    Abstract: A range gearbox with planetary gear (1) for motor vehicles intended to be connected to the output side of a basic gearbox. The ring gear (18) of the planetary gear is axially displaceable. The ring gear (18) can engage coupling rings (10, 16) alternatively. A synchronizing member or member (15) is intended to synchronize the rotational speed difference between the ring gear (18) and one or other coupling ring (10, 16). The synchronizing means (15) and the coupling ring (16) are arranged coaxially outside the ring gear (18). A second member or engagement member (25) for engaging the coupling ring (16) and a third member or engagement member (25, 25b) for driving said synchronizing member (15) are arranged on the external side, as seen radially, of the ring gear (18). The coupling ring (16) is arranged between the synchronizing member (15) and the first member (27).

    Abstract: A mechanical gear transmission between an engine and a load includes shiftable speed change gearing. Brakes or clutches are provided for shift synchronization when changing to different speeds. Positioned between the engine and the gearing is a main synchronization element such as a clutch. The primary segment of the main synchronization element is driven by the engine output shaft while the secondary segment drives the input shaft of the speed change gearing. During a gear shift under load, the main synchronization element is maintained in a slip mode for a longer duration than the gearing synchronization element and provides the major portion of the total synchronization work. In alternate embodiments, the main synchronization element is combined with a planetary gearing for speed reduction on a pair of planetary gearings for reversing direction. A further embodiment incorporates a microprocessor controller and sensors for monitoring various engine and transmission functions. The microprocessor controller actuates the main and the gearing synchronization elements and may control the engine during a gear change.

    Abstract: An improved change speed planetary transmission (100) of the type utilizing planetary gearing (102) to drivingly connect an input shaft (12) to an output shaft (14) is provided. The planetary gearing includes a sun gear (104) fixed for rotation with the input shaft, planet gears (110) constantly meshed with the sun gear and rotationally supported on planet gear shafts (114) carried by a planet carrier (116) fixed for rotation with the output shaft and a ring gear (120) constantly meshed with the planet gears. The ring gear is selectively axially moveable relative to the transmission housing (18) and the sun gear and planet gears to a first position for positive engagement with a clutch member (134) fixed for rotation with the housing to provide an indirect ratio mode of operation and to a second axial position for positive engagement with a clutch member (126) fixed to the sun gear to provide a direct ratio mode of operation. In the direct ratio mode of operation of the transmission, the forces (2F.sub.1) tending to cause brinelling of the planet gear support surfaces of the planet gear shafts are considerably reduced relative to corresponding forces (2F.sub.2) in the prior art designs (10).
