Publication number: 20240001944Abstract: A method determines a defect state of a drive train of a vehicle having a drive axle with a drive wheel and a reference axle with a reference wheel. A drive torque generated by a drive is transferrable to an underlying surface by the drive train via the drive wheel and cannot be transferred to the underlying surface via the reference wheel of the reference axle. The method includes: reading-in a drive variable which is dependent on a motor revolution rate of the drive; reading-in a reference variable which is dependent on a reference wheel revolution rate of the reference wheel; determining whether there is a deviation between the read-in drive and the read-in reference variables to determine whether the reference wheel revolution rate is related to the motor revolution rate of the drive. If there is a deviation, a defect state of the drive train is concluded.Type: ApplicationFiled: September 14, 2023Publication date: January 4, 2024Inventors: Dirk Hillbring, Mark Schaper

Patent number: 11835039Abstract: A method for monitoring the functioning of a compressor, which is switchable into a delivery mode and, when in the delivery mode, delivers compressed air via a dryer line of a compressed-air preparation unit into at least one main supply line, from which multiple supply lines of compressed-air consumer circuits branch off, wherein a pressure sensor is connected at each of at least some of the supply lines, is disclosed. The method results in outputting a warning message if a weighted pressure gradient grd_pV_W has not exceeded a gradient limiting value grd_pG_W within a predefined monitoring time period TM.Type: GrantFiled: July 2, 2019Date of Patent: December 5, 2023Assignee: ZF CV Systems Hannover GmbHInventors: Stefan Brinkmann, Dirk Hillbring, Heinrich Diekmeyer

Patent number: 11794713Abstract: A method for leakage monitoring of a compressed air system of a motor vehicle is disclosed. The compressed-air system has a compressed air supply system, a compressor, and a plurality of compressed-air consumer circuits. The method includes: a) successive detection of a supply pressure via a pressure sensor in a main supply line or in a supply line of at least one compressed air consumer circuit at a predefined time interval; b) successive calculation of pressure gradients of the supply pressure from at least two consecutively detected pressure values; c) comparison of the determined pressure gradients with a predefined gradient limit value; and d) output of a warning signal when the pressure gradient within a predefined monitoring time period which comprises a plurality of delivery pauses of the compressor has not exceeded the gradient limit value.Type: GrantFiled: January 14, 2020Date of Patent: October 24, 2023Assignee: ZF CV Systems Hannover GmbHInventors: Stefan Brinkmann, Heinrich Diekmeyer, Dirk Hillbring

Patent number: 11320007Abstract: A method is disclosed for monitoring the functions of a friction clutch which is arranged in a vehicle between a drive motor and a compressor of a compressed air supply system and which can be disengaged and engaged pneumatically. In a delivery mode of the compressor, at least one operating parameter is detected by sensor and evaluated in an electronic control unit. When a slipping condition of the friction clutch is identified, a value for a cut-off pressure of the compressor stored in the electronic control unit is reduced. When a slipping condition has been identified, the delivery mode of the compressor is ended by disengagement of the friction clutch, and a warning signal and/or warning information is outputted.Type: GrantFiled: February 19, 2019Date of Patent: May 3, 2022Assignee: ZF CV SYSTEMS HANNOVER GMBHInventors: Stefan Brinkmann, Dirk Hillbring, Konrad Feyerabend, Volker Gniesmer, Ralf Stoffels

Publication number: 20210323529Abstract: A control module for an air treatment system of a utility vehicle comprises the following: a first and second pneumatic magnetic valve having a first or second coil, connecting pins, and armatures accommodated in the coils, a circuit carrier, and a module housing that is cast from a plastic material, into which housing the coils are cast. The connecting pins project from a first side of the module housing and are electrically connected to the circuit carrier. A plug-in connection for receiving a connection plug is formed in the module housing, wherein the plug-in connection has plug-in pins, which extend through the module housing and are electrically connected to the circuit carrier. The module housing has a mounting surface having pneumatic connections for installation on an air dryer housing of an air dryer.Type: ApplicationFiled: August 2, 2019Publication date: October 21, 2021Inventors: Heinrich DIEKMEYER, Joachim HEIDER, Dirk HILLBRING, Andreas TEICHMANN

Patent number: 9951897Abstract: An elastic seal element seals a fluid passage between a first component and a second component from the surroundings, the fluid passage passing through the seal element. The seal element has a first bead, which provides a sealing line to sealingly contact the first component around the fluid passage. The seal element further has a second bead, which provides a second sealing line to sealingly contact the second component around the fluid passage. The seal element has a tubular shape, a tubular casing extending between the first bead at the first end of the seal element and the second bead at the second end of the seal element, wherein the tubular casing allows a transversal offset of the second bead relative to the first bead to seal the fluid passage by the seal element even when the second component is offset transversely relative to the first component.Type: GrantFiled: October 31, 2013Date of Patent: April 24, 2018Assignee: WABCO GmbHInventors: Heinrich Diekmeyer, Yves Hansen, Joachim Hein, Dirk Hillbring, Hauke Kraus
