Bevel Gearbox Drives target electrical vehicles.
Press Release Summary:
Developed as integrated traction and steer drives for use in mobile machines, Drive Platforms TPD 230 and TBD 254 feature wheel diameters of 230 and 254 mm, respectively. Both electrically steered, modular units incorporate induction motors, manufactured for specific vehicle battery voltage, and integrated holding brake. With minimal torsional backlash, drives provide low-noise operation. Output ranges are 1.2-2.5 kW on TBD 230 and 1.5-3.2 kW on TBD 254.

New Bevel Gearbox Drives for Electrical Vehicles
Energy Efficient and Compact Traction and Steer Drive Units
ABM Greiffenberger introduces two new platforms of Bevel Gearbox Drives developed as integrated traction and steer drives from the ground up for use in mobile machines. Key features include high efficiency, compact design and long life. A modular design provides OEM's with maximum flexibility for easy adaptation to the requirements of their vehicles.
What are users of electrical pallet trucks or sweeper/scrubbers expect from drive units? /They expect high output with minimum power consumption. Of equal importance are minimal maintenance needs and long life without failure. Additionally, vehicle OEMs require a com-pact design, easy integration into their vehicle and favorable cost even for special versions and unique options.
Output Range from 1.2 to 3.2 kW
All these requirements were considered from the be-ginning when ABM Greiffenberger designed the new Bevel Gearbox Drives. They were conceived as integrated traction and steer units for mobile applica-tions. The impressive result is now introduced to ve-hicle OEMs and the press.
The new electrically steered Drive Platforms TBD 230 and TBD 254 differ from each other by the wheel diameters of 230 and 254 mm.
Both incorporate powerful induction motors, manufactured for a specific vehicle battery vol-tage, an integrated holding brake and a modular design.
On the TBD 230 the output ranges from 1.2 to 2.5 kW, and on the TDB 254 from 1.5 to 3.2 kW.
Adaptable to OEM Requirements
Modular designs create the foundation to manufacture customer specific drive units even in small and medium volumes. It also provides the OEM the possibility to offer different drive options to end users. For example fixed motors can be used for traction as well as steer func-tion. Motors are available with sensor bearings or coils and even the integration of customer supplied sensors is possible. Due to the modular design individual custom execution can be realized at reasonable cost.
On both platforms the complete Motor-Brake-Gearbox-Unit requires minimal space allowing for compact vehicle designs. This also provides for high static wheel loads assuring outstand-ing traction attributes.
Gearboxes excel with outstanding efficiency and minimal torsional backlash. This is not only critical for high efficiency but also low noise operation.
High Vertical Integration
Typical for all ABM drives is the high vertical integration: Gearing, available on each platform in three different ratios, are manufactured completely in house, likewise aluminum die cast parts are produced in our own foundry.
Development and manufacturing of high value electrical motors is also part of the core com-petencies of a systems supplier that operates with the motto "The Single Source for all Your Drive Needs" and "Made in Germany". This is the foundation for the high quality and relia-bility of ABM Drive Systems.
Developed with the Latest CAD- and Simulation-Tools
For the development of the gearboxes the latest CAD programs and simulation tools, e.g. An-sys 12 for FEM analyses and KissSoft as well as FVA Work Bench for gearing calculations, were used. For final inspections of complete drive units, high-precision measuring machines and a brand new test bench - installed in 2010 - are available allowing 100 % inspection of the most complex drive units.
In Marktredwitz a new assembly and manufacturing line for the bevel gear sets is currently being set up that will guarantee a continuous high quality level. To optimize assembly flex-ibility, assembly processes have been adapted to the modular design of the ABM drive units.
Decades of Know-How as Systems Supplier for the Material Handling Industry
The new bevel gearbox drives fully exploit the possibilities offered by new drive technologies - they excel with a high quality level that will satisfy even the most demanding OEMs and end users. As a systems supplier ABM Greiffenberger could draw from comprehensive indus-try know-how for these designs.
When it comes to long life and availability experiences made in other industries such as hoist technologies and wind turbines influenced the development. ABM also supplies complete drive systems to these very demanding industries.
Advantages of Cooperating with a Systems Supplier
Besides technical benefits of the drive units ABM Greiffenberger also offers with the new platforms economic advantages: For vehicle OEM's purchasing complete traction and steer units with matched components signifies reduced engineering, interface work as well as sig-nificantly reduced assembly - optimum conditions for smooth engineering and manufacturing.
