變速箱的首要效果
The primary effect of gearbox
1、改變傳動比，以適應不同的行進速度和行進條件；
1. Change the transmission ratio to adapt to different travel speed and conditions.
2、發動機旋轉方向不變情況下，使汽車能倒退行進；
2. When the direction of engine rotation is unchanged, the car can go backwards.
3、使用空擋，中斷動力傳遞，且使發動機停留在怠速的狀況。
3. Use neutral gear, interrupt power transmission, and make the engine stay idle.
以上三點說簡略一點，就是變速箱讓車在不同車速下獲得不同的牽引力。這樣的優點是可以提高引擎的傳動效率。換句話說，就是用更少的油跑更遠的路。
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.
在了解變速箱的結構之前，咱們首先要知道為什么需求變速箱，它的效果是什么。依據不同駕馭狀況，車輛的速度以及動力需求能在一個較大的范圍內進行變化，實現這點，除了有效制動外，擋位的選擇也很重要。
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，改變傳動比來適應不同的駕馭狀況是變速箱的一大效果。此外，實現倒車以及在不熄火狀況下使用空擋切斷動力的傳遞也是變速箱被廣泛應用于內燃機范疇的原因。
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.
手動變速箱
Manual gearbox
“手動擋變速箱并不是低配車型的標志”。這一立場有必要在介紹該類型變速箱之前標明。安裝手動擋變速箱的車型需求駕馭員在駕馭過程中四肢并用來對擋位進行切換，不過有人也把這種與機械直接的交流看作是一種樂趣。
"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.
手動變速箱的優缺點
Advantages and disadvantages of manual transmission
首先，手動擋車型開起來必定不如自動擋車型舒暢，它需求駕馭員支付更多的膂力，當然，也有不少人把這看作為駕馭樂趣，但要是在交通頂峰時期，頻頻的動作也會將這樣的“快感”消磨殆盡。
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".
而它的優勢則在于作業穩定且保養廉價，家用型轎車的手動變速箱除了定時替換手動變速箱油外，離合器的替換算是比較大的保養項目了。
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.
