Design and Function Rear Suspension The VOLVO T-Ride Tandem Suspension is designed for use in both on-and off-highway applications. It offers maximum atriculation for traction. The parabolic tapered spring leaves are mounted upside-down outside the frame rails. The ride is further enhanced by rubber cushions bolted to the end of each spring resting on the respective rear axle.
Group 72 Design and Function Bogie Bracket (Saddle Bracket) The Bogie Bracket assembly (saddle bracket) provides stability for lateral movement and serves as an anchor for the spring cradle and the parabolic spring assembly. It helps maintain maximum articulation of the suspension as well as durability.
Group 72 Design and Function Parabolic Spring Leaves The parabolic spring leaves are mounted upside down and outside of the frame rails. They are fastened to the spring cradle and provide the lightweight suspension with excellent ride characteristics. This design contributes to axle flexibility while maintaining contact to the ground for W6001341 pulling power.
Group 72 Design and Function V-Stay Torque Rod Frame Bracket The V-Stay torque rod frame bracket is used to mount the V-Stay torque rod to the frame. It is marked with top and forward arrows to make for proper installation. This bracket supplies a secure anchor for the V-Stay torque rod to the frame.
