Patent number: 8511439Abstract: A self-energizing disk brake is described. The brake includes an electric actuator in which an activation force is amplified using a self-energizing device arranged between the electric actuator and a brake lining. The system includes a brake application unit for applying the brake lining to a brake disk with an application movement of the brake lining, relative to the brake disk, having a component extending parallel to a rotational axis of the brake disk and another component extending tangentially to the rotational axis of the brake disk. At least one electromotive drive for activating the brake application unit and at least two brake plungers of the brake application unit are provided. Pressure surfaces of the brake plungers have a recess with a ramp shaped contour for engagingly receiving a rolling element.Type: GrantFiled: September 28, 2005Date of Patent: August 20, 2013Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Johann Baumgartner, Matthias Seidenschwang, Dirk Ganzhorn, Luise Ulrike Bieker nee Rothe

Patent number: 8315771Abstract: A method for controlling a self-energizing disc brake having an electric actuator in which an activation force applied to the actuator is amplified using a self-energizing device arranged between the actuator and brake lining is described. The method has a brake application unit for applying at least one brake lining to one side of a brake disc by carrying out an application movement of the brake lining relative to the brake disc, the application movement having at least a first movement component in a direction parallel to a rotational axis of the brake disc and a second movement component in a direction tangential to the rotational axis of the brake disc. The method includes also controlling at least one electromotive drive for activating the brake application unit. Rotation of the shaft of the electromotive drive is converted to a non-linear displacement of the brake pad in the tangential direction.Type: GrantFiled: September 28, 2005Date of Patent: November 20, 2012Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Johann Baumgartner, Matthias Seidenschwang, Ernst Dieter Bieker, Luise Ulrike Bieker nee Rothe, legal representative, Dirk Ganzhorn

Patent number: 8167096Abstract: An electromechanically or pneumatically operable disc brake, particularly for a commercial vehicle, includes a brake caliper, which straddles a brake disc, a brake application device arranged in the brake caliper, and at least one electromechanically drivable adjusting device for adjusting a clearance between the brake pads and the brake disc. In order to operate the adjusting device, an electric motor is actively connected to the assigned brake pistons. The disc brake is designed such that the brake pistons are connected to the respective brake pad via spring elements that can be displaced in a direction of displacement.Type: GrantFiled: February 12, 2007Date of Patent: May 1, 2012Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Dirk Ganzhorn, Johann Baumgartner, Robert Trimpe, Wolfgang Pahle

Patent number: 7967114Abstract: A clamp device inserted between two parts can prevent a relative movement between a brake disc and a brake caliper of a vehicle brake. The device includes two plates, with adjustable separation by way of at least two rollers running against each other and rolling on roller surfaces on facing inner sides of the plates. When the rollers are located in the region of a first section of the roller surfaces, the separation of the plates for bringing about clamping in an extended state is greater than the separation adopted by the plates to generate clamping in a withdrawn state when the rollers are located in the region of a second section of the roller surfaces. The position of the rollers relative to the roller surfaces may be altered by an actuator.Type: GrantFiled: March 16, 2007Date of Patent: June 28, 2011Assignee: Knorr-Bremse Systeme fuer Nutzfahrzeuge GmbHInventors: Bence Csák, Michael Herges, Dirk Ganzhorn

Patent number: 7510057Abstract: A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.Type: GrantFiled: March 15, 2007Date of Patent: March 31, 2009Assignee: Knorr-Bremse Systeme Fuer Nutzfahrzeuge GmbHInventors: Wolfgang Kiener, Stephan Lange, Johann Baumgartner, Eduard Gerum, Michael Herges, Dirk Ganzhorn, Bence Csàk, Nicolas Savagner, Uwe Neumann, Matthias Gradl, Matthias Schaefer

Patent number: 6851761Abstract: A control process can be carried out during parking braking by way of a parking brake arrangement. The brake is applied by way of a service brake cylinder, and a position of a piston rod is fixed by rotation of a self-locking rotating spindle and application of the rotating spindle to the piston rod or an element connected in front of the piston rod. By additionally rotating the rotating spindle during parking braking, compensation can be made for shrinkages, particularly of a brake disk and/or brake linings, which occur during brake cooling.Type: GrantFiled: October 1, 2002Date of Patent: February 8, 2005Assignee: Knorr-Bremse System Fuer Nutzfahrzeuge GmbHInventors: Johann Baumgartner, Wolfgang Pahle, Dirk Ganzhorn
