Clutch mechanism making with video

A Clutch is a mechanism for transmitting rotation, which can be engaged and disengaged. Clutches are useful in devices that have two rotating shafts. In these devices, one shaft is typically driven by a motor or pulley, and the other shaft drives another device. In a drill for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so that they can either be locked together and spin at the same speed (engaged), or be decoupled and spin at different speeds (disengaged).


There are many different vehicle cultch designs but most are based on one or more friction
discs, pressed tightly together or against a fly wheel using springs.

Clutches found in heavy duty applications such as trucks and competition cars use ceramic clutches that have a greatly increased friction coefficient, however these have a “grabby” action and are unsuitable for road cars.


The raw material required for the manufacture of clutch and parts are steels, graphite, phenolic   resin and asbestos fiber.

The manufacturing process of clutches and its parts comprises mixing graphite and phenolic resin to form a graphite mixture. Then soaking an asbestos fiber string with in graphite mixture will follow. Removing the soaked string such that phenolic resin content of between 14-24 weight percents and graphite content of between 1-8 weight percent for every 100 weight percent is produced. Then bonding the string to the clutch facing so that the Rockwell hardness of the clutch facing is 20 - 60 on the Moh scale.

The linings and the steel are then cut to the required size and punched. Then using the trimming machine, trimmed the edges to ensure exact alignment with the shoe and the brake drum.

The clutches are then drilled and riveted, and bonded to the prepared brake shoes. The production process has no any adverse environmental impact.
