Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The disclosure is explained below in more detail with reference to an exemplary embodiment. The Figures schematically show:

[0061] FIG. 1 shows a perspective view of an exemplary embodiment of a door drive with a deactivated blocking device; and

[0062] FIG. 2 shows a view as in FIG. 1, but with an activated blocking device.

DETAILED DESCRIPTION OF THE DRAWINGS

[0063] As FIG. 1 shows, the exemplary embodiment of the drive unit 1 for the door of a vehicle shown in the drawings comprises a drive unit 2 comprising a rotation motor 3, a first torque transmitting device 4 for transmitting a first torque and a second torque transmitting device 5 for transmitting a second torque.

[0064] The door drive comprises a blocking device 6 for blocking the first torque transmitting device 4. The blocking device 6 can be activated and deactivated. For this purpose, the door drive 1 comprises an actuating member 7. The blocking device 6 is a drive-internal blocking device.

[0065] In the depicted exemplary embodiment, the first and second torque transmitting device 4, 5 are each formed by a toothed belt pulley. An actuating lever as a second torque transmitting device 5 would also be possible, for example.

[0066] A drive power of the electric rotation motor 3 can be transmitted successively via the first torque transmitting device 4 and the second torque transmitting device 5. The transmission of the drive power of the rotation motor via the respectively desired torque transmitting device 4, 5 can be achieved by blocking the other torque transmitting device 4, 5.

[0067] The drive unit 1 comprises a gearing unit 11 with two gearings, i.e. an epicyclic gearing 15 and a bevel gearing 24, which are combined with a rotation motor 3 to form a gear motor. Depending on the assembly situation, the bevel gearing may also be omitted. The common gear case 13 of the two gearings can be firmly fixed to a vehicle. The gearing unit 11 has a drive side, a first output side 8 and a second output side 9. The first torque transmitting device 4 is arranged on the first output side 8, and the second torque transmitting device 5 is arranged on the second output side 9. An output shaft 12 is arranged on the first output side 8, e.g. operatively connected to the planet carrier of the epicyclic gearing, and the ring gear 16 of the epicyclic gearing rotatably mounted in the gear case 13 is arranged on the second output side 9.

[0068] The actuating member 7 is also arranged on the second output side 9 and operatively connected in this manner to the second torque transmitting device 5.

[0069] The motor housing 14 of the rotation motor 3 is not firmly clamped but, together with the ring gear 16 and the second torque transmitting device 5, can be rotated back and forth by about 60 degrees.

[0070] As FIGS. 1 and 2 show, the blocking device 6, which can be mechanically activated and deactivated, has a rod-shaped blocking member 10 which, guided by a linear guide 17 arranged on the gear case 13, can be translationally displaced between a releasing position P1 and a blocking position P2 by means of the actuating member 7. In the blocking position P2 shown in FIG. 2, the blocking device 6 blocks the rotary movement of the first torque transmitting device 4, whereby the entire drive power of the rotation motor 3 is transmitted via the second torque transmitting device 5.

[0071] The blocking member 10 has a blocking head 18 for positively blocking the first torque transmitting device 4.

[0072] The blocking device 6 comprises a spring 22, which acts on the blocking member 10 and whose force acts against a displacement of the blocking member 10 from the releasing position P1 into the blocking position P2.

[0073] The blocking member 10 has a contact region 19, and the actuating member 7 has an actuating region 20, which has a control contour with a ramp portion 21 and a plateau portion 23. The displacement of the blocking member 10 from the releasing position P1 into the blocking position P2 can be attained by a sliding contact of the contact region 19 with the ramp portion 21 during the rotation of the actuating member 7.

[0074] As FIG. 2 shows, a retention of the blocking member 10 against the force of the spring 22 and in the blocking position P2 can additionally be achieved by a contact of the contact region 19 with the plateau portion 23.
