A drive axle for a light vehicle includes a chain drive and a differential, which comprises a differential cage (2) with a long neck (6, 7) at both sides, balance pinion gears (13) and two axle pinion gears (16), with the axle pinion gears (16) being journaled radially and axially in the differentia

A drive axle for a light vehicle includes a chain drive and a differential, which comprises a differential cage (2) with a long neck (6, 7) at both sides, balance pinion gears (13) and two axle pinion gears (16), with the axle pinion gears (16) being journaled radially and axially in the differential cage (2). Proximal ends of axle shafts (21, 22) are plugged in the axle pinion gears (16) and at the distal ends of the necks (6, 7) in radial bearings (19) of the differential cage (2) and are supported further outwardly in a fixed bearing (33, 34) connected to the vehicle. The axle pinion gears (16) have conical parts (17) at their rear side remote from the balance pinion gears (13) and can cooperate with a conical inner wall of the differential cage (2).

What is claimed is: 1. A drive axle for a light vehicle comprising: a chain drive; and a differential, wherein: the differential includes a differential cage with balance pinion gears and axle pinion gears at a side of a pair of necks, the axle pinion gears being radially journaled in the differential cage or the necks and being axially supported in the differential cage; and proximal ends of axial shafts are plugged rotationally fixedly and displaceably in the axle pinion gears, the axial shafts being supported in a radial bearing at a distal end of the necks of the differential cage and even further outwardly from the distal end of the necks in a fixed bearing connected to the vehicle, wherein a respective brake disk is seated on the axial shafts between the radial bearings and the axial bearings; and wherein a washer disk is provided between the distal end of the necks and the brake disks. 2. The drive axle in accordance with claim 1, wherein the axle pinion gears have conical parts at their rear side remote from the balance pinion gears that cooperate with a conical inner wall of the differential cage. 3. The drive axle in accordance with claim 1, wherein inner walls of the differential cage form a bearing surface for an axial bearing of the axle pinion gears. 4. The drive axle in accordance with claim 1, wherein a chain sprocket is fixedly seated on one of the necks of the differential cage. 5. The drive axle in accordance with claim 1, wherein a clutch sleeve displaceable on the necks is arranged between the chain sprocket and one of the brake disks for a selective rotationally fixed connection of the chain sprocket and the brake disk. 6. The drive axle in accordance with claim 5, wherein the chain sprocket and the brake disks have bores which are distributed regularly over their periphery and into which axially parallel pins in the coupling sleeve fit which are distributed regularly over its periphery. 7. A drive axle for a light vehicle, comprising: a differential including a differential cage having a neck that houses balance pinion gears meshed with axle pinion gears; a pair of shafts including a first end and a second end supported in said differential cage, a chain sprocket rotationally fixedly seated on the neck; a brake disk seated on at least one of the shafts; and a selector sleeve displaceable on the neck disposed between the chain sprocket and the brake disk to operate the differential in a locked mode, wherein the axle pinion gears are rotationally fixedly and displaceably coupled to the shafts at the first end of the shafts, and the neck supports the second end of the shafts. 8. The drive axle of claim 7, wherein the axle pinion gears are journaled radially and axially in the differential cage. 9. The drive axle of claim 7, wherein the axle pinion gears include a conical surface that cooperates with a corresponding conical inner wall of the differential cage. 10. The drive axle of claim 9, wherein the conical surface and conical inner wall simultaneously acts as a radial bearing. 11. The drive axle of claim 7, wherein the selector sleeve is operable to selectively fix the brake disk for rotation with the chain sprocket to restrict relative rotation between one of the shafts and the differential cage. 12. The drive axle of claim 7, wherein the chain sprocket and the brake disk each have bores arranged over a periphery thereof, the bores receiving axially parallel pins distributed on the selector sleeve. 13. A drive axle for a light vehicle, comprising: a chain drive; a differential having a cage containing balance pinion gears and axle pinion gears; and axle shafts having proximal ends fixed for rotation with the axle pinion gears, each axle shaft being supported for rotation by an axle bearing, wherein the cage is solely supported for rotation by the axle shafts and includes oppositely extending necks, each neck being supported for rotation by one of the axle shafts and having a distal end proximate one of the axle bearings; the drive axle further including brake disks fixed for rotation with the axle shafts, each brake disk being positioned between a distal end of one of the necks and the corresponding proximate axle bearing; wherein the brake disks restrict axial movement of the cage. 14. The drive axle of claim 13 further including a washer disk provided between the distal end of the necks and the brake disks. 15. The drive axle of claim 13 wherein a chain sprocket is fixedly seated on one of the necks of the differential cage between the proximal and distal ends of the neck.
