Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of case lid of automobile differential transmitter assembly.
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 differential transmitter assembly 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.
Model utility content
The utility model aims to provide a kind of case lid that can bear automobile differential transmitter assembly compared with high pulling torque, improves the intensity of case lid, to ensure that case lid still can ensure good usability when bearing larger moment of torsion.
For this reason, the technological scheme that the utility model adopts is: a kind of case lid of automobile differential transmitter assembly, described case lid is provided with power input hole and Power output hole, with 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, 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 annular boss, the outboard end of bar shaped muscle at least extends on annular muscle, and the bar shaped muscle near power input hole side is more than the bar shaped muscle away from power input hole side.
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.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.
The beneficial effects of the utility model: when automobile differential transmitter assembly works, part between the power input hole of case lid and Power output hole can bear larger moment of torsion, and case lid 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the internal structure schematic diagram of existing automobile differential transmitter assembly.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
The case lid of automobile differential transmitter assembly as shown in Figure 1, case lid is provided with power input hole 1 and Power output hole 2, and power input hole 1 is for installing power input shaft, and Power output hole 2 is for installing pto＝power take-off.
With Power output hole 2 for the center of circle be provided with one annular boss 3 with together with annular muscle 4, annular boss 3 is looped around periphery, Power output hole 2, and the diameter of annular muscle 4 is greater than the diameter of annular boss 3.Be the bar shaped muscle 5 that the center of circle to be also provided with in divergent shape distribution with Power output hole 2, the medial extremity of every root bar shaped muscle 5 is connected on annular boss 3, and the outboard end of bar shaped muscle 5 at least extends on annular muscle 4, and part bar shaped muscle 5 outboard end reaches outside annular muscle 4.
In order to increase the intensity on case lid between power input hole 1 and Power output hole 2, bar shaped muscle 5 near power input hole 1 side is more than the bar shaped muscle 5 away from power input hole 1 side, namely the bar shaped muscle 5 between power input hole 1 and Power output hole 2 is closeer, and the bar shaped muscle 5 away from power input hole 1 side is relatively sparse.
Preferably, power input hole 1 periphery is provided with four circumferentially uniform location and installation boss 6, one of them location and installation boss 6 is between power input hole 1 and Power output hole 2, and be connected with power input hole 1 by three connecting tendons 7, its excess-three location and installation boss 6 is connected with power input hole 1 respectively by each self-corresponding connecting plate 8.
