Abstract
The utility model provides a lightweight transmission housing, include that the casting of the non-atress surface at the casing has a plurality of to subtract heavy groove, the cross section that subtracts the heavy groove sets up to regular hexagon. The utility model discloses a casting a plurality of heavy grooves that subtract in the non-atress surface of casing, the cross section that will subtract the groove simultaneously sets up to regular hexagon, because of regular hexagon structure bearing capacity is stronger under equal atress condition, fatigue resistance is better, non-deformable and difficult fracture, so this kind of regular hexagon structure subtract heavy groove not only can increase the casing surface area, increase heat dispersion, can reach the purpose that alleviates casing weight moreover.
Description
Technical Field
The utility model belongs to the technical field of the gearbox, specifically relate to a lightweight gearbox housing.
Background
Under the background of global climate change, environmental pollution and increasingly aggravated energy crisis, energy conservation and emission reduction become important problems faced by the automobile industry. The light weight of the automobile is one of important ways for realizing energy conservation and emission reduction of the automobile, and the light weight of the automobile is a consensus in the automobile industry. The automobile is light, so that the rolling resistance, the acceleration resistance and the climbing resistance of the automobile can be reduced, the fuel consumption can be reduced, and the exhaust emission of the automobile can be reduced; but also can directly improve the specific power of the automobile and improve the dynamic performance of the automobile. Therefore, the light weight of the automobile is one of the important technical measures for effectively reducing the oil consumption, reducing the emission and improving the dynamic performance of the automobile.
The transmission housing is required to have sufficient rigidity and strength because it is required to seal, mount support parts, and store lubricating oil, and to withstand various varying loads. In the development process of the light weight of the gearbox shell, the wall thickness of the shell cannot be simply reduced, and the product performance must be met.
SUMMERY OF THE UTILITY MODEL
To the above prior art, the to-be-solved technical problem of the utility model is to provide a lightweight transmission housing.
In order to solve the technical problem, the utility model provides a lightweight transmission housing, include that the casting has a plurality of to subtract heavy groove at the non-atress surface of casing, the cross section that subtracts the heavy groove sets up to regular hexagon.
More preferably, the depth of the weight-reducing groove is set to be 1 mm.
Compared with the prior art, the beneficial effects of the utility model are that: through a plurality of heavy grooves that subtract of casting on the non-atress surface at the casing, will subtract the cross section in heavy groove simultaneously and set up to regular hexagon, because of regular hexagon structure bearing capacity is stronger under equal atress condition, fatigue resistance is better, non-deformable and difficult fracture, so this kind of regular hexagon structure subtract heavy groove not only can increase housing surface area, increase heat dispersion, can reach the purpose that alleviates casing weight moreover.
Drawings
Fig. 1 is the utility model relates to a structural schematic of lightweight transmission housing.
Fig. 2 is a cross-sectional view of the weight-reducing regular hexagonal slot of fig. 1.
Illustration of the drawings: 1-regular hexagon weight reduction grooves and 2-reinforcing ribs.
Detailed Description
The invention will be further described with reference to the drawings and preferred embodiments.
As shown in fig. 1 and 2, the structural schematic diagram of a light-weight transmission housing according to the present invention is that a plurality of regular hexagonal weight-reducing grooves 1 with a certain depth are cast on the non-stressed surface of the housing, and a reinforcing rib 2 formed by the wall thickness before weight reduction is retained between the grooves. The utility model discloses in, the thickness of above-mentioned casing is 4mm, and the thickness that regular hexagon subtracts heavy groove 1 is 3mm, and the degree of depth that regular hexagon subtracts heavy groove 1 is 1mm promptly, and this just makes the weight ratio of subtracting of whole casing about 10%, and subtract the casing intensity after heavy still can satisfy the strength requirement.
The utility model discloses a casting a plurality of regular hexagons at the non-atress surface of casing and subtracting groove 1, because of regular hexagon structure bearing capacity is stronger under equal atress condition, fatigue resistance is better, non-deformable and difficult fracture, space and material can be saved to this kind of regular hexagon structure simultaneously, so this kind of regular hexagon structure subtract heavy groove not only can increase housing surface area, increase heat dispersion, reach lightweight purpose, can use minimum material to obtain the most space moreover.
The foregoing merely illustrates preferred embodiments of the present invention, which are described in considerable detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, modifications and substitutions can be made, which are all within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
Claims (2)
1. A lightweight transmission housing characterized by: the shell comprises a plurality of lightening slots cast on the non-stressed surface of the shell, and the cross sections of the lightening slots are arranged to be regular hexagons.
2. A light weight transmission housing as defined in claim 1, wherein: the depth of the weight reduction groove is set to be 1 mm.
