Abstract

The invention discloses a tractor transmission mechanism. The tractor transmission mechanism comprises an auxiliary transmission, a universal joint assembly, a shuttle-type gear shift mechanism, a main transmission and a power output device which are sequentially connected; a front gearbox with a differential mechanism A (15) and connected with the universal joint assembly is arranged between the auxiliary transmission and the universal joint assembly, a rear gearbox with a differential mechanism B (56) and meshed with the main transmission is arranged between the main transmission and the power output device, and walking-wheel mounting flanges are respectively arranged on two sides of the front gearbox and two sides of the rear gearbox. The tractor transmission mechanism has the advantages of being compact in structure, firm and reliable, high in transmission efficiency, convenient in shift, multiple in shift and reasonable in velocity distribution; by the arrangement, a tractor has 12 forward gears, 12 backward gears, quick switching in forward and backward can be realized through an operation lever, gear speed is well matched, and the optimum operation speed can be selected according to specific resistance of different machine tools and different soil.

Description

technical field [0001] The invention relates to a tractor, in particular to a tractor transmission mechanism. Background technique [0002] At present, the existing tractor transmission boxes generally use meshing sleeves to shift gears. This gear shifting method is difficult to shift gears, and the gears are easily damaged during the gear shifting process, and gears are prone to disengagement under heavy loads. Moreover, in the existing tractor gear setting, the number of forward gears is more than that of reverse gears, the gears are set less, the range of speed variation is small, and its high speed is not high enough to adapt to fast transportation; there is only one power output shaft, The power output speed is mostly selected from two gears, which cannot meet the speed requirements of various machines. [0003] In CN2613398Y, disclose the invention patent that name is called " tractor transmission device ". It includes main gearbox, planetary transmission, differenti...
