汽車所用的盘形制动在铁路上用得不多,主要原因是铁路車辆比汽車重30～50倍。但是盘形制动有比較良好的制动性能,同时还能减少噪音和振动。西德最近在铁路車辆上采用了盘形制动,試驗成功以后,比利时铁路也在60列两辆一組的列車上装用。在每个車輪上装着一块直徑为700毫米的鋼质 The disc brake used in cars is scarcely used on the railway. The main reason is that railway vehicles weigh 30-50 times more than cars. However, the disc brake has a relatively good braking performance, while reducing noise and vibration. West Germany recently adopted disc brakes on railway vehicles. After the successful test, the Belgian railway was also loaded on 60 trains of two cars. Each wheel is fitted with a 700 mm diameter steel
