摘要:
A mobile mining machine includes a plurality of traction elements, a plurality of motors, a power source in electrical communication with the plurality of motors, and an energy storage system in electrical communication with the plurality of motors and the power source. Each of the motors is coupled to an associated one of the plurality of traction elements. Each of the motors is driven by the associated traction element in a first mode, and drives the associated traction element in a second mode. The energy storage system includes a shaft, a rotor secured to the shaft, a stator extending around the rotor, and a flywheel coupled to the shaft for rotation therewith. In the first mode, rotation of the motors causes rotation of the flywheel to store kinetic energy. In the second mode, rotation of the rotor and the flywheel discharges kinetic energy to drive the motors.

A digitally controlled motor device with storage (1) comprises a stator and a flywheel (10) having an axis of rotation and being rotatably mountable on a shaft (60) of a rotating machine and having at least a first set of magnetic coils (13) arranged thereon; an induction rotor (20) having an axis of rotation and being mountable on the shaft in magnetic communication with the first set of magnetic coils of the flywheel such that a change in magnetic flux at the first set of magnetic coils induces a current in the induction rotor. At least one set of second magnetic coils (12) is arranged on the stator in magnetic communication with the induction rotor (20). A controller (30) controls a supply of electrical power from the flywheel (10) to the second set of magnetic coils (12) to force acceleration or deceleration of the induction rotor (20), whereby the induction rotor (20) is adapted to receive electrical power from the flywheel (10) via the first set of magnetic coils (13) and from the second set of magnetic coils (12).

A hybrid vehicle includes at least one axle, an energy storage device disposed within the hybrid vehicle, a fuel consuming engine, a power boosting feature, and a controller. The fuel consuming engine is operably connected to selectively provide power to at least one of the energy storage device and the at least one axle. The engine is capable of providing at least the mean but less than a peak power to drive the hybrid vehicle over a typical route. The power boosting feature is configured to provide the fuel consuming engine with additional power to achieve a desired power to accelerate the hybrid vehicle. The controller is adapted to selectively control power flow to the one or more axles from one or more of the energy storage device, the engine, and the power boosting feature to achieve the desired power.

A vehicle driveline and a method for transferring energy from a flywheel is provided. The vehicle driveline includes a power source (204), a clutch (206)drivingly engaged with the power source, a transmission (208) drivingly engaged with the clutch, a power transmission device (220) drivingly engaged with one of the power source, the clutch, and the transmission, a controller (224) in communication with the power transmission device, and a flywheel (202) drivingly engaged with the power transmission device. The power transmission device facilitates a transfer of energy from the flywheel to one of the clutch and the transmission. The power transmission device also facilitates a transfer of energy from one of the power source, the clutch, and the transmission to the flywheel. The controller directs the transfer of energy to and from the flywheel.

A flywheel module 5.1 comprises a flywheel F as well as a speed transforming device I 1 which has a first in/output Ii which is connected to the flywheel F, and a second in/output I 2 which is coupled to a drive line of a vehicle 11. The speed transforming device I has a bypass speed transforming device P and a motor and/or generator MG. Energy can then be exchanged with the flywheel F by suitably controlling the motor and/or generator MG. As a result of the delivery of a negative torque by the motor and/or generator, the flywheel F accelerates and because of the delivery of a positive torque by the motor and/or generator the flywheel decelerates.

The power transmission system for use in a vehicle includes a power split device (24) to perform power distribution among a flywheel (30) for storing rotational energy as mechanical energy, an internal combustion engine (10) and an electric rotating machine (32). The power transmission system is provided with an interrupting device (20) configured to interrupt power transmission between a group of the flywheel (30) and the electric rotating machine (32) and a group of the internal combustion engine (10) and drive wheels (16) of the vehicle when rotational energy stored in the flywheel (30) is transmitted to the electric rotating machine (32) through the power split device (24) under condition that power is transmitted between the internal combustion engine (10) and the drive wheels (16). A further embodiment (Figure 8A) is disclosed showing two power split devices (54,58) as well as two motor-generators (50a,50b).
