Patent number: 11370463Abstract: The application relates to roof segments for constructing a roof of a carriage body for a rail vehicle for passenger transport, in particular for use in short-haul operation, such as underground and suburban trains, the rail vehicles or the train units formed by same must be accelerated and decelerated at short intervals. The roof segments are designed in the form of plates, shells or half-shells and consist of an outer wall and an inner wall at a distance to same. At least two roof segments are configured in such a way that the protruding region of the outer wall or inner wall of one roof segment is interlockingly, force-lockingly and/or integrally connected to the non-protruding region of the outer wall or inner wall of the neighbouring roof segment. The roof segments consist at least partially of a fibre-reinforced plastic composite.Type: GrantFiled: February 8, 2018Date of Patent: June 28, 2022Assignees: CRRC QINGDAO SIFANG CO., LTD., CG RAIL—CHINESISCH-DEUTSCHES FORSCHUNGS—UND ENTWICKLUNGSZENTRUM FÜR BAHN—UND VERKEHRSTECHNIK DRESDEN GMBHInventors: Shaoqing Liu, Zhicheng Guo, Zhengyu Song, Dongyuan Liu, Jiajie He, Qinshu Tu, Werner Hufenbach, Andreas Ulbricht

Patent number: 11303187Abstract: An engine-and-electric-machine assembly is provided that includes an engine and an electric machine, a crankshaft being provided in the engine, the crankshaft including a main body and an extension section that extends out to the exterior of the engine, the extension section forming a rotation shaft of the electric machine, and a rotor of the electric machine being mounted on the extension section. Moreover, a terminal of the rotation shaft is connected to a coolant pump, a rotor of the coolant pump is mounted to the rotation shaft, and while the rotation shaft is rotating the rotation shaft drives the coolant pump to provide coolant to the electric machine. By connecting the rotation shaft of the electric machine to the coolant pump, the assembly enables the pump to be highly integrated into the system and reduce manufacturing cost.Type: GrantFiled: September 10, 2020Date of Patent: April 12, 2022Assignee: JING-JIN ELECTRIC TECHNOLOGIES CO., LTD.Inventors: Xinliang Ling, Zhicheng Guo, Yao Zhou, Ping Yu
