Abstract
The invention relates to an automatic transverse level-adjusting mechanism for a vehicle chassis, which belongs to a vehicle travelling system. The automatic transverse level-adjusting mechanism comprises a carriage, a combined rigid body thereof, balancing rods, left connecting rods, right connecting rods, left supporting rods, right supporting rods, left axles, right axles, a chassis, left wheels and right wheels. As the vehicle chassis travels and operates, the wheels are in contact with the ground for bearing, the left supporting rods and the right 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 transversely 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 transversely adjusted, and thereby therefore the requirements of the crop protection, harvest, transportation and other operation tasks of the agricultural power chassis on a hilly land can be met.
