Gearbox of agricultural vehicle and agricultural vehicle with gearbox

Abstract

The invention provides a gearbox of an agricultural vehicle. The gearbox of the agricultural vehicle comprises a driving shaft, driven shafts on the two sides of the driving shaft, a main box body arranged on the driving shaft, and edge reduction box bodies arranged on the two sides of the main box body and connected with the driving shaft and the driven shafts. The main box body is arranged in the middle position of the agricultural vehicle and comprises two first driving gears which are arranged on the driving shaft. Each edge reduction box body comprises a second driving gear arranged on the driving shaft and an edge reduction gear arranged on the corresponding driven shaft and engaged with the second driving gear. The second driving gears and the first driving gears are arranged in a linkage mode. At least the edge reduction box body on one side of the main box body deviates from the main box body towards traveling mechanisms of the driven shafts. According to the gearbox of the agricultural vehicle, the minimum distance between the middle position where soil is prone to being accumulated and the ground is greatly increased, and thus soil is not prone to being accumulated anymore; and meanwhile, the space defined by the inner sides of the two edge reduction box bodies and the bottom of the main box body is enlarged, so that soil and the like discharged by a traveling mechanism of the vehicle are not prone to being accumulated in the space, and advancing resistance of the vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a gearbox for agricultural vehicles and an agricultural vehicle with the same. Background technique [0002] The gearboxes of current tracked agricultural vehicles are generally integral or close to the main box, with one side added and one box removed. [0003] Such as figure 1 It shows an integral gearbox, which includes a box body 1, a driving shaft 2, a driven shaft 3, two double gears 4 mounted on the driving shaft 2, and two side reduction gears mounted on the driven shaft 3 5. The driving shaft 2, two double gears 4 and two side reduction gears 5 are installed in the box 1, the first end of the double gear 4 rotates under the drive of the engine, and the second end is connected with the corresponding side reduction gears. 5 meshes, the engine drives the driven shaft 3 to rotate through the duplex gear 4, and then the vehicle runs. Due to the use of the dual gear 4 an...

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect that a large amount of soil is accumulated in front of the gearbox main box when the crawler agricultural vehicle in the prior art is working in deep mud, which hinders the vehicle from moving forward, thereby providing a When working in deep mud, a large amount of soil will not accumulate in front of the main box of the gearbox, so that the gearbox of the agricultural vehicle and the agricultural vehicle with it will not hinder the forward movement of the vehicle
