In disk type braker according to above-mentioned relevant invention, different with the traditional structure shown in Figure 14-15, lining pad pin 35 and clamp 1a do not have male screw portion or female thread part on it supporting lining pad pin 35, and described lining pad pin 35 is inserted among a pair of lining pad 4a, the 4b with at clamp 1a upper support lining pad.Promptly, in the structure of above-mentioned relevant invention, for at clamp 1a upper support lining pad pin 35, the two end portions of lining pad pin 35 is inserted among the first through hole 30a, the 30b, the described first through hole 30a, 30b are respectively formed in the third and fourth clamp arm 28,29 of clamp 1a, with supported.Correspondingly, there is no need on the two end portions of lining pad pin 35 and the first through hole 30a, 30b, to form male screw portion or female thread part.
In addition, in above-mentioned relevant invention, flange 36 is being formed on the end portion of lining pad pin 35 on the direction longitudinally, and clip 38,38 is being locked on the longitudinal direction of lining pad pin 35 on two positions to prevent that lining pad pin 35 from separating from clamp 1a.That is, outside lining pad pin 35 moves to clamp 1a (downside to Figure 18), the side surface collision of the side surface of arbitrary relative the 4th clamp arm 29 of flange 36 and outer folder 38 or the first lining pad arm 31 of interior lining pad 4a.Correspondingly, the lining pad pin does not move to outside the clamp.In addition, in the time of within lining pad pin 35 moves to clamp 1a (upside to Figure 18), the side surface collision of the side surface of arbitrary relative the 3rd clamp arm 28 of at least one pair of clip 38,38 or the 4th clamp arm 29.Correspondingly, the lining pad pin does not move within the clamp.Like this, in the structure of above-mentioned relevant invention, move, just can prevent that the lining pad pin from moving within the clamp outside the latter by two holding members even go up in any direction when lining pad pin 35.Correspondingly, the structure of Xiang Guan invention has safety protection (fail-safe) structure.
In addition, in the structure of above-mentioned related invention, when lining pad pin 35 was assembled among the clamp 1a, the end sections of the lining pad pin 35 relative with flange 36 was inserted into the first through hole 30a, the 30b in the clamp arm 28,29 that is respectively formed at clamp 1a and is respectively formed in second through hole 33,33 among lining pad 4a, the 4b.After inserting, clip 38,38 is locked in respectively in the locking aperture 37,37, and described locking aperture 37,37 is formed on the position of the lining pad pin 35 between the 4th clamp arm 29 and the interior lining pad 4a and projects into from the 3rd clamp arm 38 on the part in the outside.Because each locking aperture 37,37 do not cover clamp 1a, just can be at an easy rate locking clamp 38,38 in locking aperture respectively.
Like this, different with traditional structure shown in Figure 14,15, prevent that lining pad pin 35 is used the disk type braker of relevant invention from the safety protection structure that clamp 1a separates.But helical thread portion is not formed on part and the lining pad pin 35 of the clamp 1a that is used to support lining pad pin 35.For this reason, in the process of the manufacturing of disk type braker, just may reduce or do not carry out the screw thread course of working, reduce manufacture cost thus.
But in the disk type braker of related invention, when the workman assembled lining pad pin 35 on clamp 1a, lining pad pin 35 may be assembled on incorrect position.Correspondingly, incorrect assembling just may take place, and for the described space of clamp 1a being installed hour, if incorrect assembling takes place, each lining pad 4a, 4b just may not push the both sides of rotor 3 satisfactorily therein.After this, for this reason, will describe.Promptly, as shown in Figure 19, installing such as big being enough in the space in the vehicle of motorcycle under the situation of clamp 1a or a pair of lining pad 4a, 4b, and the length of clamp 1a is fully long on axial direction, if locking aperture 37 and 37 is by proper arrangement, even lining pad pin 35 is assembled on incorrect direction, problem also is difficult to take place.In this case, the internal surface of the 3rd clamp arm 28 (the right surface among Figure 19) and constitute between the outer surface (left surface among Figure 19) of pressure plate 13 of external friction pad 4b and at the outer surface (left surface among Figure 19) of the 4th clamp arm 29 and in constituting between the internal surface (right side among Figure 19 is surperficial) of the pressure plate 13 of lining pad 4a the sufficient space of acquisition (be easy to enlarge inside and outside gap delta 1, δ

2).Correspondingly, in the process of the assembling of lining pad pin 35, as shown in figure 20, different with situation as shown in Figure 19, the end sections of the lining pad pin 35 relative with flange 36 is inserted into the first through hole 30a, the 30b in the clamp arm 28,29 that is respectively formed at clamp 1a from the outside (left side Figure 20) of clamp 1a, and is respectively formed in second through hole 33,33 among lining pad 4a, the 4b.Correspondingly, even it is supported in clamp 1a to work as lining pad pin 35, if locking aperture 37,37 is appropriately positioned, just can be on lining pad pin 35 locking clamp 38,38, and be not subjected to such as the other parts of lining pad 4a, 4b and the interference of clip itself.Like this, under the situation of the bigger installation clamp in space 1a, even when lining pad pin 35 is in any direction assembled, problem also is difficult to take place therein.
But according to the structure of vehicle, such situation is arranged: the space that clamp 1a and lining pad 4a, 4b wherein are installed is very little, and the length of clamp 1a is not sufficient length in the axial direction.In this case, as shown in figure 21, so a kind of situation is arranged: wherein can not and constitute between the side surface of pressure plate 13 of external friction pad 4b and obtain sufficient room (external series gap δ at the side surface of the 3rd clamp arm 28
2Less).In this case, the distance L between the outer surface of the pressure plate 13 of the outer surface of the 3rd clamp arm 28 and formation external friction pad 4b
1Can be provided with less than the outer surface of the flange 36 that is formed on lining pad pin 35 at an easy rate and press from both sides distance L between 38 outward
2(L
1＜L
2).As a result, as shown in Figure 22, the end sections of the lining pad pin 35 relative with flange 36 is inserted into through hole 30a, the 30b and 33 that is respectively formed on clamp arm 28 and lining pad 4a, the 4b from the outside of clamp 1a.For this reason, when lining pad pin 35 is supported in clamp 1a, after clamp 1a is assembled into vehicle, if the clip 38 that is locked on the part of the lining pad pin 35 with flange 36 contacts with external friction pad 4b, it is that wherein lining pad 4a is easy to the surface tilt of relative rotor 3 that individual problem is arranged.In this case, each lining pad 4a, 4b may not push two surfaces of rotor 3 satisfactorily.
Consider the above-mentioned fact, can not and constitute between the side surface of pressure plate 13 of external friction pad 4b at the side surface of the 3rd clamp arm 28 therein and obtain the space fully, just be necessary the direction of when assembling lining pad pin 35, regulating lining pad pin 35.Simultaneously, in the structure of above-mentioned relevant invention, even when the workman is assembling lining pad pin 35 on clamp 1a on the incorrect direction, just can be on lining pad pin 35 locking clamp 38,38, such situation is arranged thus, wherein lining pad pin 35 is assembled on incorrect direction, and the clamp 1a that has the lining pad pin of assembling 35 then on incorrect direction assembles with rotor 3 in vehicle.In this case, the time that need re-assembly.
