The BOSCH brand V-Ribbed Belts is a drive belt for ancillary units, which is used to transmit torque to auxiliary vehicle components, which include pump, air conditioner, generator, hydraulic booster.

The advantage of this simple device is the ability to transmit energy with a single element. The principle of operation of the V-ribbed belt is similar to that of the timing belt.

The torque from the crankshaft transmits torque simultaneously to the pulleys of several devices, each of which works due to the transformation of the obtained torque into another type of movement or transformation into electrical energy necessary for performing functions.

Principles of the V-ribbed belt

The versatility of the V-ribbed belt is due to its design and flexibility.

To ensure the operation of various systems, a belt is optimal, capable of providing a rigid transmission. In this way, torque is diverted to the generator, water pump and other systems. V-ribbed belts are a type of V-belts that allow you to reduce the bending radius of a flexible connection and increase the gear ratio.
