Track tractor twelve-gear transmission assembly

Abstract

The invention discloses a track tractor twelve-gear transmission assembly. Power is respectively transferred to a rotary cultivation power output shaft part 104 and a walking power driving part 107 through a power input shaft part 101; the clutching and rotating speed adjustment of the rotary cultivation power output shaft part 104 is controlled through a rotary cultivation gear shifting part 102; a driving wheel controls a high-speed gear, a low-speed gear and a reverse gear through a walking high, low and reverse gear shifting part 103; four speed gears are controlled through a walking four-gear shifting part 105; and a walking steering part 106 respectively controls left-right output of the power to realize the steering function. The track tractor twelve-gear transmission assembly has the following advantages: (1) the track tractor twelve-gear transmission assembly can be connected with multiple machine tools on the market, has twelve gears, adopts low walking output, and can arrange various driving track patterns; (2) the rotary cultivation output and the walking are relatively independent; and (3) after the lower power output is applied to a medium-small track tractor, a small load wheel can be adopted.

Description

technical field [0001] The invention relates to a crawler tractor gearbox, in particular to a 12-speed gearbox assembly for a four-sided crawler tractor with a low center of gravity, which can also be used for other special vehicles. Background technique [0002] The crawler transmission scheme is limited by the gearbox assembly, and the walking speed is controlled by the accelerator alone. There are many disadvantages. The speed change of walking and the shift of rotary tillage output sometimes affect each other. At present, the main structural methods used by domestic small and medium-sized crawler tractors are: 1. Triangular rubber crawler type: the driving shaft and engine of the triangular crawler structure are arranged horizontally, the transmission structure is easy to arrange, and the manufacturing cost is low. However, the overall center of gravity of the tractor is relatively high, and the front cutting angle of the track is too small and the passing capacity is ...

AI Technical Summary

Problems solved by technology

However, the overall center of gravity of the tractor is too high, and the front cutting angle of the track is too small and the passing capacity is poor

2. Metal track type: Metal track type track tractors are born out of bulldozers, adopt large road wheel structure, high strength and high manufacturing cost

Neither way is ideal
