2021-08-06Hangzhou HLK Advanced Materials Co., Ltd.: differences and selection of motorcycle brake pads (II)
C. Relationship between friction coefficient and working temperature
In addition to the friction coefficient, the effective operating temperature of the brake pad is also very important. The various metals and compounds used to make brake pads will only be effective at a certain temperature. To widen the effective working temperature of the brake pad, the manufacturer adds different metals or other synthetic materials to the brake pad formula, and uses high temperature and high pressure to integrate various materials into a synthetic material. When designing the characteristics of brake pads, manufacturers should consider the other four elements in addition to the friction coefficient and operating temperature. Therefore, there is no brake pad compound in the world that can get full marks in the range of six items. Also, in the real world, no motorcycle can contain all the characteristics, so manufacturers prepare corresponding products according to the needs of different motorcycles< br /> Differences and selection of motorcycle brake pads
There are great differences in the force used by motorcycles, high-performance Road sports cars and racing cars in biaohuaxing street. It is also inappropriate to use racing pads for street cars or brake pads for street cars. The characteristics of street and racing brake pads lie in the temperature difference during braking. The car needs to constantly exert 100% braking power at extremely high speed, and the range from kinetic energy to thermal energy is unimaginable for street cars. For ordinary street braking systems, if the brakes are applied continuously for about ten times, the brake pads will begin to "heat decay". Therefore, the brake skin for racing must still maintain a high-efficiency friction coefficient at high temperature, so the friction coefficient will be poor at normal temperature< br /> The performance of the brake pads used in racing cars before 250 ℃ is much worse than that used in sports cars. However, when the temperature is between 300 and 500 degrees, the friction coefficient of the force skin for racing cars is much better than that for sports cars
D. Is the friction coefficient important, or is the handling important? In the real world, there are more than three types of brake pads? It should also be noted that when the brake pad operation is involved, the interference to the control should be minimized, that is, the feel should be gradual in order to facilitate the control. Brake pads with high friction coefficient usually have great interference and are unfavorable for handling. Therefore, for people who pay attention to forced hand control or need to compete in wetlands, they will choose brake pads with low friction coefficient, such as racing specification 1 shown in the above figure to increase hand control< br /> Hangzhou hanleke New Material Technology Co., Ltd. mainly produces special friction materials and components such as lawn mower and chain saw gasoline engine clutch, motorcycle clutch friction plate, motorcycle brake shoe block and disc brake plate, construction machinery brake plate, motor friction plate, electric hoist and so on.

2021-08-05Hangzhou HLK Advanced Materials Co., Ltd.: differences and selection of motorcycle brake pads (I)
The most cost you can't save by riding a motorcycle is the replacement of tires and the maintenance of brake pads of the brake system. What shock absorber, titanium ruler and exhaust pipe are just icing on the cake. If you don't replace it when it's due, you can drive a little slower at best. However, tires and braking systems are important factors related to life safety
A. How to evaluate the quality of brake pads? The quality of brake pads (brake pads) is not simply selected for racing cars, it is better to be so simple. We want to see: 1) what is the friction coefficient of the brake pad? 2) How wide is the effective operating temperature of the brake pad? 3) How fast does the brake pad wear out? 4) How loud is the noise when braking? 5) How much force powder does the force pad release when braking? 6) Is the friction provided by the brake pads linear? Easy to master? The higher the friction coefficient, the higher the work efficiency of the brake pad. However, choosing brake pads for your car does not mean that the higher it is, the better it suits your needs. The weight and speed of different vehicles are different. For vehicles with low speed and light body, the force skin with high friction coefficient will destroy the handling and affect the driving feeling& nbsp;< br />
B. What is the coefficient of friction? The friction coefficient (U) is a quantitative simplification to describe the friction resistance. One of the simplest calculation methods is to divide the frictional resistance (FR) by the force (FN) required to counteract the friction and successfully pull the animal part. The friction coefficient is calculated as u = FR / FN. Another measurement method is to measure the gravity, that is, the weight (W) of the object: u = FR / W. For example, in the left figure, the weight of the book is w, divided by the force required to pull the book on the desktop, and the weight measured by the slingshot pound is the friction coefficient between the book and the desktop
Based on different conditions, the conditions constituting the friction resistance (FR) and the force (FN) breaking the friction resistance are different, so the friction coefficient is divided into at least four different versions. Among them, the common ones are static coefficient of friction and dynamic coefficient of friction, and the ones applied to motorcycle braking system are, of course, dynamic coefficient of friction& nbsp;< br />

2020-08-31Hualong friction materials Co., Ltd. participated in the first training of G8D in China
Globally harmonized 8D method (G8D) was evolved by Ford in 1995 on the basis of the past 8D to avoid the differences between different regions and countries and promote the effective solution of problems. As we usually know, 8D is only a part of G8D, and there has not been any public training on this content in China before. From August 28 to 30, tianyiyuan training center held the first domestic G8D public class, which was registered by China Quality Association Mr. Cao Shugen, the black belt of GMA, is the keynote speaker. Hualong friction materials company attached great importance to it and sent 5 staff from engineering technology department, quality department and production department to Ningbo to participate in this training.
The difference between G8D and 8D is that the former is detailed, while the latter is rough everywhere. G8D has incomparable advantages over 8D in improving customer satisfaction, improving internal communication, solving problems and responding to customer concerns, and eliminating problems from products and processes. Hualong 5 people studied carefully, and Su Gongzuo wrote the only summary and suggestions among all the training teams:
Company welfare, participated in the training of global unified 8D method, and was given a lecture by Cao Shugen, a black belt of Six Sigma registered by China Quality Association. This G8D content has never had an open class in China before. The training is 16 class hours in total, and half of it has been carried out today.
All participants of Hualong friction materials company understood that the difference between G8D and 8D is that the former is detailed and detailed, while the latter is rough and ubiquitous. G8D has incomparable advantages over 8D in improving customer satisfaction, improving internal communication, solving problems and responding to customer concerns, and eliminating problems from products and processes.
To name a few.
In the past 8D, D2's problem description only described who, what, when, where, how long, etc., while G8D required to distinguish between symptoms and problems, statements and descriptions. Only by making clear the symptoms and problems, statements and descriptions can we fundamentally find the direction to deal with the problems.
There are only temporary measures and permanent measures in 8D, while G8D divides the measures to solve the problem into emergency measures and temporary measures
Construction and permanent measures. Some people asked the difference between emergency and temporary measures. Mr. Cao answered: emergency measures are for symptoms and temporary measures are for problems; Emergency measures must be completed within 24 hours, and temporary measures within three days; Emergency measures are limited to sorting, isolation, shutdown and other means. Temporary measures can be rework, repair and other methods based on certain survey data.
What makes us feel a lot is Mr. Cao's attention to basic concepts. Problems and symptoms, emergency measures and temporary measures have been mentioned above. Let's talk about a small and representative example: what is a factor? What is the reason? Mr. Cao explained the connotation and extension of these two concepts with a large number of specific examples to let the students understand that the connotation of factors is larger than the reason, the extension is smaller than the reason, the reason includes factors, and various factors should be found out from the reasons.
Maybe it's because of the tense class hours. Mr. Cao only focuses on pouring dry goods and ignores the simple and easy, relaxed humor and students' acceptance ability. Maybe some people (including me) don't understand it for a moment.
G8D is a problem-solving method of induction and deduction. The minimum requirement is to adhere to common sense and at least logical thinking. But the Chinese people all step into the society and go to work after anti common sense and anti logic education. For example, what we have accepted since childhood is the anti common sense and anti logical thinking such as "there is no water in the river and the river is dry". Mr. Cao might as well start with revealing the anti science of this proposition, and first educate everyone to get out of the anti causal misunderstanding that there is no brick without wall and no thread woven into cloth without cloth. After getting out of this misunderstanding, it may be easier to learn G8D. My opinion is for reference only.
