Small triangular crawler chassis applicable to hilly and mountainous regions

Abstract

The invention relates to a small triangular crawler chassis applicable to hilly and mountainous regions. The small triangular crawler chassis comprises a frame, triangular crawler traveling mechanismsand steering mechanisms, the triangular crawler traveling mechanisms are positioned on two sides of a front axle and a rear axle on the lower portion of the frame, the steering mechanisms are positioned among the rear axle and the triangular crawler traveling mechanisms, the triangular crawler traveling mechanisms comprise crawlers, supports, driving wheels, guide wheels, tension wheels and loading wheels, the driving wheels are connected onto the supports, the guide wheels and the tension wheels are connected to two ends of the lower portions of the supports, the loading wheels are connectedto the lower portions of the supports and positioned among the tension wheels and the guide wheels, the crawlers surround the driving wheels, the guide wheels, the loading wheels and the tension wheels, dampers II and damping springs II are arranged among the tension wheels and the supports, and horizontal dampers I and damping springs I are arranged on the lower portions of the supports. According to the chassis, a sensor is combined with a lifting cylinder, the attitude of the chassis is manually or automatically leveled, multi-aspect damping is realized by the aid of the bidirectional dampers and the damping springs, and the whole chassis has higher passing ability, stability and smoothness.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small triangular crawler chassis suitable for hilly and mountainous areas. Background technique [0002] The crawler chassis is widely used in the field of agricultural production and harvesting due to its high land passability and low ground pressure. However, due to the poor working environment and harsh working conditions, tracked vehicles often face problems such as large vibration and shock, high center of gravity, and poor stability, which are not conducive to production and harvest. Traditional crawlers mostly use friction damping methods to eliminate the impact of the ground, and even many agricultural vehicles do not perform vibration damping, but traditional friction damping does not completely consume vibration and impact, and there is a large amount of vibration that is transmitted to the machine through the impact of the frame And on the driver, the...

Problems solved by technology

However, due to the poor working environment and harsh working conditions, tracked vehicles often face problems such as large vibration and shock, high center of gravity, and poor stability, which are not conducive to production and harvest.

Traditional crawlers mostly use friction damping methods to eliminate the impact of the ground, and even many agricultural vehicles do not perform vibration damping, but traditional friction damping does not completely consume vibration and impact, and there is a large amount of vibration that is transmitted to the machine through the impact of the frame And the driver's body, the comfort effect is very poor, and the ride comfort is not good

For agricultural machinery operators who work for a long time, they are prone to fatigue

And when the tracked vehicle is driving on uneven and sloped roads, due to the high center of gravity and the heavy weight of the whole machine, the problem of rollover is prone to occur during work and has been urgently needed to be solved.
