The invention discloses a stepless speed change transmission device of a tractor. The stepless speed change transmission device comprises a power source, a hydrostatic stepless speed changer, a gearbox assembly, a rear driving assembly, a front driving assembly and a power output assembly. By arranging the hydrostatic stepless speed changer and a space multi-shaft type transmission structure, transverse space is fully utilized, the structure is compact, speed optimization is achieved, the operation is convenient, the agricultural operation rate is improved, meanwhile, a traditional transfer case structure is omitted, the space multi-shaft type structure is utilized, the structure is compact, four-wheel drive is achieved, a transmission belt is adopted for dual-power output, so that the structure is more compact, and raw materials are saved.

    本发明公开了一种拖拉机无级变速传动装置,包括动力源、静液压无级变速器、变速箱总成、后驱动总成、前驱动总成和动力输出总成。本发明通过设置静液压无级变速器加空间多轴式传动结构,充分利用横向空间,结构紧凑,实现了速度的最优化,操纵方便,提高了农业作业率,同时取消传统的分动箱结构,利用空间多轴式结构,结构紧凑,实现四轮驱动,并且采用传动系带双动力输出,结构更加紧凑,节省了原材料等。
