Abstract
A snowmobile drive track includes an endless body having a ground engaging outer side on which is displayed, on every three successive crossbar receiving areas, a tread pattern which is repeated over the entire outer side. This profile configuration allows for a reduction of rubber material on the track and, therefore, a reduction of noise produced by the track as it rotates.
Claims18
A snowmobile drive track comprising an endless body having a ground engaging outer side and a suspension supporting inner side;
- said body defining a central portion and opposite lateral portions interconnected by a plurality of longitudinally spaced suspension bearing portions;
- said body displaying a plurality of longitudinally spaced crossbar receiving areas extending crosswise of said body in said central, lateral and suspension bearing portions;
- each said crossbar receiving area displaying, on said outer side of said body, integrally formed projecting profiles;
- the profiles of three successive crossbar receiving areas defining a tread pattern which is identically repeated on all successive threesome of crossbar receiving areas;
- the profiles of at least one of said three successive crossbar receiving areas differing in configuration from the profiles of the others:
- each said crossbar receiving area including a profile free region thereon but said track being free of profile free regions when viewed in a longitudinal direction to provide noise reduction when said track is driven.

Apparatus, comprising:
- a drive track including an endless body having an outer side and an inner side,
- said endless body defining a central portion, a first lateral portion connected to said central portion with a first bearing portion, and a second lateral portion connected to said central portion with a second bearing portion,
- said endless body including a plurality of crossbar receiving areas extending 1) in a cross-wise direction relative to said endless body and 2) across said first lateral portion, said first bearing portion, said central portion, said second bearing portion, and said second lateral portion,
- each of said crossbar receiving areas including, on said outer side, 1) a series of integrally formed profiles extending in said cross-wise direction and 2) a profile free region, the profiles of three successive crossbar receiving areas defining a tread pattern which is identically repeated on all successive threesome of crossbar receiving areas, the profiles of at least one of said three successive crossbar receiving areas differing in configuration from the profiles of the others, said drive track being free of profile free regions when viewed in a longitudinal direction to provide noise reduction when said drive track is driven.
