Electromechanical brake force booster

An electromechanical brake force booster for an electrohydraulic vehicle brake system, the electromechanical brake force booster comprising:

• a drive arrangement for driving at least one actuating device for actuating a brake cylinder, wherein the drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device,
• wherein the gearing has at least one first spur gear and at least one second spur gear, the first spur gear and the second spur gear both driving the actuation device,
• wherein the gearing furthermore has an intermediate gearing stage which couples the electric motor to the first spur gear and to the second spur gear in torque-transmitting fashion, wherein the intermediate gearing stage comprises a gearwheel which drives the first spur gear directly and which drives the second spur gear via at least one intermediate gear of the intermediate gearing stage,
• wherein the intermediate gearing stage has at least one first gearwheel and at least one second gearwheel coaxial to the first gearwheel, the second gearwheel being the gearwheel which drives the first spur gear directly and which drives the second spur gear via the at least one intermediate gear of the intermediate gearing stage, wherein an input gearwheel and the first gearwheel of the intermediate gearing stage are arranged in a first plane perpendicular to the axis of rotation (A1) of the electric motor,
• wherein the second gearwheel, the first spur gear, the intermediate gear and the second spur gear are arranged in a second plane perpendicular to the axis of rotation (A1) of the electric motor, the second plane being different than the first plane.
