Abstract
(EN)
A seated part 13 of an air spring 10 has a first contact part 19, a first opposing surface 20, and a shaft part 14. A spring support part 30 had a second contact part 31 that comes into contact with the first contact part 19 in a seated state, a second opposing surface 32 that is set apart from and that opposes the first opposing surface 20, a shaft insertion hole 33, and a shaft-movement-restricting part 34 protruding from the second opposing surface 32 so as to section off a shaft insertion space 35 that communicates with the shaft insertion hole 33. The shaft part 14 is inserted through the shaft insertion hole 33 and the shaft insertion space 35 in the seated state. The tip end of the shaft part 14, which withdraws from the shaft insertion hole 33 due to the rising of an upper structure from the seated state, moves through the shaft insertion space 35. The tip end of the shaft part 14 withdrawn from the shaft insertion hole 33 enters the shaft insertion hole 33 from the shaft insertion space 35 due to the lowering of the upper structure to the seated state.

Une partie assise (13) d'un ressort pneumatique (10) comporte une première partie de contact (19), une première surface opposée (20), et une partie arbre (14). Une partie support de ressort (30) a une seconde partie de contact (31) qui vient en contact avec la première partie de contact (19) dans un état assis, une seconde surface opposée (32) qui est espacée de et qui est opposée à la première surface opposée (20), un trou d'insertion d'arbre (33), et une partie de restriction de mouvement d'arbre (34) qui fait saillie depuis la seconde surface opposée (32) de façon à couper un espace d'insertion d'arbre (35) qui communique avec le trou d'insertion d'arbre (33). La partie arbre (14) est insérée à travers le trou d'insertion d'arbre (33) et l'espace d'insertion d'arbre (35) dans l'état assis. L'extrémité de pointe de la partie arbre (14), qui se retire du trou d'insertion d'arbre (33) en raison de l'élévation d'une structure supérieure à partir de l'état assis, se déplace à travers l'espace d'insertion d'arbre (35). L'extrémité de pointe de la partie arbre (14) retirée du trou d'insertion d'arbre (33) pénètre dans le trou d'insertion d'arbre (33) à partir de l'espace d'insertion d'arbre (35) en raison de l'abaissement de la structure supérieure vers l'état assis.

エアスプリング10の着座部13は、第1当接部19と第1対向面20と軸部14とを有する。スプリング支持部30は、着座状態で第1当接部19と当接する第2当接部31と、第1対向面20から離間して対向する第2対向面32と、軸挿通孔33と、軸挿通孔33と連通する軸挿通空間35を区画するように第2対向面32から突出する軸移動規制部34とを有する。軸部14は、着座状態で軸挿通孔33及び軸挿通空間35を挿通する。着座状態からの上構造体の上昇により軸挿通孔33から抜けた軸部14の先端は、軸挿通空間35を移動する。軸挿通孔33から抜けた軸部14の先端は、着座状態への上構造体の下降により軸挿通空間35から軸挿通孔33へ進入する。
