Difference between rear suspension and front suspension
As the first point of contact with the road, the tires work in conjunction with the suspension geometry and weight transfer dynamics to provide grip. Many different types of tires exist, but every tire relies upon its contact patch with the road (Shown in diagram T1 below) to create the friction needed. Generally, the larger the contact patch, the larger the amount of friction created.
Complete Guide to Car Suspension
It is quite easy to get an idea of what a car’s suspension system does. From the term ‘suspension’ itself, it is already understood that you are essentially raising something from the ground – to suspend – in an effort to minimize the impact or effects of forces of the ground on this particular something.
Suspension design: definitions and effects on vehicle behavior
Toe is defined as the angular deflection from the vehicles centerline and the centerline of the rim. Positive toe (toe out) is defined as a wheel splaying out from the direction of travel. Toe Angle carries the same sign as Toe Distance.

When carried to the extreme, today’s emphasis on automobile mass reduction has significant implications for vehicle ride and suspension design. We therefore review traditional automobile suspension systems and offer comments on the special considerations of suspension systems of extremely low-mass passenger cars.
How Car Suspensions Work
The study of the forces at work on a moving car is called vehicle dynamics, and you need to understand some of these concepts in order to appreciate why a suspension is necessary in the first place. Most automobile engineers consider the dynamics of a moving car from two perspectives:
Inventor’s corner: A new twist on a fully independent vehicle suspension
The active control of suspension geometry has historically been a challenging perspective for chassis teams of worldwide automakers. Manufacturers and suppliers have offered different solutions, but few have succeeded in combining a marked improvement in handling performance, low-energy consumption, simplicity, and low cost.
Optimizing Vehicle Suspension Design through System Level Simulation
Optimization of vehicle ride and handling performance must meet many competing requirements. For example, vibration in the frequency range that causes driver discomfort needs to be minimized, which requires decreasing suspension stiffness. Yet the suspension deflection should stay within travel constraints, so suspension stiffness needs to be increased. The traditional practice of relying on test cars for suspension development is time consuming and costly.

The optimisation requirements of suspension systems and the state-of-the-art of suspension research in the last decade are reviewed first. It should be noted, however, that the available literature is vast and only a small portion of it can be presented here. This paper includes the well-known ride, handling trade-off optimisation, and geometrical optimisation of light commercial vehicle suspension systems. Some heavy vehicle suspension optimisation papers are also reviewed due to their conceptual contribution to the subject.
