Abstract
The utility model discloses the case of transmission of a kind of low noise high intensity, described case of transmission one end is big, one end is little, overall tapered, the outer wall of described case of transmission is provided with some walings being distributed in divergent shape, the middle part of described case of transmission outer wall is provided with at least three outer modal circumferential stiffening ribs, the middle part of case of transmission inwall is provided with at least three and outer modal circumferential stiffening rib interior modal circumferential stiffening rib one to one, in described transmission case body, two installing holes around big side are provided with some radial reinforced ribs being distributed in divergent shape.On the premise of guaranteeing case of transmission intensity, alleviate the weight of case of transmission, reduce material cost and noise.
Description
Technical field
This utility model relates to the structure of auto parts and components structure, particularly case of transmission.
Background technology
Existing automobile speed variator, it is common that one end is big, one end is little, overall tapered.Whole for improving
Body intensity, often uses and sets up some walings being distributed in divergent shape on case of transmission outer wall,
Improve the thickness of case of transmission simultaneously.There is weight big, material cost is high, the problem that noise is big.
Utility model content
On the premise of this utility model aims to ensure that case of transmission intensity, alleviate the weight of case of transmission
Amount, reduces material cost and noise.
To this end, the technical scheme that this utility model is used is: the transmission case of a kind of low noise high intensity
Body, described case of transmission one end is big, one end is little, overall tapered, outside described case of transmission
Being provided with some walings being distributed in divergent shape on wall, the middle part of described case of transmission outer wall sets
Being equipped with at least three outer modal circumferential stiffening ribs, the middle part of case of transmission inwall is provided with at least three and outer shroud
To reinforcement one to one in modal circumferential stiffening rib, in described transmission case body, around the two of big side
Installing hole is provided with some radial reinforced ribs being distributed in divergent shape.
Preferred as such scheme, the height of every described waling is by the small end of case of transmission
It is gradually increased to the outer modal circumferential stiffening rib of the last item, by the outer modal circumferential stiffening rib of the last item to case of transmission
Big end the most constant.Optimization molding, improves the coordination aesthetic property of monnolithic case further.
The beneficial effects of the utility model: by setting up at least three in the middle part of the inside and outside wall of case of transmission
Bar modal circumferential stiffening rib, utilizes water ripples to run into the propagation principle of barrier, reduces noise；Outer hoop is strengthened
Muscle is crisscross with waling, the radial reinforced rib that the coupling collar two installing holes around big side are arranged,
Significantly improve the bulk strength of case of transmission, correspondingly, the thickness of case of transmission can be reduced, from
And save material cost, alleviate weight.
Accompanying drawing explanation
Fig. 1 is schematic diagram one of the present utility model.
Fig. 2 is schematic diagram two of the present utility model.
Detailed description of the invention
Below by embodiment and combine accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 Fig. 2, the case of transmission of a kind of low noise high intensity, case of transmission one
End is big, one end is little, overall tapered.The outer wall of case of transmission is provided with and some divides in divergent shape
The waling 1 of cloth.
The middle part of case of transmission outer wall is provided with at least three outer modal circumferential stiffening ribs 2, in transmission case body
The middle part of wall is provided with at least three and outer modal circumferential stiffening rib 2 interior modal circumferential stiffening rib 3 one to one.Becoming
In speed device housing, two installing holes around big side are provided with some radial reinforced ribs being distributed in divergent shape
4.Holding greatly relative small end, intensity is slightly aobvious not, it is therefore necessary to increase radial reinforced rib 4 big end, little
End then need not.
Preferably, the height of every waling 1 by the small end of case of transmission to the last item outer shroud
It is gradually increased to reinforcement 2, by the last item outer modal circumferential stiffening rib 2 holding greatly highly to case of transmission
Constant.
Claims (2)
