Description of the invention () (please read the back-end precautions # fill out this page) The present invention is about a single rocking engine of an automatic two-wheeled vehicle, especially the engine and transmission The box is integrated, and it can be mounted on the car's body freely by shaking up and down. A single swing engine has been used on a small automatic two-wheeled vehicle, which is equipped with, for example, an engine and a transmission box. The crankshaft of the engine is supported on one end of the transmission box, while the other end is supported on the axle of the rear wheel. The crank shaft and the axle are linked in a transmission box by a transmission mechanism, the engine and the transmission box are integrated, and they are planted in the vehicle body so as to be able to rock up and down, forming part of the suspension device. In such an automatic two-wheeled single-swing engine, if the output of the engine becomes larger, the heat output of the power transmission mechanism also becomes larger. Since the power transmission mechanism and the transmission box are installed in the transmission box cover, they are inside Heat is not easy to dissipate. Therefore, although an air inlet is formed in the gearbox cover and the air is introduced into the interior to reduce heat retention, water will invade from the air inlet formed on the gearbox cover when walking on rainy days. Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. Although the transmission box and the transmission box cover have a certain degree of anti-sound effect on the internal action, vibration sound will be generated from the box itself. The mood of the occupants will produce bad shadows, so there are those who use the soundproof cover to cover the transmission box cover as a whole. Between the peripheral wall of the soundproof cover and the transmission box cover, although the vibration of the soundproof cover can be reduced through the cushioning material, at this time, a notch portion needs to be provided in a part of the cushioning material to form an air introduction opening, However, this notch formed in a part of the cushioning material may damage the effect of preventing vibration of the soundproof cover.

The peripheral wall 77a is curved inwardly, and covers the entire outer side of the outer side wall portion 16a of the transmission case cover 16. The soundproof cover 77 is formed of synthetic resin, etc., and its peripheral wall 77a penetrates through the ring-shaped cushioning material 78, and is screwed and fixed to the peripheral wall 16b of the transmission case cover 16 by bolts 79, and is integrated with the transmission case cover 16. In this way, the soundproof cover 77 can cover the outer surface of the outer side wall portion 16a of the transmission case cover 16, and can reduce the vibration sound generated by the vibration of the transmission case 16 body to the outside of the vehicle. Furthermore, although the soundproof cover 77 is made of synthetic resin, it is not limited to this, and it may be made of gold alloy such as light alloy. A part of the peripheral wall 16b of the transmission case cover 16 whose front direction of the vehicle auxiliary travels is extended outward, and an air introduction window portion 80 is formed on the extension part 16c, and the transmission case cover 16 including the extension part 16c is formed The whole. Cover with soundproof cover 77. A rib 25a is integrally formed on the engine cover 25, and the rib 25a is virtually opposed to a portion 77b of the soundproof cover 77 covering the extension portion 16c of the transmission case cover 16. Furthermore, the extended portion 16c is formed in a protruding shape, and an air introduction window portion 80 is formed. At the central portion of the cylindrical portion 16f, a rib 16g extends from the peripheral wall 16b. Therefore, air enters between the portion 77b of the extension portion 16c of the transmission case cover 16 and the rib 25a by the soundproof cover 77. In addition, when walking on rainy days, even if the water flows along the fluid tank cover 16, since the rib 16g extending from the extension portion 16c is pseudo-connected to the central portion of the cylindrical portion 16f, the flow of water can be prevented by the chute portion 16f Moreover, it is possible to prevent the air introduction window portion 80 from intruding into the interior.

Description of the invention () Used to guide the air drawn in from the air introduction window 80 into the transmission case 14; the air is further guided by the air passage 81 to the air suction part 82 formed in the transmission case cover 16 The air suction portion 82 can be introduced into the transmission case 14. The air suction portion 82 is pseudo: the window portion 83, formed in the transmission case cover 16, and located opposite to the driving pulley 56 of the V-belt automatic transmission 55; the element 84, pseudo covering the window portion 83; the cover body 85, formed to hold the element 84, and the cover 85 is bolted to the support shaft 61 with a bolt 86. The cover 85 fixes the element 84 by its rib 85a, and a window 85b is formed between the ribs 85a, and air passes from the window 85b through the element 84, and passes through the window 83 formed on the Fu box cover 16, and Import inside. At the rear of the peripheral wall 16b of the transmission case cover 16, openings 16d and 16e are formed, and the openings 16d and 16e can be discharged outward through the air discharge passage 87 formed by the transmission case cover 16 and the soundproof cover 77. The air guided by the air discharge passage 87 is discharged to the outside from the opening 88 of the buffer 78 without the soundproof cover 77. Printed by the Beigong Consumer Cooperative of the Bureau of Standards and Economy of the Ministry of Economic Affairs so that a part of the peripheral wall 16b of the transmission case cover 16 extends outward, and an air introduction window 80 is formed in the extension portion 16c; including the extension portion 16 The entire transmission box cover 16 of c is covered with a soundproof cover 77; and between the peripheral wall 77b of the soundproof cover 77 and the peripheral wall 16b of the transmission box cover 16, a cushion 78 is filled: by forming the structure of the air introduction window 80, The cushion material 78 is not cut off, so that the effect of preventing the vibration of the soundproof cover 77 is not impaired. Furthermore, the air is introduced through the air introduction port formed in the extension part 16c; the air is introduced through the air suction part 82 formed in the transmission case cover 16 through the air passage 81 formed between the soundproof cover 77 and the transmission case cover 16 Within the gearbox 14; 81. 7. 20,000¾ (I!)

Description of the invention () Air is introduced into the transmission box 14 to reduce the heat retention phenomenon. Furthermore, the sound introduction cover 77 is used to cover the air introduction window 80, and a cylindrical air introduction window portion 80 is formed in the extension portion 16c, therefore, water can be prevented from intruding into the interior. As described above, the present invention is pseudo, so that a part of the peripheral wall of the transmission box cover extends outward; The extension part forms an air introduction window part; the whole transmission case cover containing the extension part is covered with a soundproof cover; an air introduction window part is formed between the sound insulation cover peripheral wall and the transmission case cover peripheral wall through a buffer material; thereby , There is a cut-out part in a part of the buffer material. Air, so that the effect of preventing the vibration of the soundproof cover is not impaired. Furthermore, the air formed in the extension portion is introduced into the window to guide the air; the air passage formed between the soundproof cover and the transmission case cover is formed from The air is sucked into the transmission box cover and the air is introduced into the transmission box. Therefore, the air is introduced into the transmission box to reduce heat retention, and the air introduction window is covered with a soundproof cover, and water can be prevented from extending out. The part enters the interior. A brief description of the plaque. Figure 1.
