Articulated tractor

Abstract

The invention discloses an articulated tractor which comprises an engine, a transmission box, a traction shaft, a speed changing box, a transfer box, a chassis, an operation position, a vehicle box, a drive shaft and an articulation point, wherein the engine is in belt drive with the transmission box, and the transfer box is connected with the speed changing box. The articulated tractor is characterized in that an articulation point of the tractor is arranged in front of the operation position, the speed changing box is arranged behind the articulation point, the traction shaft has a solid structure or a hollow structure, the chassis is provided with a traction bracket device which can be articulated and can balance in a steering way, a front axle and / or a rear axle with the functions of damping and braking and an universal transmission mechanism which can transmit the power at a long distance; and the front axle is separated from the speed changing box. The articulated tractor has the characteristics of being simple in structure, low in cost, reliable in operation, safe, durable, wide in adaptability, flexible to steer, high in work efficiency, wide in use, high in carrying capacity, and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a speed-controlled bending-steering tractor with a single gearbox whose bending point is in front of the control position and the gearbox is behind the bending point. Background technique [0002] Walking tractors occupy a pivotal position in my country's agricultural machinery market, especially the advent of industrial and agricultural-12-type walking tractors, which are used for short-distance transportation most of the time except for farmland operations during busy farming seasons. One of the means of transportation, but walking tractors have disadvantages such as low speed, high fuel consumption, and poor steering safety during transportation. Therefore, since the 1980s, various walking tractor factories have successively developed on the basis of walking tractors. The bent-over steering transport vehicle has high transport efficiency, is more fuel-efficient, and the steering operat...

Problems solved by technology

[0006] However, after the inventor's market research, it is found that the above disclosed documents also have some defects, and their common shortcomings are: inconvenient operation, low climbing ability, too long vehicle body, heavy body, large turning radius, and safety. The performance is poor, and the energy consumption is high, 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. Moreover, brakes and shock absorbers cannot be installed on the front axle, 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 and lose balance. It can even lead to excessive turning and cause rollover accidents

Therefore, the above defects have become the technical bottleneck of the tractor industry
