Problems solved by technology

[0006] However, this noise reduction member is placed on the gear lever, which leads to an extremely complex structure of the lever, thus burdening the manufacturing costs of the external control device of the gearbox
[0007] Furthermore, the known noise dampening members of the lever do not effectively absorb the vibrations generated by the lever when it occupies a shift position other than reverse gear

Embodiment Construction

[0024] Figure 1 to Figure 3 The illustrated external control device for a manual gearbox of a motor vehicle comprises a stationary housing or support 1 which can be seated with the vehicle floor at the two fronts of the vehicle and a gear lever 2 Integral between the chairs, said shift lever is supported by a fixed housing 1 while being fitted to pivot by its lower end 3 about a fixed point constituted by a ball joint 4 .

[0025] The gear lever 2 can be moved according to the determined gear grid by including the upper end of the handle 5 .

[0026] The lower end 3 of the lever 2 is coupled to not shown components for shifting and selecting gears, which are known per se.

[0027] The combination of lateral and longitudinal movements of the handle 5 of the lever 2 thus defines a gear grid comprising a substantially transverse selection or neutral line and several substantially longitudinal shift lines.

[0028] figure 1 The gear lever 2 is shown in a position corresponding...

Abstract

The present invention relates to a manual transmission device of a vehicle, particularly an automobile. The device is essentially characterized in that the lever (2) includes, rigidly connected thereto, two noise / vibration reduction members (15, 16) and two trigger portions (8, 9) including two inner frusto-conical seats (19, 20) that are respectively made to bear on the two noise / vibration reduction members (15, 16) by a resilient return means (7) when the lever (2) and the trigger (6) occupy the reverse gear locking position thereof. The invention is useful in manual motor vehicle gearboxes.

Description

technical field [0001] The invention relates to a device for controlling a manual transmission of a vehicle, in particular a motor vehicle. Background technique [0002] It is known that such a device comprises a gear lever fitted so as to be pivotable by means of the lower end of the lever around a fixed point in a fixed housing or a fixed support supporting the lever, in accordance with a grid defining the gears. in the file. [0003] Said stationary housing or stationary support may be integrated with the vehicle floor between the two front seats of said vehicle, or placed in the dashboard of the vehicle. [0004] Patent US8522637 describes a device for controlling the gearbox of a motor vehicle, the gear lever of which device is equipped with a vehicle reverse lock latch and said reverse lock latch can be manipulated against an elastic return member, to allow the lever to engage reverse gear. [0005] The gear lever is also equipped with a means to dampen the noise pr...
