Embodiment Construction

[0028] exist figure 1 The vibration damping device 10 according to a first embodiment is shown in FIG. 2 for transmitting the rotational movement of the crankshaft (not shown) to the auxiliary unit (not shown) via a belt drive (not shown).

[0029] The damping device 10 has a hub 12 , a belt pulley 14 and a decoupling device 16 . The hub sleeve 12 and the belt pulley 14 are arranged concentrically to one another, the belt pulley 14 surrounding the hub sleeve 12 radially with a gap 18 around the circumference. Pulley 14 has a V-shaped relief 20 for receiving a belt or belt drive, not shown. The hub shell 12 is used to couple the damper device 10 to the drive end of the internal combustion engine, such as the crankshaft.

[0030] The decoupling device 16 is arranged in the gap 18 and connects the hub sleeve 12 and the belt pulley 14 to one another in a rotationally elastic manner. The decoupling device 16 has a first spring part 22 and a second spring part 24 , wherein the tw...

Abstract

The invention relates to a vibration damper (10) inlcuding a hub sleeve (12) and a belt wheel (14), which are connected to each other through a decoupling apparatus (16), for ensuring better vibration decoupling, the decoupling apparatus (16) has at least two springs (22, 24).

Description

technical field [0001] The invention relates to a damping device for a belt drive of an internal combustion engine and in particular to a decoupling pulley, comprising a hub sleeve and a pulley, wherein the pulley and hub sleeve are connected via the decoupling device. [0002] In motor vehicles with internal combustion engines, auxiliary units such as air-conditioning compressors or generators are driven via the crankshaft. The rotational movement of the crankshaft is then transmitted to the auxiliary unit via a belt drive by means of a damping device of the type mentioned in the introduction. [0003] The rotational variability of the crankshaft causes vibrations to be carried into the belt drive. For vibration isolation, a decoupling device is arranged between the hub sleeve and the pulley. Such dampers are also known as decoupled pulleys or decoupled torsional vibration dampers. The torsional rigidity of such a decoupling device is generally chosen such that the first e...
