INDEPENDENT WHEEL VEHICLE SUSPENSION

INDEPENDENT WHEEL VEHICLE SUSPENSION

ABSTRACT

    The suspension system connecting a vehicle body to the wheels and its type allows the wheel to move in an essentially vertical direction in response to good surface irregularities, a spring element temporarily stores and releases energy thus insulating the vehicle body from acceleration peaks. A shock absorber or ‘ damper ’ insures that oscillation induced by road unevenness or aerodynamic forces ( or by accelerating braking ) which would impair ride comfort and road holding die away quickly.

    Conventional system provides greater simplicity. They contain systems like rigid asle suspension. They are widely used in heavy carriers. Suspension is directly using leaf spring hence they have less complexity. In this system both the wheels of the vehicle are suspended in combination as directly axle is suspended. Simplicity is the only advantage they do not provide effective suspension.

    With development of technology a new concept called independent wheel suspension has emerged. In this system both the wheels are suspended independently as every wheel has its independent suspension system. This provide suspension for actual road conditions. This system is very complex but have advantages like low weight, plenty of scope for achieving favourable elasto – kinematics effects, no coupling of masses, no suspension parts that run right across the vehicle. Hence nowadays in most of the passenger cars this system is used and preffered over conventional system, providing thereal sooth drive.
