Rely on tested quality and order planetary gearboxes, covers, seals and matching components online.

Power amplification on the wheel

An external planetary gearbox supplements the axle drive with an additional transmission ratio directly on the wheel hub. It distributes the torque via planetary gears around a sun gear, resulting in a compact, power-splitting solution (see planetary gear principle).
This reduction ratio on the wheel increases the available torque on the wheel axle and reduces the load on upstream components such as cardan shafts or the main gearbox.

Integration and construction technology

For smooth operation, the planetary gears, ring gear, sun gear and housing cover must be precisely matched to each other. Seals, O-rings and cover seals ensure that the gear oil remains in the system and no leaks occur. Examples of O-rings, cover seals and shaft seals for planetary gearboxes are listed in workshop spare parts catalogs.

What should you look out for when buying:

TRANSLATION

Make sure that the gear ratio (e.g. 5:1, 6:1 etc.) matches your vehicle concept and intended use to ensure optimum performance and durability.

SEAL DESIGN

Check which cover types (metallic, cast parts) and sealing solutions are used – a high-quality cover prevents oil loss and offers a long service life.

MATERIAL

Pay attention to the quality and material grades of the planetary gears, tooth flanks and rear gearbox parts – they have a decisive influence on operational stability and smooth running under high loads.

Strengthen your wheel reduction!

With the right planetary module, you can give your vehicle more torque at the wheel and reduce the load on central components. Discover high-quality modules, covers and seals – precisely matched to your axle performance.
