Definitions

• the invention relates to the technical sector of equipment for motor vehicles, and more particularly relates to a device for fixing a gear lever knob of a gearbox.
• control levers for the passage and selection of speeds are always equipped at their free ends with a knob for the operation of said lever.
• Various technical solutions have been proposed to ensure the attachment of this knob.
• the knob may be fitted on a deformation made at the end of the lever during its machining, in combination with retaining ribs.
• the pommel is force-fitted with a relatively large effort to obtain an effective hold over time. With this solution, it is difficult to see if the pommel is sufficiently fitted.
• the fixing device defined in this patent, comprises a plastic part added by overmolding at the end of the upper part of the lever. Said piece has fixing arrangements adapted to ensure the fitting of the knob and its disassembly.
• the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
• the problem to be solved by the invention is to be able to dampen the possible shocks that can suffer the pommel.
• a device for fixing a lever knob of a gearbox for a motor vehicle which has means capable of allowing the limited coaxial displacement of the knob relative to the lever under the effect of a shock exerted on the pommel, in order to cushion the shock.
• the invention finds a particularly advantageous application in the case of a device for fixing a shift lever of a gearbox comprising a plastic insert overmolded at the end of one end of said lever, said insert being shaped for allow the attachment of the pommel, under a clipping effect, and disassembly, as is apparent from the teaching of FR 2725166.
• the insert has arrangements capable of allowing its limited coaxial displacement relative to the lever under the effect of a shock exerted on the pommel, in to dampen said shock.
• the arrangements are constituted by a space formed in the extension of the portion of the insert overmolded at the end of the lever and coaxially with said portion to allow said displacement.
• the space may be constituted by a recess or a through hole.
• the insert is overmolded at the end of the lever in combination with retaining means adapted to allow the coaxial displacement of said insert under the effect of impact.
• the insert has external arrangements capable of ensuring the fitting of the knob with a low insertion effect and a large withdrawal effort.
• the lever is of round section.
• FIG. 1 is a longitudinal sectional view of the pommel fastening device according to the invention, the knob being shown in a position called normal use;
• FIG. 2 is a view corresponding to Figure 1 showing the displacement of the entire knob relative to the lever under the effect of a shock exerted on said pommel.
• the body of the lever (1) is for example of solid cross section, in particular of round section.
• the end (la) of the lever is arranged to receive by overmoulding a plastic insert (2) shaped to allow the fitting under a clipping effect of a knob (3) also of any known and appropriate type.
• the end (la) of said lever may have recessed and raised asperities, a knurling or other, to allow overmolding of the insert (2) and its securing.
• the insert (2) has a hollow portion (2a) overmolded on the end portion (1a) of the lever (1).
• This hollow portion (2a) is extended by a space (2b) to allow the limited coaxial displacement of the insert (2) and consequently of the entire knob (3) fitted on said insert, relative to the lever (1). ).
• Such a displacement can result, for example, from a shock exerted on the knob (3).
• the displacement of the insert assembly (2) / knob (3) has the effect of damping the shock.
• This space (2b) can be constituted by a recess or a through hole (figures of the drawings).
