Abstract: An epicyclic transmission gear and disk brake based regenerative braking device includes an epicyclic transmission unit to transfer braking energy through arrangement of sun gear and the planetary gears to a clock spring of a clock spring torque storage module. The device includes a disk brake unit that arrests the rotation of a sun-planetary gear assembly in the epicyclic transmission unit such that momentum available at the extended hub is transferred to a ring gear. The ring gear is connected to an inner casing of the clock spring torque storage module that charges the spring. The device includes a chassis unit that dissipates excess energy through spinning of an outer casing of the clock spring torque storage module by a spring calibration wheel that rides over a sinusoidal contoured surface of the outer casing.

Abstract: The present disclosure relates to the field of stroke-controlling mechanism, and discloses a stroke-limiting control assembly and an operating method. The stroke-limiting control assembly comprises a housing and a film winding. A transmission input gear, a transmission gear, a guide wheel, and a spring box that can be rotated to reset by an elastic force are rotatably connected within the housing. When a moving component moves to an end of an upper stroke, a first metal needle abuts a first proximity switch. When the movable component moves to an end of a lower stroke, a second metal needle abuts against a second proximity switch. At least a stroke-limiting control assembly is provided which enables simplification of a product requiring stroke-limiting, such as an electric jack or an electric support leg, by arranging the proximity switches outside a screw nut lifting unit in the electric jack or the electric support leg.

Abstract: A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear, a freewheel coupled to the idler gear, a locking mechanism for releasably locking the charging gear in a charged state of the stored-energy spring, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state of the stored-energy spring. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring disposed between the clutch blocks and is non-rotatably coupled to the first clutch block, the synchronizer ring is pressed against the second clutch block when the dog clutch is closed.

Abstract: The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. The mechanical energy may be converted to electrical energy at the same time as the valve actuator is operating or the mechanical energy may be stored for later conversion. A valve actuator may be operated manually, electrically, pneumatically, or hydraulically. Generated electrical energy may also be stored.

Abstract: A system for efficiently capturing the kinetic and/or potential energy of a moving vehicle includes an arc roller configured to move along an arcuate path upon impact by the moving vehicle, and a torsional spring configured to wind in response to the movement of the speed bump and, thereby, to store energy associated with the impact. The torsional spring may be configured to wind continually in response to the movement of another speed bump and, thereby, to store additional energy associated with the impact of the vehicle with the other speed bump. The system may include alternators or generators producing electricity from energy released from unwinding of the torsional spring. Electricity is further stored and utilized for onboard computing, traffic analytics, safety feature operating functions and communications.

Abstract: There is provided a spring-powered drive apparatus including a casing (102), an output shaft (103) mounted on the casing (102) in a relatively rotatable manner, a one way clutch (112) externally fitted on the output shaft (103) in the casing (102) and, a spiral spring (105, 107) housed in the casing and wound by turning of the output shaft (103) in the direction in which the one way clutch (112) transmits torque. Thus, there can be provided a compact spring-powered drive apparatus and a self-propelled caster that can be applied to a work cart or the like.

Abstract: In at least one implementation, a torsion rod preload device, includes a body, a driver and a retainer. The body may have a base adapted to be connected to a vehicle and at least one stop. The driver is carried by the body for movement relative to the body, and is adapted to engage a torsion rod so that movement of the driver relative to the body increases a torsion force within the torsion rod. The retainer is carried by one or both of the body and the driver, and is movable by the driver as the driver moves relative to the body. The retainer is engageable with the stop to inhibit or prevent movement of the driver when the retainer is engaged with the stop to maintain a desired torsion force in the torsion rod.

Abstract: Described is a spring mechanism. The spring mechanism includes a leaf spring housing with leaf springs radially disposed within the leaf spring housing. The leaf springs being flexible between a rest state and tension state. A winding mechanism is engaged with the leaf springs for causing the leaf springs to flex from the rest state to the tension state. The winding mechanism includes a pushing pin wheel with a plurality of pushing pins protruding therefrom that rest against the leaf springs. The pushing pin wheel is rotatable such that rotation of the pushing pin wheel causes the leaf springs to flex from the rest state to a tension state Release of the tension (i.e., when the leaf springs return to the rest state from the tension state) causes rotation of the leaf spring housing which causes rotation of a corresponding release gear set and output drive.
