Abstract: A vehicle body frame is such that hollow frame members 40 such as side frames extending longitudinally along a vehicle body are provided thereon. Two inner partition plates 42, 43 are integrally formed in the interior of each of the hollow frame member in such a manner that the two inner partition plates extend in a longitudinal direction of the frame member and are close to each other along plate surfaces 42a, 43a thereof, so that a central space portion 44 defined by the two inner partition plates therebetween is formed in the interior of the hollow frame member, whereby side plates 41 constituting the hollow frame member can be dissociated at portions of the side plates which face the central space portion by virtue of a buckling load.

Abstract: A vehicle body frame is such as to be provided with cast hollow frame members 40 such as side frames extending longitudinally along a vehicle body. A plurality of ribs 53 . . . are provided at certain regular intervals p11 on an inner circumferential surface 41 of the cast hollow frame member so as to partition the interior of the hollow frame member longitudinally at the certain regular intervals p11. The hollow frame member buckles and deforms subsequently from one end 42 thereof at the certain regular intervals so that the crash energy can be absorbed stably and sufficiently.

Abstract: A steering column hanger beam 21 extended between left and right front pillars 13, 15 for supporting a steering column 65 is constructed as an in-line connected body comprising a driver's side hanger beam 22 having a large diameter cross-section and a front passenger's side hanger beam 60 having a small diameter cross-section.

Abstract: There is provided a construction for suspension system mounting portions of the body of a vehicle characterized in that a closed cross-sectional portion (19) extending in a transverse direction of the body of the vehicle is formed with a plurality of sheet materials (a front dash panel 1 and a dash panel lower cross member 7) which are each pressed into shapes, that an extruded beam member (a reinforcement beam 17) is caused to extend into the interior of the closed cross-sectional portion, die-cast suspension arm brackets (6) are welded to an external surface of the closed cross-sectional portion with a part thereof (protruding portions 15a, 15b) being caused to protrude into the interior of the closed cross-sectional portion, and that the beam member is welded to the protruding portions. This can provide high rigidity without involving the complexity in shaping the respective members constituting the closed cross-sectional portion.

Abstract: A framework structure of an automobile body formed of a lightweight metal material is provided, wherein a press-molded member is placed at a joint part of a die casting member and an extrusion-molded member. In doing so, insufficient toughness of the die casing member is reinforced by the press-molded member, so that the impact energy absorption performance of a welded joint part of the die casting member and the extrusion-molded member is enhanced.

Abstract: A hollow frame member of an aluminum alloy for a vehicle body frame includes a front pipe portion. The front pipe portion has an annular end surface as a surface receiving a collision load at a front end thereof. In the front pipe portion, a cross sectional area is gradually increased from a base end toward the receiving surface, and a thickness is gradually decreased from the base end toward the receiving surface. Thus, the front pipe portion can be crushed early and stably from the receiving surface upon collision of the vehicle to enhance the collision energy absorbing efficiency.

Abstract: A lightweight metal automobile framework having a hollow, impact-absorbing member, wherein the impact-absorbing member absorbs any impact by axial plastic deformation and has inner ribs passing through a center axis thereof. The impact-absorbing member may also have an axial end face partially removed to lessen an area on which a load is imposed at an instant of impact, thereby raising the average stress of the impact and lowering peak deceleration. Also, automobile framework members forming a front-end portion of the automobile framework may be detachably coupled to the automobile framework.

Abstract: To mount a fuel tank storing a compressed fuel gas on an automobile, the tank is placed on a tank supporting frame and tightened to the frame by a belt, pipes neighboring with the tank and leak preventing seals are assembled with the tank, the tank supporting frame installed with the fuel tank is mounted and fixed on a car body, and then the pipes neighboring with the tank are connected to pipes of the car body side.

Abstract: A bomb supporting frame for supporting fuel bombs which store pressurized gaseous fuel in an automobile. The bomb supporting frame is fixed on a floor provided on right and left rear side frames of a vehicular body, and simultaneously it is fixed on damper strut mounting portions of right and left rear wheel houses.
