MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202517073623 A) filed by Quaternion, Ingenieria De Sistemas Electromecanicos SL, Madrid, on Aug. 1, for 'bi-cycloidal gear power-split mechanism and e-bike hybrid powertrain having such mechanism.'
Inventor(s) include Carrasco Vergara, Pablo; and Peinado Martin, Diego.
The application for the patent was published on Aug. 22, under issue no. 34/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a simple and efficient bi-cycloidal power-split gear mechanism optimized for a hybrid powertrain with a low-speed power input, a high-speed power input/output, and a low-speed power output, preferably applied to e-bikes. It also discloses a bi- cycloidal power-split hybrid powertrain with proportional electric assistance to human pedaling power without using any torque sensor, which applies to both mid-motor and hub-motor e-bikes. And a third object of the present invention reveals a high-performance electrically assisted powertrain with an electric continuously variable transmission (e-CVT) for e-bikes, combining power-split and parallel hybrid drives, optimized by using the bi-cycloidal gear technology."
The patent application was internationally filed on Feb. 17, 2023, under International application No.PCT/IB2023/051477.
