Embodiment Construction

[0024] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. It is further to be noted that terms such as "up", "down", "right", "left", etc. referring to directions or the like refer to the illustrations in the drawings or figure 1 The actual arrangement shown is used here.

[0025] refer to figure 1 and 2 , the motorcycle 1 has a body frame 2 of the lower bone type, and in the body frame 2, a main frame 4 extends downward from a head pipe 3 located at the front head in a rearward tilting direction, and a pair of left and right rear frames (seat rails 5 ) extends obliquely upward in the rearward direction from a portion near the rear end of the main frame 4 , and a rear frame (seat post 6 ) supporting the seat rail 5 is arranged on the rear side of the seat rail 5 . In addition, to the main frame 4, a front engine support frame 7 is attached to an adjacent portion of the connecting portion connected to the seat ra...

Abstract

The present invention provides a body frame structure of a motorcycle. In the body frame structure of the motorcycle, on a pair of pivot boards, a pivot pipe passes through the pair of pivot boards for fixing. Furthermore an engine supporting part which supports the back part of the engine is provided above the pivot pipe. When viewed from the vehicle side, a reinforcing board is equipped in the pair of pivot boards. The reinforcing board is provided with a vertical extending part and a frontward extending part. The vertical extending part extends from the lower surface of a main frame vertically basically to the pivot pipe which is equipped behind the engine supporting part. The frontward extending part extends to the front end of each pivot board from the upper end of the vertical extending part along the main frame. The vertical extending part of the reinforcing board is connected with at least one in the lower surface of the main frame, the upper outer circumferential surface of the pivot pipe and inner surfaces of the pair of pivot boards. The frontward extending part is connected with at least one in the side surface of the main frame and the inner surfaces of the pair of pivot boards.

Description

technical field [0001] The invention relates to a body frame structure of a motorcycle. Background technique [0002] Typically, the torsional stiffness of the body frame, which contributes significantly to the steering stability of the motorcycle, is determined by the structural stiffness from the head tube to the pivot tube. [0003] In this body frame structure, if the main frame having the front end portion connected to the head pipe is directly connected or coupled to the pivot tube, the torsional rigidity of the body frame is improved. However, in a motorcycle having an under-bone type body frame, it is difficult to directly connect or couple the main frame to the pivot tube due to limitations in the shape of the crankcase of the engine and the like. [0004] Therefore, for example, in the body frame structure of a motorcycle disclosed in Patent Document 1 (Japanese Patent Laid-Open Publication No. 2008-296832), the rear end portion of the main frame is connected to t...
