عايز حد خبره فى الترصيص يفيدنى

[عصام غنايم]

انا مليش في الكلام ده أوي بس ممكن يكون في مشكلة في المساعدين او السوست ولو حاطط علايات ولاحاجة والله أعلم...

لا انا مش حاطط علايات ولا المساعدين فيها حاجه العربيه لسه 2008

[عصام غنايم]

من وجهة نظرى كوتش 15 دا كتير على لانوس و عريض جداً و كمان بيكون ليه تاثير سلبى على العفشه والمساعدين

اولا 15 مش كتير ابدا عل الانوس وادخل على اى موقع تعديلات هتلاقى الانوس بتشيل لحد 17 كمان
ومش مؤذى للعفشه الموضوع كله 2 سم عرض زياده فى الفرده ولو جبت كاوتش طرى وجنط رقم الاوفست بتاعه مظبوط هيبقى كله تمام

كمان يا صاحبي الكوتش 15 غالى جداً 14 كان مكفايه على العربيه على شان ميبقاش بارز برا العربيه

فرق السعر بين ال15 وال14 تقريبا 30 جنيه للفرده يعنى مش توفير ومش هيغرق

البروز والدخول للجنط مش بيحكمه عرض الجنط او مقاسه لالالالالا

اللى بيحكم الدخول والخروج رقم الاوفست الخاص بالجنط et

على العموم ازواق

المسأله مش اذواق او مناظر وخلاص
لا
فرق الثبات والتحكم يستاهل المصروف والتعب
كفايه انك تعرف ان تغيير الجنوط والكاوتش ابسط واقوى تعديل بالنسبه للثبات

لو جربت هتحس من كتر التغيير انك غيرت العربيه اجمالا

واتمنى لك الفائده

وانا ايضا ولك جزيل الشكر على اهتمامك

[عصام غنايم]

النقط دى المفروض انهاتبقى ناحية البلف عشان بعد ما ترصص و الفردة تتخرم و تفكها تركبها على نفس الوضع باستخدام النقطة كا دليل عشان الفردة متحتاجش ترصيص تانى

لا
انا مش مقتنع يا ابو يوسف
لو الموضوع علشان البلف كانو حطوا نقطه واحده وبلون واحد انما نفس الفرده يحطوا نقطه صفراء واخرى حمراء

انا اظن ان الموضوع له علاقه بمكان الرصاص على الجنط

انا اللى بشوفة دايما بيبقى دايرة حمرا... معرفش قصة العلامات التانية دى ايه

و لو كلامك صح حيبقى فيه سؤال بيطرح نفسة بشدة.... ازاى تحط علامات ترصيص على الكاوتش من غير جنط؟؟؟

مهو الجنط شخصيا بيفرق فى الترصيص بالتالى مش منطقى خالص انى اعمل علامة توزن الكاوتش بدون عمل حساب الجنط... دا طبعا غير ان العلامة متوضحش وزن الرصاص المطلوب بفرض انها لترصيص الكاوتش

والله يا ابو يوسف انا مش متأكد من الموضوع اوى
بس
انا عملت حاجه هبله شويه
خليت الراجل يحط الجنط على ماكينة الترصيص بدون كاوتش اول وعلمت على مكان الرصاص وركبت الكاوتش العلامه الحمراء على مكان الرصاص وبعدين رصصت الجنوط مأخدتش رصاص كتير

انا زمان كنت قريت موضوع على موقع اجنبى بيتكلم على العلامتين دول بس مش فاكر الكلام اوى بس اجمالا ان مصنعى الكاوتش بيعلموا على اماكن الثقل فى الفرده
الكلام بالظبط ايه مش فاكر
قلبت الدنيا تدوير على النت علشان الاقى الموضوع ده تانى مش لاقيه
بس الموقع ده كان بيتكلم على انواع العفشه والاختلاف بينها يمكن حد يفتكره او يلاقيه ويفيدنا

دة اقتباس من سايت بيتكلم عن الحوار دة:

What Are These Red and Yellow Dots On My Tires?


[justify]
The dots actually serve a very important purpose in ensuring accurate installation. The red and yellow dots help installers find a tire’s high spot, low spot and light point for consistent balancing.

According to Bridgestone, “The difference between the high and the low is called radial runout. Using sophisticated computer analysis, engineers have found that a graph of the force variations looks a bit like a wave, as does a graph of the runout variations.

By simplifying the graphs to what is called their “first harmonic,” it’s possible to find the place on the tire where, on average, the force variation is greatest. That’s where the first harmonic curve hits its high point. And, it turns out that the first harmonic high point for the radial runout coincides pretty well with the first harmonic high point for radial force variation.

Now wheels, especially steel wheels, tend to have the same kind of high and low spots as tires. In fact, many steel wheels are marked with a dimple that indicates their low spot. So, if you could match the high point on the tire to the low point on the wheel, these forces would, to some extent at least, cancel each other, and you’d expect to get a smoother ride and maybe improved wear.

Some original equipment manufacturers are doing this kind of match mounting when they mount tires and wheels on new trucks. The tire is marked with a red dot at the high point, and this is matched with the low point dimple on steel wheels. On steel wheels without a low point dimple, and on aluminum wheels, the red dot is matched to the valve stem.”

A yellow dot indicates the light balance point on the tire. In order to minimize the amount of weight needed to balance a tire and wheel assembly, match the light balance point to the wheels heavy balance point, which is normally located at the valve stem.

In a situation where a tire has both a red and yellow dot, the red dot takes precedence and should be mounted to the wheel low point dimple or valve stem.

The Tire Doctor Responds:
Those spots before your eyes can mean many different things. Some of those dots can even help you minimize ride disturbances and irregular wear.





What Do These Marks Stand For?
In a perfect world, you'd have perfectly round, perfectly balanced tires, mounted on perfectly round, perfectly balanced wheels, attached to perfectly straight, perfectly true-running axles.
But in the real world, nothing is perfect. No matter how hard manufacturers work to eliminate them, there are always variations in tires, wheels, hubs, bolts, axles, and every other part of a wheel end assembly.
And even if they come out of the factory in near-perfect condition, wear, damage, improper installation or poor maintenance can negate the manufacturer's efforts.
These variations can create what are called radial and lateral force fluctuations. Those are fancy words, but the result of either one can be ride disturbance, rapid wear, irregular wear — or all three.
Careful tire mounting using these marks can help you minimize these problems. Some Of My Tires Have Red Dots. What Are They For?
When a tire spins, the amount of force it exerts against the road varies. In severe cases, the result can be a rough ride and wear problems. One reason the force can vary may be that the tire isn't perfectly round. It has "high" spots and "low" spots. (There are also lots of other reasons, which we'll explore in future issues of Real Answers.)
The difference between the high and the low is called radial runout. Using sophisticated computer analysis, Bridgestone engineers have found that a graph of the force variations looks a bit like a wave, as does a graph of the runout variations.
By simplifying the graphs to what is called their "first harmonic," it's possible to find the place on the tire where, on average, the force variation is greatest. That's where the first harmonic curve hits its high point.
And, it turns out that the first harmonic high point for the radial runout coincides pretty well with the first harmonic high point for radial force variation.
Now, wheels, especially steel wheels, tend to have the same kind of high and low spots as tires. In fact, many steel wheels are marked with a dimple that indicates their low spot.
So, if you could match the high point on the tire to the low point on the wheel, these forces would, to some extent at least, cancel each other, and you'd expect to get a smoother ride and maybe improved wear.
Some original equipment manufacturers are doing this kind of match mounting when they mount tires and wheels on new trucks. The tire is marked with a red dot at the high point, and this is matched with the low point dimple on steel wheels. On steel wheels without a low point dimple, and on aluminum wheels, the red dot is matched to the valve stem.
For a slight improvement in uniformity on steering tires, with hub-mount wheels, you can torque wheel nuts with the red dot at the "12 o'clock" position.
Carefully tighten one nut with a hand wrench before using the air wrench. Be sure the air wrench does not reposition the wheel.








What Are The Yellow Dots For?
Just as it's very hard to make a tire or wheel that's perfectly round, it is also very difficult to make tires and wheels that are perfectly in balance.
You can help minimize the amount of weight needed to balance a tire and wheel assembly by mounting the tire so that its light balance point is matched up with the wheel's heavy balance point.
All new Bridgestone truck and bus radials are factory- marked with a yellow dot at the light balance point. Generally, the heavy balance point of a wheel is at the location of the valve stem. This is true regardless of whether the wheel is steel or aluminum.
For best initial balance, match yellow dots to valve stems. Which Dot Takes Precedence?
If a Bridgestone tire you're mounting has both red and yellow dots, the red dot has priority. Match it to the wheel low point dimple or valve stem. Ignore the yellow dot. Remember, "red rules."
Do I Have To Do Anything Special On Duals?
On dual assemblies, the best idea is to "clock" the two wheels so that their valve stems are 180 degrees apart. There are several advantages to this:
1. It makes air pressure maintenance easier.
2. Match-mounting tires and wheels puts the high points or balance points opposite each other, which helps counteract remaining imbalance or force variations.
What About Marks And Dots Of Other Colors?
On Bridgestone radials, only red or yellow dots are used in match-mounting. Ignore any other colors.
Does Every Tire Manufacturer Use The Same Marks?
Unfortunately, no. Some manufacturers do not mark their tires at all, and some use different colors. If you're not using Bridgestone radials, you'll need to consult your tire supplier for more information.

عملت ايه يا عصام في موضوع الجنوط

من الواضح من الكلام انك تظبط العلامة الحمراء قدام العلامة المدورة اللي في الجنط او فتحة البلف وتظبط الجنطين اللي قدام بعض 180 درجة بين العلامتين او البلفين

وصلت لايه وطلعت المشكلة في ايه؟

[عصام غنايم]

بالنسبه لموضوع الحدفه يمين بعد تركيب الجنوط فكانت من ظبط هواء الكاوتش وحليتها بشراء مقاس هواء خاص بى

بالنسبهل للجنوط اللى بتنزلنا مفيهاش علامه مقابله لعلامة الترصيص الحمراء فى الكاوتش

فالانسب انك توازى العلامه الحمراء فى الكاوتش مع فتحتة البلف فى الجنط

بالنسبه للترصيص فالترصيص اللصق جوه وبره انسب حل للجنوط الاسبور والمهم المكنه بتاعت الترصيص

عندنا فى دمياط واحد عنده مكنه كومبيوتر ممتازه بس هوا تنك اوى وانا مبحبش التعامل معاه

لو حد يعرف مركز ترصيص فى دمياط او بورسعيد او المنصوره يا ريت يقولى عليه بس يكون مجربه فى جنوط اسبور وظبط معاه

واكون شاكر
