Rexroth A6VE55 axial piston variable hydraulic motor

The A6VE55 is a variable displacement motor with an axial tapered piston rotary group of bent-axis design. Unlike the more common swashplate design, the bent-axis concept angles the cylinder block relative to the drive shaft. This geometry inherently results in lower internal friction and allows for higher starting torques and more robust bearing systems, translating to a longer service life in demanding conditions. This is particularly critical in applications where the motor is subject to high shock loads and continuous operation.

The Hallmark of the A6VE: Function and Precision

Beyond raw power, the A6VE series is defined by its control capabilities and robust engineering.

Infinite Variability and Control

The hallmark of the A6VE series is its ability to vary displacement infinitely from Vg max to nearly zero. This is achieved through a wide array of control devices, allowing for advanced features like continuous variable transmission (CVT), power limitation, and soft start/stop sequences. For instance, the EZ control type signifies electro-hydraulic proportional control with a position feedback sensor, enabling a closed-loop system for extremely precise and repeatable displacement adjustments.

Versatility in Application

The A6VE55 is a versatile component that thrives in both open and closed-circuit hydrostatic transmissions. Its design also lends itself to integration; it can be used as a plug-in motor that slides directly into a mechanical gearbox, saving space and simplifying installation. This "plug-in" capability is often used in travel drives and winch drives, where the motor is coupled with a planetary gearbox to provide the necessary torque for moving heavy machinery or lifting loads.

Real-World Applications

Understanding the theory is one thing, but seeing the A6VE55 in its natural habitat is where its true value shines.

Construction & Earthmoving: It is a critical component in the final drives of excavators, track loaders, and bulldozers, providing the high torque required to move the machine and the precise speed control needed for complex operations. An excavator, it allows for smooth, controlled travel even on steep inclines and challenging terrain.

Material Handling: In cranes and forklifts, the motor's ability to provide a steady, high torque at low speeds is invaluable for precise load placement and safe operation.

Industrial Hydraulics: Its robustness and variable speed control make it suitable for stationary applications, such as injection molding machines and mining equipment, where consistent hydraulic power is crucial.

Selection Table

Q1: What is the fundamental design difference between the Rexroth A6VE55 and a swashplate-type hydraulic motor, and what practical advantage does this provide?

A1: The A6VE55 uses a bent-axis design, where the cylinder block is angled relative to the drive shaft, rather than the more common swashplate design. This geometry results in lower internal friction, higher starting torque, and more robust bearing systems. The practical advantage is a longer service life under demanding conditions, particularly in applications subject to high shock loads and continuous operation, such as earthmoving equipment.

Q2: What is the "plug-in" capability of the A6VE55, and how does it benefit system designers in terms of installation and space?

A2: The "plug-in" capability means the A6VE55 motor can be slid directly into a mechanical gearbox without requiring additional coupling or mounting hardware. This design simplifies installation, saves significant space within the machinery envelope, and reduces the number of components required. It is particularly beneficial in travel drives and winch drives, where the motor is directly mated with a planetary gearbox to deliver the required torque in a compact, integrated package.
