Description
Technical field
The utility model relates to a kind of folding device, particularly a kind of folding device with axle bush that is used for folding cycle.
Background technology
Folding cycle is a kind of bicycle that has foldable part at least, traditional folding cycle, and it utilizes the folding device at central frame beam, front portion or rear portion, so that it reaches less package size.The folding bicycle of middle vehicle frame can make its doubling to reduce assembled length; Vehicle frame folding bicycle in rear portion can make its trailing wheel folding, relatively also can reduce assembled length; And anterior folding bicycle adopts the mode that makes its turning member down folding, to reduce assembled height.
Traditional folding cycle can use folding device usually at least one folding position, folding device includes first pedestal, second pedestal, pivot and operating handle.First pedestal and second pedestal approximately are level and all are welded on the two halves part of vehicle frame; May make with aluminium or alloy between the extendible portion of pedestal and handgrip or back handgrip and vehicle frame; Pivot makes its close installation by processing, and in order to link first pedestal and second pedestal, this pivot is made with steel usually.When operating handle was closed, folding device kept closing under the state of driving; When operating handle was opened, folding device was opened and is formed folded state.
When using and operate folding device, because intermetallic can directly wear and tear each other, so pivot may damage first pedestal and second pedestal, in case continue, the situation that folding device fluffs and dies down will take place; In addition, the twisting resistance that forms because of vehicle frame will cause producing stress on pivot, so the life-span of folding device and vehicle frame just will be restricted because of wearing and tearing like this; In case folding device fluffs, even twisting resistance increases pivot flexure will be fractureed, and the vibration that causes will cause folding device to send noisy sound, more quicken the wearing and tearing of folding device; Similarly, when pivot and pedestal are that different metal is made, soft usually metal (for example aluminium) is used on the vehicle frame, and harder metal (for example steel) mill that is used on the pivot is ruined; Similarly, when directly touching down mutually each other, different metals has more may blocking.Because pivot and cycle frame integrator, so may spend a large amount of money and inconvenience replacing with, the while will be increased the weight of environmental problem when vehicle frame is dropped.In addition, in theory, when torsion (application force when driving produces) when being applied to the folding device of bicycle, moment of deflection will be by the line of centers effect; Yet these all are that hypothesis is under fare-you-well.Moment of deflection will be at first by the position generation effect of the most approaching axle (pivot), because the very difficult control of the accuracy of making, so the position of pivot extreme end also is difficult to prediction, therefore, the folding device of some folding cycles weares and teares easily and breaks down.

The specific embodiment
Please refer to shown in Figure 1, a kind of folding cycle 9 that the utility model provides with folding device of axle bush, have the folding device 1 in order to the axle bush of two separate parts (for example vehicle frame, handgrip frame) that link folding cycle, this folding device 1 can be applicable to the appropriate location of handgrip frame 2 or cycle frame 3.See also Fig. 2 and shown in Figure 5, the utility model is applied to the folding device 1 on the vehicle frame 3.
See also Fig. 2 to shown in Figure 5, a kind of folding cycle that the utility model provides with folding device of axle bush, wherein, folding device 1 comprises first pedestal 10, second pedestal 20 and securing arrangement 30.Second pedestal 20 articulates first pedestal 10; The securing arrangement 30 and first pedestal 10 and second pedestal 20 articulate, with so that first pedestal 10 selectively lock with second pedestal 20 or separate.Securing arrangement 30 in the present embodiment comprises an operating handle 31 and a bar 32, and the two ends of bar 32 are articulated in second pedestal 20 and operating handle 31 respectively; Operating handle 31 has leader's pivot 311, and it is articulated in two holes 15 on first pedestal 10, and therefore, first pedestal 10, second pedestal 20, operating handle 31 and bar 32 have formed four linkage rod group as tradition.Because utilizing the folding device 1 of this four linkage rod group (first pedestal 10 of vehicle frame 3, second pedestal 20, operating handle 31 and the bar 32 of vehicle frame 3) is known technology, for example: No. the 200620059004th, Chinese patent publication number, it has been described in detail the principle of work of relevant pivot, so seldom give unnecessary details at this.
The utility model provides a kind of main purpose of folding cycle of the folding device with axle bush about the hookup mechanism of 20 of first pedestal 10 and second pedestals.
Folding device 1 has two pivots 80 that correspond respectively to second hole 221, and each pivot 80 all has pivot screw thread 81, and this pivot screw thread 81 can correspond to the negative thread 122 in first hole 121 respectively.
Folding device 1 has two axle bushes 70, and this axle bush corresponds to second hole 221 respectively, and each axle bush 70 is for ring-type and a flange 71 is arranged, and is preferable, but axle bush 70 is an auto-oiled axle bush 70, in order to guarantee axle bush 70 in use, can operate reposefully.
Each axle bush 70 all is installed in corresponding second hole 221, and flange 71 is accurate in order to guarantee the position, prevents that simultaneously axle bush 70 from excessively inserting.And first pivotal block 12 is positioned over notch part 223 and itself and 22 arrangements of second pivotal block in line, and therefore, first pivotal block 12 and second pivotal block 22 are meshing with each other in concavo-convex mode.Pivot 80 sees through separately pairing first hole 121, axle bush 70 and second hole 221 and inserts.Owing to all there is in each first hole 121 negative thread 122 to exist, and each pivot 80 all has pivot screw thread 81, so each pivot 80 all can be fastened on its pairing first hole 121.
Be noted that in present embodiment, each axle bush 70 is arranged at salient 222, please refer to shown in Figure 5.Therefore, axle bush 70 is separated by the length L 1 of this notch part 223.Generally speaking, L1 is being preferable between 10 millimeters to 150 millimeters; If folding device 1 is applied in the middle of the vehicle frame 3, its preferable length L 1 can be between 20 millimeters to 150 millimeters; Yet in case folding device 1 is applied on the handgrip frame 2, folding device will become littler on utilizing, and at this moment preferable length is between 10 millimeters to 60 millimeters.In theory, when bestowing folding device 1 twisting resistance, the line of centers by pivot 80 has a moment (F * L) produce; Yet actually, moment will act on the position of the most close pivot 80.According to present embodiment, its hithermost position be positioned at two axle bushes 70 near, therefore, the moment of folding device is measurable, however this is the manufacturing technology that involves standard, to such an extent as to the abrasion action that has a little is on folding device 1, to influence its service life.Therefore, the quality of folding device 1 is that the time limit employed with it is closely bound up.Say that further because this pivot 80 be removable, so wear and tear when breaking down when axle bush 70, axle bush 70 also can be taken away, make folding device more durable and need not be whole replacing.Say that further axle bush can directly touch the part of folding device 1 aluminum in order to the pivot 80 of avoiding steel, block the part of aluminum with the pivot 80 that prevents steel.
Explanation principle of the present utility model and effect thereof that the foregoing description is only exemplary, but not be used to limit protection domain of the present utility model.Any personage who is familiar with this technology all can be under know-why of the present utility model and spirit, and embodiment is made an amendment and changes.For example, the utility model not only can be applied to four linkage rod group, also can be applicable to three linkage rod group, and for example U.S. Patent number the 7th, 762, and 570 and 6,336, No. 649.Be noted that though folding device 1 utilizes pair of pivot 80 and pair of corresponding axle bush 70, both also can simply change into one.
