Patent number: 10604133Abstract: A brake booster for a brake master cylinder of a motor vehicle, including a drive motor, which is connected/is connectable via a transmission to a pressure piston for the brake master cylinder, the transmission including a rotatable spindle nut having an inner thread, and a rotatably fixed axially displaceable spindle rod having an outer thread, the threads engaging with one another in order to convert a rotational movement of the drive motor into a translational movement of the spindle rod, and the spindle nut including an outer toothing, which is engaged with a toothing of a drive wheel of the transmission. It is provided that the spindle nut is displaceable axially relative to the drive wheel.Type: GrantFiled: July 13, 2016Date of Patent: March 31, 2020Assignee: Robert Bosch GmbHInventors: Andreas Deberling, Andreas Ohm, Daniel Weissinger, Markus Baur, Willi Nagel

Patent number: 10543825Abstract: A brake booster for a main brake cylinder of a motor vehicle includes a drive motor connected or connectable to a pressure piston for the main brake cylinder via a gear unit, where the gear unit includes a rotatable spindle nut, including a female thread and an axially displaceable, but rotatably fixed, spindle rod that includes a male thread, the male and female threads engaging into each other in order to convert a rotary motion of the drive motor into a translational motion of the spindle rod for actuating the pressure piston. The spindle nut is formed as two pieces and includes an inner part including the female thread and an outer part including an outer toothing, the inner and outer parts being made of different materials.Type: GrantFiled: July 18, 2016Date of Patent: January 28, 2020Assignee: Robert bosch GmbHInventors: Andreas Deberling, Andreas Ohm, Markus Baur, Willi Nagel

Patent number: 10391995Abstract: A brake booster for a brake master cylinder including a drive motor connected via a linkage to a pressure piston for the brake master cylinder, the linkage having a rotatable spindle nut having an internal thread and a nonrotatable, axially displaceable spindle rod having an external thread, the threads interengaging to convert a rotational motion of the drive motor into a translational motion of the spindle rod in order to displace the pressure piston. The spindle nut has an external tooth set that is in engagement with an internal tooth set of a annular drive gear of the linkage. The spindle nut is axially displaceable with respect to the annular drive gear. Except for a first tooth flank of a tooth, which extends in a first axial portion in its longitudinal extent toward an oppositely located tooth flank, tooth flanks of the internal and external tooth sets extend axially.Type: GrantFiled: July 13, 2016Date of Patent: August 27, 2019Assignee: Robert Bosch GmbHInventors: Andreas Ohm, Andreas Deberling

Patent number: 10378623Abstract: 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.Type: GrantFiled: July 29, 2016Date of Patent: August 13, 2019Assignee: ROBERT BOSCH GMBHInventors: Andreas Weh, Matthias Mayr, Andreas Ohm, Andreas Deberling
