Definitions

  • Generator-motor used for electric power supply, starting the internal combustion engine and prime mover propulsion
  • the presented invention relates to the device for generating direct and or alternating current starting the internal combustion engine and or propulsion of the mobile unit particularly boat, ship, yacht, sailboat, ship crane, agricultural machinery, excavator etc. with a maintenance free generator-motor unit, combined with an internal combustion engine, a clutch unit and a transmission.
  • a maintenance free generator-motor unit combined with an internal combustion engine, a clutch unit and a transmission.
  • this invention it is possible to drive a mobile unit with internal combustion engine or electrically through the simple generator-motor, fed by batteries through DC-AC converter in both directions. It is also possible to generate electric DC and or AC power by the same generator-motor driven by internal combustion engine and added electric-electronic components.
  • the mobile unit is equipped with a maintenance free high frequency generator-motor, integrated in the flywheel housing of the internal combustion engine.
  • the flywheel housing is protected by gaskets and watertight cable connection to avoid water entrance to the electric generator motor and its windings, when the water enters the floating mobile unit.
  • the generator-motor is equipped with permanent magnet rotor poles with a high number of poles to enable high generator frequency and high motor torque from a relatively small unit.
  • the rotor poles are preferably made from rare earth permanent magnets. With a high generator- motor frequency, sufficient electric generator power is available at a low engine speed, enabling full electric power generation with low noise and low pollution burden, when the internal combustion engine does not drive the mobile unit with high power output.
  • the generator-motor windings are connected to the DC-AC converter to operate the generator-motor as the engine starter. In this case the clutch connecting crankshaft prolonging shaft with the generator-motor rotor is engaged.
  • the DC-AC converter is controlled by the remote control, placed at the mobile unit operator panel. An automatic starting of the internal combustion engine is also possible when the battery voltage is too low. For a mobile unit electric drive, the clutch connecting internal combustion engine with the generator-motor rotor is disengaged, and.
  • the generator- motor windings are connected and controlled in the same way.
  • the generator-motor windings are also connected to the AC-DC rectifier to supply the DC voltage to the DC- DC converter over DC filter for regulating the generated DC voltage, charging the batteries and feeding the DC-AC inverter for constant voltage and frequency AC mobile unit supply.

Description

Generator-motor used for electric power supply, starting the internal combustion engine and prime mover propulsion
BACKGROUND OF THE INVENTION
The presented invention relates to the device for generating direct and or alternating current starting the internal combustion engine and or propulsion of the mobile unit particularly boat, ship, yacht, sailboat, ship crane, agricultural machinery, excavator etc. with a maintenance free generator-motor unit, combined with an internal combustion engine, a clutch unit and a transmission. With this invention it is possible to drive a mobile unit with internal combustion engine or electrically through the simple generator-motor, fed by batteries through DC-AC converter in both directions. It is also possible to generate electric DC and or AC power by the same generator-motor driven by internal combustion engine and added electric-electronic components.
SUMMARY OF THE INVENTION
According to the presented invention, the mobile unit is equipped with a maintenance free high frequency generator-motor, integrated in the flywheel housing of the internal combustion engine. The flywheel housing is protected by gaskets and watertight cable connection to avoid water entrance to the electric generator motor and its windings, when the water enters the floating mobile unit. With the integration of the electric generator-motor in the flywheel housing it is possible to use this device in a simple way for generating electric current, when connected to the internal combustion running engine and for operating the prime mover in both directions, when connected to the transmission and supplied with adequate AG electric power, voltage and frequency from the DC-AC converter, connected to the battery. The generator-motor is equipped with permanent magnet rotor poles with a high number of poles to enable high generator frequency and high motor torque from a relatively small unit. The rotor poles are preferably made from rare earth permanent magnets. With a high generator- motor frequency, sufficient electric generator power is available at a low engine speed, enabling full electric power generation with low noise and low pollution burden, when the internal combustion engine does not drive the mobile unit with high power output. The generator-motor windings are connected to the DC-AC converter to operate the generator-motor as the engine starter. In this case the clutch connecting crankshaft prolonging shaft with the generator-motor rotor is engaged. The DC-AC converter is controlled by the remote control, placed at the mobile unit operator panel. An automatic starting of the internal combustion engine is also possible when the battery voltage is too low. For a mobile unit electric drive, the clutch connecting internal combustion engine with the generator-motor rotor is disengaged, and. the generator- motor windings are connected and controlled in the same way. The generator-motor windings are also connected to the AC-DC rectifier to supply the DC voltage to the DC- DC converter over DC filter for regulating the generated DC voltage, charging the batteries and feeding the DC-AC inverter for constant voltage and frequency AC mobile unit supply. With this system there is no need for an internal combustion engine belt driven alternator and a beltless internal combustion engine is possible, reducing maintenance costs and improving reliability. For a raw water pump, when needed, an electric motor is foreseen, preferably a thermostatically speed controlled version. A separate electric starter motor is also not needed reducing the cost dimensions and weight of the equipment. The flywheel does not need teeth for starter engagement, and can be easily used also as the second torsion damper by adding damping material and the second ring. (This feature is not shown on the Figures)
THE FOLLOWING EXAMPLES ARE MADE AS PRIOR ART OF INVENTED SOLUTION
The patent SI 21586 describes a combination of an internal combustion engine with a maintenance free generator, integrated in the flywheel housing and connected to an electronic device, to transfer the three phase AC current with variable voltage to the constant voltage AC and DC outputs. The provision is made to use the generator as the engine starter. With this solution the generator is connected to the flywheel and crankshaft. No provision however is made to operate the mobile unit with the same generator. There is no clutch available to separate the generator from the internal combustion engine. The operation of the mobile unit, only by a generator is not possible. The beltless version of the internal combustion engine and an electric motor for the raw water pump are not foreseen. ;
The patent US 5,214,358 describes the invention with the generator connected to the internal combustion engine flywheel, with additional electronic control units, to charge the battery and provide the electric propulsion motor with desirable AC voltage. However with this solution a direct mechanical operation of mobile unit is not possible. There are at least two electric machines required to operate the vehicle. This results in a higher weight, higher cost and higher maintenance requirements.
The patent EP 1415837 A describes a parallel configuration system for hybrid propulsion of wheel driven vehicles. The drive thrust is distributed between an electric engine and an internal combustion engine through a transmission system delivering simultaneously the torque of both engines to the vehicle wheels. The internal combustion engine is operating at a steady state. There is no provision done to supply the vehicle with the constant voltage AC electric current. The invention does not foresee DC electric supply when the internal combustion engine is not in operation. There is no provision to eliminate the alternator driving belt.
The Patent DE 29604437 U relates to a hybrid propulsion system for ships, which comprises a main diesel engine combined with an electric motor to reduce the specific fuel consumption. There is no provision to deliver constant voltage DC and AC current to the mobile unit. The invented solution shows no possibility to operate the ship only by an electric motor. The possibility to start the internal combustion engine by the electric motor is not foreseen. The separation of the crankshaft from the electric motor is not available.
The patent FR 2814121 relates to the hybrid propulsion, consisting of the internal combustion engine, clutch connecting the electric motor, additional clutch' connecting the electric motor to the gearbox. There is no provision to supply constant voltage DC and AC current to the vehicle. There is no provision for a beltless internal combustion Engine. There is no electric pump foreseen for raw water pumping, because the road vehicles do not need them. There is no torsion damper foreseen to damp the clutch engagement.
PURPOSE OF THE INVENTION :
With the presented innovative solution, it is possible to use only one simple electric machine, in this case a maintenance free generator-motor with no windings in the rotating components, to produce DC constant voltage and AC constant voltage and frequency electric current for not propulsion requirements of the mobile unit. With the solution the electric power is available at all engine speeds At the same time the mentioned generator-motor is able to start the internal combustion engine of the mobile unit. The same generator-motor unit is used to operate electrically the mobile unit according the capacity of the batteries. This saves the cost of the equipment, cost of installation, maintenance cost and the weight of the equipment. All that in comparison to all known invented or marketed solutions. With the watertight installation of the generator-motor in the hermetically closed flywheel housing, highest reliability is possible for the mobile units, exposed to the partial water over floating or splash water. With the capability to produce AC constant voltage and frequency electric current through the DC-AC inverter, the AC electric current is available also, when the only electric machine is not operating, by using the spare battery capacity. It is only necessary to run the internal combustion engine part time with the reduced engine speed when only a part of the maximum electric power is required.
DESCRIPTION OF THE DRAWINGS
Referring to the Fig 1 , the flywheel housing 11 connected watertight with a liquid or sheet gasket to the internal combustion engine, 1 a stator 2 of the generator- motor is integrated and fixed. The stator 2 is made from the laminated metal sheets made from the magnetically highly conductive steel alloy. Multi pole three phase windings 12 are integrated in the stator and connected through a watertight isolating connection 35 to the AC-DC rectifier 17 and DC-AC converter 16. With the remote control 30, the frequency and the voltage of the output of DC-AC converter 16 are controlled to start the engine 1. The electric current for DC-AC converter 16 is supplied from battery. 20 For frequency control an engine 1 speed input is desirable. This speed input is available from the engine controller. When starting the engine 1 the transmission 9 should be in neutral position. The clutch 29 is engaged and connects the crankshaft or crankshaft connecting shaft 15 with the generator-motor rotor. 3 The DC-AC rectifier 17 is connected to the DC filter 18 to avoid to high frequency disturbances from the added DC-DC converter-voltage regulator 19 to enter generator-stator windings 12 and cause temperature increase of the generator-motor. The DC-DC converter-voltage regulator 19 supplies the required DC voltage to the system output, batteries 20 and DC-AC inverter 31. The output of the DC-DC converter 19 is controlled adequate to the battery voltage, charge status and according to the battery charging characteristics. With remote inverter control, the inverter can be switched on or of from the remote place used primarily by operator. The rotor 3 is mad by magnetic conductive material and equipped with permanent magnets 26. The permanent magnets from rare earth enable higher generator-motor power output. The rotor is free rotationally mounted to bearings 22 and 41 , preferably ball or roller bearings. (In Fig. 2 bearing 39) The bearings 22 and 41 are placed on the crankshaft or crankshaft connecting shaft 15, and enable free rotation of the rotor 3 on the stationary crankshaft prolonging shaft 15 when the internal combustion engine 1 is not operating. When the clutch 29 is not engaged with the dog clutch elements 6 and only clutch elements 28 are engaged, the rotor 3 is connected with the transmission inlet shaft 8 and the mobile unit can be operated by generator-motor, feed by DC-AC converter 16 in both rotational directions, driving the propeller through the transmission with preferably reduced speed of the electric motor 2. The clutch 29 is continuously connected to the transmission input shaft 8 by dovetailing gear and with the generator-motor rotor with the clutch elements 28. A bearing 37, preferably roller bearing type 38 is used for better alignment of the crankshaft 14 or crankshaft prolonging shaft 15 with the transmission input shaft 8. With the clutch fork 27 the clutch 29 is engaged or disengaged. With the cooling channels 42, the generator-motor 2 is cooled sufficiently to enable high output with a waterproof unit. At the same time the rare earth rotor 3 permanent magnets 26 are protected from too high temperature, which could demagnetize them. The radial gaskets 7, 43 and 44 prevent the lubricant from entering generator-motor not lubricated area. The clutch fork can be engaged and disengaged by a remote controlled 33 electric actuator 34 as presented with Fig. 3.
Fig 2 shows the same device, with added torsion clutch damper integrated in the rotor 25 with damping material 23 and damping shaft 24. The damping shaft is continuously engaged with the clutch elements 28 to the clutch 29. The rotational angle limiter limits the maximal angular deformation of the torsion clutch damper and guaranties full operation of the system when the damping material 23 is damaged. The torsion damper has advantages for the transmission systems with rapid torque changes or torque kicks.
Fig 3 shoves the remote control 33 of the of the clutch fork 27 by electric actuator 34. With this equipment the mobile unit operator can engage and disengage the clutch 29 from the drivers place.
