Description

[Detailed description of the invention] The superposition @ is placed on the 7th frame of the motorcycle.

As shown in Figure 511, motorcycles usually have 1 piece of material 2 (- for the sake of machining, Tanibashi material, etc.)
I am so patient. And, for defective rice, round bye 1 was used as frame byte 1, but it has been recently since - during the period of good strength.

1112WIIIJE 9 times as shown in corner by 1 to be used.

This square pie 13 is made of a general electric resistance such as am, alsago, and Il, and has a square shape.

In other words, using the half cell on one side of this quadrilateral, #
The above-mentioned t-fold strength is intended to be reduced, but when machining this square pipe 3Kjlll, the following problems are solved as if it were just a matter of sewing.

Namely.

■ The workability of square pipes is poor, and AM work is not easy.

ψ--gearing process II (Fig. 1 OA-Yen 1-) causes distortion and strain 4 (see Fig. 43 #Y), which causes a decrease in frame 1 (0 strength).

(J) The outer fit of the product may be felt.

etc.

This shield is intended to solve the 7th rule of Zeng's two-wheeled army [11], and to use the square pie 1 to provide at least 4 of the 7th point of the friend The circle 11 is marked with an indentation t, which serves as a replacement image.

Based on the superposition 110 J111 kj 14 diagram below, in this case, the square pie ysot) (tomge 1 work part t) 8 mK, <bami St smooth and damp sP @, this ``E7 Ray 5ik is formed.

The deformation and strain during ridge processing is mainly in the compression direction, and in order to avoid a misfire, it is necessary to provide at least 18K < 5t & stiffening in the ridge processing area (from Fig. 3). A strain force of 4 is generated and becomes 1^, which becomes K.SP, if a concave force is provided in the 4rIi eclipse as in this example, the frame 10m1lli1minO outside @O-1 Even if the friend leaves both sides and *4 mFi, -1's cross section and 6, it is possible to lie in the same way.

Of course - 17 les 1 ^ A square vibrator with 41 tons of food body TC (
There is no blind meeting with the Jin that can be made up of L-san, deformation during T*age processing, and strain 4.
It doesn't matter how big or small it is.

According to the queen, Jin and T Hideaki,
*Due to the machining process, the 7-frame Ryo OM [Kuraisomoto's opinion is that it is possible to decide on 1 and 9. Furthermore, it is important as -1. Appearance room l11i
