Heavy-Duty Planetary Hub Reduction Axle – Next-Level Drive Technology

Heavy-Duty Planetary Hub Reduction Axle – Next-Level Drive Technology

Released: 04. October 2019

Our drive technology for construction vehicles has reached the next level thanks to the new heavy-duty planetary hub reduction axle! A shorter gear ratio means that the remote-controlled trucks can be steered even more precisely through extremely difficult terrain. We will be showcasing our planetary hub reduction axle at the Faszination Modellbau trade fair in Friedrichshafen.

Shorter gear ratio for greater drive power

Our remote-controlled trucks can show what they really are made of on off-road excursions. A powerful motor, precise control and stable components are required to master any obstacle without causing damage. To make navigating through uneven terrain even easier in the future, we have developed an axle for our off-road construction vehicles that raises the driving experience to a whole new level: the heavy-duty planetary hub reduction axle!

The name says it all with the planetary hub reduction axle – it meets even the most extreme terrain requirements. The total gear ratio of the axle is 1:5. This shorter gear ratio means that the models can be steered more sensitively when maneuvering in difficult terrain. Likewise, with the same engine power, approx. 65 percent more drive power is applied to the wheels, relieving the entire drive train at the same time. The extremely high torque is only generated in the planetary hub gear of the axles. Here the ratio is about 1:3, so that the load on the differential and lock is only one-third as high.

The Heavy-Duty Planetary Hub Reduction Axle at a Glance

  • All gears, lock and universal joints are made of hardened steel.
  • The robust housing is made of stainless steel and has a very small diameter of only 28 mm to allow greater ground clearance and thus improved off-road mobility.
  • The axles are equipped with extra-large ball bearings in the wheel hubs, which guarantees high loads.
  • The axle drive is in the same direction without reversing the direction of rotation of the cardan shafts.
  • The kingpins in the front axle are mounted at an angle to improve the steering geometry. This results in lower actuating forces for the steering servo and a smaller turning circle.
