Horizontal drive types with a focus on the "differential drive module"

Horizontal drive with differential drive module

In the case of a differential drive module, the vehicle is steered by speed differences of the two rigid drive wheels – similar to the principle of a tracked vehicle. Swivel casters at the front and/or rear keep the system stable. Disadvantages include restrictions on maneuvering capabilities, load distribution and longer times required for complex maneuvers.

  • Inexpensive mechanics
  • Limited maneuverability
  • Straight and reverse travel
  • Rotating around the center axis possible

Horizontal drive with differential drive module and steering drive module

In the case of a horizontal drive with differential drive module and steering drive module, the drive force is supplied exclusively via the differential drive module.

  • Inexpensive mechanics
  • Good load distribution
  • Precise maneuverability
  • Moderate payload

Horizontal drive with differential and travel/steering drive module

In the case of a horizontal drive with differential and travel/steering drive module, the drive force is supplied via both the differential drive module and the travel/steering drive module.

  • Good load distribution
  • Precise maneuverability
  • Higher payload

Horizontal drive with differential and turntable drive module

In the case of a horizontal drive with differential and turntable drive module, the drives of the turntable drive module are installed on a slewing gear. The differential drive module on the 2nd axis provides additional propulsive power and more precise steering.

  • Dynamic even with high loads
  • High tolerance for load distribution
  • More precise steering and positioning
  • Smoother handling than a horizontal drive with only a differential drive module
