„Toyota“ valdymo rankos varžtas

The control arm connects the wheel to the vehicle body elastically through ball joints or bushings, forming a flexible guide and load-transmitting bridge. This design not only allows the wheel to move freely relative to the vehicle body but also enables precise control over the wheel's position during driving. When the wheel is subjected to external forces (such as bumps, braking, or steering), the control arm transmits these jėgos prie transporto priemonės korpuso, reguliuodami rato trajektoriją per pakabos sistemą, kad būtų užtikrintas stabilumas sudėtingomis kelio sąlygomis .
