Elastic multi V-belt for modern engines

1st Quarter 2019 Shaft power components

ContiTech has introduced a new elastic multi-V Belt to the southern African automotive market that enables non-positive power transmission of torque in belt drives without a tensioning pulley. Instead, the belt is engineered with integrated tension members, which enables it to maintain tension throughout its lifetime. Designed to meet the demanding requirements of modern engines, the new V-belts can be used to drive a wide range of automotive systems, including alternators, fans, water pumps, air-conditioning compressors and power steering.

The multi V-Belt is made up of three main components: a cover coat, the tension member and rib coating. The cover coat features a textured reverse consisting of synthetic rubber with a high wear resistance. Specialised coating is also employed on the ribs, which guarantees good noise properties and an ideal grip, even on a slightly misaligned drive.

These belts are directly subject to constant movement and environmental stresses such as dust, dirt and high and extreme temperature ranges, and ContiTech recommends changing these belts after 120 000 km. During service and repair work on a vehicle with a factory-fitted elastic belt, this component must be replaced with another elastic belt. Normal multi V-belts do not work in these vehicles because of their different construction. Also, it is important to use the correct tools when working with any V-belt, and ContiTech offers a complete range of special tools and belt sets.
