Publication number: 20230349399Abstract: Provided are a hydraulic control valve, a hydraulic control system, and a transmission. The hydraulic control valve includes a valve body, a slidable valve cartridge, and a pressing mechanism. A valve hole, a first oil supply port, a second oil supply port, and an oil discharge port are formed at the valve body, and each of the first oil supply port, the second oil supply port, and the oil discharge port is in communication with the valve hole. Both the slidable valve cartridge and the pressing mechanism are accommodated within the valve hole. The slidable valve cartridge has a small end close to an end of the valve hole and a large end abutting against the pressing mechanism. The pressing mechanism is disposed at another end of the valve hole.Type: ApplicationFiled: June 24, 2023Publication date: November 2, 2023Inventors: Zhiling QIU, Wenjiang ZHAO, Lingling FU, Yanjun TAN, Xiaozhe LIN, Ruiping WANG, Ingo SCHOLTEN

Patent number: 11299027Abstract: The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system for a hybrid vehicle adopts a first planetary gear mechanism with two sun gears, the first sun gear rotates with an input shaft, the second sun gear and the input shaft are independent of each other, and the second sun gear achieves different motion states through a second brake or/and a second clutch, and cooperates with a first brake to provide different transmission ratios of four to six gears when an engine and motors are in driving, so that the power system is simple in structure and low in cost, and the fuel economy and acceleration dynamic performance of the power system are improved.Type: GrantFiled: March 14, 2019Date of Patent: April 12, 2022Assignee: NINGBO UMD AUTOMATIC TRANSMISSION CO., LTD.Inventors: Zhiling Qiu, Tejinder Singh, Jun Fu, Choonghyeo Kim, Daguo Luo, Xiaozhe Lin, Ruiping Wang

Patent number: 11267329Abstract: A power system for a hybrid vehicle includes a first planetary gear mechanism and a second planetary gear mechanism that cooperate with each other, wherein a first sun gear rotates with a first input shaft, a second sun gear and the first input shaft are independent from each other, the second sun gear achieve different movement states through a first brake, a second brake and a second clutch, to provide different transmission ratios, so that the power system is simple in structure, low in cost and more flexible in adaptability. Further, a second electric motor is connected with the first input shaft through a third planetary gear mechanism, can reduce the speed of the second electric motor through the planetary gear mechanism, and increase the torque, to effectively reduce the size of the second electric motor or improve the acceleration performance of the vehicle.Type: GrantFiled: February 16, 2021Date of Patent: March 8, 2022Assignees: NINGBO UMD AUTOMATIC TRANSMISSION CO., LTD, ZHEJIANG GEELY HOLDING GROUP CO., LTDInventors: Tejinder Singh, Zhiling Qiu, Weiqian Xie, Jun Fu

Patent number: 11186161Abstract: A hybrid transmission and a vehicle having the hybrid transmission. An engine, a generator, and a motor are coaxially arranged; a first planetary gear set is separately connected to a crankshaft of the engine and a rotor of the generator; a clutch comprises a first driving end connected to a planet carrier of the first planetary gear set and a second driving end connected to a ring gear of a second planetary gear set, wherein the first driving end and the second driving end are involved in engagement and disengagement; a rotor of the motor is connected to a sun gear axle of the second planetary gear set. When the motor performs driving, the clutch is disengaged from the engine and the generator to avoid a drag resistance of the engine.Type: GrantFiled: March 22, 2018Date of Patent: November 30, 2021Assignees: GEELY HOLDING GROUP CO., LTD., NINGBO UMD AUTOMATIC TRANSMISSION CO., LTD.Inventors: Zhiling Qiu, Jun Fu, Daguo Luo, Pengpeng Li, Shiquan Gou, Lin Zhu, Xiaozhe Lin, Ruiping Wang

Patent number: 11180016Abstract: The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system mainly includes an engine, a first motor, a second motor, a first planetary gear mechanism, a second planetary gear mechanism, a first input shaft, a first clutch, a brake, and a second clutch. Since the second motor is connected to the first input shaft through the second planetary gear mechanism, the planetary gear mechanism can reduce the speed of the second motor and increase the torque to effectively reduce the size of the second motor or improve the acceleration performance of the vehicle. Since the first clutch between the first input shaft and the engine is disengaged when driven by the second motor, the drag resistance of the engine is reduced, and the fuel economy of the vehicle is improved.Type: GrantFiled: March 14, 2019Date of Patent: November 23, 2021Assignees: NINGBO UMD AUTOMATIC TRANSMISSION CO., LTD., ZHEJIANG GEELY HOLDING GROUP CO., LTDInventors: Zhiling Qiu, Tejinder Singh, Weiqian Xie
