Embodiment Construction
[0067] Certain embodiments of the invention relate to an omnidirectional propulsion system including a shock absorption system. The damping system is designed to absorb heat generated during steering system over-torque situations of the propulsion system. Such an over-torque situation may occur, for example, when at least a portion of the propulsion system is exposed to a collision with a block of ice or any other object. The system is able to absorb this shock and absorb the heat generated by allowing the propulsion unit to rotate with the colliding object in the proper direction.
[0068] exist figure 1 In , a schematic diagram of an omnidirectional propulsion system 1 according to at least some embodiments of the present invention is illustrated. The propulsion system 1 comprises equipment for generating propulsion power for the propeller shaft and transmissions located outside the hull 12 of the vessel within a special propulsion unit 3 supported for rotation relative to...
