Abstract: A motor vehicle front subframe includes a pair of main longitudinal beams each formed from an extrusion with a flange casting at the rear end and a suspension tower at the other end. Two lower longitudinal beams extend parallel to the main longitudinal beams and are connected by a cross member. Each lower longitudinal beam has a horizontal front flange where it is attached to a corresponding flange face at the lower end of the adjacent suspension tower. Two intermediate longitudinal beams are attached to the suspension towers and to a main cross-member and forward are two crush cans to which is attached a bumper armature. The vehicle has a body with a passenger compartment and vertical pillars just forward of the passenger compartment. Suitable bolts or set screws are then inserted to secure the front subframe to the body and the rear subframe is attached to the body.

Abstract: A joint assembly comprises a hollow extrusion member of an asymmetrical hexagonal section and a flange casting comprising a base flange and several webs including a top web and upper side webs which have joint faces presented to corresponding joint areas on the outside of the extrusion while a bottom web and lower side webs have joint faces which are presented to corresponding joint areas on the inside of the extrusion. To assemble the joint assembly an adhesive is applied to the joint faces and the extrusion aligned with the flange casting but offset vertically. The extrusion is then moved longitudinally towards the flange casting to the full extent permitted by abutment of an extrusion end face with steps to bring the joint faces into overlapping alignment with the corresponding joint areas on the extrusion, there being a substantial clearance due to the vertical offset so that the adhesive on the joint faces does not contact the joint areas on the extrusion at this stage.
