A traction point for a snowmobile track includes a fastener that extends through the track with a head on one side of the track, and a pointed nut that has a pointed end and which is threaded onto the fastener on the opposite side of the track from the fastener head. The traction point includes a base for support on the track, and pyramidal shaped reinforcement gussets that merge at a point to provide for increased traction for the snowmobile. Small ribs can be provided on the traction point for engaging the track to reduce the likelihood of the traction point unthreading and coming off during use. The pyramid shaped flanges give a paddle effect as they engage ice or snow to provide increased surface area for reaction of the driving forces from a snowmobile transmitted through the track, and also increased corner traction and braking effect.
An apparatus for increasing the traction capability of a track driven vehicle comprising:
A traction point for a snowmobile track comprising a base defining a support face, a hub supported on the base and having a threaded bore opening through the base for receiving a fastener, and at least three traction drive members fixed to the base at spaced positions on the same side thereof as the hub, and tapering outwardly away from the base in the direction of the hub toward a center axis of the hub, the traction drive members being adjacent and forming a point at outer ends thereof.
A traction point for a snowmobile track comprising a base, a hub supported on the base and having a threaded bore opening through the base for receiving a fastener, and a plurality of at least four flat blade gusset members fixed to the base and tapering outwardly from the base on a side of the base the same as the hub toward a central axis of the hub, the flat blades being oriented so flat sides thereof are parallel to radial planes passing through the central axis of the hub, the flat blades being secured together at outer ends.
