The role of the car transmission bracket
The main functions of the vehicle transmission bracket include stabilizing the body, damping and cushioning, ensuring the free lifting of the side window glass, and connecting the side window glass with the body elevator to ensure the interior ventilation . In addition, the transmission bracket is glued to the glass by polyurethane adhesive, and the side window glass is then installed on the side door to ensure its stability and functionality .Specific application scenarios and materials.
The car lower bracket is usually divided into plastic and metal two materials. Plastic brackets are often manufactured by injection molding, while metal brackets are mainly connected by spot welding after stamping. No matter what kind of material, the surface of the bracket must be kept smooth and flat, without cracks, uneven color, dents, impurities, scratches or sharp edges .
Differences in different types of brackets
There are many types of brackets, which can be subdivided into many types according to different materials and structures. For example, the bracket bonding process in Fuyao factory uses a stay-proof and error-proof design and a reflecting sensor to accurately detect the position of the bracket and avoid the situation of missing glue. Fuyao has invested a lot of effort in the technology research and development and process innovation of the bracket, obtained a number of related patents, and won the wide recognition of the market with high-quality products .
The materials of automobile transmission brackets mainly include high-strength steel plate, aluminum alloy, magnesium alloy, carbon fiber reinforced plastics and glass fiber reinforced plastics . Each of these materials has advantages and disadvantages and is suitable for different needs and application scenarios.
High-strength steel plate : high-strength steel plate has high strength and good stiffness, and is often used in key parts of automobiles, such as the body skeleton and the support structure of the front and rear suspension system. It is able to provide sufficient strength and durability, but the weight is larger .
aluminum alloy : Aluminum alloy has low density, light weight and good thermal conductivity, but relatively low strength and stiffness. It is often used in parts that require lightweight, such as engine mounts, to improve fuel economy and driving stability .
magnesium alloy : magnesium alloy has the lowest density and lightest weight, and has excellent electromagnetic shielding performance, but it is difficult to process and high cost. It is suitable for parts that require extremely high weight, such as the engine mounts of some high-end cars .
carbon fiber reinforced plastics : carbon fiber reinforced plastics have the characteristics of high strength, high stiffness, light weight and corrosion resistance, but it is difficult to process and high cost. It is commonly used in high-performance vehicles and high-end models, such as the carbon fiber engine compartment bracket of the Audi R8 .
glass fiber reinforced plastics : glass fiber reinforced plastics have higher strength and stiffness, light weight and low cost, but poor corrosion resistance. It is suitable for some common vehicle components, such as certain brackets and brackets .
Choosing the right material requires a comprehensive consideration of the vehicle's needs, cost budget and performance requirements.
