Fig. 4.2. Front suspension components

Thanks to the optimal arrangement of components, the front suspension provides a smooth and comfortable ride, excellent handling and cross-country ability.

Maintenance recommendation

Before disposing of the shock absorber, the low pressure gas should be released from it for safety reasons.

Shock absorber

To ensure directional stability and a smooth ride, the vehicle is equipped with gas-filled (N₂) low-pressure shock absorbers with a valve with a linear characteristic.

Linear characteristic valve device

Fig. 4.4. Design of a valve with a linear characteristic

A linear valve consists of the following parts: C-valve, shut-off valve and check valve. These valves form a multi-layer structure with passage holes. At low piston speed, the liquid passes through the gaps in the valves, creating a damping force.

The use of a valve with a linear characteristic ensures a constant damping force at low piston speeds and, as a result, a smooth ride of the vehicle.

Front wheel axle

Fig. 4.5. Front wheel axle design

The front wheel axle is mounted on a double-row radial thrust ball bearing with low rolling resistance.

The axle is securely fastened with a 12-point lock nut. This lock nut is not reusable.
