bent tractor

Abstract

The invention discloses a bowing-type tractor. The bowing-type tractor comprises an engine 1, a transmission box 4, an output shaft 5, a traction shaft 6, a gearbox 7, a transfer case 8, a chassis 9, a manipulation position 10, a wagon box 11, a transmission shaft 15 and a bowing point 17, wherein the engine 1 drives the transmission box 4 through a belt 3; the transfer case 8 is connected with the gearbox 7; the bowing point 17 is arranged in front of the manipulation position 10; the gearbox 7 is arranged at the back of the bowing point 17; the chassis 9 is provided with a traction device 18 which can bow and steer in a balanced way and a universal transmission mechanism which can transmit power; the traction device 18 comprises a front axle 19, a front axle large-beam bracket 22, a transmission shaft 15, a traction shaft 6, a rear axle 14 and a rear axle main large beam 31, wherein the front axle 19 is connected with the chassis 9; steering knuckles 30 are arranged at the two ends of the front axle 19; and the steering knuckles 30 are connected with driving wheels 23 through steering knuckle spindles 29. By the bowing-type tractor, the direction of the tractor is easy to control; the tractor is flexible, lightweight, and high in stability; the steering angle is large; and the tires are not easy to wear.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a folding tractor. Background technique [0002] Walking tractor is a small tractor, which is composed of engine, chassis, electrical system and other systems, and is mainly used for traction and transportation. The power of the walking tractor is driven by the power of the internal combustion engine through the transmission system. The driving wheel that obtains the driving torque then gives the ground a small and backward horizontal force through the tire pattern and the tire surface. It has a simple structure and low power, and is suitable for small-area cultivated land. , the driver holds the armrest to control the operating mechanism, tow or drive the supporting farm implements for operation. [0003] At present, the disc tractors with bending steering mechanism that have been publicly used in the market are generally used in the mountainous or hilly areas. Some new types of bent...

Problems solved by technology

[0007] However, after investigation, it was found that the above disclosed patents still have some defects. Their common shortcomings are: inconvenient operation, low climbing ability, too long vehicle, relatively heavy body, large turning radius, and poor safety performance. And the energy consumption is relatively large, the main reason is that the front axle and the gearbox are integrated, and the engine is on the front axle, so the structure is very complicated, the scope of use and strength are relatively small, and the performance is poor. Brakes and shock absorbers cannot be installed on the bridge, the handling is very complicated and unreliable, and the cost is very high, especially in mountainous or hilly areas, where the ground is uneven, and the front wheels of the tractor will twist due to jumping, lose balance, and even turn. rollover accident

[0009] 1. The bearing of the front axle bracket of this device is connected with the driving wheel. When turning, the whole bracket and the driving wheel rotate at the same time. This shortcoming is particularly serious in the uneven working conditions;

[0010] 2. The universal transmission mechanism adopts long-axis transmission. When turning, the universal joint or universal ball of the long-axis transmission shaft is not in the center of the waist, which can easily cause damage or breakage of the transmission shaft;

[0011] 3. The universal transmission mechanism includes transmission gears, transition gears and gears, which make the mechanism larger and difficult to install and maintain; the more gears, the greater the friction, especially when the speed is increased or decelerated, the power change is the most obvious
