汽车手动变速器六档设置的必要性分析

手动变速器是使用手拨动变速杆改变变速器内的齿轮啮合位置,进而改变传动比,改变发动机传到驱动轮上的转速和转矩,完成原地起步、爬坡、转弯、加速等功能。而六档的设置不仅可以提升换挡和行驶的平顺性、降低汽车的燃油消耗量、提升发动机的使用寿命,还能够更好地适应现代城市道路的实际交通现状和车主高速道路行驶的客观愿望等,因此六档(前进挡)的设置就显得尤为必要。

The Necessity Analysis of Six-speed Setting of Automobile Manual Transmission

The manual transmission uses the shift lever to change the gear meshing position in the transmission,thereby changing the transmission ratio,changing the engine speed and torque transmitted to the driving wheels,and completing functions such as starting on the spot,climbing,turning,and accelerating.The setting of six gears can not only improve the smoothness of shifting and driving,reduce the fuel consumption of the car,and increase the service life of the engine,but also can better adapt to the actual traffi c status of modern urban roads and the objective desire of the owner to drive on high-speed roads and so on.So the setting of sixth gear(forward gear)is particularly necessary.
