PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of easily reducing manufacturing costs while having a speed changing function and a steering function, similar to a conventional speed changing function and a conventional steering function.SOLUTION: A traveling vehicle includes: a traveling machine body 1 which is supported by right and left traveling sections 2 a linear hydraulic transmission 53 which comprises a linear hydraulic pump 55 and a linear hydraulic motor 56 a turning hydraulic transmission 54 which comprises a turning hydraulic pump 57 and a turning hydraulic motor 58 and a forced differential mechanism 61 which performs output of the linear hydraulic transmission 53 and output of the turning hydraulic transmission 54 by synthesizing them together. An output control piston 123 or 133 for the hydraulic motor and an output control oil groove 127 or 137 are provided in a housing 53a or 54a of at least either the linear hydraulic transmission 53 or the turning hydraulic transmission 54. Output of the other hydraulic motor 58 or 56 can be controlled on the basis of output of the hydraulic pump 55 or 57 of at least either the linear hydraulic transmission 53 or the turning hydraulic transmission 54.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来と同様の変速機能及び操向機能を持つものでありながら、製造コストを容易に低減できるようにした走行車両を提供するものである。【解決手段】左右の走行部2にて支持される走行機体1と、直進油圧ポンプ55及び直進油圧モータ56を有する直進用油圧変速機53と、旋回油圧ポンプ57及び旋回油圧モータ58を有する旋回用油圧変速機54と、直進用油圧変速機53の出力と旋回用油圧変速機54の出力を合成して出力する強制デフ機構61を備える走行車両において、直進用油圧変速機53または旋回用油圧変速機54の少なくともいずれか一方のハウジング53a,54aに油圧モータ用出力制御ピストン123,133及び出力制御油路127,137を設け、直進用油圧変速機53または旋回用油圧変速機54の少なくともいずれか一方の油圧ポンプ55,57出力に基づき、他方の油圧モータ58,56出力を制御可能に構成したものである。【選択図】図4
