Description
図1は、第1実施形態に係る鉄道車両の台車1の側面図である。図1に示すように、鉄道車両の台車1は、空気バネ2を介して車体50を支持する台車枠3を備える。台車枠3は、車幅方向両側において車両長手方向に延びた一対の側梁4と、一対の側梁4を互いに連結して車幅方向に延びた横梁(図示せず)とを有し、平面視でH形状を呈する。台車枠3の車両長手方向の両側には、車幅方向に沿って延びた車軸6が配置されている。車軸6の車幅方向両側の部分には、車輪7が夫々固定されている。車軸6の車幅方向の両端部には、車輪7よりも車幅方向外側にて車軸6を回転自在に支持する軸受8が設けられている。軸受8は、内輪(図示せず)と、外輪8a(図2参照)と、内輪と外輪8aとの間に挟まれた転動体(図示せず)とを有する。軸受8は、軸箱11に収容されている。
図7は、第2実施形態に係る台車の要部を一部断面化した側面図である。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。第1実施形態では、輪軸支え17と軸箱本体16とは、それぞれ別部材としたが、第2実施形態では、それらを一体構造としている。図7に示すように、第2実施形態の軸箱111は、一体に成形された筒状体であり、軸梁12も軸箱111に一体化されている。軸受温度検出装置110は、温度センサユニット20、弾性装置21、温度センサユニット支持座22及び軸箱111を備える。軸箱111は、軸受8の外輪8aの外周面の上領域を覆う軸箱上部116と、軸受8の外輪8aの外周面の下領域を覆う軸箱下部117とを有する。
