Title:
VEHICLE-BODY FRAME FOR AUTOMATIC TWO-WHEEL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/042884
Kind Code:
A1
Abstract:
A vehicle-body frame for an automatic two-wheel vehicle, the vehicle-body frame being provided with a head pipe, with a down frame that extends downward and to the rear from the head pipe, and with a left-right pair of lower frames that are formed to be hollow by joining pressed sheet metal, that are connected to the right and left sides of a lower section of the down frame, and that extend to the rear. The lower frames (19) are directly welded to at least left and right side surfaces of the lower section of the down frame (18) that are formed to be vertically long. An upper end (54a) of a joining section (54) of the lower frames and the down frame is arranged above a first horizontal line (L1) that passes through an upper end of the hollow part of the lower frames at a portion (19c) of the lower frames at which the cross-sectional area thereof is smallest. A lower end (54b) of the joining section (54) is arranged below a second horizontal line (L2) that passes through a lower end of the hollow part of the lower frames at the portion (19c) of the lower frames at which the cross-sectional area thereof is smallest. As a result, the lower frames can be securely joined to the down frame without increasing weight and without increasing man-hours for processing.
