速比3.7跟4.11哪个省油
推荐回答(5个)
速比3.7和4.11相比3.7省油。速比越小车越快,越省油。速比越大上坡劲越大,费油。但在变速箱不变的前提下,3.7最高速度高但负重能力没有4.11高,4.11可以拉的重一些,且提速比3.7快,但最高速度低于3.7速比。
速比指汽车驱动桥中主减速器的齿轮传动比,它等于传动轴的旋转角速度比上车桥半轴的旋转角速度,也等于它们的转速之比。在一定的行驶条件下,传动系的速比越小,汽车的燃油经济性越高,因此汽车的经济行驶都在高档位。
为了在良好路面条件下以较高车速行驶,轿车在变速器内装置速比小于1的超速档,在车速相同的情况下,挂上超速档可使发动机转速比较低,相对也降低了燃油消耗。传动系的传动比包括变速器各档速比和主减速器比,在良好的道路上行驶选用小速比的主减速器可提高汽车的燃油经济性。
但是,汽车上许多物体都有一个“临界点”问题,过头就会走向反面。主减速器比也是一样,过小就会使最高档的动力性过低,反而会使汽车的燃油经济性变坏,因此一般设计减速器传动比都有一个范围,使得挂直接档时仍有较大的后备功率用于加速或上小坡。
速比3.7和4.11那个快?
3.7要更快一些,但是4.11的扭矩要更大一些。
速比是变速箱每个挡位和汽车上的主减速齿轮都有的,如果速比越大,那传动比就越大,这样车子的轮上扭矩就越大, 但是汽车的速度跑不快。如果速比越小,那传动比也就越小,这样汽车的轮上扭矩是比较小的,但是汽车能跑的很快。
汽车发动机在工作时转速是很高的,所以需要变速箱和主减速齿轮降速增扭,这样汽车才能正常行驶。变速箱的作用是变速变扭,这样输出的动力才能满足汽车在不同工况下的需求。
变速箱每个挡位的速比是固定的,汽车的主减速齿轮的速比也是固定的。建议车友们不要随便更换主减速齿轮,主减速齿轮速比经过汽车厂家的反复测试和工程师的计算,如果更换了,可能会影响汽车的性能。
在平时开车时,起步和超车时要用低速挡,高速巡航时要用高速挡,在上坡或下坡时也需要用低速挡,这样可以利用发动机制动来帮助车辆减速。

不过,特斯拉在发布会上并没有细致地介绍CyberquadATV,有媒体怀疑这可能只是用来展示电动皮卡的载货能力,毕竟它是专为皮卡的6.5英尺卡座而设计的。
但是,这款电动摩托却深受消费者的喜爱,在TravisScott发布的歌曲MV中,还出现了CyberquadATV的原型车。海外很多动手达人甚至亲手打造CyberquadATV,采用类似的全钢板机身设计,不过动力系统与特斯拉原产还是有较大区别。但从中也能看出,大家对这款造型独特的电动摩托车确实很喜欢,奈何该车发布两年都没有要上市的消息。
德龙F3000就是4.111汉德桥,西康385发动机,跑80迈都有点费油
