Abstract
An improved rear suspension for a snowmobile. The improved rear suspension includes a first link and a second link, each having a first end and a second end. An extensible, shock mounted link also has a first end and a second end. The first and second links are non-pivotal relative to each other. A first pivot is defined on the snowmobile frame, a second pivot is defined on the snowmobile frame rearwardly of the first pivot, and a third pivot is spaced downwardly of the first and second pivots. A fourth pivot is movably located relative to the first, second and third pivots. The first ends of the first and second links are pivotally carried by the first pivot, the second end of the first link is pivotally carried by the third pivot, the second end of the extensible link is pivotally carried by the second pivot, and the second end of the second link and the first end of the extensible link are pivotally connected together at the fourth pivot. The first and second links, the extensible link and the locations of the first, second, third and fourth pivots cooperate to define a suspension assembly for the rear of the drive belt support relative to the rear of the snowmobile frame while permitting significant relative movement between the drive belt support and the snowmobile frame.
