摘要： 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.

摘要： 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.

摘要： A hydraulic block includes pedal travel simulator for a hydraulic power-assisted vehicle braking system includes a piston that is displaceable in a cylinder, a piston spring that acts on the piston against the displacement, and a stroke limiter limiting the displacement. A characteristic curve of such a pedal travel simulator is set.

摘要： A hydraulic block is described for a braking system of a vehicle including at least one check valve, which is situated in a check valve receiving bore extending partially through the hydraulic block, including a valve seat and a valve body, the check valve receiving bore being formed as a stepped recess into the hydraulic block including a first subarea having at least one minimum diameter and an inner second subarea having at most one maximum diameter smaller than the minimum diameter; the valve seat is inserted onto and/or into the check valve receiving bore in a direct contact with at least one inner wall of the check valve receiving bore; and the valve body being inserted cageless and adjustable within the first subarea of the check valve receiving bore. 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
