ABSTRACT:
A drive belt assembly for snowmobiles. The assembly includes an endless drive belt, which extends substantially across the entire width of the rear portion of the snowmobile, and is longitudinally and drivably supported on the snowmobile body. First and second sets of transversely and alternately positioned and spaced drive cleats are securely mounted on the outer surface of the drive belt. Each of the cleats has a first end portion which is adjacent one of the lateral edges of the belt, and a second end portion, which is spaced inwardly from the other edge of the drive belt. Surface portions are defined on the outer surface of the track longitudinally between each of the first end portions of one set of the drive cleats, and transversely between the second end portion of each of the other set of cleats, and the other edge of the drive belt. Flexible, unitary, lugs or projections extend from the outer surface portion. The drive cleats, which are of a futigue resistant design, and the flexible projections cooperate to provide forward traction for the snowmobile, while avoiding side slippage of the snowmobile as it is driven across the snow and/or ice.
