Abstract
The invention discloses a kind of heavy mechanical brake pad, belong to mechanical braking sytem field, comprise and being made up of following component: copper powder, barium sulphate, red copper fiber, modified resin, barite, nitrile butadiene rubber, Frication powder and three vanadium oxides.Increased wear resistance and the hardness of brake block by interpolation copper powder and three vanadium oxides, increased the friction factor of brake block by interpolation barium sulphate and barite, added the adhesiveness of brake block by red copper fiber, modified resin and nitrile butadiene rubber.It is large that the brake block of manufacture of the present invention meets hardness, and friction factor is high, good braking effect, and brake block heat resistance is strong, and the coefficient of stability is strong, and wear resistance is strong and to features such as the wear intensity of brake disc are little.
Description
Technical field
The present invention relates to mechanical braking technical field, particularly relate to a kind of heavy mechanical brake pad.
Background technique
Braking system is one of most important safety system on automobile, and brake block has suffered parts important in braking system, it can directly have influence on the reliability of haveing suffered braking system, braking system defines friction pair by brake block and the mutual friction of brake disc phase, produce braking moment, be heat energy by the kinetic transformation of automobile, temperature during braking can rise to 300 ~ 400 DEG C.
Conventional brake block is divided into: 1, asbestos type, because asbestos fiber has high strength and resistant to elevated temperatures feature, therefore meet the requirement of brake block and clutch disk, there is the tensile energy of fiber and the hardness of advanced metal material and wear resistance simultaneously, but the heat resistanceheat resistant poor performance of this brake block; 2, semipermanent mold, main adopts coarse Steel Wool as reinforced fibers and the large mixture of important friction factor, and major advantage is adapt to normally work at relatively high temperatures, but noise too greatly, and larger to the wear rate of brake disc; 3, without asbestos organic type, mainly use glass fibre, aromatic polyester fiber and other fibers as reinforcement material, its performance depends primarily on type and other mixture of fiber, and advantage is that shortcoming is that wear resistance and heat resistance are not strong without the ash fouling that falls, feature that noise is little.
Summary of the invention
For above technical problem, the invention provides a kind of heavy mechanical brake pad, by the improvement on raw material, providing one, to meet friction factor high, good braking effect, brake block heat resistance is strong, and the coefficient of stability is strong, the brake block that wear resistance is strong and little to the wear intensity of brake disc, especially can play good braking ability on the braking effect of heavy machinery.
The present invention is achieved by the following technical programs:
A kind of heavy mechanical brake pad, comprises and being made up of following component: copper powder, barium sulphate, red copper fiber, modified resin, barite, nitrile butadiene rubber, Frication powder and three vanadium oxides.
Further, this brake block is made up of the raw material of following percentage composition: copper powder 20 ~ 40, barium sulphate 10 ~ 20, red copper fiber 10 ~ 20, modified resin 10 ~ 20, barite 5 ~ 15, nitrile butadiene rubber 5 ~ 15, Frication powder 3 ~ 10 and three vanadium oxides 0.1 ~ 2.
Further, this brake block is made up of the raw material of following percentage composition: copper powder 25 ~ 35, barium sulphate 12 ~ 18, red copper fiber 12 ~ 18, modified resin 12 ~ 18, barite 8 ~ 12, nitrile butadiene rubber 6 ~ 10, Frication powder 5 ~ 8 and three vanadium oxides 0.1 ~ 1.
Further, this brake block is made up of the raw material of following percentage composition: copper powder 30, barium sulphate 15, red copper fiber 15, modified resin 15, barite 10, nitrile butadiene rubber 8, Frication powder 6.5 and three vanadium oxides 0.5.
Beneficial effect of the present invention is: the wear resistance and the hardness that are increased brake block by interpolation copper powder and three vanadium oxides, increased the friction factor of brake block by interpolation barium sulphate and barite, added the adhesiveness of brake block by red copper fiber, modified resin and nitrile butadiene rubber.It is large that the brake block of manufacture of the present invention meets hardness, and friction factor is high, good braking effect, and brake block heat resistance is strong, and the coefficient of stability is strong, and wear resistance is strong and to features such as the wear intensity of brake disc are little.
