To provide a bogie truck capable of improving comfortableness of passengers when they getting on/off a railway vehicle while taking the fluctuation of a load and abrasion of a wheel into consideration.SOLUTION: A bogie truck includes a) two pairs of wheels (12) in that each pair of wheels (12) are connected to each other by an axle structure (14), b) a continuously-provided truck (18) to which each axle structure (14) is connected through primary suspension means (20), and c) secondary suspension means (22) that is supported by the truck (18) and has at least one leveling valve (26). At least one of the wheels (12) includes an abrasion detection component (30) for the wheel (12) and a link mechanism component (34) arranged between a leveling valve (26) and the abrasion detection component (30). The link mechanism component is suitable for transmitting the displacement of the abrasion detection component to the leveling valve to control the increase/decrease of the pressure inside the secondary suspension means (22).SELECTED DRAWING: Figure 1
【課題】荷重の変動および車輪の摩耗を考慮に入れて乗降車の際の乗客の快適性を向上させるボギー台車を提供すること。【解決手段】ボギー台車は、a)2対の車輪(12)であって、各々の対の車輪(12)が車軸構造(14)によって互いに連結された車輪(12)と、b)連接された車台(18)であって、各々の車軸構造(14)が一次サスペンション手段(20)を通して連結された車台(18)と、c)車台(18)によって支えられた二次サスペンション手段(22)であって、少なくとも1つのレベリングバルブ(26)を具備する二次サスペンション手段(22)とを備え、車輪(12)の少なくとも1つについて、車輪(12)の摩耗検出部品(30)、およびレベリングバルブ(26)と摩耗検出部品(30)との間のリンク機構部品(34)を備え、リンク機構部品は、レベリングバルブに摩耗検出部品の変位を伝達して二次サスペンション手段(22)内の圧力の増減を制御するのに適している。【選択図】図1
