Power transmission apparatus for industrial and transportation applications for e.g. regenerative traction drive for electrified railway

摘要

The apparatus includes a power transmitting device (110) and a transmission interacting mechanism (120) which are integrated together and manipulated to provide mechanical and/or electrical power. In an electromagnetic implementation, a rotary commutator and an electromagnetic device respectively replaces the elements (110,120) and is capable of handling more than one of the four modes of power transmission. In general, the power transmitting device comprises at least two power interaction elements (111,112), in which a first element transmit power to a second for implementing its interaction of power transmission. The power transmitted in the power transmitting device received from an external power source (181) via an input (131), is then redistributed by the transmission interaction redistributing mechanism onto an output (132) and delivered to an external load (182). When the power received by the apparatus is an electrical power, the input is an electrical lead that can be electrically connected to the external power source. In this case the external power source generates an electrical power and the input coupling (171) is an electrical coupling. At the output end, when the power delivered is an electrical power, the output is an electrical lead that can be electrically connected to the electrical load which consumes electrical power and the output coupling (172) is an electrical coupling. Independent claims are also included for the following: (1) mechanical implementation of the apparatus and (2) electromagnetic implementation of the apparatus.
