Description

Technical Field

[0001] This invention claims priority to French application No. 2001876, filed on February 26, 2020, the contents of which (text, drawings and claims) are incorporated herein by reference.

[0002] The present invention relates to a vehicle including an additional stop that facilitates the assembly of a suspension damper in a wheel arch, the wheel arch including a filling slot for filling a fuel container in the same location, which restricts the accessibility required for assembling the suspension damper.

[0003] More specifically, the present invention relates to an additional stop comprising at least one contact surface for the upper portion of the suspension damper when the damper is assembled in the vehicle, the assembly being adapted to reduce running noise when the upper portion of the damper is integrally connected in the wheel arch. Background Technology

[0004] In the case of telescopic dampers arranged substantially perpendicular to the rear of the vehicle, it is known that in order to assemble the vehicle, the lower ends of these dampers are fixed to the rear axle of the vehicle in a preparation position in a first step.

[0005] In the next step, the vehicle body is lowered onto the rear axle, and then the upper end of the damper is fixed to the vehicle body.

[0006] For telescopic dampers including integrated expansion springs, an apparatus is known from document FR3064972A1 for securing an additional stop in a wheel arch, the additional stop forming a mating surface that serves the upper portion of the suspension damper when the upper portion of the damper is integrally connected to the wheel arch by a fixing component (e.g., a fixing screw).

[0007] After the upper portion of the damper is secured, the additional stop cannot be removed, which causes the additional stop to remain in place in contact with the upper portion of the damper. This generates various noises in the wheel arches during vehicle operation, which can be heard by the vehicle's passengers. Summary of the Invention

[0008] The purpose of this invention is particularly to avoid these problems of the prior art.

[0009] According to the present invention, this disadvantage is overcome. In fact, the present invention includes a vehicle comprising a wheel arch, a suspension damper positioned in the wheel arch, a fixing member for integrally connecting an upper portion of the suspension damper to the wheel arch, and an additional stop member, the additional stop member including at least one contact surface, the at least one contact surface being for the upper portion of the suspension damper when the damper is assembled in the vehicle, such that the damping member is positioned between the at least one contact surface and the upper portion of the suspension damper.

[0010] According to a first feature of the invention, the damping component includes a portion made of foam, silicone, or rubber, which enables a gap of less than 5 mm to be maintained between at least the mating surface and the upper portion of the damper, the gap preferably being 2 mm.

[0011] According to a second feature of the invention, the damping component is integrally connected to at least the mating surface or to the upper portion of the damper.

[0012] According to a third feature of the invention, the additional stop includes an elongated central portion having two mating surfaces for the upper portion of the suspension damper, the two mating surfaces being positioned along the central portion.

[0013] According to the first and second embodiments of the present invention, the additional stop is either screwed or riveted along the lateral fixed wall of the wheel arch, or welded along the lateral fixed wall of the wheel arch.

[0014] According to the second embodiment, the additional stop includes an upper portion positioned at a distance from the lateral fixed wall of the wheel arch, the distance being adapted to allow the additional stop to remain in position when the additional stop is welded along the lateral fixed wall of the wheel arch, the weld being formed by an electric welding point.

[0015] The present invention also relates to an additional stop member comprising at least one mating surface for an upper portion of a suspension damper when the damper is fitted in such a vehicle, such that the at least one mating surface includes a damping member adapted to be positioned facing the upper portion of the suspension damper.

[0022] refer to Figures 1 to 3 The image shows the rear portion of the vehicle, which includes a rear wheel arch 1, a telescopic suspension damper 2 positioned in the rear wheel arch 1, a fixing component 3 for integrally connecting the upper portion 21 of the damper 2 to the rear wheel arch 1, and an additional stop 4.

[0023] exist Figure 1 The diagram shows, for example, views of an additional stop 9 positioned in the wheel arch 1 and a suspension damper 2.

[0024] exist Figure 2 The diagram shows, for example, a detailed cross-sectional view of an additional stop 4 positioned in the wheel arch 1 and a suspension damper 2.

[0025] exist Figure 3 The image shows a view of the additional stop 4 before it is positioned in the wheel arch 1.

[0026] The rear wheel arch 1 includes a vertical lateral metal plate 11 that closes the bottom of the rear wheel arch 1 and terminates at the bottom at a small longitudinal beam, for example, as known in the prior art.

[0027] The lateral metal plate 11 includes a support member 12 for supporting the upper portion 21 of the damper 2.

[0028] The support member 12 is tilted downward at an angle of approximately 15° relative to the vertical portion of the lateral metal plate 11.

[0029] The support member 12 includes two first openings for receiving two fixing screws 5 for integrally connecting the upper part 21 of the damper 2 to the rear wheel arch 1.

[0030] The support member 12 includes two second openings for two rivets 6, which are located above two first openings for fixing screws 5, and the two second openings are used to integrally connect the additional stop 4 into the wheel arch 1.

[0031] As in Figure 1 More specifically, a filling groove 7 for filling the fuel container is positioned in the rear wheel arch 1.

[0032] The filling groove 7 includes a generally horizontal first portion 71 and a vertical second portion 72, the first portion covering a portion of the support member 12, the second portion descending parallel to the suspension damper 2, and covering a portion of the additional stop member 4.

[0033] The filling groove 7 is positioned at a minimum distance from the vertical metal plate 11, which is approximately 15 mm.

[0034] exist Figure 2 More specifically, the upper portion of the suspension damper 2 includes a cylindrical retaining sleeve 23.

[0035] A fixed shaft 24 is positioned in the sleeve 23. The fixed shaft includes a cylindrical central portion 241 positioned in the sleeve 23 and two flat arms 242, which are respectively located in the extension of each of the two ends of the cylindrical central portion 241 and protrude from each side of the sleeve 23.

[0036] Each arm 242 includes an opening 243 adapted to cooperate with each of the two first openings of the support 12 to receive two fixing screws 5.

[0037] A sleeve 25 made of an elastomer is inserted between the sleeve 23 and the cylindrical central portion 241 of the fixed shaft 24 to filter vibration.

[0038] As in Figure 3 More specifically, the additional stop 4 has an elongated central portion 41 with two branches 42 at its two ends, which extend downward and terminate at two planar mating surfaces 43.

[0039] Two openings 44 are formed along the additional stop 4 to allow two rivets 6 to pass through, which enables the additional stop 4 to be integrally connected to the wheel arch 1.

[0040] Damping components 8 are positioned between the two mating surfaces 43 and each of the two arms 242 of the upper portion 21 of the suspension damper 2. These damping components typically include at least one part made of foam, silicone, or rubber.

[0041] For this purpose, the damping member 8 creates a gap of less than 5 mm between each of the two mating surfaces 43 of the additional stop 4 and each of the two arms 242 of the upper portion 21 of the suspension damper 2. This gap is preferably 2 mm and corresponds to the compressed thickness of the damping member 8.

[0042] The damping component 8 can be fixed either along the two mating surfaces 43 of the additional stop 4 or along the two arms 242 of the upper portion 21 of the suspension damper 2.

[0043] During assembly, first locate the additional stop 4, and then install the filling groove 7.

[0044] The upper portion 21 of the suspension damper 2 is positioned to fit against the two mating surfaces 43 of the additional stop 4.

[0045] The fixing screw 5 is finally screwed in to complete the assembly, so that the additional stop 4 comes into contact with the upper part 21 of the suspension damper 2.

[0046] The damping component 8, positioned between the two mating surfaces 43 of the auxiliary stop 4 and the upper portion 21 of the suspension damper 2, is used here to prevent mechanical noise between the two mating surfaces 43 of the auxiliary stop 4 and the upper portion 21 of the suspension damper 2 during vehicle operation.

[0047] Figure 4 and Figure 5 A second embodiment of the additional stop 9 is shown.

[0048] exist Figure 4 The diagram shows, for example, a partial cross-sectional detail of an additional stop 9 positioned in the wheel arch 1 and a suspension damper 2.

[0049] exist Figure 5 The image shows a view of the additional stop 9 before it is positioned in the wheel arch 1.

[0050] The essential difference of this second embodiment lies in the fixing mode in which the additional stop 9 is fixed in the wheel arch 1, wherein two electrical welding points 10 are used.

[0051] Therefore, the support member 12 (for the vertical metal plate 11 of the wheel arch 1) no longer includes two first openings for the two fixing screws 5 to pass through.

[0052] The additional stop 9 includes an upwardly extending extension 91 in which a pre-holding opening 92 is formed.

[0053] The two pre-holding openings 92 allow the additional stop 9 to remain in place when the two electric welding points 10 are applied.

[0054] Since the additional stop 9 has a flat form positioned as close as possible to the support 12 of the wheel arch 1, the extension 91 is offset from the support 12 by means of the inclined middle portion 93 forming a gap.

[0055] The spacing of the extensions 91 of the additional stop 9 should be less than 15mm so as not to contact the filling groove 7.
