Disclosed is a portable escape device for self-rescue in the case of an auto tyre being trapped in a pit, comprising 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 for self-rescue in the case of an auto tyre being trapped in a pit can release the trapped auto tyre and perform self-rescue fast and reliably, and is convenient to carry.

A traction aid apparatus for a motor vehicle wheel. The apparatus has an elongated main body; a first securing member located at the first end or near the first end of the elongated main body and projecting downwardly comprising a surface for engaging a first side wall of the motor vehicle tire; a second securing member projecting from the elongated main body comprising a surface for engaging a second side wall of the motor vehicle tire opposite the first side wall of the motor vehicle tire, a tension mechanism connected to the elongated main body or the second securing member; and a flexible wheel engaging member that is configured to pass through an aperture in the motor vehicle wheel to the tension mechanism to secure the traction aid apparatus to the motor vehicle wheel.

The anti slip device for automobile wheels with wheel discs arranged at inner side plain of the wheel, load-bearing part of which is attachable to the wheel from the outside. The extensible body is placed slidingly in the direction parallel to the wheel axis on the load-bearing part. There are arms fulcrumed on the extensible body around axes parallel to the wheel axis. The arms are fitted, at their ends, with surfaces of engagement, which bear against the tire peripheral surface in the working position. The extensible body is placed on the load-bearing part in the guidance, which comprises at least two pipes, with one outer pipe placed slidingly on each of the pipes and attached to the extensible body. There are tensile springs arranged in the pipes, and these springs are attached by one end to the load bearing part, and by the other end to the extensible body.

A traction aid for a motor vehicle, comprising an elongated main body having a top and a bottom surfaces, the elongated main body having thereon a series of teeth and a sliding mechanism, a first securing member located at an end of the main body and projecting downwardly and a second securing member located at the bottom surface of the main body and attached to the sliding mechanism. The sliding mechanism allows movement of the second securing member towards or away from the first securing member along the bottom surface of the main body. The traction aid further comprises a securing mechanism configured to move the sliding mechanism and the second securing member towards the first securing member in order to squeeze a tire of the motor vehicle between the first and second securing members.

A track attachment includes a track body forming a convex surface for facing a driving terrain and a concave surface for facing a wheel or tire, with at least one blade extending from the convex surface for increasing lateral traction of the wheel or tire. The at least one blade may be defined as an elongated shape extending in the direction of rotation of the wheel or tire to generate and increase in lateral traction. The track body and at least two blades may define a channel at the convex surface to generate a floating effect on soft and loose terrain. The track attachment may be provided with supporting ribs and openings for facilitating attachment to the wheel or tire. A traction system includes a plurality of track attachments secured to a wheel or tire.
