Another kind of mode of execution is: engage sleeves is equipped with brake disc 6 between left brake slipper 1 and the right brake slipper 5, the secondary bar 9 of the waist of left side brake slipper 1 and the second from left joins, top and right second mate's bar 10 of right brake slipper 5 join, and the other end of the secondary bar 9 of the second from left and right second mate's bar 10 links with three secondary bars 11 respectively.The outer end of three secondary bars 11 can link by second mate's bar and slide block 12.
The present invention also can be respectively arranged with left brake pad 13 and right brake pad 14 in the inboard that left brake slipper 1 and right brake slipper 5 match with brake disc 6, the periphery that is sleeved on the brake disc 6 on the axle 8 is provided with alternate bulge loop or groove, is respectively arranged with the bulge loop or corresponding groove of groove or the bulge loop that are provided with brake disc 6 peripheries on left brake pad 13 and the right brake pad 14.Also can be respectively arranged with friction plate 15 at the bulge loop of brake disc 6 periphery settings or the both sides of groove; Or be respectively arranged with friction plate 15 at the groove of left brake pad 13 and right brake pad 14 or the both sides of bulge loop.
The invention has the beneficial effects as follows: it is simple in structure, low cost of manufacture, reliable operation, the equivalent coefficient of friction of non-flat friction brake is more than 10-30 a times of present common friction brake friction factor, and it can be widely used in the break of traffic machinery, metallurgy and chemical machinery, building machinery, lathe and other various heavy machineries.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.

Fig. 4 is that the B-B of Fig. 3 is to the sectional structure schematic representation.
Fig. 5 is the structural representation of the embodiment of the invention 4.
Fig. 6 is the force analysis figure of annular convex ring or groove.
Among the figure: 1-left side brake slipper, 2-left side connecting rod, 3-controls handle, 4-right connecting rod, the right brake slipper of 5-, 6-brake disc, 7-hinge, 8-axle, the secondary bar of 9-the second from left, the right second mate's bar of 10-, 11-three secondary bars, 12-slide block, 13-left side brake pad, the right brake pad of 14-, 15-friction plate.
Embodiment
Consult shown in Figure 6, the inclination angle that brake disc 6 is established its side of trapezoidal bulge loop is θ, suppose that 6 designs of this brake disc have an incomplete annular convex ring and an annular groove to match: when axle 8 was worked under certain rotating speed, left brake slipper 1 and right brake slipper 5 were at (radial system is tight) power F
CEffect under, the normal force of annular groove bi-side is: 2Fn, establishing the annular groove frictional force that the place produces that contacts with incomplete annular convex ring bi-side is F, then
When θ=2.5 °,
When θ=3.5 °,
When θ=5 °,
Can find out that from above calculating when θ is respectively: in the time of 2.5 °, 3.5 °, 5 °, the frictional force that every annular groove rubbing surface produces is respectively 45.8 times, 32.8 times, 23 times of frictional force that planar friction produces.When 5 designs of this left side brake slipper 1 and right brake slipper have N to the incomplete annular convex ring that matches and annular groove, then the frictional force that produces of this brake disc 6 be respectively the frictional force that planar friction produces 45.8K * N doubly, 32.8K * N doubly, 23K * N doubly, K herein is the piece number of brake slipper, and K is 2 in the present embodiment.
Above analysis is to consider that planar friction and non-planar surface friction are the comparison under the situation of commaterial.When the power in bigger 15 its transmission of friction plate of the annular convex ring of left brake slipper 1 and right brake slipper 5 or scrobicular ring both sides viscose glue one deck friction factor can increase significantly, that is to say that the moment of torsion of transmission is bigger.
