A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a rear wheel assembly, a front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position. At least one of the wheel assemblies is powered by a selectively engageable drive assembly including a motor, transmission, driveshaft, selectively engageable clutch and hub, to drive the rotation of at least one of the wheels.

A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a steerable rear wheel assembly, a steerable front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

A vehicle stabilization system including a frame; a wheel; a control arm connected to the frame and the wheel; a fluid spring connected to the frame and the control arm; a stabilizer connected to the frame and operable between a retracted and extended position; a reservoir; and a fluid manifold connected to the fluid spring and the chamber, fluidly coupling the spring interior and stabilizer chamber to the reservoir interior. A vehicle stabilization method including maintaining an orientation of the vehicle frame, coupling the frame to a support surface using a stabilizer by introducing a fluid to a chamber of the stabilizer, and retracting a wheel by reducing a quantity of fluid within a fluid spring coupling the wheel to the frame.

A transporting device for launching and hauling boats is provided. The device includes a frame arranged to support a boat hull and is provided with at least two pairs of wheels. Each pair of wheels is formed by two wheels aligned with each other on opposite sides of the frame, and the frame is further provided with one or more tracks. The device is capable of easily and effectively moving both on roads and other hard terrains, and on soft terrains, such as for instance sandy or muddy terrains. According to an embodiment, the wheels and the tracks are mounted on the frame so as to be movable in a direction perpendicular to the plane of the frame itself so that they can be selectively brought into contact with the underlying ground or moved away from ground depending on the kind of terrain on which the device is moving.

The invention relates to an axle assembly of a heavy goods vehicle, comprising a pivot bearing steering rotational axis (X), a wheel support comprising at least one wheel that is mounted thereon so as to be rotatable about a wheel rotational axis (Z), the wheel rotational axis (Z) being arranged behind the steering rotational axis (X), in the travel direction (V), in every deflection state of the axle assembly, during straight travel, and a unit that is adjustable about the steering rotational axis (X) when the wheel support is rotated, the adjustable unit being adjustable between two operating states, specifically a forwards travel operating state in which it damps the rotational movement of the wheel support about the steering rotational axis (X), and a reverse travel operating state in which it introduces a steering force, which steers the axle assembly, into the axle assembly.

An agricultural system includes a controller having a memory and a processor. The controller is configured to determine a steering angle of a work vehicle of the agricultural system, determine a target height of a ground engaging tool of the agricultural system based on the steering angle, and output a signal to control a height of the ground engaging tool relative to a soil surface based on the target height.

Example techniques have been presented for providing tracked vehicles with deployable towing wheels. Such techniques involve a track vehicle having a vehicle body, a track coupled to the vehicle body, and a wheel assembly coupled to the vehicle body. The wheel assembly includes a wheel and is operable to assume a towing position in which at least a portion of the wheel extends below the track and enables the tracked vehicle to be towed on the wheel without the track making ground contact.

A trailer having a plurality of elongate floor members, each of the floor members connected to an adjacent floor member to define a floor of the trailer, side wall members attached to opposed sides of the floor, an axle assembly attached to the side wall members, and a tongue assembly attached to the side wall members.

Axle load detection system for a commercial vehicle includes a force transmission element and a sensor unit, wherein the sensor unit includes at least one sensor, wherein the force transmission element includes a first assembly area and a second assembly area, wherein the first assembly area is fixed or can be fixed indirectly and/or directly to a vehicle frame of a vehicle of a commercial vehicle, wherein an air spring and/or a control arm is arranged and/or configured to be arranged on the second assembly area, wherein the sensor unit is configured to determine and/or detect a force transmitted via the force transmission element between the first assembly area and the second assembly area in a supporting direction.
