摘要： The invention relates to a rotary slide valve (5, 6) with a spring loaded (31) centring system (25). The centring system is to be fitted inside the valve housing (1) without the need for additional structural space in the radial direction. In addition, the return pressure is to be reduced. According to the invention, the spring (31) presses on a reaction piston (32), a centring component (24) of which acts on rolling bodies (30) in the centring system (25). Between a cover (35) and the reacting piston (32) there is a reaction chamber (37) to which a variable pressure can be applied. At high travelling speeds, a pressure assisting the spring (31) in the reaction chamber (37) acts on a front face (41) of the reaction piston (32). Because the force of reaction pressure supplements that of the spring (31), a smaller spring can be used and space is saved.

摘要： The invention concerns a power-assisted hydraulic steering system with a rotary-spool valve (5, 6) and in which the relationship between the hand steering force and the hydraulic assistance can be characterized by the valve characteristic curve. Generally, a tight tolerance interval is required for this characteristic curve. The aim of the invention is to provide a device for the adjustment of the valve characteristic curve. In addition to the slot zones (Z, Z1) for normal control of the servo motor (27), the invention calls for additional zones (S, S1) for redistributing the hydraulic-fluid flow. Fitted in the return channel of the additional slot zones (S, S1) is an adjustable shutter (32). By modifying the hydraulic-fluid flow emerging through these slot zones (S, S1), the valve characteristic curve can be corrected.

摘要： A container for a flow medium made of plastic material comprises a container pot (1) which can be closed by a lid (2). The container pot (1) and the lid (2) are adapted to each other, as far as their position is concerned, on a mold parting line (7), and fixed by a centering device (8). Both the container pot (1) and the lid (2) comprise a surface (10, 11), which are adjacent to each other. A welded plate (12), which also consists of plastic, engages with the adjacent surfaces of the container pot (1) and the lid (2), said plate being adjusted to the neighboring surfaces (10, 11). The container pot (1) and the lid (2) are hermetically interconnected by the welded plate (12) using a friction welding process. This configuration makes it possible to prevent plastic particles arising from lateral wastes during friction welding from entering the flow medium container.

摘要： A continuously variable transmission control method designed to determine an operating point from the number of revolutions of the primary disk (12) and the number of revolutions of the secondary disk (13). The operating point is assigned to a first characteristic field which has ranges of unauthorized ratios and a range of authorized ratio. If an error occurs, the pressure level in the adjustment area of the secondary disk (pSEK) is increased in an initial step. If the error continues an emergency drive program is activated in a second step.

摘要： In a rack-and-pinion assisted steering system with an elastic connection housing, for example made of plastics, arranged between the pinion housing (6) and the cylinder housing, the bearing points of the rack (1) and pinion (2) are not fixed in a housing. The pinion axis (A) is aligned with the pinion housing by using the existent contact line (B) between rack and pinion teeth. According to the invention, the rack teeth are pressed without play between the pinion teeth by means of an additional pressure member (7) in the lid (5) of the compression piece (3), aligning thereby the pinion axis (A) with the pinion housing (6). After the rack-and-pinion assisted steering system is mounted in the vehicle, the pressure member (7) is removed and the effect of the spring-mounted compression piece (3) is re-established. The aligned pinion axis (A) ensures a good rolling between pinion and rack teeth.

摘要： The invention relates to a drive control for motor vehicles or utility vehicles wherein sensors enable the speed of the wheels and the steering angle to be measured. Driving axle slip is determined by comparing the average peripheral wheel speeds of the driven and non driven axles and by taking steering geometry into account. Driving force and finally chassis efficiency are determined by the slip with the assistance of standard characteristic curves. All-wheel drive efficiency is compared with rear wheel drive efficiency. The drive with the higher degree of efficiency is engaged.

摘要： The invention relates to an accumulator (1) for supplying oil to servo devices. In hydraulic facilities operating with an accumulator (1), the pump often causes disturbing noise resulting from oil pressure pulsation. In order to reduce said pulsation, the inventive accumulator has two connecting openings, one for oil intake and the other for oil discharge. Upon oil inflow there occurs a substantial cross-sectional change resulting in damped pulsation. Besides, the accumulator (1) acts as an extensible hose, so that the damping effect is increased.

摘要： The invention concerns a toroidal drive which can be operated in two performance ranges. The input shaft (2) of the gear is connected to an intermediate shaft (5) via a first transformation stage (wheels (3) and (4)). From the intermediate shaft a continuously variable transmission (CVT) is driven via a further transformation stage (wheels (6) and (7), drive chain (9)). A further transformation stage (21) is connected downstream of the CVT. The input power is either fed directly to a summarizing gear set (24) or - with the power being branched - is introduced into the summarizing gear set (24) via a further transformation stage (wheels (29) and (30)). The total of three transformation stages present enable the ratios between the speeds of rotation within the CVT to be optimized. Preferably the drive is suitable for use in a vehicle in whose drive train the engine, transmission and output are disposed in a line.
