Transmits torque from differential to wheels, and adapts angle variation caused by suspension travel. Automotive half‑shaft, also named constant‑velocity drive shaft, belongs to critical drivetrain safety components. It transmits torque from differential assembly to driving wheels. During cornering and suspension travel, working angles and axial lengths change continuously. Constant‑velocity joints maintain uniform angular‑velocity output, avoiding
Guiding component for window glass movement, constrains glass travel path and cooperates with regulator for smooth window lifting. Window regulator guide rail is the core guiding mechanical component inside vehicle door assemblies. It constrains window‑glass travel trajectory and bears lateral squeezing load from vehicle glass. Along with plastic sliding blocks, it constitutes the motion‑pair system
HVAC damper actuator components. Drive air duct damper switching to adjust air outlet mode and cold warm air distribution. HVAC air‑duct pull rods and actuator rocker arms are critical mechanical transmission components inside vehicle heating‑ventilation‑and‑air‑conditioning assemblies. These plastic‑dominated linkage parts convert rotary motion from electric HVAC actuators into damper angular displacement, realizing cold‑hot‑air mixing and
