Generator, especially for extracting brake energy in vehicles

摘要

A generator (20,30) for generating electrical energy, especially for extracting brake energy in vehicles, comprises two magnetic field-producing coils (1-32) lying opposite one another, separated by an airgap (29,45) to each of which is assigned one voltage tapping-off device (5-42). They can be moved by force independently of one another. A first coil is force-coupled to the vehicle's engine 910) and the second coil to the gearbox 99) of the vehicle's drive. The coils are each moved via pulley belt drives (4-13). A magnet (33) is located in the airgap. The coils are designed as rotationally movable annular coils. The magnet is designed as an annular arrangement with integrated permanent magnets or solenoids.
