Definitions
- the present invention relates to suspensions in particular for a motor vehicle and more particularly - but not exclusively - to four wheels.
- the traditional solution is to add an anti-roll bar per axle. In addition to the fact that the number of components is increased, it results in additional stiffness to the wheel when it is stressed alone to overcome an isolated obstacle.
- the Bertin patent FR 2 563 301 proposed a device insensitive to rolling motion, composed of a transverse elastic blade comprised between two rigid end parts.
- the Bertin patent FR 2,600,016 installs the prestressed blade in a support structure then assembled to the vehicle.
- the Bertin patent FR 2 624 446 reduces the number of components and erases the perverse effect mentioned above by a law of progressive stiffness.
- this solution requires - in return - a delicate interlocking at each end of the blade.
- any transverse blade solution has the major drawback of hampering the installation of the engine block between the wheels of the axle it serves.
- Such an architecture then requires: -or to position the engine block in cantilever, which has in particular the consequence of increasing the moment of inertia of pitching at the expense of comfort, -or to move the engine block towards the passenger compartment , to the detriment in particular of the space allocated to the occupants of the vehicle and the quality of treatment of the frontal impact.
- the architectures of traditional suspensions during the relative movements of the wheels relative to the vehicle, produce significant forces at the level of the front block and the rear block which require a high structural rigidity in torsion and in bending. This results in a limitation of the possibilities of reducing the mass of these parts which penalizes the dynamic behavior, the security and the energy consumption.
- the treatment of the shock can be entrusted - at least partially - to known lightweight and deformable materials, a simplification of the front and rear blocks is possible, to the benefit of the mass of the vehicle.
- pivots and elastic supports traditionally used can confer - in the context of known architectures - only flexibility limited by the need to maintain an acceptable geometry.
- a suspension must filter as much as possible the vibrations resulting from the rolling of the tires on the ground.
- the known architectures connect the suspension to the vehicle structure by two stages of flexible connections via an intermediate cradle which, however, does not contribute to the anisotropy of the stiffness of the assembly thus formed.
- the present invention proposes to provide a suspension device which overcomes these drawbacks.
- the elastic suspension structure according to the invention symmetrical with respect to the vertical plane containing the longitudinal axis of the vehicle, flexible mainly vertically and secondarily horizontally, consists of at least three flexible arms, linked together at one end where they merge, the vertically projected surface of said structure being inscribed inside the polygon joining the free ends of the adjacent arms, each of said ends of the suspension structure being linked - directly or indirectly - to a wheel support.
- Each arm of the elastic structure according to the invention is, in general, linked - between its end linked to the other arms and its end linked to the wheel support - to the passenger compartment of the vehicle.
- it is a flexible connection with anisotropy of stiffness offering mainly a freedom of movement in rotation around an axis close to a horizontal perpendicular to the arm at this place of connection and, secondarily, a certain freedom of movement suitably chosen on each of the other five axes, in particular in translation along its axis of articulation and in rotation about perpendicular axes.
- This connection can in particular be produced in the form of a flexible pivot, an oblong support, a couple of elastic supports or any other elastic device with stiffness anisotropy.
- the ratio of the width to the thickness of the current section of each arm advantageously has at least a minimum in the vicinity of the place of connection of the arm to the passenger compartment of the vehicle and a maximum in the vicinity of the place where the arms merge .
- each arm in horizontal projection on a vertical plane perhaps - under strong vertical load - substantially straight from its end connected to the wheel support to its place of connection to the passenger compartment of the vehicle. In conditions of high vertical load, this results - in the portion of the arm between its end linked to the wheel support and its connection to the vehicle interior - the cancellation of torsion due to a horizontal force applied at its end linked to the wheel support.
- each arm may comprise - at its central part, which is between its end linked to the other arms and its connection to the passenger compartment of the vehicle - one or more transverse ribs.
- At least one additional stiffness - spring or preferably stopper made of elastomeric material, in particular containing a cavity filled with gas under pressure advantageously adjusted to the speed and / or the load of the vehicle - can be installed between the passenger compartment of the vehicle and the central material. of the suspension structure, which is limited by its connections to the passenger compartment of the vehicle.
- the suspension structure can be linked to the passenger compartment of the vehicle by means of a rigid cradle in its plane, symmetrical with respect to the vertical plane containing the longitudinal axis of the vehicle, flexible to the warping and more rigid with respect to stresses other than warping, hollowed out in particular in the manner of a substantially rectangular frame whose sides can however be curved and whose current section advantageously decreases towards the junction points which support the connections to the suspension structure between which the cradle is connected to the vehicle by four connections, two connections called “longitudinal” because located in the longitudinal plane of symmetry of the cradle and two connections called “transverse” because located on a transverse axis which intersects said plane of symmetry at a point suitably chosen at substantially equal distance from the liai longitudinal sounds.
- these are flexible connections with stiffness anisotropy, each conferring freedom of rotation around respectively longitudinal and transverse axes and also offering a certain freedom of movement suitably chosen on each of the other five axes, in particular by translation along the articulation axis and in rotation around perpendicular axes.
- connection can in particular be produced in the form of a flexible pivot, an oblong support, a couple of elastic supports or any other elastic device with stiffness anisotropy.
- the suspension structure and the cradle according to the invention can be made of any material whose ratio of the resistance to fatigue to the flexural modulus is high, preferably in composite material - in particular glass-epoxy - made up of fibers oriented at least two directions embedded in synthetic resin. Characteristics of the invention are specified with reference to FIGS. 1 to 10 for embodiments relating to four-wheeled vehicles:
- FIG 1 is a longitudinal sectional view along B2-B2 'of Figure 2 of a suspension structure according to the invention shown in the silhouette of a vehicle and Figure 2 is a top view in section along Al -Al 'of fig. 1.
