Kelkkajouset

Kelkkajouset is a Finnish term that translates to "sled springs" or "snowmobile springs." It generally refers to the suspension systems used on snowmobiles, which are designed to absorb shocks and vibrations from uneven terrain. These systems are crucial for rider comfort, stability, and the overall performance of the snowmobile.

The primary components of a kelkkajouset system typically include springs and shock absorbers. The springs, often coil springs or torsion springs, provide the elastic force to support the weight of the snowmobile and rider, and to return the suspension to its original position after compression. Shock absorbers, usually hydraulic or gas-filled, dampen the oscillations of the springs, preventing excessive bouncing and ensuring a smoother ride.

Modern snowmobiles employ sophisticated kelkkajouset designs to handle a wide range of conditions, from groomed trails to deep powder. Independent front suspension systems are common, allowing each front ski to move independently for better control and comfort. Rear suspension systems, often a type of unimount or coupled design, are engineered to manage the forces generated by the track and provide traction. The tuning of the kelkkajouset, including spring preload and shock absorber damping, is vital for optimizing the snowmobile's handling characteristics for different riding styles and terrain types.
