Background technology
The brake of single hoof (One Shoe) be typically all ring-type integration list hoof structure, its performance of parking brake with become
This saving effect is more outstanding compared with double shoe types.
Fig. 1 is the explanation with regard to traditional single hoof brake structure, as illustrated, (not shown)BrakeDrum extruding generates system
The hoof 500 of power is integrated, and forms the adjustment assembly structure of braking maneuver using the two ends that the tension force of bracing wire opens above-mentioned hoof 500
The decomposing state of part.
Above-mentioned adjustment assembly by Torque plate 502 and is installed on the tappet 504 of this Torque plate 502 side and is installed on opposite side
Adjusting screw 506, between above-mentioned tappet 504 and adjusting screw 506, the bar 508 installed and lever 510 are constituted.
Fig. 2 is explanation, above-mentioned tappet 504 and the adjusting screw of confined state with regard to above-mentioned adjustment assembly and its action
506 two ends being close to above-mentioned hoof 500 respectively, above-mentioned lever 510 is connected with bracing wire, can be with mobile above-mentioned bar by bracing wire
508, so that above-mentioned tappet 504 and above-mentioned adjusting screw 506 is opened the two ends of above-mentioned hoof 500 and form braking.
But, single hoof 500 parking brake that structure rotates as described above is, between above-mentioned lever 510 and tappet 504
Bar 508, as shown in figure 3, formed by cylindrical two ends press spherical shape processing semi-spherical shape, its material be high-carbon chromium steel,
There is making hardly possible and the high defect of cost of manufacture.
And it is above-mentionedThick stickHemispherical groove portion 512 should be had on bar 510, to fix one end of above-mentioned bar 508, therefore above-mentioned thick stick
Above-mentioned bar 508 department of assembly's minimum of bar 510 will reach more than certain level, and the position of contrary connecting stay wire is then drawn for ease of assembling
Line, the complex structure that its thickness should be greater than above-mentioned minimum thickness and there is above-mentioned lever 510 leads to make difficult and univalent rising
Problem.
Content of the invention
Invent as solving above-mentioned technical problem, the present invention is by two straight lines of certain intervals, flexibly connection above-mentioned two
The circular arc at straight line two ends is formed with the bar of certain thickness closed section shape, one end of above-mentioned bar has the bar dress for connecting
Join the thick stick of the consistency of thickness of portion, the thickness from the bracing wire department of assembly of connecting stay wire to above-mentioned bar department of assembly and above-mentioned bracing wire department of assembly
Bar is constituted.
The invention has the beneficial effects as follows, the bar of composition adjusting screw and the structure of lever are simpler, the system of each accessory
Make technique also to simplify therewith, facilitating, thus reducing product cost.

Specific embodiment
As shown in Fig. 4 to Fig. 7, embodiments of the invention are by the two straight line L installing at a certain distance, and are connected by flexible
Connect the closed surface that the circular arc line A at the two ends of above-mentioned two straight line L is formed, after extension, form the bar with certain thickness t shape
1；The bar department of assembly 3 that combines with one end of above-mentioned bar 1 and from the bracing wire department of assembly 5 of connecting stay wire to above-mentioned bar department of assembly 3
The thickness lever 7 consistent with the thickness of above-mentioned bracing wire department of assembly 5 is constituted.
Fig. 3 and Fig. 4 of prior art is become apparent from as comparing, that is, in the present invention, above-mentioned bar 1 is in single two dimension
Form and have certain thickness, simple shape, and the unification of the integral thickness of above-mentioned lever 7 in plane, accessory constitutes simply, makes
Processing technology is more easy to be single and saves cost of manufacture.
Here, the single closed curve that above-mentioned bar 1 is two circular arc A formation at above-mentioned two straight line L and its two ends is formed
Two dimensional surface on closed section, towards its thickness t direction extend shape, this shape is not required to traditionally, by two ends
It is processed into semi-spherical shape, but content as be described hereinafter, cost of manufacture can be reduced with extrusion process.
Certainly, the persistency of bar function will be ensured when setting above-mentioned bar 1 thickness t, and can be further by experiment and explanation
It is proven.
The bar department of assembly 3 of above-mentioned lever 7 be encase circular arc A on above-mentioned bar 1 one end arc-shaped slot 9 frame whole in lever 7
Individual thickness, above-mentioned bar 1 is as the above, it is possible to use extrusion process, is formed along above-mentioned closed section pressurization material and can enter
One step reduces cost of manufacture.
In addition, having, on the tappet 11 of other end insertion of above-mentioned bar 1, the vertical groove face 13 guiding above-mentioned bar 1 two sides, make
The bar department of assembly 3 stating bar 1 with above-mentioned lever 7 is combined the ordered state keeping certain afterwards.Also have from above-mentioned on above-mentioned tappet 11
Tappet 11 towards above-mentioned lever 7 be inclined upwardly formation wedge angle θ and have upside groove face 15, make above-mentioned bar 1 along above-mentioned lever 7 upwards
Stating can be same on the upside of the length direction of lever 7.
That is, in the state of the effect of above-mentioned upside groove face 15 is above-mentioned bar 1 insertion tappet 11, it is by above-mentioned lever
The strength of 7 offers passes to above-mentioned tappet 11, relatively can be same to above-mentioned tappet 11.Additionally there is above-mentioned vertical groove face, its
Effect is stablizing with these actions, and limiting above-mentioned bar 1 only can up and down can be with making the bar dress of above-mentioned bar 1 and above-mentioned lever 7
Join portion 3 and keep ordered state.
And the side notch part vertically outwards being run through to side with above-mentioned vertical groove face 13 is also had on above-mentioned tappet 11
17.
The effect of above-mentioned side notch part 17 is, when above-mentioned tappet 11 is gold-plated, so that gold plating liquid is liable to flow out from outside,
And then mitigate the weight of tappet 11.
