Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope.
As shown in Fig. 4 ~ 9, generator clutch belt pulley, including columned power transmission shaft 1, unilateral bearing component 2 and biography
Runner hub 3, unilateral bearing component 2 are arranged between the outer ring of power transmission shaft 1 and the inner ring of power wheel hub 3, for moving power wheel hub 3
Power one-way transmission is to power transmission shaft 1；Unilateral bearing component 2 includes star-wheel 21, retainer 22 and the overcoat set gradually from the inside to the outside
Circle 23, retainer 22 is in axial direction evenly distributed with a plurality of mounting groove, and it is circular that section is provided with every mounting groove
Needle roller 24 and flexible member 25, in the present embodiment, curved surface shell fragment are selected as flexible member 25, what is be supported to needle roller 24
During be not susceptible to axial skew because curved surface shell fragment is easily bent in minimum rigidity plane, and in another direction
It is upper that there is big tensible rigidity and bending stiffness；The section of outer collar 23 is " ㄇ " type structure, is effectively guaranteed unilateral bearing group
The compactedness of the structure of part 2, avoid it and axial float occurs；Star-wheel 21 is fixed on power transmission shaft by the connected mode of interference fit
On 1 external cylindrical surface, working curved surface 26 one-to-one with needle roller 24, working curved surface 26 and outer collar are provided with the outer wall of star-wheel 21
Inwall forms the space that height is gradually reduced, and the one end of flexible member 25 is connected with retainer 22, and the other end connects with needle roller 24
Connect, be located at for needle roller 24 to be supported in space.
Two groups of bearings 5 are additionally provided between the outer ring of power transmission shaft 1 and the inner ring of power wheel hub 3, two groups of bearings 5 are respectively arranged at list
To the both sides of bearing assembly 2, its middle (center) bearing 5 is ball bearing.
During specific works, rotated by engine output end by belt drive power wheel hub 3, as shown in fig. 6, by drive
Hub 3 by be interference fitted drive outer collar 23 rotate, so as to by outer collar 23 drive needle roller 24 along working curved surface 26 to its with
The space motion that outer collar inwall is formed, and the side that the direction of motion is gradually reduced towards height, it is certain when moving to
During position, the clamping between working curved surface 26 and the inner ring of outer collar 23 of needle roller 24, therefore the rotation of power wheel hub 3 can be passed to star
Wheel 21, star-wheel 21 drive power transmission shaft 1 to rotate by the interference fit between power transmission shaft 1, are sent out so as to drive generator to rotate
Electricity, wherein the electric power part sent is stored in storage battery, another part is then used for in-car electrical equipment operating, in this process,
When engine produces the fluctuation of speed, when especially slowing down, power wheel hub 3 slows down together with engine, and the now meeting of needle roller 24 exists
The lateral movement gradually increased to spatial movement inner height under the drive for the inner ring of outer collar 23 that speed reduces, release bent to work
Face 26 and the clamping of outer collar 23, and star-wheel 21 and power transmission shaft 1, because inertia maintains former rotational speed, therefore outer collar 23 is with passing
Speed difference is produced between star-wheel 21 outside moving axis 1, so as to avoid engine speed fluctuations from especially sending out motor head annex
The adverse effect of motor and belt life.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
