An auxiliary traction system for imparting auxiliary traction to a vehicle, the system including: a first traction assembly including a first tire and a wheel, the wheel is placed inside the first tire; a second traction assembly including a second tire; a second wheel having a first end connected to the wheel of the first traction assembly and a second end passing through the second tire; the first end of the second wheel has a first flange having a convex shape that fits into a central hole of the wheel; and the second end of the second wheel has a second flange having a concave shape.

A non-pneumatic tire includes a wheel portion, a tread ring portion, a plurality of flexible spokes extending between and attached to the wheel portion and the tread ring portion, and plurality of bump stops positioned between the wheel portion and the tread ring portion. The bumps stops are configured to limit deformation and/or compressive strain of the plurality of flexible spokes. The plurality of bump stops includes a plurality of tower bump stops, a plurality of triangular-shaped bump stops, and/or a plurality of roof-top shaped bump stops.

A quick-release structure has: a shaft lever having a shaft lever external thread at one end thereof and a shaft lever internal thread at the other end thereof; a fixed seat sheathed on the shaft lever in a non-rotatable manner relative to each other. The fixed seat has an annular fixed seat engaging tooth on one end face thereof; a movable seat having an axially penetrating perforation, wherein the movable seat has an annular movable seat engaging tooth on one end face thereof, and the movable seat engaging tooth faces the fixed seat engaging tooth of the fixed seat; a spring abutting between the fixed seat and the movable seat; a spanner rod having a pivoting hole; and a connecting shaft, one end of which abuts on the spanner rod, and the other end of which has a connecting shaft external thread.

A non-metallic rim for a wheel which may be used for motorised vehicles. The rim has a barrel, a first flange, a second flange, a first bead seat, a second beat seat and a primary structural component. The primary structural component extends into at least the first flange and the barrel, and the primary structural component is capable of bearing the majority of the radial and/or lateral load that is borne by the rim during usage. Additionally, the rim has at least a portion of the first bead seat spaced apart from the primary structural component and/or has a protective insert in between the outer face of the first flange and the primary structural component.

A lock nut system includes a nut having a retaining member which includes a keeper having locking teeth configured to engage with the lock nut teeth. The locking teeth are offset in either a clockwise or counterclockwise direction to allow the lock nut to be locked into position on the shaft without further rotation or other adjustment of the nut.

The Lummi Rex, is an advanced car tire that displays contrasting colors within the tire by the aid of the shining chromes found on the rims and it is to yield caution to other drivers and pedestrians. The sole purpose of the Lummi Rex is to reduce and eliminate road accidents due to poor driving, drunk driving, irresponsible drivers, reckless drivers, car malfunctions, broken taillights, and miscommunication between drivers, pedestrians, and everything in its surroundings. The mission of the Lummi Rex is, but not limited to ease the communication process between drivers and pedestrians in a novel manner. Pedestrians will know that when this advanced car tire is illuminating in color Blue it means the car ignition is on, color Red means the car is in motion and finally, when the entire tire is glowing in color Green simply means that the brakes have been applied.

Embodiments of the present disclosure generally relate to double-sided wheel assemblies and methods thereof. In one embodiment, double-sided wheel assembly is provided that may comprise a wheel member comprising a first wheel; a second wheel; and a center member disposed between the first wheel and the second wheel, the first wheel and second wheel adapted to distribute the load of the luggage; a wheel carriage for supporting the wheel member; and a wheel support base adapted to couple with the wheel carriage.

A locking device for releasable locking with a counter body, having a base body, which is connected together with an add-on element and a connection element, and actuation means. One or more slides are fastened to the actuation means, which exert a relative movement to the locking device, whereby the slides are able to be brought into contact with the locking means and these can be transferred into a counter geometry of the counter body. Here, the actuation means remain in their respective position due to the return springs of the locking means and of the tension resulting therefrom as well as of a frictional resistance between locking means and slides. An automatic securing device is provided as secondary securing, designed as a spring-loaded securing bolt for securing the position of the actuation means and prevents unintentional opening of the locking device.

The utility model discloses a wheel nut, including a nut body which the outside surface comprises of multiple identical arc surfaces. The arc surface is protruding outward, and the radius of the arc surface is larger than the circumscribed radius of the outside surface of the nut body. The utility model designs the existing square surface of the outer hexagon feature of the wheel nut as an arc surface, which the contact area between the wheel nut and the sleeve and the loading area of the wheel nut can be increased, and then the deformation and looseness of the wheel nut can be avoided effectively, and therefore the service life of the wheel nut can be improved.
