3-Point bogie beam rear suspension The Volvo hauler’s superior off-road performance is the result of the unique 3-point bogie beam design (1) , allowing the rear wheels to move independently in order to maintain good ground contact and vehicle stability. Maintenance-free The Volvo bogie beam design is constructed using sim- ple and functional mechanical parts. A straddle mounted bogie beam (2) on each side connects the two rigid oscillating axles (3) . Flexible rubber pads (4) (bogie blocks) connect the axles and bogie beams. Cross stays (5) , linking the bogie axle and the frame, absorb lateral forces. A-frames (6) with rubber bushings (7) further control axle movement by absorbing the acceleration and braking forces. Rubber connections and a durable rug- ged design equal a long life, maintenance-free suspen- sion with high productivity. Short cycle times The bogie design with its long suspension travel and high ground clearance gives the load unit a smooth, “floating” ride while maintaining ground contact for excellent trac- tion at all times. A smooth ride translates to operator comfort, which reduces cycle times and increases pro- ductivity. Stability The long suspension travel and independent wheel movement provided by the bogie beam system allows the body to stay level while the hauler travels over large bumps and ruts. This long suspension travel not only maximizes load unit stability but also keeps the load in the body when traveling over rough surfaces.
