Problems solved by technology

[0006] However, the disadvantage of this prior art arrangement is that only a constant torsional stiffness is defined by the provision of spring elements between the pulley and the hub.
In belt-driven generators, however, it is desirable to use devices with as low torsional stiffness as possible at low generator loads in order to decouple the generator from the belt drive to a large extent

Embodiment Construction

[0019] exist figure 1 shows a schematic sectional view of a device according to the invention for connecting a generator to a belt drive of an internal combustion engine. In this arrangement, a belt pulley 1 is guided in a rotatable manner relative to a hub 2 , which is mounted on a shaft 3 of a generator. In this case, pulley 1 is constructed in a manner known to those skilled in the art and is connected to the crankshaft of the internal combustion engine via a belt (not shown here). When the internal combustion engine is running, the pulley 1 is twisted via the belt drive, and the pulley 1 transmits this rotational movement indirectly to the hub 2 , thereby driving the generator via the shaft 3 . In order to achieve the transfer of rotational motion from the pulley 1 to the hub 2 while avoiding the introduction of rotational inhomogeneities into the generator drive, between the pulley 1 and the hub 2 and between the pulley 1 and the hub 2 and defined radially apart Arcuate...

Abstract

A device for connecting a generator to a belt drive of an internal combustion engine is provided, which includes a belt pulley (1) that is guided so that it can rotate relative to a hub (2) set on a shaft (3). At least one spring element is arranged between the belt pulley (1) and the hub (2) and connects the belt pulley (1) and the hub (2) to each other elastically for transferring rotational motion and here sets a relative rotation between the belt pulley (1) and the hub (2) corresponding to an effective torsional stiffness. The at least one spring element is placed with a defined movement play (s) with respect to the belt pulley (1) and / or the hub (2), in order to allow relative rotation through the movement play (s) in a first region (I) with a low torsional stiffness, while, in a second region (II), a high torsional stiffness can be generated by the at least one spring element.

Description

technical field [0001] The invention relates to a device for connecting a generator to a belt drive of an internal combustion engine, said device comprising a pulley which is guided so as to be able to rotate relative to a hub arranged on a shaft, wherein the pulley and the At least one spring element between the hubs elastically connects the pulley and the hub to each other to transmit a rotational movement, and a relative torsion between the pulley and the hub is achieved here corresponding to the effective torsional stiffness . Background technique [0002] In order to supply power to the complete vehicle power supply of the motor vehicle, a generator is usually arranged in the area of ​​the internal combustion engine, the generator is connected to the crankshaft of the internal combustion engine via a belt drive, and thus rotates when the internal combustion engine is running. This rotation generates the current required for operating the consumer and for charging the s...
