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

[0051] figure 1 It is a side view of a two-wheeled motorcycle equipped with the frame structure of the present invention. The two-wheeled motorcycle 10 is a vehicle that passes through a main frame 12 extending obliquely rearward and downward from a top tube 11 and downwards. The pivot plate 13 installed on the rear end of the main frame 12 in an extended manner supports the power unit 18. The power unit 18 is composed of the engine 16 and the transmission 17. The oil tank 23 is installed on the rear of the main frame 12. On the left and right paired rear frames 21, 22 (only the symbol 21 on the front side is shown.) extending obliquely upward, the trunk 24 is installed on the fuel tank 23 and the rear frames 21, 22, A tandem seat 26 is attached to the trunk 24 in a freely op...

Abstract

The invention miniaturizes a pivot plate and to enhance the rigidity by improving a frame structure of a motorcycle. The motorcycle comprises a main frame 12 extending backward and downward in the oblique direction from a head pipe, rear frames 21, 22 which are connected to a rear portion of the main frame 12 and extend backward and upward in the oblique direction, and an engine unit 18 supported by a lower portion of the main frame 12. A pivot pipe 114 is provided on a back side 13a of a pivot plate 13 provided on a rear lower portion of the main frame 12, and a rear fork 47 is supported by the pivot pipe 114 in a swinging manner.

Description

technical field [0001] The present invention relates to the improvement of the frame structure of a motorcycle. Background technique [0002] As everyone knows, the frame structure of the existing two-wheeled motorcycle is that the pivot plate is installed on the rear portion of the main frame, and the pivot is mounted on 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 The following content is recorded in the document, the pivot plate 17 is installed on the rear part of the main frame 13 constituting the vehicle frame, the support shaft 20 is installed on the pivot plate 17, and the rear fork 21 supporting the rear wheel can be freely 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, 18 and a connecting plate portion 19 connecting these flat plate portions 18, 18, and a s...
