Single roller 4WD dynamometer
High-end, modular test bench with mechanical link system
Features highlight
- 630mm [24,8″] rollers
- 330km/h [205mph]
- 2500HP wheel power
- mechanical bevel-gear link
The dynoKRAFT A380-4WD-ML automotive chassis dynamometer is the absolute leader in the marked for high-end AWD test benches.
It supports longest wheelbase and widest track among all dynamometers currently found on the market.
It’s modular design enables upgrade from A380-2WD over to 4WD and mechanical link in 3 steps.
The mechanical link system was engineered using angular bevel-gear gearboxes and custom cardan shaft. Any axis can be manually disabled using hand-lever. No noisy belts, greasy chains!
The defaults installation type in PIT. The dynamometer is delivered with all required installation material and metal grating for the pit-installation.
Floor-top installation or combination with 4-post is lift available on request.
Roller width of 2200mm allow to test even wide-body GT race cars without problems.
Wheelbase range: 2200-3300mm (true wheelbase – without need to use roller tangent)
With two 3300Nm (optional 3800Nm!) eddy current brakes the A380-4WD-ML automotive chassis dynamometer allows to test up to 2500HP (1250whp on both rear and front axis).
All retarders are constantly cooled by built-in fans.
The roller diameter of 630mm reduces tire wear drastically and help keeping the tire temperature under control during long test sessions.
The dynamometer comes equipped with pneumatically actuated wheel-bumper that supports the vehicle during setup.
An built-in LED underbody illumination provides clear view during vehicle strapping.
The dynoKRAFT A380-4WD-ML can be freely configured with extension modules (additional inputs, OBD Interface etc…) to match customer needs thanks to our upgradable design concept.
