Abstract

Official abstract text for this publication.

A suspension sub frame structure comprises a suspension sub frame provided to extend in a vehicle longitudinal direction and supporting a suspension link, an extension frame provided to extend forwardly from a front end of the suspension sub frame and having lower rigidity against a load applied in the vehicle longitudinal direction than the suspension sub frame, and a cross member provided to extend in a vehicle width direction on an inward side, in the vehicle width direction, of the both frames, wherein the cross member is joined to the both frames at a joint area which is continuous in the vehicle longitudinal direction.

First claim

Opening claim text (preview).

What is claimed is: 1. A suspension sub frame structure, comprising: a suspension sub frame provided to extend in a vehicle longitudinal direction and supporting a suspension member of a front wheel; an extension frame provided to extend forwardly from a front end of the suspension sub frame and having lower rigidity against a load applied in the vehicle longitudinal direction than the suspension sub frame; and a cross member provided to extend in a vehicle width direction on an inward side, in the vehicle width direction, of the suspension sub frame and the extension frame, wherein said cross member is joined to said suspension sub frame and said extension frame at a joint area which is continuous in the vehicle longitudinal direction; and wherein said joint area comprises a front-side joint area where said cross member is joined to said extension frame and a rear-side joint area where said cross member is joined to said suspension sub frame, and said front-side joint area is shorter than said rear-side joint area. 2. The suspension sub frame structure of claim 1 , wherein said cross member comprises an upper-face joint portion which is joined to an upper face of said extension frame and an upper face of said suspension sub frame at said joint area and a lower-face joint portion which is joined to a lower face of said extension frame and a lower face of said suspension sub frame at said joint area. 3. The suspension sub frame structure of claim 2 , wherein a bracket to make said suspension sub frame support said suspension member is attached to said extension frame and said suspension sub frame at an area which is continuous in the vehicle longitudinal direction. 4. The suspension sub frame structure of claim 1 , wherein a bracket to make said suspension sub frame support said suspension member is attached to said extension frame and said suspension sub frame at an area which is continuous in the vehicle longitudinal direction.
