The V-ribbed belt tensioner lever is often referred to as an auxiliary part of a car's belt drive, and its importance in the operation of this drive is underestimated.

The V-ribbed belt tensioner lever is a device that generates a certain predetermined force on the tensioning roller for correct and constant tension of the V-ribbed belt. In order to avoid vibrations of the belt and roller, a vibration damper or shock absorber is additionally installed. Typically, this is a hydraulic device that absorbs vibrations by dissipating their energy in the fluid flowing through the throttle.

The principles of the tensioner lever functionality

The INA brand Tensioner Lever, v-ribbed belt generates vibration even when it is well tensioned. This significantly shortens its resource, the resource of the guide rollers and irritates the driver. It is to remove vibration from the belt that the tensioner levers are invented. They absorb and dampen vibration in the throttle fluid.
