AI Technical Summary
⚠Technical Problem
The existing upper control arms of the suspension mainly use aluminum alloy castings or straight steel rods, which are costly and have low structural strength, affecting the overall vehicle handling stability and NVH performance.
⚗Method used
The rear suspension upper control arm adopts a hollow box-shaped structure formed by folding and welding the first and second steel plates. It is connected to the steering knuckle and the rear subframe through a sleeve to provide installation support and transmit force, thereby enhancing strength and rigidity.
🎯Benefits of technology
It improves the vehicle's handling stability, NVH performance, and durability, while reducing costs and achieving improvements in strength and rigidity.

Abstract
The utility model discloses a rear suspension upper swing arm, rear suspension upper swing arm assembly and vehicle, include: swing arm body, by first end to second end along the length direction, swing arm body includes first steel sheet and second steel sheet, first steel sheet and second steel sheet along the length direction of swing arm body extends, and the edge of at least one of first steel sheet and second steel sheet is equipped with the flanging, and the flanging extends along the length direction of swing arm body, and first steel sheet and second steel sheet are welded to form the hollow box -like structure through the flanging, sleeve pipe, including first sleeve pipe and second sleeve pipe, first sleeve pipe is connected in the first end of swing arm body, and forms first mounting point through first sleeve pipe, and second sleeve pipe is connected in the second end of swing arm body, and forms second mounting point through second sleeve pipe. Compared with casting or straight steel pole, the strength is better, the performance is better, the maximum promotion strength, rigidity and buckling performance, effectively promote the whole car handling stability performance, NVH performance and endurance performance, and reach the cost optimum simultaneously.
