The invention discloses a tractor transmission system and a tractor. The transmission system comprises a clutch assembly, a main and auxiliary speed change assembly, a power take-off device assembly, a four-wheel drive transfer case assembly, a central transmission assembly, a left final transmission assembly, a right final transmission assembly and a power output assembly. The clutch assembly comprises a shuttle gear, the main and auxiliary speed change assembly comprises a main speed change module capable of achieving four-gear adjustment, an auxiliary speed change module capable of achieving four-gear adjustment and a gear shifting mechanism used for adjusting gears of the two speed change modules, and the gear shifting mechanism comprising an inner module and a control tower is arranged in the transmission system. A gear shifting control assembly is shortened in a transmission system, so that the length of a gear shifting control rod cantilever is reduced, under the condition that the rigidity of parts is the same, gear shifting operation is more convenient, abrasion is not prone to occurring, and the service life of all the parts for gear shifting is prolonged; and the independent shuttle-type gear is used for controlling and shifting gears, so that the tractor can turn around under the premise of not changing other gears in actual working conditions, and the complexity of control is reduced.
本发明公开了一种拖拉机传动系统及拖拉机,传动系统包括离合器总成、主副变速总成、取力装置总成、四驱分动箱总成、中央传动总成、左最终传动总成、右最终传动总成和动力输出总成。离合器总成包括梭式档,所述主副变速总成包括能四档调节的主变速模块、四档调节的副变速模块以及用于调节两个变速模块档位的换挡机构,并通过在传动系统中设置包括内模块和塔台的换挡机构,在传动系统内部缩短了换挡控制组件,从而减少了换挡操纵杆悬臂长度,在零部件同等刚度条件下,本发明换挡操作更加方便,不易磨损,增加了换挡用各个零部件的使用寿命;独立的梭式档进行操纵换档,在实际工况时可不改变其它档位的前提下进行拖拉机的调头,减小了操纵的复杂性。
