Description

Technical Field

[0001] The utility model belongs to the field of commercial vehicle parts, and in particular relates to a commercial vehicle part. Background Art

[0002] A commercial vehicle fender bracket is a transitional structural component used to secure the fender to the underside of the vehicle's longitudinal beam. This bracket typically utilizes a cantilever beam design, and its primary function is to absorb vibration energy from the fender during vehicle operation through its own elastic deformation.

[0003] Currently, fender brackets generally feature a split structure, consisting of a cast iron or cast steel base and a steel tube. The base is fixed to the underside of the longitudinal beam, while the steel tube is inserted into the base to a certain depth and connected to the base through bolts or welding to form a complete fender bracket. Due to the connection method between the components, this traditional fender bracket structure often experiences loosening or cracking at the joints during vehicle operation. This not only makes the fender bracket prone to breakage, but also has attracted significant attention from companies, as the resulting market claims remain high. Furthermore, due to the material and design, this bracket is relatively heavy, which to some extent affects vehicle performance.

[0004] Composite materials are now widely used. Composite materials refer to materials composed of two or more different substances combined in different ways. They can give full play to the advantages of various materials, overcome the defects of single materials, and expand the application range of materials.

[0005] Therefore, it is particularly important to develop a new, lighter fender bracket structure. Utility Model Content
