摘要
The toy railway carriage has three sets of wheels and is able to run on very sharp curves. The sets of wheels are pref. joined in one piece with the undercarriage. The two wheels (4) of the middle set are mounted on their axle (5) so that they can slide inwards. There is a spiral spring (7) enclosing the axle (5) and between the middle wheels (4). This spring lightly presses the wheels (4) outwards against the bearing (2). Between the bearing (2) and wheel (4) is a pref. plastics washer (6).
