Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The electromechanical brake pressure generator includes at least one threaded drive system for converting a drive-side rotary motion into a translatory motion for the brake pressure generation. The threaded drive system includes a rotatable spindle nut, and a spindle cooperating with a thread of the spindle nut so that the spindle is axially displaceable with a rotation of the spindle nut. The threaded drive system includes a drive wheel, which is non-rotatably situated on the spindle nut and via which the spindle nut is connected to the electric motor, the drive wheel and the spindle nut being designed as separate plastic components, including a plurality of mutually corresponding connecting structures which, in the assembled state, engage one another in a form-locked manner in such a way that a torque required for rotating the spindle nut is transmittable.

Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The brake pressure generator has a spindle drive unit for converting an input-drive-side rotational motion into a translational motion for piston actuation of a hydraulic piston/cylinder unit. A multi-stage gear linkage is disposed between the spindle drive unit and an electric drive motor. The gear linkage encompasses a planetary gearset unit driven by a motor pinion constituting a sun gear, the output-drive-side ring gear of which unit drives the spindle drive unit. A motor shaft of the electric drive motor extends in adjacently parallel fashion next to a spindle drive shaft of the spindle drive unit.

Abstract: An electromechanical brake pressure generator including a spindle drive unit for converting a rotational motion of an electric motor-driven drive shaft into a translatory motion of a piston that is coupled to the spindle drive unit, the spindle drive unit being operatively connected to the drive shaft via a multi-stage transmission. The multi-stage transmission is a planetary gear set having a first and a second stage. With the aid of the transmission, a spindle or a spindle nut of the spindle drive unit is drivable, which is rotatably mounted in a housing of the brake pressure generator via a bearing assembly receiving axial and radial forces. A braking system for a vehicle including an electromechanical brake pressure generator is also described.

A hydraulic block of the piston/cylinder unit also at least partially accommodates the electric motor unit in such a way that a motor shaft of the electric motor unit extending at least predominantly in the area of the hydraulic block is situated axially parallel to a longitudinal axis of the piston of the piston/cylinder unit which is movable in the hydraulic block.

Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle, including a threaded drive system for converting a drive-side rotary motion into a translatory motion for brake pressure generation. The system includes a spindle rotatable via an electric motor, a spindle nut cooperating with a thread of the spindle so the spindle nut is axially displaceable with a rotation of the spindle and a brake fluid is loadable or relievable, and a housing which, together with the spindle nut, forms an anti-twist protection which secures the spindle nut against twisting during rotation of the spindle. The spindle nut forms at least one spindle nut reference surface, which cooperates with at least one stop surface, which is stationary with respect to the housing, in a relief end position of the spindle nut in such a way that an instantaneous axial position of the spindle nut is determinable therefrom.

Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle, including at least one threaded drive system. The system includes a hydraulic piston, a spindle and a spindle nut, which cooperate via a thread, and includes an electromotive drive, via which the spindle and the spindle nut are rotatable relative to one another. The hydraulic piston of the piston/cylinder unit at least partially radially surrounds the spindle and the spindle nut, the hydraulic piston being accommodated in a hydraulic cylinder of the piston/cylinder unit. An anti-twist protection is formed by a recess extending in the axial direction and forming a sliding surface, and by a sliding element protruding into the recess. The sliding element rests against a planar contact area of the sliding surface so that the hydraulic piston is secured against twisting and is axially displaceable by a rotation of the spindle or the spindle nut.

The system includes a housing which at least partially surrounds the hydraulic piston and forms a hydraulic cylinder, and an axial recess, in the hydraulic cylinder, which forms an anti-twist protection together with a torque support formed at the hydraulic piston and using which the hydraulic piston and the spindle are secured against twisting during a rotation of the spindle nut, the recess forming a sliding surface for the torque support of the hydraulic piston.

Abstract: A method for semiconductor processing is provided, wherein a semiconductor wafer having undergone polishing is provided. The semiconductor wafer has an active region positioned between one or more moat regions, wherein the one or more moat regions have an oxide disposed therein. A top surface of the active region is recessed from a top surface of the moat region, therein defining a step having a step height associated therewith. A step height is measured, and a photoresist is formed over the semiconductor wafer. A modeled step height is further determined, wherein the modeled step height is based on the measured step height and a desired critical dimension of the photoresist. A dosage of energy is determined for patterning the photoresist, wherein the determination of the dosage of energy is based, at least in part, on the modeled step height. The photoresist is then patterned using the determined dosage of energy.
