Abstract
The utility model discloses a kind of automobile rear axle structure, belong to auto-parts field.It comprises semiaxis, axle tube and rear-axle casing, described axle tube is set in rear-axle casing, described half-axile sleeve is located in semiaxis pipe box, and semiaxis pipe box is stretched out in semiaxis one end, described rear-axle casing comprises the first housing, the second housing and speed reducer assembly, adopt between described axle tube and speed reducer assembly and be welded to connect, first housing and the second inner walls offer groove, described groove and axle tube and speed reducer assembly weld in the same plane, establish the reinforcement steel plate of annular in described groove.Described reinforcement steel plate is the senior carbon chromium alloyed steel that strength high toughness is good, by strengthening the effect of steel plate, avoiding traditional rear-axle casing and occurring in axle tube and the speed reducer assembly weld situation about even rupturing that ftractures, the safety of increase automobile and quality.
Description
Technical field
The utility model relates to auto-parts field, particularly relates to automobile rear axle structure.
Background technology
Nowadays the speed of a motor vehicle of automobile is more and more faster, and load carrying ability carries larger and larger, also more and more higher to the requirement of vehicle rear-axle housing.Vehicle rear-axle housing mainly adopts forging forming and welding fabrication, and the technological requirement of forging forming is high, and cost is high, even and if adopt the rear-axle casing partial failure of forging forming, whole rear-axle casing also must be scrapped, and does not very have cost performance.So lilliput car many employings welding fabrication of China manufactures rear-axle casing, namely adopt between axle tube and speed reducer assembly and be welded to connect, come cost-saving with this.Adopt the rear-axle casing of welding fabrication to reduce at axle tube and speed reducer assembly weld intensity, in actual environment, be again the region that stress is larger herein, often can because Lack of support, and insufficient strength, rear-axle casing ftractures herein and even ruptures.
Utility model content
Technical problem to be solved in the utility model is: propose a kind of automobile rear axle structure, it solves the problem of automobile rear axle structure insufficient strength.
The utility model technical solution problem adopts following technical scheme:
A kind of automobile rear axle structure, comprise semiaxis, axle tube and rear-axle casing, described axle tube is set in rear-axle casing, described half-axile sleeve is located in semiaxis pipe box, and semiaxis pipe box is stretched out in semiaxis one end, described rear-axle casing comprises the first housing, second housing and speed reducer assembly, described first housing, second housing is symmetrically welded integral up and down, notch is offered respectively in the middle of described first housing and the second housing, described notch coordinates formation cavity, described speed reducer assembly is positioned at described cavity, adopt between described axle tube and speed reducer assembly and be welded to connect, first housing and the second inner walls offer groove, described groove and axle tube and speed reducer assembly weld in the same plane, the reinforcement steel plate of annular is established in described groove.
Preferably, described groove realizes seamless combination with reinforcement steel plate.
Preferably, described reinforcement steel plate is the senior carbon chromium alloyed steel that strength high toughness is good.
The beneficial effects of the utility model are: by strengthening the effect of steel plate, the bearing capacity of back axle gets a promotion, and intensity is improved, and avoid and to ftracture situation about even rupturing at weld, also improve safety and the quality of car load.
Accompanying drawing explanation
Fig. 1 is that the utility model master looks cross-sectional view.
Number in the figure: 1 is semiaxis, 2 is axle tube, and 3 is rear-axle casing, and 4 is the first housing, and 5 is the second housing, and 6 is speed reducer assembly, and 7 for strengthening steel plate, and 8 is groove.
Detailed description of the invention
In order to technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, the utility model proposes a kind of automobile rear axle structure, comprise semiaxis 1, axle tube 2 and rear-axle casing 3, described axle tube 2 is set in rear-axle casing 3, described semiaxis 1 is set in semiaxis pipe box 2, and semiaxis pipe box 2 is stretched out in semiaxis 1 one end, described rear-axle casing 3 comprises the first housing 4, second housing 5 and speed reducer assembly 6, described first housing 4, second housing about 5 is symmetrically welded integral, notch is offered respectively in the middle of described first housing 4 and the second housing 5, described notch coordinates formation cavity, described speed reducer assembly 6 is positioned at described cavity, adopt between described axle tube 2 and speed reducer assembly 6 and be welded to connect, first housing 4 and the second housing 5 inwall offer groove 8, described groove 8 and axle tube 2 and speed reducer assembly 6 weld in the same plane, the reinforcement steel plate 7 of annular is established in described groove 8.
When specific design, described groove 8 realizes seamless combination with reinforcement steel plate 7, increases rear-axle casing intensity herein.
When specific design, described reinforcement steel plate 7 is the senior carbon chromium alloyed steel that strength high toughness is good, increases rear-axle casing intensity herein and toughness.
The utility model proposes a kind of automobile rear axle structure.Compare traditional automobile rear axle structure, the utility model offers groove 8 on rear-axle casing 3 inwall that axle tube 2 is corresponding with speed reducer assembly weld, install the reinforcement steel plate 7 of annular additional, the senior carbon chromium alloyed steel that reinforcement steel plate 7 adopts strength high toughness good is made, strengthen steel plate 7 and realize seamless combination with rear-axle casing 3, by the effect of this reinforcement steel plate 7, the bearing capacity of back axle gets a promotion, intensity is improved, avoid and to ftracture situation about even rupturing at weld, also improve safety and the quality of car load.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
