变速箱的首要效果
The primary effect of gearbox
1、改变传动比，以适应不同的行进速度和行进条件；
1. Change the transmission ratio to adapt to different travel speed and conditions.
2、发动机旋转方向不变情况下，使汽车能倒退行进；
2. When the direction of engine rotation is unchanged, the car can go backwards.
3、使用空挡，中断动力传递，且使发动机停留在怠速的状况。
3. Use neutral gear, interrupt power transmission, and make the engine stay idle.
以上三点说简略一点，就是变速箱让车在不同车速下获得不同的牵引力。这样的优点是可以提高引擎的传动效率。换句话说，就是用更少的油跑更远的路。
Above three points to say briefly, is that the gearbox allows the car to obtain different traction at different speeds. The advantage of this method is that it can improve the transmission efficiency of the engine. In other words, it's running farther with less oil.
在了解变速箱的结构之前，咱们要知道为什么需求变速箱，它的效果是什么。依据不同驾驭状况，车辆的速度以及动力需求能在一个较大的范围内进行变化，实现这点，除了有效制动外，挡位的选择也很重要。
Before we understand the structure of the gearbox, we first need to know why the gearbox is needed and what its effect is. According to different driving conditions, vehicle speed and power demand can be changed in a larger range. To achieve this, besides effective braking, gear selection is also very important.
所以，改变传动比来适应不同的驾驭状况是变速箱的一大效果。此外，实现倒车以及在不熄火状况下使用空挡切断动力的传递也是变速箱被广泛应用于内燃机范畴的原因。
Therefore, changing the transmission ratio to adapt to different driving conditions is a major effect of the gearbox. In addition, reversing and using neutral cut-off power transmission under non-extinguishing conditions are also the reasons why gearboxes are widely used in the field of internal combustion engines.
手动变速箱
Manual gearbox
“手动挡变速箱并不是低配车型的标志”。这一立场有必要在介绍该类型变速箱之前标明。安装手动挡变速箱的车型需求驾驭员在驾驭过程中四肢并用来对挡位进行切换，不过有人也把这种与机械直接的交流看作是一种乐趣。
"Manual gearbox is not a sign of low-matching models". This position needs to be marked before introducing this type of gearbox. Vehicle models with manual gearboxes require drivers to use their limbs to switch gears during steering, but some people also regard this direct communication with machinery as a pleasure.
手动变速箱的优缺点
Advantages and disadvantages of manual transmission
，手动挡车型开起来必定不如自动挡车型舒畅，它需求驾驭员支付更多的膂力，当然，也有不少人把这看作为驾驭乐趣，但要是在交通顶峰时期，频频的动作也会将这样的“快感”消磨殆尽。
First of all, manual gear is not as comfortable as automatic gear. It requires drivers to pay more effort. Of course, many people regard it as driving pleasure, but if it is in the peak period, frequent actions will wipe out such "pleasure".
而它的优势则在于作业稳定且保养廉价，家用型轿车的手动变速箱除了定时替换手动变速箱油外，离合器的替换算是比较大的保养项目了。
Its advantage lies in stable operation and low maintenance. Besides replacing manual transmission oil regularly, the replacement of clutch is a relatively large maintenance project.
