Patent number: 11859689Abstract: An active control anti-yaw damper (100) is provided. When a piston (2) of the active control anti-yaw damper (100) reciprocates inside a hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder (1) and the oil reservoir; a reversing valve (PV3) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper (100) is in an active mode and adjust a displacement of the piston (2) within the hydraulic cylinder (1).Type: GrantFiled: May 18, 2020Date of Patent: January 2, 2024Assignee: CRRC QINGDAO SIFANG CO., LTD.Inventors: Xu Wang, Haipeng Kong, Xiaoning Cao, Zhenxian Zhang, Haixiao Liang

Publication number: 20230166777Abstract: The invention relates to a bogie for a rail vehicle characterized by a high lightweight construction potential. The bogie (1, 1*, 1**) according to the invention has, for primary suspension, a torsion spring system (12) in the inner volume of which a roll stabilizer having a torsion rod (11) is arranged in a torsionally movable manner. The roll stabilizer can be articulated to the car body of the rail vehicle or to the torsion spring system (12). The bogie (1, 1*, 1**) according to the invention advantageously has a particularly large installation space for built-in components.Type: ApplicationFiled: March 29, 2021Publication date: June 1, 2023Applicants: CRRC QINGDAO SIFANG CO., LTD., CG RAIL - CHINESISCH-DEUTSCHES FORSCHUNGS- UND ENTWICKLUNGSZENTRUM FÜR BAHNInventors: Andreas ULBRICHT, Werner HUFENBACH, Florian ZEIDLER, Sansan DING, Zhenxian ZHANG, Yulong GAO, Xiongfei ZHANG, Dawei RUAN, Chao SU, Kejian LIU, Xin CAO

Patent number: 10011287Abstract: A bogie for a high-speed railway vehicle includes a wheel set, an axle box, a primary spring suspension device, a frame, a secondary spring suspension device and a foundation braking device. A wheel of the wheel set has an LMA wheel tread. The foundation braking device is mounted by a three-point hitch structure. The axle box is a structure which is separatable in a vertical direction, and an off-line safety protecting device is mounted at a lower portion of the axle box. A traction rod of the secondary spring suspension device is a single traction rod. A center pin is provided with an integral hoisting device. Two anti-yaw dampers, as a group, are arranged at either side of the secondary spring suspension device, and the two anti-yaw dampers have the same damping coefficient.Type: GrantFiled: November 13, 2015Date of Patent: July 3, 2018Assignee: CRRC QINGDAO SIFANG CO., LTD.Inventors: Lijun Ma, Zhenxian Zhang, Pingyu Zhou, Sansan Ding, Zhiguo Cui, Guoping Zhang
