Abstract:
A device for maintaining and transmission of a rider's energy to a drive wheel while pedalling, which is pivoted on a shaft that is stiffly fastened between rear fork of the wheel bracket, wherein a wheel rim is arranged on the device of the invention in a known way, said rim being intended for installation of a tyre with a tube in optional mutual construction. The device comprises a tubular housing (1), in which a coil spring (2) is arranged, wherein the housing (1) is closed at one end with a part (4), whereas its other end is intended to receive a known sprocket-wheel. Free ends of the spring (2) lean against two teeth (3) in the housing (1) or rather part (4), so that the spring (2) is fixed in direction of unscrewing, when angular rotation appears between the housing (1) and the part (4). A central part (5) of the internal surface of the housing (1) has a larger diameter, which makes it possible for the central part of the spring (2) - at said mutual angular rotation of the housing (1) and the part (4) - to rotate for an increasing diameter on its central part by that much as allowed by the larger diameter of the central part (5).
Abstract:
A regenerative braking system (50) for a cycle rickshaw (100) is provided herein. The regenerative braking system (50) includes a central hollow shaft (20) provided on a rickshaw main shaft (30). The regenerative braking system (50) further includes a handle section (24) located near main handle of the rickshaw. The regenerative braking system (50) further includes a gear section (25) having a first bevel gear (19), a second bevel gear (10), a third bevel gear (13), and a fourth bevel gear (15). The regenerative braking system (50) further includes a spring section (26) configured to store energy of the second bevel gear (10) in a spring (1), based on engagement of the first bevel gear (19) and the second bevel gear (10) during rotation of the central hollow shaft (20). The spring section (26) is further configured to release energy based on disengagement of the first bevel gear (19) and the second bevel gear (10) to effect the movement of the cycle rickshaw (100) in a forward direction.
Abstract:

Abstract:
The invention relates to renewable energy sources, in particular to the use of the potential energy of moving transportation means or pedestrians, waves, water, the energy of arms and legs of a human being, and to converting said energy into electrical or mechanical energy. In the first variant, the energy converter is in the form of a road power device with a spring-loaded platform. In another variant, the energy converter is in the form a wave power device with pontoons transmitting motion to vertical elements. In the next variant, the energy converter is in the form of a rocking arm device which is used for converting the potential energyof a liquid and is provided with alternately lifting reservoirs. In the subsequent variant, the energy converter is provided with blades, a platform and a bar. In the next variant, the energy converter is in the form of a bicycle with two additional freewheel clutches. In the next variant, the energy converter is in the form of a propelling device for an invalid carriage provided with alternatively interacting freewheel clutches. The invention makes it possible to simplify the structural design and to extend the functionalities of converters.
Abstract:
A wheeled transportation device (10) comprising: a steering assembly; a deck (16) for supporting a rider thereon; a rear wheel assembly comprising an arm member (18) pivotally mounted to the deck (16) and at least one wheel (26) mounted on said arm member; and an energy storage system mounted to the deck so as to engage with the arm member of the rear wheel assembly; wherein, the energy storage system is configured to store a potential energy therein when the rear wheel assembly pivots away from the deck, and to release the stored potential energy upon activation by the rider to return the rear wheel assembly to a neutral position thereby generating a lifting force in the deck to assist the rider to perform a jump manoeuvre.
Abstract:
L' invention concerne un dispositif de transport humain permettant de stocker une énergie fournie manuellement et d' en contrôler la délivrance pour réguler la vitesse de mouvement. Il est constitué d'un levier (1) permettant à l'utilisateur de fournir de l'énergie au système. Une chambre (6) dont le volume variable agit sur des ressorts de compression (11) contient un liquide dont le débit d'évacuation est contrôlé par une vanne (10). La détente des ressorts de compression (11) engendre le mouvement d'une crémaillère (8) transmis par un système d'engrenage (14) à la roue (16) du véhicule. Le dispositif selon l' invention est particulièrement destiné au stockage et à la restitution d'énergie destiné à la propulsion d'un engin de transport.
Abstract:
Le conducteur du véhicule actionne le pédalier (1) au moyen des pédales (20). Les cames (16) distribuées sur l’arbre à cames (17) font osciller les leviers à bascule (13) et les leviers d’armage (9), ce qui amène les ressorts (7) successivement dans leur position d’armage maximum. Durant le mouvement de retour, les paliers (11) solidaires des leviers d’armage (9) entraînent l’arbre moteur commun (10), ce qui fait tourner les roues (5) reliées à l’arbre (10) par l’intermédiaire d’un engrenage planétaire, d’un arbre moteur secondaire, et d’une transmission à chaîne ou poulie avec un changement de vitesse.
