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.

1-  Steering angle.
2-  Brake operation.
3-  Steering angle and speed.
4-  Fast raise/lower switch position.
 6 drive discs and 6 driven discs
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.

befor you can read  part 1 -2

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

Self Lubrication Gearbox – Fully self contained system, Multiplate clutch electro-hydraulically engaged via a proportional solenoid valve allowing a modulated starting of the 1000 rpm PTO. The PTO is either “on” or “off” there is no modulation. Drive supplied from the engine crankshaft through duplex chain drive and sprockets.
1. Input from engine crankshaft via Duplex chain & sprockets
2. Piston Brake

2.Clutch release bearing
3.Spring
4.Piston
5.Diaphragm spring
Disengaged
Solenoid valve de-energised allowing the oil to return to the reservoir.
The spring (3) pushes the piston (4) out of the housing and pushes the clutch release bearing (2) into the PTO clutch diaphragm spring (5).
Pressure is applied to the diaphragm spring (5)  releasing the force acting on the clutch pressure plate.
The springs in between the friction discs and steel plates (1) expand, allowing the clutch hub to rotate freely within the clutch housing.
Engaged
Solenoid valve is energised, applying low pressure oil to the piston (4).
Low pressure oil acting against the piston (4), overcomes the piston spring (3), retracting the piston (4) into the housing, releasing the clutch release bearing (2) from the force of the diaphragm spring (5).
The diaphragm spring (5), compresses the springs in between the friction discs and steel plates (1), clamping the friction discs and steel plates (1) together, locking the clutch hub and the clutch housing together.

1 - Oil return pipe
2 - Oil pressure supply pipe
NOTE: This block must be fitted when the Front PTO option is requested, even if the tractor has not got front brakes.

Supersteer in new tractor

As the hubs on the axle turn up to 45º, the axle simultaneously 
articulates up to 20º
giving a total turn angle of 65º. This means the operator can 
 turn tighter and
more quickly at the end of the field.
This results in smaller headlands leading to Less compaction 
and greater productivity.
The SuperSteer system ulitises two large diameter steering rams 
 and two tie rods
which connect the axle hub to the tractor chassis. As the steering ram extends, the tie rod linking the front axle to  the tractor
causes the axle to progressively articulate in the direction of wheel turn.



SuperSteer Axle Components
1. Steering Cylinder
2. Pin
3. Tie Rod
4. Pin
5. Bushing
6. Spacer
7. Support
8. Tube
