Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is the structure top view according to a kind of wheel bearing assembly shown in an exemplary embodiment, as it is shown in figure 1,
This wheel bearing assembly includes the first supporting part 110 and the second supporting part 120.
First supporting part 110 and the second supporting part 120 provide running section, wherein, this first carrying for this vehicle simultaneously
Portion 110 is provided to the left side tire running of vehicle, and this second supporting part 120 is provided to the right side tire running of this vehicle.
Fig. 2 is the cross sectional side view according to a kind of wheel bearing assembly shown in an exemplary embodiment, as in figure 2 it is shown,
The upper surface of the first supporting part 110a and the second supporting part 120a is respectively formed the sine surface that Cycle Length is identical, wherein, sinusoidal
The Cycle Length of curved surface is relevant to the spring carried mass resonant frequency of predefined type vehicle.
It should be noted that the wheel bearing assembly said in the present embodiment can be drive test examination of jolting vehicle
Jolt line structure.
In sum, the wheel bearing assembly that the disclosure provides, by the first supporting part and the upper surface of the second supporting part
It is respectively formed the sine surface that Cycle Length is identical, due to Cycle Length and the spring carried mass of predefined type vehicle of this sine surface
Resonant frequency is correlated with, and therefore solves the most same road of jolting and is common to the vehicle of each model, but the model difference of vehicle is right
The parameter answered is likely to difference, use same road of jolting the vehicle of each model is jolted drive test examination, be likely to result in car
The problem that the Stress Release of leaf spring is insufficient, has reached the spring carried mass resonant frequency according to vehicle and has determined with this vehicle relatively
Drive test examination of jolting, the fully effect of the stress of release vehicle leaf spring is carried out for applicable road of jolting.
In a kind of possible implementation, referring also to Fig. 1, the first supporting part 110 and the upper table of this second supporting part 120
Face is respectively formed the sine surface that Cycle Length is identical, represents the half cycle length of sine surface with rectangular area, such as in figure
If region 110b is crest, region 110c is then trough.In order to more fully discharge the stress of vehicle leaf spring, sine surface

During predefined type vehicle travels on wheel bearing assembly, this predefined type vehicle can replace to tilt forwardly
State and sweptback state, reached the effect of the stress of release vehicle leaf spring more fully.
For example, if the wheelbase between the front-wheel of predefined type vehicle and trailing wheel is 2.67 (m), then sine surface
Cycle Length isAs N=1, L=5.34 (m), as N=2, L=1.78 (m).
Accordingly, the Cycle Length of the sine surface formed when the upper surface of the first supporting part and the second supporting part is
Time 0.89 (m), the wheelbase between front-wheel and trailing wheel isSo wheelbase between front-wheel and trailing wheel is
The predefined type vehicle of 0.445*N (m) on this wheel bearing assembly in driving process, all can replace to tilt forwardly
State and sweptback state.
Optionally, the sine surface of sine surface and the second supporting part upper surface formation that the first supporting part upper surface is formed
Curved surface in relative position differs half sinusoidal cycles.
In order to discharge the stress of vehicle leaf spring more fully, the first supporting part and the second supporting part can be able to be designed
Become identical sine surface, the first supporting part and the second supporting part are differed half sinusoidal cycles and places side by side.Referring also to Fig. 1, when
During region 110b crest in the first supporting part 110, with relative for region 110b the second supporting part in the first supporting part 110
Region 120b in 120 is trough.When the region 110c in the first supporting part 110 is trough, and in the first supporting part 110
The region 120c in the second supporting part 120 relative for region 110c is crest.
In order to discharge the stress of vehicle leaf spring more fully, it is also possible to the first supporting part and the second supporting part are designed to phase
Differ from the sine surface of half sinusoidal cycles, the first supporting part and the second supporting part are placed side by side, it is also possible to reach to make first to hold
The sine surface that the sine surface of load portion upper surface formation and the second supporting part upper surface are formed is in the curved surface phase of relative position
Differ from the effect of half sinusoidal cycles.
When the sine surface of the first supporting part upper surface formation and the sine surface of the second supporting part upper surface formation are in phase
When the curved surface of position is differed half sinusoidal cycles, region residing for the left side tire of preset vehicle and tire side, right side is ripple
Region residing for side, peak is trough, during predefined type vehicle travels on wheel bearing assembly, and this predefined type car
Can alternately be in the state being tilted to the left and the state being tilted to the right, reach to discharge more fully the stress of vehicle leaf spring
Effect.
The Cycle Length of the sine surface formed when the upper surface of the first supporting part and the second supporting part and predefined type
Wheelbase between the front-wheel of vehicle and trailing wheel is relevant, and the first supporting part upper surface formed sine surface and the second supporting part on
