D’fhonn luasghéarú chreathadh an fhráma agus an choirp a luathú agus compord turas (compord) an ghluaisteáin a fheabhsú,ionsúirí turraingsuiteáilte i gcóras fionraí fhormhór na ngluaisteán.
Tá córas ionsú turrainge carr comhdhéanta de thobar agus aionsúire turraing. The ionsúire turraing is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact. The spring plays the role of alleviating the impact, changing the "high energy one impact" into "small energy multiple impact", and the ionsúire turraing gradually reduces the "small energy multiple impact". If you have driven a car with a broken ionsúire turraing, you can experience the bouncing of the aftermath of the car going through every pothole and ups and downs, and the ionsúire turraing is used to suppress this kind of bounce. Without a ionsúire turraing, the rebound of the spring cannot be controlled. When the car encounters a rugged road, it will have a serious bounce. When cornering, the tire's grip and tracking will be lost due to the vibration of the spring.
