摘要： The invention relates to a drive unit, in particular for loading equipment in an airplane, with a drive element (8) contained in a housing (7). According to the invention the drive unit is connected to the housing (7) by linear guides (25, 26) which are guides for vertical movement. The transmission includes a planetary gear in which the planet gear carrier is made in the form of a swivelling planet wheel rocker (16). Supporting elements (23, 24) are provided on the planet wheel rocker (16) and these engage respective stops (34, 35). The supporting elements provide an opposing moment on the planet wheel rocker (16) as a reaction to a braking moment exerted on a conveying wheel (9). This causes an upward contact pressure (arrow 43) to be exerted on the drive element (8) and thereby on the conveying wheel (9). In this manner, the contact pressure (arrow 43) is optimally adjusted to a load placed on the conveying wheel, so that wear and maintenance are reduced and overloading of the equipment is avoided (FIG. 4).
