Abstract
The utility model discloses an upper part brake embedding element, which relates to the field of vehicle braking and solves the problem that a mold of the existing brake embedding element can be easily damaged in the powder metallurgy process production through the structural defects. An installing fixing structure and an engaging structure are arranged on a brake embedding element body, the middle part of the brake embedding element body is provided with a through hole, the installing fixing structure is arranged at the back end of the brake embedding element body, and is an annular groove formed in the brake embedding element body, the back end of the annular groove is a projected baffle ring, a tangent plane preventing the brake embedding element from axially rotating is arranged on the circumference surface of the baffle ring, the engaging structure is two opposite engaging teeth integrally formed on the front end surface of the brake embedding element, the lower edges of the inner end surfaces of the engaging teeth form a certain distance from the edge of the through hole for forming a step of the brake embedding element, the step forms an included angle being 98 to 101 degrees with the located plane of the inner end surface of the engaging teeth, through the optimization on the engaging teeth, the production efficiency can be greatly improved during the powder metallurgy production, the service life of the mold is prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to car brakeing field, is specifically related to the top brake inserts of a kind of engaging tooth through structure optimization.
Background technique
Top brake inserts is the brake member on Vehicular brake device, for guaranteeing the sensitivity of electromagnetic brake, requirement must be pure iron goods, traditional production technology is to process to produce by casting, manufacturing efficiency is low, quality is unstable, in prior art, also there is the top brake inserts of producing by powder metallurgical technique, but, the top brake inserts of normal structure exists engaging tooth inclination angle excessive, and the through hole edge next-door neighbour at the lower edge of engaging tooth interior edge face and brake inserts middle part, top, cause the step at this place too narrow and small, when manufacturing with powder metallurgical technique, excessive engaging tooth inclination angle and too small step make mould fragile when compacting is produced, the working life of mould and the manufacturing efficiency of top brake inserts have been reduced, cost of production and energy consumption have been increased.
Model utility content
The defect existing in order to solve above-mentioned technology, the utility model provides a kind of engaging tooth inclination angle suitable size, and engaging tooth interior edge face lower edge and the through hole edge top that is the determining deviation inserts that brakes.
The utility model is realized the technological scheme that above-mentioned technique effect adopts:
A kind of top brake inserts, comprise brake inserts body, described brake inserts body is provided with mount fixing structure and meshing engagement structure, described brake inserts body middle part is provided with through hole, and described meshing engagement structure is formed in one at the engaging tooth in opposite directions of two on inserts front-end face that brakes, wherein, the interior edge face lower edge of described engaging tooth is away from the edge of through hole, be a platform between the two, form the step of brake inserts, the interior edge face place plane of described step and engaging tooth is the inclination angle of 100～102 °.
Above-mentioned a kind of top brake inserts, the interior edge face place plane of described step and engaging tooth is the inclination angle of 101 °.
Above-mentioned a kind of top brake inserts, two outer rim crest lines of described engaging tooth are 102 ° of angles.
Above-mentioned a kind of top brake inserts, described mount fixing structure is located at the rear end of brake inserts body, for being molded over the annular groove on brake inserts body.
Above-mentioned a kind of top brake inserts, bossed back-up ring is established in described annular groove rear end, and the circumferential surface of described back-up ring is provided with the tangent plane of the inserts axial rotation that prevents from braking.
The beneficial effects of the utility model are: this top brake inserts is not in the situation that reducing product performance, by the engaging tooth of inclination angle suitable size is set, and make the edge of engaging tooth interior edge face lower edge and engaging tooth middle part through hole be a determining deviation, form the step of larger width, make it when producing with powder metallurgical technique, significantly improved the manufacturing efficiency of top brake inserts, reduced energy consumption, improve the working life of mould, cut down cost of production.

Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of top brake inserts, comprise brake inserts body 1, brake inserts body 1 is provided with mount fixing structure and meshing engagement structure, its middle part is provided with through hole 2, meshing engagement structure is formed in one at the engaging tooth 4 in opposite directions of two on inserts front-end face that brakes, wherein, as improvement of the present utility model, the lower edge of the interior edge face 41 of engaging tooth 4 and the marginating compartment certain distance of through hole 2, be a platform between the two, form the step 6 of brake inserts, this step 6 is the inclination angle of 100～102 ° with the interior edge face 41 place planes of engaging tooth 4.As preferred embodiment of the present utility model, this inclination angle size is set to 101 °, and two outer rim crest lines 42 of engaging tooth 4 are 102 ° of angles.
During enforcement, mount fixing structure is located at the rear end of brake inserts body 1, for being molded over the annular groove 3 on brake inserts body 1.Bossed back-up ring 5 is established in these annular groove 3 rear ends, and the circumferential surface of back-up ring 5 is provided with the tangent plane 51 of the inserts axial rotation that prevents from braking.When mounted, annular groove 3 can be fastened in corresponding inserts, and two on back-up ring 5 in opposite directions tangent plane 51 can prevent that top brake inserts from axial rotation occurring in use.
This top brake inserts is not in the situation that reducing product performance, by the engaging tooth 4 of inclination angle suitable size is set, and make the lower edge of interior edge face 41 of engaging tooth 4 and the edge of the through hole 2 at engaging tooth 4 middle parts be a determining deviation, form the step of larger width, make it when producing with powder metallurgical technique, significantly improved the manufacturing efficiency of top brake inserts, reduced energy consumption, improve the working life of mould, cut down cost of production.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection domain that the utility model requires is defined by appending claims and equivalent thereof.
