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.

A caster device includes a caster wheel configured to rotate around a horizontal rotation axis; and a case configured to expose a lower surface of the caster wheel, cover the caster wheel and have an inclined surface from a top of the horizontal rotation axis toward a bottom of the horizontal rotation axis.

A wheel caster comprising a roller, and a two piece socket, wherein the two piece socket comprises a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, a stem, to be inserted inside a leg of an object, and a bottom housing comprising an opening to allow a portion of the roller to extend below the bottom housing allowing the roller to contact a surface.

A vehicle includes a vehicle body, at least one wheel includes an annular tire that rotates to drive the vehicle body along a main driving direction, a wheel gear disposed on an inner surface of the tire, and an in-wheel actuator that is connected to the wheel gear and that rotates to rotate the tire, and positioning devices that are fixed to the vehicle body and that rotate the at least one wheel relative to the vehicle body to change positions of the at least one wheel relative to the vehicle body, the at least one wheel being coupled to at least one positioning device so as to be rotatable.

A tire traction assembly for enhancing traction of vehicle tires on a slippery driving surface includes a pair of traction frames that can each be positioned on a slippery driving surface upon which a vehicle is not capable of driving due to a loss of traction. A plurality of nets is each integrated into a respective one of the traction frames. The plurality of nets includes a set of top nets and a set of bottom nets. Moreover, each of the set of top nets frictionally engages a respective vehicle tire and each of the bottom nets frictionally engages the slippery driving surface when the traction frames are positioned on the slippery driving surface. Additionally, each of the top nets and each of the bottom nets is comprised of a resilient material to resist being deformed by the weight of the vehicle tire.

An adaptable wheel has a central hub, radial segments connected to the central hub at a proximal end and extending radially from the central hub, each radial segment having a linear actuator configured to change a length of the radial segment; a shoe connected to a distal end of the radial segment for contacting a surface being traversed by the wheel; and a locking mechanism for selectively preventing linear motion of the linear actuator. A control system for an adaptable wheel includes a distance sensor on a vehicle for determining distance to a surface in the path of the vehicle and a computer for receiving distance information from the distance sensor and, responsive to the distance information, determine a desired length of a segment of an adaptable wheel for maintaining a hub of a wheel level, and provide control signals to a linear actuator of the segment.

A vehicle traction mat in the form of an elongated body member having a top surface with protruding upright gripper members or cleats for engagement by a vehicle wheel or tire includes a storage receptacle with a removable cover intercepting the top surface of the elongated body member, and further includes a reinforcing insert member adapted to be placed into the storage receptacle after removal of the cover and fastened in place to the elongated body member to provide enhanced stiffness and strength to the vehicle traction mat.

An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel and on which the weight plate is guided in a longitudinally axial manner. A clamping lever closure is disposed between the weight plate and retention member. A first assembly element of the clamping lever closure is coupled to the retention member, a second assembly element of the clamping lever closure engages the weight plate in a longitudinally axial manner, and a lever mechanism is disposed between the first and second assembly elements. The lever mechanism includes a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element.

A low impact turf wheel having a wheel rim including an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the plurality of pegs maintain the wheel rim above an area of turf, and a hub. A turf wheel having a wheel rim having an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the peg comprises a stem, a collar and a lug, and wherein the lug includes a limited surface area to provide a ground contacting tread, and a hub.

A vehicle traction mat for use to extricate a vehicle stuck on a slippery road surface is provided. The traction mat comprises at least a main mat segment having a plurality of surface cleats, knobs, and knob cleats on a road-facing surface thereof. The cleats and knobs provide traction between the traction mat and the slippery surface. The traction mat may be provided with edge mat segments foldably connected to opposite ends of the main mat segment. The traction mat may have cleats, knobs, and knob cleats on the tire-facing surface thereof.
