Abstract
The utility model discloses a drive main reducer shell for axle, including first shell, screw rod, a damping spring, second shell, main reducer fixed mounting and lies in first shell in the second shell in the second shell, and second shell and the coaxial setting of first shell, seted up the multiunit screw on first shell, every group screw quantity is N, and N >= 3, every group screw are all along the side circumference range of first shell, all install the screw rod in every screw, in every screw rod extended to first shell, a damping spring was all connected to the screw rod end that just lies in first shell, and the one end that a damping spring kept away from the screw rod all is equipped with antiskid sheets, and antiskid sheets all offsets with the second shell is surperficial. The utility model discloses when using, carry out the vibrations meeting that power produced at main reducer when carrying out power transmission and absorbed by a plurality of damping spring for the main reducer shell remains stable under long -time function, has reduced the stress concentration phenomenon of axle housing.
Description
Technical field
This utility model relates to technical field of automobile, particularly relates to a kind of driving vehicle bridge final drive casing.
Background technology
Automobile axle housing, is the basic part installing main reducing gear, differential mechanism, semiaxis, wheel hub and suspension, and Main Function is supporting and protects main reducing gear, differential mechanism and semiaxis etc..Meanwhile, axle housing be again running gear mainly comprise one of part.Automobile axle housing can be subject to the moment that vertical load, longitudinal force, side force and these power are formed in the process used, and produces vibration under the effect being subject to various moment for a long time, it is easy to causes that some position stress of axle housing is concentrated.For this, drive vehicle bridge final drive casing it is proposed that a kind of.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and the one proposed drives vehicle bridge final drive casing.
To achieve these goals, this utility model adopts the technical scheme that
A kind of driving vehicle bridge final drive casing, including the first shell, screw rod, the first damping spring, second housing, main reducing gear is fixedly mounted in second housing, and is positioned at the first shell in second housing, and second housing and the first shell are coaxially disposed；Offering on the first shell and organize screw more, often group screw quantity is N number of, and N >=3, and often group screw is each along the first shell side circumferential array；Being respectively mounted screw rod in each screw, each screw rod extends in the first shell, and the screw rod end being positioned at the first shell is all connected with the first damping spring, and the first damping spring is equipped with Anti-skid sheet away from one end of screw rod, and Anti-skid sheet all offsets with second housing surface.
Preferably, it is crisscross arranged between two groups of often adjacent screws.
Preferably, it is arranged with the second damping spring in the first damping spring, and the vibrations coefficient of the first damping spring is more than the vibrations coefficient of the second damping spring.
Preferably, the first damping spring and screw rod are structure as a whole.
Preferably, outside the first shell, it is arranged with the 3rd shell, and between the first shell and the 3rd shell, interference fit connects.
The one that the utility model proposes drives vehicle bridge final drive casing, in use, main reducing gear is fixedly mounted in second housing, carry out power vibrations of generation when carrying out power transmission at main reducing gear to be absorbed by multiple damping springs, final drive casing is remained stable under running for a long time, decrease the stress concentration phenomenon of axle housing, extend final drive casing and benefit from the life-span.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
With reference to Fig. 1-3, a kind of driving vehicle bridge final drive casing, including the first shell 1, screw rod the 3, first damping spring 4, second housing 5, main reducing gear is fixedly mounted in second housing 5, and be positioned at the first shell 1 in second housing 5, and second housing 5 and the first shell 1 are coaxially disposed.
Offering many group screws 6 on the first shell 1, often group screw 6 quantity is N number of, and N >=3, and often group screw 6 is each along the first shell 1 side circumferential array, is crisscross arranged between two groups of often adjacent screws 6, and often group screw 6 is spaced substantially equidistant on the first shell 1.
It is respectively mounted screw rod 3 in each screw 6, each screw rod 3 extends in the first shell 1, and screw rod 3 end being positioned at the first shell 1 is all connected with the first damping spring 4, it is arranged with the second damping spring in first damping spring 4, first damping spring 4 is structure as a whole with screw rod 3, and first the vibrations coefficient of damping spring 4 more than the vibrations coefficient of the second damping spring, thus that reduces spring shakes phenomenon certainly, first damping spring 4 is equipped with Anti-skid sheet away from one end of screw rod 3, and Anti-skid sheet all offsets with second housing 5 surface, Anti-skid sheet can increase and the contact area on second housing 5 surface, anti-sliding stop.
Outside the first shell 1, it is arranged with the 3rd shell 2, and between the first shell 1 and the 3rd shell 2, interference fit is connected.In use, main reducing gear is fixedly mounted in second housing 5, carry out power vibrations of generation when carrying out power transmission at main reducing gear to be absorbed by multiple damping springs, final drive casing is remained stable under running for a long time, decrease the stress concentration phenomenon of axle housing, extend final drive casing and benefit from the life-span.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model.
