An apparatus for a single-track motor vehicle includes a first wheel disc and a second wheel disc. The first wheel disc and the second wheel disc are configured on the wheel rim so as to be mutually spaced apart in a transverse direction parallel to the rotation axis (A) of the disc wheel, and extend from the wheel rim in the direction of the wheel hub. The wheel discs converge in the direction of the wheel hub and are connected to one another in such a manner that at least one cavity between the wheel discs and the wheel rim is formed. At least one cutout toward the at least one cavity is formed in a rim well of the wheel rim.

A rim portion of a vehicle wheel has an outer flange portion. In a region of the outer flange portion, a space portion between spoke portions is disposed on a radial-direction inner side, a first inclined surface and a second inclined surface are provided. The first inclined surface is provided on an axial-direction outer side of an outer flange outer circumferential portion. The second inclined surface is on an axial-direction outer side of an outer flange inner circumferential portion. The first inclined surface is formed to incline from the axial-direction outer side toward an axial-direction inner side as the first inclined surface extends from a radial-direction outer side end toward the radial-direction inner side. The second inclined surface is a surface formed to incline from the axial-direction inner side toward the axial-direction outer side as the second inclined surface extends from the radial-direction outer side toward the radial-direction inner side.

A method for making a carbon fiber wheel rim includes: preparing an outer supporting piece; winding a carbon-fiber yarn around the outer supporting piece to form carbon fiber layers and to constitute an engaging seat preform; connecting an inner supporting piece to the engaging seat preform; connecting a reinforcement piece to the inner supporting piece; winding a carbon-fiber yarn around an assembly of the engaging seat preform, the inner supporting piece and the reinforcement piece to form carbon fiber layers; fixing the assembly with the carbon fiber layers to form an outer frame preform; and cutting the outer frame preform and the engaging seat preform to form a trench and removing the outer supporting piece therefrom.

A caster yoke for use in the manufacture of a set of wheeled caster assemblies wherein each caster assembly of the set of caster assemblies is capable of having unique functional capabilities relative to each other caster assembly of the set arising from different combinations of caster components (selected from a set of pre-determined of caster components) being mountable on each respective caster yoke of the set of wheeled caster assemblies. To this end, the caster yoke is provided with all of the mounting features necessary to selectively mount all of the respective caster components of the pre-determined set on the caster yoke, such that the same form of caster yoke may be used without modification as a mounting frame to create a set of caster assemblies having different functionalities, significantly reducing design, production and inventory costs for the set of caster assemblies.

Disclosed are wheel assemblies for motor vehicle powertrains, methods for making and methods for using wheel assemblies, and motor vehicles with wheel units each composed of a tire and a wheel assembly. For example, a multi-hub wheel assembly for a motor vehicle is disclosed. The motor vehicle includes a tire and a suspension component, such as a hub-and-bearing assembly, mounted to the vehicle body. The wheel assembly includes an outer wheel with an annular rim well attached to a central hub. The central hub mounts onto the vehicle's suspension component, e.g., via lugs and bolts, while the tire mounts onto the rim well. The wheel assembly also includes an intermediate hub with a deflection annular rim attached to a mounting base. The mounting base is attached to the outer wheel. The intermediate hub mounts inside a hollow core of the outer wheel, interposed between the central hub and the suspension component.

A hub for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body having axially opposite end portions and a longitudinal central axis. Each of a pair of bearing receiving bores is formed in the cylindrical body at a respective axially opposite end portion of the cylindrical body. A circumferential envelope has an outer diameter and is formed on the cylindrical body about one of the pair of bearing receiving bores. A flange extends radially outward from the cylindrical body at a location between the pair of bearing receiving bores. A barrel portion of the cylindrical body extends between the flange and the circumferential envelope and has an outer diameter. The hub provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion 104.

A method is provided for producing a bicycle wheel made of a fiber composite material, including laminating, in one piece and in one step, a rim, a plurality of spokes each including a first spoke section and a second spoke section, and a center having a first center disc and a second center disc, wherein all fibers for the rim, the spokes, and the center are laid in mold parts in the one step; curing the laminated rim, spokes, and center to form the bicycle wheel; and removing the formed bicycle wheel in said one piece from the mold, wherein the spokes are laminated and cured such that the first spoke section and the second spoke section have a substantially straight shape.

An axle housing assembly for a vehicle is provided. The axle housing assembly for a vehicle includes a first axle housing, a second axle housing spaced apart from the first axle housing in a front-rear direction, an upper connector and a lower connector. The upper connector defines a front end connected to the first axle housing and a rear end connected to the second axle housing, and the lower connector is disposed below the upper connector and defines a front end connected the first axle housing and a rear end connected to the second axle housing. A vehicle including the axle housing assembly is also provided.

The invention relates to a caster for movable objects, and more particularly a bed caster, and at least comprises: a running wheel; a fork receiving said running wheel; a guide tube which is designed to be swivelable relative to the fork via at least one bearing; locking means provided on the fork side; and a braking system which can be brought into operative connection with the running wheel and is designed to block rotation of the wheels, characterised in that the braking system includes a brake shoe, a brake spindle, a guide pin and a cup-shaped guide element, wherein the brake spindle has groove-shaped guides, the cup-shaped guide element is provided with projections, and the projections can be brought into operative connection with the guides of the brake spindle in order to form the anti-rotation means.

A heavy goods vehicle (10) having a vehicle frame (12) and at least one driving axis (A), which has on either longitudinal side (10a) of the vehicle (10) a bogie (22) comprising a wheel assembly (14), each wheel assembly (14) comprising at least two wheels arranged symmetrically in relation to a central axis (S), and a wheel suspension (18) by means of which said wheel assembly is fastened to a rotary plate (28) of the bogie (22), this rotary plate (28) being mounted on a rotary bearing (24) of the bogie (22) which is engaged with the vehicle frame (12) so as to be rotatable about a steering swivel axis (X). According to the invention, the rotary bearing (24) of the bogie (22) can be adjusted in the width direction (B) of the vehicle relative to the vehicle frame (12) and can be detachably connected to the vehicle frame (12) in an operationally stable manner.
