Abstract
A kind of high-strength light back-plate, it is a big centre bore to be related in the middle part of a kind of auto parts machinery, including back-plate body, back-plate, and top is provided with two supporting shaft hole, and bottom is provided with a camshaft hole, it is characterised in that：Provided with a reinforcement between described two supporting shaft hole, supporting shaft hole upper end connects for circular arc transition, provided with a step ABS hole in region between the centre bore and two supporting shaft hole, front is provided with three reinforcement convex tendons between the camshaft hole and centre bore, described three are strengthened the both sides and centre that convex tendon branch is located at camshaft hole and centre bore connecting portion, and the reverse side of the connecting portion is provided with two stiffener plates；The outer edge of back-plate reverse side is provided with two circular arc reinforcements.Advantage is：Be additionally arranged a plurality of reinforcement, not only add intensity, alleviate weight, reduce it is loose, cave in, many casting flaws such as thermal center, product quality significantly improves, and present invention is mainly applied to automotive axle.
Description
Technical field
The present invention relates to a kind of auto parts machinery, and in particular to the back-plate used in a kind of vehicle bridge.
Background technology
The lighting of automobile component, high intensity are always the target that people constantly pursue, because this can both reduce vehicle body
Weight, reduces manufacturing cost, reduces oil consumption, can also many loadings, raising security performance.Back-plate is welded in vehicle bridge
A kind of accessory, majority is cast member, is a big centre bore in the middle part of back-plate, for being weldingly fixed on axletree, on
Side is usually 14-15mm provided with two supporting shaft hole, hole wall thickness, and for installing support shaft, support shaft is the support rotation of brake-shoe
Turning point, brake-shoe bottom is provided with a camshaft hole, and for installing camshaft, back-plate is used for fixed car brake apparatus
Associated components, including brake-shoe, camshaft etc., the back-plate of prior art is thick and heavy due to comparing, and some position intensity is superfluous,
Some position intensity is not enough, and the place that links of such as camshaft hole and centre bore can be by great torsion, because the position is strong during brake
Degree is not enough, often occurs phenomenon of rupture when using, in a word, not only product is thick and heavy for existing back-plate, structure imperfection, during casting
There is a thermal center concentration, unsuitable feeding in thermal center position etc. is also easy to produce the internal flaws such as shrinkage porosite, exist and easily ftracture etc. some when using
It is difficult to the defect overcome.
The content of the invention
The problem to be solved in the present invention be to provide it is a kind of rational in infrastructure, beneficial to casting, the high braking bottom of lightweight, intensity
Plate.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of high-strength light back-plate, including
It is a big centre bore in the middle part of back-plate body, back-plate, top is provided with one provided with two supporting shaft hole, bottom
Camshaft hole, it is characterised in that：Provided with a reinforcement between described two supporting shaft hole, supporting shaft hole upper end is circular arc
Transition is connected, and is conducive to casting and mitigating in weight, the region between the centre bore and two supporting shaft hole provided with a platform
Stepwise ABS holes, can be not only used for installing ABS, are also beneficial to the feeding of casting, front is provided between the camshaft hole and centre bore
Three reinforcement convex tendons, described three are strengthened the both sides and centre that convex tendon branch is located at camshaft hole and centre bore connecting portion, should
The reverse side of connecting portion is provided with two stiffener plates；The outer edge of back-plate reverse side is provided with two circular arc reinforcements.
Further improvement of the present invention, the hole wall of the camshaft hole is the columnar structured combination with truncated cone-shaped structure
Body, both can guarantee that the intensity at the position, can mitigate weight again.
Another step of the present invention is improved, and the pore wall thickness of the supporting shaft hole is 10 ~ 12mm, because load herein is pressure
Power, wall thickness too big function is superfluous, and easily the easy shrinkage porosite of thermal center and hole sunken inside etc. occurs during casting, and being changed to after 10 ~ 12mm can be with
The problem of being often recessed in thermal center and hole is significantly reduced, weight is also mitigated.
Compared with prior art, advantage is the present invention：A plurality of reinforcement is additionally arranged, intensity is not only added, weight is alleviated
Amount, be also greatly reduced it is loose, cave in, many casting flaws such as thermal center, significantly improve product quality.Also save material simultaneously
Expect resource, reduce manufacturing cost.The intensity of back-plate is not only added between two supporting shaft hole provided with a reinforcement,
It is also beneficial to simultaneously in the flowing of molten steel during casting, the region between the centre bore and two supporting shaft hole provided with a step
Formula ABS holes, are conducive to the feeding of thermal center position, can eliminate the defect of big face casting, improve casting character, while stepped hole is recessed
Male structure can also increase intensity, and present invention is mainly applied to automotive axle.
Brief description of the drawings
Fig. 1 is the positive structure schematic of high-strength light back-plate.
Fig. 2 be in Fig. 1 A-A to sectional view.
Fig. 3 is the structural representation of high-strength light back-plate reverse side.
Fig. 4 is the structural representation of another embodiment of high-strength light back-plate.
Embodiment
As Figure 1-3, high-strength light back-plate of the invention, including back-plate body, the middle part of back-plate
It is centre bore 4 one big, positioning is welded for being enclosed in vehicle bridge, top is provided with two supporting shaft hole 7, and bottom is convex provided with one
Provided with a reinforcement 8 between axle hole 1, described two supporting shaft hole 7, the upper end of supporting shaft hole 7 is that circular arc transition 9 connects
Connect, provided with a step ABS hole 5 in the region 6 between the centre bore 4 and two supporting shaft hole 7, the area casts for big face
Area, sets up a stepped hole, is conducive to feeding during casting, and front adds provided with three between the camshaft hole 1 and centre bore 4
Strong convex tendon 2,3, strengthens convex tendon 2,3 branches for described three and is located at the centre and both sides of camshaft hole and centre bore connecting portion, should
The reverse side of connecting portion is provided with two stiffener plates 12；The outer edge of back-plate reverse side is provided with two circular arc reinforcements 11；Institute
State assembly of the hole wall of camshaft hole 1 for columnar structured and truncated cone-shaped structure 10；The pore wall thickness of the supporting shaft hole 7 is
10~12mm。
As shown in figure 4, alternatively, above-mentioned step ABS holes 5 can also centre hole and two branch
Center between support axis hole in region, is more beneficial for the feeding of thermal center position, eliminates the defect of big face casting.
