Abstract:
Предложен гибридный силовой агрегат транспортного колесного средства, включающий первичный источник энергии, двигатель внутреннего сгорания, накопитель энергии и привод, выполненный с возможностью изменения числа оборотов вращения и передающий вращение на привод ведущих колес транспортного средства. Двигатель внутреннего сгорания содержит декомпрессор и выполнен с возможностью работы на двух режимах: нагрузочный режим с выключенным декомпрессором и режим маховика, в виде вращающихся деталей двигателя, с включенным декомпрессором. В накопителе энергии используется, по крайней мере, один супермаховик, маховик в виде вращающихся деталей двигателя и электрохимический аккумулятор. Изобретение позволяет уменьшить расход топлива и улучшить экологические показатели путем перевода режима работы двигателя из нагрузочного в режим маховика без использования холостого хода.
Abstract:
Vehicles of embodiments of the invention are propelled by an electric motor (DC or AC motor) coupled to one of the vehicle's axles. The electric motor is powered by two or more electrical storage devices (e.g., batteries or battery banks or capacitors). The electrical storage devices are charged by alternators driven by a rotating flywheel. The flywheel is selectively coupled to a different one of the vehicle axles, such that movement of the vehicle (caused by the electric motor) causes the rotation of the flywheel.

A system for storing and recovering energy associated with a machine having ground engaging tracks is disclosed. The system includes a power source configured to supply mechanical energy for operation of the machine, and an electric generator operably coupled to the power source. The electric generator is configured to convert at least a portion of the mechanical energy into electric energy. The system further includes an electric motor operably coupled to the electric generator. The electric motor is configured to supply power to the ground engaging tracks. The system includes an energy storage device configured to store energy associated with the machine, and a controller configured to divert a portion of the energy supplied by the power source to the energy storage device while the machine travels in a first direction, and recover energy stored in the energy storage device for use while the machine travels in a second direction.
Abstract:
A system and method for generating power includes a motor assembly, an inertia-assisted, torque-enhanced gearbox, including a flywheel assembly and a clutch assembly, and a generator assembly. The motor assembly is used to drive the flywheel assembly up to the generator's designed operating speed. When the flywheel assembly reaches the generator operating speed, the clutch assembly engages and connects the flywheel assembly to the generator assembly. When the flywheel assembly is connected to the generator assembly, it supplies the generator with the starting torque required to start the generator. The motor assembly then supplies the torque necessary to operate the flywheel assembly and the generator assembly at the generator's designed operating speed. When the generator encounters peak loads, the flywheel assembly also supplies peak load torques to the generator assembly. The generator assembly is operable to supply power to a load connected to the generator assembly.

Abstract:
A flywheel support system isolates the flywheel (11) and its motor-generator (21) from the driving environment of an electrically powered motor vehicle. A suitable liquid (9), placed between the outer (8) and vacuum (10) housings of the flywheel assembly, provides buoyancy and damping to the vacuum housing, cooling the motor-generator, and serves as one of the barriers to rotor energy and angular momentum transfer in the event of and accident or failure. During normal operation, a shearable mechanical gimbal system (80) keeps the vacuum housing centered in the outer housing, reacts the spin moments generated by the motor-generator, and provides a path for the electrical leads into the vacuum housing. In the event of bearing seizure or rotor failure, the mechanical gimbal will shear and allow the vacuum housing to gradually spin down against the fluid. A system of angular-contact oil-lubricated ball bearings (12, 13) supports the rotating assembly including the rotor (21b) of the motor-generator. A squeeze film damper (145) associated with the lowermost bearing (13) minimizes mechanical vibrations. A molecular drag pump (26) maintains a high vacuum for the rotating assembly. The placement of the center of gravity of the vacuum housing and its contents below the center of buoyancy produces a vertical orientation of the vacuum housing in the absence of accelerations, allowing the offloading of the flywheel rotor weight by a magnet (23).
Abstract:
The drive system for a motor vehicle comprises an internal combustion engine (1) with at least one controlling element (29) affecting its power and/or torque and/or rotation speed, controllable by a motor element (27), an electric generator system (3) driven by the engine (1), at least one electric motor (11) powered by the generator system (3) and driving the motor vehicle and an electronic control (19) which controls at least the one motor element (27) and the electric power supplied by the generator system (3) and/or the electric power taken by the electric motor (11) depending on the position of an accelerator pedal (23). The system includes means for detecting the actual value of the rotation speed of the engine (1) and means for detecting an actual value of the power supplied by the generator system (3). The control (19) comprises rotation speed regulators (33), which maintain the actual rotation speed at a predetermined setting, and power regulators (37) which maintain the actual electric power at a predetermined setting. To the control (19) is allocated a data store (31) in which characteristic data for combinations of data for the power setting and data for the rotation speed setting and/or data for regulating the at least one motor element (27) are stored. Both with the generator arrangement (3) and with the engine (1) on overrun, depending on the current from the generator arrangement, the control (19) detects the torque cycle depending on the crankshaft angle and, depending on the rotation speed cycle, diagnoses operating faults and/or the state of the motor.
