Definitions

  • the present invention relates to a marine hybrid drive unit comprising a transmission with a modulatable transmission clutch and to a method to drive such a marine hybrid drive unit.
  • a typical conventional marine propulsion system comprises one or two drive trains, each with a diesel engine and a transmission with speed reduction gear steps interposed between the engine and the propeller.
  • This type of propulsion in which the propeller characteristics and a certain reduction ratio between the engine and the propeller are preset at the design stage, often includes a modulatable transmission clutch for operating at lower speeds than a nominal speed.
  • a marine hybrid drive unit with a transmission comprising a transmission input shaft for accepting power into the transmission and a transmission output shaft for outputting power to a propeller.
  • a first prime mover is selectively coupled to the transmission input shaft, whereas a second prime mover is permanently coupled to the transmission input shaft.
  • a modulatable clutch assembly is operably coupled to the transmission input and output shafts such that the power and speed from the input shaft can be variably transferred to the output shaft.
  • the purpose of the present invention is to provide an improved marine hybrid drive unit with a modulatable clutch, which allows optimized cruising conditions especially in a trolling mode with a simple structural design.
  • the present invention provides a marine hybrid drive unit comprising a drive shaft which is connected to a combustion engine, an electric motor and a transmission with an input shaft and an output shaft.
  • the input shaft of the transmission can selectively be driven solely by the combustion engine, solely by the electric motor or by the combustion engine and the electric motor simultaneously.
  • the transmission further includes a modulatable transmission clutch to selectively connect the input shaft to the output shaft.
  • a modulatable transmission clutch allows for a continuous adjustment of the difference between the rotational speeds of the input shaft and the output shaft.
  • the modulatable transmission clutch can be a pressure actuated hydraulic clutch, preferably in form of a multi-disk-clutch.
  • the transmission further comprises an oil pump, which is driven by the input shaft. The oil pump providing the oil pressure for the actuation of the modulatable transmission clutch. Therefore the pressure side of the oil pump is connected to a pressure chamber of the modulatable transmission clutch. At least one pressure control valve can be arranged to modulate the oil pressure in the pressure chamber accordingly.
  • Said input shaft is permanently connected to the electric motor via at least one gear step.
  • the gear step may comprise several spur gears which are configured to provide an appropriate gear ratio between the electric motor and the input shaft.
  • a suitable gear ratio of the at least one gear step can be set to drive the input shaft and the oil pump in all operating modes with an appropriate speed to provide sufficient oil for the actuation of the modulatable transmission clutch.
  • the oil pump In order to supply sufficient oil pressure and oil volume to the modulatable transmission clutch, especially in a trolling mode, the oil pump needs to be driven with a certain minimum speed. Therefore, it is essential, that the gear ratio is set to a value, which ensures said minimum speed at the pump while the electric motor can be operated as long as required in a technically feasible speed range. Otherwise the marine hybrid drive unit would need a second oil pump for the actuation of the modulatable transmission clutch in the trolling mode.
  • a certain minimum rotation speed of the input shaft is necessary to ensure that a sufficient oil pressure for the modulation of the modulatable transmission clutch is built up by the oil pump, which is driven by the input shaft.
  • a minimum rotation speed of around 500-600 rpm is required at the input shaft.
  • the gear ratio must be adjusted to a minimum operation speed of the electric motor to enable such operation mode.
  • the electric motor in this embodiment can be driven with a minimum operation speed in the range between 1250 rpm and 1500 rpm.
  • the gear steps are designed to provide a transmission ratio preferably in the range between 2 and 3. Such a transmission ratio has proven to be sufficient to provide for the minimum speed at the input shaft and the minimum oil pressure in all operating modes.
  • the proposed transmission ratio between 2 and 3 has proven to deliver an optimum range in view of the efficiency of the electric motor in the electric propulsion mode and in a recharge mode.
  • the electric motor can be used as a generator to recharge the batteries, while the input shaft is driven by the combustion engine.
  • a pressure actuated input clutch provided to connect and disconnect the drive shaft to the input shaft.
  • the oil pump is arranged to provide oil for the actuation of the pressure actuated input clutch, as well as for the modulatable transmission clutch.
  • the input clutch and the electric motor can be arranged inside a module housing of a hybrid module which is mounted in between the combustion engine and the transmission.
  • the transmission may comprise an oil lubrication system and said oil pump can be configured to supply oil to the oil lubrication system, as well.
  • a correct lubrication in terms of oil flow rate and pressure can be achieved in such an oil lubrication system to ensure a continuous and reliable cooling and lubrication of the components in the transmission and in the hybrid module.
  • there can be a separate low-pressure section for the oil lubrication system while the oil supply to the pressure actuated input clutch and the modulatable transmission clutch is provided by a high-pressure sections. Oil can be supplied to the low-pressure section and the high-pressure section by only one oil pump.
  • the full functionality of the marine hybrid drive can be achieved with only one oil pump.
  • the oil pump is an integral component of the transmission. No additional oil pump is required for one of said functions.
  • Another aspect of the invention is a method for driving such a marine hybrid drive unit in a trolling mode when the hybrid drive unit is driven solely by the electric motor.
  • the oil pump provides the oil pressure for the actuation of the modulatable transmission clutch, and wherein the speed of the output shaft is continuously adjustable by means of the modulatable transmission clutch in a range between 50% and 25% of the speed of the input shaft.
  • a speed reduction ratio in the lower section of said range allows to drive the boat with low and very low speed.
  • Such low speed can be required for docking maneuvers and in so-called no wake zones.
  • a no-wake zone is a section of a waterway with a strict speed limit.
  • state and/or local regulations When navigating through a no-wake zone, state and/or local regulations generally require that the captain observe the slowest-possible vessel speed to maintain steerage. There might be a certain speed limit of a maximum speed of 5 miles per hour, per example. The goal is to minimize the wake created by boats passing through the zone.
  • the proposed marine hybrid drive unit and the method allow to operate a boat in the full range of operating modes and speeds without the need of an additional oil pump for the actuation of one of the pressure actuated clutches.
