5.9. Drives of forward wheels

Fig. 5.9. A drive of a forward wheel: 1 – the case of the internal hinge; 2 – a clamp; 3 – a collar of fastening of a cover; 4 – a shaft of a drive of a wheel; 5 – a protective casing of a cover; 6 – a protective cover; 7 – a persistent ring of a holder; 8 – a separator; 9 – a collar; 10 – a ball; 11 – a holder of the external hinge; 12 – a lock ring; 13 – the case of the external hinge; 14 – a collar of fastening of a casing

The twisting moment is transferred to forward wheels from a reducer of the forward bridge through the right and left drives. Both drives are identical on a design. Each drive consists of a shaft 4 (rice 5.9) and two hinges of the equal angular speeds established on it шлицевых the ends.

The case of the internal hinge 1 is connected to a semiaxial gear wheel of a reducer of the forward bridge. The case of the external hinge 13 is connected to a nave of a forward wheel. The holder 11 is connected to the case 13 through balls 10 which are located in case and holder grooves.

The holder is established on шлицы a shaft 4, rests against a ring 7 and is fixed on a shaft by a lock ring 12. This ring freely passes In the compressed condition through шлицевое connection of a holder 11 that allows both to connect, and to separate the hinge and a shaft.

The case of the internal hinge 1 differs from the case of the external hinge of 13 that has direct grooves.

GOOD ADVICE Hinges of drives are very durable, their settlement resource is almost equal to a car resource. However in operation them change or repair often enough. Such work is expensive enough and labour-consuming. Seriously to save, regularly check a condition of protective covers of hinges and immediately replace them at the slightest damages. If water or a dust gets to the hinge through the damaged cover, it will fail through some hundreds kilometres of run. The tight hinge wears out extremely slowly.

It be required to you: keys «on 13», «on 17», «on 27», a key for nuts of wheels.

1. Disconnect forward propeller a shaft from a reducer of the forward bridge (Removal and installation карданной transfers »see«).

2. Will hang out the car and remove forward wheels.

3. Disconnect shock-absorbers from the bottom levers of a forward suspension bracket («Replacement of the shock-absorber of a forward suspension bracket» see).

4. Turn on on three nuts of fastening of cases of bearings of the internal hinge of the right and left drives.	5. Turn out a bolt of fastening of the right cover of the bearing of a reducer of the forward bridge to a cross-beam of a forward suspension bracket.

6. Turn away four nuts of fastening скоб suspension brackets of a reducer of the forward bridge.	7. Turn away a nut and remove a bolt of fastening of the left cover of the bearing of a reducer of the forward bridge to a cross-beam of a forward suspension bracket.

8. Raise a reducer of the forward bridge and fix it in this position by any accessible way.	9. Remove a cap of a nave of a forward wheel and turn away a nave nut.
