Abstract
A drum break lining comprises arc lining, whereon the inner side of the arc linking cut flutes in net for cooling. The flutes make the lining smaller therefore save raw materials up to 5%-10%. The flutes allow air go through therefore cool down the lining and prevent low friction performance caused by over heat and avoid wearing of the lining.
Description
Technical field
The present invention relates to a kind of break accessory, especially a kind of open slotting drum lining of vehicle brake.
Background technique
Present brake facing does not have recessing on the arc surface within it, so consumable material is many, the cost of production height.In addition, this brake facing heat dispersion is poor, and working life is short.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of inner arc surface to have the open slotting drum lining of vehicle brake of heat radiation groove.
The present invention solves the technological scheme that its technical problem adopts: this open slotting drum lining of vehicle brake, comprise the liner main body of circular arc, and this liner main body has the heat radiation groove on the arc surface within it.
The present invention can be further perfect by following manner: inner arc surface has horizontal, vertical two kinds of heat radiation grooves, and two kinds of heat radiation groove cross-distribution are latticed arrangement.
The effect that the present invention is useful is: 1). after mold pressing, because the liner inner arc surface forms groove, small product size is dwindled, can save the materials of 5%-10% thus, under the situation that the automotive friction material appreciates significantly, the cost of raw material ratio of producing the automotive brake liner has reached 65%, after the conversion, can reduce total production cost at least more than 3%.By 100,000 tons of calculating of year consumption of the present automotive brake liner of China, can save 5000 tons automotive friction material resources at least, its worth up to is more than 3,000 ten thousand yuan.2). after the brake facing inner arc surface forms groove, the actual passage that has also just formed air flows, when automobile traveling, the air flows that the wheel rolling rotation produces can be passed through groove smoothly, reduce the temperature of brake facing, prevent because the situation of the too high reduction frictional behaviour of temperature, also can reduce because temperature is too high and cause brake facing self accelerated wear test, guarantee traffic safety, reduce the operation cost of automobile.Through the entrucking of this improved products is used, prove that wear rate decreases, can prolong about 10% working life.

Description of reference numerals: liner main body 1, inner arc surface 2, rivet hole 3, groove 4.
Embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing: this open slotting drum lining of vehicle brake, comprise the liner main body 1 of circular arc, and liner main body 1 has rivet hole 3.This liner main body 1 has heat radiation groove 4 on the arc surface 2 within it.Inner arc surface 2 has 4, two kinds of heat radiations of horizontal, vertical two kinds of heat radiation grooves groove, 4 cross-distribution, is latticed arrangement.
The present invention is the improvement design of carrying out on the basis that does not influence various drum lining of vehicle brake working principle.In manufacturing process, be applicable to the prescription of the various components of automotive friction material, do not need to change process parameters such as pressure in technological process and the manufacturing process thereof, temperature yet, do not need newly-increased machinery equipment.Be with the difference of original product: according to the size of product, thickness and each rivet hole 3 relative position degree and aperture thereof, determine groove 4 width and the degree of depth of inner arc surface 2, by machining is carried out on compacting tool set multilayer film pressing plate external arc surface, make molded sheets on outer arced surface, form groove, make it the processing object inner arc surface and after mold pressing, also form groove, the position that needs boring to rivet also forms boss, liner after guaranteeing to complete has enough riveted joint faces to fit tightly on the brake shoe arc shaped surface, make it enough frictional force and guarantee the stability of automotive brake liner, thereby the optimization of having finished drum lining of vehicle brake improves.
Here to making the product inner arc surface be the degree of depth of groove after the molded sheets machined grooves and the requirement of width is illustrated respectively:
1, indeformable for guaranteeing the product after the mold pressing completion, generally do not consider machined grooves 4 when product thickness 10mm is following.
2, when product thickness 10mm-14.5mm, groove 4 degree of depth are 2.5mm, and when product thickness 14.5mm was above, groove 4 degree of depth were 4mm.
3, groove 4 width are by the size decision of riveted joint boss face, and the size of riveted joint boss face is by the size decision of rivet hole 3.Generally speaking, rivet hole 3 big bore edges and boss face edge minimum range should guarantee 15mm; In unit area, position, hole more relatively (the hole bit density is relatively large), aperture relatively hour, the distance at rivet hole 3 big bore edges and boss face edge can be dwindled, but minimum range must not be less than 10mm.
The present invention under the condition that does not change brake facing fundamental function-friction performance (frictional behaviour and wear rate), has remarkable economy and practicability through after improveing.
In sum, this programme investment is little, and only need slot to process to the pressing plate of compacting tool set gets final product, both easy to implement, have the economic benefit that can quantize again, the ratio of its input and output (ratio of the expense of clamping cap machined grooves and the expense that saves material) can be up to 1: 10.
