 摘 要 自动变速器技术是汽车传动技术发展过程中的一项十分重要的发明.他能够使汽车起步平稳、换档平顺、操作方便，简化的手动换档操作，使驾驶更轻松自如。现代自动变速器主要采用液力变矩器和行星齿轮变速箱结合的液力机械式自动变速器（AT）。行星齿轮变速器具有体积小、操纵简单，速比大等优点，可以实现变速和动力传递，加大变速器的传动比范围，同时也能获得空挡和倒档，故被广泛的应用到AT上。行星齿轮还有一个特点就是自由度大于1，故它可以作为动力偶合和分配器。这点在混合动力汽车上得到了很好的体现。本文就对行星齿轮变速器在混合动力汽车中作为扭矩合成器进行分析讨论和设计。本文以丰田PRUIS为原型进行行星齿轮变速器的设计计算和对整车的仿真计算。 1） 在PRUIS原型的基础上对相关的数据进行修改，查阅相关文献参数来确定本次设计计算的参数。 2） 在设定的参数下设计所需的变速器参数，并对所设计的变速器中个零件进行强度校核和寿命校核。 3） 通过建模选择发动机和电动机。 4） 通过ADVISOR仿真软件在ECE+EUDC循环工况下对整车的油耗，发动机功率、电动机功率、最高车速、最大爬坡度等进行仿真。 关键词：变速器，行星排，混合动力  ABSTRACT Automatic transmission car drive technology is a very important invention in the process of technological development。It can start the car stable and smooth shift, easy to operate, to simplify the manual-shift operation, so that more driving ease Modern automatic transmission torque converter and a major planetary gear transmission with the automatic transmission fluid mechanical.(AT) Planetary gear transmission is small, simple manipulation, the advantages of speed ratio can be achieved transmission speed and power, increase the transmission of the transmission ratio, but also can be neutral gear and Dao Dang, it was widely used on the AT. There is also a feature of planetary gear is larger than 1 degree of freedom, so it can be used as momentum coupling and distributor. This is get a good expression in hybrid vehicles. In this paper, the planetary gear transmission in the hybrid vehicle as a torque synthesizer discussion and analysis of design. In this paper, the prototype for the Toyota PRUIS planetary gear transmission for the design calculations and simulation of the vehicle. 1) On the basis of the relevant data in the prototype of PRIUS ,it changes to access relevant documentation and determine the parameters of this design and calculation of parameters. 2) Design the transmission parameters in the setting parameters, and check the transmission strength and the lives of the designed parts. 3) Choose the engine and moter through the modeling.
