The invention discloses a gearbox flexible shaft arrangement structure and a commercial vehicle, and belongs to the field of vehicles. According to the technical scheme, the gearbox flexible shaft assembly arrangement structure comprises a flexible shaft assembly, and a first fixing point and a second fixing point are arranged on the two sides of the bottom face of a cab bottom plate respectively; a third fixing point and a fourth fixing point are arranged on one frame longitudinal beam; the flexible shaft assembly is sequentially fixed to the first fixing point, the second fixing point, the third fixing point and the fourth fixing point. According to the scheme, the flexible shaft assembly is arranged to be in the L shape, the front section of the flexible shaft assembly is transversely arranged on the front portion of the bottom face of the cab bottom plate, namely the position close to the cab overturning shaft, then the front section of the flexible shaft assembly extends to the gearbox assembly along the longitudinal beam of the frame, the flexible shaft is close to the overturning shaft when the frame is overturned, the needed expansion amount is small, and the needed length of the flexible shaft is shortened; meanwhile, the area, close to the edge, of the cab bottom plate is more attractive, interference with other parts is smaller, free movement of the cab bottom plate is limited, the cab bottom plate is strictly located at the arrangement position, and transmission efficiency is guaranteed.
本发明为一种变速箱软轴布置结构及商用车,属于车辆领域。其技术方案为,一种变速箱软轴组件布置结构,包括软轴组件,驾驶室底板的底面两侧分别设有第一固定点和第二固定点;一条车架纵梁上设有第三固定点和第四固定点;软轴组件依次固定于第一固定点、第二固定点、第三固定点和第四固定点。本方案将软轴组件布置为L形,软轴组件前段横向布置于驾驶室底板底面前部,即靠近驾驶室翻转轴的位置,然后沿车架纵梁走向变速箱总成,在车架翻转时软轴靠近翻转轴位置,所需伸缩量小,缩短了软轴的所需长度,同时位于驾驶室底板靠近边缘的区域,更加美观,与其他部件干涉更小,且限制了其自由活动,严格位于布置位置,保证了传动效率。
