Specific embodiment
Fig. 1 is referred to, inventor of the present utility model is in order to be able to preferably manage the technical solution of the utility model Solution, below by specifically embodiment, 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 present utility model, including clutch-pedal support 1 and It is socketed in the 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 present utility model is in the absence of destroyed risk, anti-rotation stopper slot 23, annular table Chamfering on stage structure 24, axial limiting block 25 and axial limiting part 14 can play good transitional function, further drop The destroyed risk of low clutch pedal axle sleeve self-locking structure, and avoid what the claw of the axle sleeve 2 of claw structure cannot be opened Problem.
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 present utility model is by improving between axle sleeve 2 and clutch-pedal support 1 Fit structure, can either reduce the installation time and percent defective of operative employee, make again axle sleeve 2 using on the premise of plastics not It is fragile, meet light-weighted requirement, and reduce product cost.
A kind of axle sleeve 2 of clutch pedal axle sleeve self-locking structure of the present utility model uses the knot of the monoblock type of injection moulding Structure, the local wall thickness of its pedal end is thicker, under equal stressing conditions, than using claw structure axle sleeve 2 mechanical property more By force, mechanical property is 1.5~2 times using the axle sleeve of claw structure, improves the life cycle and peace of clutch pedal assembly part Quan Xing.Therefore a kind of clutch pedal axle sleeve self-locking structure of the present utility model can be carried for assembling more energetically plus Carry without damaging structure, largely reduce the risk of boss failure, improve accepted product percentage.
A kind of clutch pedal axle sleeve self-locking structure of the present utility model, can save 3~5s of installation time, for producing per year Measure for the manufacturing enterprise for 500000 sets, be equivalent to save the time of 416.67h, this maintenance to manufacturing enterprise into Sheet, energy cost, cost of labor, management cost can all be greatlyd save.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above Change, the modification of embodiment will all fall in Claims scope of the present utility model.
