The inside surfaces of the apertures are flat and the base and top of the link body include beveling to the outside in their central portions. The vertical extent of the ends of the link taper to apices. The link provides enhanced traction for forestry and similar environments.
Description
TITLE OF INVENTION
TIRE CHAIN LINK
FIELD OF THE INVENTION
This invention relates to tire chain links for use with heavy duty vehicles such as for mining and forestry applications.
BACKGROUND OF THE INVENTION
Tire chain link meshes are formed by attaching links to rings so as to interconnect the links and form a mesh pattern. Typically, the links include attachment apertures through which the rings are threaded. Clearance between io the rings and the edges of the apertures allow the links to move about the ring, making the tire chain as a whole flexible and enabling it to be installed on the tire.
However the ability of the links to move about the rings of the tire chain can cause friction between adjacent links and accordingly the links can tend to wear unevenly.
The principal functions of tire chains are to provide protection against tread wear and to enhance traction. When used in the abrasive environments of mines, the design of tire chains tends to be optimized for protection against wear. In other applications, such as forestry, traction enhancement is a more important objective.
The design of tire chains usually involves a trade-off between the two functions.
In applications where wear protection is more important, relatively small pitch lengths (the span between the distal inner edges of the attachment apertures) such as 63 millimeters or 73 millimeters are used, resulting in relatively tight mesh patterns that maximize tread protection. However short pitch lengths and tight meshes increase the likelihood of trapping debris, snow and ice between the

Tire chain links sometimes provide a featureless working surface such as in U.S.

U.S.
Patent No. 5,058,645 to MCiller provides a single V-shaped profiled element;
U.S.
Patent No. 4,357,975 to Baldry provides a plurality of arcuate upstanding plates;
and U.S. Patent No. 6,520,231 to Dohmeler provides a plurality of button studs.
Where studded links are provided, partial rotation of the links about the rings allows the studs to be angled sideways, thereby reducing their effectiveness.

3 SUMMARY OF THE INVENTION
In one of its aspects, the invention comprises a forged tire chain link having a plurality of studs integrally forged into its top surface.
In another aspect, the attachment apertures of the link present flat rather than rounded inner edges to maximize the contact surface with the ring. This feature minimizes the tendency of the link to rotate about the ring, thereby minimizing the angling of the studs away from the traction surface.
A plurality of spaced studs having square cross-sections are forged into the top surface of the link. The square cross-sections present straight surfaces that io enable for reliable traction. In addition, each stud is angled at 45 degrees in relation to the longitudinal axis of the link. This compensates for the 45 degree angle at which the link itself is presented when bound in a chain link pattern to provide a flat gripping surface in relation to the direction of rotation of the tire. In other words, a straight edge (rather than a corner) of each stud is the first part of each stud to contact the ground and the opposing straight edge of each stud is the last part of each stud to leave the ground.
The vertical dimension of the longitudinal ends of the links include a medial apex to minimize the contact surfaces between adjacent links and to thereby limit wear on the links.
The central portion of the base and top of the link is smoothly beveled to a thin base edge to enhance the gripping of the link into the ground.
A pitch length in the range of 100 mm +/- 15 mm along with an open diamond design for the studs provides effective traction, minimizes the build-up of snow and ice between the studs and provides good tread protection.
In another aspect, the invention comprises a tire chain link having an elongated body, two attachment apertures for receiving a linking element, and a plurality of spaced, upstanding studs along the body. The attachment apertures are

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment of the invention is shown in Figs. 1 to 6. The tire chain link 10 according to the preferred embodiment is entirely forged as a single
6 piece, including notably the studs 32, 34, 36 located on the top surface of the link.
The link 10 has a generally elongated body 11 and comprises two attachment apertures 12, 14 located along the longitudinal extent "in of the link. The attachment apertures 12, 14 are separated by a bridge 18 connecting the base 20 to the top portion 22 of the link. The attachment apertures 12, 14 are adapted to receive therethrough a ring or other linking element to form the overall tire chain. For example, ring 23 shown in Fig. 5 passes through aperture 14 of the link 10.
It is contemplated that a single attachment aperture without a bridge may also be provided rather than two attachment apertures, although at the expense of a likely loss of resistance to bending along the vertical medial axis depending on the strength of the material used to form the link 10. In a single aperature embodiment the two rings within the link may also come into contact with one another.
The vertical extent of each of the opposed longitudinal ends 24, 26 of the link body tapers to medial apices 28, 29 to minimize the contact surfaces between adjacent links and to thereby limit wear on the links.
As best appreciated by reference to Fig. 1, the top 30 and bottom 31 interior surfaces of the attachment apertures 12, 14 are flat rather than rounded. This feature minimizes the angling of the link about the ring of the tire chain due to a greater portion of the ring being in contact with the flat surfaces 30, 31 compared to rounded surfaces.
The base 20 and the top 22 of the body are smoothly beveled toward the outer surfaces of the link in the areas below and above the bridge 18 to enhance the traction of the link into the ground. As best seen in Fig. 3, the beveling provide paddle-like edges for gripping the ground.
The link 10 has a generally elongated body 11 and comprises two attachment apertures 12, 14 located along the longitudinal extent "in of the link. The attachment apertures 12, 14 are separated by a bridge 18 connecting the base 20 to the top portion 22 of the link. The attachment apertures 12, 14 are adapted to receive therethrough a ring or other linking element to form the overall tire chain. For example, ring 23 shown in Fig. 5 passes through aperture 14 of the link 10.
It is contemplated that a single attachment aperture without a bridge may also be provided rather than two attachment apertures, although at the expense of a likely loss of resistance to bending along the vertical medial axis depending on the strength of the material used to form the link 10. In a single aperature embodiment the two rings within the link may also come into contact with one another.
The vertical extent of each of the opposed longitudinal ends 24, 26 of the link body tapers to medial apices 28, 29 to minimize the contact surfaces between adjacent links and to thereby limit wear on the links.
As best appreciated by reference to Fig. 1, the top 30 and bottom 31 interior surfaces of the attachment apertures 12, 14 are flat rather than rounded. This feature minimizes the angling of the link about the ring of the tire chain due to a greater portion of the ring being in contact with the flat surfaces 30, 31 compared to rounded surfaces.
The base 20 and the top 22 of the body are smoothly beveled toward the outer surfaces of the link in the areas below and above the bridge 18 to enhance the traction of the link into the ground. As best seen in Fig. 3, the beveling provide paddle-like edges for gripping the ground.
7 The top portion 22 of the link comprises a plurality of upstanding spaced studs 32, 34, 36 having square cross-sections. The studs 32, 34, 36 are integrally forged with the body. The straight edges 38, 40, 42, 44 of the studs provide an improved traction edge for gripping onto objects. As best appreciated by reference to Fig. 4, the studs are angled such that each edge of the stud forms an angle of about 45 degrees to the longitudinal extent "f' of the link.
Referring to Fig. 6, when a tire link mesh is assembled, each tire chain link contains one ring extending through its first aperture and a second ring extending through its second aperture. The links are angled about 45 degrees to the direction of rotation of the tire. Since each edge of the stud is preferably at an angle of about 45 degrees to the longitudinal extent "I" of each link, two opposing stud edges end up being aligned perpendicularly to the direction of travel of the underlying tire thereby enhancing the gripping of the edges onto or into the ground. For example, in Fig. 6, edges 38, 42 are perpendicular to direction of the tire rotation (edges 40, 44 are parallel to the direction of the tire rotation).
While the preferred embodiment illustrated herein shows three studs on each tire chain link, an embodiment using two studs or other numbers of studs is within the scope of the present invention.
The link and the studs may be integrally formed, preferably by forging to avoid zo the weakness of joints that may be caused by welding.
The pitch length of the link, namely the maximum distance between distal inside edges 46, 48 of the attachment apertures 12, 14 respectively is preferably about 100 mm but may range from 85 mm to 115 mm.
The tire chain link of the preferred embodiment provides a combination of advantages that result in a superior tire chain mesh that exhibits enhanced traction and good tread protection as compared to prior art tire chain links and that is notably suitable for applications in forestry and in other environments
