The tensioner pulley requires a certain amount of torque during actual use to maintain appropriate belt tension, avoid belt slippage, and compensate for elongation caused by belt wear and aging. When the belt tensioner pulley operates, the moving belt may induce vibrations in the tensioner pulley, leading to premature wear of the belt and pulley. Therefore, a resistance mechanism is added to the tensioner pulley. However, due to the many parameters that affect the torque and resistance of the tensioner pulley, and the varying effects of each parameter, the relationship between the components of the tensioner pulley and torque and resistance is very complex. Changes in torque directly affect changes in resistance and are the main influencing factor of resistance, with the main factor affecting torque being the parameters of the torsion spring. Properly reducing the inner diameter of the torsion spring can increase the resistance value of the tensioner pulley.

The role of the tensioner pulley is to adjust the tightness of the timing belt. It is generally replaced together with the timing belt to avoid future concerns. Other parts do not necessarily need to be replaced. Regular maintenance is sufficient.

Balanced suspension type

To address the potential issues mentioned above, multi-axle vehicles typically use a balanced suspension structure. A balancing mechanism is hinged on the frame between the two axles (such as the middle and rear axles in a three-axle vehicle). This way, when one wheel is lifted, the rotation of the balancing mechanism will lower the other wheel. If the two arms of the balancing mechanism are of equal length, it can ensure that the vertical loads on the two axles are equal under any circumstances, thus preventing the phenomenon of one wheel being suspended and unequal vertical loads on the two axles.
