Definitions

• the present invention relates to a rear part of a vehicle which has a wheel arch, a spar which extends essentially along the longitudinal axis of the vehicle, at the edge of the wheel arch, a suspension element which extends
• a suspension element which extends essentially along the transverse axis of the vehicle and means for fixing a first end of the suspension element to a structural part of said rear part.
• a suspension element is constituted by a stabilizing bar for a semi-rigid rear axle, commonly called a Panhard bar, which extends between the two rear beams, with pivot-type fixing means which secure a first end of the bar. Panhard to a rear axle suspension arm and a second end to the spar positioned opposite the suspension arm.
• Such an assembly of the Panhard bar limits its length to the distance between the suspension arm and the beam positioned opposite the suspension arm, which limits the road behavior of the vehicle and also degrades comfort.
• the device according to the invention overcomes these drawbacks.
• it indeed comprises a rear part of a vehicle which includes a wheel arch, a spar which extends essentially along the longitudinal axis of the vehicle, at the edge of the wheel arch, a suspension element. which extends essentially along the transverse axis of the vehicle and of the means for fixing a first end of the suspension element to a first structural part of said rear part, such that the first structural part is positioned in the passage of wheel.
• the first structural part forms a yoke.
• the yoke is extended under the beam by a second structural part which forms a U.
• the yoke and the second U-shaped structural part are open towards the bottom of the vehicle.
• the second structural part is extended by a third structural part which extends along a side wall of the beam which is positioned opposite the wheel arch.
• the yoke and the second structural part comprise at least one part which has two thicknesses of sheets.
• the upper part of the first structural part extends above the lower part of the part of the beam on which said first structural part is secured.
• the suspension element is formed by a Panhard bar.
• the first end of the suspension element is fixed to the first structural part by fixing means of the pivot type.
• the present invention also relates to a vehicle which comprises a rear part with at least one of the preceding characteristics.
• FIG.1 shows a sectional side view of part of the rear structure of the vehicle according to the invention.
• a frame of reference linked to the normal direction of movement of a vehicle is used.
• the term front indicates a positioning towards the front of the vehicle and the rear term indicates a positioning towards the rear of the vehicle.
• the longitudinal axis corresponds to the normal axis of travel of the vehicle and the transverse axis to an axis perpendicular to the longitudinal axis included in the plane of movement of the vehicle.
• Figure 1 shows a sectional side view of part of the rear structure 1 of the vehicle.
• the rear part 1 of a vehicle has a wheel arch 2, a beam 3 which extends essentially along the longitudinal axis of the vehicle, at the edge of the wheel arch 2 and a suspension element 4 which extends essentially along the transverse axis of the vehicle.
• the suspension element 4 forms a Panhard bar with a central cylindrical part 42, a first end 41 of which is fixed by fixing means 5 to a first part 1 1 of the rear structure 1 of the vehicle.
• the first part 1 1 of the rear structure 1 of the vehicle is positioned in the wheel arch 2. To do this, the first part 1 1 of the rear structure 1 of the vehicle forms a yoke.
• the yoke 1 1 is open only on two sides; a first lateral side for the passage of the central cylindrical part 42 of the suspension element 4 and towards the bottom of the vehicle.
• the yoke 1 1 is extended by a second structural part 12 under the beam 3.
• the second structural part 12 has a U-shape open towards the bottom of the vehicle.
• a third structural part 13 extends the second structural part 12 and goes up along a lateral edge 31 called the inner side of the beam 3, positioned opposite the wheel arch 2.
• the second structural part 12 and the yoke 1 1 have a double thickness of sheets to ensure a sufficient level of rigidity.
• the fastening means 5 are of the pivot type with a pivot axis 51 secured to the yoke 11 and a cylindrical ring 52 secured to the first end 41 of the suspension element 4.
• a cylindrical shim 53 is interposed between the pivot axis 51 and the ring 52.
• the yoke 1 1 can also, depending on the desired positioning for the first end 41 of the suspension element, go up towards the top of the vehicle in the wheel arch 2 relative to to the second structural part 12.
• the purpose of such an assembly being to have the cylindrical central part 42 of the suspension element 4 which is as long as possible and as high as possible.
• the second end of the suspension element 4 is integral with a suspension arm of a rear axle of the semi-rigid type vehicle, as known from the state of the art (the second end of the suspension element suspension, the suspension arm and the rear axle of the vehicle not being shown).
• the suspension element 4 does indeed have a length greater than the distance between a suspension arm and the beam 3 positioned on the opposite side of said arm, without encroaching on other parts of the rear part of the vehicle, in particular on the chest.
