Abstract: An adjusting device of an axial piston machine having a displacement volume that is adjusted by a pivoting yoke. The adjusting device has a cylinder, which is radially spaced from and tangential to the yoke pivot axis. A piston communicates with the yoke and is adjusted by hydraulic pressure change. A control arrangement has a position regulating valve with a control piston which can set the hydraulic pressure acting on the piston. A mechanical return can transfer the yoke pivoting position to the control piston. The valve is axially parallel to the cylinder and radially spaced from the yoke pivot axis. The return comprises an axially movable sensing piston and coaxial return spring which are axially adjacent to the valve. The sensing piston abuts a yoke surface that is eccentric with respect to the pivot axis and connected to the control piston by the return spring.

Abstract: A power distribution transmission unit (1) having a hydrostatic power branch (2) and a mechanical power branch (3) connected by a connection system (8). The connection system (8) at least partially damps transfer of oscillations between the power branches. The power flow can be passed between the power branches, via a connecting shaft (22) that compensates axial offset between a hydrostat shaft (18) of the hydrostatic power branch (2) and a mechanical branch shaft (20) of the mechanical power branch (3). The connecting shaft (22) is a hollow shaft and a spring device (27), elastically prestressing the hydrostat shaft (18), is arranged within the connecting shaft. The tooth profiles (23, 25) of the connecting shaft (22) are formed as curved outer teeth which engage in tooth profiles (24 and 26) of the hydrostat shaft (18) of the hydrostatic power branch (2) and of the shaft (20) of the mechanical power branch (3), in each case made as inner teeth.
