About :

Mirosław Romański talks about the cooperation of a railway wheel with a rail. Why won't a train fall off the tracks? In classic wheel sets, the conical profile of the wheel plays a decisive role as a differential mechanism. When travelling on a curve, the wheel set moves transversely to the track axis due to centrifugal force. This causes one wheel to contact the rail with a different diameter than the opposite one, which leads to equalisation of the circumferential speeds of the wheels. Thanks to the conical profile of the wheel surface, the train overcomes curves more easily. This reduces the wear of the wheel treads, because it reduces slippage and stresses resulting from differences in the circumferential speeds of the wheels at contact with the rails when travelling on curves. When the train travels on a straight section, due to the rigid connection of the wheels, the set self-steers in relation to the track axis, because alternately one of the wheels of the set drives the set, and the opposite one brakes it. --------------------------------------------- ✅ If you are interested in receiving notifications about new films, please subscribe to the channel ????
