Fill in the gaps in the text using the words and word combinations from the text “Rear Axle Gears”

1. From the (1)________________ the movement is transmitted to the (2)____________by the propeller shaft. At the back end of this shaft is a (3)__________________.

2. The (4) ___________________ has two halves. A strong gear (bevel wheel) is fixed to each half.

3. A strong box covers the (5)______________________. This box turns when the axles turn.

4. To one side of this box is fixed a large gear (the crown wheel). When it turns, it turns the box and the axles.

5. The (6) __________________ meshes with the (7) _________________. 6. When the (8) _____________________ turns, it turns the crown wheel and the box and the axles.

7. Round the inside of the box are fixed (9) _________________ small gears (differential pinions). Each pinion can turn freely. These pinions mesh with the (10) __________________ on the axles. The (11) ___________ do not turn when the (12) ______________ is going straight. They make the bevel wheels and the axle turn at the same speed.

8. The outside wheel has farther to go when the car is turning. So it must move (13) _________________ than the inside (14) _________________. So the differential pinions turn when the car is turning. Now (15) ______________________ can travel faster than the inside wheel.
