The invention discloses an automobile steel plate spring assembly with an auxiliary spring made of a composite material. The automobile steel plate spring assembly comprises a U-shaped bolt metal clamping plate, a main spring, the auxiliary spring and a lower gasket. The lower gasket, the auxiliary spring, the main spring and the U-shaped bolt metal clamping plate are sequentially stacked from bottom to top and then are fixedly connected for limiting through a center bolt, and clamping and fixing are assisted through a U-shaped bolt. The main spring is a steel plate spring, and the auxiliary spring is a composite material plate spring. The auxiliary spring is made of the E glass fibers/polyurethane composite material and is integrally formed through a high-pressure RTM technique. The fiber laying layers of the composite material are all 0 degree, and the volume content of the fibers of the composite material is 58%. According to the automobile steel plate spring assembly with the auxiliary spring made of the composite material, on the basis that the requirement for the performance of an automobile steel plate spring is met, design cost is reduced, the mass of the plate spring assembly is lowered, and the service life of the plate spring assembly is prolonged. The invention further discloses an assembly method of the automobile steel plate spring assembly with the auxiliary spring made of the composite material.
