Abstract
The invention discloses an aluminum alloy split-type I-type thrust rod. The material of the thrust rod is aluminum alloy, and the preferred components are Al-Cu alloy, Al-Si alloy, Al-Mg-Si alloy, Al- Zn-Mg-Cu-based alloys or Al-Mg-based alloys, and aluminum alloys in which trace alloying elements such as Sr, La, Ce, Y, Sc, Er, Nb, B, Cr, etc. are added to the above-mentioned aluminum-based alloys. The thrust rod is composed of a bushing, a ball head and a ball hinge, and the two ball heads are respectively installed at both ends of the bushing; the neck of the ball head is a combination of an ellipse and an arc shape, which improves the bearing capacity; the ball head There are through holes for placing ball joints on the top. The aluminum alloy thrust rod ball head is prepared by a casting molding process. The casing and the ball head are assembled by friction welding or friction stir welding to obtain the thrust rod of the present invention, and the weight reduction effect can reach 40-70%.
Description
technical field [0001] The invention relates to an I-shaped 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 bring safety hazards and 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 suspension and air su...
