A vehicle wheel includes: a well portion having an outer peripheral surface on which a vertical wall extending in a circumferential direction of the vehicle wheel is formed; and a Helmholtz resonator attached to a side surface of the vertical wall and to the outer peripheral surface of the well portion with an adhesive.

A wheel cover includes: a cover body having an engagement hole and configured to cover a design face of a wheel; and a cover fastener that is inserted through the engagement hole. A primary attachment member of the cover fastener includes: a supporter that supports a periphery of the engagement hole; a cylindrical portion that is inserted in a hub hole formed in the wheel; a coupler that couples the supporter and the cylindrical portion; and a hook extending from the cylindrical portion to an outer circumferential side of the cylindrical portion, the hook being contactable with an inner circumferential portion of the hub hole at a position spaced apart from an outer circumferential surface of the cylindrical portion. A secondary attachment member of the cover fastener has an insertion portion that is inserted in a space formed between the hook and the outer circumferential surface.

A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

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 wheel lug nut locking attachment, lug nut position locator device, or lug nut locking device is provided, wherein the attachment or devices include a thermochromic material which provides an indication of excess heat generation in the wheel assembly of a tractor trailer. A warning system to alert an operator of the present of excess heat in the wheel assembly is provided. In a preferred embodiment, the device also acts to lock a wheel lug nut to an adjacent wheel lug nut, so as to prevent or reduce rotation of the wheel lug nut. A plurality of thermochromic lug nut locking devices can be fitted to a single wheel so that all of the lug nuts are operatively locked to an adjacent lug nut. The resulting locking system can be rapidly installed on each lug nut on all wheels, so as to provide improved vehicle safety aspects.

A wheel cover unit for front wheels of trucks or buses includes a wheel cover, two attaching members and a cover. The wheel cover is provided with an outer convex platform having a central hole, and the periphery of the central hole is annularly provided with a plurality of nut convex covers and a plurality of through holes. The inner edge of the central hole is vertically and backwardly provided with a hole ring having corresponding two pairs of slots, wherein each slot extends to the central hole with a lock tab. Each attaching member is provided with a connecting portion and two connecting pieces. The connecting portion is locked with the bolt of the wheel and the connecting piece is locked with the lock tab via a screwed element, so as to assemble the wheel cover to the front wheel of the truck or bus.

A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

A system for counting wheel revolutions made by a wheel of a vehicle, the system including an electronic counter, a transmitter, a housing, and a connector. The electronic counter counts a number of wheel revolutions made by the wheel. The transmitter transmits data from the electronic counter to a remote database. The housing houses the electronic counter. The connector removably attaches the housing to a nut anti-loosening device installed on the wheel.
