Problems solved by technology

However, relying only on the power provided by the rear wheels makes the power of the fifth wheel less when turning. When the soil is soft or the ground is muddy, the wheels are prone to slipping, the turning power is insufficient, the efficiency is low, and the safety performance is poor.

[0021] figure 1 and figure 2 As shown, a tractor multi-gear five-wheel transmission mechanism related to the present invention includes a five-wheel gearbox and a fifth wheel 6 . The five-wheel gearbox includes an input shaft 1, a reverse intermediate shaft 2, an output intermediate shaft 3, a rear output shaft 4 and a front output shaft 5. The rear end of the input shaft 1 is connected to the engine through a clutch. The fifth wheel 6 is mounted on an axle 7 connected to the front output shaft 5 via a universal joint 8 .

[0022] A reverse drive gear 11 , a high-grade drive gear 12 and a low-range drive gear 13 are installed on the input shaft 1 . A reverse intermediate gear 21 meshing with the reverse drive gear 11 is mounted on the reverse intermediate shaft 2 . The rear output shaft 4 is equipped with a shifting driving gear 44 and a reverse driven gear 41, a high-grade driven gear 41, a high-grade driven gear 41, and a high-grade driven gear that are meshed with the ...

[0026] In the second embodiment, except that the third engaging sleeve 52 , the splined hub 56 and the fourth engaging sleeve 53 are different in installation position and function mode, the rest of the structure is basically the same as that of the first embodiment. The difference is that: image 3 As shown, the front end of the rear output shaft 4 and the rear end of the front output shaft 5 are respectively equipped with a spline hub 56, and the third engagement sleeve 52 moves backward to the spline hub at the front end of the rear output shaft 4 56, the connection between the rear output shaft 4 and the front output shaft 5 is disconnected, and when the third engaging sleeve 52 moves forward to the spline hub 56 at the rear end of the front output shaft 5, a part of it It is still engaged with the spline hub 56 at the front end of the rear output shaft 4 , that is, the third engaging sleeve 52 connects the rear output shaft 4 and the front output shaft 5 when moving forwa...

Abstract

The invention relates to the field of transmission devices, in particular to a multi-gear five-wheel transmission mechanism of a tractor. A fifth wheel and a five-wheel transmission are arranged in the tractor. The five-wheel transmission comprises an input shaft, a reverse gear driving gear, a high gear driving gear and a lower gear driving gear. A reverse gear intermediate gear is mounted on a reverse gear middle shaft. A gear shifting driving gear, a reverse gear driven gear, a high gear driven gear and a low gear driven gear are mounted on a back output shaft. A gear shifting driven gear is mounted on a front output shaft, a gear shifting intermediate gear I and a gear shifting intermediate gear II are mounted on an output intermediate shaft, the front end of the back output shaft andthe back end of the front output shaft are connected or disconnected through a third engagement sleeve, and a fourth engagement sleeve linked to the third engagement sleeve is arranged on one side ofthe gear shifting driven gear. The multi-gear five-wheel transmission mechanism is convenient to operate, high in work efficiency and safe and reliable.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a tractor multi-gear five-wheel transmission mechanism. Background technique [0002] As an important agricultural implement, a tractor usually needs to turn at the head of the field when it is mounted with a rear-mounted agricultural tool for operation. However, the four-wheel tractors in the prior art have a large turning radius and low operating efficiency when turning. In view of the above problems, in real work, many people artificially modify the four-wheel tractor, just add a fifth wheel in front of the vehicle, use the lifting device to lift and lower the fifth wheel, when the fifth wheel needs to turn , relying on the driving force of the rear wheels to force the fifth wheel to turn and turn the tractor around. However, only relying on the rear wheels to provide power makes the fifth wheel less powerful when turning. When the soil is relatively soft or the ground is ...
