The invention relates to the technical field of agricultural machinery, in particular to a driving assembly for a tractor and the tractor. The driving assembly for the tractor comprises an engine, a first driving motor, a speed change mechanism, an output transmission shaft and a first planet row. The first planet row comprises three rotating parts which are coaxially arranged, and the three rotating parts are a sun gear, a planet carrier and a gear ring respectively; the engine and the first driving motor are connected with two of the rotating parts respectively, and the input end of the speed change mechanism is connected with the remaining rotating part. According to the driving assembly for the tractor, the first driving motor is matched with the engine, so that when the road condition changes, namely the torque of the engine needs to be changed, the rotating speed of the output transmission shaft is always controlled to be unchanged through the torque output by the first driving motor, and it is guaranteed that the tractor can work normally under any road condition; therefore, the working effect and the working efficiency are ensured.
本申请涉及农业机械技术领域,尤其涉及一种用于拖拉机的驱动总成以及拖拉机。该用于拖拉机的驱动总成包括发动机、第一驱动电机、变速机构、输出传动轴和第一行星排;所述第一行星排包括三个同轴设置的转动件,三个所述转动件分别为太阳轮、行星架和齿圈;所述发动机和所述第一驱动电机分别与其中两个所述转动件连接,所述变速机构的输入端与剩余的一个所述转动件连接。该用于拖拉机的驱动总成,能够利用第一驱动电机和发动机配合,从而实现在路面状况发生变化时,也就是发动机需要变化扭矩时,利用第一驱动电机输出的扭矩,始终控制输出传动轴的转速不变,保证拖拉机能够在任何路面状况下,始终能匀速前进,保证工作效果和工作效率。
