摘要： The invention relates to a drive device (10) for a high-pressure cleaning unit having a motor (12), the motor shaft (14) of which is coupled to a swash plate (18) via a planetary gear set (16), wherein the planetary gear set has a sun gear (26) connected in a rotationally fixed manner to the motor shaft, which sun gear meshes with planetary gears (28, 29) which are mounted so as to be able to rotate on a planetary bearing (35) and engage with an internally toothed internal gear (31) and with their end side facing away from the planetary bearing lie against a support element (60) so as to able to slide. In order to construct the drive device in such a manner that it has an increased service life, it is proposed according to the invention that the support element takes up a wear-inhibiting bearing region for the planetary gears. Alternatively, or supplementary thereto, it is proposed that the swash plate is supported by a bearing plate (40) which dips into a receptacle (42, 74) which supports the bearing plate in an axial and radial direction.
