Automatic Tyre Inflation System in Dynamic Condition

In today's growing world, the possibilities of road accidents of any automobile are increasing at an alarming rate. The reasons for these happenings are the puncturing of tyres, when the vehicle is at very fast speeds due to any reason and because of that the driver loses his control over the vehicle. Many studies have revealed that a drop in the tyre pressure by a few PSI results in the following: · Reduction in the fuel economy · Reduction of tyre life · Reduces safety and performance of the vehicle We have hence developed an automatic, self-inflating tyre system which will ensure that the tyres are properly inflated all the time. In our design, we have made the use of an air compressor that will store compressed air in an air tank at the desired pressure value which in turn will supply air to all the four tyres through hoses and rotary joint fixed between wheel hub and knuckle of each wheel. The use of rotary joint is to efficiently allow the air to be channelled to all the tyres without the tangling of hoses. With the current environmental issues and fast depletion of natural resources our project will successfully improve the overall fuel economy of the vehicle along with the increased tyre life and improved vehicle handling.
