Abstract
A parallel or redundant hybrid drive of a marine drivetrain of a propulsion unit includes an input shaft, which is configured to be driven by a primary drive source; a clutch unit attached to the input shaft with which rotation of the input shaft can be either connected, reversed, or disconnected; a countershaft transverse to the input shaft and driven by the input shaft via a gear; and a secondary drive source arranged via an interconnected clutch at an end of the countershaft, so that upon driving of the input shaft by the primary drive source, the secondary drive source drives the countershaft either on its own or in cooperation with the primary drive source.
Claims18
A parallel or redundant marine drive train for a propulsion unit, comprising:
- an input shaft configured to be driven by a primary drive source;
- a clutch unit coupled to the input shaft, wherein the clutch unit selectively connects, reverses, or disconnects rotation of the input shaft, wherein the clutch unit is configured, in conjunction with a shift between forward and reverse positions, momentarily to brake the rotation;
- an output shaft transverse to the input shaft and driven by the input shaft via a gear;
- and
- a secondary drive source arranged via a clutch at one end of the output shaft such that, depending on whether the input shaft is driven or not, the secondary drive source runs either on its own or in cooperation with the primary drive source.
