Embodiment Construction

[0035] figure 1 The front of the motor vehicle 1 is shown on the top. The vehicle 1 includes a powertrain 2 provided with an air conditioning compressor 3 . Said air-conditioning compressor 3 comprises a shaft (not shown) on which means 4 for transmitting motion and filtering are mounted. Said device 4 is driven by a drive belt 5 .

[0036] An orthogonal reference frame XYZ is defined relative to the vehicle 1, which includes three two-by-two perpendicular axes, namely:

[0037] - an axis X defining a horizontal longitudinal direction coincident with the general direction of movement of the vehicle 1 ,

[0038] - an axis Y defining a horizontal transverse direction and together with the axis X defining a horizontal plane XY,

[0039] - An axis Z defining a vertical direction perpendicular to the horizontal plane XY.

[0040] The device 4 is described in detail below. refer to figure 2 , said device 4 comprises a first rotating element (hereinafter referred to as pulley...

Abstract

The invention relates to a device (4) for transmitting rotary motion and filtering vibrations, comprising a first rotary element (6) and a second rotary element (37) coupled to said first rotary element, said coupling This is implemented by a primary damping element (33) defining a first filter stage capable of filtering vibrations, wherein the coupling is also implemented by a secondary damping element (36) defining the second filter stage. The coupling is configured such that rotation of the first rotary element drives rotation of the primary damper element, which drives rotation of the secondary damper element, which in turn drives the rotation of the secondary damper element. rotation of the second rotating element, and the static stiffness of the first filter stage is at least ten percent less than the static stiffness of the second filter stage.

Description

technical field [0001] The present invention relates to the field of motor vehicles, and more particularly to devices for transmitting motion and filtering. Background technique [0002] Devices for transmitting motion are widespread on motor vehicles. This type of device exists in gearboxes. The means for transmitting the movement are used, for example, to obtain an output rotational speed different from the input rotational speed. [0003] The transfer of motion can generate jolts and vibrations that reduce the life of the mechanical parts of the motor vehicle. These vibration hazards and noise hazards are also felt by the user. [0004] In order to avoid the aforementioned disadvantages, the German document with publication number DE102009000014 describes a device for transmitting motion and filtering vibrations. The device includes a first rotary element and a second rotary element coupled to the first rotary element. The coupling is carried out by means of a series...
