Drive shafts transmit motion from the engine to the gearbox, and from the gearbox to the rear axle. On vehicles with three axles, it is possible to have two drive shafts, one for each pair of wheels. For military vehicles with four guide and driving wheels, there is one drive shaft for each wheel with double joints.
On cars the drive shaft is constituted by a single tubular-section piece with elastic joints at either end for small cars, or universal joints with roller bearings for more powerful cars, three-wheelers and light-duty trucks.
On industrial vehicles, due to the shaking of the axle, drive shafts are equipped with a coupling with a sliding grooved edge in order to accommodate variations in length.
For buses and lorries with long wheelbases, drive shafts are made in two or more segments which are connected by means of a swivelling support attached to a crossbar on the chassis.
In recent years, Italgiunti has succeeded in updating its range of products in stock, above all with the introduction of four-wheel drive vehicles to the marketplace, with the possibility of repairing or supplying a brand new joint which is not identical to but perfectly interchangeable with the old one, produced entirely in Italy for vehicles such as the following:
