According to Hendrickson Truck Suspension Systems, its weight saving HTB LT rear air suspension is now available on International ProStar trucks.
A lightweight, non-torque reactive rear air suspension, HTB LT delivers the additional advantages of smooth ride and low maintenance and weighs in as the lightest suspension in its class, saving up to 263 lbs. compared to industry standard 40,000 lb. suspensions.
Fleets in weight-sensitive applications such as tankers, bulk haulers and refrigerated carriers, where a pound saved is an additional pound of payload hauled, may benefit from the suspension. Its optimized design features parallelogram geometry, which eliminates leaf springs and reduces components for weight savings. An innovative torque box system improves multi-axial stability and control, the company said.
The cross-member, frame hangers and torque rods are designed to reduce weight while improving durability. Large, direct acting air springs carry 100% of the vertical load, compared to trailing arm suspensions where vertical load is shared between air springs and leaf springs. This key difference reduces vibration and harshness, the maker explained. The suspension’s centrally placed frame hanger eliminates the dual hangers found in a trailing arm suspension. Innovations like shock absorber mountings integrated with the torque rod further reduce complexity and part count, Hendrickson noted.
