Truck's torque rod bushing

Design and Function of Torque Rod Bushings

Torque rod bushings are typically made of rubber or polyurethane. These materials allow for flexibility and energy absorption, which are key to their function. Their design and function include:

Function:

• Absorb Shocks and Vibration: Torque rod bushings act as a shock absorber for the forces generated by acceleration, braking, and road irregularities. They reduce vibrations that would otherwise be transmitted through the suspension system.

• Control Axle Movement: They prevent excessive movement of the axle, ensuring the axle remains aligned with the chassis, which is critical for vehicle stability and handling.

• Allow Controlled Flexibility: The bushings allow for a limited amount of flex or rotation, accommodating forces without causing undue wear on other suspension components.
