An electromechanical flywheel machine includes a flywheel mass and a motor-generator having a rotor rotatable about a stationery inner stator having stator windings.

The present invention intends to provide a rotary tilling apparatus capable of separating a power transmission system starting from a flywheel to a passive movement device through an elastic coupler from another power transmission system starting from the flywheel to a rotor of a motor generator, and thereby reducing a load applied to the rotor and preventing the power transmission system of the passive movement device from providing an negative effect to an engine and the rotor. A parallel hybrid power transmission mechanism (1) includes an engine (2), a crank shaft (2A) disposed on the engine (2), a motor generator (3), a passive movement device (4) configured to receive a motive power of the motor generator (3), an input shaft (4A) disposed on the passive movement device (4), a flywheel (5) coupled to the crank shaft (2A), an elastic coupler (6) configured to couple the flywheel (5) to the input shaft (4A), and a rotor (7) disposed on the motor generator (3) and coupled to the fly wheel (5).

Aspects of the disclosure provide an electric actuator including a first driving source coupled to an output through a first pathway created by a transmission, a second driving source coupled to the output though a second pathway created by the transmission that, upon the electric actuator losses electrical power to the electric actuator, causes the output to be positioned at a fail-safe position, a differential coupled to the first driving source and the second driving source through a third pathway created by the transmission to store energy from the first driving source in the second driving source, and a switching controller that is configured to control switching the transmission between the first pathway, the second pathway, and the third pathway.

A gearbox includes a planetary gearset, an input shaft coupled to a sun gear of the planetary gearset, and an output shaft coupled to planet gears of the planetary gearset via a carrier. A constant torsion spring is coupled to a ring gear of the planetary gearset. The constant torsion spring is capable of preventing the ring gear from moving when a torque at the output shaft is below a threshold. The ring gear winds the constant torsion spring in response to the torque exceeding the threshold.

An apparatus comprising: a flywheel mounted on a flywheel shaft; a bearing arrangement on which the flywheel shaft is supported; a gearing arrangement for torque coupling the flywheel to a drive member; a sealing arrangement; and a housing for containing the flywheel, bearing and gearing arrangements, the gearing arrangement being arranged to be in torque transmitting engagement with the flywheel, via the flywheel shaft, and having an engagement means for being in torque transmitting engagement with the drive member, the sealing arrangement comprising a pair of seals, defining a cavity, and forming a hermetic seal, between the engagement means and the housing, whereby, in use, a first pressure is maintained within the housing that is lower than a second pressure outside of the housing, and the seals retain a fluid within the cavity, and maintain the fluid at an intermediate pressure between the first and the second pressure.

An apparatus to store and release potential energy. Two clutch bodies, radial ring, first and second crossbars, and first and second radial tees are disposed on an axle. Sets of radial spring tube assemblies are attached to both the first radial tee and the second radial tee, and the distal ends of the sets of radial spring tube assemblies are each attached to the radial ring. The radial spring tube assemblies store energy via springs when the axle is rotated and the first clutch body and the second clutch body are engaged, which in turn rotates the first radial tee and the second radial tee while the radial ring remains stationary. The first clutch body and the second clutch body disengage when a brake on the radial ring is released, thus allowing the stored potential energy in the radial spring tube assemblies to be released.
