An exhaust purification device introduction passage 17 connecting the exhaust manifold 12 and the exhaust purification device 18 is disposed on the other side of the center of the exhaust manifold 12 in the cylinder-array direction, and extends below the exhaust manifold 12 to be connected to the exhaust purification device 18.

A vehicle body structure includes a side sill having a closed cross-section portion, and a reinforcement body inside the closed cross-section portion and joined to the side sill. The reinforcement body comprises first and second reinforcement portions. The first reinforcement portion has a first bonding surface on the upper side and is joined to an inner wall of the closed cross-section portion at a portion other than the first bonding surface, and the second reinforcement portion has a second bonding surface facing the first bonding surface from above the first bonding surface, and is joined to the inner wall at a portion other than the second bonding surface. The first and second bonding surfaces are bonded together through a damping member made of an adhesive material. The first and second bonding surfaces are disposed at an inclination angle of 30 degrees or less with respect to a horizontal plane.

A lower vehicle-body structure comprises a vehicle floor comprising a bottom face portion and a floor tunnel which protrudes upwardly and extends in a vehicle longitudinal direction, a pair of right-and-left floor cross members extending in a vehicle width direction on both sides of the floor tunnel, and a connecting member provided to extend in the vehicle width direction at a position which overlaps the floor cross members in the vehicle longitudinal direction and be fixed to at least one of the vehicle floor and the floor cross members at plural fixation positions. These plural fixation positions are located at plural different levels in a range of a height of the floor cross members.

A lower vehicle-body structure comprises a vehicle floor comprising a bottom face portion and a floor tunnel, a pair of right-and-left first floor cross members extending in a vehicle width direction and provided on both sides of the floor tunnel, a pair of right-and-left second floor cross members extending in the vehicle width direction and provided on both sides of the floor tunnel, the second floor cross members being spaced rearwardly from the first floor cross members, a first connecting member provided to extend in the vehicle width direction at a position overlapping the first floor cross members in the vehicle longitudinal direction, and a second connecting member provided to extend in the vehicle width direction at a position overlapping the second floor cross members in the vehicle longitudinal direction.

A vehicle undercover mounting bracket for mounting an undercover body is provided. The vehicle undercover mounting bracket includes a frame-side mounting portion mounted on a side rail of a truck frame, an undercover-side mounting portion mounted on the undercover body and spaced apart from the frame-side mounting portion in a longitudinal direction of the side rail, and a connecting portion which extends in the longitudinal direction of the side rail and connects the frame-side mounting portion and the undercover-side mounting portion.

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 vehicle lower part structure includes: center rail portions disposed at a central part in a front-rear direction of the vehicle; front rail portions disposed forward of the center rail portions in the front-rear direction of the vehicle; rear rail portions disposed rearward of the center rail portions in the front-rear direction of the vehicle; front connecting rail portions connecting the center rail portions and the front rail portions in the front-rear direction of the vehicle; rear connecting rail portions connecting the center rail portions and the rear rail portions in the front-rear direction of the vehicle; first mount portions supporting a vehicle body constituting a cabin; and second mount portions supporting the vehicle body.

A device for arranging a passenger restraint system in a vehicle to secure a passenger seated in the vehicle, including a support arrangement having a vertical support and a cross strut. When arranged on the vehicle, the vertical support is arranged upright on a vehicle floor. The device includes a fastening element, that when arranged on the vehicle, encompasses a rail of a vehicle chassis, at least laterally and beneath, such that, when the support arrangement is arranged on the vehicle, the fastening element bears against the support arrangement. The support arrangement is held on the vehicle chassis by the fastening element and, when the support arrangement is arranged on the vehicle, the fastening element passes progressively through the vehicle floor, starting from the rail of the vehicle chassis.

This disclosure relates to a motor vehicle floor assembly, and further relates to a method of constructing a motor vehicle which reduces the number of fixing points (i.e., fastener attachment points) on a vehicle chassis. An example floor assembly includes a vehicle frame, a floor panel, and at least one underbody vehicle component forming a subassembly with the floor panel installed to an underside of the vehicle frame. The floor panel comprises at least one recess configured to receive a portion of the vehicle frame.

An energy absorbing strut having, a first end coupled with an inner cylinder, and a second end connected with a hollow rod extending within the inner cylinder. A piston is carried by the rod having an outer surface sealing against an inside diameter of the inner cylinder and forming a compression chamber and a rebound chamber bounded by the piston, the rod having an internal passageway communicating between the compression chamber and the rebound chamber. An inertial mass carried by the rod movable axially on the rod between a closed position against and annular rod passageway and an open position opening the rod passageway and allowing the flow of a hydraulic fluid between the compression chamber and the rebound chamber. A spring acts on the inertial mass biasing the inertial mass toward the closed position. The energy absorbing strut may be used in a blast mitigation system for a military vehicle or other applications for providing shock isolation between two structures.
