Advancing Driverless Transport Systems
by WITTENSTEIN with DS Automation
WITTENSTEIN Posted 05/28/2020
DS AUTOMOTION, with its automated guided vehicle systems (AGV), supports the new drive system (TAS) from WITTENSTEIN. Automated guided vehicle systems (AGV) are used by companies to move goods and materials from A to B. They appear to be able to find their own way and avoid obstacles and can move forward, backward and even sideways. The total weight of these vehicles is 2,8 tonnes. These TAS vehicles move by means of an electric drive.
MORE POSSIBILITIES WITH THE AGV DRIVE
Until now, AGV manufacturers have mostly assembled their drives using standard drives widely available on the market. This costs time and rarely ensures compact solutions with high power density and energy efficiency.
In addition, they often lack important equipment features such as redundant speed monitoring sensors, service brakes or integrated safety engineering. Thanks to the new TAS traction drive system from WITTENSTEIN, these limitations are a thing of the past.
DS AUTOMOTION – A WORLD-LEADING PROVIDER OF AGV
DS AUTOMOTION GmbH, based in Linz, Austria, has been specializing in the development and production of driverless transport systems for nearly 30 years and has become a world-leading provider in this sector. The company specializes particularly in the automotive, print and paper and hospital and healthcare sectors as well as intralogistics. The service offer includes first-line system implementations, which are based on the special requirements of the customers.

TAS IS THE DRIVE OF THE FUTURE IN AGV
At John Deere in Mannheim, DS AUTOMOTION GmbH has implemented a flexible and highly available transport solution for the installation of agricultural machinery engines. Here, AGV automated guided vehicles – powered by their WITTENSTEIN TAS - move heavy loads from one assembly station to the next. The TAS vehicles impress with their smooth running, low energy consumption and high reliability and availability. TAS therefore offers all the features which will become standard in the future concept for AGV drive solutions.
FOUR POWER CATEGORIES IN PLUG & PLAY DESIGN
Install, switch on, drive - with the TAS, manufacturers of driverless transport systems now have access to the full drive unit as an integration-friendly assembly.
The vehicle axles comprise two servo drives from the TPM+ product family and decentralized drive amplifiers from the simco drive series. The TAS product family offers systems solutions in four power classes and sizes. The drive systems allow for individual adaptations, such as regulating the gear reduction when using the motor encoder and when selecting bus interfaces or brakes. Customized variants are also possible. Applicable to all versions, TAS vehicles can not only drive, but also steer as they are structured with differential drives. Steering and turning the vehicle is made possible by a speed difference between both drives and the vehicle axle.
TAS SIMPLY OFFERS MORE
Applicable to all versions, TAS vehicles can not only drive, but also steer as they are structured with differential drives.
Steering and turning the vehicle is made possible by a speed difference between both drives and the vehicle axle. A full range of technical highlights makes the traction drive system an ideal choice for AGV automated guided vehicle systems. This means that gearboxes are integrated directly into the drive wheels. On the one hand, this allows for optimal capacity utilization and, on the other, makes the TAS very flat and compact. This is particularly beneficial when vehicles need to drive under the load to be carried - such as in hospital logistics. A further benefit is the low energy consumption: The less power that is consumed, the longer the driving cycle the AGV can offer and therefore the greater the availability.
