Travel drive device
A travel drive device (13) for a bulldozer (1) having a speed reducer (22) is provided with an output shaft (23), a sprocket hub (71), a housing (24), and a floating oil seal (27). The output shaft (23) outputs driving force from the speed reducer (22). The sprocket hub (71) has an inner surface portion (71a) disposed on the speed reducer (22) side, and is connected to the output shaft (23). The housing (24) has an outer surface section (62b) facing the inner surface section (71a), and covers the sprocket hub (71) side of the decelerator (22). The floating oil seal (27) is formed between the inner surface portion (71a) and the outer surface portion (62b), and is disposed at an end portion of a space (S) filled with lubricating oil.
行驶驱动装置（13）为具有减速器（22）的推土机（1）的行驶驱动装置（13），具有：输出轴（23）、链轮轮毂（71）、壳体（24）、以及浮动油封（27）。输出轴（23）从减速器（22）输出驱动力。链轮轮毂（71）具有在减速器（22）侧配置的内表面部（71a），并与输出轴（23）连接。壳体（24）具有与内表面部（71a）对置的外表面部（62b），覆盖减速器（22）的链轮轮毂（71）侧。浮动油封（27）形成在内表面部（71a）与外表面部（62b）之间，并配置在填充润滑油的空间（S）的端部。
