Abstract

An electromechanical brake booster is disclosed. The brake booster is constructed with two worm gears which run in opposite directions and whose axial forces compensate one another. The worm gears drive toothed rack gears which convert a rotational driving movement into a translatory output movement for activating a master brake cylinder. As a result of the provision of two gear paths, the loading of each gear path is halved and an application of force to a booster body, which forms a gear output, is symmetrical.
