Patent number: 11077746Abstract: A continuously variable power-split transmission with at least four driving ranges, within which the gear ratio of the power-split transmission can be continuously varied by a variator. A first planetary gearset with a plurality of shafts can be connected via shifting elements with another planetary gearset that also has a plurality of shafts and can be connected with a transmission output shaft. The first planetary gearset comprises four shafts and can be connected, via a first shaft, with a transmission input shaft and a first shaft of the variator. Furthermore, the first planetary gearset is connected, via a second shaft, to a second shaft of the variator, and the first planetary gearset is coupled, via a third shaft, to halves of two shifting elements and, via a fourth shaft, the first planetary gearset is coupled to a shifting element half of a further shifting element.Type: GrantFiled: October 11, 2018Date of Patent: August 3, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Philipp Rechenbach, Benedikt Reick

Patent number: 11047460Abstract: A continuously variable power-split transmission having a planetary gear mechanism arrangement. The planetary gear mechanism arrangement has three planetary gear sets, an input shaft and three output shafts. Furthermore, the transmission has a change-speed gearbox connected to the output shafts, a reverse gear mechanism and a variator. Each of the three planetary gear sets is assigned a respective output shaft. The input shaft is operatively connected in each of the three planetary gear sets via a respective gearwheel pairing to a respective output shaft. The transmission can be shifted by the change-speed gearbox and the reverse gear mechanism into at least eight driving ranges. The variator varies a transmission ratio of the transmission within the driving ranges in a continuously variable manner. The variator is continuously operatively connected to a single one of the three planetary gear sets.Type: GrantFiled: November 16, 2018Date of Patent: June 29, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Benedikt Reick, Stefan Beck, Philipp Rechenbach, Raphael Himmelsbach
