Definitions
- the present invention claims the priority of French application 2212194 filed on November 23, 2022, the content of which (text, drawings and claims) is here incorporated by reference.
- the present invention relates to a vehicle which comprises a chassis on which is fixed a rear axle provided with a crossmember.
- the invention relates more particularly to a rear axle which comprises on each side of the crossmember a longitudinal suspension arm comprising, in the rear part, a wheel hub and, in the front part, an articulation.
- the articulation makes it possible to secure the front part of the suspension arm to the chassis.
- the chassis includes a mounting cup mounted on a rear axle support connected to the chassis.
- the joint is housed partly in the fixing cup and includes fixing lugs for fixing it to an upper part of the fixing cup.
- Electric vehicles include batteries resulting in excess weight compared to a thermal vehicle.
- the aim of the invention is therefore to overcome the drawbacks of the prior art by proposing a vehicle which comprises a chassis provided with a more resistant fixing cup.
- the invention thus relates, in its broadest acceptance, to a vehicle comprising a chassis on which is fixed a rear axle comprising a crossmember and a suspension arm on each side of the crossmember.
- the suspension arm comprises, in the rear part, a wheel hub and, in the front part, a joint allowing the front part of the suspension arm to be secured to the chassis.
- the joint is fixed on a mounting cup mounted on a rear axle support connected to the chassis.
- the vehicle comprises a cup reinforcement positioned between the fixing cup and the rear axle support.
- the invention thus provides a vehicle which comprises a chassis provided with a more resistant fixing cup.
- the cup reinforcement prevents deformation of the fixing cup and prevents the joint from separating from the fixing cup.
- the fixing cup comprises a hollow bottom comprising an opening in which the joint is partially housed.
- the cup reinforcement comprises an orifice in which the hollow bottom is partially housed.
- the orifice of the cup reinforcement is delimited by a first peripheral border surrounding the hollow bottom of the fixing cup.
- the cup reinforcement is welded to the fixing cup.
- the opening of the hollow bottom of the fixing cup is delimited by a second peripheral border.
- the first peripheral edge of the cup reinforcement is welded to the second peripheral edge of the fixing cup at a first end of the cup reinforcement and at a second end of the cup reinforcement, opposite the first end.
- the first peripheral edge comprises a rear edge running along an internal face of the hollow bottom.
- the rear edge is positioned at the first end of the cup reinforcement.
- the first peripheral edge comprises a first side edge running along a first side wall of the hollow bottom and a second side edge running along a second side wall of the hollow bottom.
- the first one side border and the second side border are connected by a front border running along a front wall of the hollow bottom.
- the cup reinforcement completely surrounds the hollow bottom, ensuring great strength to the fixing cup.
- the rear edge of the cup reinforcement is fixed to a rear edge of the second peripheral edge of the fixing cup.
- the second side edge and the front edge of the first peripheral edge of the cup reinforcement are connected to a first fold connected to a second fold.
- the folds are positioned at the second end of the cup reinforcement.
- the first fold is welded to a first front edge of the second peripheral edge of the fixing cup.
- the first fold is perpendicular to the first side edge and extends towards the first front edge of the second peripheral edge of the fixing cup.
- the second fold is perpendicular to the first fold and extends in a direction opposite the hollow bottom.
- the rear edge of the first peripheral edge of the cup reinforcement is inclined relative to the first side edge and the second side edge of the first peripheral edge.
- the cup reinforcement is fixed on the rear axle support.
- FIG.1 schematically illustrates a transparent view of a part of a vehicle comprising a chassis provided with a fixing cup reinforced by a cup reinforcement, according to one embodiment of the invention
- FIG.2 schematically illustrates a detailed view from above of the fixing cup reinforced by the cup reinforcement of Figure 1;
- FIG.3 schematically illustrates a detailed view of the underside of the fixing cup reinforced by the cup reinforcement of Figure 1.
- Figure 1 illustrates a part of a vehicle 1 comprising a chassis 2 on which is fixed a rear axle 3 comprising a crossmember 4 and a suspension arm 5 on each side of the crossmember 4.
- front and rear are used in relation to the forward driving direction of the vehicle.
- the crosspiece 4 can be a deformable crosspiece.
- the suspension arm 5 comprises, in the rear part, a wheel hub and, in the front part 6, an articulation 7 making it possible to secure the front part 6 of the suspension arm 5 to the chassis 2.
- the fixing cup 8 comprises a hollow bottom 20 comprising an opening 21.
- the opening 21 of the hollow bottom 20 of the fixing cup 8 is delimited by a second peripheral edge 29.
- the joint 7 comprises a head 30 partially housed in the opening 21 of the hollow bottom 20 and two fixing lugs 31 extending on each side of the joint 7 and which are fixed on the second peripheral edge 29 of the fixing cup 8.
- the head 30 of the joint 7 faces an external face 37 of the hollow bottom 20 and distant from this external face 37.
- the fixing cup 8 is mounted on a rear axle support 9 fixed to the chassis 2.
- the second peripheral edge 29 extends from the opening 21 of the hollow bottom 20 towards the outside of the hollow bottom 20.
- the opening 21 of the hollow bottom 20 is formed by a first opening 33 delimited by a first peripheral edge portion 35 which is substantially parallel to a wall 38 of the rear axle support 9 on which the fixing cup 8 is mounted
- the opening 21 of the hollow bottom 20 is also formed by a second opening 34 delimited by a. second peripheral edge portion 36 which is inclined relative to the first peripheral edge portion 35.
- the two fixing lugs 31 of the articulation 7 are fixed on the first peripheral edge portion 35 by means of two fixing orifices 40 provided on each side of the first opening 33.
- the first peripheral edge portion 35 has a triangular shape and comprises a first front edge 27 and a second front edge 41 connected by a vertex 42, as illustrated in Figure 2.
- the head 30 of the joint 7 is housed partly in the first opening 33.
- the suspension arm 5 springs out through the second opening 34.
- the vehicle 1 comprises a cup reinforcement 10 positioned between the fixing cup 8 and the rear axle support 9.
- the cup reinforcement 10 is positioned under the fixing cup 8, on the side of an internal face 32 of the fixing cup 8.
