Transmission system

A transmission system, comprising:

• a planetary gear assembly comprising the following gear elements
• i a planet carrier;
• ii at least one planet gear mounted on said planet carrier;
• and at least one of:
• iii a sun gear;
• or
• iv a ring gear;
• a first-side mechanism comprising a chamber and a first-side shaft having
• a connection end connected to the chamber, and a free end;
• at least one transfer arrangement, comprising a transfer mechanism and a transfer shaft having a first end connected to the transfer mechanism;
• and
• a second-side mechanism comprising a second-side shaft;
• wherein the chamber is fluidly coupled to the transfer mechanism for transfer of rotary motion therebetween, and wherein
• the chamber is connected to one of the gear elements (i), (iii), or (iv);
• the transfer shaft is connected to one of the gear elements (i), (ii), (iii), or (iv);
• and
• the second-side shaft is connected to one of the gear elements (i), (iii), or (iv);
• such that each of the gear elements is only coupled to one of the chamber, said transfer shaft, or the second-side shaft throughout the operation of the transmission system, and wherein the planetary gear assembly includes a multi-level planetary gear assembly comprising more than one of the following gear elements:
• the planet carrier (i), the at least one planet gear mounted on the planet carrier (ii), the sun gear (iii), or the ring gear (iv).
