An actuating unit for a brake booster of a vehicle is disclosed, the actuating unit having a housing and a force transmission module which is received displaceably in the housing. The force transmission module has a first force transmission element, a second force transmission element which is couplable or coupled to the first force transmission element so as to transmit force, a spring device which is couplable or coupled to the second force transmission element so as to transmit force and an actuating element which is couplable or coupled to the first force transmission element. The spring device is configured to exert a spring force on the first and/or second force transmission element such that the first and/or second force transmission element is able to be held at least temporarily in a predetermined initial position. The first and/or second force transmission element is adjustable from the initial position counter to the spring force of the spring device by an adjustment path by a force exerted and/or transmitted onto the first force transmission element. The force transmission module is configured to decouple the first force transmission element from the spring device after a defined adjustment path, as well as a brake booster, vehicle brake system and subassembly therefor.

Actuating unit, brake booster, vehicle brake system and subassembly therefor

An electrically actuatable operating unit () for a motor vehicle brake comprises a housing body () which is arranged so as to be displaceable in a braking direction for operation of the motor vehicle brake, a recess () formed in the housing body (), wherein the recess () is delimited at one longitudinal end by a contact shoulder (), a through-opening () delimited by the contact shoulder (), an operating member () which is arranged in the recess () so as to be displaceable for operation of the motor vehicle brake and projects through the through-opening () of the contact shoulder (), wherein the operating member () can be arranged in a force-transmitting manner between a brake pedal and the motor vehicle brake (). The operating unit () further comprises a return spring () which is arranged in the recess () and is configured to move the operating member () relative to the housing body () away from the contact shoulder (), and a sleeve element () which circumferentially surrounds a portion of the operating member () at least partially and is held in contact with the contact shoulder () by the return spring (), and wherein the sleeve element () projects into the through-opening () in such a manner that it is arranged between the operating member () and an inner circumferential surface of the contact shoulder () that delimits the through-opening ().

Electrically actuatable operating unit for a motor vehicle brake, brake booster having such an electrically actuatable operating unit, and motor vehicle brake system having such a brake booster

A brake booster is comprised of an actuation unit, which can be coupled to a brake cylinder. The actuation unit is comprised of at least one actuation element that can be coupled to an electric motor via a transmission and at least one actuation element that can be coupled to a power input element. The actuation unit also includes at least one power transmission element that can be coupled to at least one actuation element in a power-transmitting manner, and at least one power take-up element that can be coupled or is coupled to an actuation detection device for the detection of an actuation of the electromechanical brake booster. The power take-up element can be coupled or is coupled to at least one actuation element. The power take-up element is configured to limit a relative movement of the actuation element relative to the power transmission element.

Electromechanical brake booster, vehicle brake system and assembly for this

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.

Electromechanical brake force booster

A vacuum brake booster for a motor vehicle brake system, comprising a displaceable force input member that is coupled to or can be coupled to a brake pedal, a chamber arrangement arranged in a booster housing having at least one working chamber and at least one vacuum chamber, which are separated from one another via at least one movable wall, a control valve assembly that can be actuated by the force input member, and a force output member for transmitting an operating force to a downstream brake system. The at least one working chamber can be fluidically connected optionally to a negative pressure source or the atmosphere by way of the control valve assembly. The control valve assembly comprises a control valve housing, in which an actuating piston that is coupled with the force input member s displaceably arranged, and a first valve seat, and a second valve seat. Upon an actuation of the force input member, a throttle sleeve can be displaced from the initial position relative to the control valve housing by a predetermined functional path. During the displacement, the throttle sleeve is in abutment with the actuating piston such that a fluidic connection between the at least one working chamber and the ambient atmosphere by way of a throttle window is present. Upon exceeding the functional path, the throttle sleeve lifts off the actuating piston.
