Abstract

The invention aims at proving a vehicle body framework made of press working drip mouldings of a two-wheeled motorcycle. The vehicle body framework not only satisfies a requirement of light weight but also has relatively high rigidity. On the vehicle body framework, a main framework (22) is composed of a straight line extension portion (27) and a bending portion (28) which bends from a rear end of the straight line extension portion (27) and is extended downwards. A rear framework (23) is a part whose head end is connected with the left and right lateral surfaces of the bending portion (28) in a vehicle width direction and a part that is extended backwards. Reinforcement members (77, 78) that are generally rectangular in an overlook view are disposed between the bending portion (28) and a front portion inner surface of the rear framework (23). Front edges of the reinforcement members (77, 78) are connected with a rear surface of the bending portion (28) and a pivot framework portion (24) respectively.

Description

technical field [0001] The present invention relates to an improvement of a body frame of a motorcycle. Background technique [0002] In recent years, many body frames of two-wheeled motorcycles are formed by joining plates formed by press working together to form a skeleton of the body frame, and forming a body frame structure by such a skeleton (for example, refer to Patent Document 1 ( Figure 5 )). [0003] In Patent Document 1 Figure 5 It shows the exploded structure diagram of the body frame, which can be referred to: the two-wheeled motorcycle (21) (numbers in brackets are the symbols recorded in Patent Document 1, the same below) mainly includes the main frame extending in the front and rear directions of the body (30). The main frame (30) is a structure with a closed section (also called a closed structure). The members ( 32 ) are formed by joining in the vertical direction. [0004] A middle part (50) with a pivot part extends downward from the middle part of t...
