Description
Technical field
The utility model relates to a kind of aluminum alloy bonnet housing.
Background technique
Automotive light weight technology is the most real and the most effective technical measures of current car load energy-saving and emission-reduction.Aluminum alloy because quality is light, good corrosion resistance, be easy to the features such as processing, as the ideal material of automobile loss of weight.The aluminum alloy gearbox product of my company forms seriation.Bonnet housing is the stressed maximum housing part of transmission assembly, most important to the specified input torque of raising gearbox.Existing company needs to design a high pulling torque gearbox, therefore needs to be optimized on existing rear cover structure rear cover structure intensity, to strengthen, to meet structure needs.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of aluminum alloy bonnet housing.Use finite Element Intensity Analysis method, reinforcement process is carried out to existing rear lid case body structure strength weak position, thus improves existing aluminum alloy rear cover structure intensity.
For achieving the above object, the technical solution adopted in the utility model is: comprise bonnet housing, is provided with a circle for improving the perpendicular muscle of case of transmission and bonnet housing connection reliability at the link bolt hole place of bonnet housing and case of transmission; The first ring muscle for improving intermediate shaft hole place intensity and the second ring muscle is respectively arranged with in the outside at bonnet housing two intermediate shaft hole place; Surface, rear lid case inside and outside is provided with the stiffening rib for improving bonnet housing integral rigidity.
The position of described bonnet housing bolt connecting hole and intermediate shaft hole is consistent with case of transmission.
The overall wall thickness of described bonnet housing and the wall thickness of structure shape transition region are 4 ~ 6mm.
Described perpendicular muscle is evenly distributed on the both sides of connecting bolt, and the muscle of perpendicular muscle is thick consistent with the integral thickness of bonnet housing.
Described stiffening rib is distributed in around bonnet odd-side spindle hole of main and odd-side intermediate shaft hole radially.
The axis of described stiffening rib is by the center of bolt hole.
Described first ring muscle and the second ring muscle concentric with bonnet odd-side intermediate shaft hole, and tangent with bonnet hull outside.
Compared with prior art, the utility model has following beneficial effect:
The utility model, under the prerequisite not changing other parts of odd-side assembly, is optimized structural strength by reinforcement mode, improves the moment of torsion standby amount of bonnet casing rigidity and transmission assembly.Meanwhile, the utility model is after the perpendicular muscle of increase and ring muscle, and make surface structure compacter and attractive in appearance, Safety performance is better.The utility model can make 12 grades of aluminum alloy rear cover structure strength characters promote 30%, and meet transmission assembly performance requirement, in addition, it has no effect to other design of part of gearbox, cost-saving.Finally, the utility model is easy to manufacture, and product interchangeability is fine, and installation and maintenance are convenient.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein: 1 is first ring muscle; 2 is the second ring muscle; 3 is perpendicular muscle; 4 is clutch housing; 5 is case of transmission; 6 is bonnet housing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1, the utility model comprises bonnet housing 6, is provided with a circle for improving the perpendicular muscle 3 of case of transmission 5 and bonnet housing 6 connection reliability at bonnet housing 6 and the link bolt hole place of case of transmission 5; Perpendicular muscle 3 is evenly distributed on the both sides of connecting bolt, and the muscle of perpendicular muscle 3 is thick consistent with the integral thickness of bonnet housing 6.Be respectively arranged with the first ring muscle 1 for improving intermediate shaft hole place intensity and the second ring muscle 2 in the outside at bonnet housing 6 liang of intermediate shaft hole places, first ring muscle 1 and the second ring muscle 2 concentric with bonnet odd-side intermediate shaft hole, and tangent with bonnet hull outside.Bonnet housing 6 inner and outer surface is provided with the stiffening rib for improving bonnet housing integral rigidity, and stiffening rib is distributed in around bonnet odd-side spindle hole of main and odd-side intermediate shaft hole radially.The axis of stiffening rib is by the center of bolt hole.The position of bonnet housing 6 bolt connecting hole and intermediate shaft hole is consistent with case of transmission 5.The overall wall thickness of bonnet housing 6 and the wall thickness of structure shape transition region are 4 ~ 6mm.
Principle of the present utility model:
The utility model is ensureing under original aluminum alloy bonnet and transmission case Conncetion cimension and the constant prerequisite of fitted position, to the layout of thickness of shell, surperficial muscle, highly, thickness redesign.For meeting extrusion process requirement, by housing wall thickness and muscle thick thinning, improve the situation of the thicker bonnet compactness difference caused of original structure wall thickness.Ensure during design that the overall wall thickness of housing is consistent, change original structure wall thickness is inconsistent causes the phenomenon occurring shrinkage cavity during die casting as far as possible.Gap between stiffening rib is readjusted, avoids dark and little gap to produce, be conducive to die sinking, reduce die casting reject rate.
By transmission assembly structural stress analysis, finite Element Intensity Analysis, three times of quiet torsional test checkings, known speed changer is when odd-side drag-down transmitting torque, and input torque, after main tank and odd-side two-stage amplify, finally acts on bonnet intermediate shaft hole place.Whole case of transmission, bonnet housing two intermediate shaft hole place is stressed maximum.In actual using process, bonnet initial crack mostly occurs at intermediate shaft hole place, when improving rear lid case body structure, by increasing enhancing steel ring 1, the ring muscle 2 at two intermediate shaft hole places, improves intermediate bearing place intensity.Simultaneously in order to strengthen bonnet housing integral rigidity and improve die casting quality, take the arrangement of Bao Ergao to rearrange to rear cap surface muscle and due to bolt hole place stressed larger, so make stiffening rib axis pass through bolt hole center as far as possible, increase the perpendicular muscle 3 near housing and transmission case link bolt hole simultaneously, improve intensity and the bonnet integral rigidity at bolt hole place.
Above content is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technological scheme basis is done, within the protection domain all falling into the utility model claims.
