The present invention relates to a novel and easy to use tire traction-enhancing tool that is used for increasing traction of a tire stuck in snow, ice, mud and/or other environmental hazards that prohibit or obstruct movement of a vehicle. The tool features a plurality of steel or aluminum chains welded together in a mat or rectilinear configuration that is configured to be securely deployed underneath a stuck vehicle tire. The chains are formed of pre-bent welded links and the chains are connected to each other through connecting links. The tool is lightweight, portable, easy to deploy and remove and can be stored in the trunk of the vehicle. The tool is not required to be mounted to the tire and thus increases the life of the tire and the effectiveness of traction provided to the tire.

A chain for mounting on a vehicle tire, in particular a sliding block chain, having a chain mesh, which is disposed at least on the tread of a vehicle tire in the mounted state of the chain and has a number of chain strands, each of which is formed by a number of chain links each with essentially straight longitudinal legs which run parallel to one another and are connected to one another at their ends by connecting elements in particular connecting rings. In the mounted state of the chain, the chain links of the chain strands lie on the tread at alternately positive and negative angles with respect to the tread. Wear elements are provided, realized as wear webs, which are fixedly connected to chain links of the chain mesh and which extend parallel to the longitudinal legs of the chain links.

The invention relates to an anti-skid chain (1) for tires (3), in particular for bogie axles, wherein the anti-skid chain (1) has two laterally stable guide chains (5) which, when installed, are arranged to the side of the treads (9) of the tires (3), wherein the anti-skid chain (1) has a flexible chain mesh (7) which extends between the two guide chains (5), and wherein at least one guide chain (5) has chain links (15, 17) which are interconnected in an articulated manner by means of joint pins (19) in the circumferential direction (U), and at least one rotation-blocking element (27) by means of which a maximum joint angle (35) between two interconnected chain links (15, 17) is a defined. In order to prevent lateral pulling of the anti-skid chain (1) and, at the same time, to provide an anti-skid chain (1) that is easy to produce, according to the invention, a part of the rotation-blocking element (27) is located on at least one of the joint pins (19).

An anti fall-off cable chain includes two side ropes, a transition chains and connecting pieces, wherein the two side ropes are arranged horizontally, the transition chains are longitudinally arranged between the two side ropes, and the side ropes and the transition chains are connected through the connecting pieces. Each connecting piece includes an attaching part to be attached to a side face of a tire, a side rope mounting part arranged at one end of the attaching part, and a transition chain mounting part arranged at another end of the attaching part. When pulled by the part, attached to the tread of the tire, of the transition chain to tilt upwards, the transition chain connecting pieces trend to draw away from the mounting holes and are limited by first upper limiting parts.

A tire traction assembly for mounting upon a tire. The assembly includes a plurality of flexible members such as chains or cables engaged in pivoting connections with brackets at opposing ends. A separable adjustable connector such as a toothed member is attached to a first of the two brackets and configured for engagement with a ratchet mechanism attached to the second of the brackets to releasably secure the tire traction assembly around the tire. A plurality of traction cables configured to traverse the rolling surface of the tire are located in-between the brackets. The brackets may include a planar tread plate which has opposing planar side surfaces configuring the brackets to a U-shape.

An automotive tire non-skid device for snowfields to increase adhesion to pavement covered with ice or snow, in particular to a diagonal bead chain stress reducing pinch plate and a diagonal bead chain. Through configuration of stress reducing pinch plates and stress reducing transition chains disposed on two sides of a second connecting assembly, concentrated stress at the connector roots of steel cables of the stress reducing transition chains are isolated, dispersed and relieved, and the service life of the steel cables are prolonged. At the same time, the present invention has the advantages of simple structure, stable performance, convenient modification and low manufacturing cost.

The present disclosure relates to a device for increasing traction, and, in particular, to a device to be fitted on a tire or wheel for increasing, enhancing, or improving, the traction, or friction, between the tire or wheel and a surface that the tire or wheel is in contact with. The device comprises two or more line structures, at least two of which configured for encircling along two sidewalls of the tire, respectively. The device further comprises a plurality of cross members configured for contacting a tread portion of the tire, the cross members comprising mechanism for connecting the two or more line structures together. At least one of the cross members comprises a strap made of a material comprising textile, one or more traction components attached to at least a surface side of the strap. The present disclosure further provides a strap suitable for use in the device.
