Abstract: In a pedal feel simulator, in particular for a vehicle brake system, with a piston guided axially displaceably in a cylinder bore against a spring force, the piston is designed in two parts from a first piston part and a second piston part, wherein the first piston part is adapted to be designed identically across several pedal feel simulator types, and the second piston part is designed with at least one different axial dimension across several pedal feel simulator types.

Abstract: A pedal travel simulator for a hydraulic powered vehicle braking system. In order to realize a “jump-in,” a first piston spring is provided that, after a first displacement path, loads a simulator piston of the pedal travel simulator with a spring force that is higher by a multiple than that of a second piston spring that loads the simulator piston during the first displacement path.

Abstract: A piston of a hydraulic power unit of a hydraulic power vehicle braking system including slip control is guided directly, without a cylinder liner, in a cylinder bore of a hydraulic block. The piston is rotatably fixedly and axially displaceably held in a bushing with the aid of an anti-rotation mechanism, which in turn is rotatably fixed at the hydraulic block. A pivot bearing of a worm gear for displacing the piston is fixed at the bushing.

Abstract: A pedal travel simulator for a hydraulic power vehicle braking system. For the purpose of adapting to different main brake cylinders and of changing a spring characteristic curve, a stop is provided to be pressed into a piston of the pedal travel simulator. A pressing-in depth of the stop delimits a piston stroke.

A braking system for a vehicle and a manufacturing method for a hydraulic block for a braking system of a vehicle including at least one check valve are also described.

Abstract: A hydraulic block of a slip regulation of a hydraulic vehicle power brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a piston of the master brake cylinder against an end stop when the master brake cylinder is released, in particular when there is an abrupt release, for example when the foot slides off a foot brake pedal, a hydraulic return damper that is integrated in the piston is provided.

Abstract: A pedal travel simulator for a hydraulic vehicle power braking system with a cup-shaped cylinder cover in which a piston spring is accommodated, which is held by an orifice disk as a stop for a piston of the pedal travel simulator in the cylinder cover. Recesses are provided in an outer edge of the orifice disk, through which the piston is able to displace brake fluid on its rear side out of a cylinder of the pedal travel simulator through a circumferential groove into a return.

Abstract: The invention relates to a pedal travel simulator (2) for a hydraulic power vehicle braking system. For the purpose of adapting to different main brake cylinders and of changing a spring characteristic curve, the invention provides for a stop (13) to be pressed into a piston (6) of the pedal travel simulator (2). A pressing-in depth of the stop (13) delimits a piston stroke.

Abstract: A screw drive for an electromechanical brake booster of a braking system of a motor vehicle includes: a threaded nut; and a threaded spindle engaged with the threaded nut. The threaded nut includes an outer section which is connectable to a drive unit for driving the threaded nut, and an inner section having a thread for accommodating the threaded spindle. The inner section and the outer section of the threaded nut are connected by a damping unit for damping the torsion of the threaded nut.
