Abstract
The utility model discloses a wheel hub bearing assembly for sandy beach car, its technical scheme main points are, including flange outer lane, flange inner circle, the flange outer lane with the flange inner circle forms by aluminium die -casting, the flange outer lane comprises with the outward flange dish the outer axle sleeve of an organic whole, the flange inner circle comprises with inner flange plate the interior axle sleeve of an organic whole, interior axle sleeve inserts to the outer axle sleeve in and coaxial setting, the cover is equipped with two ball bearing on the interior axle sleeve, make into to be formed by aluminium die -casting in the flange outer lane and flange inner circle of being made by the iron castings that will be original, the aluminium material has that density is low, corrosion resistant characteristics, have a corrosion resistance in that sandy beach car wheel hub's hookup location is whole like this, are difficult to appear the rusty condition.
Description
Technical field
The utility model relates to a kind of bearing structure, and more particularly, it relates to a kind of hub bearing assembly for beach buggy.
Background technique
Beach buggy is used on sandy beach, for people's recreational walking, and a kind of mode of people's first-selection.Residing for beach buggy, environment is seashore, and the Mare Humorum wind that throughout the year makes moist corrodes, and very easily gets rusty and cause bearing failure and axle precise decreasing between inner ring and axle.Again because the hub bearing outer ring etc. on beach buggy all utilizes Cast Iron Production to manufacture, cast iron gets rusty easily especially, and the heavier-weight of entirety, can cause certain burden to causing the operation of beach buggy.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of lighter weight, the erosion-resisting hub bearing assembly for beach buggy.
For achieving the above object, the utility model provides following technological scheme: a kind of hub bearing assembly for beach buggy, comprise flange outer ring, flange inner ring, described flange outer ring and described flange inner ring form by aluminium die casting, described flange outer ring is made up of external axle sleeve integrally and outward flange dish, described flange inner ring is made up of internal axle sleeve and the inner flange of one, and it is interior and coaxially arrange that described internal axle sleeve is inserted into external axle sleeve, described internal axle sleeve is arranged with two ball bearings.
The utility model is set to further: described inner flange and beach buggy brake disc are connected by screw, and described outward flange dish and sand bank vehicle wheel hub are connected by screw.
The utility model is set to further: described external axle sleeve is provided with the convenient depressed part gripped, and depressed part quantity is that two axis about external axle sleeve are symmetrical set.
Compared with prior art, the utility model has the advantage of, by original flange outer ring of being made up of iron castings and flange inner ring, make into by aluminium die casting, aluminium material has low, the corrosion resistant feature of density, in the link position entirety of sand bank vehicle wheel hub, there is corrosion resistance like this, be not easy the situation occurring getting rusty.And when structural strength, total quality is lower, two bearings between exterior and interior axle sleeves can guarantee the structural stability of joint, meet the stable connection of beach buggy wheel.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model for the hub bearing assembly embodiment of beach buggy;
Fig. 2 is the plan view of the utility model for the hub bearing assembly embodiment of beach buggy.
Reference character: 11, external axle sleeve; 111, depressed part; 12, outward flange dish; 21, internal axle sleeve; 22, inner flange; 3, ball bearing.
Embodiment
Referring to figs. 1 through Fig. 2, the hub bearing assembly embodiment that the utility model is used for beach buggy is described further.
A kind of hub bearing assembly for beach buggy, comprise flange outer ring, flange inner ring, described flange outer ring is made up of with outward flange dish 12 external axle sleeve 11 of one, and described flange inner ring is made up of with inner flange 22 internal axle sleeve 21 of one, and described internal axle sleeve 21 is inserted in external axle sleeve 11.The external diameter of internal axle sleeve 21 is 30mm, and the internal diameter of external axle sleeve 11 is 56mm, and the shape of outward flange dish 12 is square, and be provided with four screw holes above, outward flange dish 12 is fixedly connected with by screw with the wheel hub of beach buggy, and outward flange dish 12 is connected with wheel hub.The shape of inner flange 22 is circular, and be also provided with 4 screw holes above, inner flange 22 is connected with the brake disc of beach buggy by screw hole.
Wherein, flange outer ring and flange inner ring form by aluminium die casting, by original flange outer ring of being made up of iron castings and flange inner ring, make into by aluminium die casting, aluminium material has low, the corrosion resistant feature of density, in the link position entirety of sand bank vehicle wheel hub, there is corrosion resistance like this, be not easy the situation occurring getting rusty.
External axle sleeve 11 is provided with the convenient depressed part 111 gripped, and depressed part 111 quantity is that two axis about external axle sleeve 11 are symmetrical set, and depressed part 111 can be convenient for people to conveniently hold when this assembly of crawl.
Internal axle sleeve 21 is consistent with the length of external axle sleeve 11, and when plugging together, both just in time overlap completely on frontal plane of projection.Described internal axle sleeve 21 is arranged with two ball bearings 3, described ball bearing 3 inner ring and internal axle sleeve 21 outer wall fit tightly, and the outer ring of described ball bearing 3 and the inwall of described external axle sleeve 11 fit tightly, and described ball bearing 3 quantity is two.As shown in Figure 1, two ball bearings 3 lay respectively at the end of external axle sleeve 11 inwall, the end of internal axle sleeve 21 outer wall.By the ball bearing of two on axle sleeve 3, play the effect strengthening integrated support structure intensity, can guarantee that beach buggy roller remains steady state in operation process, and ball bearing 3 is positioned at the two ends of internal axle sleeve 21 and external axle sleeve 11, so just guarantee stressed reasonable dispersion, both sides are stressed emphasis, and sharing of such strength is just comparatively easy.
Wherein, external axle sleeve 11 inwall is provided with and is integrally formed with bulge loop, and conflict with two ball bearing 3 outer rings respectively in described bulge loop both sides, described internal axle sleeve 21 is arranged with spacer, conflicts respectively at two ball bearing 3 inner rings in described spacer both sides.Position and the described bulge loop of described spacer are just right, and described bulge loop is consistent with the axial length of described spacer.
Coordinate the bulge loop on Upper shaft sleeve and spacer, can guarantee that the position of ball bearing 3 can install more for convenience, directly bearing is inserted in and just can, play the effect of a location, can not allow the dislocation that bearing is being installed, and be clipped in and make two bearings be not easy to occur loosening in working procedure in the middle of two ball bearings 3.
Wherein, described ball bearing 3 is stuffing box bearing, and roller bearing both sides are equipped with the oil sealing for sealing.Stuffing box bearing is comparatively common on the market, after once adding grease injection, long steady running may be kept, the oil sealing of both sides plays effect that is dust-proof, that prevent grease from overflowing, this bearing integral is stronger, not high to whole hub bearing assembly structural requirement, remove and install more for convenience.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
