Publication number: 20230375050Abstract: Disclosed is a brake application mechanism for a disc brake in a utility vehicle, having a pivotable brake lever that is supported on an inner wall of a brake caliper and, indirectly, on a bridge which is movably disposed in the brake caliper and which supports at least one brake pad, wherefor an axially and radially secured antifriction roller is disposed between the brake lever and the bridge. The disclosed brake application mechanism is designed such that the antifriction roller rests on the bridge in such a way as to be prevented from rotating and sliding.Type: ApplicationFiled: August 26, 2021Publication date: November 23, 2023Inventors: Julian DAHLENBURG, Christian STOEGER, Andreas PETSCHKE, Natalie ROTH, Maximilian HAUSER, Michael HIDRINGER, Thomas BECK, Martin HEINDL, Dimitrij HABERMANN, Thomas THALER, Frederic SCHROEPF, Thomas EICHLER

Patent number: 11125286Abstract: A disc brake includes a brake caliper that engages over a brake disc and is designed as a sliding caliper. The disc brake has two brake pads which are located in the brake caliper, can be moved in opposite directions and each of which has a pad backing plate with a friction lining secured thereon. An action-side or application-side brake pad of the two brake pads can be pressed against the brake disc by a brake application device with the aid of at least one brake plunger. The brake also includes at least one restoring device, by which the brake caliper can be returned after a displacement and release of the brakes caused by a braking action. The restoring device has a spreading device which engages on the brake pads lying opposite one another and which acts with an identical force in opposition to the respective application direction. The spreading device includes spring-loaded spreading elements, each engaging on its respective pad backing plate.Type: GrantFiled: December 15, 2017Date of Patent: September 21, 2021Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Jens Fricke, Abdelaziz Rguichi, Thomas Eichler, Oliver Krause, Matthias Klingner, Michael Peschel, Tobias Schoefberger, Philipp Adamczyk, Manfred Schoenauer

Patent number: 11078975Abstract: A resetting device by which a brake caliper can be reset after a braking-induced displacement and release of a brake. The resetting device has a spreading device which has resilient spreading elements. The spreading device is arranged in a central opening of the brake caliper. The spreading elements engage, outside the friction pads, directly or indirectly on one side at at least two abutment regions arranged spaced apart from one another relative to the center, of the brake pads, where the abutment regions have one abutment surface and one bearing surface on which the spreading elements are movably arranged. The spreading device has spring arms, of which in each case two lie against an associated pad carrier plate, where the spring arms are connected to one another in the central region of the opening. The spring arms are connected to a retaining bow which is attached to a brake carrier.Type: GrantFiled: January 2, 2020Date of Patent: August 3, 2021Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Jens Fricke, Abdelaziz Rguichi, Thomas Eichler, Oliver Krause, Matthias Klingner, Michael Peschel, Tobias Schoefberger, Philipp Adamczyk, Manfred Schoenauer, Martin Pleintinger, Markus Molnar, Franz Gasslbauer, Martin Tropp

Patent number: 10855228Abstract: Systems, methods, and circuitries are provided for generating supply voltages for a power amplifier in a digital envelope tracking system. In one example, a voltage generation circuitry converts a source voltage into a supply voltage based on a target voltage. The voltage regulation circuitry includes an adjustable boost circuitry that multiplies the source voltage to generate an input voltage having a voltage equal to or greater than the source voltage and a step-down regulator circuitry that regulates the input voltage to generate a regulated output voltage having a voltage that is less than or equal to the input voltage. A voltage splitter circuitry is coupled to the regulated output voltage and is configured to generate at least one derived output voltage from the regulated output voltage. A supply modulator provides a selected one of the at least one derived output voltage to a power amplifier.Type: GrantFiled: March 29, 2019Date of Patent: December 1, 2020Assignee: Intel CorporationInventors: Thomas Eichler, Stephan Henzler
