Abstract: The invention relates to a vibration exciter, in particular for a construction machine, having at least one rotatably supported unbalanced unit with at least one unbalanced element, a rotary drive, a gear arrangement with at least one gear wheel, wherein a rotation generated by the rotary drive can be transmitted by the gear arrangement to the at least one unbalanced unit, and a housing, in which the gear arrangement is accommodated. In accordance with the invention an energy-saving and low-maintenance arrangement is achieved in that by the gear arrangement an output shaft can be driven that extends out of the housing and in that the at least one unbalanced element is fixed outside of the housing on the output shaft.

Abstract: An electric drive unit for a vehicle is disclosed which has two electric machines axially aligned and connected with each other in mirror image. Each electric machine has a casing (3), a rotor (2) having a wheel body (16), an inner annular stator (4) including stator windings (5), having an axial, substantially cylindrical recess (11). The stator is attached to the casing (3), a rotor shaft (7) is attached to the wheel body (16) and extends into the substantially cylindrical axial recess (11) of the stator (4). There are first mounting means (20) rotatably mounted within the housing and relative thereto for mounting the rotor shaft (7); and an output coupling means (8, 9, 19, 25, 26) having a connecting flange (25, 26) for detachably connecting an output shaft thereto, the output coupling means (8, 9, 19, 25, 2 86) being disposed substantially within the axial cylindrical recess (11).

Abstract: A mounting sleeve extends from a vehicle body or other housing and contains on its body/housing side a planetary gearing whereby, in particular, the sleeve is provided with an internal ring gear for planetary gearing; the sun gear is carried by an input shaft, and the planet gear carrier is integral with a shaft which is keyed to a hub; the hub is journaled by two roller bearings in the mounting sleeve both being on the same side, as far as the planetary gearing is concerned. The roller bearing elements are of a frustoconical configuration, and their axes are particularly oriented to prevent the reaction of radial and axial forces into the gearing.
