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.

The invention relates to a motor vehicle having three motors, i.e. an electric motor, hydraulic motor, and heat engine, and to a method for managing the energy stored onboard. The three motors (19, 25, 15) are particularly used for driving the vehicle, and are associated with means for storing electrical energy (21), hydraulic energy (28, 29), and fossil energy (18), respectively. The heat engine (15) is arranged so as to be connected in series and so as to recharge the means (28, 29) for storing hydraulic energy, but not the means (21) for storing electrical energy. During travel, the means (21) for storing electrical energy is not recharged by the heat engine (15) which can recharge the means (28, 29) for storing hydraulic energy of the hydraulic motor.

An installation structure of a one-way clutch (5) having an inner ring (5a) and an outer ring (5b) is provided. In order to prevent malfunction of the one-way clutch caused by a damage of a rivet (33), a first clearance (C1) between one face of a flywheel (4) and a top face of a head (34) of the rivet (33) is reduced to be narrower than a thickness (T1) of a stopper plate (32).

摘要:
In a shared processor control system for a power train of a hybrid electric vehicle operating responsive to operation of an accelerator pedal (7) and a brake pedal (8) and including a gas turbine (1b) powering a first motor-generator (1c), a flywheel (2b) powering a second motor-generator (2a), and a traction third motor-generator (3) operatively coupled for selectively driving and being driven by vehicle wheels (11), each of the first, the second and the third motor-generators being commonly connected to a high voltage bus (12) via respective rectifier-inverters (6) controlled by a single controller. The control system is operated by a method including steps for operating the accelerating pedal (7) to produce a substantially instantaneous increase in output torque with an increase in the bus (12) by the traction motor (3) to thereby produce a voltage drop, initiating increased power output from the flywheel motor-generator (2a) in response to the voltage drop to hold up the bus voltage, thereby decreasing flywheel shaft speed, and subsequently producing a proportional increase in the speed of the gas turbine (1b) in response to the decreasing shaft speed to thereby cause an increase flow of fuel to the gas turbine (1b) so as to permit an increase in voltage provided by the first motor-generator (1c). A method for providing compressive braking is also described.

摘要:
The present invention relates to a hybrid vehicle comprising an internal combustion engine; a transmission; at least one driving wheel rotationally connected to the transmission; a coupling arrangement arranged between the internal combustion engine and the transmission, and controllable between a first state in which the drive shaft of the internal combustion engine is rotationally connected to the transmission and a second state in which the drive shaft of the internal combustion engine is rotationally disconnected from the transmission. The hybrid vehicle further comprises an energy recovery device connected to the coupling arrangement via a flexible driving member for allowing recovery and storage of energy recovered from deceleration of the at least one driving wheel; a sensor for sensing a parameter value indicative of desired deceleration; and a control unit for controlling the coupling arrangement to the second state when the sensed parameter value indicates desired deceleration of the hybrid vehicle.
