Military Flexible Frame

The Multidrive Flex Frame is a unique system that allows drive between a rigid truck and trailer, allowing for 8×8, 8×10 and 10×10 drive configurations.

Multidrive have developed the complete system including the prime mover / tractor unit – connecting Flexible-Frame assembly and driven trailer.

Additionally standard trucks and trailers can be adapted to incorporate the Flexible-Frame technology.

The Flex-Frame coupling system delivers a drive from the rear tractor through drive axle to the leading tandem trailer axle. When compared to a rigid vehicle of similar proportions this system dramatically improves mobility, manoeuvrability and agility.

In addition to allowing drive to the trailer unit the design also enables:

  • Unlimited oscillation between tractor and trailer, which improves wheel to ground contact, enhancing traction
  • Increased axle spacing giving a wider spread of traction
  • Enhances lateral stability in all yaw and pitch circumstances
  • Smallest turning circle in its class with only one steer axle and minimum cut-in

The Multidrive Flex-Frame has three planes of movement to achieve:

  • 50 degrees up & down
  • 50 degrees side to side
  • 360 degrees rotation

Additional features

 

  • Low stress – increased chassis life compared to a long rigid chassis
  • Active optimisation of all axle loadings, particularly on second axle
  • Improved strategic and tactical mobility
  • Legal GVW/GCW allowing for high payloads
  • 40 degree ramp profiles achieved with reduced stresses
  • Lower overall chassis stresses – minimising chance of load or chassis feature
  • Safe high speed characteristics
  • All-wheel-drive toque split, with cross and longitudinal axle differential locks
  • Easy disconnection
  • Easy maintenance
  • Utilises standard vehicle steering
  • Legal and safe throughout the total use spectrum
