Embodiment Construction

[0026] figure 1 A control device 1 of a gearbox (not shown) is shown. The device 1 comprises a gear lever 2 and a gear lever support 3 . The gearbox is operated by means of a first control 4 and a second control 5 , which are coupled with control cables (not shown).

[0027] The gear lever support 3 comprises a housing 6 provided with side walls 7 and a bottom 8 which together define a cylindrical cavity 9 . The bottom 8 is substantially perpendicular to the side walls 7 .

[0028] The shift lever support 3 comprises a seat 10 and a ball 11, said seat being shown in detail in figure 2 superior. In the embodiment shown in the figures, the support 10 is divided into two identical parts, namely a lower part 12 and an upper part 13 . Each part 12, 13 comprises a pad 14 and a frame 15, image 3 An exploded perspective view of the liner and the frame is shown on FIG.

[0029] Liner 14 has the general shape of a ring and includes a number of utility surfaces in cross-section:...

Abstract

A gear lever support (3) comprising a housing (6) provided with an inner sidewall (7) and a bottom (8) together forming a cavity (9), said gear lever support (3) comprising a seat (10) housed in the cavity (9) provided with a bearing (14) mounted on a reinforcement (15) in contact with the housing (6), the bearing (14) being separated from the sidewall (7) by a clearance (31) and being separated from the bottom (8) by means of the reinforcement (15).

Description

technical field [0001] The invention relates to a gear lever with a sound filter system for a motor vehicle. Background technique [0002] To switch gear trains, the driver actuates the gear lever according to his needs, moving said gear lever from front to rear and from right to left. The gear lever needs to withstand the driver's use over the life of the vehicle. [0003] The rotational movement of the gear lever is managed at the location of the gear lever support. There are balls in the shifter support which are held securely between the pads. These pads participate in the smoothness of movement of the ball in the housing. These pads are themselves maintained in said gear lever support thanks to sealing gaskets made of a flexible material of the EPDM (ethylene propylene diene monomer) type. These gaskets are designed to be made of sufficiently deformable material to act as a sound filter. [0004] Under the successive stresses on the gasket, the gasket sags and a ga...
