If the fastener For example, made of plastic, the connection between the rod-shaped offset compensation element and, for example, the Drive levers are made using a plastic band or plastic web. Since that Offset compensation element in this embodiment torsionally stiff and extremely flexible with the actuator or a component of the Actuator or the pivot shaft is connected, the assembly simplified since only one connection has to be installed. At this The connection is then preferably the one above described connection between a recording and an example head-like extension of the offset compensation element so that the Offset compensation element only has to be inserted into the receptacle.
- rod-shaped offset compensation element itself by an essentially bendable perpendicular to its longitudinal axis and in Essentially torsionally rigid.
- the through manufacturing tolerances can be caused by a slight bending of the Offset compensation element are compensated.
- Even with such a Offset compensation element is the assembly versus the assembly of a Coupling considerably simplified. Furthermore, the required space is required lower.
- the offset compensation element itself is bendable about the bending axis it is possible to connect the connectors or connecting elements between the Switching shaft and the offset compensation element or between the Actuator and the offset compensation element parallel to each other to be moved. As a result, the tiltability of the Connectors in a receptacle of the shaft or the actuator is not required.
- the connectors can thus be made simpler his. For example, a simple snap connection or the like. sufficient.
- a flap arrangement (FIG. 1) has a flap 10, for example one Shaft, swirl or tumble flap.
- the flap 10 is with a switching shaft 12 connected.
- the control shaft 12 is as Approach connected in one piece to the flap 10, with several flaps 10 are connected to one another via the common selector shaft 12.
- the Switch shaft 12 is mounted in bearing parts 14 and in a housing 16 arranged. With the selector shaft 12 is the rod-shaped invention Offset compensation element 18 connected.
- the offset compensation element 18 is also provided with one in the housing 16 mounted drive lever 20 connected, part of an actuator is.
- the actuating device further comprises an electric servomotor or the like. Between a cylindrical projection 22 of the drive lever 20 and the Housing 16 is provided with a circumferential seal 24.
- the rod-shaped offset compensation element 18 has in the illustrated Embodiment a head or an extension 26 at each end.
- the head 26 connected to the shaft 12 is within one shown in FIG Embodiment arranged as a recess 28 arranged.
- the head 26 is designed as a hexagon in the illustrated embodiment and thus has six rotation transmission surfaces 30 (FIG. 2).
- the rotational or pivoting movement of the offset compensation element 18 on the Switching shaft 12 also has a regular receptacle 28 hexagonal cross section on (Fig. 2).
- the selector shaft 12 has slots 34, so that the Switch shaft 12 in this area by pressing the head 26 elastic expanded and with the head 26 fully inserted into the starting position got back.
- the two heads 26 of the offset compensation element 18 in the Receptacle 28 of the shaft 12 and in a receptacle 40 of the drive lever 20 each pivotable in the direction of an arrow 42 or 44.
- the Rotation transmission surfaces 30 in the longitudinal direction of the Offset compensation elements 18 curved Fig. 1).
- the recording 28 in the Shaft 12 is complementary to the six rotation transmission surfaces curved surfaces.
- the offset compensation element 18 is thus one extending perpendicular to the longitudinal axis 46 of the offset compensation element 18 Axes 48 or 50 can be swiveled.
- the receptacle 40 in the drive lever 20 and the head 26 of the Offset compensation elements, which are held in the receptacle 40 corresponding to the opposite head 26, which on the receptacle 40 of the Shaft is arranged, trained.
- the receptacle 40 is also to allow elastic expansion slotted.
- the approach 22 of the Drive lever 20 for mounting the drive lever 20 in the housing 16th serves as a hollow cylinder, so that in particular more than half the length of the offset compensation element within the drive lever 20 is arranged.
- the second preferred embodiment differs from that first embodiment (FIGS. 1 and 2) only through the connection between the drive lever 20 and the offset compensation element 18. Identical and similar components of the embodiment are thus included identified by the same reference numerals.
- the offset compensation element 18 is in the illustrated embodiment directly connected to the drive lever 20.
- a connecting element 52 which may be film-like, intended.
- the connecting element is torsionally rigid, so that turning or pivoting the drive lever 20 is transmitted to the shaft 12.
- the Connecting element 52 which is preferably made of plastic however, bendable so that pivoting in the direction of an arrow 54 is possible is. This can cause an offset of the shaft 12 and the drive lever 20 be balanced. It goes without saying that the offset is also compensated for possible perpendicular to the drawing plane.
- the connecting element its thickness depends on the material used in order to have a corresponding flexibility enable, for example, can be slotted or as a continuous circumferential ring be formed. To find a suitable bendability enable, the offset compensation element 18 is in the range of Connecting element 52 is hollow.
- the offset is not compensated by an in rod-shaped offset compensation element 18 arranged at an angle, but through a rod-shaped bendable but torsionally rigid Offset compensation element 56.
- the offset compensation element 56 is of this type formed that the two connecting pieces 58, 60, which are to be connected to an actuating device 62 and the shaft 12 serve, parallel to each other are displaceable, an intermediate piece 64 of the offset compensation element 56 is bent.
- that would be shown in the Embodiment head-shaped connector 60 in Fig. 4 parallel upwards pushed while the position of the connector 58 remains unchanged.
- Intermediate piece 64 bending areas 66 are examples of the offset compensation element 56.
- the intermediate piece 64 is partially meandering. It is therefore possible to use the offset compensation element 56, the control shaft 12 with a connector the actuating device 62 or an intermediate drive lever or the like. to connect, although the axis of rotation 36 of the shaft 12 is offset from the Rotation axis 38 of the drive lever or the actuating device 62 is arranged.
- the offset compensation element 56 is thus perpendicular to it Longitudinal axis 68 extending bending axis bendable.
- the connector 60 corresponds in design to the head 26 of the Offset compensation elements 18 (Fig. 1). This is an additional Swiveling the offset compensation element 56 with respect to the shaft 12 and thus a further simplified compensation of the offset is possible.
- the connector 58 is a conventional snap or snap connection designed, but can also be designed according to the head 60 his.
