  • Patent number: 10378623
    Abstract: A rotation/translation converter gear unit having a helical gear and a planetary gear for driving the helical gear. A spindle nut of the helical gear forms a planet carrier for planet wheels of the planetary gear. Situated between the planetary gear and the helical gear is an axial friction bearing, that at the same time forms a centering element which centers a sun wheel of the planetary gear between the planet wheels. In particular, the rotation/translation converter gear unit is used to drive a piston of a pressure generator for a brake control of a hydraulic vehicle brake system.

  • Publication number: 20190232934
    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.

  • Patent number: 10150458
    Abstract: A hydraulics block having a piston-cylinder unit that can be driven by an electric motor via a gear in order to generate a brake pressure for a hydraulic non-muscular-energy vehicle brake system. An annular cavity is provided which encloses a piston of the piston-cylinder unit inside a cylinder, as a leakage chamber which communicates with a reservoir. Possible drag leakage is carried away in this manner. An end shield situated between the electric motor and the gear prevents lubricant or leakage from entering the electric motor.
