汽车自动变速箱的运用与维护
摘 要
变速器(transmission)是汽车传动系统的主要组成之一。
汽车的实际使用情况非常复杂，如起步、怠速停车、低速或高速行驶、加速、减速、爬坡和倒车等，这就要求汽车的驱动力和车速能在相当大的范围内变化，而目前广泛采用的活塞式发动机的输出转矩和转速变化范围较小。为了适应经常变化的行驶条件，同时使发动机在有利的工况下(功率较高、油耗较低)工作，在传动系统中设置了变速器.
阐述汽车自动变速箱的组成、工作原理；制动器的组成与工作原理；自动变速器档位的使用更加顺畅；从而达到熟练掌握汽车的目的。日常检测；使汽车寿命更加的延长；从而达到全面保护汽车地目的。下面介绍自动变速的运用与日常维护和体会。

Transmission (transmission) is a major component of automotive transmission system. Actual use of motor vehicles is very complex, such as start, idle stop, slow or high speed, acceleration, deceleration, climbing, and back and on, which requires car drivers and speed can change within a large, but is widely piston engine used in the torque and speed range smaller. To meet the constantly changing driving conditions, while the engine in the favorable conditions (higher power, lower fuel consumption) work, set the transmission in drive. Automatic Transmission set up and working principle; brake components and working principle; the use of automatic transmission gear more smoothly; to achieve the purpose of proficiency in the car. Routine testing; make a more extended life of vehicles; to achieve the objective of comprehensive protection for cars to. Here the use of automatic transmission and experience with routine maintenance.
Keywords: Automotive; transmission; principle; routine maintenance
