Embodiment

[0047]A scooter-type vehicle according to the present invention will be described based on the drawings.

[0048] Such as figure 1 As shown, the scooter-type vehicle 10 has: a front fork 13 that is steerably supported on a head pipe 12 of a body frame 11 (details will be described later); The front axle 14 at the lower end of the front fork 13; the handlebar 16, which is connected to the upper end of the front fork 13, for the driver to hold and manipulate the front wheel 15; 20 (details described later) are combined at the lower end to extend rearwardly (L is a sign indicating left. The same below. See the details later); the rear frame 70L, its front end is combined with the horizontal tube 60 at the rear end of the bottom frame 30L (details will be described later) are combined to extend rearward and upward (details will be described later); the power unit 104 is swingably fixed to the engine suspension link 101 connected to the lower front end of the rear frame 70L by mea...

Abstract

Disclosed is a frame structure that is of a scooter-type vehicle (10) and that is provided with: a header pipe (12) that steerably supports a front fork (13); a hollow main pipe (20) extending downwards and to the rear of the vehicle body from the header pipe; a left-right pair of lower frames (30L, 30R) that are joined to the bottom of the main pipe and that each extend to the rear of the vehicle body from the bottom of the main pipe; a cross pipe (60) that is connected to each of the back ends (31L, 31R) of the lower frames and extends in the widthwise direction of the vehicle; and a left-right pair of rear frames (70L, 70R) that extend upwards and to the rear of the vehicle body and of which the front ends (71L, 71R) are respectively joined to the left and right ends (63L, 63R) of the cross pipe. The lower frames and the rear frames are joined to the cross pipe, and additionally the at least a portion of the lower frames and at least a portion of the rear frames are joined.

Description

technical field [0001] The present invention relates to an improvement in the frame structure of a scooter type vehicle. Background technique [0002] In scooter-type vehicles, in order to ensure rigidity, it is known to bridge the left frame and the right frame with cross pipes (for example, refer to Patent Document 1). [0003] The body frame of the scooter-type vehicle disclosed in Patent Document 1 includes a cross tube connected to the rear end of the bottom frame and supporting the front end of the rear frame tube. [0004] The transverse tube extends linearly in the vehicle width direction, supports the left underbody frame and the rear frame tube, and supports the right underbody frame and the rear frame tube. [0005] In recent years, in order to improve fuel consumption, it is desired to reduce the thickness of the frame and reduce the weight of the frame. However, in the case of merely reducing the thickness of the frame, lowering of the strength of the frame, l...
