摘要： Multiple axle vehicules with independent wheel drives, provided to improve the ground clearance also with transmission lines (6, 7) in two portions and arranged close to the wheels, wherein distributor gears (4) drive the wheels through transmission shafts (20). In order to obtain drive shafts which, despite short intervals of the case between the distributor gear and the hub, are not short to the point of strongly limiting the orientation angle of the axle (31) or to affect the joints and also to allow longer dumping strokes of the wheels, the joints (19) and/or the hub gear are integrated in the case (25) of the distributor (4) so that the joint middle is arranged directly at the intersection point, and even behind said point, between the drive shaft (20) and the drive line (6, 7) and under the output bearing. Thus, a specially large diameter is obtained for a short length.

摘要： Control device for a clutch (1) with torque converter arranged as a common construction with a synchronized gear transmission, the clutch being closed by means of a control of the gear shift unit by two pressure chambers (4, 6) arranged radially in parallel, as a function of the rotation speed as well as of the operating conditions, with a soft coupling and, after a fast emptying, opened by spring effect. The radially outer pressure chamber (4) is first filled before substituting the switching pressure-system pressure-by a pressure depending on the centrifugal force and present in both pressure chambers so that, as a function of this centrifugal force, different transfer moments are generated which also act particularly in case of traction (high rotation speed) and thrust (idling). The pressure chambers (4, 6) are connected on large cross sections (41, 61) to a filling and emptying valve (3) by means of which the radially outer pressure chamber (4) is filled and emptied, whereas the radially inner pressure chamber (6) is only emptied. Thereby, it is possible to simplify the control which is a function of the running conditions upon a relatively low system pressure due to the pressure transfer depending on the centrifugal force, and to accelerate the control by emptying both pressure chambers also up to the transfer of the maximum possible motor torque.

摘要： A servo steering, particularly for motor vehicles, comprises amongst other things a pilot valve with two valve pistons (45, 46). The valve has a feed connection (5), a return connection (16) and, between said connections, a connection (10, 11) for both sides of a servo motor (14). A reaction chamber (24, 25) is adjacent to each front side of the pistons (45, 46). The reaction chambers (24, 25) are close to the pilot valve positions situated between an inlet pilot opening (19, 20) and a reaction pilot opening (22, 23). The steering is further comprised of a controllable reaction device wherein the reaction chambers (24, 25) are hydraulically separated from each other by fixed restrictions (36, 37) and are connected by one of the fixed restrictions to a common control member (38) of which the restriction cross-section varies according to the driving speed. Controllable non-return valves (30, 31) are arranged in the direction of the respective reaction chamber, on one hand between the reaction chambers (24, 26) and on the other hand between the working spaces of the servo motor (14) which are connected to the chambers. A restriction (30, 31) is arranged between the connections (10, 11) for both sides of the servo motor (14) and the connection position (28, 29) for the reaction chambers (24, 25). With such a servo-controlled steering, not only the hydraulic reaction may be controlled by also the operation of the servo.

摘要： The braking device (15, 16, 17) arranged within a wheel head (2) having within a hub-shaped casing (1) a reduction/planetary gear (6) at the end of a differential shaft (4) enables, by means of an axial segmentation, both a larger number of possibilities for the equipment in large series of prefabricated shafts and an improvement of the efficiency of the braking device when the manufacturing and maintainance conditions are improved, without affecting the construction speed, respectively the compactness of the wheel head. On the sleeve-shaped link portion (17) which rigidly connects the axle shaft portion (4A) to the sun wheel shaft (4B) which extends it, there is arranged on the substantially enlarged diameter (preferably almost on the middle of the planet pinion carrier shaft (7)) a brake support toothed crown (20), thereby providing annular surfaces of brake disks, for double purposes. Even for high speeds, this may be designed with a particularly thin configuration and with spring self-return owing to the short mounting thereof between the inner toothing (9) of the inner toothing wheel (10) and the raised brake support toothed crown (20) without any danger of oscillation of wobbling. Upon higher sollicitations, a more intensive cooling is provided by the lubricating oil which accumulates outside the drive. On the sun wheel toothing (5), a slot (43) situated between the hollow shaft (12) and the differential shaft (4) is closed by means of the link portion (17) by means of a lip seal (44) and a static and direct adherance link is produced between the cap (3) and the hollow shaft (12).

摘要： The invention concerns a suspension for vehicle wheels with wide tyres, e.g. low section tyres or double tyres. On utility vehicles with double tyres, rigid axles are almost always used. These axles have the advantage that variations in wheel loading are low. They suffer from the particular disadvantage, however, that the ground clearance is limited by the bridge design. Another disadvantage is that an uneven road surface has an adverse effect on relative wheel loading. The aim of the invention is to provide a suspension which has the advantages of the rigid axle without suffering from its disadvantages. The suspension (1) proposed is thus characterized by the provision of an additional degree of freedom which permits the wheel carrier (20) to execute an oscillating motion about a swivelling axis (10). The swivelling axis (10) lies approximately at the centre of the wheel (2) and extends approximately at the level of the plane of the road surface (8). The design proposed has the particular advantage that the wheel adapts automatically to the road surface. Variations in wheel loading caused by transverse forces are therefore low.

摘要： The dimensional effect on quenching with pin or swage hardening tools is favoured and automatable both towards a closer tolerance on the final dimensions and towards a more flexible adaptability to larger variations in the raw dimensions in that there are at least two successive hardening stages (T1, T2) in shrinkage, the first of which takes place over a larger diametric range (6) and causes purely plastic deformation, while the second (T2) has to assume only partial plastic deformation. The tools involved are both fixed pins (5) with two diameter ranges (6, 7) and auxiliary force operable spreading pins (16) or corresponding matrices adjustable to smaller cylindrical dimensions during hardening. The risk of tool damage or structural breaks resulting from excessive shrinkage drops and the proportion of rejects within narrow final dimensional tolerances is reduced with a shorter and more economical plant running-in time with new workpieces.

摘要： The invention concerns a pressure cut-off device in the end positions of the steering lock in a power-assisted steering system. In steering systems with a working piston (2) which slide in the steering housing, this cut-off device is installed in a through bore (17) in the working piston (2). A cut-off valve (20, 22 or 21, 23) actuated by a ram (24 or 25) which strikes against a wall (30 or 31) is provided for each steering direction. To avoid time-consuming adjustment of the cut-off valves (20, 22 or 21, 23), bolts (40 and 41) with press-fitted bushing (32 and 33) which act as limit stops are screwed into the walls (30 and 31). After the power-assisted steering system is installed in the vehicle, the bushings (32 and 33) can be pressed automatically into the end position corresponding to the steering angle. To this end, after preliminary fitting of the bushings (32 and 33) on the bolts (40 and 41) and after the combination so obtained is screwed into the housing (1) with the front axle jacked up, the vehicle is first steered against the wheel stops without power, during which time the working piston presses the bushings (32 and 33) onto the bolts (40 and 41) to the extent required for cutting off the power. As the rams (24 and 25) of the cut-off valves (20, 22 or 21, 23) project beyond the working piston (2) by a distance 'x', the power is switched off shortly before the wheel locks are reached.
