This disclosure relates to an attachment for a vehicle wheel which allows the vehicle to be driven with limited tire functions.

A flat tire safety system, having: (a) a pair of elongated semicircular members dimensioned to wrap around a tire rim and be positioned within a tire; and (b) a pair of clamping assemblies, each clamping assembly securing an end of the first elongated semicircular member to the end of the second elongated semicircular member, wherein each clamping assembly has: (i) a housing, (ii) a double-headed bolt passing through the housing, (iii) a tightening bolt mounted in the housing, wherein rotating the tightening bolt turns the double-headed bolt, (iv) a ratchet on the housing for permitting the tightening bolt to rotate in a tightening direction and preventing the tightening bolt from rotating in a loosening direction, (v) a release on the housing for selectively permitting the tightening bolt to rotate in the loosening direction, and (c) a pair of anchors, wherein each anchor is embedded in the end of one of the elongated semicircular members, and wherein one end of the double-headed bolt passes through each of the anchors.

Disclosed are an explosion-proof tire hub, including a hub body and an explosion-proof convex retainer. The hub body includes bent portions configured to mount a vacuum tire, the hub body is provided with a central axis, the explosion-proof convex retainer is fixed on the hub body, the distance between an upper end of the explosion-proof convex retainer and the central axis is L1, the distance between an upper end of the bent portion and the central axis is L2, and L1 is greater than L2. In case of burst or instantaneous pressure loss, because the distance L1 between the upper end of the explosion-proof convex retainer and the central axis is greater than the distance L2 between the upper end of the bent portion and the central axis, the explosion-proof convex retainer reduces the distance between the whole hub and the ground during tire burst and improves safety performance.

A front tire heating and cleaning system for a vehicle includes a brake system configured to selectively apply hydraulic braking pressure against front wheels and rear wheels of the vehicle, and a controller in signal communication with the brake system. The controller is configured to, upon receipt of a request, initiate a controlled front tire heating mode where the brake system is controlled to selectively apply hydraulic braking pressure against the rear wheels and not the front wheels, and rotate the front wheels to increase tire temperature for improved front wheel traction during off-road maneuvers.

A wheel traction surface in the event of a vehicle experiencing a lack of traction during an emergency, while experiencing conditions such as snow, rain, ice, or being stuck in a ditch. The wheel traction surface includes a support surface, wherein the support surface is flat and configured to support a vehicle. The wheel traction surface includes a plurality of securing members configured to grip or drive into a ground surface, wherein the securing members are positioned on a first side of the support surface. The wheel traction surface includes a plurality of studs configured to grip on or more tires of the vehicle, on a second side of the support surface.

A portable escape device is provided for self-rescue in the case of an auto tyre being trapped in a pit. The portable escape device includes support posts, a clamping device fitted to the support posts, and a jacking device fitted to the clamping device. The support posts are fixedly mounted onto spokes. The clamping device clamps an auto tyre. The jacking device protrudes and extends out of a top face of a tyre portion. The portable escape device can release the trapped auto tyre and perform self-rescue fast and reliably, and it is convenient to carry.

An escape device for self-rescue in the case of an auto tyre being trapped in a pit includes a central positioning device, at least one tyre claw and a jacking device. The central positioning device is positioned and mounted at a central position of a wheel. The tyre claw and the central positioning device are fitted to each other and are clamped onto the tyre. The jacking device and the tyre claw are fitted to each other. The jacking device is further provided with a jacking head in contact with the pit ground. The jacking head protrudes out of an external rim of the tyre. The escape device for self-rescue can carry out effective rescue for trapped tyres, is convenient and fast to assemble and disassemble, saves time and energy, improves driving safety, and reduces the occurrence of accidents.

This disclosure relates to a clamping device for tensioning an attachment on a rim of a vehicle wheel, wherein the attachment configured to enable a driving operation with a restricted tire function in an operating state in which it is fastened on the vehicle wheel.

A tractor or trailer axle replacement spindle and seal ring assembly includes a spindle with an elongate cylindrical body having bearing surfaces and threads. The seal ring is a shorter cylindrical component having an opening sized to achieve an interference fit with the spindle. The exterior surface of the spindle and the interior surface of the ring seal include complementary oblique, shoulders bounded by regions of constant diameter. The spindle also includes a shoulder or flange at its end opposite the threads which positively axially locates the seal ring thereon. When the two components are to be assembled, the seal ring is heated to several hundred degrees Fahrenheit and slid onto the spindle until the seal ring contacts the shoulder or flange on the spindle.

An attachment for a vehicle wheel enables driving operation with limited tire function. The attachment includes a base body and a fastening device for fastening the attachment to a rim of the vehicle wheel, wherein the base body, when seen in an axial direction, is circular or annular in shape.
