AUTOMATIC CLUTCH SYSTEM BASED ON PNEUMATIC

ABSTARCT :

The object sensor senses the object and gives corresponding signals. These electrical signals are very small mill voltage signal, so it is given to amplifier circuit. The amplifier circuit is constructed with operational amplifier which acts as power amplifier. Then the amplifier signal is given to signal conditioning unit which also constructed with operational amplifier. In this circuit operational amplifier act as comparator and generate the square pulse given to microcontroller. The microcontroller may be ATMEL/PIC/RENESAS/ARM microcontroller. It will work according to our object already we have programmed. Air compressor is used for ON/OFF the pneumatic, when the compressed air is passed to the pressure control valve; the required pressure is obtained by adjusting its knob. When the air is passed to the flow control valve, the speed of movement of piston (pneumatic) is controlled by adjusting the knob. According to the object sensor value, the microcontroller activates the driver circuit as per mentioned in the program. The driver circuit is constructed with transistor which acts as switch to control the relay. The relay output is directly connected to the Solenoid valve this is act as the ON/OFF tap and then solenoid valve output is connected to the Pneumatic cylinder which is attached in the Clutch assembly. Whenever relay gets on the Pneumatic cylinder air piston is force to the clutch assembly.

EXISTING SYSTEM :

DISADVANTAGE :

? Additional cost requires doing the automation Free from wear adjustment.

PROPOSED SYSTEM :

ADVANTAGE :

? Brake cost will be less. ? Free from wear adjustment. ? Less power consumption ? Less skill technicians is sufficient to operate. ? It gives simplified operation. ? Installation is simplified very much. ? To avoid other burnable interactions viz.… (Diaphragm) is not used. ? Less time and more profit.
