Fig. 9 is the figure of expression present embodiment 3.Present embodiment 3 is a kind of support fixed disk type brakers similarly to Example 1, is the center line C with the moment of torsion receiving portion 33 ' in the middle of it 0Center line C with support main body 1 cTurning to disk, sense of rotation (right side among the figure) the skew back of D constitutes.The basic structure of support main body 1 and embodiment's 1 structure does not have special variation, thus give prosign at this to same structural element, and omit repeat specification.
As shown in Figure 9, in present embodiment 3, each a pair of brake slipper 22,23 is configured to center line C separately 1, C 2In the turn side of D of disk, turn D radially at described disk, 1 P in the zone of the rotating center O of the D that turns with respect to disk and described support main body 1 opposition side intersects.
Like this, even as mentioned above at the center line C of support main body 1 cUnder moment of torsion receiving portion 33 ' the inconsistent situation of centre, as long as each a pair of brake slipper 22,23 is configured to center line C separately 1, C 2In the turn side of D of disk, turn D radially at described disk, 1 P in the zone of the rotating center O of the D that turns with respect to disk and described support main body 1 opposition side intersects, then the occasion of the toe angle of Zhong Jian the moment of torsion receiving portion 33 rotating center O binding of turning less than the intersection point that makes the piece center line and disk.That is to say that even the wall thickness of the moment of torsion receiving portion of piston space 33 attenuate support outer circumferential sides, its forward end can be not damaged yet, can fully guarantee its length.In other words, but because the wall thickness of the moment of torsion receiving portion 33 of attenuate piston space, the corresponding arrangement pitches that just can reduce two pairs of pistons 15,16, its result can realize the miniaturization and of support.
In addition, in above-mentioned three embodiments, illustrated that center line intersection point P, the P ' of each brake slipper are in the center line C of moment of torsion receiving portion 33,47,48,33 0, C 0On situation, but center line intersection point P, the P of each brake slipper not necessarily will be in moment of torsion receiving portion 33,47,48,33 ' center line C 0, C 0On.
In the foregoing description 1 and embodiment 3, moment of torsion receiving portion 33,33 ' center line are by the turn rotating center O of D of disk, but shown in embodiment 2, form each moment of torsion receiving portion 33,33 ' time, the center line of moment of torsion receiving portion 33,33 is also necessary by the turn rotating center O of D of disk.
In above-mentioned three embodiments, the support fixed has been described and has been that support halfbody 2A and 2B are linked all-in-one-piece two element structures, still, even a present invention's support fixed and an element structure or support float type structure also can.
As above described in detail, according to disk type braker of the present invention, by mutual disposed adjacent is set in the rotating center of turning with respect to disk and the regional this simple improvement of described support main body opposition side at the turn intersection point of each brake slipper center line of a side of disk, just can not sacrifice length and subdue the wall thickness of piston space moment of torsion receiving portion to greatest extent, make its optimization, the miniaturization and of support is had very big effect.
