The invention relates to an assembly for a vehicle brake system, which comprises at least one brake cylinder and an electromechanical brake booster, having a drive arrangement for driving at least one actuating device designed for actuating a brake cylinder, wherein the drive arrangement has at least one electric motor and a gear mechanism for coupling the electric motor to the at least one actuating device, wherein at least one fastening device is provided for fastening the assembly to a vehicle, said fastening device defining a fastening plane. According to the invention the rotary shaft of the electric motor is arranged perpendicular to the longitudinal axis of the actuating device and at an angle of between 60&#xb0; and 120&#xb0; to the fastening plane.

Assembly having a brake cylinder and an electromechanical brake booster

The electromechanical brake force booster for a vehicle brake system comprises a drive arrangement for driving at least one actuating device which is designed for actuating a brake cylinder. The drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device. The gearing comprises at least one second spur gear and at least one first spur gear. Furthermore, the gearing has an intermediate gearing stage. The intermediate gearing stage couples the electric motor to the second spur gear and to the first spur gear in torque-transmitting fashion. The intermediate gearing stage drives the second spur gear directly and the first spur gear via at least one intermediate gear.

A planetary gear device having two sun gears with different diameters that engage with double planet gears having a first gear teeth area, which interacts with the fist sun gear, and a second gear teeth area, which interacts with the second sun gear. The double planet gears are continuous helical gear wheels. The crown circle diameters of the gear teeth areas of the double planet gears and the crown circle diameters of the sun gears are adapted such that the pitch circle diameters between the double planet gears and the sun gears are arranged in the center between the crown circle diameters and the effective root diameters of the gear teeth areas of the double planet gears and the sun gears.
