Abstract
The invention relates to a high-torque differential gearbox shell. The high-torque differential gearbox shell comprises a box cover and a box body. A power input hole and a power output hole are formed in the box cover. A first annular boss, an annular rib and strip ribs which are distributed in a scattered mode are arranged by using the power output hole as the circle center. The inner side end of each strip rib is connected with the first annular boss. The outer side ends of some strip ribs extend out of the annular rib, and the outer side ends of the other strip ribs are connected with positioning columns arranged on the annular rib. The number of the strip ribs which are close to the power input hole is large than the number of the strip ribs which are far away from the power input hole. The parts, between the annular rib and the first annular boss, of the strip ribs are in the same plane with the parts of the annular ribs and the first annular boss. The thickness of the parts, outside the annular rib, of the strip ribs is gradually decreased. A second annular boss is arranged around of the power input hole, and the first annular boss is connected with the second annular boss through a third annular boss. The intensity between the power output hole and the power input hole which are formed in the box cover is enhanced, and the box cover can bear the big torque when a vehicle differential gearbox is in use.
Description
Technical field
The present invention relates to automobile technical field, be specifically related to the differential gear box casing of a kind of high moment of torsion.
Background technique
Difference speed changer carries out the closed knockdown variable speed drive of one by basic model speed changer to differential gear train, by transmission parameter variant in selecting device, realize accurate speed governing and expand the bearing capacity of basic model speed changer, or expanding the speed adjustable range of basic model speed changer.
The differential gearbox used in current automobile industry, as shown in Figure 2, usually by shell, and the driving mechanism C being arranged on enclosure forms.Shell is made up of case lid B and casing A, and both are cast member, and case lid B is provided with power input hole 1 and Power output hole 2.When automobile differential transmitter works, casing A and case lid B can bear larger moment of torsion, but because power input, output are all in case lid B side, therefore higher to the requirement of strength of case lid B, usually stiffening rib can be set on case lid B to improve bulk strength.But for the poor speed changing assembly that some outputting power requires, existing stiffening rib cannot meet requirement of strength.
Summary of the invention
The present invention aims to provide a kind of automobile-used differential speed variator that can bear compared with high pulling torque, improves its case lid intensity, to ensure that case lid still can ensure good usability when bearing larger moment of torsion.
For this reason, the technical solution adopted in the present invention is: the differential gear box casing of a kind of high moment of torsion, comprise case lid and casing, both are aluminum casting part, snap together and locked by bolt and nut component, it is characterized in that: with described Power output hole for the center of circle be provided with together the first annular boss with together with annular muscle, described first annular boss is looped around periphery, Power output hole, the diameter of annular muscle is greater than the diameter of the first annular boss, with Power output hole for the center of circle is also provided with the bar shaped muscle distributed in divergent shape, the medial extremity of every root bar shaped muscle is connected on the first annular boss, the outboard end of part bar shaped muscle extends to outside annular muscle, the outboard end of part bar shaped muscle is connected with the locating column that annular muscle is arranged, and the bar shaped muscle near power input hole side is more than the bar shaped muscle away from power input hole side, the part of described bar shaped muscle between annular muscle and the first annular boss and annular muscle, first annular boss is coplanar, the segment thickness be positioned at outside annular muscle reduces gradually, until flush with case lid,
Described power input hole periphery is provided with the second annular boss, and the first annular boss is connected by the 3rd annular boss with the second annular boss, four circumferentially uniform location and installation boss are provided with in the periphery of the second annular boss, one of them location and installation boss is between power input hole and Power output hole, and be connected with the second annular boss by three connecting tendons, its excess-three location and installation boss is connected with the second annular boss respectively by each self-corresponding connecting plate, the width of described connecting plate, article three, the overall width of connecting tendon is reduced to each self-corresponding location and installation boss gradually by the second annular boss.
Beneficial effect of the present invention: when differential speed variator works, lid section between power input hole and Power output hole can bear larger moment of torsion, and the present invention arranges the combination stiffening rib be made up of bar shaped muscle and annular muscle between power input hole and Power output hole, and the bar shaped muscle limited near power input hole side is more than the bar shaped muscle away from power input hole side, to enhance the intensity of case lid intermediate portion, guaranteeing that case lid can bear more while high pulling torque, save material to greatest extent, reduce cost; Meanwhile, by limiting the thickness of bar shaped muscle, make perfect transition between bar shaped muscle and the first annular boss, annular muscle, case lid outer surface, entirety is more coordinated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the internal structure schematic diagram of existing automobile-used differential speed variator.
