    [0001] "DEVICE FOR CONTROLLING A GEARBOX OF A MOTOR VEHICLE USING A SPEED CHANGE LEVER WITH NOISE DAMPING ARRANGEMENTS". The present invention relates to a device for controlling a manual gearbox of a vehicle, including automotive. In known manner, such a device comprises a gearshift lever which is pivotally mounted at its lower end around a fixed point in a housing or fixed support supporting the lever, according to a determined speed grid. The housing or fixed support can be secured to the floor of the vehicle between the two front seats thereof or implanted in the dashboard of the vehicle. [0004] US Pat. No. 8,522,637 describes a device for controlling a gearbox of a motor vehicle whose gearshift lever is equipped with a trigger for locking the vehicle's reverse gear and which can be operated against an elastic return means to allow the lever to engage reverse. This gearshift lever is also equipped with a member for damping the noise occurring during the return of the lever and its trigger to the locking position of the reverse gear. However, the implementation of the gearshift lever of the noise damping member leads to an extremely complex structure of the lever, thereby burdening the manufacturing costs of the external control device of the gearbox. In addition, the noise damping member of this known lever does not effectively absorb the vibrations produced by a lever when it occupies a position of passage of a speed other than that of the reverse gear. The present invention aims to overcome the above drawbacks of the known device for controlling a gearbox of a motor vehicle. For this purpose, according to the invention, the device for controlling a gearbox of a vehicle, in particular a motor vehicle, by means of a shift knob lever mounted on a fixed and equipped support. on the one hand a reversing latch trigger can be operated against a resilient biasing means to allow the lever to engage reverse and on the other hand at least one member of noise damping, in particular during the return of the lever and the trigger to the locking position of the reverse, is characterized in that the trigger is secured to the lever being movable in translation along it to the pommel against the elastic return means from its reverse lock position to its position allowing the lever to engage reverse, which trigger comprises two trigger portions located respectively close to the fixed support e and the knob, the lever comprises, integral with it, two damping members of noise and vibrations in the form of O-rings and the two parts of triggers comprise two frustoconical internal seats respectively bearing on the two bodies of damping under the action of the resilient return means in the opposite direction to the pommel when the lever and the trigger are in their locking position of the reverse gear. Preferably, each damping member is housed in a groove of the lever radially projecting therefrom. Advantageously, the circular edge of each groove of the lever, which abuts the corresponding damping member under the action of the biasing means exerted on the frustoconical inner seat resting on this member, has a larger diameter. to the diameter of the other circular edge of the groove. Advantageously, the elastic return means is a helical compression spring coaxially mounted on the lever being in prestressed support between the lever and one of the two trigger portions. Preferably, the compression coil spring is housed in the gate portion close to the fixed support. Advantageously, the helical compression spring is in prestressed support between an annular stop ring secured to the lever and an internal shoulder of the trigger portion close to the fixed support. The trigger portion close to the fixed support comprises, integral in translation thereof, an outer projection coming in lateral support on an abutment fixed to the fixed support to prohibit the engagement of the reverse gear and which can be raised during the translational movement of the trigger to the pommel and brought into abutment by the displacement of the lever to allow the engagement of reverse. The invention also relates to a gearshift lever for a vehicle, in particular a motor vehicle, comprising a knob at one of its ends, a locking trigger of the reverse gear and at least one noise damping member , and which is characterized in that the trigger is integral with the lever being movable in translation along it to the pommel against an elastic return means, which trigger comprises two trigger portions located respectively at proximity of the pommel and opposite the latter, the lever comprises, integral with it, two damping members of noise and vibrations in the form of O-rings and the two parts of triggers comprise two frustoconical internal seats in support , in the rest position of the trigger, respectively on the two damping members under the action of the elastic return means in the opposite direction to the pommel. The invention finally relates to a motor vehicle, which is characterized in that it is equipped with a device for controlling a gearbox by means of a shift knob lever and such that previously defined. The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying drawings given solely by way of example illustrating a embodiment of the invention and in which: - Figures 1 to 3 show in perspective a shift lever for a motor vehicle and respectively occupying a neutral position, a position prohibiting passage of reverse gear and a position allowing passage of reverse gear; - Figure 4 is a longitudinal sectional view of the shift lever of Figures 1 to 3 equipped with damping means of noise and vibration and occupying the locking position in reverse; FIG. 5 is an enlarged view of the circular V-shaped portion of FIG. 4; FIG. 6 is an enlarged view of the circular portion VI of FIG. 4; - Figures 7 and 8 are views similar to those of Figures 5 and 6 and showing the trigger of the lever raised to its position allowing the engagement of the reverse of the vehicle. The external control device of a manual gearbox of a motor vehicle shown in Figures 1 to 3 comprises a housing or fixed support 1 which can be secured to the floor of the vehicle between the two front seats thereof and a shift lever 2 supported by the fixed housing 1 being pivotally mounted by its lower end 3 about a fixed point consisting of a ball 4. The shift lever 2 can be moved by its end upper having a knob 5 according to a determined speed grid. The lower end portion 3 of the lever 2 is coupled to the passage members and gear selection, not shown and known per se. The combination of transverse and longitudinal displacements of the knob 5 of the lever 2 thus defines the gear grid comprising a selection line or substantially transverse dead center and several substantially longitudinal passage lines. Figure 1 shows the shift lever 2 at its position corresponding to the neutral line. The shift lever 2 is equipped with a trigger 6 for locking access to the vehicle reverse selection line and can be operated against an elastic return means, which will be defined later, to allow the movement of the lever in the transverse and longitudinal directions of selection and passage of reverse. Figure 2 shows the trigger 6 of the shift lever 2 at a position prohibiting access to the reverse selection line while Figure 3 shows the trigger 6 at its position of engagement of the step back. Referring also to Figures 4 to 8, according to the invention, the trigger 6 is integral with the shift lever 2 being movable in translation along it to the knob 5, against the resilient biasing means 7, from its reverse lock position to its position allowing the shift lever 2 to engage the rear step. The trigger 6 comprises two trigger portions 8, 9 axially spaced from each other along the lever 2 and located respectively close to the knob 5 and the fixed housing 1. The two trigger portions 8.9 are connected to each other by an intermediate portion 30. In the case where the shift lever 2 is hingedly mounted on the floor of the vehicle between the two front seats and occupies a substantially vertical position at its stitch position death, the trigger portion 8 is said to be higher and the trigger portion 9 is said to be lower. The upper trigger portion 8 comprises at least one radially outer ring 10 that can be manually grasped by the driver to lift in translation the trigger 6 to the knob 5 against the elastic return means 7 to allow the lever 2 to engage reverse gear. The lower trigger portion 9 comprises, integral in translation thereof, an outer projection 11 coming in lateral support on a stop 12 secured to the upper face of the fixed housing 1 to prevent the lever 2 from engaging reverse gear as shown in FIG. 2. [0030] By raising the trigger 6 towards the knob 5, the lower trigger portion 9 is also moved upwards to disengage the external projection 11 of the stop 12 to allow the engagement of the reverse gear as shown in FIG. 3, the external projection 11 bearing on the abutment 12 under the action of the elastic return means 7. Preferably, the elastic return means 7 is constituted by a helical compression spring housed in the lower trigger portion 9 coaxially with the lever 2 being in prestressed support between an annular locking ring 13 secured to the lever 2 and an internal shoulder 14 of the portion of gâc lower end 9 located below the ring 13, so that the coil spring 7 exerts a restoring force directed downwards on the lower trigger portion 9 and, therefore, on the trigger 6. [0032] Alternatively , the resilient return means 7 could be housed in the upper trigger portion 8 being mounted prestressed between an inner shoulder of this portion and an annular ring integral with the lever 2 above this shoulder. The shift lever 2 comprises two damping and vibration damping members 15, 16 housed respectively in the upper and lower portions 8 of the upper trigger 8 being integral with the lever 2. [0034] More precisely, the two damping members 15, 16 are in the form of O-rings respectively housed in two upper grooves 17 and lower 18 of the lever 2 radially projecting therefrom. The two trigger portions 8, 9 comprise two frustoconical internal seats 19, 20 respectively bearing on the two damping members 15, 16 under the action of the elastic return means 7 in the opposite direction to the knob 5 when the lever 2 and trigger 6 occupy their reverse lock position. On the lower circular edge 17a, 18a of each groove 17, 18 of the lever 2 and defining with the upper circular edge 17b, 18b the width of the groove 17, 18, abuts the corresponding damping member 15 , 16 under the action of the elastic return means 7 exerted on the frustoconical inner seat 19, 20 resting on the damping member 15, 16. The lower circular edge 17a, 18a of the groove 17, 18 has a diameter greater than the diameter of the upper circular edge 17b, 18b of this groove. Thus, at the position of the trigger 6 of the shift lever 2 shown in Figures 4 to 6 and at which the trigger 6 prohibits access to the reverse selection line, the elastic return means 7 ensures the plating of the frustoconical inner seats 19, 20 of the upper and lower trigger parts 8, 9 on the two damping members 15, 16 and this plating is still maintained even in the case of manipulation of the shift lever to select and pass a speed other than reverse gear. The frustoconical shape of the inner seats 19, 20 of the upper 8 and lower 9 trigger parts in cooperation with the damping members 15, 16 considerably reduces the transmission to the vibration lever 2. Figures 7 and 8 show the situation in which the trigger 6 has been raised to allow access to the reverse selection line and show that the upward movement of the trigger 6 relative to the lever 2 has compressed the elastic return means 7 and the frustoconical internal seats 19, 20 are disengaged from above the damping members 15, 16. When the shift lever is in the reverse gear engagement position, the projection 11 of the lower trigger portion 9 is held in abutment on the stop 12 by the elastic return means 7 which is expanded relative to its position of Figure 8. [0039] To disengage the lever 2 from its reverse position , the trigger 6 is again raised towards the knob 5 against the restoring force of the elastic means 7 in order to disengage the external projection 11 from above the stop 12 and the lever is moved to its position ofneutral point shown in Figure 1 with release of the trigger 6. When returning the trigger 6, the two frustoconical inner seats 19, 20 of the upper and lower trigger portions 8, 9 are supported by the action of elastic return 7, respectively on the two damping means 15, 16, which thus ensure the absence of any noise and / or vibrations. The gearshift lever described above of the invention thus virtually eliminate the noise and vibration of the trigger when returning to the stop and also during its return during the movement of the lever to its position reversing lock. The lever thus designed also eliminates noise and vibration when manipulated to make changes in speed other than that of reverse.
