Description

Technical field[0001]The invention relates to the technical field of automobile leaf spring structures, in particular to a composite material leaf spring with a pre-embedded central hole sleeve and an assembly process.Background technique[0002]With the development of my country's industrialization and the increase in transportation volume, users have higher requirements for the lightweight of vehicles. In addition, in order to reduce the quality of the car's servicing, improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. As a result, composite leaf springs came into being.[0003]The middle part of the composite leaf spring is used as the area with greater stress, and the connection method of the composite material and the connector directly determines the fatigue life of the composite leaf spring. At present, the traditional method is to use structural adhesive bonding to connect the composite material and the connector, such as the solution disclosed ...
