GLL control arm utilizes a composite structure of high-strength aluminum alloy and specialty steel.GLL through topological optimization, aircraft-grade 7075-T6 aluminum alloy is used in critical stress-bearing areas, ensuring fatigue resistance is improved by over 30% while reducing overall weight by 45% compared to traditional cast iron. GLL used material combination not only meets the strength requirements under extreme operating conditions, but also reduces unsprung mass through lightweight design, significantly improving vehicle handling responsiveness and fuel economy.
GLL utilizes a five-axis CNC machining center and vacuum high-pressure casting technology to ensure that the flatness of the key swing arm mounting surfaces is controlled to within 0.02mm, and the clearance between the ball stud pin hole and bushing is accurate to the micron level. This advanced process not only eliminates the abnormal noise caused by deformation in traditional stamping parts, but also improves the suspension system's response to road impact by 25% by optimizing the mechanical transmission path, significantly reducing wheel track deviation during bumps.
Using a multi-body dynamics (MBD) simulation platform, GLL engineers conducted over 100,000 kilometers of virtual road testing on the swing arm, simulating a full range of operating conditions, from urban roads to off-road trails. By adjusting the swing arm length, bushing stiffness, and ball stud friction coefficient, the product achieved:
Precise wheel alignment: During sharp turns, camber angle variation is reduced by 40%, keeping max tire-ground contact area;
Optimized vibration filtering: GLL bushing utilizes a three-layer composite rubber structure, increasing the attenuation of high-frequency vibrations (10-50Hz) by 35%, significantly reducing interior noise;
Breakthrough durability: Verified on a biaxial fatigue tester, after 200,000 km of simulated harsh road conditions, the swing arm showed no cracks in key areas, and ball stud wear was only one-third of the industry average.
