Smooth Chassis in Cantilever Suspension System


Published on Feb 12, 2017

Abstract

The objective of suspension system is to provide good ride and handling performance i.e.,vertical compliance providing chassis isolation, ensuring that the wheels follow the road profile very little tire load fluctuation, to ensure that steering control is maintained during maneuvering, wheels to be maintained in the proper position with road surface.

To ensure that the vehicle responds favorably to control forces produced by the tires during – longitudinal braking – accelerating forces, lateral cornering forces and braking and accelerating torques this requires the suspension geometry to be designed to resist squat, dive and roll of the vehicle body, to provide isolation from high frequency vibration from tire excitation, requires appropriate isolation in the suspension joints, Prevent transmission of ‘road noise’ to the vehicle body.

In existing suspension system there may be some lack of above objectives so there to modify the design of chassis to increase performance, flexibility and smoothness. So we propose the new type of design called smith chassis of cantilever suspension.

It consists of cantilever link joint to suspension spring which is made up of rubber. Cantilever joint is attached to the suspension and chassis

EXISTING SYSTEM:

WORKING PRINCIPLE:

It works on the cantilever suspension. To Reduce unsprung mass, Easier to adjust/tune (ride height, shock rates, spring rates and motion ratio can all be changed without tearing the entire rear end of the car apart) we use cantilever suspension. In this model we just fill the air in the suspension bag. When it is filled by compressor or any filler it raises the vehicle chassis above by cantilever link, so it improves the performance of the vehicle. Due to the air suspension flexibility also increased

ADVANTAGES:

The primary benefit is ride quality: Vehicles with air suspension are often said to "glide" over bumps, while traditional steel spring suspension can cause a harsher ride.

lso, air suspension is often adjustable. That means drivers can select a cushy ride if they're on a rough road or a harsh ride if they want to improve handling.

Another big benefit is that SUVs or trucks with the feature boast improved towing capabilities. In most of these SUVs or trucks, drivers can increase firmness when towing to account for heavier loads. That's not true of SUVs or trucks with spring suspension, where large loads can weigh down the vehicle.

APPLICATIONS:

• Used in four wheelers and two wheelers.
