The invention relates to the technical field of vehicle suspensions, in particular to an air suspension lifting structure which comprises a lower support, an upper support and a lower support. The upper support is arranged on the inner side of the lower support, pin holes B are formed in the two sides of the upper support, child-mother bushings are arranged in the pin holes B in a sleeved mode, the child-mother bushings comprise the child bushings and the mother bushings, the child bushings and the mother bushings are matched in a sleeved mode, and the child bushings comprise first sleeves and first gaskets integrally formed with one end faces of the first sleeves. The female bush comprises a second sleeve and a second gasket integrally formed with one end face of the second sleeve. The fixing frame is arranged on the inner side of the upper support, and a pin hole C is formed in the fixing frame; the bolt is arranged in the pin hole A, the pin hole C and the first sleeve in a penetrating manner; the upper bracket is clamped between the primary and secondary bushings, so that the problem that the gasket is difficult to center and fix is solved, the mounting process is facilitated, the mounting speed is increased, and the working efficiency is improved; the invention further relates to an assembling method of the air suspension lifting structure.
Description
Technical field: [0001] The application of the present invention relates to the technical field of vehicle suspension, in particular to an air suspension lifting structure, and also to an assembly method of the air suspension lifting structure. Background technique: [0002] The existing semi-trailer lifting mechanism adopts an air suspension, and the axle is lifted or lowered by lifting the air bag: when the vehicle is running without a load, one or two axles are lifted to reduce the friction between the tire and the ground, effectively reducing tire wear and prolonging the life of the vehicle. The service life can reduce the turning radius of the vehicle and reduce fuel consumption; when the vehicle is fully loaded, the lifting axle will automatically drop to ensure the safety of the vehicle. [0003] When the bracket of the existing lift airbag is installed, because the space gap between the upper bracket and the lower bracket, or between the upper bracket and the fixed b...
