  SUSPENSION INDEPENDANTE DES ROUES AVANT DIRECTRICES DES VEHICULES

ROUTIERS. 

  
L'invention concerne une suspension indépendante des roues

  
avant directrices des véhicules routiers, en particulier automobiles, dans lesquels le guidage et la suspension des roues sont

  
assurés par les extrémités de ressorts à lames superposés et

  
fixés au châssis. Les extrémités de ces ressorts à lames sont

  
assemblées par des axes verticaux sur lesquels les roues peuvent

  
être orientées.

  
Conformément à l'invention, chaque roue est suspendue sur

  
deux demi-ressorts à lames qui sont fixées sur un support trans-

  
versal du châssis . Avantageusement, les ressorts sont montés de

  
manière à former un angle aigu avec le sens de marche en s'écar-

  
tant l'un de l'autre vers l'arrière. 

  
On obtient ainsi les avantages suivante:

  
I.- L'espace compris entre les roues avant est en substance dégagé des dispositifs de guidage et de suspension des roues. On peut donc monter le moteur dans cet espace.

  
2.- Lorsque l'on freine les roues avant,leurs tambours de freins transmettent un fort couple de rotation aux fusées d'essieux pouvant pivoter sur leurs axes de direction. Si les ressorts

  
sont disposés transversalement au sens de la marche, ils subissent, sous l'effet de ce couple, une torsion très défavorable. Mais si les ressorts sont inclinée suivant un angle aigu par rapport au sens de marche, ce couple de rotation ne provoque en fait, dans les ressorts, que des efforts de compression et de traction.

  
3.- Aux extrémités du support transversal, on peut monter commodément le pare-chocs du véhicule.

  
4.- Les ressorts sont plus facilement accessibles pour le graissage et le nettoyage que dans les dispositions connues.

  
Un exemple de réalisation de l'invention est représenté schématiquement dans le dessin annexé, sur lequel:
Fig.l est une vue en plan de la partie antérieure du chassis d'un véhicule automobile pourvu d'une suspension conforme à l'invention; Fig.2 est la vue en élévation correspondant à la fig.l.

  
Le support tubulaire médian 1 du châssis du véhicule est relié à une traverse avant 2, aux extrémités de laquelle sont attachés deux demi-ressorts à lames 3. Les extrémités de ces ressorts sont introduites et assujetties chacune dans un sabot

  
ou bride 7 fixé sur la traverses 2. Les extrémités externes des ressorts superposés 3 sont assemblées par des axes 4 sur les-

  
 <EMI ID=1.1> 

  
des sabots de freins qui se placent à l'intérieur des tambours de freins 8 fixés sur les roues. Lorsque l'on freine sur les roues avant, les tambours de freins 8 qui tournent cherchent à entraîner avec eux les fusées 6. Il en résulte qu'un effort est exercé sur les ressorts 3, qui consiste essentiellement en une compression du ressort supérieur et une extension du ressort inférieur. 

  
La traverse 2 porte avantageusement le pare-chocs 6 du véhicule, et ce par l'intermédiaire d'étriers élastiques 9.

  
Les trajets dans lesquels les fusées 5 sont guidées relativement au châssis 1-2 sont à peu près des arcs de cercle, se trouvant dans des plans perpendiculaires aux blocs 7. Comme chacun de ces plans forme un angle aigu avec le tube longitudinal médian 1, la distance entre les fusées et le plan vertical et longitudinal médian du véhicule augmente quand les roues sont élastiquement relevées. Ceci signifie que le centre momentané est plus élevé que dans le cas du guidage des roues parallèlement à ce plan.

  INDEPENDENT SUSPENSION OF FRONT STEERING WHEELS OF VEHICLES

ROADS.

  
The invention relates to a wheel independent suspension

  
front steering of road vehicles, in particular automobiles, in which the guidance and suspension of the wheels are

  
ensured by the ends of superimposed leaf springs and

  
attached to the frame. The ends of these leaf springs are

  
assembled by vertical axles on which the wheels can

  
be oriented.

  
According to the invention, each wheel is suspended on

  
two leaf half-springs which are fixed on a trans-

  
versal of the frame. Advantageously, the springs are mounted from

  
so as to form an acute angle with the direction of travel by deviating

  
both from each other backwards.

  
The following advantages are thus obtained:

  
I.- The space between the front wheels is essentially free from the wheel guiding and suspension devices. We can therefore mount the engine in this space.

  
2.- When the front wheels are braked, their brake drums transmit a high torque to the axles which can pivot on their steering axles. If the springs

  
are arranged transversely to the direction of travel, they undergo, under the effect of this torque, a very unfavorable torsion. But if the springs are inclined at an acute angle with respect to the direction of travel, this torque does in fact cause, in the springs, only compressive and tensile forces.

  
3.- At the ends of the transverse support, the vehicle bumper can be easily mounted.

  
4.- The springs are more easily accessible for lubrication and cleaning than in the known arrangements.

  
An exemplary embodiment of the invention is shown schematically in the accompanying drawing, in which:
Fig.l is a plan view of the front part of the chassis of a motor vehicle provided with a suspension according to the invention; Fig.2 is the elevational view corresponding to fig.l.

  
The median tubular support 1 of the vehicle frame is connected to a front cross member 2, to the ends of which are attached two half leaf springs 3. The ends of these springs are introduced and each secured in a shoe.

  
or flange 7 fixed on the crosspieces 2. The outer ends of the superimposed springs 3 are assembled by pins 4 on the-

  
 <EMI ID = 1.1>

  
brake shoes which are placed inside the brake drums 8 fixed to the wheels. When the front wheels are braked, the rotating brake drums 8 seek to drive the spindles 6 with them. As a result, a force is exerted on the springs 3, which essentially consists of compression of the upper spring and an extension of the lower spring.

  
The cross member 2 advantageously carries the bumper 6 of the vehicle, and this by means of elastic brackets 9.

  
The paths in which the rockets 5 are guided relative to the frame 1-2 are roughly arcs of a circle, lying in planes perpendicular to the blocks 7. As each of these planes forms an acute angle with the longitudinal middle tube 1, the distance between the rockets and the vertical and longitudinal median plane of the vehicle increases when the wheels are resiliently raised. This means that the momentary center is higher than in the case of guiding the wheels parallel to this plane.
