Abstract
(EN)
A lubricating structure for a gauge-changeable wheelset and a gauge-changeable wheelset. The lubricating structure comprises wheels (1), an axle (2), and sliding mechanisms. The wheels are slidably disposed at both ends of the axle, the sliding mechanisms are respectively connected to the outer sides of the wheels, and are located in the axle boxes at both ends of the axle, and the wheels are unlocked and locked by the sliding mechanisms. A sealing structure (6) is provided between the inner side of each wheel and the axle, a first cavity (7) is formed among the inner side of the wheel, the axle, and the sealing structure, a second cavity (8) is formed between the outer side of the wheel and the sliding mechanism, and a third cavity (9) is formed between the sliding mechanism and the axle box. The wheel is provided with first oil injection holes (10) leading to the joint between the wheel and the axle, and the axle box is provided with second oil injection holes (11) leading to the sliding mechanism. The lubricating structure can increase the lubrication of a friction surface, reduce the wear of key parts easy to wear, and prolong the overall life of the gauge-changeable wheelset.

L'invention concerne une structure de lubrification pour un essieu monté à jauge variable, et un essieu monté à jauge variable. La structure de lubrification comprend des roues (1), un essieu (2) et des mécanismes coulissants. Les roues sont disposées coulissantes aux deux extrémités de l'essieu, les mécanismes coulissants sont respectivement reliés aux côtés extérieurs des roues, et sont situés dans les boîtes d'essieu aux deux extrémités de l'essieu, et les roues sont déverrouillées et verrouillées par les mécanismes coulissants. Une structure d'étanchéité (6) est disposée entre le côté interne de chaque roue et l'essieu, une première cavité (7) est formée entre le côté interne de la roue, l'essieu et la structure d'étanchéité, une deuxième cavité (8) est formée entre le côté extérieur de la roue et le mécanisme coulissant, et une troisième cavité (9) est formée entre le mécanisme coulissant et la boîte d'essieu. La roue est pourvue de premiers trous d'injection d'huile (10) menant à l'articulation entre la roue et l'essieu, et la boîte d'essieu est pourvue de seconds trous d'injection d'huile (11) menant au mécanisme coulissant. La structure de lubrification peut augmenter la lubrification d'une surface de frottement, réduire l'usure de parties-clé s'usant facilement, et prolonger la durée de vie globale de l'ensemble d'essieu monté à jauge variable.
