The invention relates to a lifting device for lifting loads, vehicles, or the like, comprising a mobile base frame (12); a lifting column (14) provided on the base frame (12); a support (15), said lifting column (14) and support (15) being guided by a guide (45); a load receiving means (20) which is arranged on the support (15) and by means of which a load receiving region (21) is determined, said base frame (12) having at least three support points outside of the load receiving region (21) of the load receiving means (20); and a drive unit which can be controlled by a controller and which moves the support (14) up and down relative to the lifting column (14). The lifting column (14) is arranged on the base frame (12) eccentrically to the load receiving region (21) and in a rotated manner relative to a longitudinal side of the load receiving region (20).

A hollow wheel assembly of a luggage includes a wheel mount, two wheel members, and a hollow shaft. The wheel mount has a shaft sleeve, in which the hollow shaft is received. The wheel members are connected to opposite ends of the hollow shaft for free rotation. The hollow shaft has a vision passage, and the wheel members have a plurality of vision bores, whereby one may see through the wheel members via the vision bores and the vision passages when the wheel members are rotating.

The present invention regards a group for supporting and tightening a rim of or for a tired wheel, and such group includes a base, a wheel-holder table, an upright or column projecting upward from the base and supporting at the top the wheel-holder table, a shaft or pin mounted in or alongside the upright or column, a sleeve element or ring nut element constrainable or mountable on the shaft or pin and means for the relative movement of the shaft or pin and of the table.

A tool for working in fields includes a first flange and a second flange which mount one on the other, forming a wheel body. The first flange includes a central portion, a generally annular peripheral portion and at least one arm which connect(s) the central portion and the peripheral portion to each other. The second flange is homologous to the peripheral portion of the first flange. In the assembled state, the wheel body has a rim which is formed together by the peripheral portion of the first flange and the second flange and a hub which is formed by the central portion of the first flange.

A structurally supported tire includes a ground contacting annular tread portion; a shear band, and a connected spoke disk connected to the shear band. The connected spoke disk has two or more circumferential spokes joined together by a connecting web, wherein the spring rate of the connected spoke disk is greater than the spring rate of the shear band.

A vehicle spindle and a method of attaching the spindle to a portion of an axle half shaft housing. The spindle has an inner surface, an outer surface, one or more bearing journals on the outer surface of the spindle and a radially protruding portion circumferentially extending from at least a portion of the outer surface of an axially inboard end portion of the spindle. Prior to attaching the spindle to the axle half shaft housing, the one or more bearing journals are ground, a clocking angle for the radially protruding portion of the spindle is determined and the spindle is aligned to the determined clocking angle. Once the spindle is aligned to the determined clocking angle, the axially inboard end portion of the spindle is attached to an axially outboard end portion of the axle half shaft housing using one or more welds.

Bearing for at least one supporting roller of a carriage, which supporting roller is supported on at least one bearing surface, comprising at least one axle device which can be rotated about at least one rotational axis, at least one rocker which is connected to the axle device such that it is reliably driven, wherein, at an end which lies opposite the axle device, the rocker has at least one first connecting device for connecting the rocker to the supporting roller, at least one spring device which is arranged mechanically between the axle device and/or the rocker on one side and at least one holding device on the other side, wherein a force which forces the supporting roller onto the bearing surface can be built up on the axle device and the rocker by means of the spring device, and at least one damping device, by means of which a rotational movement of the axle device about the rotational axis can be damped, characterized in that the spring device and the damping device are configured in one piece at least in regions by way of at least one torsion spring element which is of rubber-elastic configuration at least in regions.

A wheel hub transmission unit for a drive wheel of a vehicle is provided. The wheel hub transmission unit includes a wheel axle, a pinion hub carrier concentrically arranged with respect to the wheel axle, a pinion mounted in a torsionally rigid manner onto said pinion hub carrier and configured to drive the drive wheel, and a torque transmission device having a transmission sleeve. The transmission sleeve is made from a magnetically coded material and includes a measuring area that is utilized to measure a torque by utilizing magnetic properties of the magnetically coded material of the transmission sleeve. An annular space is radially provided between the transmission sleeve and the wheel axle in the measuring area with a sensor coil being accommodated therein, the annular space being axially accessible from outside the transmission sleeve.

A hollow wheel assembly of a luggage includes a wheel mount, two wheel members, and a hollow shaft. The wheel mount has a shaft sleeve, in which the hollow shaft is received. The wheel members are connected to opposite ends of the hollow shaft for free rotation. The hollow shaft has a vision passage, and the wheel members have a plurality of vision bores, whereby one may see through the wheel members via the vision bores and the vision passages when the wheel members are rotating.

A frame (10) for a creeper includes spaced side rails (11) having a generally flat top surface (12) and a generally flat bottom surface (13). Opposed arcuate surfaces (14) extend between the ends of the top (12) and bottom (13) surfaces to form a generally oval profile for the side rails (11). A plurality of caster assemblies (15, 16, 17) each include a generally flat mounting plate (36) which is positioned adjacent to, and attached to, the flat bottom surface (13) of the side rails (11). A plurality of crossrails (23, 24, 25, 26) extend between the side rails (11) and are adapted to receive a pad.
