用塑料板隔离发动机舱,以降低发动机噪声;近几年来不用杠杆式离合器分离机构,而用膜片式分离机构,发动机最大扭矩达2 356N·m的载货汽车都用拉式离合器,变速器档数决定于汽车的装载质量,装载质量越大,档数越多,自动变速器一般均用电子控制;总质量15t以下的汽车用单级主减速器后桥,可用螺旋伞齿轮或双曲线齿轮;用合成材料制成的板簧有许多优点,汽车悬架也得以改进;总质量10t以上的载货车仍用空气悬架,空气元件数量随车型和悬架结构而异;驾驶室的发展方向是改善视野,提高安全性和舒适性。
The use of plastic plates to isolate the engine compartment to reduce engine noise; in recent years without lever clutch release mechanism, and with diaphragm separation mechanism, the maximum torque of the engine up to 2 356N · m are used truck pull clutch, transmission gear The number depends on the loading quality of the car, the greater the loading quality, the more files, the automatic transmission are generally electronically controlled; the total mass of 15t below the vehicle with a single-stage rear derailleur can be used spiral bevel gear or hyperbolic gear; The leaf spring made of synthetic material has many advantages and the automobile suspension is also improved. The air suspension is still used on the truck with a total mass of more than 10 tons. The number of air components varies with the type of the vehicle and the suspension structure. The development direction of the cab Is to improve vision, improve safety and comfort.
