A vehicle understructure includes a hydrogen tank that is disposed along a longitudinal axis of a vehicle. At least an upper portion of the hydrogen tank is enclosed in a floor tunnel. The hydrogen tank includes dome portions that are disposed at both ends of a cylindrical center body portion of the tank, and at least one valve portion that protrudes from at least one of the dome portions. The vehicle understructure also includes a brace that extends along a transverse axis of the vehicle and is secured to transversely outer side portions of the floor tunnel. The brace is at least partially overlapped with at least one of the dome portions when viewed from the front or rear of the vehicle.

A composite floor is provided comprising a skeletal framework, foam core inserts, an impact resistant sheet, and a weather resistant sheet bonded together with adhesive. Recreational vehicles incorporating such floors are also contemplated, as are methods of making the composite floor.

An exemplary approach for protecting floorings in containers may utilize a first ledger attached to an upper portion of a first support beam associated with a foundational base assembly. A portion of the first ledger may protrude outward in a first horizontal direction from the upper portion of the first support beam. A second ledger may be attached to an upper portion of a second support beam next to the first support beam. A portion of the second ledger may protrude outward in a second horizontal direction from the upper portion of the second support beam. The second horizontal direction may face the first horizontal direction. A support panel may be placed on top of the portion of the first ledger and the portion of the second ledger. The support panel may have a length proximate to a distance between the first support beam and the second support beam.

An exhaust system device (1) for a vehicle (100) comprises an exhaust purification device (18) and a first exhaust gas recirculation (EGR) cooler (24). The exhaust purification device (18) is disposed with a central axis of a downstream-side end inclined downwardly toward a rear side of the vehicle (100). The EGR cooler (24) is provided so as to introduce exhaust from a downstream side of the exhaust purification device (18), is adjacent to the exhaust purification device (18) and fixed to the exhaust purification device (18), and is disposed such that a central axis of the EGR cooler (24) is inclined downwardly toward the rear side of the vehicle.

Each of a monocoque body and a subframe is integrally formed of reinforced resin. The subframe has a bottom portion and an upstanding portion. The bottom portion is fixed to the lower portion of the rear wall of the monocoque body and extends rearward of the vehicle. The upstanding portion extends upward from the bottom portion. An engine is directly mounted on the rear surface of the upstanding portion.

A cross car beam assembly is provided herein. A composite beam structure extends transversely across a vehicle. A vehicle floor bracket is disposed below the composite beam. A composite reinforcement has a first portion fixedly engaged to the beam structure and a second portion engaged to the vehicle floor bracket.

A vehicle body lower portion structure includes: a lower frame member formed as a chamber that extends in a vehicle body longitudinal direction, having a guide portion at inner surfaces of wall portions that structure the chamber, the lower frame member being disposed at a vehicle body lower side; and a reinforcing member formed as a second chamber that extends in the vehicle body longitudinal direction, having a plurality of projections at outer surfaces of wall portions that structure the second chamber, the reinforcing member being provided within the chamber of the lower frame member in a state in which the plurality of projections are made to contact the guide portion.

A control arm includes a wheel side end, a body side end, a first connecting member extending between the wheel side end and the body side end, a second connecting member extending between the wheel side end and the body side end, and having a reduced section portion, and a fracture zone extending through the first and second connecting members in a substantially fore-aft direction of the vehicle, the reduced section portion being within the fracture zone. A thickness of the reduced section portion is tunable to establish a controlled fracturing during a small overlap rigid barrier impact event where: (i) an initial fracture of the first connecting member occurs within the fracture zone, and (ii) a secondary fracture of the second connecting member occurs within the fracture zone at the reduced section portion, to thereby provide a desired rearward trajectory of the wheel assembly during the impact event.

A structural small overlap rigid barrier (SORB) joining bracket for a vehicle having an underbody hold-down assembly, a cowl side assembly, and a body mount assembly configured to connect a vehicle body to a vehicle frame includes a cowl side coupling first portion configured to couple to the cowl side assembly, and an underbody coupling second portion configured to couple to the underbody hold-down assembly and the body mount assembly. The SORB joining bracket couples and maintains structural integrity between the underbody hold-down assembly and the cowl side assembly, and couples with the body mount assembly to increase vehicle load capacity by providing a direct load path into the frame of the vehicle. A frame extension tube assembly creates additional strength and stiffness via stack-up with the SORB joining bracket.

A structural panel joining part for a vehicle having an underbody hold-down panel, a floor panel, a dash panel, and a cowl side panel includes an underbody coupling first portion configured to couple to at least one of the underbody hold-down panel and the floor panel, a dash panel coupling second portion configured to couple to the dash panel, and a cowl side coupling third portion configured to couple to the cowl side panel. The structural panel joining part maintains structural integrity between the underbody hold-down panel, the floor panel, the dash panel, and the cowl side panel to provide structural reinforcement during small overlap rigid barrier impacts to facilitate reducing structural intrusion into an occupant compartment of the vehicle.
