A wheel lock for an automobile includes a pin tumbler lock, a cam that engages with the lock, the cam having a tab that protrudes outward therefrom, a coaxially rotatable tubular sleeve that is configured to receive the lock and the cam and that engages with the tab of the cam, the interior of sleeve defining a tab cavity that engages the tab of the cam and having a plurality of sleeve ridges thereon that are distributed and spaced evenly and a coaxially rotatable tubular core that is configured to receive the sleeve and that slidably engages therewith, the exterior of the core having a plurality of core ridges that are distributed and spaced evenly thereon that engage with the sleeve ridges of the sleeve, the interior of the core defining a threaded aperture for permitting the wheel lock to fasten onto a lug bolt.

Provided are: a cap member, which is applicable to a wheel mounting nut and is less likely to deteriorate its appearance even if attachment and removal thereof is repeated; and a method of mounting a wheel using the cap member. A cap member 1 includes: a shaft portion 11 provided with a male thread 11a to be screwed on a base end portion of a female thread 2a of a wheel mounting nut 2; and a cover portion 12 that is integrally formed with a base end of the shaft portion 11 and covers a base end opening of the wheel mounting nut 2. The shaft portion 11 is provided on a distal end thereof with a hexagonal hole 13, which serves as a tool engagement portion.

A screwing tool for an impact wrench for screwing wheel nuts onto and off from a hub body for securing a vehicle wheel, having a main body, which has an open side oriented toward the wheel nuts and which includes a hollow profile. The hollow profile has a tool contour, which is arranged on the open side and can be brought into engagement with a wheel nut contour. At least one peripheral control edge is remote from the open side for releasing a retention element. The control edge has a circular arc region with a constant control edge height h.sub.1 and a cam region with a control edge height h.sub.2 that decreases continuously and then increases again continuously. Height h.sub.1 is equal to h.sub.2 in the respective transition of the circular arc region and the cam region, such that the geometrical shape of an oval is reproduced in cross section.

Lug nut locking systems, including s for securing lug nuts on a wheel of a motor vehicle comprising a frame with ratcheting apertures. In some embodiments, the device has a pair of supports that fit over the wheel's lug bolts and underneath the frame. In other embodiments, the device comprises uniquely configured securing caps that fit over the lug bolts. In still other embodiments, the device comprises a plurality of protective covers that fit over the securing caps.

A system for wheel alignment is provided including adjustments to camber, toe, and thrust. A sleeve is fitted over the spindle of an axle. Rotation of the sleeve relative to the spindle provides for adjustments to wheel alignment while a locking feature such as e.g., a pin, is used to maintain the selected position of the sleeve relative to the spindle. The available positions of the sleeve Crelative to the spindle are predetermined in order to provide for discrete, known adjustments to the alignment of the wheel. Numerous positions can be provided based on the range and magnitude of adjustability selected.

A wheel nut assembly for fixing a wheel to a vehicle hub which includes a wheel nut with an internal thread and an axial body extension on said nut including a first section with an internal set of axial grooves or ribs and a second section containing a second internal screw thread. There is also a wheel stud having an external thread to co-operate with the internal thread of said wheel nut and having an end portion adapted to project beyond the wheel nut which end portion includes axial grooves or ribs on its external surface. An axial retaining cap consists of an upper externally screw threaded first portion which is adapted to engage the second internal screw thread of said body extension of said nut and attached to said first portion a second cap portion having internal grooves or ribs complementary to the external ribs or grooves on said wheel stud adapted to fit over said wheel stud and having external ribs or grooves adapted to engage the internal set of axial grooves or ribs on the first section of said body extension of said wheel nut. The first portion of said retaining cap is able to be rotated so that it moves axially down the internal screw thread of the second section of said body extension of said wheel nut so that the second portion of said cap is pushed down the end of said wheel stud and is held between the external ribs and grooves of the end of said wheel stud and the internal ribs and grooves of the first section of said body extension of said wheel nut.

An improved fastener comprising a fastener body having a tool-engaging portion, a threaded fastening portion and a shroud-receiving body portion, a shroud concentrically mounted on the shroud-receiving body portion, and an intermediate sleeve disposed concentrically between the shroud-receiving body portion and the shroud, the shroud being supported in rotatable relationship with said shroud-receiving body portion such that said shroud will rotate relative to said fastener body under an applied external torque prior to said fastener body rotating when said fastener is engaged with an external structure at a design installation torque.

A system for connecting a wheel rim to a hub flange of a motor vehicle, having a fastener such a threaded nut or bolt, and a tool which engages the fastener in a positive-locking manner in order to tighten or release the fastener. To provide improved protection against theft of wheel rims and tires, the fastener has an annular groove extending axially from an end surface of the fastener, the groove having an annular base and inner and outer sidewalls shaped to form an undercut wider than an opening of the groove, a recess extending axially below the base for receiving a projection of a complementally-shaped key on the tool to allow rotation of the fastener. The undercut prevents an unauthorized person using a mold-making material, from being able to make an imprint of the groove and producing a tool therefrom to release the fastener.

A fastening arrangement for a rim of a wheel on a wheel hub of a wheel carrier of a motor vehicle. The fastening arrangement includes a central screw which, on a fastening portion, has an external thread which engages in an internal thread of a step of the wheel hub. A tensioner produces a force-fitting connection between the wheel hub step and the central screw. A locking arrangement prevents unintentional release of the central screw. The locking arrangement has a carrier member and a blocking member, wherein the blocking member is pretensioned in relation to the carrier member by a locking spring member and is displaceable in the axial direction. The blocking member is arranged captively in the carrier member via securing means.
