Referring to fig. 1, the present embodiment provides a transmission, which includes a body (not shown) and a valve cover 1, wherein after the transmission is started, the body generates noise, and the noise can be transmitted to the external environment through the valve cover 1. In this embodiment, the valve body cover 1 includes a cover body 11, a first rib 12 and a second rib 13, the first rib 12 is connected to the cover body 11, the first rib 12 is distributed in a grid shape, the second rib 13 is disposed in at least a part of the grid of the first rib 12, and the second rib 13 is connected to the first rib 12.

Like this, the sound wave that the body produced is at the in-process that passes valve body lid 1, and on first muscle 12 and the second muscle 13 can be transmitted to the sound wave, the partial energy of sound wave can be consumed to first muscle 12 and the second muscle 13 for the sound wave is difficult to pass lid 11, thereby can reduce the noise that transmits to the external environment from the body, promotes user experience.

In addition, in this embodiment, the first ribs 12 are in a grid shape, the first ribs 12 are connected to the cover 11, and the first ribs 12 can enhance the rigidity of the cover 11. Moreover, at least part of the meshes of the first ribs 12 are provided with second ribs 13, and the second ribs 13 are connected with the first ribs 12, so that the rigidity of the cover body 11 can be further enhanced. Like this, after the rigidity reinforcing of lid 11, the derailleur is at the in-process of normal work, and lid 11 is difficult to produce the vibration, can further noise abatement, promotes user experience.

It should be noted that "the second ribs 13 are disposed in at least part of the mesh of the first ribs 12" may be understood as that the second ribs 13 are disposed in part of the mesh of the first ribs 12. It is also understood that the second ribs 13 are provided in all the meshes of the first ribs 12.

Optionally, the second ribs 13 are disposed in all the meshes of the first ribs 12, so that the rigidity of the cover 11 can be greatly enhanced, and the noise can be reduced to a lower level.

Referring to fig. 1, in the present embodiment, the second ribs 13 are also in a grid shape. Like this, the rigidity of lid 11 can further be strengthened after second muscle 13 is connected with first muscle 12 for the noise is difficult to pass lid 11 and transmits out, thereby reaches noise reduction, promotes user experience's purpose.

Optionally, the first rib 12 and the second rib 13 are integrally formed, and the connection strength between the first rib 12 and the second rib 13 is high, so that the rigidity of the cover 11 can be further enhanced.

Referring to fig. 1, in the embodiment, the first rib 12 includes a plurality of first connecting ribs 121, the plurality of first connecting ribs 121 are connected to each other, the second rib 13 includes a plurality of second connecting ribs 131, the plurality of second connecting ribs 131 are connected to each other, and at least a portion of the second connecting ribs 131 is connected to at least a portion of the first connecting ribs 121.

Alternatively, each first connecting rib 121 may be individually connected with the second connecting rib 131. Alternatively, each of the second connecting ribs 131 may be individually connected with the first connecting rib 121. Alternatively, a part of the second connection ribs 131 therein is connected to a part of the first connection ribs 121 therein.

In this embodiment, the thickness value of the second bead 131 in the thickness direction of the cover 11 is smaller than the thickness value of the first bead 121. Therefore, the second connecting rib 131 can be conveniently connected in the grid of the first rib body 12, and the processing and the manufacturing are more convenient.

Similarly, in the present embodiment, the width of the second connecting rib 131 is smaller than the width of the first connecting rib 121. Therefore, the second connecting rib 131 can be conveniently connected in the grid of the first rib body 12, and the processing and the manufacturing are more convenient.

In practical use, optionally, the first connecting rib 121 and the second connecting rib 131 are both cylindrical, and the outer diameter of the second connecting rib 131 is smaller than the outer diameter of the first connecting rib 121.

Referring to fig. 1, in the present embodiment, the first rib 12 and the second rib 13 are both accommodated inside the cover 11. Like this, the noise of derailleur is produced the back, and on first muscle 12 and the second muscle 13 can be taken first to the sound wave, the energy of sound wave can in time be consumed to first muscle 12 and the second muscle 13, hinders the sound wave and passes lid 11.

In the present embodiment, a damping layer (not shown) is bonded to the outer side of the cover 11. Thus, the damping layer can further dissipate the energy of the sound wave, so that the noise transmitted to the outside of the cover 11 is reduced.

Optionally, the damping layer may be a damping paste, filled with damping glue, or the like.

Referring to fig. 2, in the present embodiment, an auxiliary groove 14 is recessed on an outer side of the cover 11, and the damping layer is attached to an inner side of the auxiliary groove 14. Thus, the auxiliary groove 14 can facilitate the attachment of the damping layer, and the damping layer is not easy to fall off the cover 11. In addition, as the damping layer is attached to the inner wall of the auxiliary groove 14, the damping layer can be prevented from being scraped by external objects, and the completeness of the damping layer is ensured.

Referring to fig. 2, in the present embodiment, the valve body cover 1 further includes a plurality of third ribs 15, the plurality of third ribs 15 are all connected to the outer side of the cover body 11, and the plurality of third ribs 15 are distributed at intervals along the circumferential direction of the auxiliary groove 14.

It can be understood that the plurality of third ribs 15 can further increase the rigidity of the cover 11, and prevent sound waves from passing through the cover 11, thereby reducing noise generated by the transmission.

In the present embodiment, a plurality of third ribs 15 are provided on the smooth surface of the outer side of the cover 11. Like this, for the condition of the lid 11 outside for smooth surface, after a plurality of third muscle bodies 15 set up, the sound wave collision is on third muscle body 15, and third muscle body 15 can consume the sound wave energy to reduce the noise that transmits the lid 11 outside, promote user experience.

The embodiment also provides an automobile, which comprises the transmission and has all functions of the transmission, the noise of the automobile is low, and the user experience can be effectively improved.

The above description is only exemplary of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
