The invention relates to a lightweight air chamber bracket of a vehicle. The air chamber bracket is integrally formed in a casting manner and comprises a main pin bearing seat, a camshaft bearing seat and an air chamber mounting seat, wherein the main pin bearing seat comprises a mounting part for fixing the air chamber bracket and a hollow cylinder part arranged under the mounting part, and four bolt holes are formed in the mounting part; the camshaft bearing seat comprises a hollow long cylinder part arranged above the mounting part, and connecting positions between the mounting part and the camshaft bearing seat are cast into a whole in a manner of transitional connection. According to the lightweight air chamber bracket disclosed by the invention, a hollow inner cavity is removed, cores used for casting are reduced, and the weight of a product is further lightened by 20%, so that the casting cost is reduced; besides through the lightweight air chamber bracket, lengths of connecting bolts are shortened by 2/3, so that the cost of parts is reduced; besides through the lightweight air chamber bracket, a machining cutting tool is saved, so that the machining cost is reduced, finally the weight of the complete vehicle is lightened, and the cost of the complete vehicle is reduced.
