The invention provides a gearbox, a haunch-type mobile platform and a vehicle, and the gearbox has a forward/backward switching function, a first-stage high and low speed switching function, a second-stage I/II high and low gear switching function and five output shafts, and the five output shafts are used for driving wheels, tracks and PTO external equipment of the haunch-type mobile platform respectively. The chassis is simple in structure, complete in function and capable of meeting the driving requirement of a haunch type mobile platform, the chassis can have four plus four gears of advancing and retreating through permutation and combination of the front-rear gear sliding sleeve, the high-low gear sliding sleeve and the I/II gear sliding sleeve at different positions of respective shafts, and the requirement for the operation speed in different scenes can be met; a brake mechanism is arranged in the gearbox and can be used for braking a single-side wheel and a crawler belt, so that in-situ steering is realized; the PTO high-low gear switching mechanism can switch the high-low gear rotating speed of the PTO output shaft.
本发明提供了一种变速箱、拱腰式移动平台及车辆,具备前进/后退切换、一级高低速切换、二级Ⅰ/Ⅱ高低档切换以及5个输出轴,5个输出轴分别用于驱动拱腰式移动平台的车轮、履带以及PTO外挂设备,功能全面且能够满足拱腰式移动平台的驱动需求,通过前后档滑移套、高低档滑移套和Ⅰ/Ⅱ挡滑套套在各自轴上的不同位置的排列组合,可以使得底盘共有前进、后退4+4个档位,能满足其不同场景中作业速度的需要;变速箱内部设有制动机构,可以对单侧车轮及履带进行制动,实现原地转向;通过PTO高低档切换机构可以切换PTO输出轴的高低档转速。
