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.
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.

The suspension model shown in Figure 2 has two inputs, and both input blocks are blue on the model diagram. The first input is the road height. A step input here corresponds to the vehicle driving over a road surface with a step change in height. The second input is a horizontal force acting through the center of the wheels that results from braking or acceleration maneuvers. This input appears only as a moment about the pitch axis because the longitudinal body motion is not modeled.
The motion ratio of a live axle setup is shown here. Over two-wheel bumps, the motion ratio is 1:1. Over single wheel bumps and during body roll, the motion ratio as shown in step 1. The motion ratio is only used for calculating roll resistance, not for suspension frequencies.
The AIRMATIC air suspension system.
Bumpy country road or modern motorway: the AIRMATIC air suspension system adapts the suspension to the prevailing conditions. The damping of each wheel self-adjusts according to the current driving situation and the condition of the road. This happens fast and precisely by means of two separate valves for rebound and compression in each damper. AIRMATIC thereby provides maximum ride comfort for any situation.
Steering and Suspension
The steering and suspension systems are key safety-related systems that largely determine your car’s ride and handling. Have these systems checked at least once a year. A good time to get them checked is with your wheel alignment.
Vibrating steering wheel? Hard to turn? Is it time to get your suspension system checked?
Z55 Autoride is a type of suspension option on many full-sized GM SUVs, indicated by the RPO code Z55. RPO codes are Regular Production Options, which identify the specific configuration each vehicle has when it leaves the factory. In most cases this is a sticker located on the inside door of the glove box, with multiple three character codes listed to show what that specific vehicle has as far as trim, suspension and engine configurations.

While there are many benefits of air suspension for luxury cars like a Land Rover, you won’t be able to enjoy these benefits if there is a leak. Here are five tips that will help you detect a leak in your land rover air suspension.
