| 发明名称 | Snowmobile | ||
| 摘要 | A snowmobile includes a chassis comprising a bulkhead and a tunnel, a front suspension coupled to bulkhead, a rear suspension coupled to the tunnel, and slide rails coupled to the rear suspension. The rear suspension includes a toggle link pivotally coupled to the tunnel at a first pivot coupling, and a rear control arm coupled between the slide rails and the toggle link. The toggle link is pivotally coupled to the rear control arm at a second pivot coupling. The rear suspension also includes a carrier roller coupled to the toggle link. The toggle link is movable to a plurality of positions relative to the toggle link to vary the dynamics of the vehicle propulsion. | ||

| 主权项 | 1. A snowmobile, comprising: a chassis, comprising a bulkhead and a tunnel; an engine supported by the chassis; a front suspension coupled to the bulkhead; a rear suspension coupled to the tunnel; and slide rails coupled to the rear suspension; the rear suspension comprising: a toggle link pivotally coupled to the tunnel at a first pivot coupling, and a rear control arm coupled between the slide rails and the toggle link, the toggle link being pivotally coupled to the rear control arm at a second pivot coupling;a carrier roller directly coupled to the toggle link, the carrier roller being movable to a plurality of positions relative to the toggle link to vary propulsion dynamics of the vehicle; anda front control arm coupled between the slide rails and the tunnel. | ||
