- the clutch 6 is actuated by means of a controllable actuator 45, which acts on the coupling element 44 in order to transfer this selectively into the closed position or the open position.
- the actuator 45 is designed as an electromagnetic actuator, that is, the axial displacement of the coupling element 44 takes place by means of magnetic forces. It is understood, however, that other types of actuators can also be used, for example electromotive, hydraulic or pneumatic actuators.
- the actuator 45 has an actuator housing 46, which is connected via a flange 47 with the clutch housing 3. Furthermore, the actuator 45 has an axially movable piston rod 48, the end remote from the actuator is received in a bore 49 of the clutch housing 3 axially movable.
- a shift fork 50 is fixed, which engages in an annular groove 52 of the coupling member 44 in order to transmit an axial movement of the piston rod 48 to the coupling element 44.
- An advantage of the clutch module 2 is that it can be used for many applications or in various installation situations within the drive train of a motor vehicle.
- the clutch module 2 can be connected to a transfer case or a differential gear, in terms of the power path in front of or behind the transmission.
- FIG. 5 shows a drive arrangement 53 according to the invention with a differential gear 54 and a clutch module 2 according to the invention according to FIGS. 1 to 4.
- the differential gear 54 comprises a stationary housing 55, in which a differential cage 56 is rotatably supported by means of two bearings 57, 58 about an axis of rotation A56.
- a ring gear 59 is provided, which is firmly connected to the differential carrier, for example by means of a welded connection or screw connections.
- a plurality of differential wheels 60 are rotatably mounted on a pin 62 about a pin axis A62. The two differential wheels 60 revolve together with the differential cage 56 and are respectively in meshing engagement with a first and a second driven gear 63, 64 which are coaxial with the axis of rotation A56.
- the two output gears 63, 64 which may also be referred to as side-shaft gears 63, 64, each have a spline 65 (splines) into which a corresponding counter-toothing 66 of a drive shaft 4 can engage for torque transmission.
- the two driven wheels 63, 64 are supported axially via intermediate sliding disks 66, 67 with respect to the differential carrier 56.
- the fixed gear housing 55 is fixedly connected to the clutch housing 3 via a connection assembly 68.
- the connecting arrangement 68 is designed in the present case in the form of a flange connection, and comprises the connecting elements 34 on the coupling housing 3, which are designed as flange, corresponding flange portions 69 on the gear housing 55 and the two flange portions 34, 69 interconnecting bolts 70.
- Between the gear housing 55 and the coupling housing 3 is also a centering 72nd provided, with which the two housings 3, 55 are centered relative to each other.
- the centering arrangement 72 comprises the centering surface 10 of the coupling housing 3 and a corresponding centering surface 73 on the transmission housing 55, so that the two housings 3, 55 are centered relative to one another.
- the centering surfaces 10, 73 are formed on corresponding sleeve-shaped centering portions of the housing 3, 55 and designed in particular cylindrical.
- the centering arrangement 72 is arranged in particular in an axial covering area with the shaft bearing 38, so that an exact coaxial alignment of the drive shaft 4 is achieved.
- a sealing ring 74 is disposed in an annular groove between the centering surfaces 10, 73.
- the coupling module 2 according to FIG. 5 largely corresponds to that according to FIGS. 1 to 4, so that reference is made to the above description to avoid repetition.
- the same or corresponding components are provided with the same reference numerals as in the embodiment according to FIGS. 1 to 4.
- a first difference is that, in the embodiment according to FIG. 5, the connecting elements 34 for connecting to the gear housing 55 are designed separately from the connecting means for connecting the two coupling housing parts 32, 33. Another difference is that the piston rod 48 is free of support at its end remote from the actuator 45. Furthermore, an annular groove for the sealing ring 74 is provided in the centering surface 10 of the coupling housing 3.
- the coupling module 2 shown in FIG. 5 at least substantially corresponds to the coupling module 2 shown in FIGS. 1 to 4, so that reference is made to the above description.
- a coupling module 2 can be easily connected as a separate, preassembled structural unit with a transmission. At the same time, a defined interface with centering and connecting elements enables easy assembly. In addition, the coupling module 2 has a compact size, so that it is particularly suitable for use in an axle shaft or side shaft of a drive axle. LIST OF REFERENCE NUMBERS
