Abstract: A web unit for planet gear sets for the mounting of planet gears including a first web element and a second web element, which are tightly connected and can be tensioned in axial direction by transmission or connecting elements progressing in axial direction and describing a theoretical connecting axis. Each transmission or connecting element has regions of differing radial dimensions, the front faces of the regions, thus formed and facing the individual web elements, form a first and a second contact surface, resting either directly or through an intermediate element against the contact surfaces in contact regions, formed by the front faces of the web elements facing each other. At least one element forming a contact surface of a contact region includes a profile. The profile is characterized in the radially external region by at least one region of greater axial extension in the direction of the theoretical connecting axis.

Abstract: A process for the assembling of a gear component having a gear housing which has a substantially cylindrical interior space for the reception of individual gear elements; at least two bar-form guide elements which, as viewed in an axial direction, extend over and are adjacent to at least a part of the axial extent of the cylindrical interior space and on which there are mounted a gear element. The bar-form guide elements are adjacent to the cylindrical interior space and outside of the zone having the greatest dimensions of the cylindrical interior space in the height direction. The individual gear elements are threaded successively from one housing end onto the guide elements and are slid into their installation position in the gear housing.

Abstract: A gear constructional unit with a gear housing is provided. In order to make the effective diameter of the inner gear elements greater, as well as to ensure a simple assembly and exchangeability of the individual gear elements, for example coupling arrangements and planetary wheel sets, there are provided at least two bar-form guide elements, which extend, as viewed in an axial direction, over at least a part of the axial extent of the cylindrical inner space, on which a large number of gear elements are mounted in fixed position with respect to the housing. The bar-form guide elements are located adjacent to the cylindrical inner space, outside of a zone having the greatest dimension of the cylindrical inner space relative to the gear housing dimension, and are arranged in recesses in the gear housing which are connected with the inner space.

The gear housing has an essentially cylindrical interior space for the reception of individual gear elements. The gear unit includes a device for the at least indirect resetting of actuating elements of non positive coupling and/or braking arrangements with at least two friction surface-carrying elements, the friction surfaces of which are connectable with one another over a further friction surface-carrying intermediate element.

Abstract: The invention relates to a hydrodynamic mechanical compound transmission comprising a transmission input shaft (E), a transmission output shaft (A), a hydrodynamic transmission part (2) and a mechanical transmission part (4). Said mechanical transmission part (4) comprises at least one speed/torque conversion device (5). The output of the mechanical speed/torque converter (5) is at least indirectly drive-connected to the transmission output shaft (1). According to the invention, the hydrodynamic retarder (25) which comprises a stator (26) and a rotor blade wheel (27) is spatially integrated in the transmission housing (11). In addition, the rotor blade wheel (27) of the hydrodynamic retarder (25) is at least indirectly coupled to the output shaft (A) of the mechanical speed/torque converter (5). The hydrodynamic retarder (25) functions as a secondary retarder, however, it is spatially arranged in the transmission before the downstream stage (6).

Abstract: With a differential gearing having a spur gear construction, the compensating gears (31a, 31b) are installed in meshing pairs and are tightly enclosed by a housing (14) so that with meshing spur gears (22, 23) they can act as toothed pumps with pressure zones, with a locking moment being produced between the two driven shafts (2,3). A substantial increase in the locking moment is achieved in that the compensating gears constructed as pinions are disposed in a determined sequence on the circumference of the spur gears and also comprise along their face width partitions (32) which prevent a reduction in pressure along the toothing. As a result with an equal number of pinion pairs there is produced a number of pressure zones which is more than double and consequently there is an increase in the locking moment developed.

Abstract: A differential gearing, in which the torque introduced via an input shaft is distributed equally to two driven shafts, is constructed as a spur gear differential and has a pinion arrangement as the locking mechanism in which the pinions and spur gears work as geared pumps. The pump moment is directly the locking moment, with the hydrostatic pressure developed being reduced by precisely dimensioned clearances without any further control devices being required. A special arrangement of the pinions in a housing guarantees an equal locking moment in both directions of rotation.
