    Go-kart with variable orientation clevis compression system, corresponding mechanism and chassis.
    1. Field of the invention
    The field of the invention is that of go-karts. The invention applies in particular to the field of competition karts, but also finds applications on all types of karts, and in particular leisure karts, for example rental.
    More specifically, the invention relates to the mounting of rockets, each carrying a wheel, on the chassis of the kart.
    2. Prior art
    Conventionally, the rocket carries a pivot ring, which is housed between two wings of a clevis secured to the chassis. A bolt secures the ring to the clevis.
    It is known practice to place, on this screw, adjustment eccentrics, generally an upper eccentric, placed on the external face of the upper wing of the yoke, and a lower eccentric, placed on the external face of the lower wing of this screed.
    The displacement of one and / or the other of the eccentrics makes it possible to slightly move the screw, and consequently the pivot ring. Thus, by acting on the upper eccentric, we modify the casing, and by acting on the lower eccentric, we modify the camber.
    Generally, with such a system, the recovery of forces is done on the lower part of the yoke, and this mounting can prove to be relatively imprecise and / or insufficiently effective.
    There is therefore a need to improve in the kart chassis the mounting of the rockets on the chassis, as well as the adjustment of the chassis and / or the camber.
    3. Presentation of the invention
    This is achieved thanks to a kart comprising at least two rockets each carrying a wheel and each connected to a yoke secured to the chassis of said kart, a securing screw passing through two bores provided for this purpose in said yoke and a pivot ring extending at one end of said rocket, placed between two parallel wings of said yoke, an upper eccentric and a lower eccentric being mounted on said screw, respectively, on the outer faces of said wings.
    According to the invention, the kart comprises, between said wings of the yoke, the assembly successively comprising the following elements:
    an upper hemispherical washer; an upper male hemispherical wedge; said pivot ring;
    a lower male hemispherical wedge; a lower hemispherical washer, and a first hemisphere is mounted between the head of said screw and said upper eccentric and a second hemisphere is mounted between a tightening nut of said screw and said lower eccentric.
    Thus, the invention proposes a self-aligning system with variable orientation clevis compression. The system forms a swivel spacer, the yoke being mounted in compression.
    In this way, the force recovery takes place on the two wings of the yoke, and not only on the lower yoke.
    Once assembled, said set of elements can be immobilized in position, after adjustment of said eccentrics, when said screw is tightened on its nut.
    In a particular embodiment, said upper eccentric is configured to allow adjustment of the casing between 0 and 6 ° and in that said lower eccentric is configured to allow adjustment of the camber between 0 and 6 °.
    According to a particular embodiment of the invention, said hemispherical wedges can take different thicknesses, so as to allow an adjustment in height of said kart.
    The invention also relates to an eccentric mechanism for kart as such, intended to secure a rocket to a clevis, comprising a securing screw passing through two bores provided for this purpose in said clevis and a pivot ring extending to a end of said rocket, placed between two parallel wings of said yoke, an upper eccentric and a lower eccentric being mounted on said screw, respectively, on the outer faces of said wings.
    Such a mechanism comprises, between said wings of the yoke, the assembly successively comprising the following elements:
    an upper hemispherical washer; an upper male hemispherical wedge; said pivot ring;
    a lower male hemispherical wedge; a lower hemispherical washer, and a first hemisphere is mounted between the head of said screw and said upper eccentric and a second hemisphere is mounted between a tightening nut of said screw and said lower eccentric.
    The invention also relates to kart chassis comprising at least two mechanisms of this type.

    Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment, given by way of simple illustrative and nonlimiting example, and of the appended drawings among which:

    Figures 3a and 3b show respectively the sections CC and BB of Figures 2a and 2b;
    Figure 4 shows all of Figures 2a and 2b, top view.
    5. Description of particular embodiments
    As indicated above, the invention proposes a new approach for assembling a rocket 11 to a yoke 12 of a kart chassis, from a set of elements, a particular embodiment of which is illustrated in the figure
    1.
    Outside the upper wing 121 of the yoke 12 are placed an upper hemisphere 13 a , then the upper eccentric 14 a . The upper sphere 13 a is housed in the central opening of the upper eccentric 14 a .
    Always from top to bottom, we then meet the upper wing 121 of the yoke 12 then, under this wing 121, a female hemispherical washer 15 a (sometimes called by abuse of language spherical washer), then a male upper hemispherical shim 16 a .
    We then meet the pivot ring 111 of the rocket 11, then symmetrically at the top:
    a lower male hemispherical wedge 16b; a lower female hemispherical washer 15b; the lower wing 122 of the yoke 12;
    the lower eccentric 14b; a half-sphere 13b.
    According to the embodiments illustrated, the washers are made of steel, and the eccentrics are made of aluminum. Of course, other materials can be used.
    This assembly is put into compression by the tightening of a bolt, comprising a clamping screw 17, for example a shouldered screw, which passes through all of the elements listed above, and which cooperates with a nut 18, for example of the Nylstop type. (registered trademark) spherical.
    When all the elements are put in compression using the bolt formed by the screw and the nut, there is a “sandwich” system mounted in compression. This set forms a swivel spacer, which is particularly effective. In particular, this approach ensures a resumption of effort on the wings 121 and 122, that is to say in the upper part and in the lower part, as illustrated by the arrows F s i and F s2 d '. on the one hand, and the arrows Fji and F i2 in FIG. 2a.
    As can be seen in FIG. 2a and in FIG. 2b, the invention allows adjustment of the eccentric, while retaining an optimized alignment and good efficiency, in all situations.
    The sectional views of FIGS. 3a and 3c illustrate the position of the various constituent elements, depending on whether the eccentric is in a position at zero angle (FIG. 3a) or in a position forming an angle at 6 ° (FIG. 3b).
    As can be noted in FIG. 3b, a plane / plane connection of the upper female spherical washer 15 a is obtained, despite the eccentricity.
    It can be noted that, in these figures, the upper wedge 16 a has a thickness greater than that of the lower wedge 16β. It is of course possible to modify these thicknesses, to place a lower shim thicker than the upper shim, or to use shims of the same thickness. This allows you to adjust the height of the chassis, without having to modify the other elements.
    Figure 4 illustrates the system seen from above. A distinction is made between the upper eccentric 14 a , the position of which can be modified, to adjust the socket.
