The invention relates to the technical field of tractors, in particular to a tractor transmission mechanism and a tractor.The tractor transmission mechanism comprises a power output front section shaft, and the other end of the power output front section shaft is sequentially connected with a first universal joint, a PTO transmission shaft, a power output and input shaft and a power output assembly; the power output front section shaft is sleeved with a shuttle type gear shifting driving gear shaft and a connecting shaft, the PTO transmission shaft is sleeved with a main speed changing input shaft, and one end of the shuttle type gear shifting driving gear shaft is connected with an engine power output shaft through a clutch. The other end of the shuttle type gear shifting driving gear shaft is sequentially connected with a synchronizer, a connecting shaft, a waist twisting middle transmission shaft, a first universal joint and one end of a main variable speed input shaft; one end of the first small bevel gear shaft is in transmission connection with the first differential mechanism, and the other end of the first small bevel gear shaft is sequentially connected with the second universal joint, the second small bevel gear shaft and the second differential mechanism. The device is compact in structure, reduces the occupied space, and has the advantages of high transmission efficiency and convenience in gear shifting.

    本发明涉及拖拉机技术领域,尤其涉及一种拖拉机传动机构以及拖拉机,包括动力输出前段轴,动力输出前段轴的另一端依次连接第一万向节、PTO传动轴、动力输出输入轴、动力输出组件;动力输出前段轴上套接有梭式换挡主动齿轮轴和连接轴,PTO传动轴上套设有主变速输入轴,梭式换挡主动齿轮轴的一端通过离合器与发动机动力输出轴连接,梭式换挡主动齿轮轴的另一端依次连接同步器、连接轴、扭腰中间传动轴、第一万向节、主变速输入轴的一端;第一小圆锥齿轮轴的一端与第一差速器传动连接,所述第一小圆锥齿轮轴的另一端依次连接第二万向节、第二小圆锥齿轮轴、第二差速器。本发明结构紧凑,减少占用空间,具有传递效率高、换挡方便的优点。
