Valtra is to introduce the AIRES air-suspended front axle option on the Valtra N Series range in 2019.
Air suspension is widely used on commercial vehicles, but on tractors it has been a unique Valtra feature for the last 25 years. An air-suspended front axle offers a faster response and better shock absorption level particularly in fast axle movements and when the axle load is changing rapidly like in front loader use. This makes operator comfort and traction superior over hydro-pneumatic solutions.
The AIRES suspension on the N Series is similar to the well-proven and widely appreciated construction on the Valtra T Series. It features a separate, self-levelling pneumatic suspension with one air bellow as well as two robust shock absorbers. The suspension system uses compressed air which is sure to work also in cold temperatures. As an added benefit the tractor’s pneumatic system also allows for the usage of compressed air for other purposes such as trailer braking, cleaning dust off radiators or other daily maintenance tasks.
The advantages of a pneumatic front axle suspension are becoming clearer as the total weight of tractors is increasing with large front implements and front loaders. Increased tractor speeds and the use of pneumatic brakes to meet increased safety standards of the EU Mother Regulation also support this solution. The new front-axle suspension will become available on stage V compliant versions of the N Series in spring (N174 models) and in autumn 2019 (N134 and N154 models). The current, second generation hydro-pneumatic suspension option will continue to be available on smaller models of the N Series.
