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.
