Pentagonal backer plate

Wide body traction stud

Traction stud backer plate

A stud stabilizing, positioning and force distributing member for mounting a stud on the outer face of an endless track which includes a plurality of integrally formed traction lugs that extend outwardly beyond the outer track base. The force distributing member includes a hollow enclosure wall, defining an inwardly opening cavity, having a terminal rim which lies in a predetermined plane for abutting the outer face of the track portion between the traction lugs. The enclosure wall includes an aperture there-through which mounts a traction stud at a rearwardly forwardly inclined angle, relative to the direction of track travel and relative to a line perpendicular to the plane, to dispose the stud on the underside of the lower run of the track at a forwardly outwardly inclined angle relative to the vertical line when the track is not under load and a vertical position when the track is under load to drive a snowmobile.
