What Causes the Noise from the Vehicle's Subframe?
1 Answers
In reality, the noise is actually caused by friction between metal components. When this noise occurs, it may be due to the following issues: Generally, replacing the stabilizer bar bushings is quite labor-intensive because these bushings are usually located on the subframe, making the disassembly process costly. If the bushings are severely worn, they may produce a thumping or dull sound. If the wear is less severe and the bushings have only hardened, they may emit a squeaking noise. Articulated Subframe: An articulated subframe includes a subframe body, which consists of a C-shaped support frame, connecting brackets, and connecting hinge pins. At both ends of the C-shaped support frame, a connecting bracket is hinged via a connecting hinge pin. Movable Structure: This utility model of an articulated subframe replaces the traditional monolithic subframe with a structure where the C-shaped support frame and connecting brackets are linked via hinge pins. During use, both the connecting brackets and the C-shaped support frame are movable structures. The movement of the hinge pins reduces stress on the articulated joints, thereby minimizing wear. Even if the connecting parts wear out over time, the cost of replacing components can be reduced by simply replacing the hinge pins. This lowers overall usage costs and improves material utilization efficiency.
