Abstract
The utility model discloses a lightweight integrated main reducer housing comprising a housing, wherein the housing is provided with a driving cylindrical gear and a driven cylindrical gear for a first-order reduction and a driving bevel gear and a driven bevel gear for a second-stage reduction therein. In order to solve the oil leakage fault of a connecting oil seal in the main reducer and achieve lightweight of main components in an axle, the utility model optimally designs the lightweight integrated main reducer housing; wherein the main reducer housing not only can ensure supporting type, arranging method and supporting rigidity of a transmission gear in the main reducer, but also can reduce the weight of the housing by about 10 kg; in addition, the main reducer housing also cancels a connecting bolt and the connecting oil seal required by a traditional combined split type main reducer housing, thereby thoroughly preventing the oil leakage fault at a connecting part of the main reducer housing; and the housing contains the driving cylindrical gear and the driven cylindrical gear for the first-order reduction and the driving bevel gear and the driven bevel gear for the second-stage reduction therein, so that an oil duct design in the main reducer housing is simple and reasonable, thereby ensuring that lubricating oil can flow smoothly. Therefore, the lightweight integrated main reducer housing of the utility model has the advantages of simple structure, low cost, and long service life; in addition, the lightweight integrated main reducer housing not only solves the oil leakage fault of the connecting oil seal in the main reducer, but also achieves lightweight of the main components in the axle.
Description
Technical field
The utility model relates to a kind of shell that subtracts, and specifically relates to a kind of lightweight integral type main reducing gear and subtracts shell, belongs to automotive field.
Background technique
Main reducing gear is one of primary component on the vehicle bridge, and its final drive casing is the main parts size on the main reducing gear, and it will meet the supporting type and the allocation method of the driving gear in the main reducing gear when design, and is unaffected with the support stiffness of guaranteeing driving gear.The final drive casing of traditional double reduction is made up of two big housings, i.e. the driving and driven cylindrical gears of one-level deceleration is placed in the housing, and the driving and driven bevel gear of double reduction is placed in the housing, is split.More than the split type connection that subtracts between the shell of combination need add bolt and oil sealing; Because of oil sealing is an easily damaged parts; Early stage easily the damage causes fault, and when dismounting, needs whole main reducing gear is taken apart and could be changed, and increased maintenance difficulty; Therefore we have carried out optimal design to final drive casing, change integral type into.
The model utility content
To the deficiency that existing technology exists, the utility model technical problem to be solved is to provide a kind of lightweight integral type to subtract shell; Simple in structure, with low cost, long service life; Solve the oil leakage fault that connects oil sealing in the main reducing gear, reached the lightweight of main parts size in the vehicle bridge simultaneously.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of lightweight integral type subtracts shell, and it comprises a housing; Be provided with the driving and driven cylindrical gears of one-level deceleration and the driving and driven bevel gear of double reduction in the said housing.
Optimize, above-mentioned a kind of lightweight integral type subtracts shell, and the wall of the mounting point of its driving and driven bevel gear is provided with oil leab.
Optimize, above-mentioned a kind of lightweight integral type subtracts shell, and its driving and driven bevel gear is the hyperboloid bevel gear.
The utility model is for solving the oil leakage fault that connects oil sealing in the main reducing gear; Reach the lightweight of main parts size in the vehicle bridge simultaneously; Optimal design wheel quantize integral type and subtract shell, this is novel to subtract supporting type, allocation method and the support stiffness that shell can not only guarantee driving gear in the main reducing gear, also case weight is compared and has been reduced about 10kg; Cancelled split type required connecting bolt of shell and the oil sealing of subtracting of traditional combination, the main oil leakage fault that subtracts the joint has thoroughly been effected a radical cure.This housing is contained within the driving and driven cylindrical gears of one-level deceleration and the driving and driven bevel gear of double reduction wherein; It is reasonable to subtract shell internal oil channel simplicity of design, has guaranteed that the circulation of lubricant oil is freely suitable, simple in structure; With low cost; Long service life has solved the oil leakage fault that connects oil sealing in the main reducing gear, reaches the lightweight of main parts size in the vehicle bridge simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is that a kind of lightweight integral type subtracts shell, and it comprises a housing 1; Be provided with driving and driven cylindrical gears 2 that one-level slows down and 3 and the driving and driven bevel gear 4 and 5 of double reduction in the said housing 1.The wall of said driving and driven bevel gear 4 and 5 mounting point is provided with oil leab 6.Said driving and driven bevel gear 4 and 5 is the hyperboloid bevel gear.The utility model is for solving the oil leakage fault that connects oil sealing in the main reducing gear; Reach the lightweight of main parts size in the vehicle bridge simultaneously; Optimal design wheel quantize integral type and subtract shell, this is novel to subtract supporting type, allocation method and the support stiffness that shell can not only guarantee driving gear in the main reducing gear, also case weight is compared and has been reduced about 10kg; Cancelled split type required connecting bolt of shell and the oil sealing of subtracting of traditional combination, the main oil leakage fault that subtracts the joint has thoroughly been effected a radical cure.This housing is contained within the driving and driven cylindrical gears of one-level deceleration and the driving and driven bevel gear of double reduction wherein; It is reasonable to subtract shell internal oil channel simplicity of design, has guaranteed that the circulation of lubricant oil is freely suitable, simple in structure; With low cost; Long service life has solved the oil leakage fault that connects oil sealing in the main reducing gear, reaches the lightweight of main parts size in the vehicle bridge simultaneously.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
