Light weight has been widely used for automobile industry lightweight product.Housing part in the speed changer of my company high-volume
Using aluminum alloy materials.Rear cover housing is the housing part of transmission assembly stress maximum, is turned round to improving the specified input of gearbox
Square is most important.In order to which it is made to meet the manufacturing condition of die-casting process, need to carry out again original aluminium alloy rear cover housing
Design reduces gearbox weight, improves casing rigidity, production efficiency, saves production cost.
Utility model content
After a kind of aluminium alloy of structural strengthening the shortcomings that the above-mentioned prior art, is provided
Lid housing disclosure satisfy that the manufacturing condition of die-casting process.
In order to achieve the above objectives, the utility model is achieved using following technical scheme：
A kind of aluminium alloy rear cover housing of structural strengthening is engaged including being set to the positive rear cover of rear cover housing with cover board
Face, and height is at least 151mm；The back side of rear cover housing is groove-like, and outer edge is provided with thickness and is up to 10mm
Rear cover and case of transmission composition surface；Top in groove is provided with lightening grooves；And the thickness of the side wall of rear cover housing is most
For 6mm.
The utility model, which further improves, to be：
Outside muscle is provided on the lateral wall of rear cover housing, outside muscle is trapezium structure.
Inside muscle is provided at the groove slot bottom edge of rear cover back side of shell, and is in contact with the madial wall of the groove,
Inside muscle is triangular structure.
There are two rear cover Auxiliary supports for the setting of rear cover housing upper side, and two rear cover Auxiliary supports and rear cover back side of shell are same
The side of side is cambered surface, other three sides are plane.
Upper table gluten and jackshaft orifice ring muscle are radially provided on rear cover housing around rear cover and cover board composition surface.
The upper table gluten and jackshaft orifice ring muscle are in the crisscross setting in rear cover housing front.
Compared with prior art, the utility model has the advantages that：
The utility model is due to changing the side thickness of rear cover housing and reducing rear cover and the thickness on case of transmission composition surface
The design in plump region spent and lightening grooves is used to eliminate rear cover housing, makes it meet the requirement of die-casting process, and eliminate
Die-casting process casts shrinkage cavity risk during rear cover housing so that the overall weight of rear cover housing is reduced to by original 6.46kg
5.41kg reduces 16.3%；By change the thickness of rear cover and cover board composition surface and employ reinforcement (upper table gluten, in
Countershaft orifice ring muscle, outside muscle and inside muscle) design, the strength character of 8 grades of aluminium alloy rear cover housings is made to promote 17.5%, it is full
The assembly performance requirement under the harsh environments of foot speed changer；It and, can as a result of the design of rear cover Auxiliary support
Fixture is made to pick up rear cover housing more convenient.
