Abstract
The invention relates to a differential speed variator for an automobile. The differential speed variator for the automobile comprises a box cover, a box body and a transmission mechanism. A power input hole and a power output hole are formed in the box cover, an annular boss and an annular rib are arranged with the power input hole as the center of a circle, and the diameter of the annular boss is smaller than that of the annular rib. Strip-shaped ribs which are distributed in a divergent shape are further arranged with the power output hole serving as the center of a circle. The inner side end of each strip-shaped rib is connected to the first annular boss. The outer side ends of part of strip-shaped ribs stretch out of the annular rib, and the outer side ends of the rest strip-shaped ribs are connected with a positioning column arranged on the annular rib. The number of the strip-shaped ribs at one side close to the power input hole is larger than that of the strip-shaped ribs at one side far away from the power input hole. The parts, located between the annular rib and the annular boss, of the strip-shaped ribs are coplanar with the annular rib and the annular boss. The depths of the parts, located outside the annular rib, of the strip-shaped ribs are decreased gradually until the parts are flushed with the box cover. The intensity of the power input hole and the power outlet hole of the box cover are increased, and the box cover can bear a comparatively large torque when the differential speed variator for the automobile works.
Description
Technical field
The present invention relates to automobile technical field, be specifically related to a kind of automobile-used differential speed variator.
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 automobile-used differential speed variator 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: a kind of automobile-used differential speed variator, comprise the shell be bolted by case lid and casing, and be arranged on the driving mechanism of enclosure, described case lid and casing are aluminum casting part, case lid is provided with power input hole and Power output hole, it is characterized in that: with described Power output hole for the center of circle be provided with one annular boss with together with annular muscle, described annular boss is looped around periphery, Power output hole, the diameter of annular muscle is greater than the diameter of annular boss, the bar shaped muscle of the distribution in divergent shape is also provided with centered by Power output hole, the medial extremity of every root bar shaped muscle is connected on 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 annular boss and annular muscle, annular boss is coplanar, the segment thickness be positioned at outside annular muscle reduces gradually, until flush with case lid.
As the further improvement of this programme, described power input hole periphery is provided with four circumferentially uniform location and installation boss, one of them location and installation boss is between power input hole and Power output hole, and be connected with power input hole by three connecting tendons, its excess-three location and installation boss is connected with power input hole respectively by each self-corresponding connecting plate, and connecting tendon and connecting plate coplanar.The moment of torsion born due to the lid section between power input hole and Power output hole is maximum, when therefore designing, is connected by the location and installation boss of this part by connecting tendon with power input hole.
Beneficial effect of the present invention: when automobile-used differential speed variator work, 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 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.
