Abstract
The utility model provides a heavy truck driving axle housing, its characterized in that: the driving axle housing is an integrally formed casting; the driving axle housing comprises a left half shaft, an axle housing body and a right half shaft which are sequentially connected from left to right; a first transition connecting section is arranged at the joint of the left half shaft and the axle housing body; and a second transitional connecting section is arranged at the joint of the right half shaft and the axle housing body. The utility model discloses a drive axle housing simple structure, light in weight, security performance height, can avoid lubricating oil to leak.
Description
Technical Field
The utility model relates to an automobile manufacturing technical field, especially a heavy truck driving axle housing.
Background
In the prior art, the driving axle housing of the heavy truck shown in the attached drawing 1 comprises an axle housing body 1 ' and 2 axle sleeve pipes 2 ' at two ends, the axle sleeve pipes 2 ' are connected with the axle housing body 1 ' in an interference fit mode, but the interference fit surface is unreliable, so that the situation of failure in fit can occur, the axle sleeve pipes 2 ' are integrally fallen off, and safety accidents occur. On the other hand is owing to machining error, and the fitting surface between axle housing body 1 'and the axle sleeve 2' still can lead to the condition that lubricating oil in the axle housing leaked owing to sealed not good, and moreover, above-mentioned structure is complicated, and whole quality is great, is unfavorable for the lightweight of heavy truck.
SUMMERY OF THE UTILITY MODEL
To the problem in the background art, the utility model provides a heavy truck driving axle housing to among the solution prior art, heavy truck driving axle housing is dangerous, easy oil leak, problem that weight is big.
The utility model aims at realizing through the technical scheme, it is including:
heavy truck transaxle case, its innovation point lies in: the driving axle housing is an integrally formed casting; the driving axle housing comprises a left half shaft, an axle housing body and a right half shaft which are sequentially connected from left to right; a first transition connecting section is arranged at the joint of the left half shaft and the axle housing body; and a second transitional connecting section is arranged at the joint of the right half shaft and the axle housing body.
As optimization, the first transition connecting section and the second transition connecting section are both conical; the outer diameter of the first transition connecting section is gradually reduced from the axle housing body to the left half shaft; the external diameter of second transitional coupling section reduces from axle housing body to half axle gradually to the right side.
Due to the adoption of the technical scheme, the utility model discloses following advantage has: because transaxle case is integrated into one piece, left semi-axis, axle housing body and right semi-axis three are a whole, are difficult for throwing away each other, have set up conical transitional coupling section in the junction of three in addition, have further reduced stress concentration, have improved transaxle case's bulk strength, and the security improves greatly, does not have the gap between the three simultaneously, avoids axle housing intracavity lubricating oil to leak, and the transaxle case of this kind of an organic whole structure simple structure moreover, and weight is lighter, is favorable to putting in order the car lightweight.
Drawings
The drawings of the present invention are described below.
FIG. 1 is a schematic structural diagram of a transaxle case of the prior art;
fig. 2 is a schematic structural diagram of the present invention.
In the figure: 1. a left half shaft; 2. an axle housing body; 3. a right half shaft; 4. a first transitional coupling section; 5. a second transitional coupling section.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 2, the heavy truck transaxle case is an integrally formed casting; the driving axle housing comprises a left half shaft 1, an axle housing body 2 and a right half shaft 3 which are sequentially connected from left to right; a first transition connecting section 4 is arranged at the joint of the left half shaft 1 and the axle housing body 2; and a second transition connecting section 5 is arranged at the joint of the right half shaft 3 and the axle housing body 2. The first transition connecting section 4 and the second transition connecting section 5 are both conical; the outer diameter of the first transition connecting section 4 is gradually reduced from the axle housing body 2 to the left half axle 1; the outer diameter of the second transitional connecting section 5 is gradually reduced from the axle housing body 2 to the right half shaft 3.
