Abstract
A wheel hub unit ABS encoder comprises a framework and a magnet connected in one body; the magnet has an N pole and an S pole; a periphery of the framework is provided with fuse holes; the magnet tightly attaches on the framework; in a sulfuration or heat injection moulding step, part of the magnet material is fused and penetrates each corresponding fuse hole so as to be moulded by a die on the other end face of the framework, thus forming a fuse structure with a fuse piece, and the framework and the magnet are fixed in one body. Because the fuse piece and the fuse structure are formed, relative rotation between the framework and the magnet cannot happen and thus causing loosening and disengagement phenomenon, slits cannot be formed between the magnet and the framework, thereby providing a stable alternate magnetic field for the ABS encoder, and greatly improving ABS encoder work reliability, and preventing ABS system signal abnormity, deletion and failure phenomenon from happening.
Description
Technical field
The utility model relates to a kind of ABS scrambler, and a kind of being arranged on automotive hub particularly, with wheel and the synchronous hub ABS scrambler rotating of bearing.
Background technology
For reaching, guarantee that automobile, when having the shortest braking distance, also has good operability and maximum security, on existing automobile hub bearing, ABS scrambler is generally all installed.
Existing scrambler is many is circular O-ring seal skeleton and the integral body that is fixed into through the form of adhesive bond or bonding sulfuration, bonding injection moulding with the magnetizer of N, S polarity by surface.Scrambler is arranged on a side of hub and rotates with bearing inner race, for ABS system provides stable alternating magnetic field.After longevity of service, between skeleton and magnetizer, just there will be bonding become flexible or relatively rotate and break-off, make to produce gap between magnet part and skeleton, and then cause ABS system signal extremely even to lack, lost efficacy, reliability reduces and the safety traffic of vehicle is caused to great threat.
The patent No. 200720159560.7 " band rubber magnetic encoder ABS automobile hub bearing ", its O-ring seal skeleton of the scrambler providing is fixed as one with the magnetization rubber ring bonding with N, S polarity.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of hub ABS scrambler is provided, make to form between each parts of scrambler, connect firm, long-term use can not become flexible, rotation, break-off, has greatly improved the quality of ABS scrambler and the reliability of use.
The technical scheme in the invention for solving the above technical problem is: hub ABS scrambler, by skeleton, the integral body that connects into N, the magnet of S magnetic pole, formed, on the periphery of described skeleton, there is fusion hole, described magnet is close to skeleton and is installed, described magnet is in sulfuration or hot injection moulding process, the melting of magnet part material sees through the corresponding hole that respectively fuses and by mould shape, becomes the fusion structure with clinker in skeleton other end, and skeleton, magnet are fixed into integral body.
Compared with prior art, the utility model has the advantage of: the member skeleton of scrambler, magnet, the mode of the sulfuration of former utilization bonding, bonding injection moulding is fixed into integral body, after longevity of service, will occur becoming flexible because relatively rotating, break-off, make to produce gap between magnet part and skeleton, cause ABS system signal abnormal, even lack, lost efficacy.Now adopt by the part magnet material on magnet and after melting, through fusion hole, in skeleton other end, by mould shape, become the fusion structure with clinker in sulfuration or hot injection moulding process, skeleton, magnet are fixedly connected into integral body, it has been exactly longevity of service, because thering is clinker and fusion structure, between skeleton, magnet, can not relatively rotate and occur loosening, break-off between the two, guarantee that air-gap is therebetween constant, for ABS scrambler provides stable alternating magnetic field, also greatly improved the reliability of ABS scrambler work.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Skeleton 2,2 ', 2 " adopt metal material to make; outside surface is step ladder circular ring shape, have fusion hole uniform, that size is identical on the periphery of the large end of annular, fusion hole can be various difformities; as the caulking groove 4-3 of arc notch 4-1 or through hole 4-2 or various shapes etc., as shown in Fig. 3,4,5.
Magnet 1 is annular, by ferrite and NBR rubber mix or the composite material of ferrite and engineering plastics is made.
Magnet 1 is close to skeleton 2, in sulfuration or hot injection moulding process by the melting see through and correspondingly on skeleton 2 respectively to fuse in hole respectively of part magnet material, as arc notch 4-1, by sulfurizing mould or hot injection mold, shape and in the other end of skeleton, form the fusion structure with fusion piece 5, as shown in Fig. 1, Fig. 6.
Fusion piece 5 can be any needed shape according to mould, thereby magnet, skeleton are fixed into whole ABS scrambler 6, as shown in Figure 1.
Then on the outside surface of magnet, magnetize, on the inside and outside surface of magnet 1, form multipole right N, S magnetic pole 3, as shown in Figure 2.
During use, ABS scrambler 6 is arranged on hub 7, with bearing inner race, rotates, as shown in Figure 7.
