Hook fixation and wheel hub fixation
The task of vehicle fixation is to fix vehicles with front, rear or all-wheel drive on various roller and belt test stands quickly, securely and without tension or play. Rod triangles and floor anchors firmly connect the vehicle to the test room floor. Fixation is achieved by friction locking of the stainless steel rods in EPDM shells. The rods absorb horizontal tensile and compressive forces, vertical forces do not occur. The fixation adjusts steplessly to the vehicle width, length and height.
S. Bleyer GmbH has developed two different vehicle fixation systems: The hook fixation as well as the wheel hub fixation. Both systems have been successfully used by the automotive industry and by test laboratories in the field of research and development since 1999 and 2005 respectively.
- Principle: Vehicle is fixed stress-free with backlash-free connections.
- Structure: rod triangles and floor anchors.
- Fixation: Friction fit of stainless steel bars in EPDM shells.
- Horizontal forces: Tensile and compressive forces are absorbed by bars.
- Vertical forces: Do not occur.
- Vehicle: Standard passenger car, prototype, test vehicle, motor vehicle without towing eyes.
- Vehicle mass: up to 3,500 kg
- Speed: max. 300 km/h
- Vehicle drive: front-wheel drive, rear-wheel drive, all-wheel drive, electric drive
- Roll: apex / double rollers, single / all-wheel rollers / belt test stands / single ram belt test stands
- Test: single-axle operation, dual-axle operation
- Test rig: endurance test, open-air test, wind tunnel, high-altitude climatic chamber (-40 °C to +50 °C), acoustic test rig
- Set-up time: Few minutes, fixation can be carried out quickly and easily by one worker
