Problems solved by technology

[0004] In saddled vehicles such as motorcycles, as described above, the frame deformation can be suppressed by connecting the frames through the cross frame, but the shape of the frame, the position of the frame with the cross frame in the whole vehicle, and the influence of Due to the influence of its rigid engine installation position, the driver's maneuverability and straightness will change

Abstract

A saddle-ride type vehicle has a head pipe (12), and the pair of left and right frame sections (27, 27) extended rearward from the head pipe (12), a cross plate (60) continuously connects the pair of left and right frame sections (27, 27) in a width direction of the vehicle. The cross plate (60) is elastically connected to the left and right frame sections (27, 27). Such arrangement of the cross plate suppresses distortion of a pair of left and right frame sections including the down tubes extended so as to be connected by the head pipe, and also improves the controllability and straight traveling characteristic of the motorcycle.

Description

technical field [0001] The present invention relates to saddle-type vehicles, and more particularly, to an improvement technique for a frame of a saddle-type vehicle. Background technique [0002] In motorcycles, a so-called twin-spar frame structure is adopted, in which a pair of left and right under frames extending rearward and downward are coupled to a head pipe. In such a vehicle body frame, a pipe is generally used as the lower frame. Due to the relatively large size of the double-beam motorcycle, there is a certain distance between the engine and the head pipe. Therefore, the thickness of the pipe is limited due to the appearance restriction, which may cause a large deformation of the lower frame. Therefore, in a relatively large two-wheeled motor vehicle, as described in Patent Document 1, the horizontal frame (cross tube) is connected by welding or the like between the lower frame (lower tube) and the horizontal frame is used as a single rigid body. Technology. ...
