Abstract
A kind of high-strength light braking bottom board, relate to a kind of auto parts machinery, comprise braking bottom board body, the middle part of braking bottom board is a large center hole, top is provided with two supporting shaft hole, bottom is provided with a camshaft hole, it is characterized in that: between described two supporting shaft hole, be provided with a stiffening rib, supporting shaft hole upper end portion is that circular arc transition connects, a step type ABS hole is provided with in region between described center hole and two supporting shaft hole, between described camshaft hole and center hole, front is provided with three reinforcement convex tendons, strengthen both sides and the centre that convex tendon lays respectively at camshaft hole and center hole connection part for described three, the reverse side of this connection part is provided with two and strengthens gusset, the outer edge of braking bottom board reverse side is provided with two circular arc stiffening ribs.Advantage is: set up many stiffening ribs, not only added intensity, alleviated weight, reduce loose, cave in, the much casting defect such as thermal center, quality of product significantly improves, and the utility model is mainly used in automotive axle.
Description
Technical field
The utility model relates to a kind of auto parts machinery, is specifically related to the braking bottom board that a kind of vehicle bridge uses.
Background technique
The lighting of automobile component, high strength are the targets that people constantly pursue always, because this both can reduce tare, reduce manufacture cost, and reduce oil consumption, can also overloading goods, raising Safety performance.Braking bottom board is a kind of accessory be welded in vehicle bridge, majority is cast member, the middle part of braking bottom board is a large center hole, for being weldingly fixed on axletree, top is provided with two supporting shaft hole, hole wall is thick is generally 14-15mm, for installing back shaft, back shaft is the support turning point of brake shoe, brake shoe bottom is provided with a camshaft hole, for installing camshaft, braking bottom board is used for the associated components of fixed car braking device, comprise brake shoe, camshaft etc., the braking bottom board of prior art is due to more thick and heavy, some positions intensity is superfluous, some positions strength deficiency, place is linked as camshaft hole and center hole, great torsion can be subject to during brake, because of this position strength deficiency, often phenomenon of rupture is there is during use, in a word, existing braking bottom board not only product is thick and heavy, structure imperfection, thermal center is had to concentrate during casting, the unsuitable feeding in thermal center position etc., the subsurface defects such as easy generation shrinkage porosite, some defects being difficult to overcome such as easily ftracture when there is use.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of rational in infrastructure, is beneficial to casting, the braking bottom board that lightweight, intensity is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-strength light braking bottom board, comprise braking bottom board body, the middle part of braking bottom board is a large center hole, top is provided with two supporting shaft hole, bottom is provided with a camshaft hole, it is characterized in that: between described two supporting shaft hole, be provided with a stiffening rib, supporting shaft hole upper end portion is that circular arc transition connects, be conducive to casting and weight reduction, a step type ABS hole is provided with in region between described center hole and two supporting shaft hole, both can be used for ABS is installed, also the feeding of casting is conducive to, between described camshaft hole and center hole, front is provided with three reinforcement convex tendons, strengthen both sides and the centre that convex tendon lays respectively at camshaft hole and center hole connection part for described three, the reverse side of this connection part is provided with two and strengthens gusset, the outer edge of braking bottom board reverse side is provided with two circular arc stiffening ribs.
Further improvement of the present invention, the hole wall of described camshaft hole is columnar structured and assemblying body that is frustoconic shape structure, can ensure the intensity at this position, again can weight reduction.
A step more of the present invention is improved, the pore wall thickness of described supporting shaft hole is 10 ~ 12mm, because load is herein pressure, the too large function of wall thickness is superfluous, and easily there are the easy shrinkage porosite of thermal center and hole sunken inside etc. during casting, obviously can reduce in thermal center and hole the problem often occurring caving in after changing 10 ~ 12mm into, also mitigate weight.
Compared with prior art, advantage is in the present invention: set up many stiffening ribs, not only added intensity, alleviated weight, also greatly reduce loose, cave in, the much casting defect such as thermal center, quality of product is significantly improved.Also save material resources simultaneously, reduce manufacture cost.The intensity that a stiffening rib not only adds braking bottom board is provided with between two supporting shaft hole, the flowing of molten steel when being simultaneously also conducive to casting, a step type ABS hole is provided with in region between described center hole and two supporting shaft hole, be conducive to the feeding of thermal center position, the defect of large face casting can be eliminated, improve castability, the concaveconvex structure of step hole also can be gained in strength simultaneously, and the utility model is mainly used in automotive axle.

Embodiment
As Figure 1-3, high-strength light braking bottom board of the present utility model, comprise braking bottom board body, the middle part of braking bottom board is a large center hole 4, for being enclosed within welding location in vehicle bridge, top is provided with two supporting shaft hole 7, bottom is provided with a camshaft hole 1, a stiffening rib 8 is provided with between described two supporting shaft hole 7, supporting shaft hole 7 upper end portion is that circular arc transition 9 connects, a step type ABS hole 5 is provided with in region 6 between described center hole 4 and two supporting shaft hole 7, this district is casting region, large face, set up a step hole, be conducive to feeding when casting, between described camshaft hole 1 and center hole 4, front is provided with three reinforcement convex tendons 2, 3, strengthen convex tendon 2 for described three, 3 centre and the both sides laying respectively at camshaft hole and center hole connection part, the reverse side of this connection part is provided with two and strengthens gusset 12, the outer edge of braking bottom board reverse side is provided with two circular arc stiffening ribs 11, the hole wall of described camshaft hole 1 is columnar structured and assemblying body that is frustoconic shape structure 10, the pore wall thickness of described supporting shaft hole 7 is 10 ~ 12mm.
As shown in Figure 4, alternatively, above-mentioned step type ABS hole 5 also can central position between centre hole and two supporting shaft hole in region, is more conducive to the feeding of thermal center position, eliminates the defect of large face casting.
