Abstract
A traction device to engage a track of a tracked vehicle includes spaced apart longitudinal ribs and spaced apart transverse ribs forming a matrix, with at least one longitudinal rib having first gripping elements spaced apart to engage a track of a vehicle having lugs spaced at a first pitch and at least one other longitudinal rib having second gripping elements spaced apart to engage a track of a vehicle having lugs spaced at a second pitch. A number of third gripping elements are arranged across a width of each of the transverse ribs, and the transverse ribs are spaced to engage a track of a vehicle having lugs spaced at a third pitch.
Claims26
A traction device configured to engage a track of a snowmobile as the snowmobile moves in a direction of travel, comprising:
- a plurality of spaced apart longitudinal ribs substantially aligned with the direction of travel and a plurality of spaced apart transverse ribs that interconnect the plurality of spaced apart longitudinal ribs, a first longitudinal rib of the plurality of spaced apart longitudinal ribs having a plurality of first raised gripping elements spaced apart to engage a track having lugs spaced at a first pitch and a second longitudinal rib of the plurality of spaced apart longitudinal ribs having a plurality of second raised gripping elements spaced apart to engage a track having lugs spaced at a second pitch and a plurality of third raised gripping elements across a width of each of the plurality of transverse ribs, wherein the transverse ribs are spaced to engage a track having lugs spaced at a third pitch wherein the first pitch is 2.86 inches, wherein the second pitch is 3.0 inches, and wherein the third pitch is 2.52 inches.
A traction device for a snowmobile as the snowmobile moves in a direction of travel, the traction device comprising:
- a matrix having a plurality of spaced apart longitudinal ribs interconnected with a plurality of spaced apart transverse ribs, the longitudinal ribs being substantially aligned with the direction of travel;
- a first plurality of raised gripping elements spaced apart along a first longitudinal rib of the plurality of longitudinal ribs, the first plurality of gripping elements spaced to engage a track having lugs spaced at a first pitch;
- a second plurality of raised gripping elements spaced apart along a second longitudinal rib of the plurality of longitudinal ribs, the second plurality of gripping elements spaced to engage a track having lugs spaced at a second pitch;
- a third plurality of raised gripping elements spaced apart along a width of each of the transverse ribs, wherein adjacent transverse ribs are spaced apart from each other at a distance to engage a track having lugs spaced at a third pitch;
- and
- and further comprising a plurality of cutouts along a first face of each of the transverse ribs, and a plurality of cutouts along a second, opposite face of each of the transverse ribs.
A traction device configured to engage a snowmobile track with a 2.52 inch pitch, a 2.86 pitch or a 3.0 inch pitch when the snowmobile moves in a direction of travel, comprising:
- a plurality of spaced apart longitudinal ribs substantially aligned with the direction of travel, a first rib of the plurality of longitudinal ribs having raised gripping elements spaced apart to engage lugs on a snowmobile track with a pitch of 3.0inches and a second longitudinal rib of the plurality of ribs having raised gripping elements spaced apart to engage lugs on a snowmobile track with a pitch of 2.86inches;
- and
- a plurality of spaced apart transverse ribs that engage the plurality of spaced apart longitudinal ribs such that a matrix is formed, wherein the plurality of spaced apart transverse ribs have a plurality of raised gripping elements across a width, wherein the spaced apart gripping elements on the transverse ribs are spaced to engage lugs on a snowmobile track with a pitch of 2.52 inches.
