Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0026] An example of the present invention Figures 1 to 4 As shown, a leaf spring composite cover plate includes a skeleton 1, the upper end surface of the skeleton 1 fits with the inner curved section of the U-bolt 11, the skeleton 1 is arranged in a matrix 2 made of fiber reinforced polymer material, and the skeleton 1 is made of metal , the lower end surface of the skeleton 1 is flush with the lower end surface of the base body 2 , and the upper end face of the skeleton 1 is exposed on the surface of the base body 2 . There are two skeletons 1 in total, and the two skeletons 1 are independent metal parts and are arranged in the same base body 2 . The base body 2 is provided with a buffer block installation hole, the buffer block 3 is installed in the installation hole, the lower end is flush with the lower end surface of the base body 2 , and the u...

Abstract

The invention discloses a blade spring composite cover plate. The blade spring composite cover plate comprises frameworks, the upper end surfaces of the frameworks are matched with an inner bend section of a U-shaped bolt, the frameworks are arranged in a matrix made of a fiber-reinforced polymer material and are made of a metal material, the lower end surfaces of the frameworks are flush with thelower end surface of the matrix, and the upper end surfaces of the frameworks are exposed out of the surface of the matrix. According to the blade spring composite cover plate, the upper surfaces ofthe frameworks are matched with the inner bend section of the U-shaped bolt and transmit the vertical static / dynamic load from the U-shaped bolt, the load borne by the upper surfaces of the frameworksare jointly borne by the frameworks and the matrix in the cover plate, the frameworks adopt the metal material, so that high structural strength and rigidity can be ensured, the matrix adopts the fiber-reinforced polymer material, the elastic modulus is small, the specific strength is high, and the effects of buffering and dispersing the load are obvious; and moreover, the high polymer material is light in weight, the weight reduction rate of the overall composite cover plate compared with that of a traditional cast iron blade spring cover plate is greater than or equal to 50%, and the lightweight design can be realized.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, and in particular relates to a leaf spring cover plate. Background technique [0002] The leaf spring suspension system is widely used in automobiles. It has the characteristics of mature and reliable structure and is convenient for mass production. The leaf spring cover plate is an important part of the leaf spring suspension system and bears vertical loads and impacts. [0003] The existing leaf spring cover is generally cast iron or sheet metal, which will damage the leaf spring and fastening bolts during use; moreover, the leaf spring cover made of cast iron is heavy and not suitable for the light weight of today's automobiles. development requirements. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a lightweight leaf spring cover. [0005] In order to solve the above technical problems, the present invention is achieved...
