Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, a large tractor transfer case of the present invention includes an input shaft 1, a rear axle output shaft 10, and a front axle output shaft 17 installed in the housing assembly 9 sequentially from top to bottom.

[0016] The input shaft 1 is supported on the housing assembly 9 through cylindrical roller bearings 2 and 24, and the high-grade input gear 3, the middle-range input gear 4, the low-range input gear 5, and the reverse gear 6 are respectively emptied on the input shaft 1 through needle bearings. Upper: High-grade input gear 3, middle-range input gear 4, low-range input gear 5, and reverse gear 6 are respectively equipped with meshing sleeve shift mechanisms, and the splines through which the high- and low-range gear holders 21 pass are fixed on the input shaft 1. Middle gear, reverse gear gear seat and input shaft 1 are made into one. The rear axle output shaft 10 is supported on the housing assembly 9 through cylindric...

Abstract

The invention discloses a transfer case of a large tractor, which belongs to the technical field of agricultural machinery transmission parts. A high-gear input gear, a medium-gear input gear, a low-gear input gear and a reverse-gear input gear are hollowly sleeved on an input shaft, a high-low gear shifting gear block is fixed onto the input shaft through a spline, a brake mounting support is fixed onto a shell component, and a brake disc is fixed onto the input shaft. A high-gear output gear, a medium-gear output gear, a low-gear output gear and a reverse-gear output gear are fixed onto a rear axle output shaft, wherein the high-gear output gear, the medium-gear output gear and the low-gear output gear are engaged with the high-gear input gear, the medium-gear input gear and the low-gear input gear respectively. A front axle output gear is hollowly sleeved on a front axle output shaft and engaged with the high-gear output gear. A reverse-gear idle gear is supported on the shell component through a reverse-gear idle gear shaft, and is simultaneously engaged with the reverse-gear input gear and the reverse-gear output gear on the rear axle output shaft. The transfer case is compact in structure, wide in speed ratio range, fine in meshing performance, low in cost and convenient in maintenance, has multiple gears, and can be matched with a 180-220 horsepower engine.

Description

technical field [0001] The invention discloses a large-scale tractor transfer case, which belongs to the technical field of agricultural machinery transmission parts. Background technique [0002] At present, the transfer case of domestic split combined high-power tractors has a structure of two forward gears and one reverse gear. In order to further improve the efficiency of the engine within the power range and meet the operating requirements of the tractor, it is necessary to develop a transfer case with more gears. At the same time, as the horsepower of the engine increases, the structure of the parking brake installed on the transmission is difficult to meet the development needs of high-power tractors due to the constraints of the overall structure of the transmission and the space size of the tractor. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide a compact structure, multiple gea...
