Abstract
The utility model provides a pneumatic control unit housing for a gearbox, characterized in that the material is magnesium alloy. The density of the magnesium alloy is 23% of that of the steel, the yield strength of the magnesium alloy is roughly the same as the aluminium alloy, just slightly less than the carbon steel. Therefore under the same strength and rigidity, magnesium alloy is used as material of the pneumatic control unit housing of the gearbox, the weight is reduced by about 75%.
Description
Technical field
The utility model relates to commercial car gearshift case air-operated control device housing.
Background technique
Recent two decades comes, the sustainable growth of world car output, and average growth rate per annum is 2.5%.The automobile industry development degree is one of important symbol of a national development degree, and metallic material is the important foundation of automobile industry development.For energy-conservation and environmental protection requirement, the Automobile Design brainstrust alleviates vehicle weight by every means, to reach the double effects that reduces gasoline consumption and discharge amount of exhaust gas.Present commercial car gearshift case air-operated control device housing still adopts cast iron, and weight is big, and the casting surplus is big, the processing cost height.
Summary of the invention
For under the condition of proof strength and rigidity, alleviate the weight of gearshift case air-operated control device housing, the utility model proposes a kind of gearshift case air-operated control device housing.
For this reason, the technical solution of the utility model is: the gearshift case air-operated control device housing is characterized in that: material is a magnesium alloy.
Beneficial effect: the density of magnesium alloy is 23% of steel, and the yield strength and the aluminum alloy of magnesium alloy are about the same, only is lower than carbon steel slightly.Therefore under identical strength and stiffness situation, with the material substitution cast iron of magnesium alloy as the gearshift case air-operated control device housing, weight reduces about 75%.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The moving Effector housing 1 of change gas speed case as shown in Figure 1, its material is a magnesium alloy.Gearshift case air-operated control device housing 1 is a die castings.The trade mark that magnesium alloy preferably adopts is AZ91D, and the also adoptable trade mark is AS41B.
Claims (3)
1, gearshift case air-operated control device housing is characterized in that: material is a magnesium alloy.
2, gearshift case air-operated control device housing according to claim 1 is characterized in that: the trade mark of described magnesium alloy is AZ91D.
3, gearshift case air-operated control device housing according to claim 1 is characterized in that: described gearshift case air-operated control device housing is a die castings.
