Definitions
- TITLE VEHICLE WHEEL TRIANGLE, WITH ARTICULATION FITTED ON A FIXING ROD VIA A RING
- the invention relates to vehicles, generally of the automotive type, and more specifically to the wheel wishbones (or suspension) which equip some of these vehicles.
- certain vehicles generally of the automobile type, comprise, on the one hand, a chassis to which is coupled a front axle comprising two front right and left wheels each provided with a hub, and, on the other hand, two wheel wishbones coupled respectively to the frame and to the two hubs.
- wheel wishbones also called wishbones or wishbones
- the first end is intended to be coupled to the hub of a vehicle front wheel.
- the second end is provided with a first articulation which is intended to be coupled to the chassis of the vehicle.
- the third end comprises a fixing rod to which is coupled a second articulation which is housed for rotation in a recess of a coupling part intended to be fixedly secured to the frame.
- the fixing rod comprises a stop which prevents the second articulation from translating, and is attached, by welding or screwing, to the third end, as described in particular in patent document WO-A-2010105340. This not only imposes to carry out an assembly operation, but also to manage stocks, transport and storage of fixing rods.
- the attachment rod is an integral part of the main part, and a stopper, preventing the second joint from translating, is attached by welding to the non-free end of the attachment rod.
- the fixing rod having a circular section, the immobilization of the second articulation in relation to it must be done by a press fit using a press. In addition, we are forced to perform an additional operation to weld the stop.
- One of the aims of the invention is therefore to improve the situation.
- a wheel (or suspension) triangle comprising a main part comprising:
- a third end comprising a fixing rod to which is coupled a second articulation housed in rotation in a recess of a coupling part intended to be fixedly secured to the frame.
- - It comprises a ring having a transverse section having a second shape allowing its fitting without possible rotation in this first passage, and provided with a second passage allowing its fitting without possible rotation on the fixing rod.
- the wheel triangle according to the invention may have other characteristics which can be taken separately or in combination, and in particular:
- the fixing rod may comprise an elongate rib defined by stamping, and may have at the level of this elongate rib a transverse section having a third shape.
- the second passage has a transverse section having a fourth shape homologous to this third shape;
- the elongated rib can extend into the third end
- the fixing rod may comprise a groove defined in negative of the elongated rib and in which is partially housed an added reinforcement intended to increase the rigidity of the fixing rod;
- the added reinforcement can, for example, be made of steel
- the ring can, for example, be made of steel, aluminum or plastic;
- the first and second shapes can be rectangular.
- the invention also proposes a vehicle, optionally of the automobile type, and comprising, on the one hand, a chassis to which is coupled a front axle comprising two front right and left wheels each provided with a hub, and, on the other hand, two wheel wishbones of the type shown above and coupled respectively to the frame and to the two hubs.
- a vehicle optionally of the automobile type, and comprising, on the one hand, a chassis to which is coupled a front axle comprising two front right and left wheels each provided with a hub, and, on the other hand, two wheel wishbones of the type shown above and coupled respectively to the frame and to the two hubs.
- FIG. 1 schematically illustrates an embodiment of a triangle wheel according to the invention, during assembly.
- the aim of the invention is in particular to provide a triangle wheel (or suspension) TR intended to equip a vehicle, and with A2 articulation
- the triangle wheel (or suspension) TR is intended to equip a vehicle of the automotive type, such as a car, for example.
- the invention is not limited to this type of land vehicle. Indeed, the invention relates to any type of land vehicle comprising a chassis to which is coupled a front axle comprising two front right and left wheels each provided with a hub to be coupled to a wheel triangle, itself coupled. to the chassis.
- a wheel triangle TR comprises, once assembled, at least one main part PP, a ball joint LR, first A1 and second A2 joints, a coupling part PC, a fixing rod TF and a BA ring.
- the main PP part has a generally triangular shape, hence the name wheel triangle, and therefore includes first E1, second E2 and third E3 ends. It is for example made of metal, such as for example a steel. Furthermore, it is preferably carried out by
- the first end E1 is intended to be coupled to a hub of a wheel of a vehicle.
- a ball joint LR which is attached, for example by screwing, as illustrated without limitation in FIG. 1.
- the second end E2 is provided with the first articulation A1, which is intended to be coupled to the chassis of the vehicle.
- this first articulation A1 can comprise a cylinder of the silentbloc® type of rubber (possibly synthetic) or of plastic. It will be noted that the first articulation A1 can be secured to the second end E2 directly, or indirectly via a fastening part which is attached under the latter (E2).
- the third end E3 comprises a flattened TF attachment rod to which the second articulation A2 is coupled. It will be understood that the fixing rod TF is an integral part of the main part PP, of which it extends the third end E3.
- the second articulation A2 is housed for rotation in a recess EA (adapted for this purpose) of the coupling part PC, which is intended to be fixedly secured to the chassis of the vehicle, for example by screwing.
- this second articulation A2 comprises a first passage P1 which has a transverse section having a first non-circular shape (to prevent rotation).
- This second articulation A2 has a cylindrical shape so as to be able to rotate in a cylindrical-shaped recess EA of the coupling part PC. It can, for example, be of the rubber silentbloc® type
- the PC coupling part can, for example, be made of metal. Thus, it can, for example, be made of aluminum or steel.
- This PC coupling part may, for example, be in the form of a hollow cylinder with a lateral tab allowing it to be fixed to a part of the frame, as illustrated without limitation in FIG. 1.
- the ring BA has a transverse section which has a second shape allowing it to be fitted without possible rotation in the first passage P1 of the second articulation A2.
- this BA ring is provided with a second passage P2 which allows it to be fitted without possible rotation on the fixing rod TF.
- the BA ring cannot be rotated relative to the fixing rod TF because the latter (TF) is flattened, and the second joint A2 cannot be rotated relative to the BA ring, the second articulation A2 cannot therefore be rotated relative to the fixing rod TF.
- TF fixing rod
- the main part PP is stamped so as to have raised peripheral edges RP and extending to an ET end (not free) of the fixing rod TF in order to define an anti-translation stop. for the BA ring and the second A2 joint. This advantageously avoids having to attach an anti-translation stopper at the ET end by welding.
- the anti-translation stop thus defined by the free ends of the two peripheral flanges RP, is in fact produced during the stamping operation of the main part PP.
- the fixing rod TF can comprise an elongate rib NL defined by stamping.
- This elongated NL rib is intended to increase the rigidity of the fixing rod TF and the retention (anti-rotation) of the BA ring.
- the fixing rod TF has at the level of this elongated rib NL a transverse section having a third shape
- the second passage P2 of the ring BA has a transverse section which has a fourth shape homologous to this third shape.
- the third and fourth forms being homologous (that is to say substantially identical), the retention (anti-rotation) of the BA ring relative to the TF fixing rod is further increased.
- the elongated rib NL in order to further reinforce the rigidity of the fixing rod TF, it is advantageous for the elongated rib NL to extend into the third end E3, as illustrated without limitation in FIG. 1.
- the fixing rod TF can comprise a groove defined in negative of the elongate rib NL and in which is partially housed an added reinforcement which is intended to increase the rigidity. of the fixing rod TF.
- this added reinforcement can be made of steel.
- this added reinforcement can, for example, be secured to the fixing rod TF by welding or gluing.
- the BA ring can, for example, be made of steel, aluminum or plastic. It will also be noted, as illustrated without limitation in FIG. 1, that the first and second shapes, of the cross sections respectively of the first passage P1 and of the ring BA, can, for example, be rectangular. But other cheeses preventing rotation can be considered.
