Embodiment Construction

[0045] figure 1 A schematic diagram of the top half of a clutch device 1 in an auxiliary drive train of a motor vehicle is shown.

[0046] The clutch device comprises a drive shaft 2 driven by a not shown internal combustion engine, which is rotatable relative to an electromagnetic device 3 . The stationary electromagnetic unit 3 including the energizable coil 4 is supported in the radial and axial direction on the drive shaft 2 via a rolling bearing 5 designed here as a ball bearing.

[0047] In the region of the free end 6 of the drive shaft 2 , an armature (armature disc) designed as an armature disc is secured to the drive shaft in a rotationally fixed manner, ie via a disc-shaped return spring 8 . The armature 7 is adjustable via the energization of the coil 4 relative to the output 9 , which is mounted rotatably relative to the drive shaft 2 and supported on the drive shaft 2 via a roller bearing 10 designed as a double ball bearing. For example, fan blades can be atta...

Abstract

The coupling arrangement (1) has a drive shaft (2) that includes friction surface (20) relative to an output unit (9). The output unit is moved by energizing an energisable winding (4). A movable armature (7) is formed with friction surface (19) comprising friction disc coupling agents. The fluid (16) such as silicon oil is filled in shear gap (21) comprising fluid friction clutch coupler (14). The friction disc coupling agents are combined with fluid friction clutch coupler. The shear gap is limited by the movable armature.

Description

technical field [0001] The invention relates to a clutch device according to the preamble of claim 1 for transmitting a drive torque to an auxiliary device of a motor vehicle, in particular to a fan wheel. Background technique [0002] In principle, one-speed or multi-speed friction disc clutches are known for driving auxiliary equipment, for example fan wheels. Such friction disc clutches, which are designed, for example, as electromagnetically actuated clutches, are described, for example, in EP 0 317 703 A2, DE 32 03 1 43 C2 or DE 42 07 10 C2. With regard to the basic structure, mode of operation and field of use of such friction disc clutches, reference can be made to these publications. In the prior art, pneumatically or hydraulically actuated friction disk clutches can be used instead of such clutches with electromagnetic switching mechanisms. [0003] In order to generate a rotational speed-dependent traction torque without variable rotational speed regulation, it i...
