Abstract
A snowmobile track suspension is disclosed. The track suspension includes a chassis, a skid frame, a front arm, an idler arm, and a rear arm. The chassis includes a tunnel. The skid frame includes rails along which the track rides. The front arm has a forward end pivotally and slidably connected to the tunnel. The front arm also includes a rearward end pivotally connected to the rails. The idler arm includes a forward end pivotally connected to the tunnel and a rearward end connected to the rear arm. Such connection is at the upper end of the rear arm, with the lower end of the rear arm pivotally coupled to the rails.
Claims35
A track suspension for a snowmobile having a chassis and a skid frame with at least one rail, the track suspension comprising:
- a. a front arm having a first end pivotally coupled to the chassis and a second end pivotally coupled to the rail, at least one of said first and second ends being coupled with a front-arm link;
- and
- b. a rear arm having a first end pivotally coupled to said chassis and a second end pivotally coupled to said rail, at least one of said first and second ends being coupled with a rear-arm link.
A snowmobile track suspension comprising:
- a. a chassis having a tunnel;
- b. a skid frame having at least one rail;
- c. a front arm having an upper end pivotally coupled to said tunnel and a lower end pivotally coupled to said rail, at least one of said upper and lower ends being coupled with a link;
- and
- d. a rear arm having an upper end pivotally coupled to said tunnel and a lower end pivotally coupled to said rail, at least one of said upper and lower ends being coupled with a link.
A snowmobile track suspension comprising:
- a. a chassis having a tunnel;
- b. a skid frame having rails;
- c. a front arm having a forward end pivotally and slidably connected to said tunnel and a rearward end pivotally connected to said rails;
- d. an idler arm having a forward end pivotally connected to said tunnel and a rearward end;
- and
- e. a rear arm having an upper end pivotally connected to said idler arm and a lower end pivotally coupled to said rails.
A track suspension for a snowmobile having a chassis and a skid frame with at least one rail having a longitudinal axis, the snowmobile having a forward end and a rearward end, the track suspension comprising a front linkage arm having a first end coupled to the chassis and a second end coupled to the rail, said ends being pivotally coupled to the chassis and rail about axes substantially transverse to the longitudinal axis of the rail, wherein at least one of said first and second ends is slidably coupled so as to move forward and rearward relative to at least one of the chassis and the skid frame.
