V-ribbed Belt
The V-ribbed belt is a further development of the V-belt and works according to the same principle: It acts as a transmission belt, connects the V-belt pulleys and transmits the force from the engine to the ancillary components including the alternator, the hydraulic pump for the power steering, the air conditioning compressor, the fan and the water pump.
In a combustion engine, the combustion of the air/fuel mixture drives pistons. Via connecting rods, the movement of these pistons in a straight line is converted into the rotation of the crankshaft. The V-belt uses the force from the rotation (torque) of the crankshaft and drives additional units via V-ribbed belt pulleys. As such it is responsible for the correct operation of the engine and high levels of ride comfort. The V-ribbed belt has an advantage over the V-belt in that it is able to transmit the torque from the engine to several units at the same time.
