Abstract
The utility model provides an anti-dropping high-wear-resistance brake block and relates to a brake block for an automobile. The anti-dropping high-wear-resistance brake block comprises a steel back, a friction material and a steel tooth. The friction material is pressed into the steel back through a hot pressing method and the steel tooth is embedded into the friction material; the friction material is selected from a high-wear-resistance material doped with ramie; and after the hot pressing is finished, the surface of the friction material of the brake block is treated by plasmas and then is secondarily treated by the low-temperature plasmas. The steel back disclosed by the utility model adopts a box-shaped structure and the steel tooth is arranged on the inner wall of the side edge of the steel back, so that the friction material is prevented from being loosened or dropped; and the surface is subjected to the plasma treatment so that the wear resistance of the brake block is improved.
Description
Technical field
The utility model relates to a kind of automobile and uses brake block, especially a kind of Drop-proof high abrasion-proof brake block.
Background technique
Progress along with China's science and technology; The communications of China, car industry have also had the development of advancing by leaps and bounds; The travelling speed of automobile constantly promotes, and carrying capacity also constantly increases, in order to ensure the safety of automobile running; Must improve the quality of automobile brake sheet, guarantee that the phenomenon of braking failure does not take place automobile brake sheet when driving.At present, the friction material of general automobiles brake block generally directly is bonded on the steel backing, and its shortcoming is that bonding strength is low; Adhesion is little; Automobile is in continuous braking, or under the situation of braking at a high speed, because the brake block temperature rise is too high; The phenomenon that brake block friction material comes off takes place easily, causes brake to lose efficacy.At high temperature simultaneously, brake block friction material heat fade phenomenon is obvious, and the high temperature wear phenomenon is serious, and sharply shorten working life.Raising along with car speed; To the brake block demands for higher performance, promptly require brake block not only to have good braking ability, and require the braking antithesis is not produced irregular wear and damage; Free from environmental pollution, the Drop-proof high abrasion-proof brake block then can satisfy above-mentioned requirements.
The model utility content
The purpose of the utility model is to come off easily or the problem of serious wear in order to overcome in the brake block using process, and a kind of Drop-proof high abrasion-proof brake block that provides.
To achieve these goals, the technological scheme that the utility model adopts is following: a kind of Drop-proof high abrasion-proof brake block comprises steel backing, friction material, steel-tooth, and said steel backing is provided with steel-tooth, is used to strengthen the bonding strength of friction material and steel backing.
Said steel backing adopts box like structure, and the thickness of steel backing is 2.5mm.
Said steel-tooth has 6 groups, is distributed in the steel backing inboard, and the steel-tooth height is 2.5mm, and thickness is 1mm.
The friction material of the utility model adopts mixes a kind of high abrasion resisting material of sisal hemp, and this is basic selection, in addition; In process of production, when treating that brake block is cooled to 35 ℃, utilize plasma to handle; Through after the plasma treatment, re-use low-temperature plasma and carry out secondary treatment, the wear-resisting property on treated brake block surface improves 20%; Experiment is to simulate on the brake disc in high speed to test, and with plasma modification is carried out on the brake block surface, and effect is obvious.The utility model has also adopted special mounting type except that through the above-mentioned processing, is being connected very firmly of brake block friction material and steel backing.
Description of drawings
The structural representation of Fig. 1 the utility model;
Fig. 2 the utility model steel backing structural representation.
1 is steel backing among the figure, and 2 is friction material, and 3 is steel-tooth.
Embodiment
The embodiment of the utility model is following: a kind of Drop-proof high abrasion-proof brake block comprises steel backing 1, friction material 2, steel-tooth 3; Described friction material 2 is pressed in the steel backing 1 through hot-pressing method; Steel-tooth 3 is embedded in the friction material 2, has strengthened the adhesion strength of friction material 2 and steel backing 1 to a great extent, has avoided simple use Bond to carry out when bonding; Because of high temperature or colloid are aging, the phenomenon that the brake block friction material that causes comes off.The material that the utility model friction material 2 is selected for use is the high wear resistance material that is mixed with ramie; After hot pressing is accomplished; When brake block is cooled to 35 ℃; Through plasma brake block friction material 2 surfaces are handled, and then carry out secondary treatment, handle back performance boost about 20% with low-temperature plasma.
The utility model compared with prior art has the following advantages: the steel backing 1 of (1) the utility model adopts box like structure, replaces existing slab construction, can make brake block friction material 2 more firm being fixed on the steel backing.(2) the side inwall of steel backing is provided with steel-tooth 3, and steel-tooth 3 is embedded in the friction material 2, can strengthen the join strength of friction material and steel backing effectively, avoids friction material 2 that loosening or obscission take place.(3) wear resistance on brake block surface has been improved through plasma treatment in the utility model brake block friction material 2 surfaces.
Claims (2)
1. the Drop-proof high abrasion-proof brake block is characterized in that it comprises steel backing (1), friction material (2), steel-tooth (3); Steel backing (1) is provided with steel-tooth (3).
