Vehicles Including Targeted Energy Absorption Structures

摘要

Vehicle structures for dissipating energy associated with a collision are disclosed herein. In one embodiment, a vehicle includes a side support that extends between a front suspension mount and a rear suspension mount of the vehicle. The side support includes a targeted energy absorption portion that defines a high-strength region of the side support. The vehicle also includes a cab mounting bracket coupled to the side support and extending outward from the side support. The cab mounting bracket includes a rearward attachment position on the side support and the rearward attachment position of the cab mounting bracket is positioned proximate to the high-strength region of the side support. The vehicle further includes a wheel assembly that is coupled to the front suspension mount and is positioned forward of the cab mounting bracket in a vehicle longitudinal direction.

主权项

1. A vehicle comprising:
a side support extending in a vehicle longitudinal direction between a front suspension mount and a rear suspension mount of the vehicle, the side support comprising:
a reduced cross-section portion positioned on an outward vehicle lateral direction-facing surface;a targeted energy absorption portion comprising an interior reinforcement member positioned at least partially inside the side support proximate to the reduced cross-section portion, the targeted energy absorption portion positioned between the front suspension mount and the rear suspension mount of the vehicle, wherein the targeted energy absorption portion defines a high-strength region of the side support; a cab mounting bracket coupled to the side support and extending outward in a vehicle lateral direction from the side support, wherein the cab mounting bracket comprises a rearward attachment position on the side support, and the rearward attachment position of the cab mounting bracket is positioned proximate to the high-strength region of the side support; and a wheel assembly coupled to the front suspension mount and positioned forward of the cab mounting bracket in the vehicle longitudinal direction.
