Abstract
The utility model relates to a part for an automobile, in particular to a flange plate for an automobile hub hearing unit. The flange plate for the automobile hub bearing units mainly solves the technical problems that in the prior art, the contact area between a steel ball of a hub unit and the inner surface of a flange plate is larger, so that the abrasion of the steel ball to a channel is larger and the rolling of the steel ball is unsmooth, and the like. The flange plate for the automobile hub bearing unit comprises the flange plate (1) and is characterized in that a through hole (2) connected with a rotating shaft in a penetrating way is arranged inside the flange plate (1), a dual-channel (3) which can be used for installing the steel ball is arranged on the inner surface of the through hole, and arc grooves (4) are arranged at two outer sides of the dual-channel (3) respectively.
Description
Technical field
The utility model relates to a kind of component of automobile, especially relates to a kind of automobile hub bearing flange plate.
Background technique
Along with the development of technology, the level of integration of automobile hub bearing is increasingly high.Automobile has generally comprised inner ring, outer ring with bearing unit, is fixed with single-row through retainer or the biserial roller between the Internal and external cycle.Chinese patent discloses a kind of hub-bearing unit, and (notice of authorization number: CN201671960U), it comprises flange plate, inner ring, outer ring, ball, interior retainer, outer retainer, and inner ring is installed in the end of flange plate outside; Said outer ring is installed in the root of flange plate outside; Be provided with first raceway groove and second raceway groove of ring-type between outer ring and flange plate and the inner ring, first raceway groove is one side in the flange plate end, and second raceway groove is in flange plate root one side; In first raceway groove and second raceway groove, be provided with ball; Roll through described two row's balls with flange plate and inner ring and be connected in the outer ring, interior retainer is installed in first raceway groove, and outer retainer is installed in second raceway groove; The diameter of second raceway groove is greater than the diameter of said first raceway groove, and the ball in second raceway groove is more than the ball in first raceway groove; The flange plate end is provided with the crimping with the flange plate one, and crimping is close to an end of said inner ring; 18 balls are housed in first raceway groove, 20 balls are housed in second raceway groove; Inner ring also is provided with speed sensor outward, and speed sensor comprises magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automobile hub bearing (notice of authorization number: CN201401445); It comprises flange plate inner ring, flange plate outer ring, inside race, ball and retainer; The flange plate outer ring internal surface is provided with two outer raceways, respectively be provided with on flange plate inner ring and the inside race outer surface and the corresponding interior raceway of outer raceway, ball be placed in the retainer inscribe interior raceway and outside between the raceway; Have annular groove and step surface on the flange plate inner ring outer surface; Be provided with annular retaining ring in the groove, inside race one end face is resisted against on the annular retaining ring, and the other end is resisted against on the step surface.But the area of contact of the steel ball of these two kinds of hubs and flange plate internal surface is bigger, and steel ball is bigger to the wearing and tearing of raceway groove on the one hand, and the rolling of steel ball has some setbacks on the other hand.
The model utility content
The utility model provides a kind of automobile hub bearing flange plate; It mainly is that to solve the area of contact of steel ball and flange plate internal surface of existing in prior technology hub bigger; On the one hand steel ball is bigger to the wearing and tearing of raceway groove, on the other hand the technical problem that has some setbacks etc. of the rolling of steel ball.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The automobile hub bearing flange plate of the utility model comprises flange plate, but described flange plate inside is provided with the through hole of cross-under rotating shaft, and the internal surface of through hole is provided with the double channel that steel ball can be installed, and two outsides of double channel all have arc groove.In the through hole of flange plate, inner ring can be installed, directly offer double channel at the flange plate internal surface, make its setting of having cancelled the outer ring, processing is comparatively simple like this, and cost of production is less.Between flange plate and the inner ring steel ball can be installed.Offer arc groove, can prevent the worn steel ball double channel on the one hand, keep the running of steel ball.Can in arc groove, be marked with grease on the other hand, improve the service requirement of hub.
As preferably, the through-hole inner surface of described double channel one end has draw-in groove.Can the clamping seal ring in the draw-in groove, hub can prevent that in use seal ring from coming off like this, makes that the working life of hub is longer.
As preferably, described draw-in groove is a circular arc, and its arc round angle is 45-60 °.The draw-in groove arc transition can be so that Sealing can more easily be connected to draw-in groove inside.
As preferably, the outer surface of described flange plate is provided with step.A plurality of steps are set, can be so that wheel hub be installed in the automobile.
Therefore, the utility model is offered arc groove at the double channel place of the inside of flange plate, can reduce the area of contact of steel ball and flange plate, and it is more smooth and easy, simple and reasonable for structure to make that steel ball rolls.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is A portion structure for amplifying schematic representation of Fig. 1.
Component, position and numbering among the figure: flange plate 1, through hole 2, double channel 3, arc groove 4, draw-in groove 5, step 6.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the automobile hub bearing flange plate that this is routine, like Fig. 1, a flange plate 1 is arranged, the outer surface of flange plate is provided with step 6.But flange plate inside is provided with the through hole 2 of cross-under rotating shaft, and the internal surface of through hole is provided with the double channel 3 that steel ball can be installed, and two outsides of double channel 3 all have arc groove 4.The through-hole inner surface of double channel one end has draw-in groove 5, and draw-in groove is a circular arc, and its arc round angle is 55 °.
During use, assemble inner ring, steel ball after, Sealing be pressed onto between inner ring and the flange plate end get final product.At last whole hub-bearing unit is packed into and can use in the automobile.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
