Problems solved by technology

[0003] However, when the vehicle is in neutral and no torque is being transmitted through the transmission system, the gaps that exist between the splines are prone to noise due to collisions between the splines
The noise may be transmitted to the interior of the vehicle and impair the comfort of the occupants

Embodiment Construction

[0030] In all figures, the same elements or elements performing the same function have the same reference signs.

[0031] The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference is to the same embodiment, or that a feature is only applicable to a single embodiment. Simple features of different embodiments may also be combined and / or interchanged to provide other embodiments.

[0032] In the following description, the terms "first", "second", etc., eg "first part", "second part", are used as a simple way of numbering elements to indicate and distinguish similar but not systematic elements. This numbering does not imply any priority of one element over another, and such designations could easily be interchanged without departing from the scope of the present description. The numbering also does not imply any order in time.

[0033] In the following description, the terms "axial", "r...

Abstract

The invention relates to a torque transmission device (1, 30) designed to be arranged between an engine and a gearbox of a motor vehicle, said torque transmission device (5, 30) comprising a splined hub (5, 31), said The splined hub is designed to be pushed onto the complementary splined shaft (3) of the gearbox, wherein the splined hub (5, 31 ) comprises an annular groove ( 15,45), and wherein, the device further comprises elastic elements (17,19,21,47), said elastic elements are designed to be arranged in said annular grooves (15,45) and configured to cooperate with said shifting The splined contacts of the splined shaft (3) of the box.

Description

technical field [0001] The invention relates to the field of torque transmission devices, such as torque dampers, in particular torque transmission devices for motor vehicles. Background technique [0002] A motor vehicle transmission system includes a number of devices, in particular an engine and a gearbox that are rotationally coupled relative to each other. This mechanical connection is achieved, for example, by splines, one element comprising a splined shaft and the other comprising a complementary splined hub. [0003] However, when the vehicle is in neutral and no torque is being transmitted through the transmission system, the gaps that exist between the splines are prone to noise due to the collision between the splines. This noise can be transmitted to the interior of the vehicle and impair the comfort of the occupants. [0004] It is therefore appropriate to find a solution which reduces or eliminates the noise generated in the area of ​​the complementary spline...
