The function of torque rod is simple, it helps in preventing the axle’s housing from twisting when you apply brakes or give acceleration. And for this, torque rod majorly depends on the torque rod bushes installed in the vehicle which provides it with a cushioning effect. As a result of this, the bushings cushion the joints and prevent tremors/ shocks that are transferred from tires to the chassis while your vehicle is on the move.
Usually, the torque rod bushes are designed using rubber (both natural rubber of different grades and alternative elastomers) and exhibit excellent torsional stiffness and high rated axial and radial load withstanding capacity. These rubber bushes feature a rubber cylinder bonded on their outer and there are inner surfaces to rigid metal layers. While a large variety of torque rod bushes are available in the market in standard sizes and specifications, customized or special requirements or sizes for suiting specific application can also be made to order. Torque rod bushes especially find widespread usage in linkages of under carriage of railway coach, trucks, trailers and dumpers among others.
