Problems solved by technology

But at high rpm, the elastic parts deform due to centrifugal force, creating an air gap between these elastomer parts and the spokes or teeth, which creates noise when the torque changes
In addition, the large number of components in this known device is also disadvantageous

Embodiment Construction

[0016] The embodiment of the device 2 for transmitting torque shown in the figure is part of the driving mechanism of the automobile air-conditioning compressor 4, which includes a pulley 6 driven by the automobile internal combustion engine (not shown) through a belt drive mechanism (not shown) , a hub 10 that is non-rotatably connected to the compressor shaft 8 of the air-conditioning compressor 4, and a substantially ring-shaped vibrator that is arranged between the pulley 6 and the hub 10 and that is non-rotatably connected with the hub 10 A damping element 12, the vibration damping element 12 serves to transmit the torque from the pulley 6 to the hub 10 and at the same time serves to damp vibrations.

[0017] The vibration damping element arranged between the pulley 6 and the hub 10 is not limited to the annular form as shown in Fig. 1 and Fig. 2, but may for example be star-shaped or other. Furthermore, the described or claimed device for transmitting torque is not limit...

Abstract

The invention relates to a device for transmitting a torque from a belt pulley (6) to a hub (10) of a group to be driven, especially a compressor (4), for example an air-conditioning compressor of a motor vehicle. The inventive device comprises a vibration damping element (12) arranged between the belt pulley (6) and the hub (10). According to the invention, the vibration damping element (12) is connected to the hub (10) in a fixed manner on the inner periphery thereof, and is engaged with the belt pulley (6) in a positively locking manner on the outer periphery thereof.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 . Background technique [0002] Modern air conditioner compressors for automobiles or other mobile applications typically have a pulley that is driven by the internal combustion engine through a belt drive. The torque exerted by the belt drive on the pulley is usually transmitted by the pulley to a hub which is connected in a rotationally fixed manner to the compressor shaft of the air-conditioning compressor. The function of the vibration damping element arranged between the pulley and the hub is to dampen the vibration of the crankshaft of the internal combustion engine or the belt drive mechanism and the vibration caused by the load change of the air conditioner compressor. In addition, an overload protector is generally provided on the torque transmission path between the pulley and the compressor shaft, which can irreversibly cut off the power transmission when overload occurs...
