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 :

the momentum into heat, in other words, which transfers the kinetic energy into thermal energy. The brakes are used to reduce the speed of the vehicle, and the speed of conversion determines the rate of the vehicle slows down.

DISADVANTAGE :

The hydraulicsystem connects the brake pedal to the brake parts at each wheel.The basic hydraulic system principle is simple. We can regard it as aprocess that force applied at one point is transmitted to another point by using an impressible fluid, which almost always is an oil of somesort

PROPOSED SYSTEM :

This concept applies for devices like brakes and clutches, where a pad is pressed against a spinning disc. The more force that presses on the pad, the greater the stopping force.

ADVANTAGE :

one advantage of the hydraulic system is that the pipe can be any length and shape, therefore it could snake through all sorts of components separating the two pistons. The pipe can also fork, so that one master cylinder can drive many slave cylinders if need.
