Abstract
(EN)
A wheel set structure, a bogie and a vehicle. The wheel set structure comprises: a rotating shaft (10); a wheel body (20), the wheel body (20) being disposed on the rotating shaft (10); a locking part (40), the locking part (40) being provided with a first position limitedly contacted to the wheel body (20) and a second position spaced with the wheel body (20); a driving assembly (30), the driving assembly (30) and the locking part (40) being actuately connected so as to drive the locking part (40) to move between the first position and the second position. The wheel set structure solves the problem that spring sheets of the existing wheel set structures are easily damaged.

La présente invention porte sur une structure d'essieu monté, sur un bogie et sur un véhicule. La structure d'essieu monté comprend : un arbre rotatif (10) ; un corps de roue (20), le corps de roue (20) étant disposé sur l'arbre rotatif (10) ; une partie de verrouillage (40), la partie de verrouillage (40) étant pourvue d'une première position en contact de manière limitée avec le corps de roue (20) et d'une seconde position espacée du corps de roue (20) ; un ensemble d'entraînement (30), l'ensemble d'entraînement (30) et la partie de verrouillage (40) étant reliés de manière fonctionnelle de sorte à entraîner la partie de verrouillage (40) à se déplacer entre la première position et la seconde position. La structure d'essieu monté résout le problème selon lequel des plaques de ressort des structures d'essieu monté existantes sont facilement endommagées.
