Problems solved by technology
[0002] At present, the power of the rear PTO shaft is drawn from the front end of the two shafts in the rear PTO gearbox used for tractors, and the front end of the two shafts forwards the power to the longitudinal transmission shaft through two-stage gear meshing. , and then the power is transmitted from the longitudinal drive shaft to the rear power output shaft. In this way, the rear output of power is realized. The box body must be lengthened, the longitudinal drive shaft must be lengthened, and the number of gears will also increase. Therefore, not only the manufacturing cost High, more importantly, it increases the power consumption inside the gearbox and reduces the transmission efficiency of the gearbox
In general, for example, the Taishan series four-wheel tractor gearbox has six forward gears and one reverse gear. With the increase in the types of supporting agricultural machinery, it is difficult for users to choose a reasonable working speed according to different operating requirements and loads, thereby increasing Reduce fuel consumption and affect the improvement of the overall performance of the tractor

Embodiment Construction
[0017] For the convenience of description, in Figure 1, figure 2 and image 3 In the illustrated embodiment, when the gearbox is placed horizontally, the part close to the first axis 1 is defined as the front side, and the part away from the first axis 1 is defined as the rear side.
[0018] A rear power output gearbox of a transverse tractor, which includes a shaft 1 for inputting power, and multiple transverse transmission shafts for transmitting power to driving wheels, and these transverse transmission shafts include two shafts 2 and three shafts 3 , four shafts 4, five shafts 5 and six shafts 6, the rear PTO shaft 9 is installed on the rear portion of the gearbox, and the longitudinal drive shaft 8 installed inside the gearbox casing 10 is parallel to the rear PTO shaft 9.
[0019] The front end of the longitudinal transmission shaft 8 is provided with a first bevel gear 81, which is directly meshed with the second bevel gear 11 fixed on the first shaft 1, and the bevel ...

The invention relates to a transverse connecting tractor back power output gear box, characterized in that the front end of the longitudinal transmission axle is meshed with an axle gear while the back end is meshed with a back power output axle gear, the power of the back power output axle is transmitted from the first axle, the first gear to the longitudinal transmission axle, therefore, the invention can shorten the lengths of box and longitudinal transmission axle, reduce cost and power consumption and improve transmission efficiency of gear box. When a backward shift is arranged between the second and the third axles, the high-low shift gears can realize two backward shift outputs. The invention can output six forward shifts and two backward shifts, with selective working speeds via different loads.
Description
technical field [0001] The invention relates to the technical field of gearboxes, in particular to a transversal multi-gear rear power output gearbox for tractors. Background technique [0002] At present, the power of the rear PTO shaft is drawn from the front end of the two shafts in the rear PTO gearbox used for tractors, and the front end of the two shafts forwards the power to the longitudinal transmission shaft through two-stage gear meshing. , and then the power is transmitted from the longitudinal drive shaft to the rear power output shaft. In this way, the rear output of power is realized. The box body must be lengthened, the longitudinal drive shaft must be lengthened, and the number of gears will also increase. Therefore, not only the manufacturing cost High, more importantly, it increases the power consumption inside the gearbox and reduces the transmission efficiency of the gearbox. In general, for example, the Taishan series four-wheel tractor gearbox has six ...
