We change the transmission. You transform the system

Varionova develops next-generation, AI-ready transmission systems, that can revolutionize the mechanical systems they become part of. Our breakthrough RatioZero technology enables smooth, efficient, gearless control for mobility, machines and robots. But there's much more to it.

Why it matters

Traditional transmissions have high efficiency but fixed gears. CVTs offer stepless ratio variation, but with low efficiency because of inherent friction. We have created the first, commercially viable, gear-based CVT: continuous, but efficient. Our technology is a game changer and opens to countless new possibilities.

Continuous variation

Unprecedented approach based on the "split rotation" principle. First gear-based CVT.

Energy efficient

Optimal gearing + minimal friction -> improved overall efficiency and less heat.

High torque

The shape-based load transfer mechanism can be made to withstand any torque.

Effortless control

Shifting forces independent from load forces, for a smooth shifting under load and an easy control.

RatioZero Technology

RatioZero

A variable-ratio, gear-based, near-zero-backlash transmission for smooth, precise, stepless control. Designed for mobility, heavy-duty, and industrial automation.

  • Gear-like efficiency
  • High torque, high range system
  • Continuous ratio control
  • Effortless shifting under load
Crown Drive Technology

Crown Drive

A reversible self-adapting transmission, based on another clever variation of the epyciclic gearing. Designed for robotics, mobility, and other applications.

  • Torque-based switch
  • Modified epicyclic gearing, reversible
  • Ratio selection mechanism fast, reliable and low energy
  • Low acoustic noise and wear

Applications

Our technology adapts to diverse mechanical challenges across industries

E-bike hub transmission
E-bike Hub Drive

A never-seen-before transmission for e-bike: efficient as a cassette and smooth as a CVT, allowing optimal use of the motor and battery and a totally new pedalling experience.

EV
Integrated EV transmission

An efficient and compact CVT-type transmission, allowing for continuous ratio change thus keeping the working conditions optimal for the EV powertrain, maximising performance and range.

Power Take Off
Simple yet Efficient Power Take Off

The RatioZero allows to reverse the current approach to PTO: the engine can run at a fixed (optimal) ratio, and the highly-efficient CVT ensures to match the implement with high-efficiency, mechanical power transfer.

Electrohydraulics
Electrohydraulics Cost-reduction Enabler

Both conventional and electrified machines use this kind of sub-system, often with variable axle piston pumps. The RatioZero allows to shift to a constant speed motor and fixed displacement pump, saving space and costs.
