买一套棋牌app需要多少 www.jbqtck.com.cn 如果你駕駛棒移車,那么在你的身上有幾個問題。

如何有趣的“H”模式,我提出這項換檔旋鈕,通過內部的买一套棋牌app需要多少傳動有什么關系呢?什么是移動內部的傳輸,當我移動轉換器?
當我搞砸了,聽到那個可怕的摩擦聲,什么是真正磨?如果我不小心轉移到反向飛馳在高速公路上,而我,會發生什么?整個傳輸會爆炸嗎?

在這篇文章中,我們將回答所有這些問題和我們探討的手動變速器內部。

汽車因為需要傳輸的物理的汽油發動機。首先,任何發動機都有一個紅線 - 一個以上的發動機的^大轉速值不能沒有爆炸。第二,如果你讀過馬力,那么你知道,發動機轉速范圍狹窄,其^大馬力和扭矩分別為。例如,發動機可能產生的^大馬力,在5500轉。傳輸允許的發動機和驅動輪之間的傳動比來改變作為汽車加快和減慢。您換擋,以便引擎可以保持低于紅線附近的轉速帶其^佳性能。

在理想的情況下,傳輸會如此靈活的比例,使發動機始終運行在^高性能的單,RPM值。這是連續可變變速箱(CVT)的背后的想法。

How Manual Transmissions Work

If you drive a stick-shift car, then you may have several questions floating in your head.

How does the funny "H" pattern that I am moving this shift knob through have any relation to the gears inside the transmission? What is moving inside the transmission when I move the shifter?
When I mess up and hear that horrible grinding sound, what is actually grinding? What would happen if I were to accidentally shift into reverse while I am speeding down the freeway? Would the entire transmission explode?

In this article, we'll answer all of these questions and more as we explore the interior of a manual transmission.

Cars need transmissions because of the physics of the gasoline engine. First, any engine has a redline -- a maximum rpm value above which the engine cannot go without exploding. Second, if you have read How Horsepower Works, then you know that engines have narrow rpm ranges where horsepower and torque are at their maximum. For example, an engine might produce its maximum horsepower at 5,500 rpm. The transmission allows the gear ratio between the engine and the drive wheels to change as the car speeds up and slows down. You shift gears so the engine can stay below the redline and near the rpm band of its best performance.

Ideally, the transmission would be so flexible in its ratios that the engine could always run at its single, best-performance rpm value. That is the idea behind the continuously variable transmission (CVT).
