A floating device for an aerial work platform, comprising a pressure oil source (100), a controller (200), a left floating device, and a right floating device, a chassis (700), and a swing axle (600). The left floating device comprises a left hydraulic cylinder (300), a left balance valve (310), and a left locking device; the right floating device comprises a right hydraulic cylinder (400), a right balance valve (410), and a right locking device; one end of the left hydraulic cylinder (300) and one end of the right hydraulic cylinder (400) are hinged on the chassis (700); the swing axle (600) is hinged with the chassis (700); the other end of the left hydraulic cylinder (300) and the other end of the right hydraulic cylinder (400) are hinged on two opposite ends of the swing axle (600); and the left locking device and the right locking device constitute second-level locking of the left hydraulic cylinder (300) and the right hydraulic cylinder (400), thereby ensuring that the aerial work platform will not tip over due to the sliding of the hydraulic cylinders.

The support beam includes a body part extending along a predetermined direction, and a protruding part protruding from an intermediate portion of the body part in the predetermined direction, in an orthogonal direction orthogonal to the predetermined direction. The body part has an axle housing support portion provided at the intermediate portion, and a pair of suspension member connecting portions provided at one end portion and the other end portion of the body part. The protruding part has a stabilizer member attaching portion. The stabilizer member attaching portion includes a bottom wall portion continuous with the body part and extending along the predetermined direction, a side wall portion continuous with the bottom wall portion and extending along a direction orthogonal to both the predetermined direction and the orthogonal direction, and a top wall portion continuous with the side wall portion and extending to face the bottom wall portion.

The invention relates to an axle unit comprising an axle tube and a link element, wherein the axle tube substantially extends along a tube axis, wherein the link element has a joining portion with a first welding portion and a second welding portion, wherein the link element is arranged with its joining portion adjacent to the axle tube and substantially transversely with respect to the tube axis, wherein, in the first welding portion and in the second welding portion, a welded joint can be produced between the link element and the axle tube.

A wheel for a utility vehicle includes a first attaching face with which the wheel is to be attached to a hub of a vehicle body, and a second attaching face with which the wheel inversed in a vehicle width direction is to be attached to the hub, where the wheel is structured such that the first attaching face is, when attached to the hub, offset outward in the vehicle width direction with respect to a center line in the vehicle width direction of the wheel, and the second attaching face is, when attached to the hub, offset inward in the vehicle width direction with respect to the center line in the vehicle width direction of the wheel.

A portal hub assembly for raising the chassis of a vehicle. The portal hub assembly includes a portal box and a mounting assembly removably attachable to one side of the portal box. The mounting assembly includes a mounting body forged as a unitary body. A bracket assembly including at least one mounting bracket is selectively attachable to the mounting body to allow the mounting assembly to receive a component of the suspension system of a desired vehicle.

A body connection and a method of manufacturing the body connection is disclosed. A body connecting sleeve is formed in two parts from a spacer sleeve arranged in an axle auxiliary frame and from a body connecting sleeve which is coupled only to the upper shell of the axle auxiliary frame and substantially corresponds to the length of the centering extension. The body connecting sleeve is coupled exclusively in a form-fitting manner to the upper shell.

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 transaxle of a rail vehicle includes: a power assembly; an axle body; a running wheel; a guiding frame; a horizontal wheel; and a connecting rod component, including a first transverse pull rod and a second transverse pull rod, where when the rail vehicle turns left, the horizontal wheel cooperates with a rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the left, and when the rail vehicle turns right, the horizontal wheel cooperates with the rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the right.

Provided herein is an auxiliary hybrid system (AHS) that may be configured to provide electrical propulsion to vehicle or increase range to electric vehicles. In some embodiments, a system is disclosed including: at least one energy storage device configured to store power for a vehicle having at least one differential pinion and at least one axle tube; at least one power conversion device; at least one power conversion controller configured to regulate power flow between the at least one energy storage device and the at least one power conversion device; an input device configured to receive input from a user and configured to translate the input into instructions for the power conversion controller; and a drivetrain configured to transmit power between the at least one power conversion device and the vehicle's at least one differential pinion and configured to connect to the vehicle's axle tube.
