Patent number: 8985714Abstract: Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the ‘brake-by-wire’ type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode.Type: GrantFiled: May 2, 2012Date of Patent: March 24, 2015Assignee: Continental Teves AG & Co. OHGInventors: Holger von Hayn, Jürgen Schonlau, Manfred Rüffer, Wolfgang Ritter, Holger Kranlich, Jose Gonzalez, Thomas Sellinger, Milan Klimes, Torsten Queiβer, Michael Haber

Publication number: 20070266816Abstract: The present invention relates to an adjustable pedal device including at least two pedals whose initial position is variable. A pedal device is disclosed wherein a control member is rotatably articulated at the pedal lever for the brake, while the lever is rotatable about a third axis. It is disadvantageous in the prior art construction that a second pedal, particularly an accelerator pedal, cannot be simultaneously adjusted according to said principle because the forces acting upon the individual pedals are not effective in the same direction. The invention relates to a pedal device which has a simple design and in which the initial position of the mentioned two pedals can be adjusted in a substantially uniform manner, the two pedals being mounted in a twistable mounting support while being rotated about axes that are offset one relative to the other.Type: ApplicationFiled: June 21, 2007Publication date: November 22, 2007Inventors: Ralf Jakobi, Horst Kramer, Michael Haber, Jurgen Schonlau, Holger Kranlich, Thomas Sellinger

Patent number: 6851767Abstract: The present invention relates to an actuator for an electro-hydraulic braking system of the ‘brake-by-wire’ type comprised of a hydraulic pressure generator or master brake cylinder and a travel simulator, with said master brake cylinder including at least one piston that is operable by an actuating pedal, and wherein a device for detecting a driver's deceleration wish is provided, said device cooperating with said piston and being at least partly arranged in a master brake cylinder housing. To optimize the assembly in terms of packaging, production costs, weight, and function, the present invention discloses that the device for detecting a driver's deceleration wish comprises an annular housing embracing the piston in a radial direction and accommodating signal receiving elements which cooperate with signal transmitting elements mounted on the piston surface.Type: GrantFiled: August 31, 2001Date of Patent: February 8, 2005Assignee: Continental Teves AG & Co., OHGInventors: Peter Drott, Horst Krämer, Holger Kranlich, Jan Hoffmann

Patent number: 6808238Abstract: The present invention relates to an operating unit for an electrohydraulic braking system of the ‘brake-by-wire’ type, which is designed as a tandem master cylinder having a first and a second piston biased by each one resetting spring in opposition to the actuating direction. The first pressure chamber of the tandem master cylinder is connected to a hydraulic chamber defined by a simulator element. The simulator element also defines a simulator chamber accommodating a simulator spring and connected to a pressure fluid supply reservoir. A valve device is provided which closes or opens the hydraulic connection between the simulator chamber and the pressure fluid supply reservoir.Type: GrantFiled: September 27, 2002Date of Patent: October 26, 2004Assignee: Continental Teves AG & Co., oHGInventors: Peter Drott, Horst Krämer, Jan Hoffmann, Holger Kranlich

Patent number: 6315086Abstract: The present invention discloses an electromechanically operable disc brake for automotive vehicles which is comprised of a floating caliper and an actuating unit arranged on the caliper. The actuating unit includes an electric motor which, by the intermediary of a threaded roller pinion with return of the threaded rollers, readjusts an actuating element in which one of two friction linings which are mounted displaceably in the brake caliper is moved into engagement with a brake disc. Especially with a view to minimizing the influence of disturbing forces and moments, the spindle of the threaded roller pinion is drivable by the electric motor and the actuating element is formed by the threaded nut of the threaded roller pinion according to the present invention.Type: GrantFiled: May 30, 2000Date of Patent: November 13, 2001Assignee: Continental Teves AG & Co., OHGInventors: Stefan Schmitt, Holger Kranlich

Patent number: 6230854Abstract: The present invention discloses an electromechanically operable disc brake for automotive vehicles which comprises a floating caliper as well as an actuating unit arranged on the caliper. The actuating unit includes an electric motor which, by the intermediary of a reduction gear, readjusts an actuating element which is used to move one of two friction linings that are slidable in the brake caliper into engagement with a brake disc. To permit an individual adjustment of the desired brake force, especially for use of the disc brake in an automotive vehicle, according to the present invention, a force-measuring device (23) is interposed in the flux of force between the caliper (1) and the actuating unit (2), and the output signals of device (23) are adapted to be sent to a control circuit (26) that influences the current supplied to the electric motor (6), and/or the voltage.Type: GrantFiled: September 22, 1999Date of Patent: May 15, 2001Assignee: Continental Teves AG & Co., OHGInventors: Ralf Schwarz, Peter Kilian, Martin Semsch, Holger Kranlich, Stefan Schmitt
