For the shortcoming and defect that prior art exists, the utility model provides a kind of hub bearing assembly.
The technological scheme that the utility model adopts is: a kind of hub bearing assembly, it comprises outward flange, sheathed half inner ring in outward flange, retainer passage is formed between half inner ring and outward flange, a pair retainer is provided with in described retainer passage, described retainer is provided with steel ball, in described half inner ring, sensor is set, described hub bearing assembly also comprises the magnetic gasket that seal ring and magnetic circle integrative-structure design, described magnetic gasket is between half inner ring and outward flange, and side and the sensor of described magnetic gasket are tangent.
The magnetic material of described magnetic gasket is for moulding magnetic.
The number of magnetic poles of described magnetic gasket is 88N/S.
The magnetic intensity of described magnetic gasket is that 30 millis are special.
Described magnetic gasket is fixed on outward flange, and is linked with outward flange.
Described sensor keeps relative consistent with the position of magnetic gasket.
Described magnetic gasket is fixed between outward flange and half inner ring by skeleton.
Described skeleton one end is fixed on the inwall of outward flange, and the other end is against on the outer wall of half inner ring by elastic foot.
The beneficial effects of the utility model are: the utility model has compact structure, lightweight, rigidity good, reliability is high, long service life, easy for installation, without the need to regulate bearing assemble play, disposable dress fat, the excellent properties such as freedom from repairs, the vehicle that the utility model can promote other series hub bearing simultaneously in any use two generation is applied, there is larger popularization space, good market prospects.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is the enlarged view at A place in Fig. 1.
Fig. 4 is the structural representation of skeleton.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model discloses a kind of hub bearing assembly, it comprises outward flange 1, sheathed half inner ring 2 in outward flange 1, retainer passage is formed between half inner ring 2 and outward flange 1, a pair retainer 46 is provided with in described retainer passage, described retainer 46 is provided with steel ball 4, in described half inner ring 2, sensor 15 is set, described hub bearing assembly also comprises the magnetic gasket 68 that seal ring and magnetic circle integrative-structure design, described magnetic gasket 68 is between half inner ring 2 and outward flange 1, side and the sensor 15 of described magnetic gasket 68 are tangent.
Described sensor 15 and half inner ring 2 interference fit, and sensor 15 is rectangular shape, its one end is fixed in half inner ring 2, and the other end is then arranged on the side of magnetic gasket 68, and therefore, the utility model changes the mode in the past adopting end face to magnetize into side and magnetizes.
The magnetic material of described magnetic gasket 68 is for moulding magnetic.Mould magnetic and magnetic plastics, magnetic plastics can be divided into structural type and compound two kinds by composition, and structural type magnetic plastics refers to that polymer itself has ferromagnetic magnet; Compound magnetic plastics refer to the magnet made with Magnaglo mixing bond processing for tackiness agent with plastics or rubber.The major advantage of magnetic plastics is: density is little, impact strength is large, can carry out cutting, cut, hole, weld, the processing such as lamination and embossing, can not be chipping during use, it can adopt the general processing method of general plastics (as injection, mold pressing, extruding) to process, can be processed into that dimensional accuracy is high, the goods of thin-walled, complicated shape, plastic band inserts goods, realize the miniaturization of electromagnetic equipment, lightweight, precise treatment and high performance.
Because two its inner spaces of generation hub-bearing unit are less, therefore can not adopt original rubber magnet, and use instead and mould magnetic, to meet the demand in its space.
The number of magnetic poles of described magnetic gasket 68 is 88N/S, and the magnetic intensity of described magnetic gasket 68 is that 30 millis are special.Parameter sets according to the demand of electronic control unit, to ensure the normal detection of sensor.
Described magnetic gasket 68 is fixed on outward flange 1, and is linked with outward flange 1, and outward flange 1 rotates, and half inner ring 2 maintains static, and namely sensor 15 is motionless, and magnetic seal 68 rotates, and realizes cutting magnetic field.
As shown in Figure 3 and Figure 4, described sensor 15 and the position of magnetic gasket 68 keep relative consistent, and described magnetic gasket 68 is fixed between outward flange 1 and half inner ring 2 by skeleton 3.Described skeleton 3 one end is fixed on the inwall of outward flange 1, and the other end is against on the outer wall of half inner ring 2 by elastic foot 31.By regulating the position of skeleton 3 to realize magnetic gasket 68 and the change in location of sensor 15, regulate its distance according to actual output voltage, to meet the different needs.
The utility model is exactly the interface sized fraction keeping bearing and automobile on the basis of second generation hub-bearing unit, a kind of novel second generation hub-bearing unit with anti-lock function formed in conjunction with abs sensor.Be fixed on by abs sensor on half inner ring 2, annular magnet seal ring 68 is fixed on outward flange 1.When outward flange 1 rotates, annular magnet seal ring 68 rotates thereupon, and abs sensor keeps fixing, can realize the measurement to information such as rotating speeds, then jointly form the ABS system of automobile with electronic control unit, brake-pressure controller.The technical order of its excellence is embodied in: ABS is used on car second generation hub-bearing unit, the electromagnetic induction voltage produced in vehicle wheel rotation process, pass through automatical control system, keep car brake to rolling while the sliding mode slided, prevent from skidding, play the effect of ABS anti-lock, improve the Security of car.
ABS anti-lock braking system should be inherited: 1 with the second generation hub-bearing unit of abs sensor, shorten stopping distance, 2, increase insensitivity, 3, reduce tire friction, 4, easy to use, the advantages such as reliable operation, the utility model has compact structure simultaneously, lightweight, rigidity is good, reliability is high, long service life, easy for installation, play is assembled without the need to regulating bearing, disposable dress fat, the excellent properties such as freedom from repairs, the vehicle that the utility model can promote other series hub bearing simultaneously in any use two generation is applied, there is larger popularization space, good market prospects.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
