PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of reducing components costs and assembling man-hours, control man-hours or the like in a manufacturing line, while it can inhibit a traveling machine body from moving due to an erroneous driving operation.SOLUTION: A traveling vehicle includes: a traveling machine body 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. The traveling vehicle has a structure which is configured to make output of the turning hydraulic motor 58 changeable. An output control mechanism of the turning hydraulic motor 58 is connected to an output control mechanism of the linear hydraulic pump 55, and the output of the turning hydraulic motor 58 is changed in such a manner as to interlock with a change in output of the linear hydraulic pump 55.COPYRIGHT: (C)2013,JPO&INPIT【課題】操縦操作の誤操作による走行機体の移動を阻止できるものでありながら、部品コストや、製造ライン中での組付け工数又は調節工数等を低減できるようにした走行車両を提供しようとするものである。【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、旋回油圧モータ58の出力を変更可能に構成する構造であって、直進油圧ポンプ55の出力制御機構に旋回油圧モータ58の出力制御機構を連結させ、直進油圧ポンプ55の出力変更に連動して、旋回油圧モータ58の出力が変化するように構成するものである。【選択図】図3
