Detailed description of the invention
In prior art, after brake pressure is eliminated, friction plate (comprises that piston side friction plate and fist side rubPad) normally because of the passive return of rotation of brake disc, cause noise larger, and can increase the weight of frictionThe wearing and tearing of sheet.
Disk brake in the embodiment of the present invention comprises: brake casing, be arranged on the work of brake casingThe piston of plug in chamber, by the fixing piston side friction plate of the piston mouth of three latch springs and piston. Press in brakingAfter power is eliminated, piston side friction plate can be with piston positive return.
Below in conjunction with specific embodiments and the drawings, the invention will be further described, but should not limit this with thisBright protection domain.
With reference to figure 1, piston side friction plate 12 is fixed by three latch springs 13 and the piston mouth of piston 11, makesPiston side friction plate 12 can be with initiatively return of piston 11.
With reference to figure 2, three latch springs 13 of the present embodiment comprise the edge of main part 130 and autonomous body 1303 spring detents 131,132 that stretch out. As a nonrestrictive example, the spring detent of this three latch spring 13131,132 all towards deviating from the direction bending of main part 130.
In conjunction with Fig. 2 and Fig. 3, the main part 130 of three latch springs 13 is fixedly connected with piston side friction plate 12, exampleAs having installing hole on main part 130, main part 130 is via this installing hole 130 and piston side friction plate12 riveted joints.
In conjunction with Fig. 2 and Fig. 4, as a nonrestrictive example, in the piston mouth of piston 12, ecto-entad dividesBe not provided with piston inner hole inner edge 111 and piston inner hole flange 112 around piston mouth, piston inner hole inner edge 111Be parallel to each other with the bearing of trend of piston inner hole flange 112. 3 spring detents in three latch springs 13 respectively with workThe physical dimension coupling of plug mouthful endoporus, thus three latch springs 13 are fixed with piston, and then make piston sideFriction plate is axially fixed on piston along piston. In the present embodiment, spring detent 131 is hooked in piston inner holeOn edge 111, bear the pressure of piston inner hole inner edge 111, it is protruding that other 2 spring detents 132 are hooked in piston inner holeOn edge 112, bear the pressure of piston inner hole flange 112.
With reference to figure 5, Fig. 5 shows the overall appearance structure of the disk brake of the present embodiment, and wherein, fist side is rubbedPad is fixed by three latch springs 20 and the fist side of brake casing 10, makes the fist side friction plate can be with brakeHousing 10 is active return together.
With reference to figure 6, Fig. 6 shows the structure of three latch springs 20 that connect fist side friction plate, comprises main part 200And 3 spring detents 201,202 that independently body 200 stretches out. As a nonrestrictive example, whereinA spring detent 201 is towards deviating from the direction bending of main part 200, and other 2 spring detents 202 are towards pointing to main part200 direction bending.
In conjunction with Fig. 6 and Fig. 7, the main part of three latch springs 20 200 is fixing with fist side friction plate 21, the two consolidateDetermining mode can be also for example riveted joint.
In conjunction with Fig. 6 and Fig. 8, as a nonrestrictive example, the fist side of brake casing 10 has bayonet socket3 spring detents 201,202 of 101, three latch springs 13 are connected in this bayonet socket 101, make brake casing10 and the return of fist side friction plate be consistent.
With reference to figure 9 and Figure 10, as a preferred embodiment, on the outer wall of piston 11, be fixed with sealing ring113, on the plunger shaft inwall of brake casing 10, there is groove, sealing ring 113 is placed in the recessed of plunger shaft inwallIn groove. Shown in Fig. 9 is the disk brake under non-on-position, and deformation does not occur sealing ring 113; FigureShown in 10 is the disk brake under on-position, and piston 11 moves under brake pressure effect, sealing ring 113Be subject to the restriction of groove and elastic deformation occurs, in the time that brake pressure is eliminated, sealing ring 113 will restore to the original state, fromAnd drive piston 113 to be returned to original initial position.
It should be noted that, although in the present embodiment, what three latch springs of connection piston side friction plate adopted isStructure shown in Fig. 2, and what connect that three latch springs of fist side friction plate adopt is the structure shown in Fig. 6, but thisThose skilled in the art should be appreciated that the concrete knot of three latch springs for connecting piston side friction plate and fist side friction plateStructure is not limited to this, can also adopt three latch springs 30 as shown in figure 11 of example, it comprise main part 300 and3 spring detents 301 that autonomous body 300 stretches out, these 3 spring detents 301 are all towards the side that points to main part 300To bending. In addition, in the time adopting three latch spring of different structure, the shape of piston inner hole and/or brake casingSize also will be carried out corresponding change, matches, to achieve a fixed connection with shape, the size of three latch springs.
Although the present invention with preferred embodiment openly as above, it is not for limiting the present invention, Ren HebenThose skilled in the art without departing from the spirit and scope of the present invention, can make possible variation and repairChange, therefore protection scope of the present invention should be as the criterion with the scope that the claims in the present invention were defined.
