Constant Power Continuously Variable Transmission ( CP-CVT ): Operating Principle and Analysis 常功率无级变速器(CP-CVT)工作原理和分析
Based on the control method of segmental constant engine speed, the mathematic model of reflux continuously variable transmission system and the control strategy of the starting clutch are proposed. It provides theoretical basis to design, fabricate and exploit vehicle with the reflux continuously variable transmission. 采用离合器局部恒转速控制方法,建立回流式无级自动变速传动系统的数学模型和离合器起步自动接合控制策略,为新型无级自动变速系统的研制和开发提供设计理论依据。
Different from circular gear-drives with constant speed ratio, non-circular gears can realize the variable velocity-rate transmission, they are widely used in light industry -, textile -, tobacco - and foodstuff-machines, and play an important role in the creative design of mechanism. 与定速比传动的圆齿轮不同,非圆齿轮能实现变速比传动,广泛应用与轻工、纺织、烟草、食品等机械中,在机构创新设计中具有重要作用。
Mechanical property of motor vehicle steering link system has been analysed, defect of constant speed ratio transmission of gear and rack type steering gear and necessity of adopting variable speed ratio transmission are pointed out. 对汽车转向系杆系的力学特性进行了分析,指出了齿轮齿条式转向器采用定速比传动的缺点及采用变速比传动的必要性。
