Abstract
Official abstract text for this publication.
A sub frame structure of a vehicle comprises a pair of right-and-left side members, to which a pair of right-and-left uppers-side lower arms are connected, a rear cross member holding rear ends of the side members, and a front cross member interconnecting the side members and being positioned in front of the rear cross member, being spaced apart from the rear cross member. A front end of each of the side members is rigidly connected to a floor frame, the front cross member is joined to a front side member of each of the side members, and a rear side member is provided at a portion of each of the side members which is positioned in back of the front cross member. Herein, the rear side member is configured to be weaker than the front side member.
First claim
Opening claim text (preview).
What is claimed is: 1 . A sub frame structure of a vehicle, comprising: a pair of right-and-left side members extending in a vehicle longitudinal direction, to which a pair of right-and-left arm members supporting right-and-left rear wheels are pivotally connected; a rear cross member holding the vicinity of respective rear ends of the pair of right-and-left side members; and a front cross member interconnecting the pair of right-and-left side members in a vehicle width direction and being positioned in front of the rear cross member, being spaced apart from the rear cross member, wherein a front end of each of said side members is rigidly connected to a vehicle body, said front cross member is joined to each of the side members at a position located in back of the vicinity of the front end of the side member, and a weak portion is provided at a portion of each of the side members which is positioned in back of the front cross member, the weak portion being configured to be weaker than another portion of each of the side members which is positioned in front of the front cross member. 2 . The sub frame structure of the vehicle of claim 1 , wherein a portion of each of said side members which is positioned between said front cross member and said rear cross member is configured to slant inward, in the vehicle width direction, relative to a vehicle longitudinal direction in a plan view. 3 . The sub frame structure of the vehicle of claim 1 , wherein said side members are provided to protrude rearward beyond said rear cross member. 4 . The sub frame structure of the vehicle of claim 2 , wherein said side members are provided to protrude rearward beyond said rear cross member. 5 . The sub frame structure of the vehicle of claim 1 , wherein each of said side members is formed in a roughly tubular shape having an inside hollow space, and a thickness of said weak portion of the side member is configured to be thinner than that of said portion of the side member positioned in front of the front cross member. 6 . The sub frame structure of the vehicle of claim 2 , wherein each of said side members is formed in a roughly tubular shape having an inside hollow space, and a thickness of said weak portion of the side member is configured to be thinner than that of said portion of the side member positioned in front of the front cross member. 7 . The sub frame structure of the vehicle of claim 3 , wherein each of said side members is formed in a roughly tubular shape having an inside hollow space, and a thickness of said weak portion of the side member is configured to be thinner than that of said portion of the side member positioned in front of the front cross member.
