Description

Lightweight hollow car lateral stabilizer

Technical field

The utility model relates to the technical field of automobile stabilizer bars, in particular to a lightweight stabilizer car transverse stabilizer bar.

Background technique

The anti-roll bar, that is, the stabilizer bar, is an auxiliary elastic element in the suspension of the car. Its role is to prevent excessive lateral roll of the body during cornering. The aim is to prevent the car from tipping over and improving ride comfort. The lightweight hollow car lateral stabilizer bar is a torsion bar spring made of spring steel and has a U-shaped shape that is transverse to the front and rear ends of the car. The middle part of the shaft is hinged to the frame by a sleeve, and the two ends of the rod are respectively fixed on the left and right suspensions. When the body is only used for vertical movement, the suspension deformation on both sides is the same, and the stabilizer bar does not work. When the body is tilted, the suspension flicks on both sides are inconsistent, the stabilizer bar is twisted, and the elastic force of the shaft becomes the resistance to continue the roll, which plays a role of lateral stability. The general anti-roll bar body is designed as a solid structure. Although it can meet the load requirements, it increases the material cost and increases the weight of the car body, so it can not conform to the trend of domestic heavy-duty truck lightweight design, and in actual use.
