The disclosed electromechanical brake booster for a vehicle brake system comprises a driving arrangement for driving at least one actuation device designed to actuate a brake cylinder. The driving arrangement includes at least one electric motor and a gear mechanism for coupling the electric motor to the at least one actuation device. The gear mechanism comprises at least one first spur gear and at least one second spur gear, the electric motor driving the first spur gear directly and the second gear via at least one intermediate gear.

Electromechanical brake booster

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.

Electromechanical brake force booster

A vacuum brake servo includes a force input element, a control valve actuated by the force input element, a vacuum chamber connected to a vacuum source, and an operating chamber which, depending on the actuation of the force input element, can be connected to either the vacuum chamber or the surrounding atmosphere. The control valve has a control piston that can be actuated by the force input element and, together with a valve element, forms a seal seat having a seal seat diameter between the operating chamber and the surrounding atmosphere. In the area close to the seal seat, a guide channel is provided. When the seal seat is opened, air from the surrounding atmosphere flows into the operating chamber. The guide channel extends axially with a constant flow diameter over a predetermined length, wherein the flow diameter is less than or equal to the seal seat diameter.
