Abstract
A snow lubrication device attaches to a vehicle body of a snowmobile and includes a pair of snow rake rods extending from the vehicle body to contact a snow surface. A snow rake member located at the end of the snow rake rod scatters snow. The scattered snow lubricates gaps between a track belt and the slide rail and/or between the track belt and the drive wheel. The lubrication of the track belt improves operation of the snowmobile if the lower part of the snow rake rod strikes a stone or the like, the snow rake rod temporarily deflects further rearward. The snow lubrication device has relatively few components, is low in cost, and is hard to dislodge from a snowmobile.

A snow lubrication device for a snowmobile for running on snow, the snow mobile having an endless track belt driven with a drive wheel by the drive of an engine, wherein the track belt is pressed against the snow surface, wherein the snow lubrication device is configured to be attached to a front portion of the snowmobile for raking and scattering snow on the snow surface, the scattering snow lubricating a contact part between the track belt and a part of the snowmobile that is in contact with the track belt, wherein the snow lubrication device comprises:
- a fixing member comprising a fixing part fixed to the forward portion of the vehicle body of the snowmobile and a cylindrical member;
- a rod-shaped member having elasticity and having a first end part coupled with the cylindrical member of the fixing member;
- and
- a snow rake member provided separately from the rod-shaped member, the snow rake member having a root end part coupled with a second end part of the rod-shaped member and having a front-end formed with a blade part for raking snow toward the track belt, wherein the root end part of the snow rake member is thinner than the second end part of the rod-shaped member, the rod-shaped member being fixed to the snow rake member by placing the root end and the second end part of the rod-shaped member both within a cylindrical fixing member, and wherein a gap between the cylindrical fixing member and the root end part of the snow rake member is filled with adhesive.
