Specific embodiment
Fig. 1 is referred to, the present inventor is led to below in order to be able to preferably understand technical scheme
Specifically embodiment is crossed, and is described in detail with reference to accompanying drawing：
Refer to Fig. 1, a kind of clutch pedal axle sleeve self-locking structure of the invention, including clutch-pedal support 1 and socket
Axle sleeve 2 in the axis hole 11 of clutch-pedal support 1.
The end face of the clutch end of its bottom bracket axle 2 is provided with a flange arrangement 21 coaxial with axle sleeve 2.Flange arrangement 21
Excircle on the uniform two arc-shaped limit bars 22 tangent with the excircle of flange arrangement 21, the footpath of arc-shaped limit bar 22 is inside
Side forms the anti-rotation stopper slot 23 coaxial with the pivot of axle sleeve 2.The clutch end face of clutch-pedal support 1 be provided with two with
The spacing reinforcement 12 of arc anti-rotation of the central coaxial of axis hole 11, two spacing reinforcements 12 of arc anti-rotation can be limited with two anti-rotations
The position corresponding clamping of groove 23.By two spacing reinforcements 12 of two arc anti-rotations of the correspondence clamping of anti-rotation stopper slot 23, can prevent
Rotation of the axle sleeve 2 in axis hole 11.
The uniformly radiation of some flange arrangements 21 for support sleeve 2 on the clutch end face of clutch-pedal support 1 simultaneously
The spacing reinforcement 13 of shape.The end face correspondence spacing face of reinforcement 13 radial with of two free ends of arc-shaped limit bar 22 connects
Touch, so as to further prevent rotation of the axle sleeve 2 in axis hole 2.
The excircle of the pedal end of axle sleeve 2 is provided with a ring-shaped step structure 24, makes the section of the pedal end face of axle sleeve 2
Sectional area of the product less than the clutch end face of axle sleeve 2.Around the circumference of the step wall of ring-shaped step structure 24, uniform some axial directions
Limited block 25.Axial limiting gap is formed between the bottom surface of each axial limiting block 25 and the step surface of ring-shaped step structure 24
26。
Around the hole wall of the pedal side of the axis hole 11 of clutch-pedal support 1, uniform some axial limiting parts 14, axial limiting
Part 14 is corresponded and is connected in the axial limiting gap 26 of axle sleeve 2, and is excessively coordinated with axial limiting gap 26.
Therefore, by the cooperation between the axial limiting part 14 of axis hole 11 and axial limiting gap 26, axle sleeve 2 can be prevented
Axial movement, so as to axle sleeve 2 is fixed in axis hole 11.
Rotary sleeve 2 is only needed in assembling process, by the corresponding spacing reinforcement of clamping arc anti-rotation of anti-rotation stopper slot 23
Muscle 12, and the end face of the free end of arc-shaped limit bar 22 is contacted with the radial face of spacing reinforcement 13, axle sleeve 2 can be prevented in axle
Rotation in hole 11.Axial limiting part 14 on the hole wall of axis hole 11 is connected in the axial limiting gap 26 of axle sleeve 2, thus
Complete the self-locking of axle sleeve 2.Meanwhile, the free end of arc-shaped limit bar 22 is inclined to the pedal end of axle sleeve 2, is easy to arc-shaped limit
The end face of the free end of bar 22 is contacted with the radial face of spacing reinforcement 13.Therefore machine or operative employee need not take time to carry out
Calibration, it is only necessary to spend 3~5s, you can the position of positioning shaft sleeve 2, reduces the human error of time cost and operative employee.Simultaneously
A kind of clutch pedal axle sleeve self-locking structure of the invention is in the absence of destroyed risk, anti-rotation stopper slot 23, ring-shaped step knot
Chamfering on structure 24, axial limiting block 25 and axial limiting part 14 can play good transitional function, further reduce from
The destroyed risk of clutch pedal axle sleeve self-locking structure, and avoid the problem that the claw of the axle sleeve 2 of claw structure cannot be opened.
Meanwhile, be evenly equipped with the periphery wall of the clutch side of axle sleeve 2 can with the hole wall interference fit of axis hole 11, with axle sleeve
2 axially in parallel axial fins 27.The effect of axial fin 27 is：Strengthen the cooperation between axle sleeve 2 and clutch-pedal support 1, make
Even if axle sleeve 2 is subject to horizontal force in the process of running to obtain clutch pedal, also will not between axle sleeve 2 and clutch-pedal support 1
Sliding is produced, the security of clutch pedal is further ensured that.
Meanwhile, the inner periphery socket rotation power-assisted nut 28 of the clutch end of axle sleeve 2 helps axle sleeve 2 to complete rotary self-locking.
A kind of clutch pedal axle sleeve self-locking structure of the invention is by improving the cooperation between axle sleeve 2 and clutch-pedal support 1
Structure, can either reduce the installation time and percent defective of operative employee, axle sleeve 2 is being used not rapid wear on the premise of plastics again
It is bad, meet light-weighted requirement, and reduce product cost.
A kind of axle sleeve 2 of clutch pedal axle sleeve self-locking structure of the invention uses the structure of the monoblock type of injection moulding,
The local wall thickness of its pedal end is thicker, and under equal stressing conditions, the mechanical property than the axle sleeve 2 using claw structure is stronger,
Mechanical property is 1.5~2 times using the axle sleeve of claw structure, improves the life cycle and safety of clutch pedal assembly part
Property.Therefore a kind of clutch pedal axle sleeve self-locking structure of the invention can be carried for assembling loading more energetically without
Structure can be damaged, the risk of boss failure is largely reduced, accepted product percentage is improved.
A kind of clutch pedal axle sleeve self-locking structure of the invention, can save 3~5s of installation time, be for annual production
For 500000 sets of manufacturing enterprise, it is equivalent to save the time of 416.67h, this maintenance cost, energy to manufacturing enterprise
Source cost, cost of labor, management cost can all be greatlyd save.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as being limitation of the invention, as long as in spirit of the invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
