Triangular speed-increasing chassis and operating vehicle

Abstract

The invention discloses a triangular speed-increasing chassis which comprises a caterpillar band, a caterpillar band support, a driving wheel arranged on the inner side of the caterpillar band, a driving disc and a driven disc, the caterpillar band support is arranged on the inner side of the caterpillar band, and the driving wheel drives the caterpillar band to roll; the driving disc is driven by an external driving mechanism; the driven disc is meshed with the driving disc and is used for driving the driving wheel to rotate; the tooth number Z1 of the driving disc is larger than the tooth number Z2 of the driven disc, so that the rotating speed n2 of the driven disc is larger than the rotating speed n1 of the driving disc, and the rotating speed of the driving wheel is increased. The working vehicle is included and comprises a steering device with steering wheels, a crawler device with the triangular speed-increasing chassis, and a connecting device for connecting the steering device with the crawler device. The steering device of the working vehicle is provided with the steering wheels to guarantee that the steering device still adopts a wheel type, so that the turning radius is not changed, the steering device serves as a crawler device of rear wheels, a tractor can walk on muddy, hollow and other complex terrains, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a delta speed-increasing chassis and a work vehicle including the delta speed-increasing chassis. Background technique [0002] Tractors with both front and rear wheels are prone to slipping in muddy or swampy terrain when working in the field, and the tires are easy to sink into pits when encountering potholes and uneven terrain, so wheeled tractors are not suitable for complex field terrain. Therefore, the wheeled tractor is transformed, and the front and rear four wheels are all triangular crawler tractors. However, compared with the wheeled tractor, although it can solve the problem of being suitable for complex terrain, this kind of tractor with three-wheeled triangular track still has many problems. For example, the turning radius of the front triangular track wheel is too large, which makes it difficult for the driver to work. , it is more prone to fatigue after long-term work; the radius of the refitted driving wheel ...

AI Technical Summary

Problems solved by technology

However, compared with the wheeled tractor, although it can solve the problem of being suitable for complex terrain, this kind of tractor with three-wheeled triangular track still has many problems. For example, the turning radius of the front triangular track wheel is too large, which makes it difficult for the driver to work. , it is more likely to be fatigued after long-term work; the radius of the drive wheel after modification becomes smaller, resulting in a decrease in working speed, which greatly affects work efficiency

In addition, after refitting the front and rear four wheels into a triangular crawler type, the weight of the tractor body will inevitably increase, making the tractor's load too large, increasing fuel consumption, and resulting in increased fuel consumption costs

[0003] In addition, the triangular crawler adopts the chain transmission method, but the chain transmission has unstable chains and is easy to loosen, and its durability is not enough and the service life is not high.
