Thereafter, the method includes fixing a left inboard surface of each left pillar to the floorpan left side and fixing a right inboard surface of each right pillar to the floorpan right side for securing the safety cage to the floorpan.

A method for manufacturing a dissimilar metal joint product includes: spraying a metal powder capable of being joined to a steel material to at least a part of a surface of an aluminum or aluminum-alloy material at a low temperature and at a high speed to form a coating thereon; disposing the aluminum or aluminum-alloy material and the steel material such that the coating and the steel material face each other; and performing brazing using a brazing material or welding using a welding material between the coating and the steel material.

A tailgate system, comprising: (i) a tailgate door configured to pivotally engage a rear cargo area of a body of a vehicle in between a closed position and an open position; and (ii) a bed extension pivotally engaged to the tailgate door and configured to pivot from a closed position to one or more open positions, wherein the bed extension includes a plurality of removable panels.

A vehicle body assembly is described herein, including a first structural component and a second structural component. The first structural component may be a roof component or a side panel, and include a first part including a first metal and a second part including a second metal different than the first metal. The second part is formed on a peripheral edge portion of the first part and defines a mounting flange for the first structural component. The second part is joined to the first part via an ultrasonic additive manufacturing (UAM) interface. The second structural component is including the second metal and is joined to the second part at the mounting flange via a resistance spot weld (RSW) joint.

The disclosure relates to an aluminum alloy and a component part prepared therefrom. The aluminum alloy comprises: 7-9 wt % of silicon (Si), 0.2-0.7 wt % of manganese (Mn), 0.09-0.4 wt % of iron (Fe), 0.1-0.3 wt % of vanadium (V), 0.1-0.2 wt % of titanium (Ti), 0.01-0.03 wt % of strontium (Sr), and the balance being aluminum and inevitable impurities, wherein the weight ratio of the manganese (Mn) to the iron (Fe) is not less than 1. The aluminum alloy of the disclosure can be exempt from heat treatment process after casting in the processing process, so as to contribute to energy conservation and emission reduction, and the component part prepared therefrom can achieve desired mechanical properties.

A door beam of a motor vehicle includes a 7000 series aluminum alloy extruded material, the 7000 series aluminum alloy extruded material including Zn: 7.5 mass % to 9.0 mass %, Mg: 1.3 mass % to 2.0 mass %, Cu: 0.1 mass % to 0.7 mass %, Si: 0.15 mass % or less, Fe: 0.3 mass % or less, Ti: 0.005 mass % to 0.2 mass %, and at least one of Mn, Cr, and Zr: 0.1 mass % to 0.5 mass %, in which contents of Mn, Cr and Zr satisfy Mn: 0.3 mass % or less, Cr: 0.25 mass % or less, and Zr: 0.25 mass %, respectively, with the remainder being Al and impurities. A Fe-based crystallized product is contained, and an average Cu content of the Fe-based crystallized product is 5.0 mass % or less.

An improved trailer chassis assembly primarily constructed from extruded components including an extruded chassis rail component, a cross member component and a connector component. The component has a wall surface defining an interior channel and an opening in the wall surface extending through the wall surface to the interior channel. The connector component has a first region adapted to engage with the interior space of the chassis rail component, and a second region adapted to engage with the cross member component. The interior space of the chassis rail component is adapted to capture movement of the first region of the connector component in vertical and horizontal planes, and yields movement in the axial plane.

A vehicle body structure including: a pair of left and right first vehicle body framework members manufactured by die-casting, and being provided at vehicle width direction outer sides of a vehicle and extending along a vehicle front-rear direction; a pair of left and right second vehicle body framework members manufactured from sheet steel and being joined to a length direction end portion of a corresponding first vehicle body framework member and extending along the vehicle front-rear direction; and a load transmission portion provided at either the first vehicle body framework members or the second vehicle body framework members, the load transmission portion configured to abut the other the first vehicle body framework members or the second vehicle body framework members when a collision load acting substantially along the vehicle front-rear direction is input to the first vehicle body framework members or the second vehicle body framework members.
