatically/hydraulically suspended vehicle axle (2) a pressure measuring unit (7) are used to determine the axle load. An initial plausibility check is implemented in an electronic control unit (10) of the level control system (1), on the basis of which the level control system (1) identifies the particular suspension type, mechanical or pneumatic/hydraulic, of a vehicle axle (2, 4) and, thereafter, the appropriate function for axle load determination is activated.

A shock absorber for a vehicle, the shock absorber having an absorber body with an outer surface, and a movable piston having a first end configured to couple with the vehicle, and a second end disposed within the absorber body. There is a magnet assembly disposed around and external of the movable piston at the second end. The absorber has a sensor assembly having a sensor body coupled with the outer surface. An inner sensor body has a sensor disposed therein configured to detect a change in a linear position of the magnet assembly.

The invention relates to an article, more particularly an air spring bellows, having a one-layer or multi-layer main body with elastic properties, at least one layer of the main body being made up of a rubber mixture, a carbon black proportion of at least one carbon black, more particularly a total carbon black proportion of all carbon blacks, of the rubber mixture being less than 5 phr. The rubber mixture preferably contains aluminium hydroxide as a reinforcing filler. The rubber mixture can comprise chloroprene rubber as a base polymer.

A throttle assembly for a pressure control system in a vehicle includes at least one throttle valve. The at least one throttle valve defines an assembly cross-section of the throttle assembly, the assembly cross-section specifies a flow resistance acting on a pressure medium entering the throttle assembly, and the at least one throttle valve includes at least one controllable throttle valve configured to be controlled in accordance with an upstream pressure. The assembly cross-section of the throttle assembly is configured to be set, by control of the at least one controllable throttle valve, in such a way that an inlet volume flow of the pressure medium entering the throttle assembly can be limited to a limit volume flow in accordance with the upstream pressure, in order to set, in accordance with the upstream pressure, a power consumption of a pneumatic load in the pressure control system.

A suspension component for a vehicle may include a spring section performing a support function for supporting a portion of the vehicle and a shock absorbing section performing a damping function to damp action of the spring section. The spring section may be adjustable to provide adjustable support characteristics and the shock absorbing section is adjustable to provide adjustable damping characteristics. The spring section may be adjustable independent of the shock absorbing section. The spring section of the suspension component may define a gas chamber for holding a quantity of a gas to provide a spring support for the vehicle, and the shock absorbing section of the suspension component may define a fluid chamber to provide damping of movement of the spring section.

A bearing device for mounting an axle guide for commercial vehicles includes a first connector which has an axial direction of extension, and a first axial centre in the axial direction of extension, a damping unit, having an outwardly peripheral retaining surface, and a second connector being fixed to the retaining surface, wherein the second connector extends along the axial direction of extension, wherein the second connector has a boundary surface on which an axle guide can be fixed, wherein the boundary surface has a second axial centre in the axial direction of extension, and wherein the first and the second axial centre are offset from each other along a vector of the axial direction of extension.
