Abstract

The invention discloses an aluminum alloy split-type I-type thrust rod, wherein the material of the thrust rod is aluminum alloy, and the preferred composition can be Al-Cu-based alloy, Al- Si-based alloys, Al-Mg-Si-based alloys, Al-Mg-Si- Cu-based alloy or Al-Mg-based alloys, and aluminum alloys in which trace alloying elements such as Sr, La, Ce, Y, Sc, Er, Nb, B, and Cr are added to the aluminum-based alloys. The aluminum alloy split-type I-type thrust rod sleeve is composed of a ball head and a ball hinge, two ends of the sleeve are respectively installed with a ball head, and the ball hinge is installed in a through hole of the ball head; The neck of the spherical head is a combination of an elliptical shape and an arc shape, which improves the bearing capacity. The aluminum alloy thrust rod sleeve and the ball head are prepared by a hot extrusion molding and / or a forging molding process. As that sleeve and the ball head are arrange by friction welding or friction stir welding, the thrust rod is obtained, and the weight reduction effect can reach 40 to 70 percent.

Description

technical field [0001] The invention relates to an I-type thrust rod for automobiles, in particular to an aluminum alloy lightweight thrust rod, a preparation method thereof, and an assembly method of the thrust rod. Background technique [0002] Facing the pressure of environmental protection and energy saving and emission reduction, automobile lightweight has become an inevitable choice for the renewal of automobile design. In the field of trucks, the total mass of a truck is the sum of the vehicle load and the self-weight of the vehicle body. Traffic regulations have clear requirements for the total weight. Overweight will not only bring safety hazards but also violate traffic regulations. Therefore, with the improvement of vehicle requirements in the transportation environment, in order to improve transportation profits, the lightweight of truck parts has become an urgent problem to be solved. [0003] The thrust rod is one of the key components of the balance suspensio...
