中文摘要:提出了一种金属带—行星齿轮无级变速器,能够扩大无级变速调速范围,同时兼顾传动效率。选取XP型顺时针环流型单环路系统,设计了金属带—行星齿轮无级变速器,通过无级变速和顺时针环流的模式切换,允许调速范围为0.5~3,循环功率小于系统输入功率的33%,对比了金属带和XP型顺时针环流型无级变速器效率特性,通过模式切换,该金属带—行星齿轮无级变速器能够有效优化传动效率。以Matlab/Simulink为平台建立整车仿真模型,选取UDDS循环工况,采用最佳燃油经济性控制策略,对金属带—行星齿轮无级变速器进行仿真。仿真结果表明:在整个UDDS循环工况下, 金属带—行星齿轮无级变速器在低速大转矩时,工作于顺时针环流模式,高速时,工作于无级变速模式,能够兼顾变速范围和传动效率。同时,模式切换时,流过无级变速支路的功率流方向不变,有效避免了系统振动。

Abstract:A metal pushing belt—planetary gear continuously variable transmission (CVT) was presented. It permitted to enlarge the ratio spread of the CVT and simultaneously ensured a better transmission efficiency. The XP type single loop system with a clockwise power circulation was selected. A metal pushing belt—planetary gear CVT was designed. Its transmission ratio was ranged from 0.5 to 3, the circulation power was less than 33% of the system input power. The metal pushing belt CVT and the XP type with clockwise power circulation CVT efficiency characteristics were contrasted. Through mode switching, the metal pushing belt—planetary gear CVT could effectively optimize the transmission efficiency. Taking Matlab/Simulink as a platform, the simulation model of the vehicle was established. Given UDDS driving cycles, using the best fuel economy control strategy for the engine, the simulation results showed that throughout UDDS driving cycle,at low speed and high torque, the operating mode was the clockwise power circulation pattern;at high speed, the operating mode was CVT pattern, the metal pushing belt—planetary gear CVT can reconcile transmission ratio range and transmission efficiency. During mode switch, the power flow direction of the continuously variable branch was invariable, which effectively prevented the system vibration.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
