2010 Peugeot RCZ - Cutaway Suspension -

History of Peugeot..

Peugeot was founded in 1810 by the French family of the same name, yet it wasn't until the 1890s that the famed lion trademark was granted and not until 1891 that the company started to produce their first car. In 1889 they created four vehicles and over the next decade they slowly expanded so that by 1910, 300 cars were being produced per year. However, the uncomfortable driving conditions of these early models led them to fall into disrepute, so Peugeot rectified the problem by covering their car wheels with rubber. As a result, Peugeot was the very first car manufacturer to use rubber on the tyres of their vehicles.

Over the next twenty years the company went from strength to strength and in 1929 the Peugeot 201 was launched, which was the least expensive production car available at the time. It was this car that helped to secure Peugeot through the Great Depression and enabled them to survive until their economic situation improved. After the war, production continued on the 202 and then in the 1950s the Peugeot 203 was produced. This model had hydraulic brakes and rack-and-pinion steering as well as suspension. With rapid sales and record breaking profit levels for this vehicle, the company had sustained growth right into the 1960s.

Two decades later Peugeot launched the Peugeot 205 in 1983, which helped the company to make a name for itself as a global car production company. Ten years later the 306 was placed on the market. This was an extremely popular family car that stayed in production until 2001, at which time the Peugeot 307 was launched. In recent years, a diesel-electric hybrid Peugeot 307 was manufactured which could hit speeds of 80 miles per hour, however this model was just a concept vehicle and failed to be launched commercially. Nowadays the company is still developing low-carbon vehicles using hybrid electric power train technology and Peugeot PROLOGUE HYmotion4. At present, these have only been installed in concept cars but they may well be incorporated into new models in the coming years.

suspension system for AUDI TT (front axle)

Wishbones, ball joint and bracket

The ball joint is connected to the wishbone at three bolting points. compared to the Audi A3, the fastening bolt are integral part of a separate retaining element. the bolts and retaining element are inserted from above through the wishbone and ball joint. the wishbone is attached directly to the subframe at the inside front and to the body at the inside rear by means of an aluminium bracket.

The ball joint is in a lower position then on the Audi A3. The result is a higher centre of roll. this improves roll stabilization and gives particularly sport handling. the centre of roll is the level with the front axle in the centre of the vehicle about which the body pivots when subjected to lateral forces,e.g. when cornering.

Anti-roll bar


A tubular anti-roll bar is used on models with front wheel drive, while a solid bar is used on quarrto models. The link rod is a carry over part from the Audi A3.

AXLES


Front Axle 
Overview

An improved version of  the McPherson suspension is employed. The design of the front axle is identical to that of the Audi A3. Track width is 13mm wider on each side than the Audi A3. Detail modifications have been made to reflect the particularly sporty character of the Audi TT. In addition to the tuning parts (springs, dampers and antirool bars), the same axle components are used in all TT suspension variants.

System Components
Subframe

The aluminium subframe bears the wishbones, the anti roll bar and steering gear of electromechanical steering system. the two brackets for mounting the wishbones are now common part. the Audi TT is living proof thant sportiness and lightweight design go hand in hand. the illustration shows the aluminium components of front axle.

Swivel Bearing, Wheel Bearing
The aluminium swivel bearing manufacturing using Cobapress technology is a new part its geometric design allows a wider track width to be achieved. stell bruhes are press fitted into the swivel bearing at the track rod and ball joint mounting points. the third generation wheel bearing is bolted to the swivel bearing. the wheel bearing are carry-over part from the Audi A3. The screws are now coated with a chomium 6 free material to protect the environment. the suspension strut is connected to the swivel bearing by a clamp coupling.
