汽车加速如何工作

When you hit the gas pedal on your car, there are a number of forces at play to get it going. Here is a basic run-down of what happens when your car accelerates.

油门到发动机

油门踏板是您汽车发动机的直线线。它通过节气门体进行燃油注入或化油器将气流控制进入进气歧管。然后将此空气与燃料混合,由燃油栏和燃料喷油器或化油器喂食,然后用火花塞将其引入火花(例如火花)。这会导致燃烧,这迫使发动机的活塞向下旋转曲轴。随着节气门踏板越来越靠近地板,吸入进气歧管的空气越多,将其与更多的燃料混合在一起,以更快地旋转曲轴。随着曲轴增加的每分钟旋转(RPM)的增加,这是您的引擎“振动”。

引擎到差异

If an engine’s crankshaft output shaft is not connected to anything, it will simply rev and make noise - not acceleration. This is where a transmission comes into play, as it helps transform engine speed into wheel speed. Regardless of whether you have a manual or an automatic transmission, both varieties tap into the engine via an input shaft. Sandwiched between the engine and the transmission is either a clutch for manual transmissions, or a torque converter for automatics. In essence, a clutch and engages the engine from the transmission, while a torque converter maintains the connection but uses a fluid-fed one-way stator and a turbine to eliminate engine stalling when idle. Think of it as a device that is constantly “slipping” the connection between the engine and the transmission.

在变速箱的末端是输出轴,以旋转驱动轴,最终旋转轮胎。在这与输入轴之间,并包装到变速箱外壳中,是您的齿轮。这些增加了输出轴的旋转速度(扭矩)。每个齿轮都是不同的直径,可以增加扭矩但降低输出速度 - 反之亦然。第一和第二档 - 您第一次开始加速时汽车通常会进入的东西 - 大于A 1:1齿轮比,该齿轮比模仿引擎直接连接到轮胎。这意味着您的扭矩会增加以使重型车辆移动,但输出速度降低。当您穿过齿轮时,它们会逐渐变小以提高输出速度。

该输出速度通过连接到差速器的草稿轴传输。通常,这是根据驱动器类型(AWD,FWD,RWD)放在轴或套管中的。

Differential to tires

Your differential connects both drive wheels together, drives the rotation of your tires from the rotation of your transmission’s output shaft, and allows your vehicle to turn smoothly as the left and right tires travel different distances around a corner. It consists of a pinion gear (rotated by the transmission’s output shaft), a ring gear, spider gears that allow different output speeds, and two side gears that are directly connected to the axle shafts that rotate the tires. A differential essentially turns the power flow direction by 90 degrees to rotate the left and right tires. The ring gear acts as a final drive for speed reduction and torque multiplication. The higher the ratio, the lower the top output speed of the axle shafts (i.e. tires), but the higher the torque multiplication.

Why is my car not accelerating?

As you can tell, there are a lot of factors in play to get your car moving, so if yours isn’t accelerating like it should, or not at all, there could be a number of things to blame. For example, if your engine will rev but won’t move the vehicle when in gear, it’s likely that your离合器正在滑动。A engine that stalls will obviously impede acceleration, so make sure you know如何诊断失速引擎。如果您的汽车发生了任何事情,并且您不确定该怎么做,请确保致电我们认证的移动机械师之一,谁将来您的家或办公室诊断和维修您的车辆。万博亚洲客户端Get a quote and book an appointment online或致电1-800-701-6230与服务顾问交谈。
