An improved suspension system for the drive track of a snowmobile that offers wide amounts of suspension travel and yet is compact enough to be positioned internally of the track. The suspension system permits the use of a tubular shock absorber and a surrounding coil spring for both the front and rear portions of the track. Both front and rear suspension systems embody a link arrangement for moving the ends of the shock absorber and spring toward each other upon upward travel of the track relative to the snowmobile body so as to achieve a wider range of damping for a given degree of suspension travel.

A suspension system for a vehicle such as a snowmobile or the like comprising a body and a ground engaging track or the like, said suspension system comprising a suspension element having a pair of relatively movable portions adapted to resiliently resist such relative movement, and means for operatively interposing such suspension element between said track or the like and said body for moving each of said portions of said suspension element in opposite senses relative to the other upon movement of said track of the element relative to the body comprising a bellcrank having an intermediate portion pivotally supported by the body and having opposite arms, a link pivotally connected to one of said bellcrank arms, a lever pivotally supported relative to said body, said link having a pivotal connection to said lever, one portion of said suspension element being pivotally connected to said lever and means for operatively connecting the other of said bellcrank arms to the other of said suspension element portions.
