10.9. The main transferThe distributor of capacity of the engine on driving wheels: the main transfer
Distinctions in details: power shafts in Mondeo
The general review: power shaft Duratec-VE
The transmission and the main transfer together with differential settle down in the case. Bringing from the engine to a transmission force is transferred through a small and big gear wheel (a gear wheel of the main transfer) to the main transfer. The gear wheel of the main transfer is connected to the differential case. Power shafts finally provide connection with power short circuit between the main transfer and a wheel nave.
The main transfer and power shafts
The main transfer: is together with differential and a mechanical or automatic transmission in one case. In a differential box four settle down entering into gearing with each other конусные gear wheels from which two are connected with power shafts.
Movement on a straight line: forward wheels rotate synchronously with the main transfer. The differential rotates on the same turns, конусные gear wheels in a differential box "are at a stop".
Movement on turn: external in relation to turn the wheel makes больший a way back in comparison with an internal wheel (a difference of frequencies of rotation). If this difference not to compensate, Mondeo strongly would develop also a curve it would be overcome with a turned internal forward wheel. Konusnye gear wheels prevent this effect, in a box of differential they care of necessary alignment: конусная the gear wheel of an external power shaft which rotates faster, has brake influence by means of two intermediate конусных gear wheels on конусную a gear wheel of a power shaft which is correlated with internal area of a curve of turn. The necessary difference of frequencies of rotation will be neutralised by a course difference between two forward wheels.
Force transfer on all wheels (from differential): depending on a combination «the engine – the transmission» Ford establishes in Mondeo on a left-hand side three and on the right party two different power shafts. They differ with the diameters and connection flanges to a transmission. It is impossible to replace external hinges separately, they should be replaced in one complete set with a replaceable power shaft. Depending on a combination "engine-transmission" four different intermediate shaft with the sizes are used similarly.
The hinge of equal angular speeds: such hinges provide comfortable transfer of a twisting moment on driving wheels. As they, differently than карданный the hinge, have less than worn out details are characterised by long duration of existence. From outside transmissions power shafts Mondeo have the hinge - «трипод» (with a tripod-star, running rollers and a tripod-bell), from outside wheels hinges of equal angular speeds (with a spherical star, a separator of the ball-bearing and a spherical cover) are mounted. Hinges of equal angular speeds hardly transfer actions of drives to a steering wheel.
Комели power shafts: rotate from outside wheels in two ball-bearings of a rotary support of the steering mechanism. In contrast шлицевому to connection of the party of a nave of a wheel шлицевое connection from outside transmissions has small torsion which reduces clicking sounds at трогании from a place.

When the power shaft publishes noise Service life of power shafts, naturally, depends also on a way of driving: avoid sprint starts – especially at the deformed wheel disks. Noise which signal about defect presence, according to practice, appear casually. However do not mislead itself – even if such noise have disappeared again for long time – despite it, carefully examine power shafts. And it is symptoms:
Rhythmic shock or кляцкающие sounds which appear during accelerations or a mode of compulsory idling (can change at wheel turns), break "mask" from the defective hinge from outside wheels.
If at movement on a bend your steering wheel «strongly beats to you on hands» it proceeds by all means from defective external hinges of power shafts.
At трогании from a place with the broken wheel disks crash occurrence specifies also in defective power shafts. Remember: the worn out wheel bearing often possesses the same symptom.
