Il existe d’autres systèmes que ceux cités mais qui ne sont pas ou peu utilisés en automobile comme les suspensions à bras tirés, télescopiques ou coulissantes.Du nom de son concepteur, le MacPherson est le système le plus utilisé sur l’essieu avant à roues indépendantes des véhicules de tourisme car il est peu coûteux tout en étant efficace en terme de tenue de route grâce à la prise de carrossage négatif à l’abaissement (inclinaison de la roue vers l’extérieur).On retrouve, de nos jours, ce système à double triangulation sur les voitures sportives et/ou haut de gamme et, surtout, en compétition automobile mais il a été beaucoup utilisé avant la quasi généralisation du MacPherson sur les voitures de série (Exemple : Renault R4, R5).La suspension hydraulique est en fait de type oléopneumatique qui combine un vérin hydraulique et du gaz sous pression ou de l’air comprimé.Variables suivant les véhicules, les organes de la suspension automobile sont nombreux et certains comme les rotules, les biellettes, les silentblocs et les amortisseurs sont à changer quand ils vieillissent.Vous voulez commander les pièces détachées nécessaires ?Source de l’illustration : KYB Europe - Fournisseur d’amortisseur In order to permit the front wheels to swing to one side or the other for steering, each wheel is ported on a spindle which is part of the steering knuckle. and Types of Fuel Gauge with Its Working and Diagrams. In this type of suspension, each front wheel is independently supported by a coil, torsion bar, or leaf spring. This arrangement maintains the track width as the wheels rise and fall and so minimize tyre wear caused by the wheel scrubbing sideways.This type of suspension system is unusually for integral body construction because the loading points are widely spaced. In the second type, the coil spring is located between the upper and lower control arms.
The front end of the rod is of hexagonal shape to fit tightly into an opening in the lower control arm.Its rear reaction is also the hexagonal shape to fit tightly into an opening in an anchor attached to the frame cross member. Both the hangers are bolted to the frame. Track, wheel attitude and wheelbase remain unchanged throughout the rise and fail of the wheel.In the vertical guide suspension system, the kingpin is attached directly to the cross member of the frame. In Elliot type construction, the ends of the axle are forked to hold the steering knuckle extension between the ends. In the first type, the coil spring is located between the upper and lower control arms. Each end of the I-beam is supported by a leaf spring.This type of suspension system, a steel rod, known as a torsion bar, act as a spring to hold the upper and lower control arms parallel under load. Such springs are mounted in an inverted position parallel to and above the rear axle.

A seal hides the hexagonally shaped end of the torsion bar. This is an independent rear end suspension.In traverse leaf spring rear end suspension, a single transverse spring is used.
The wheel ends of the two I-beams are attached to the frame by radius arms, which prevent backward or forward movement of the wheels. Il existe d’autres systèmes que ceux cités mais qui ne sont pas ou peu utilisés en automobile comme les suspensions à bras tirés, télescopiques ou coulissantes. The spring weight is kept as less as possible, in order to improve the side of the vehicle. The torsion bar is designed to balance these forces so that the lower arm is kept at a designated height. The lower control arms have two points to the attachment to the car frame.
This suspension system known as the Mac Pherson System has slight rolling action and absorbs shocks easily.Trailing arm independent front suspension maintains constant track and wheel attitude with a slight change in wheelbase and caster angle. At (B) is shown a rear-end suspension using the radius arm. the automobile, which Gottlieb Daimler and Carl Benz developed independently of each other in 1886, established a completely new set of requirements compared with those associated with horse-drawn carriages – in particular where the suspension was concerned: it was necessary to cope with higher speeds, without endangering road users.
Fuel Gauge It allows for the relative motion between wheel and vehicle body; theoretically, a sus-pension system should reduce a wheel’s degree of freedom (DOF) from 6 to 2 on the rear axle and The torsion bar gets twisted due to the forces on the wheel assembly outer end of the lower control arm.
Each front wheel is supported at the end by a separate I beam. He is also an author and editor at theengineerspost.com The normal top link is replaced by a flexible, mounting and the telescopic damper acts as the kingpin. An automotive suspension connects a vehicle’s wheels to its body while supporting the vehi-cle’s weight. It can slide up and down, thus compressing and expanding springs.1.
