Patent

CA 2646618

A frame for a heavy-duty vehicle includes a pair of spaced-apart and longitudinally-extending main members. At least two cross members extend between and are attached to the main members. Each one of at least a pair of hangers is attached to and depends from a respective one of the main members for suspending an axle/suspension system from the frame. A force distribution assembly is attached to the main members and the hangers and includes a component that deforms or shears in an extreme event. The force distribution assembly extends perpendicularly between the main members and interrupts the transmission of forces encountered by the axle/suspension system that move through each one of the hangers to its respective main member, and redirects at least a portion of such forces across said force distribution assembly and into the other one of the main members.

La présente invention concerne un châssis pour un véhicule lourd qui comprend deux éléments principaux qui sont espacés l'un de l'autre et s'étendent longitudinalement. Au moins deux traverses s'étendent entre et sont fixées aux éléments principaux. Chacun d'au moins deux dispositifs de suspension est fixé à et dépend d'un élément principal respectif pour suspendre un système d'essieu/suspension à partir du châssis. Un assemblage de distribution de force est fixé aux éléments principaux et dispositifs de suspensions et comprend un composant qui se déforme ou se cisaille dans un cas extrême. L'assemblage de distribution de force s'étend perpendiculairement entre les éléments principaux et interrompt la transmission des forces rencontrées par le système d'essieu/suspension qui se déplacent à travers chacun des dispositifs de suspension jusqu'à son élément principal respectif, et redirige au moins une partie de telles forces sur ledit assemblage de distribution de force et dans l'autre des éléments principaux.
