Wintek suspension, trailing arm, rear axle kinematics, anti-squat, commercial vehicle dynamics, suspension compliance. 1. Introduction In the automotive chassis engineering domain, the rear suspension of light commercial vehicles faces a fundamental paradox: the need for high lateral stiffness for load stability versus the requirement for vertical independence to improve ride harshness. Traditional solutions—Hotchkiss drive leaf springs or rigid beam axles with Panhard rods—excel in load capacity but perform poorly in dynamic wheel alignment. Future work should focus on active bushing technology
