Problems solved by technology

[0004] Since the lifting axle is a load-bearing bridge and has no driving function, in order to ensure sufficient driving force of the vehicle, the axle load of the lifting axle is required to be smaller than the axle load of the drive axle. The prior art uses an additional lifting mechanism in the ordinary ai

Abstract

The invention discloses a heavy truck lifting air suspension system. The heavy truck lifting air suspension system comprises three part, which are a guiding part, a bearing part and a lifting part, wherein the guiding part comprises a guiding bracket, a lower push force rod, an upper push force rod and a crossbeam; the bearing part comprises a lifting axle, a bearing air spring assembly, a locating bracket and a vibration absorber; and the lifting part comprises a lifting air spring, a lifting bracket and a fixed bracket. According to the scheme, as the air lifting spring is connected with the lifting axle through adoption of the locating bracket and the top of the air lifting spring is fixed on the locating bracket, a suspension is lifted through inflating the air lifting spring; as the bottom of the locating bracket is connected with the lower push force rod, the suspension is guided so that the operation direction of the lifting axle is ensured; and meanwhile, as the bearing air spring for bearing body load is also fixed on the locating bracket, guiding, bearing and lifting are combined through adoption of the locating bracket so as to ensure the realization of system functions. The heavy truck lifting air suspension system disclosed by the invention has the advantages of simple structure and high reliability.

Description

technical field [0001] The invention belongs to the field of heavy truck suspension, and in particular relates to a heavy truck lifting air suspension system. Background technique [0002] With the development of the logistics industry and the further deepening of the country's requirements for energy saving and consumption reduction, higher requirements are put forward for the design of commercial vehicles. The lifting suspension system can reduce the friction between the tires and the ground by lifting the lifting axle when the vehicle is unloaded or lightly loaded, so as to achieve the purpose of reducing fuel consumption of the vehicle. In addition, the adoption of the lifting axle can also change the structure of the heavy-duty tractor from a double-axle drive to a single-axle drive + lifting axle, thereby reducing the weight of the vehicle and improving the efficiency of vehicle transportation. [0003] At present, the main lifting suspension system mainly adopts two ...
