Definitions

  • the invention relates to a wheel suspension device for mobile vehicles and mobile vehicles provided with this device, in particular for motorcycles.
  • the suspension devices produced so far on the front of motorcycles generally consist of two suspension tubes directly connecting the axis of the steering wheel to the frame or chassis of the motorcycle indirectly by means of mounting on the 'pivoting axis of direction secured to the frame or chassis of the motorcycle by the steering column supporting the pivoting axis.
  • the sliding of the suspension tubes requires an angle of inclination relative to the ground facing an obstacle as well as for the stability of the motorcycle; on the other hand the sliding of the tubes in the vertical plane relative to the ground is braked by the inclination of these tubes requiring in this case for good sliding that they are perpendicular to the direction of the force.
  • the object of the present invention is to remedy these drawbacks and to this end relates to a wheel suspension device for mobile vehicles and mobile vehicles provided with this device, in particular for motorcycles comprising one or two devices which can be mounted symmetrically on the side and on the other side of the wheel and be connected together so as to have only one suspension element.
  • Each device comprising a first link fixed to the axis of rotation of the wheel connecting by its articulated free end a second link; this first, link also receiving the oscillating end of a third link at a fixed point located between the two ends of the longitudinal axis of the first link connecting in an articulated way a fourth link connecting in an articulated way the free end of the second liaison; the assembly forming a deformable parallelogram, the 3rd or 4th connection receiving between its ends or beyond these on its axis or outside its longitudinal axis one end of an articulated suspension element, device characterized in that the frame or chassis of the vehicle receives at a fixed point directly or indirectly by means of a pivoting assembly the articulation of a suspension element connecting an articulated and oscillable parallelogram and also receives for its command, at a fixed point at beyond the axis of articulation of the suspension element the parallelogram me at a fixed point articulated with one of the connections between, with or beyond its axis of articulation by its extension.
  • the inter-axis of the connection of the wheel axle at the point of articulation of the connection directly or indirectly connecting the frame or chassis of the vehicle will both be common to this eatre-axis.
  • the wheel axle can receive a fixed or pivoting wheel support and be connected by a linkage to the steering control of the mobile vehicle.
  • two sliding connections between them can be implemented in order to stiffen the assembly connecting by a free end in an articulated manner the wheel axle, its other end will be directly or indirectly secured to the frame or chassis of the vehicle, in alignment with the axis of oscillation of the parallelogram.
  • the sliding links between them may include a piston and be used to move air, oil or a combination in order to return a certain force to the rear suspension device and vice versa.
  • the invention is shown by way of nonlimiting example in the single attached drawing which is a partial and schematic view of the invention applied to the pivoting steering axis which is itself attached to the frame or chassis of the motorcycle. .
  • the present invention is concerned with the production of an angle wheel suspension device. constant chassis allowing to face important obstacles and readjust in proportion to the more or less vertical centrifugal force 'with respect to the ground with the advantages of excellent damping and minimum maintenance.
  • This wheel axle 12 leaves the link 21 connecting by the articulation 24 the link 20 connecting in a fixed articulated r-anointed the articulation axis 16 integral with the assembly from which starts from this same articulation axis 16, the articulation of the connection 8 connecting by the articulation 14 the connection 9 connecting by its articulated free end 25 the longitudinal axis of the link 21 at a fixed point, the wheel 13 rotating around the wheel axle 12, the brake flange 23 secured to the wheel axle, 12 and the end of the link 21, the link 22 holding the brake flange 23 at a fixed point 26 connecting the link 21 at a fixed point 27, a suspension element 7 starting from a fixed articulated point 17 secured to the assembly connecting the link 8 at a fixed articulated point 15 ensuring the suspension of the vehicle , the return spring 29 of the device.
  • the wheel 13 moves by pushing the link 9 pax its link 21 which pushes the link 3 which pushes the suspension element 7 but is guided along a linear path and parallel to the pivot axis 2 by its articulated end 24 pulling the link 20 moving in opposition to the link 8, to obtain this result l between axes of connections 20, 21 and 9 is common, the guides 10 and 11 can be used to ensure the rigidity of the assembly, or even include a hydraulic or combined gas system to interact with the suspension rear by hose 28.
  • connection generally designates a rigid connection such as a tube for example.
  • the device of the invention can be implemented on any vehicle h. wheel suspension.
