Problems solved by technology

[0005] Since the support shaft 20 is to be penetrated, the left and right flat parts 18, 18 on the pivot plate 17 need a large width, and the front and rear lengths of the flat parts 18, 18 become larger, so the volume of the pivot plate 17 is increased. get bigger

Embodiment Construction

[0050] Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings. The figure takes the symbol direction as the viewing direction.

[0051] figure 1 It is a side view of a motorcycle having the frame structure of the present invention, and the motorcycle 10 is a vehicle in which a main frame 12 extending diagonally rearward and downward from a top tube 11 passes through and downward. The pivot plate 13 mounted on the rear end of the main frame 12 in an extended manner supports the power unit 18, which is composed of the engine 16 and the transmission 17, and the fuel tank 23 is installed from the rear of the main frame 12. A trunk 24 is attached to the fuel tank 23 and the rear frames 21 and 22 by attaching a trunk 24 to the pair of left and right rear frames 21 and 22 (only the symbol 21 on the front side is shown) extending diagonally rearward and upward. The tandem seat 26 is attached to the trunk 24 so...

Abstract

Disclosed is a two-wheeled motorcycle, which reduces the volume of a pivot plate and improves rigidity by improving the frame structure. It is provided with a main frame (12) extending obliquely downward from the jack pipe, connected with the rear portion of the main frame (12) and extending obliquely upward rearwardly (21), (22) and the main frame The power unit (18) supported by the lower part of the frame (12), the pivot plate (13) is arranged on the rear lower part of the main frame (12), and the pivot tube (114) is arranged on the pivot plate (13) On the back side (13a), the rear fork (47) is supported in a swingable manner by the pivot tube (114).

Description

technical field [0001] The present invention relates to the improvement of the frame structure of the motorcycle. Background technique [0002] As is well known, in the frame structure of a conventional motorcycle, a pivot plate is attached to the rear of the main frame, and a pivot is attached to the pivot plate (for example, refer to Patent Document 1: Japanese Patent Publication No. 3548173). [0003] in Patent Document 1 figure 2 and Figure 5 It is described below that the pivot plate 17 is attached to the rear portion of the main frame 13 constituting the vehicle frame, the support shaft 20 is attached to the pivot plate 17, and the rear fork 21 that supports the rear wheel is free It is mounted on the support shaft 20 so as to swing up and down. [0004] The pivot plate 17 is composed of left and right flat plate portions 18 and 18 and a connecting plate portion 19 connecting these flat plate portions 18 and 18, and the support shaft 20 is attached to it so as to ...
