Bosch Rexroth A6VE variable hydraulic motor for Wirtgen Surface Miner 140077 115302 172618 192791 2077526 2098742 2111364

The A6VE series is more than a simple hydraulic motor; it is a masterpiece of axial piston engineering built to withstand the demands of heavy machinery. Its robust bent-axis design and high-pressure capabilities are specifically tailored for mobile applications like the Wirtgen 220 SM and its larger counterparts.

The Bent-Axis Principle and High-Pressure Capability

The A6VE's strength lies in its axial tapered piston rotary group, a design that ensures high efficiency and durability under extreme loads. Capable of handling nominal pressures up to 450 bar and maximum pressures of up to 500 bar, this motor converts hydraulic power into the immense torque required to drive the cutting drum and traction systems through abrasive materials. For a Wirtgen Surface Miner, which relies on high-volume hydraulic pumps to maintain consistent power output, this pressure rating is paramount.

Plug-In Integration and Compact Design

A key feature of the A6VE series is its "plug-in" design. The motor features a recessed mounting flange designed for seamless integration into mechanical gearboxes, creating an exceptionally space-saving construction. This allows for a direct, compact connection that reduces the overall footprint and weight of the drivetrain, a critical factor for balancing the Wirtgen miner's heavy-duty structure.

Maximizing Productivity: Variable Displacement and Control

The "variable" in the A6VE's name is where the magic happens for productivity. Unlike fixed-displacement motors, the A6VE can alter its displacement to match the operational demands of the mining process.

Torque Versus Speed: The Control Range

The A6VE offers a wide control range, capable of swiveling to zero displacement. This allows the motor to adjust seamlessly between two critical states: high torque at low speeds for cutting through dense material, and high speeds for maneuvering or lighter cutting passes. The motor's ability to vary displacement via hydraulic, electric, or automatic controls gives the operator the finesse needed for selective mining, ensuring precise extraction without unnecessary wear on the equipment.

Q1: How does the A6VE improve the efficiency of a Wirtgen surface miner?

A1: The A6VE's variable displacement allows it to adjust the ratio of speed and torque dynamically. This means the motor only uses the required amount of hydraulic fluid and pressure for the task at hand, reducing energy waste and heat generation while optimizing the cutting drum's performance.

Q2: What optional control features are available for the A6VE?

A2: The motor can be equipped with various controls, including hydraulic or electric proportional controls (HD, EP), two-point controls (HZ, EZ), and automatic controls related to speed or high pressure (DA, HA). It also supports optional features like flushing valves, boost-pressure valves, and counterbalance valves to enhance system safety.

Q3:What is the price and delivery time of the A6VE hydraulic motor for Wirtgen Surface Miner？
