Embodiment
Understood according to noted earlier, found after existing knuckle assembly is assembled on vehicle, when vehicle takes a sudden turn, turned
Noise can be produced to section assembly.
Found through initial analysis, the reason for knuckle assembly produces noise when causing the vehicle to take a sudden turn there may be a lot, example
Such as, the inner ring of hub bearing of interference fit and the flange shaft of radially inner side rotate against in the circumferential originally, spline connection
The exception of flange shaft and the drive shaft of radially inner side engages etc..Found through all reasons are carried out with investigation one by one, it is really former
Because being：When vehicle takes a sudden turn, knuckle assembly in the presence of the active force, can be interference fitted originally by an active force
The shell of knuckle and the outer ring of hub bearing can rotate against in the circumferential, thus produce noise.
In consideration of it, the invention provides a kind of improved knuckle assembly, its outer ring of hub bearing, knuckle it is outer
In shell, one of them is provided with protuberance, and another is provided with depressed part, and protruding parts are in depressed part, to realize outer ring and shell
Between anti-in hub bearing circumference rotate against cooperation, it is therefore prevented that the generation of noise.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
First embodiment
With reference to shown in Fig. 1 to Fig. 3, a kind of knuckle assembly is present embodiments provided, the knuckle assembly includes hub spindle
The shell 2 of 1 and knuckle is held, shell 2 is located at the radial outside of hub bearing 1.
In the present embodiment, the outer peripheral face of outer ring 10 is provided with protuberance 100, protuberance 100 from the periphery of outer ring 10 towards
Outer protrusion, the inner peripheral surface of shell 2 are provided with depressed part 20, and protuberance 100 is located in depressed part 20, to realize outer ring 10 and shell 2
Anti- in hub bearing circumference rotates against cooperation.In the inventive solutions, it is so-called anti-to rotate against cooperation and refer to
Shell 2 is fixed with outer ring 10 in the circumference of hub bearing 1, and both can not rotate against.So, when vehicle takes a sudden turn,
Under the mating reaction of protuberance 100 and depressed part 20, outer ring 10 can be prevented to be rotated against with shell 2, it is thus possible to from preventing
Produce noise.
In the inventive solutions, outer ring 10 can be interference fitted with shell 2, can also interference fits or gap match somebody with somebody
Close.
In the present embodiment, outer ring 10 and shell 2 are realized by way of key connection described anti-rotates against cooperation.Its
In, the outer peripheral face of outer ring 10 is provided with depressed part 101, and depressed part 101 is the first keyway, and protuberance 100 is to coordinate with depressed part 101
Key, and stretched out from depressed part 101, depressed part 20 is the second keyway being arranged on shell 2.
In a particular embodiment, the key on outer ring 10 is round end flat key.It should be noted that in technical scheme
In, do not have concrete restriction for the type of key, for example, the type of key can also be square toes key, wedge key, tangential keys etc..Another
In one specific embodiment, outer ring 10 is connected with the spline of shell 2.
In the alternative of the present embodiment, the protuberance 100 on outer ring 10 can also be otherwise disposed on outer ring 10
On, for example, protuberance 100 can be integrally formed with outer ring 10.
It should be noted that in the inventive solutions, the type of protuberance should not be limited to key, as long as it is along wheel hub
Bearing it is radially projecting.Accordingly, the type of depressed part also should not be limited to keyway, as long as it can house protuberance
To prevent outer ring and shell from rotating against.
As shown in figure 3, in the present embodiment, hub bearing 1 is two-row ball bearing, hub bearing 1 is included vertically side by side
The first inner ring 11 and the second inner ring 12 set, the first inner ring 11 and the second inner ring 12 are respectively positioned on the radially inner side of outer ring 10.Need
Illustrate, in the inventive solutions, the type of hub bearing 1 should not be limited to the present embodiment, in hub bearing 1
The quantity of inner ring is also not limited to two, for example, inner ring can be one.
Second embodiment
Difference between second embodiment and first embodiment is：As shown in figure 4, in a second embodiment, depressed part
20 are arranged on the outer peripheral face of outer ring 10, and protuberance 100 is arranged on the inner peripheral surface of shell 2, and protuberance 100 is located in depressed part 20,
To realize that anti-in hub bearing circumference of outer ring 10 and shell 2 rotates against cooperation.
In a second embodiment, protuberance 100 and shell 2 can be two separately manufactured parts or one
The entirety of shaping (shown in figure).When protuberance 100 and shell 2 are two separately manufactured parts, shell 2 is provided with corresponding
Depressed part accommodates protuberance 100, in a specific embodiment, the depressed part 20 that is arranged on outer ring 10, is arranged on shell 2
On depressed part be keyway, protuberance 100 is key.
, in the inventive solutions, can be in shell, wheel knowable to summary first embodiment and second embodiment
Depressed part is respectively provided with the outer ring that hub axle is held, it is then prominent using what is be engaged with the depressed part of shell and the depressed part of outer ring simultaneously
Go out portion to realize that anti-in hub bearing circumference of outer ring and shell rotates against cooperation.
It should be noted that in the inventive solutions, the position of protuberance, depressed part on outer ring, shell is not
Side face should be confined to, as long as the shell that its present position can enable to be set on outer ring passes through protuberance and depressed part with outer ring
Cooperation realize and anti-rotate against cooperation.
In the present invention, each embodiment uses laddering literary style, emphasis description and the difference of previous embodiment, each to implement
Same section in example is referred to previous embodiment.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, this is not being departed from
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
