Valeos Reducer Tech Enhances EV Torque and Efficiency

Imagine an electric vehicle's motor as a tireless dancer, requiring a precise partner to control its rhythm and transform raw power into smooth, efficient motion. This essential partner is the gear reducer—the unsung hero of electric mobility that performs functions far beyond what traditional transmissions offered in combustion engine vehicles.

Commonly called gear reducers or transmissions, these components serve as the vital link between motor and wheels. Their primary function involves adjusting motor speed and delivering optimized torque to the drivetrain—converting high-speed, low-torque input into the low-speed, high-torque output wheels require. While structurally simpler than conventional transmissions, EV gear reducers critically influence acceleration, range efficiency, and driving dynamics.

With decades of automotive systems expertise, Valeo has engineered gear reducers that achieve exceptional balance between cost efficiency, delivery timelines, and operational reliability. The company's solutions excel through meticulous optimization of these key parameters:

• Efficiency: Achieving 97% energy conversion efficiency minimizes power loss, directly extending vehicle range.
• NVH Performance: Advanced gear geometry and precision manufacturing dramatically reduce noise, vibration, and harshness for superior cabin comfort.
• Power Density: Compact designs deliver higher output within smaller footprints, supporting vehicle lightweighting strategies.
• Shift Quality: Multi-speed variants provide seamless gear transitions without perceptible interruption.
• Cost Competitiveness: Value engineering maintains premium performance while optimizing production economics.

Valeo's comprehensive product portfolio accommodates torque requirements from 700Nm to 4,500Nm, serving varied vehicle architectures through specialized features:

• Active Cooling: Temperature management systems enhance durability under demanding conditions.
• Disconnect Functionality: Decouples the driveline during coasting to minimize energy losses.
• Park Lock Mechanisms: Integrated safety systems prevent unintended vehicle movement.
• Multi-Speed Configurations: Cost-effective designs optimize efficiency across speed ranges.
• Torque Vectoring: Enhances stability and handling precision through intelligent torque distribution.

These technological solutions serve an expansive range of electric mobility applications including passenger vehicles, commercial trucks, autonomous taxis, two-wheelers, robotic systems, and off-road equipment.

In the evolving landscape of electric propulsion, gear reducers have transformed from simple mechanical components into sophisticated systems that define vehicle character and capability. Valeo's engineering expertise continues to advance this critical technology, delivering solutions that balance performance, efficiency, and reliability—key enablers for the global transition to sustainable mobility.
