The invention discloses an oil pump box and gearbox transmission structure, a gearbox gear shifting structure and a loader. The oil pump box and gearbox transmission structure comprises an oil pump box, and the interior of the oil pump box is hollow to form a first containing cavity; the working oil pump is arranged on one side of the oil pump box, and at least part of the working oil pump extends into the oil pump box; the steering oil pump is arranged on one side of the oil pump box, and at least part of the steering oil pump extends into the oil pump box; wheels are driven to rotate through the first-stage speed reduction shaft and the second-stage speed reduction shaft through the rotating speed and the torque of the first input gear shaft, different running speeds of a vehicle are achieved, the oil pump box and the gearbox which are integrally formed are stable in structure and convenient to form, and the gear shifting sleeve is driven by the gear shifting driving device to move axially. Free switching between a high-speed gear and a low-speed gear is achieved, a pneumatic mode, a hydraulic mode or an electric push rod mode is adopted, the control mode is simple, operation is easy, and the manufacturing cost is low.

    本发明公开了一种油泵箱和变速箱传动结构、变速箱换挡结构及装载机,包括:油泵箱,所述油泵箱内部中空形成第一容纳腔;工作油泵,所述工作油泵设置于所述油泵箱的一侧,且至少部分延伸至所述油泵箱内;转向油泵,所述转向油泵设置于所述油泵箱的一侧,且至少部分延伸至所述油泵箱内;通过第一输入齿轮轴的转速、转矩,通过一级减速轴和二级减速轴带动车轮转动,实现车辆不同的行驶速度,且通过一体成型的油泵箱和变速箱结构稳固,便于成型,通过换挡驱动装置来驱动换挡套进行轴向移动,实现高速与低速档位的自由切换,而且采用气动方式、液压方式或者电动推杆方式,控制方式简单、容易操作、制造成本较低。
