Electromechanical brake booster

摘要

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.

主权项

1. An electromechanical brake booster, having:
an electric motor; and a gear mechanism which is driven by the electric motor and which has:
a rotational/translational conversion gear mechanism which converts a rotational drive movement of the electric motor into a translational output movement in order to activate a hydraulic master brake cylinder, anda distributor gear mechanism which distributes a gear mechanism input between at least two gear mechanism paths, the distributor gear mechanism having at least two worm gear mechanisms with a common worm drive, wherein the worm gear mechanisms are parts of the gear mechanism paths,wherein the rotational/translational conversion gear mechanism further acts as a combination gear mechanism which combines the at least two gear mechanism paths into one gear mechanism output.
