Abstract
The invention discloses a power regeneration type braking and boosting integrated device used for a locomotive. The kinetic energy of the locomotive is recycled by virtue of a gear set, and the recycled kinetic energy of the locomotive is converted into air potential energy to be stored by virtue of a double screw air compressor. When the compressed air reaches a certain pressure, a generated counter acting force inhibits the action of the double screw air compressor, and finally the locomotive brakes. When the locomotive starts, the compressed air is released and expands to do work and then drive a high pressure air engine, thus the locomotive is driven. The dead weight of the device in the invention can be controlled in a lighter range, and the braking is safe and stable when a friction type braking is combined; and the energy recycling efficiency is high, the application range is wide, and the device can be applied to multiple locomotives and other traffic tools.
