Automatic vertical level-adjusting mechanism for vehicle chassis

Abstract

The invention relates to an automatic vertical level-adjusting mechanism for a vehicle chassis, which belongs to a vehicle travelling system. The automatic vertical level-adjusting mechanism comprises a carriage, a combined rigid body thereof, balancing rods, front connecting rods, rear connecting rods, front supporting rods, rear supporting rods, front wheels, rear wheels and a chassis. As the vehicle chassis travels and operates, the wheels are in contact with the ground for bearing, the front supporting rods and the rear supporting rods respectively move in a manner relative to the carriage, so that the balancing rods make a certain angle with the carriage, and thereby therefore the level of the chassis is vertically and automatically adjusted. As the vehicle chassis travels and operates on the flat ground or the cross slope, the level of the chassis can always be self-adaptively and vertically adjusted, so that the requirements of the crop protection, harvest, transportation and other operation tasks of the agricultural power chassis on a hilly land can be met, and as the chassis travels and operates, the distance between axles and the distance between the wheels are always kept unchanged.

Description

technical field [0001] The invention relates to an automatic adjustment device for the longitudinal level of a vehicle chassis, which belongs to the vehicle running system. In particular, the utility model relates to a chassis for automatically adjusting the longitudinal level of an agricultural vehicle so as to meet the transportation and operation requirements of the agricultural power chassis in hilly and mountainous areas. Background technique [0002] my country's hilly and mountainous areas account for about 2 / 3 of the country's land area, grain production accounts for 1 / 3 of the country's total output, and economic and specialty crops account for more than 50% of the total. They play a decisive role in my country's agricultural production. With the process of urbanization in my country Speeding up, the seasonal shortage of labor force of the right age in hilly and mountainous areas has become increasingly prominent, and labor costs have risen rapidly. Farmers are incre...

AI Technical Summary

Problems solved by technology

At present, my country's hilly and mountainous agricultural power machinery is mainly based on tractors, and its chassis are generally wheeled and crawler-type, mainly including: ordinary tractor four-wheel chassis, crawler chassis, walking tractor and micro-cultivator two-wheel chassis, etc. Equipped with the automatic level adjustment function of the vehicle chassis, it is difficult to meet the requirements of agricultural power chassis in hilly and mountainous areas to complete plant protection, harvesting, transportation and other tasks
