Publication number: 20230415849Abstract: An electric bicycle drive unit mounting arrangement for attaching an electric drive unit at a drive receptacle of a bicycle frame is provided. The bicycle frame has a fixed bearing fastening frame leg and a parallel loose bearing frame leg. A drive unit housing has a fixed bearing housing flange and a parallel loose bearing housing flange. The fixed bearing housing flange is frictionally attached directly against the fixed bearing frame leg. A loose bearing fastening element attaches the loose bearing housing flange to the loose bearing frame leg. The loose bearing fastening element is a loose bearing threaded bolt having a cylindrical bolt head seated in a loose bearing cylinder bore of the loose bearing frame leg without radial play, and has a threaded portion with an external thread screwed in a corresponding internal thread to the loose bearing frame leg or to one of the housing flanges.Type: ApplicationFiled: September 7, 2023Publication date: December 28, 2023Applicant: SRAM, LLCInventors: AXEL HEMSING, KAI VENHOFF, DIETMAR GREVEN

Patent number: 11834128Abstract: A pedelec bottom bracket drive unit includes a rigid drive housing and a tolerance compensation sheet-metal spring which is arranged to stand substantially in a vertical plane. The tolerance compensation sheet-metal spring includes at least one fixing point at a housing side and at least one mounting point for fastening the tolerance-compensating sheet-metal spring to a pedelec-frame-side drive mount. The at least one fixing point has a fixing point traverse axis. The tolerance compensation sheet-metal spring is fixed to the rigid drive housing at the at least one fixing point at the housing side. The at least one mounting point has a mounting point traverse axis. The at least one mounting point is arranged offset with respect to a next adjacent fixing point of the at least one fixing point as viewed from the fixing point traverse axis and from the mounting point traverse axis.Type: GrantFiled: December 19, 2019Date of Patent: December 5, 2023Assignee: SRAM, LLCInventors: Dietmar Greven, Kai Venhoff, Axel Hemsing, Peter Thiele

Patent number: 9915208Abstract: A flap device for an internal combustion engine includes a flow housing comprising a flow channel, an actuating shaft, a flap body arranged on the actuating shaft in the flow channel, a bore comprising a shoulder arranged in the flow housing, a bearing bush arranged in the bore, a closure bush, a slide ring comprising a slide ring inner portion, and a sealing element surrounding the actuating shaft. The actuating shaft is mounted in the bearing bush. The sealing element comprises a membrane with a membrane inner portion and a membrane outer portion. The membrane outer portion is clamped axially between the closure bush and the shoulder to form a contact surface on the bore of the flow housing. The membrane inner portion rests against the slide ring inner portion to form a mating surface which is arranged closer to the flow channel than to the contact surface.Type: GrantFiled: November 5, 2013Date of Patent: March 13, 2018Assignee: PIERBURG GMBHInventors: Axel Hemsing, Karsten Voigtlaender, Uwe Krawinkel
