Leaf Springs (Suspension Springs)
These springs comprise multiple leaf springs stacked on top of each other for use in the suspension systems of commercial vehicles. They support stable traveling even when a vehicle is carrying heavy loads.
Tapered Leaf Springs (Suspension Springs)
The thickness of these leaf springs changes from the center of the spring to both ends, enabling generated stress to be made uniform.
Mono Leaf Springs
With optimal materials and shape, these single, lightweight and compact leaf springs offer high reliability.
Torsion Bars
These springs utilize the natural tension of twisted metal rods to return to their original shape. They are used for truck tilt cab suspensions and front suspensions for some trucks.
Stabilinkers
This part, used in air suspension trucks, serves two functions: as a link for receiving front and rear forces, and as a stabilizer for suppressing roll. It contributes to improving the road handling ability of trucks and reducing the weight of air suspensions.
