WHEEL GEARS
Reggiana Riduttori Wheel Gears are integrated planetary final drives specifically designed for mobile machinery requiring high traction capability, compact dimensions, and long-term reliability under severe operating conditions.
Unlike general-purpose industrial gearboxes, Wheel Gears operate as a structural and functional element of the machine, directly supporting vehicle weight while transmitting torque to the wheel. This dual role makes them a critical component in mobile applications where space constraints, load concentration, and dynamic stresses are dominant design factors.
Reggiana Wheel Gears combine planetary reduction technology with robust bearing systems, optimized sealing, and application-oriented configurations to ensure consistent performance throughout the machine’s service life.
Wheel Gears perform a core functional role within mobile machines by converting motor output into usable traction at the wheel while simultaneously sustaining mechanical loads generated during operation.
Their primary functions include:
Because Wheel Gears are installed at the final stage of the driveline, they are continuously exposed to variable loads, frequent load reversals, and harsh environmental conditions. For this reason, their design prioritizes mechanical robustness, load distribution efficiency, and operational reliability over extended duty cycles.
Wheel Gears are used in a wide range of self-propelled and mobile machines where reliable traction and compact integration are essential.
Typical applications include:
Construction machinery
(wheel loaders, compact loaders, road construction equipment)
Aerial platforms and access equipment
(scissor lifts, articulated and telescopic platforms)
Material handling vehicles
(self-propelled carriers, industrial transport vehicles)
Agricultural and forestry machinery
(harvesters, forestry carriers, specialized off-road vehicles)
Mining and heavy mobile equipment
(service vehicles, underground machinery, auxiliary transport units)
In all these applications, Wheel Gears are selected based on machine architecture rather than purely on gearbox performance data, making application-driven engineering a fundamental selection principle.
The Reggiana Riduttori Wheel Gear range is structured to cover a broad spectrum of machine sizes, operating weights, and traction requirements.
The product range includes multiple sizes and configurations, allowing designers to balance:
The progression of sizes follows a scalable mechanical logic, ensuring consistent design principles across the range while adapting load capacity, bearing dimensions, and torque capability to specific application needs.
This modular approach enables OEMs to select the most suitable Wheel Gear without oversizing, optimizing both performance and overall machine efficiency.
Reggiana Wheel Gears are based on a planetary reduction architecture, selected for its high power density and balanced load distribution.
Key technical features include:
This technical concept ensures that the Wheel Gear operates reliably as both a transmission element and a load-bearing component, even under continuous and intermittent heavy-duty conditions.
To meet diverse machine architectures and drive concepts, Reggiana Wheel Gears can be supplied with a wide range of integration options.
Available configurations include:
These options allow Wheel Gears to be adapted to conventional hydraulic machines as well as modern electrified platforms, ensuring compatibility with current and future mobility concepts.
The correct selection of a Wheel Gear is based on a machine-oriented evaluation, rather than gearbox data alone.
Key parameters typically considered during selection include:
By analyzing these parameters together, the Wheel Gear can be matched precisely to the application, ensuring optimal performance, durability, and efficiency throughout the machine’s operating life.
Reggiana Riduttori Wheel Gears are engineered and manufactured according to strict quality standards, with a strong focus on reliability in demanding mobile applications.
Core reliability principles include:
All Wheel Gears are developed and produced in Italy, reflecting Reggiana Riduttori’s long-standing expertise in planetary reduction technology for mobile machinery.
