DESIGN DEVELOPMENT ANALYSIS & TESTING OF AUTOMATIC TYRE SELF INFLATION WITH HYBRID -MECHANICAL VALVE SYSTEM

Mechanical Engineering

Studies performed earlier indicate that reduction in tyre pressure by just a small value (below28 PSI )can result in the reduction of fuel mileage, reduction in tire life, compromised safety, and deteriorated vehicle performance. In attempt to design and develop an automatic, self-inflating tire system that ensures that tyres are properly inflated at all times. Earlier design proposes and successfully implements the use of a portable compressor that will supply air to all four tyres via hoses and a rotary joint fixed between the wheel spindle and wheel hub at each wheel. The rotary joints effectively allow air to be channelled to the tyres without the tangling of hoses. With the recent oil price hikes and growing concern of environmental issues, this system addresses a potential improvement in gas mileage; tyre wear reduction; and an increase in handling and tyre performance in diverse conditions. This system is commercially available in the market by the name AERIS ---made by STEMCO .These systems have a prerequisite of an inbuilt compressor , tyre pressure monitoring system and sea of complex components to fulfil the operation of automatic tyre inflation
