Abstract: The invention concerns a motor-vehicle drive train (1) with a drive motor (2), a gearbox (3) and an axle (6). The gearbox output shaft (7) is connected by means of a joint (8) to a joint shaft (9). A second joint (10) transmits the drive from the joint shaft (9) to the input shaft (11) of a differential gearbox (4). In order to allow the joint shaft (9) to have a W-configuration, the drive motor (2) and gearbox (3) are mounted so that they can pivot about the axle (6). Any divergence from the longitudinal axis of the drive line (1) immediately produces a large angle of inflection in the joints. Torque irregularities in the drive line are therefore avoided. In addition to reducing the load on the joints, the generation of disagreeable noise is avoided. The invention is particularly suitable for use in utility vehicles such as those used in the construction industry and in agriculture.

Abstract: The invention relates to a multi-ratio reversing power shiftable gear (1). In order to obtain a multi-ratio reversing gear (1) of compact construction, especially one which is axially short, there is a single clutch (19, 20, 21, 29, 31 and 41), an idler gear and up to two fixed gears on each layshaft. The pinions of the reversing gear form a set of drive wheels (12), a set of distribution wheels (35) and a driven gear system (34). With the same structure in principle it is possible to provide different gear variants with differing numbers of gears and axial differences. The reversing gear (1) is especially suitable for use in building machinery.

Abstract: A power shift gear comprises a pump (1) for the lubricant and hydraulic fluid. The lubricating and hydraulic oil delivered by the pump is used to actuate clutches, to fill a hydrodynamic unit and to supply the gear lubricating device (5). The pressure in the individual supply lines (31, 41, 51, 52) is adapted to the corresponding use by means of pressure-control valves, pressure-relief valves (12, 43) and safety valves (53). The gear lubricating device is supplied through two lubricant lines (51, 52). The first line (51) conveys the hydraulic oil which has flowed through the hydrodynamic torque transducer (4) to the gear lubricating device (5), and a second lubricant line (52) takes lubricating oil from the supply circuit upstream of the hydrodynamic unit (4) and conveys it to the gear lubricating device. Both lubricant lines (51, 52) meet to form a single line (54) upstream of the gear lubricating device (5).

Abstract: The invention relates to a multispeed powershift reversing gear (1). To achieve a compact design, especially an axially short construction, in a multispeed reversing gear (1), each countershaft has mounted on it a single clutch (19, 20, 21, 29, 31 and 41), an idler gear and up to two fixed gears (37 and 38). Gearwheels of the reversing gear form a drive gear set (12), a distributor gear set (35) and a driven gear chain (34). Besides the ratio of the drive gear set (12), a different ratio related to another clutch is established through an independent drive chain consisting of a fixed gear (9) and an idler gear (15) with a clutch (21). With the same essential design, different gear configurations can be constituted with different numbers of gears and different center distances. The reversing gear (1) is especially designed for use in construction machinery.

Abstract: A power-shiftable, multiple gear reversing gear box (1) of the layshaft type is disclosed, such as those used in particular in construction machinery. In order to attain a high number of light parts and to keep low the noise level, a single clutch (21 to 24) is arranged on each layshaft (17 to 20). The idlers (25 to 28) associated to the clutches (21 to 24) form a driving gear chain (29). The disclosed solution is characterised in particular by a small axial length of the layshafts, so that helical gears with a wide helix angle may be used.

Abstract: L'ensemble de roue est caractérisé par une distance extrêmement courte entre le flasque de roue (14) et la suspension de l'essieu (liaison (7)) et par sa conception très compacte. En effet, le cadre (8) est maintenu près de la roue (21) sur un élément de liaison (7) qui peut servir directement comme plaque de support de frein (6); le tambour de frein (13), qui est en saillie axiale par rapport au flasque de roue (14), et passe sur un moyeu de zone commun (16), peut être maintenu à une distance extrêmement courte de la roue grâce à des paliers à rouleaux coniques (15) situés le plus près possible l'un de l'autre.

Abstract: The aim of the invention is to make it possible to accurately control a clutch (2) which is disposed inside a hydrodynamic torque converter (1). The aim is achieved by the fact that a pressure acting on the first face of a piston (4) is transferred to a control unit which adjusts a pressure acting on the second face of the piston (5) according to the pressure acting on the first face thereof. Said invention makes it possible to accurately adjust a piston force applied to the clutch (2) even at a fluctuating pressure inside the inventive hydrodynamic torque converter.
