Constant heavy or changing loads, as well as trailer dynamics, place high demands on both vehicle and driver. Extra weight on the rear axle shifts the center of gravity, and exerts a major impact on driving performance in the process. In critical situations, the vehicle can be very difficult to control, while inconsistent responsiveness makes driving comfort nearly impossible. Other consequences can be expensive. Fuel consumption rises, and tire wear increases due to uneven power transmission. Greater strain is also placed on the axle as a whole. The Nivomat®, the leveling system from ZF, counters the negative effects of loads. There are many vehicle applications, especially in mid-sized classes, such as station wagons, vans, SUVs and sedans that offer the Nivomat® as an option. The Nivomat is available as a damper, spring damper, suspension strut, or suspension strut module.
