Definitions
- the invention relates to the technical sector of equipment for motor vehicles and more particularly relates to the selection control gearboxes, including mechanical. It will be recalled, for a better understanding of the following description, that the selection and shifting control is effected by means of a lever mounted with angular displacement capacity in a support case generally fixed at the level of the cabin of the motor vehicle.
- This housing has arrangements for mounting with multidirectional displacement capability of the lever, in particular in the form of a spherical joint such as a ball joint.
- the lower end of the lever has arrangements, to ensure generally with the return elements, the selection and shifting via cables or bars.
- the hinge joint of the lever is secured to a selection finger engaged free rotation in the deflection element and selection so that the angular tilting of the lever causes, concomitantly, the angular pivoting of the deflection and selection element mounted with articulation capability with respect to an axis.
- the axis is generally equipped with a pin spring mounted prestressed, and whose branches are biased separately, under the effect of the angular tilting of the lever. It is also known that it is necessary to provide arrangements for selecting the speeds in order to avoid unexpectedly switching on the reverse, particularly when the lever is tilted to the right to reach the alignment. with the 1-2 speed lane or swing to the left to align with the 5-6 speed lane.
- control lever can be equipped with a reversing locking system in the form of a trigger operable by hand to allow the angular movement of the lever.
- a reversing locking system in the form of a trigger operable by hand to allow the angular movement of the lever.
- the trigger When the trigger is not actuated, it is possible to orient and tilt the lever corresponding to the selection, and the passage of the first speed for example. In this position of non-actuation of the trigger, it is not possible to steer more importantly the lever to select the reverse gear. It is therefore necessary, to engage reverse, to act on the trigger to release a stop allowing greater movement to the gear lever.
- These arrangements can be found at the 5-6 speed lane.
- This reverse lock trigger solution obviously entails significant additional costs. Still with the same objective of avoiding any unwanted engagement of the reverse gear, it has been proposed to create a hard point at the control lever.
- This hard point may be located at the shift lane 1-2 towards the MA lane or at the shift lane 5-6 to the MAR lane.
- this hard point can be created by a boss that presents the return element and selection and cooperating with a spring blade.
- the return and selection of the return member is effected by means of a pin spring mounted prestressedly about the pivot axis of said return and selection member.
- a mounting device in a support housing, a deflection element and selection subject to a control lever of a mechanical gearbox of a motor vehicle which comprises, at the axis of articulation of said element, a cam profile that has a portion of said element, said profile cooperating with an elastic return member to create, depending on the angular positioning of the selection element and of the zone of interest of the cam profile, a resistance of variable intensity to create a hard point corresponding to the selection and the passage of the reverse gear II thus results from these characteristics, that the return member in combination with the cam profile of a part of the deflection and selection element, ensures both the hard point function for engaging the reverse gear and allows the return to neutral position said return and selection element.
- the elastic return member is a leaf spring fixed in a plane substantially tangent to the axis of pivoting of the deflection element, on a portion of the support housing receiving the control lever. From these characteristics, it is particularly important to observe that this spring blade can participate actively to ensure, in an efficient and rational way, the synchronization between the neutral position of the control lever and the neutral position of the gearbox.
- the blade is mounted, before attachment, with displacement capacity in translation, to allow synchronization between the neutral position of the control lever and the gearbox.
- the blade has an oblong slot cooperating with a fastener on the part of the support housing.
- FIG. 1 is a perspective view of an embodiment given as an indication but in no way limiting of a support case with the control lever and the return and selection element,
- FIG. 2 is a partial view on a larger scale of the deflection and selection element
- FIGS. 3 to 10 show the position of the deflection and selection element as a function of the angular tilting of the lever corresponding to a selection of a passage of passage of speed namely:
- FIG. 3 shows the return and selection element in the neutral position of the lever
- FIG. 4 is a partial view on a larger scale corresponding to FIG. 3,
- FIG. 5 shows the return and selection element corresponding to a tilting of the lever along the passageway 5-6 of the gears
- FIG. 6 is a partial view on a larger scale corresponding to FIG. 5,
- FIG. 7 shows the positioning of the deflection and selection element corresponding to a position of the lever according to the 1-2 velocity corridor
- FIG. 8 is a partial view on a larger scale corresponding to FIG. 7,
- FIG. 9 shows the passage and selection element in position of the lever corresponding to the hard point for selection of the reverse gear
- FIG. 10 is a partial view on a larger scale. corresponding to Figure 9,
- FIG. 1 shows an example of a housing (B) of a mechanical gearbox receiving with articulation capacity a control lever (1) for the passage and the selection of speeds by means for example of cables.
- a control lever (1) for the passage and the selection of speeds by means for example of cables.
- editing with the ability to multidirectional movement of the lever (1) is effected by means of a ball joint (2) which may have a finger (3) which serves as an axis for coupling a return and selection element (4).
- the angular tilting of the lever (1) to the left or to the right with respect to a neutral position causes, by means of the selection finger (3), the angular pivoting of the deflection and selection element (4). ) with respect to an axis of rotation (5).
- the aim is to create a hard point for the selection and the passage of the reverse gear, either at the level of the gears 1-2, or at the level of the gears 5-6 .
- the return and selection element (4) has at its pivot axis (5) a cam profile (6) adapted to cooperate with an elastic return member (7) to create, depending on the angular positioning of the return and selection element (4) and the relevant zone of the cam, a hard point at the lever for the passage of the reverse gear.
- the cam profile (6a) has a zone (a) corresponding to the neutral position of the lever, FIGS. 3 and 4, an area (b) corresponding to the position of the lever along the velocity corridor 5-6 (FIGS. 6), an area (c) corresponding to the tilting of the lever on the corridor 1-2 ( Figures 7 and 8) and a zone (d) corresponding to a tilting of the lever to the reverse ( Figures 9 and 10).
- the elastic return member (7) is constituted by a leaf spring fixed in a plane tangent to the axis of pivoting (5) of the return (4), on a fixed part (8) of the support housing (B) receiving the control lever (1).
- the free end of the blade (7) has arrangements, for example in the form of a roller (7a), adapted to cooperate with the cam profile (6a) of the return and selection element (4). .
- the lever (1) is actuated and is tilted angularly causing the selection finger (3) to cause the angular pivoting (arrow F) of the return and selection element and the positioning of the profile zone. in cam (b) with the end (7a) of the blade (7).
- lever (1) is tilted in the opposite direction to that of Figures 5 and 6 to select the corridor 1-2 speeds.
- the return and selection element (4) pivots angularly about its axis (5) (arrow F1) so that only the cam profile region (c) is in contact with the end (7a) of the blade (7).
- cam profile (6a) it is important to determine the cam profile (6a) in order to adapt at will the force that it is necessary to exert on the lever (1) and consequently on the selection element and depending on the desired passageway.
- leaf spring (7) which cooperates with the cam profile of the selection and return element, which ensures the recall of this element, thereby eliminating the use of the return spring mounted according to the state of the art prestressed around the pivot axis of the selection and return element.
- the particular mounting device of the control and selection element (4) also makes it possible to ensure, in a simple and effective manner, the synchronism between the neutral position of the control lever (1 ) and the gearbox. This synchronism is very important and generally requires complex implementation means.
- the spring blade (7) for returning the deflection and selection element (4) is pre-fixed in the portion (8) of the casing with limited translation displacement capability.
- the fixing of the blade (7) on the portion (8) of the support is effected by means of a screw (9) engaged in an oblong slot formed in the thickness of said blade (7).
