The characteristics of pneumatic-tyred clutch are as follows: large transmitted torque, steady joint, easy to install, vibration absorption, compensation to an extent for the relative radial offset and relative angular offset of drive and driven shafts, small inertia of the driven parts, long service life, compact structure and good sealing.

Furthermore, due to great resistance to deformation of pneumatic tyres, the service life of such tyres will be shortened when the operating temperature is over 60°C, and they tend to become fragile when the temperature is lower than -20°C.

The joint element of a pneumatic clutch is mainly made up of friction disk and friction block and so on.

Pneumatic-tyred clutch can be divided into common type and ventilation type in terms of structure.
