A method for providing motor vehicle wheels made of composite material based on carbon fiber includes the steps of, dividing each wheel into a plurality of portions having small dimensions; providing a a first portion with the terminal edges designed to mate with corresponding edges of a respective second portion; mating the portions, arranging them subsequently within a respective mold whose shape and dimensions are conjugate with respect to those of the wheel to be manufactured; and bringing the mold and its contents to a predefined temperature. The method further includes injecting into the mold a resin in the liquid state, the resin being injected at high pressure and high temperature, forming the matrix of the composite that constitutes the wheel; maintaining the pressure and temperature of the mold within predefined ranges for a time interval that is required for the at least partial cross-linking of the resin; and extracting the wheel from the mold.

A marked wheel rim is provided, including: a rim body and a mark. The rim body includes an outer surface. The mark is embedded on the outer surface and includes an outer peripheral edge adjacent to the rim body. The outer peripheral edge is non-protrusive beyond the outer surface. A method for manufacturing the marked wheel rim is further provided.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

A drive axle shaft and method for making the same are provided. The drive axle shaft includes an elongate tubular body and a wheel flange. The elongate tubular body has a longitudinal axis and comprises a first end portion and a second end. The second end is configured to be coupled to a side gear in a differential. The wheel flange is disposed at the first end portion and is configured to support a vehicle wheel. The elongate tubular body and the wheel flange are formed as a unitary body without any weld therebetween.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

The production method includes a first step, a second step and a third step. In the first step, a steel material is forged by dies, whereby a forged product including a rough web part and four plate-shaped rough flange parts is produced. In the second step, at least one specified rough flange part, which is at least one of the four rough flange parts, is pressed by a first die, whereby a first bent portion bending outward in an up-down direction is formed in the specified rough flange part. In the third step, the edge of the first bent portion is pressed by a second die inward in the up-down direction, whereby the edge is deformed and a second bent portion is formed. In the third step, the edge of the specified flange part is deformed while the edge is kept from deforming in a front-rear direction.

A castor suspension system for suspending a first castor at a patient support device is provided. The castor suspension system comprises a pivoting suspension link pivotably attachable to the patient support device, and a springy element comprising a leaf spring made of a band deformed such that the band makes at least one U-turn so that the band has a first leg and at least one second leg. One of the first leg and the at least one second leg is provided with a first support portion supported on the pivoting suspension link, and the other of the first leg and the at least one second leg is provided with a second support portion for supporting the springy element with respect to the patient support device such that the springy element is configured to provide a pre-stress force to the pivoting suspension link.

A wheel width direction (Y) cross-section of a well portion (11A) includes a hump portion (H1) and a hump portion (H2) that protrude to the outside (Z1) in a wheel radial direction (Z), and a curved surface (11s) that connects hump portion (H1) and hump portion (H2) and is sunken to the inside (Z2) in the wheel radial direction (Z). The curved surface (11s) is formed as a series of circular arcs (11e, 11f, 11g) that have centers of curvature (O1, O2, O3) that are further to the outside (Z1) in the wheel radial direction (Z) than the curved surface (11s).

A method for attaching a clamping assembly to the frame of a machine includes attaching a sensor assembly to the spindle of a machine such that a wire harness extends through the internal cavity of the spindle and out from the spindle, fishing the wire harness through a breather line, and attaching the wiring harness to the chassis of a machine.

The invention concerns an axle unit comprising a stub axle and a tube unit, wherein the stub axle at least in regions is configured rotationally symmetrically about a stub axis and has a channel which extends substantially parallel to the stub axis, wherein the tube unit is configured as a hollow body and extends substantially along a tube axis, wherein the tube unit has a recess running transversely to the tube axis, wherein a line element is provided which can be brought into fluid-tight connection with the channel and passed through the recess of the tube unit. A method for production of an axle unit is also given.
