摘要： Disclosed is a power-branched transmission, particularly for agricultural vehicles such as tractors or similar, having a stepped planetary gear which is disposed between an input shaft and an output shaft and is used for dividing the power supplied at the input shaft onto a mechanical power branch and a hydraulic power branch. The hydraulic power branch is formed by two hydraulically interconnected, identical hydrostatic axial piston engines which can be selectively operated as a pump or an engine, can be swiveled within a predefined pivoting angle, and can be connected to the input shaft or the stepped planetary gear in a different manner via two respective clutches so as to cover different operating ranges or running steps. In order to obtain better efficiency in such a power-branched transmission, the two hydrostatic axial piston engines are configured as wide-angle hydrostats that are provided with a minimum pivoting angle range of 45°.

摘要： The invention relates to a hydrostatic axial piston machine having a cylinder block which can be rotated about a first axis, the cylinder block being provided with a plurality of cylinder bores which extend in the axial direction and which are arranged on a partial circle which is concentric in relation to the first axis, in addition to a plane which can be rotated about a second axis, whereon a number of pistons associated with the bores, can be articulated in a pivotable manner on a second partial circle which is concentric in relation to the second axis and form a ring. Also provided is a device for synchronizing the rotation of the cylinder block about the first axis and the drive shaft about the second axis. The cylinder block and the drive shaft can be adjusted in a continuous manner using both axes, between a first position, wherein both axes are parallel, and a second position, wherein both axes together form a maximum pivoting angle which is different from zero.

摘要： A steered and driven axle-end assembly has a steering knuckle whose inside and outside halves are pivotal about an upright pivot axis. An axle extends into the inside knuckle half and is connected to the inner side of a universal joint whose outer side is connected to one end of a gear train whose other end is connected to a wheel support which is rotatable about a horizontal wheel axis on the outside knuckle half. A pair of roller bearings centered on the wheel axis are spaced axially apart therealong by a spacing which is equal to at most half of the axial distance through which the outside knuckle half extends into the wheel support. Thus the outside knuckle half and associated structure can pivot through a considerable angle relative to the inside knuckle half for minimum turning radius of a vehicle embodying the axle-end assembly.

摘要： A steered axle assembly comprises a relatively fixed axle beam, a pair of wheel supports pivotal on the axle beam about respective upright wheel pivot axes spaced horizontally apart on the beam transverse to a predetermined horizontal travel direction, an at least limitedly articulated track rod extending horizontally transverse to the travel direction between the wheel supports and having outer ends pivoted on same about respective upright track axes spaced in the travel direction from the respective pivot axes, and an actuator cylinder fixed to the axle beam and having a piston rod forming part of the track rod for relatively displacing the rod and axle beam horizontally transverse to the travel direction and thereby generally identically pivoting the wheel supports about the respective wheel pivot axes. Respective rod and beam abutment formations fixed on the track rod and relative to the axle beam confront each other horizontally transverse to the travel direction. A stop or spacer fixed to one of the formations is engageable horizontally perpendicular to the travel direction with the other formation for limiting pivoting of the wheel supports in one direction relative to the beam beyond an end position with the spacer engaging the other formation.

摘要： This actuation of a differential lock consists essentially of the locking differential (10) and the coupling (11) connected thereto, which via an electromagnetic actuating means (12) connects that part of the locking differential (10) driven by the universal shaft when and as long as a predeterminable value of the steering angle is attained or exceeded. The sole signal generator used for this purpose may be, as required, realized as a contact built immediately into the switching circuit of the electromagnetic actuating means (2), or an inductive switch or potentiometer, respectively, in the area of the angle-dependent steering elements, and held fast in the axle housing (2), protected from damage. The switching means (7) is capable of being actuated either via further switches (17) and (30) manually by the driver, or may be combined with the engagement lever for the supplementary drive on steering axle (1) so that the locking differential (10) can only be actuated under appropriate driving conditions. The frequency of actuation of the locking differential (10) is thus limited to the essential cases of necessity, and a simpler and more robust engagement technique is achieved.

摘要： A continuously variable hydrostatic transmission (10) having torque division for a vehicle comprises a first hydrostatic unit (H1) operating as a pump and a second hydrostatic unit (H2) operating as a motor, and further a planetary drive (12), a first shaft (W1) on the drive side and a summing means (W6). The power present at the first shaft (W1) is divided by way of the planetary drive (12) to a mechanical transmission branch (Z9, W2, Z1, Z2) and a hydraulic transmission branch (Z7, W3, Z4, Z5, Z6, H1, H2) formed by the two hydraulically coupled hydrostatic units (H1, H2) and is combined again at the summing means (W6). In such a transmission, a compact and simplified design and great flexibility in application are achieved in that the power transmission between the first shaft (W1) and summing means (W6) can be controlled exclusively by varying the displacements of the hydrostatic units (H1, H2).
