Definitions
- Drive unit for an actuator, as well as actuator with a drive unit and a gear unit
- Rotary movement is displaceable, and connected to a first pinion first worm and a second pinion connected to a second worm wheel, which contact the worm shaft such that the first worm wheel and the first pinion about a common first axis of rotation and the second worm wheel and the second pinion are rotatable about a common second axis of rotation.
- the transmission device has an adjustable piston, which is adjustable along an adjustment axis by means of the first pinion rotated about the first axis of rotation and the second pinion rotated about the second axis of rotation.
- the invention relates to a
- Counter element is part of a transmission axis of the gear unit. This has the advantage that a mechanical interaction between the transmission axis and the drive element is present, which is suitable to stabilize the transmission axis. If the transmission axis were mounted on both sides in a thin gear housing, the bearing forces transmitted to the gear housing may be too large and cause the gear housing to deform elastically under load. This could have the disadvantage that the transmission axle tilts under load. Likewise, a meshing engagement of a gear present in the transmission with a drive gear can increasingly deviate from the desired state. This can lead to higher noise and higher tooth stress.
- the housing of the drive unit can be made more stable than the housing of the gear unit, whereby the housing of the drive unit is better suited for supporting the transmission axis.
- the housing of the drive unit can support stronger forces. A tilting of the transmission axis can be effectively prevented, which improves the functionality of the transmission unit.
- the drive unit may be an electric motor, in particular a
- Electric motor with an attached control unit for example, a so-called power pack.
- the transmission unit may be part of an actuator, which is a brake booster, which is to be driven with the drive unit.
- Alignment element and counter element can be present as a plug / socket, or socket / plug.

- Drive axis are aligned parallel to each other in their respective longitudinal direction and offset from one another, wherein in particular the alignment in the longitudinal direction of the drive axle and the alignment element corresponds to a mounting direction of the drive unit with respect to the gear unit.
- This has the advantage that when mounting the units alignment element and counter element can be easily brought into engagement. Due to the predetermined offset of alignment element and drive axle and a distance to be achieved between the drive shaft and the transmission axis can be easily achieved during assembly, which ensures better performance of the drive and transmission.
- the alignment element is part of a housing of the drive unit. As a result, a good support of forces of the transmission axis can be achieved.
- a simple production of the drive unit with the alignment element is possible, for example in one piece as a pressed part or as a stamped part or as a cast part.
- the alignment element is attached directly or indirectly to a housing of the drive unit.
- the alignment element is present as a separate component which is directly or indirectly connected to the housing of the drive unit.
- the actuator according to the invention has such a drive unit and a transmission unit.
- the gear unit has the described counter element, which can be brought into engagement with the alignment element of the drive unit.
- the drive unit is mechanically connected to the gear unit in such a way that the counterpart element of the gear unit engages with the alignment element of the drive unit.
- the counter element is part of a transmission axis of the transmission unit.
- the brake booster with such a built drive unit has the advantage that an optimal alignment of the transmission axis of the
- Transmission unit is achieved by this is supported on the drive unit. It is also advantageous that a degree of freedom is determined by engagement of alignment element and counter element for a correct orientation of the drive unit to the gear unit. This allows easier installation.

- a region between the drive unit and the gear unit, in which the counter element is brought into engagement with the alignment element sealed media-tight by means of a sealing element. This prevents water or dirt from getting inside the gearbox.
- the sealing element is arranged around the counter element. This allows a space-saving installation of a seal.
- Alignment is arranged around when the alignment element is engaged with the counter element.
- An encompassing seal that engages both parts can make an additional seal unnecessary.
- the sealing element can be arranged between a housing wall of the drive unit and a housing wall of the gear unit. This arrangement allows easy fixation of the seal, since drive and gear unit are fixed to each other during assembly anyway.
- the counter element, and the sealing element is covered by a cap.
- a cap it is sufficient to provide a single seal and no further separate seal.
- Counter-element is accompanied by a corresponding cover of the corresponding alignment element.
- a cover may be provided regardless of which element of alignment element and counter element as a pin and which element is provided as a trough or hole. The cap should then be adjusted according to the orientation.
