The picture is just a part from a clutch and most probably is from small Farm tractor (Wheel Tractor) or motorcycle clutch.
For automotive specially heavy duty truck clutches you can check on: http://ruen.mk/ also contact me.
i searched a lot and found that the single plate clutch design shown here is mostly used in tractors and the multi plate clutch design is also used for different engines. I wanted to know which particular industry or company manufacture such type of designs. both these clutches don't use diaphragm springs. many users here have designed these two clutches and uploaded it but no one has mentioned the name of the clutch or their particular manufacturer. .
thank you for the reply.
