Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
The present invention discloses a kind of disc-like brake structure, comprising: caliper bracket 1, circlip 2 and friction plate 3.
Caliper bracket 1 is formed with installation cavity symmetrical above and belowly；There are two the tools of circlip 2, is separately mounted in installation cavity, circlip
2 have recessed function part, and function part front forms groove area 21, and the back side of function part is fixed in installation cavity, function part
Two sides, are symmetrically formed one group of spring leaf 22, spring leaf 22, and spring leaf 22 opposite to each other, and is located on groove area 21；Friction plate
3 settings are slided between circlip 2, and in groove area 21,22 extrusion friction piece 3 of spring leaf.
Friction plate 3 can be set two, and two spring leafs 22 in one group respectively drive a friction plate 3.Friction plate 3
Top and bottom be respectively formed clamping portion, which is slidably matched with groove area 21, and the width of clamping portion is less than groove area
21 width.
In use, the bottom surface or top surface of friction plate 3 are contacted with the bottom surface of groove area 21, the side of friction plate 3, with spring leaf
22 contacts, in general, system hydraulic drive piston motion, piston pushes two friction plates 3 to mutually close side in braking process
To when movement, corresponding 22 deformation of spring leaf can be made simultaneously.After end of braking, system is without hydraulic, piston self-return, spring leaf
22 generate elastic restoring force by elastic deformation, help two friction plates 3 to mutually separate direction return, reduce the stagnant power of support
Square.
Between the side wall for the function part that spring leaf 22 can be corresponding, damping structure is can be set in corresponding such case,
Such as the structures such as spring, rubber column, to assist it to realize, elasticity is restored, and provides better elastic restoring force for friction plate 3, simultaneously
It is able to extend the service life of spring leaf 22.
Spring leaf 22 and a side wall of function part are structure as a whole, and are bent to form from the side wall of function part.Spring leaf 22
Close to the part of the side wall of function part, bending ear 23 is formed, the outer wall of bending ear 23 is arc-shaped.
Spring leaf 22 is upturned after bending ear 23, and the height of tilting is higher than the height of bending ear 23.
In addition, after prolonged use, fatigue strength reduces, it can be by adjusting the angle of bending ear 23, to adjust bullet
The ability to work of reed 22 improves its service life.
On the side wall that function part is connected with the spring leaf 22, on the inner face towards the spring leaf 22, it is formed with multiple
Wing 24 is stuck up, the tilting height for sticking up wing 24 is adjustable, with the scope of activities being used to when limited spring piece 22 is extruded.
The size of installation cavity is less than or equal to the size at the back side of function part.When installation, squeeze function portion makes it that shape slightly occur
Become, snap fit onto installation cavity, on the one hand can fix clamping, another instant noodles make spring leaf 22 be capable of providing preferably elasticity time
Multiple power.
An interspace is formed in the middle part of circlip 2, two spring leafs 22 are located at the two sides in gap.The side of function part two sides
Wall, is respectively formed outside bending part, and bending part can be clamped or be fixed in caliper bracket 1.
Above-mentioned bending part, is respectively formed with hollow hole, to reduce weight, while can be improved its rigidity, also, pass through
The hollow hole can be connected in the corresponding mounting post of caliper bracket 1, to realize that positioning, placement jump.
On the bending part of side, reversed clamping bending 25 can also be formed, is extended to the direction of function part, and to
The bottom of function part is bent, during installation, to snap fit onto the correspondence clamping groove to caliper bracket 1.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
