Performance chassis dynos (R&D)

Our technologies for your demands

Single-roller chassis dynamometers bring the field into the laboratory. Large rollers, highly dynamic drives and state-of-the-art control technology enable very realistic and reproducible driving simulation for all agricultural vehicles from tractors to combine harvesters. In vehicle development (R&D), a wide variety of load profiles can be investigated even before the first road trip or real field measurements can be reproduced on the test bench.

An additional electrical load unit on the rear PTO enables any attachments to be simulated on the test rig. A hydraulic pull-down device on the front axle can be used to simulate real plowing operations.

The tests to be carried out in the development process are vehicle and customer dependent and may include, for example, the following topics:

  • Performance and functional measurements
  • Endurance measurements
  • Simulation of uphill driving under full load or braking operation during downhill driving
  • Simulation of different field works
  • Simulation of changes in driving direction
  • Single wheel measurements
  • Investigations into the vertical dynamics of vehicles and the longitudinal compliance of wheel suspensions
  • Fuel or electric power consumption measurements
  • Dynamic investigations of driver assistance systems

RENK chassis dynos can also be installed in the following test chambers if prepared accordingly:

  • Climatic chambers
  • EMC measuring chambers
  • NVH test chambers
  • Wind tunnels
  • Altitude chambers

The rollers can be single-driven, in pairs or per axle, depending on the application. The number of rollers is predetermined by the vehicles to be tested. The distance between the rollers is adjustable to the wheelbase of each individual vehicle.

The RENK RDDS test stand automation system can manage all common test programs as well as self-assembled test runs.

01 “True Turnkey” service

“True Turnkey” service exactly according to customer needs

Depending on their intended use, complete vehicle test stands also require extensive infrastructure on the building side (foundations, test chambers, exhaust and air-conditioning technology, power and media supply, etc.). In addition, a wide range of measurement equipment has to be integrated and automated test runs created. For us, "true turnkey" means clarifying with the customer all the necessities of his test stand project and processing an optimum scope of services for the customer. From the basement to the roof. From planning to implementation.

02 Modular and expandable

Modular and expandable test system for a wide range of testing tasks

The change of test requirements goes in line with the further development of the vehicles. For this reason, complete vehicle test stands, which are usually operated for decades, must have a very high flexibility. The adaptation of new specimens or the modification of test programs can be carried out by the operators of our test benches themselves. For more extensive adaptations, our experienced service team is at your disposal.

03 Unique compact design

Unique compact design

Through constant exchange of experience with our customers and continuous further development of our drive solutions, we can offer uniquely compact vehicle test benches today. Our test stands require the minimal amount of ground work in their performance range. For this reason, RENK test stands are also perfectly suited for retrofitting in existing buildings. And in new buildings, too, less ground work naturally means lower costs.
