A LIFTABLE VEHICLE BODY BOTTOM SKIRT ALONG WITH FRONT AND REAR COLLAPSIBLE WIND FRICTION REDUCTION ATTACHMENTS FOR BETTER FUEL ECONOMY

摘要

In the automobiles one of the prominent wind friction area is the under body friction of vehicles. To reduce the under body wind friction of Buses, Trucks no. of bottom skirts are designed, but still the minimum ground clearance around 20 centimetre is maintained for avoiding the under body clash with speed breakers and other pits and bumps on the road. In the present invention a collapsible liftable under body skirt is designed for both body sides and front and rear wind friction reduction attachments, which will lifted automatically to the required height when the vehicle speed is reduced to around 45 KMPH so that the underbody friction is reduced at high speeds for better fuel economy.
