Publication number: 20250369648Abstract: An electric fluid heater includes a fluid-conducting housing in which at least one tubular heating element each with a plurality of coils is arranged. An inner region extends along a coil axis and is delimited by the coils. A displacer body arrangement with at least one displacer body is provided in the inner region, wherein a flow region for the fluid is formed on the outer circumference of the displacer body arrangement. The coils are also arranged in the flow region. An interior space arrangement with at least one interior space of the displacer body arrangement is separated from the flow region of the fluid largely or completely in a fluid-tight manner. A transverse flow is very substantially or completely avoided.Type: ApplicationFiled: June 20, 2023Publication date: December 4, 2025Applicant: DBK David + Baader GmbHInventor: Alaa HARMOUCH

Patent number: 11242910Abstract: A plate link chain for a continuously variable cone pulley transmission is disclosed. The plate link chain includes a first chain link, a second chain link, and a third chain link having plates and being connected to one another by joints having rocker pins. The rocker pins have end faces configured to transmit friction forces between the plate link chain and cone pulleys, wherein at least one of the plates has at least one overlapping tip. The first, second, and third chain links form a triplet and have different plate assemblies comprised of a first plate unit or a second plate unit, each of the chain links having at least one plate positioned transversely to a running direction of the plate link chain and are repeated in the running direction of the plate link chain.Type: GrantFiled: August 24, 2016Date of Patent: February 8, 2022Assignee: Schaeffler Technologies AG & Co. KGInventors: Alaa Harmouch, Yudhi Lukito, Stephan Penner, Carsten Trautmann

Patent number: 10883576Abstract: A plate link chain for a continuously variable transmission in a motor vehicle comprising chain links. The chain links have link plates coupled to one another by pairs of rocker pins and at least two different sprocket pitches. At least one absorption mass is arranged between two pairs of rocker pins in an absorption space within a link plate inner contour.Type: GrantFiled: August 25, 2016Date of Patent: January 5, 2021Assignee: Schaeffler Technologies AG & Co. KGInventors: Alaa Harmouch, Sandra Schaub, Stephan Penner

Patent number: 10619705Abstract: A plate link chain for a continuously variable transmission of a motor vehicle is provided. The plate link chain includes a plurality of link plates arranged parallel to a running direction of the plate link chain and each link plate includes an aperture formed therein. A plurality of pressure pieces are oriented perpendicular to the running direction and arranged in pairs to be received in the apertures of the link plates to form two joints in each link plate. The two joints in each link plate are supported by arcuate outer sections of the pressure pieces.Type: GrantFiled: April 28, 2016Date of Patent: April 14, 2020Assignee: SCHAEFFLER TECHNOLOGIES AG & CO. KGInventors: Alaa Harmouch, Konstantin Braun

Patent number: 10295016Abstract: A plate link chain for a continuously variable transmission of a motor vehicle. The chain is formed from longer and shorter chain links that are formed from and that include respective longer and shorter link plates that are coupled to each other by pairs of rocker pressure members. Both the shorter link plates and the longer link plates have at least one longitudinally extending external appendage.Type: GrantFiled: November 20, 2015Date of Patent: May 21, 2019Assignee: SCHAEFFLER TECHNOLOGIES AG & CO. KGInventors: Konstantin Braun, Stephan Penner, Alaa Harmouch, Jürgen Ochs
