To start the engine or shift the gears,the drive has to depress the clutch pedal with
the purpose of disengagement the transmission from the engine.At that time,the
driven members connected to the transmission input shaft are either stationary or rotating ai a speed that is slower or faster than the driving members connected to the engine crankshaft.There is no spring pressure on the clutch assembly parts.So there is no friction between the driving members and driben members.As the driver lets loose the clutch pedal,spring pressure increases on the clutch parts.Friction between the parts also increases.The pressure exerted by the springs on the driven members is controlled by the driver through the clutch pedal and linkage.The positive engagement of the driving and driven members is made possible by the friction between the surfaces of the members.When full spring pressure is applied,the speed of the driving and driven members should be the same.At the moment,the clutch must act as a solid coupling device and transmit all engine power to the transmission,without sliping.
