Problems solved by technology

When the car is turning at high speed, due to the influence of centrifugal force, the vehicle will roll over or even roll over, the vehicle will easily lose control, and even accidents involving car crashes and fatalities may occur
In order to prevent the car from rolling, modern cars are generally equipped with anti-roll bars, but if the strength of the anti-roll bar is insufficient, its function cannot be fully exerted, and the phenomenon of car rolling still exists

Abstract

The invention relates to an anti-swing bar, in particular to an aluminum alloy high-strength anti-swing bar, and belongs to the technical field of alloy materials. The high-strength anti-swing bar ismade of an aluminum alloy material, and the aluminum alloy material consists of the following components in percentage by mass: 11.2-11.8% of Si, 1.0-1.5% of Mg, 0.1-0.2% of Cr, 0.25-0.3% of Cu, 0.15-0.25% of Mn, 0.1-0.3% of Zr, and the balance of Al and inevitable impurity elements. The high-strength anti-swing bar is manufactured from the aluminum alloy material, and is added with a covering agent and a K / Na modifier in a preparation process, so that the alloy has high strength and good stress corrosion resistance.

Description

technical field [0001] The invention relates to an anti-roll bar, in particular to an aluminum alloy high-strength anti-roll bar, which belongs to the technical field of alloy materials. Background technique [0002] A member is a member whose longitudinal (lengthwise) dimension is much larger than its transverse (perpendicular to the lengthwise) dimension. The shape and size of a rod can be described by two main geometric elements, the cross section and the axis of the rod. The cross section refers to the section perpendicular to the length direction of the rod, and the axis is the line connecting the centers of each cross section. The cross section and the rod axis are perpendicular to each other. A bar with a straight line axis and the same cross section is called a straight bar of equal section. When the car is turning at high speed, due to the influence of centrifugal force, the vehicle will roll over or even roll over, the vehicle will easily lose control, and even ...
