Electronified up to 530 bar for the travel drive of the future

With its integrated sensors, the new A4VG series 35 from Rexroth is already designed for the requirements of future travel drives.

Rexroth A4VG series 35 axial piston variable pump for electronified travel drives

The new A4VG series 35 axial piston variable pumps from Rexroth already fulfill the upcoming requirements for electronified travel drives with their integrated sensors and higher burst strength. With these features, they support the trend towards ever-closer networking of motor and machine control with the travel drive. Whether they are used as an individual component or as a complete solution together with optimally adapted hydraulic motors and the new, preprogrammed travel drive software from Rexroth, they reduce the time and money spent on engineering new drive concepts.

The trend is clear: More and more manufacturers of compact construction machinery and municipal vehicles are working on new travel drive concepts with higher working pressures and electronic control. Their aim is to bring down consumption and exhaust emissions while improving driving comfort. In addition, by transferring the majority of functions to the software, they reduce variance with regard to assembly. Depending on the customer's order and requirements, it is possible to enable certain program functions on identical hardware.

The new A4VG series 35 axial piston variable pump is designed for these future requirements. The developers at Rexroth have integrated an extensive sensor package into the short pump, which simplifies the electronification of travel drives in closed circuits. Offering a nominal pressure of 400 bar and a maximum pressure of 530 bar, the pump meets machine manufacturers' demands for higher pressure levels. Moreover, it was developed on the basis of the proven series 32 rotary groups in swashplate design and covers sizes 40 to 90. A further benefit is the design for travel drives, which has been optimized using load collectives. This results in a compact design and high power density.

Together with high-efficiency hydraulic motors of the A6VM series and the new DRCA4x travel drive software, Rexroth also offers complete solutions for travel drives from a single source. All of the components are optimally adjusted to one another and all basic functions have already been predefined in the software. This reduces engineering time and costs and, in most cases, makes complex programming a thing of the past. The machine manufacturers have only to define the series-specific parameters.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 33,700 associates generated sales revenue of approximately 5.6 billion euros in 2014.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.

Linear motion, short time to market

Stand-alone linear axes are the trend. The combination of electrical drive unit and mechanical or hydraulic cylinder reduces installation space and engineering time and combines our specific professional knowledge in one system. With ready-to-mount and i4.0-enabled solution packages, Bosch Rexroth is in line with the current market requirements regarding electrification, digitalization and monitoring as well as condition-based maintenance. The uniform control and drive concept which is used in the different technologies serves as a basis for a short time to market and the economical implementation of hybrid solutions.
