FIELD OF INVENTION
This invention relates to novel clutch mounting arrangement for better
compatibility, improved system life and heat dissipation during clutch function.
BACKGROUND OF INVENTION
Conventionally clutch mounting system is known to have been provided
comprising of fly wheel and clutch assembly. Reference may be made to fig. 1
indicating the same.Surface of flywheel provides face for clutch mounting and
clutch assembly is mounted on flywheel with bolts. For proper friction between
clutch disc and flywhee1,it is required to maintain proper material hardness grade
of flywheel. Heat energy is released while actuation and de-actuation of clutch.
The released heat energy results in temperature rise near clutch disc,which leads
to glazing /burning of clutch disc. The conventional systemis not provided with
any arrangement for dissipation of heat from the clutch and therefore faces
problem of clutch juddering. Thus, overall system results in reduced clutch disc
life and low clutch performance in heavy duty application.
OBJECTS OF THE INVENTION
An object of the present invention is to provide novel clutch mounting
arrangement which overcomes disadvantages associated with the prior art.
Another object of the present invention is to provide novel clutch mounting
arrangement which is efficient and reliable.
Yet another object of the present invention is to provide novel clutch mounting
arrangement which improves performance of clutch.

Still another object of the present invention is to provide novel clutch mounting
arrangement which increases clutch disc life and reduces cost of clutch.
At the outset of the description, which follows, it is to be understood that the
ensuing description only illustrates a particular form of this invention.
However, such a particular form is only an exemplary embodiment, and
without intending to imply any limitation on the scope of this invention.
Accordingly, the description is to be understood as an exemplary embodiment
and teaching of the invention and not intended to be taken restrictively.
BRIEF DESCRIPTION OF THE INVENTION
According to this invention, there is provided novel clutch mounting arrangement
comprising a special plate integrated with curved blades provided between
flywheel and clutch assembly.
One side of plate is used as a surface for clutch mounting and other side is
integrated with curved blades. The hardness of plate is controlled through
material selection and heating process to make it compatible with Clutch disc
hardness. Proper material which can satisfy the hardness grade is required for
proper friction during clutch operation. This ensures to allow for even low
hardness grade material for flywheel resulting in reduced material cost.
Integrated curved blades on plate provide dissipation of heat from the clutch disc
area. Dissipation of heat from clutch area helps to maintain the desired
temperature level near clutch disc. Due to desired working temperature the wear
rate of clutch disc is in control,which helps in enhancement of clutch performance
in heavy duty application.

The proflle of blade on plate is optimized for better air flow from clutch area
considering the direction of rotation, speed range and working space.
WORKING PRINCIPLE
Working principle is based on radial air flow fans. Integrated curved blades on
plate act as blades of radial air flow fan. As plate is mounted between flywheel and
clutch, it rotates as flywheel rotates. During rotation of hardened plate, the blades
on plate suck heated air from clutch disc and dissipate it outside the clutch area.
This helps to maintain the desired temperature level at clutch disc.
Advantageous Features
1. Improved clutch performance
2. Increase in cluiCh disc life
3. Reduction in the cost of clutch
4. Serviceability
