A work vehicle includes an axle frame extending in a left-right direction, a cylinder coupled to the axle frame, and a first supply conduit connected to the cylinder and configured to supply hydraulic fluid to the cylinder. The first supply conduit is fixed to the axle frame.

The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having an increased slope, which means a smaller angular slope level, or a more acute inclination angle between the central vertical axis of the device and the surface upon which it rolls. The slope, or inclination angle of the present improved device is from 62 to 50, or less. As the inclinations angle can be more acute, the object supported on the rolling system, e.g. a luggage case, can be more sloped without having friction between the main ball involving structure and the ground.

A rail-based floor conveyor system, with a floor conveyor with concavely grooved wheels and rails having a surface which, when in contact, dips at least partially into the grooved area of the wheels, thereby producing at least two load-bearing lines during the movement of the floor conveyor, wherein a wheel holder is provided for each wheel, with at least one horizontal axis of rotation for each wheel and a vertical axis of rotation to a bearing connected to the floor conveyor, and wherein the wheels can be moved by drives or manually on the rail, bearing including a first bearing part and a second bearing part, wherein one of the bearing parts has a concave surface section, which is at least partially in contact with a convex surface section of the respective other bearing part, and wherein both bearing parts are movable relative to one another while maintaining contact.

Wheel suspension comprising a frame suitable for connection to a body of a vehicle and comprising a first and second wheel which together define a track width, and wherein the first wheel is connected to the frame via a first set of actuators and wherein the second wheel is connected to the frame via a second set of actuators such that by means of operating the actuators the track width is adjustable between a narrow track, characterized in that the first set of actuators overlaps in the transverse direction of the vehicle with the second set of actuators.

A patient transport apparatus comprises a support structure comprising a base and a patient support surface for supporting a patient and a caster assembly coupled to the base. The caster assembly comprises a wheel assembly. The wheel assembly includes a first edge, a second edge, and a center disposed between the first edge and the second edge. Each of the edges have a lower coefficient of friction than the center. The caster assembly further includes a tilt assembly coupled to the wheel assembly. The tilt assembly is configured to allow the wheel assembly to tilt relative to a floor surface such that at least one of the first and second edges contact the floor surface.

A spindle sleeve and washer for adjusting the camber, toe, or thrust angle of a vehicle wheel to a desired predetermined angle which allows for use of existing hub and spindle assembly without permanent modification to the vehicle.

A system for wheel alignment provides an indexable pair of washers in conjunction with a sleeve having non-concentric inner and outer surfaces that allow for adjustments to camber, toe, and thrust. The system can be retrofitted to existing axle systems using a sleeve that fits over the spindle of the axle. Rotation of the sleeve relative to the spindle provides for adjustment to wheel alignment. The indexable washers can be used to determine the precise amount of adjustment and fix the position of the sleeve once adjusted. The system can be implemented regardless of the circumferential position (i.e. azimuthal orientation) of a keyway or groove on the axle spindle that is typically used to lock the position of the axle nut.

A spindle sleeve and washer for adjusting the camber, toe, or thrust angle of a vehicle wheel to a desired predetermined angle which allows for use of existing hub and spindle assembly without permanent modification to the vehicle.

A tube assembly for a wheelchair frame comprises a tubular member having at least a first portion and a second portion angled relative to the first portion, the first portion configured to be in a seating zone of the wheelchair frame. The second portion is configured to be in a bottom front zone of the wheelchair frame, the tubular member defining a surface concavity in its peripheral surface delimited by a peripheral step, the surface concavity located at a junction between the first portion and the second portion of the tubular member. An interface member has a peripheral contour shaped and sized for the interface member to be received in the surface concavity and contoured at least partially by the peripheral step.

A system of bracket assemblies for a wheelchair comprises a pair of bracket assemblies adapted to be connected to respective sides of a seat frame of the wheelchair. Each of the bracket assemblies has a base adapted to be secured to a seat frame member of the seat frame, an arm adapted to be secured to a backrest frame member of a backrest frame, and a pivot pivotally connecting the base to the arm for rotational movement of the arm relative to the base. One or more blocking mechanism blocks the rotational movement of the arm relative to the base in a use orientation of the backrest frame. A rod having opposed ends connected to the base of the pair of the bracket assemblies for spacing the bracket assemblies away from one another. A rear wheel unit is also provided.
