At the time major accidents this column impact to the driver and thus in system which reduces frontal injury to the driver in case of frontal accidents. Our project deals with the idea of this way driver get injured. A collapsable steering implementing collapsable steering column in the car which mechanism is a system which reduces to frontal helps to absorb the impact experienced to the driver at the impacts on driver by collapsing a part of the system. time of accident. By considering this collapsable steering The collapsable steering column can absorb most of the system we presenting a new idea of pneumatic operated frontal impacts being transferred towards the driver. collapsable system. The existing collapsable columns consist of the inner and outer sleeves which are engaged together by using Key Words: Pneumatic operated collapsable steering steel bearing in between two sleeves. These steels system (PCS). bearing are pressed into sleeves and all this assembly 1.INTRODUCTION can be covered with strong resin which is acting safeguard to steering column. At time of accidents as A steering column is mechanical system which is impact on steering rod increases then these both inner connecting the steering wheel to the mechanism of the and outer sleeves moves into each other in this way front wheels of an automobile. A commonly steering collapsable action can be takes place. column can transmit the work effort from the driver to the front wheels by the correcting decision of driver. 3.Working of Pneumatic Operated Collapsable The various function can be performed by the steering Steering System column mechanism are as follows: In this paper we give new idea about collapsing the (1) To guide the front wheels. steering column by using pneumatic piston-cylinder (2) Give right direction to the front wheel as given by arrangement. the driver. (3) It acts as a support to the steering wheel. Whenever a vehicle get accident limit switch gets active In this paper we can collapse the steering column by using pneumatic operated piston-cylinder and then signal passes through the 5/3 solenoid arrangement. This piston-cylinder arrangement can be operated direction control valve. It has four chamber operated by using 5/3 direction control valve from the upper two valves connected in inlet and outlet to the limit switch which is placed in front of the vehicle. If pneumatic cylinder and lower two valves one any body strikes to the vehicle at front side then it can connected in compressor and another one open to the automatically activate the limit switch and it gives atmosphere. quick signal to the 5/3 direction control valve and then it can operate the piston-cylinder arrangement thus the Whenever circuit get complete compressor get signal steering gets lowered within the fraction of seconds. to increase cylinder pressure steering mechanism 2.COLLAPSIBLE STEERING COLUMN moves away from driver, between double acting double rod cylinder and rack & pinion mechanism we have Generally a steering column is a long hollow or rigid compressible part which can easily compressed shaft that is connected from steering wheels to the whenever steering mechanism pressure increases steering rack and pinion gear box. In older vehicle this afterword’s when mechanism settle down remaining steering column is the only mechanism that used to pressure exit to the atmosphere. control vehicle. Thus the design of this steering rod is
