5.1 Performance description

The Variable plug-in motor converts hydrostatic flow into mechanical rotation. It is

designed for mobile applications such as construction machinery.

Refer to data sheet RE 91606 and the order confirmation for the technical data,

application conditions and operating limits of the axial piston unit.

5.2 Product description

The A6VE is an Variable plug-in motor with axial tapered piston rotary group

of bent-axis design for hydrostatic drives in open and closed circuits. For axial

piston units with bent-axis design, the pistons (8) are arranged at an angle to the

drive shaft (1). The pistons rest directly on the drive shaft where they generate

torque depending on the pressure and swivel angle. The specific torque and

displacement can be changed by adjusting the bent axis.

In the open circuit, the hydraulic fluid flows from the reservoir to the hydraulic

pump from where it is transported to the hydraulic motor. From the hydraulic

motor, the hydraulic fluid flows directly back to the reservoir. The output direction

of rotation of the hydraulic motor can be changed, e.g. by a directional valve.

In the closed circuit, the hydraulic fluid flows from the hydraulic pump to the

hydraulic motor and from there directly back to the hydraulic pump. The output

direction of rotation of the hydraulic motor is changed, e.g. by reversing the flow

direction in the hydraulic pump.
