A device for the electromotive regulation of an actuating device of an automotive vehicle including an electromotive adjusting device for at least one actuating member and a control unit that is electrically connected thereto, which, in turn, is connected to electric switching device, and that at least one actuation detection means that is connected electrically to the control unit is provided to monitor an actuation of the actuating member so that in the case of a safety-critical condition an electric signal which locks the electromotive regulation can be sent from the control unit, or the energization of the electromotive adjusting device can be interrupted. The present invention prevents an electromotive regulation to take place at an inappropriate time, that means during safety-critical conditions, e.g., during a brake application or when the vehicle is moving.

Device and method for the electromotive regulation of an actuating device

The present invention relates to a reaction force transmission mechanism for a pneumatic brake booster including a largely incompressible reaction plate that is interposed between an input member and an output member and encased at the peripheral side and has lateral abutment surfaces for the input member and the output member, wherein the abutment surface close to the input member can be acted upon by a pressure member which is adapted to be fixed to a control housing and, consequently, can be excepted from the transmission of the reaction force to a vehicle driver. To improve its service life, the reaction plate includes a recess in the area of the abutment of a valve piston extension, in which recess a substantially incompressible, elastic insert is placed.

Reaction force transmission mechanism for a pneumatic brake booster

The present invention relates to a vacuum brake force booster which includes a valve piston with a pedal push rod that is axially slidable in a vacuum housing, further including a control housing and a poppet valve connected to the valve piston, and an air filter. The air filter is arranged in the valve piston and forms, in conjunction with an associated valve piston sealing seat for the air filter abuttable thereon, a variable flow cross-section for the outside air that flows through the poppet valve.

Vacuum brake booster

The present invention relates to a brake force booster with a panic braking function for automotive vehicles. The present invention includes that the first sealing seat arranged movably in relation to the control housing wherein the sealing seat is fixed to a lever such that when a predetermined relative displacement between valve piston and control housing is exceeded so that the lever prevents at least a movement of the sealing seat in the actuating direction. The brake force booster with a brake assist function is easy to manufacture and, in addition, ensures a controllability of the brake force in the emergency braking position.

Brake force booster with a panic braking function

The present invention relates to a brake-power transmission device, especially for motor vehicles, including an actuated input member, an output member to exert a boosting force, especially on a main brake cylinder, and a control valve arranged in a control housing to regulate the boosting force. An axially movable pressure piece is provided in the area of a reaction member. The pressure piece is supported on the input member or the control housing, thereby permitting changes to be made in the power transmission ratio. There is a general need to provide a brake-power transmission device that enables increased boosting only when required and that allows for mechanical sensing of the brake actuation speed so that immediate maximum boost force can be exerted when required without any time delay. According to the present invention this is achieved by detachably connecting the pressure element to the control housing by way of a coupling element in order to increase boosting on the basis of a relative movement between the input member and the control housing.

Brake power transmission device, especially for motor vehicles

The brake force booster with panic brake function includes a control valve, which is arranged in a control housing and operable by way of an input member, for controlling the boosting pressure in a working chamber, the said control valve including an atmosphere sealing seat on a valve piston and a vacuum sealing seat which is arranged on a sliding sleeve that is axially slidably mounted in the control housing. In the event of a panic braking, a quick depression of the brake pedal causes advance movement of the valve piston connected to the input member in relation to the control housing and the sliding sleeve, whereby opening of the atmosphere sealing seat is initiated and a clutch device is actuated which leads to supporting the sliding sleeve in the brake actuation direction on the elastically deformable reaction member, to which latter both the mechanically generated brake force and the pneumatic boosting force is applied. The clutch device is released by withdrawal of the input member. The sliding sleeve is supported on the reaction member by way of a member, by way of which also the mechanical brake force is transmitted to the reaction member.
