摘要： Versatile four-wheel towable utility carts, systems, devices and methods for transporting loads for agricultural applications, landscape applications, and the like. The carts can be towed by small and large vehicles, tractors, as well as by tractors, all-terrain vehicles (ATVs), golf carts, and the like. The carts can have an X frame with a steerable front end where the front wheels can be steered by the tow bar. Upwardly extending posts on the frame can have C channel ends that can allow for beams, such as wooden boards to be horizontally supported. The user can add a wood deck platform across the horizontal beams to support various heavy loads.

摘要： A control apparatus controls the hydraulic connection between self steering wheels on a trailing vehicle, for example a grain cart, and the hydraulic system of a utility vehicle, for example a tractor, towing the trailing vehicle. An auxiliary circuit on the trailing vehicle forms a continuous loop receiving in series one or more wheel actuators associated with the self steering wheels. A valve arrangement is operable in a locked state or unlocked state in which the continuous loop is isolated from the tractor to prevent or allow a flow of fluid in the continuous loop regardless of the state of the tractor hydraulics. In a manual state, the flow in the loop is dependent upon the tractor hydraulics. In an automatic mode, a controller automatically operates the valve arrangement between the locked and unlocked states dependent upon one or more sensed operating conditions of the trailing vehicle.

摘要： A steering wheel system for a semi-trailer is described. The system uses a retractable encoded system releasably connected to a kingpin, a mechanical steer driving system translating the rotation of the kingpin to a hydraulic system, and a non-circular cogged system driven by the hydraulic system adapted to steer the wheels. A hydraulic generator system powered by the rotation of the wheels is used to decrease the electric energy required by the hydraulic system. Other improvements are also present to increase security, decrease weight and improve time expectancy of the components.

摘要： A heavy-duty vehicle, comprising a steering unit mounted on a vehicle frame of the heavy-duty vehicle, wherein the steering unit is rotatable about an axis of rotation of the steering unit. The heavy-duty vehicle comprises a steering input element connected to the steering unit and configured to cause the steering unit to rotate about the axis of rotation of the steering unit. The steering unit has at least one connecting portion configured to be connected to one or more of a steering device of the heavy-duty vehicle or the steering input element of the heavy-duty vehicle. The steering unit comprises at least one actuating unit configured to change a distance of at least one connecting portion relative to the axis of rotation of the steering unit.

摘要： An air reservoir for a steering axle is mounted on a trailer, the steering axle comprising a pair of rotation pivoting wheel assemblies. Each wheel assembly has a rotation plate and a steering arm connected thereto. A rod pivotally connects the steering arms, each wheel assembly being rotatably connected to either end of the axle. An air stabilizer assembly is mounted on the axle and is connected to the rod, the air stabilizer assembly having an inflatable damper assembly thereon. An air supply is fluidly connected to an air inlet on the axle, the air inlet being fluidly connected to the damper assembly. The air stabilizer assembly dampens pivotal movement of the wheel assemblies when compressed air from the air reservoir fills the damper assembly. The air stabilizer assembly allows the wheel assemblies to rotate more freely when pressure of the compressed air within the damper assembly is reduced.

摘要： An all-wheel steer trailer is disclosed which includes an elongated frame, having a forward end and a rearward end, with the forward end of the frame having the rearward end of an elongated tongue secured thereto about a horizontal axis. The rearward end of the tongue is pivotally secured, about a horizontal axis, to a pair of wheels at the forward end of the frame. The invention includes an improved structure wherein the pivoting of the front wheels of the trailer also causes the pivoting of the rear wheels of the trailer so that the rear wheels track the front wheels of the trailer as the trailer is being turned. The trailer includes an improved means for pivoting the rear wheels of the trailer with respect to the front wheels of the trailer as the trailer is being turned.

摘要： The axle assembly has an elongated shaft that is connected to a mounting bracket. A first end of an arm is connected to the elongated shaft. The arm extends rearwardly from the elongated shaft and connects to a bearing bracket at a second end. The bearing bracket has a pair of flanges and a pin that passes through the flanges and is received within an opening of a rotatable arm. The rotatable arm is connected to an axle.
