  • Patent number: 12162449
    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.

  • Patent number: 12098716
    Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The electromechanical brake pressure generator encompasses a screw drive assemblage for converting an input-drive-side rotational motion into a translational motion for brake pressure generation. The screw drive assemblage encompasses a spindle that is rotatable via an electric motor, a spindle nut that interacts with a thread of the spindle so that the spindle nut is axially displaceable with a rotation of the spindle, and a housing that at least partly surrounds the spindle and the spindle nut. The screw drive assemblage additionally encompasses a drive wheel, which is disposed nonrotatably on the spindle and by way of which the spindle is connected to the electric motor. The spindle and the drive wheel are mounted, via a common bearing, rotatably with respect to the stationary housing. The bearing is radially surrounded at least partly by the drive wheel.
