Design Of An Auto-tilting Car 6a12s

A PROJECT REPORT ON

DESIGN OF AN AUTO-TILTING CAR Submitted in partial fulfillment of the requirements for the award of the degree of BACHELOR OF TECHNOLOGY In

MECHANICAL AUTOMOBILE ENGINEERING

ABSTRACT

The use of an electrical narrow tilting car instead of a large gasoline car should dramatically decrease traffic congestion, pollution and parking problem. This is the reason why most car companies are producing narrow track electrical car prototypes. These narrow track cars have an increased rolling tendency. In our project work we have tried to develop a tilting mechanism for a narrow track car to give it the flexibility of a motor cycle. This feature enables the car to tilt in to the curve while negotiating it. Our analysis shows that to increase the maximum curve at speed by more than 50%. The detailed calculations are enclosed within. The method we have used is a simple mechanical tilting system controlled by a simple DC stepper motor which is controlled electronically. This tilting mechanism if successful should dramatically increase the maximum speed in curves. This should also provide the advantages of increased enger comfort and handling.

The idea is to develop a tilting car of narrow track that seats two people in tandem. This can be operated on reduced lanes thereby increasing the effective capacity of highways.
