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 anti loosening arrangement doer wheel nuts which uses wheel rim with a plurality of studs having external threads to receive fastening nuts, a wheel nut with an internal thread adapted to be secured to said studs a connector adapted to be attached to and connect adjacent nuts said connector including a mechanism to prevent rotation of the nuts. This arrangement does not require a custom stud. In some preferred mechanisms custom nuts may be needed but in other preferred embodiments conventional nuts may be used. The connector prevents rotation of the nuts and so inhibits loosening. The connector is easily seen and is an indication that the wheel nuts are unable to be loosened.

An apparatus and method for holding a lug nut. The apparatus includes a base (150), a barrel (140), a lug nut engagement assembly (130), a plunger and a cam guide (170). The barrel (140) is coupled with the base (152) in a manner allowing the barrel (140) to move upwardly or downwardly within the base (150). The barrel (140) has an internal cam track portion (145). The lug nut engagement assembly (130) includes retractable fingers (132). The lug nut engagement assembly (130) is removeably affixed to the barrel (140). The plunger (160) is disposed within a portion of the lug nut engagement assembly (130), the barrel (140) and the cam guide (170). The plunger (160) has a tip for engagement with the retractable fingers (132). The cam guide (170) is disposed and moveable within a bottom portion of the barrel (140). The cam guide (170) has longitudinal rails (172) for engagement with the internal cam track (145) of the barrel (140).

A vehicle wheel lock assembly includes a main body and a first sleeve. The main body has a wheel engaging end, a key portion, a first supporting section and a key receiving end. The key portion has a plurality of surface contours defining a first key pattern configured to couple with a tool for torsional movement of the main body. The first sleeve has an open end and a closed end. The open end is installed to the first supporting section of the main body such that the closed end of the first sleeve covers the key receiving end with the key portion exposed relative to the first sleeve. The first sleeve is retained by the first supporting section for rotation about the central axis of the main body and is non-movably retained relative to an axial direction of the main body.

This invention is related to a wheel securing structure of trucks. The securing structure mainly install iron screwshaft liners on keyholes of the mounting parts of the aluminum rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners each. A first folded edge and a second folded edge are formed on two terminals of the screwshaft liners to respectively insert into the conical pits of the mounting part of the rims. The nuts screw onto the bolts of the assembling part to secure the rim onto the assembling part and the nuts. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling part. Therefore, friction is generated between the wheels and the bolts, as well as the nuts and the terminal surfaces of the assembling part. The screwshaft liner is used to let the friction above act on the screwshaft liner. Therefore, the soft aluminum rim will not be directly rubbed by the bolts, nuts, and the assemble part to be damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.

An apparatus (10) for visually indicating a loose wheel nut (57) on a wheel of a motor vehicle has a plurality of wheel nut engaging members (12, 14, 16, 18, 20). Each wheel nut engaging member is rotatable with a respective wheel nut to which it is engaged and has a pointer (26) for indicating a start position of the wheel nut engaging member. Any two adjacent wheel nut engaging members of the plurality are interconnected by an elongate member (28) which is resiliently flexible so as to define an endless configuration of spaced apart but interconnected wheel nut engaging members. In use, any loosening rotation of a first wheel nut (57) will cause the engaging member (12) which engages that wheel nut and its pointer (26) to rotate therewith, thereby providing a visual indication of a loosening of that wheel nut.

A vehicle wheel element structure includes a center disc member, abutment members, and wheel-element-side fastening surfaces. Disc members extend radially in an outer diameter direction from the center disc member. The center disc member includes a center bore and fastening holes. The abutment members are provided on an inner side of the center disc member. Each abutment member protrudes from a position that is away from an opening of a corresponding one of the fastening holes by a predetermined distance. Each abutment member protrudes by a predetermined amount with respect to a reference plane when the abutment member is fastened to a hub unit. The abutment members abut first on a hub-side fastening surface. The wheel-element-side fastening surfaces are provided on the inner side of the center disc member. Each wheel-element-side fastening surface includes the corresponding one of the openings.
