Publication number: 20220126807Abstract: An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The brake pressure generator has a spindle drive unit for converting an input-drive-side rotational motion into a translational motion for piston actuation of a hydraulic piston/cylinder unit. A multi-stage gear linkage is disposed between the spindle drive unit and an electric drive motor. The gear linkage encompasses a planetary gearset unit driven by a motor pinion constituting a sun gear, the output-drive-side ring gear of which unit drives the spindle drive unit. A motor shaft of the electric drive motor extends in adjacently parallel fashion next to a spindle drive shaft of the spindle drive unit.Type: ApplicationFiled: February 8, 2020Publication date: April 28, 2022Inventors: Claus Oehler, Mark Boehm, Martin Uhlig, Christoph Oehler, Marc Micke, Konstantin Haberkorn

Patent number: 9982662Abstract: A pressure generator for a hydraulic vehicle brake system includes a piston-cylinder unit, a piston, a ball screw drive configured to move the piston, an electric hollow-shaft motor that surrounds and is configured to drive the ball screw drive, and a planetary gear set configured to transmit a rotational movement of the hollow-shaft motor to the ball screw drive. The generator also includes a flange part, a sleeve, and an axial needle-roller bearing. The flange part has a tubular collar configured to axially guide the piston in a movable fashion therein. The sleeve has a flange configured as a counterbearing which is attached to an interior of the tubular collar, and is further configured to support the bearing. The bearing is configured to rotatably mount and axially support the ball screw drive.Type: GrantFiled: June 26, 2015Date of Patent: May 29, 2018Assignee: Robert Bosch GmbHInventors: Andreas Weh, Marc Micke, Roman Koch, Matthias Mayr

Patent number: 7265538Abstract: A method and a device for measuring the speed of a pulse-activated electric motor are described. According to this method, the motor is fully activated at time intervals to be determined for a defined measuring time by the circuit element provided for timing and, in this time, the frequency of the current ripples, which is proportional to the motor speed, is measured. A current-proportional voltage measuring device is located on the circuit element, on whose load side are located an amplifier, filters, and an evaluation circuit in the form of a comparator for determining the frequency of the current ripples flowing in a measured phase during which the motor is fully activated.Type: GrantFiled: September 12, 2003Date of Patent: September 4, 2007Assignee: Robert Bosch GmbHInventors: Marc Micke, Holger Sievert, Juergen Hachtel, Guenther Hertlein
