Question:
I do not know if the train is equipped with a large front-horsepower engine, to drive to have a car, or other device, if the vehicle is driven, then it is much more high-powered engines that can drive it Multi-chassis, it’s time to move any of the mystery of it,

Answer:
landlord, trains and automobiles are not the same drive, car is the engine for power, power through the drive shaft directly to the spread wheel drive car up. vehicle as a result of dead weight \ volume and other restrictions on their own, the engine power would not be significant, large-scale car is more than 300 horsepower.

train now roughly divided into electric locomotive diesel and ordinary diesel locomotives which is a high-power diesel engines, generally 4000-5000 horsepower, there is a large 6000 horsepower, but not directly driven by diesel engine driving the train, the train’s diesel engine is used to generate electricity that is white on electric drive train of. In other words, the front of each train has a traction motor shaft, the main diesel engine driven synchronous generator, and then the supply of electrical Zuogong. ordinary train is not the driving force, all on the front to lead.

electric locomotive is to rely on electric traction, and diesel is different from the front is no longer within a diesel engine and generator, it is the transformer, electric power from the outside world was provided to the traction motor, thus driving the train, it Electric drive is the drive, the same compartment is not the driving force depends entirely on the front to drive. electric locomotive diesel locomotive power in general than the big freight locomotives now is a great power, dual-drive reconnection of 6400 kilowatts of .

There is also a moving car on the group, nicknamed the “bullet” train group DMUs and power train, and their drive is the same as above, but art is the driving force EMU dispersion-type, front and inside are the driving force is the traction motor power source, so that a great power train, the same speed quickly.

There is also a very small number of the diesel hydraulic transmission, not on here. So

landlord, most of the trains are rolling on (the engine) to drive, the reason why the lead locomotive train compartments so much, first because the train tracks on the road, friction and small, very easy to overcome resistance off, Second, because of the continued traction locomotive train a lot, and the car is definitely not this.

hey, the above is quite right to say I have nothing to say.2006-03-24
问题:
我不晓得火车是车头装有一台大马力的发动机，来带动把有车箱呢，还是另有装置，如果就是车头带动的话，那这台发动机得多大马力，能带动那么多机箱，它走动的时候没有什么奥妙之处吗，

回答:
楼主,火车和汽车的传动方式是不一样,汽车是发动机作功,通过传动轴直接把动力传到车轮上来驱动汽车行驶.汽车由于载重量\体积以及自身的其他限制,发动机的功率不会太大,大型汽车也就是300多马力.

火车现在大致分为内燃机车和电力机车,普通的内燃机车车头里面是一台大功率柴油机,一般是4000-5000马力,大的还有6000马力,但是柴油机不是直接驱动火车行驶的,火车的柴油机是用来发电的,说白了火车是靠电传动的.就是说,火车车头的每个轴上都有一部牵引电机,用柴油机带动同步主发电机发电,然后供给电机作功.普通的火车车厢是没有动力的,全是靠车头来带动.

电力机车也是靠电机来牵引,与内燃机车不同之处就是在于车头内不再有柴油机和发电机了,而是大的变压器,通过从外界获得电能提供给牵引电机,从而带动火车行驶,它的传动方式也是电传动,同样车厢也是没有动力的,全靠车头来牵引.电力机车的功率一般要比内燃机车的大,现在货运机车的功率是很大,双机重联的有6400千瓦的.

还有一种就动车组,我们俗称"子弹头",动车组有内燃动车和电力动车,他们的传动方式和上述是一样的,只是先进的动车组是动力分散型的,车头和车厢都有动力,动力来源也是牵引电机,这样火车的功率很大,同样速度就很快.

另外还有极少数液力传动的内燃机车,在这里不再阐述.

所以楼主,大部分的火车都是靠机车(火车头)来牵引的,之所以火车机车能带动那么多车厢,一是因为火车在铁轨上行驶,摩擦力和小,阻力很容易克服掉,二是因为火车机车的持续牵引力很大,而汽车是{jd1}做不到这一点的.
