A hydrodynamic lock-based CVT gearbox is disclosed. The apparatus is configured to continuously convert input rpm into different rpm's without interrupting a gearbox connection with an engine using a suspended and single-speed gearbox, and clockwise and counterclockwise rotation control of hydrodynamic lock. The apparatus is configured to utilize parallel paths pattern for power transfer, which includes a first power path and a second power path parallel to the first power path. The first power path is configured to reduce rotation and increase torque. The second power path is configured to provide equal rotation of the input and output axes. The apparatus is further configured to transfer the power from the first power path to the second power path by disposing a limiter at the first power path. At the end, the rotational force of the paths is combined and transmitted to the output of the gearbox.
