Distance-Recording Vehicle 中国记里鼓车
Have you ever thought about how ancient people calculated the mileage of cars? Let's take a look together today!
你有想过古人是怎么计算车的里程吗？今天我们一起来看看吧。
Distance-Recording Vehicle was used to calculate mileage in ancient China. It dated back to the Wei and Jin periods about 1.700 years ago (220AD-420AD).
记里鼓车是中国古代用于计算道路里程的车。其发明年代大约可追潮至距今1700多年的魏晋时期。
It was a "sister vehicle" of the South-Pointing Chariot. They both were ceremonious vehicles and put in the forefront of the imperial procession side by side.
记里鼓车是指南车的姊妹车，两辆车作为天子出行时的仪仗车，并排行驶在仪仗队伍的最前列。
This chariot has two wooden figures which hit the drum once after every 500 meters are covered. That is the origin of its name.
记里鼓车上有两个木人，因设有行一里路而击一次鼓的装置故名记里鼓车。
It has a single shaft and double wheel, with the distance-recording function is completed by the reduction gear system inside the car. The system consists of attached gears mounted on the wheels, the lower flat gear and the whirlwind gear fixed on one axle, and the middle flat gear and the cam tap on the other axle.
记里鼓车的外形为独辕双轮车，其计程功能是由车内的减速齿轮系统完成的，该系统由固定在车轮上的附足立齿轮、固定在同一根轴上的下平轮与旋风轮、固定在同一根轴上的中平轮与凸轮拨子构成。
When the chariot is driving, the wheels start to rotate, and all the gears are rotated by mutual meshing. When the chariot drives 500 meters, the last gear axis completes a full rotation and the cam tap on the gear axis lifts the rope linked with the arm of the wooden figure to make it hit the drum once to record the distance covered.
当车辆行驶起来的时候，车轮开始转动，所有齿轮通过相互啮合传递动力转动起来，其最末一根齿轮轴在车行一里时正好回转一周，齿轮轴上的凸轮拨子牵动连接木人上臂的绳索，拉动木人击鼓一次，以示里程。
The Distance-Recording Chariot can be regarded as the predecessor of the odometer and reduction gear, representing a major scientific breakthrough.
可以说记里鼓车是现代汽车里程表、减速器的先驱，是科学技术史上的一项重大成就。
If you are interested in this, you can see how wheels and wooden figures cooperate in the Beijing Auto Museum.
如果您对此感兴趣，可以在北京汽车博物馆直观感受具体车轮与木人的默契配合。
