<p>A ski suspension for snowmobiles with at least one rotatable steering spindle (2) comprises a spring means (16), as well as a shock absorber (6) for providing resilience and cushioning of relative movements between the chassis and a ski (3) connected with the suspension and steerable by means of the steering spindle (2). Furthermore, the suspension comprises, in addition to the first shock absorber (6) positioned in front of the steering spindle, a second shock absorber (7) provided with a progressive helical compression spring (16) and consisting of a piston-cylinder mechanism whose rear end is hingedly connected with the ski (3) at a first, fixed hinge point (11) and whose opposite end is hingedly connected with a pivotable link (12) at a second, movable hinge point (13), the link being hingedly connected with the ski at a third, fixed hinge point (14) as well as with the steering spindel (2) at a fourth, movable hinge point (15).</p> |
