Differentials part p3
Limited Slip Differential
This differential lock device is totally
automatic. It does not require any type of manual
operation and significantly reduces (but does not
completely eliminate) wheel
slipping.
The difference in speed, between the sun
gears and the differential casing when a
wheel
begins to slip as a result of grip loss, is impeded by
clutch assemblies that are
compressed by axial thrusts from
the bevel drive torque transmitted to the sun gears
by means
of the teeth on the two planet gears.

Dog
Clutch Differential Lock:
With
diff lock disengaged no oil pressure is supplied, spring keeps the dog clutch
teeth apart,
oil can return to sump.
When
the diff lock switch is activated the solenoid valve opens supplying low
pressure circuit
oil
to the piston, overcoming the spring locking the
differential.
Multi-Plate
Differential Lock:
•
Actuated from Low Pressure Circuit Oil - via solenoid valve.
•
Terra lock control for automatic dis-engage and re-engagement.

2- Brake operation.
3- Steering angle and speed.
4- Fast raise/lower switch position.

Assemble
side gears, pivot pins and retaining pins.
Place
the side gear (3) complete with a test shim (2) on tool no. 293986 (1).
Assemble
the side gear and attached tool no. 293986 on the differential casing, place
the crown wheel above it and fix the crown wheel with three bolts (4). Turn the
assembly to settle.
Place
a dial test indicator gauge with the stylus on the tool screw (5), press the
tool
and set gauge to zero.
Pull
the tool (6) upwards and read the travel (H) on the gauge.

Differentials part 2
الجهاز الفرقى الجزء 2
In
this example we can now see a complete differential and crownwheel. The bevel pinions (sun gears) are mounted
within the differential cage. Power is transmitted from the crownwheel
through the differential cage which in turn rotates the bevel pinions and half shafts as a complete fixed unit when
driving in a straight line.
As
the vehicle travels round a bend the bevel pinions are free to spin on their
axes to allow for the individual half shafts to decrease and increase in speed.
As the half shaft driving the inner wheel reduces in speed the outer wheel half
shaft will increase in speed as the distance required to travel round the bend
will be higher.
The Crownwheel will allways rotate at an average of the two half
shaft speeds

Differential
Operation
If
both drive shafts are travelling at the same speed the bevel pinions will not
be turning on their axes. The bevel pinions will simply rotate with the bevel
gears. This can be best explained by imagining the bevel gears an bevel pinons have
been welded together
If
one half shaft is stopped the bevel pinions will start turning on their axes
and begin orbiting around the stationary bevel gear at the same time providing
drive out through the other half shaft.
Although
necessary for cornering differentials have a major drawback within agricultural
applications in that should one wheel begin to spin freely then the remaining
drive wheel will stop rotating (as shown above) and the vehicle becomes
stationary. For this reason it is
necessary to have a differential that limits the amount of wheel slip. Such
differentials are referred to as limited slip differentials.
An
alternative solution commonly found within agricultural machines is to
introduce a locking mechanism that will lock the complete differential

ينقسم الدسك إلى :
1- شاسية يحمل عليه أقراص الحرث والتنعيم والعجل وخراطيم الهيدروليك والمنظم الهيدروليكى والشاسية ثقيل جدا لضمان عمق حرث جيد بعمق جيد للتربة ويحتاج الدسك الذى فى الصورة لجرار لا يقل قدرته عن 225 حصان حيث يحتاج الدسك لقدرة شد عالية بسبب وزنه وعمق الحرث أى مقاومة التربة
2- أقراص حرث خلفية وهى دائرية مقعرة ملساء lحادة جدا وثقيلة كى تتعمق فى التربة ونصف قطرها يختلف حسب الدسك من 25 سم إلى 35 إى 45 والمنتشر 35 و25 سم وهى ثقيلة
3- أقراص التنعيم وهى فى الأمام وهى ملساء وبنفس قطر أقراص الحرث الأمامية ولكنها مشرشرة فى أخر القرص للتنعيم وقطع أى أجزاء محصول متبقية وتنعيم التربة والأحجار الصغيرة أما الكبيرة فتؤدى لمشاكل فى الدسك وصيانة عالية وإصلاح وقطع غيار مكلفة جدا
3- خراطيم هيدروليك لنقل الحركة من الجرار إلى محاور الدسك لرفع الأقراص كما فى الصور وتنزيلها كما يضبط عمق الحرث بوجود بساتم لرفع وتنزيل شاسية الدسك نفسه وتشترك هذه الخراطيم فى بداية الدسك ب
5 -منظم وهو عبارة عن مشترك لتوزيع الزيت على بساتم المحاور جميعها
6- قاطرة للشبك فى الجرار يمكن تطويلها وتقصيرها فى بعض الأنواع
7- الكاوتش ومعروف وظيفتة وهو من النوع المخطط كما فى الصورة
8- محاور مركب عليها أقراص الحرث والتنعيم وفى بدايتها ونههايتها صامولة كبيرة 46 أو 50 لإحكام ربط الأقراص ومركب عليها
9- أقماع لحفظ لحبك محاور الأقراص وإحكام ربطها بين كل قرص والأخر
10- البلى : يرتكز عليها الأقراص لتعطيها الحركة الدائرية وهى من نوع البلى ذات الكرسى بومبيه وبها مشاحم للتشحيم ولابد من تشحيمها بشحم جيد كل 50 أو مائة فدان حرث
