Patent ID: 7955209

Claim:
A differential gear for a motor vehicle, comprising: a powered drive cage; a first driven shaft and a second driven shaft connected with the drive cage via a planetary or differential gear; a stationary gear housing; an intermediate gear with a planetary unit is provided with the first driven shaft, the planetary unit comprising: a planetary wheel support; and a planetary wheel pair comprising a first planetary wheel and a second planetary wheel arranged coaxially with respect to each other and are connected with each other so as to be fixed against rotation relative to each other, the first planetary wheel and the second planetary wheel having different effective diameters, wherein the planetary wheel pair is arranged on planetary wheel pair shafts, which are connected with the planetary wheel support; a first sun wheel, which is connected with the drive cage so as to be fixed against rotation relative to the drive cage and is engaged with the first planetary wheel; a second sun wheel, which is connected with the second driven shaft so as to be fixed against rotation relative to the second driven shaft and is arranged coaxially with the first sun wheel; a brake device comprising: a breaking force applicator which causes a breaking action that generates a braking torque that brakes the planetary unit with respect to the stationary gear housing, and wherein the planetary unit comprises active surfaces for introducing the breaking torque into the planetary unit, wherein the active surfaces are provided within a first area defined by a first plane laterally spaced from the planetary wheel pair and within a second area defined by a second plane laterally spaced from the planetary wheel pair, wherein the planetary wheel pair is substantially positioned between the first and second areas and the first and second planes are perpendicularly intersected by an axis of rotation of the planetary wheel pair; a first friction disk at the first area and a second friction disk at the second area, wherein the first friction disk and the second friction disk introduce the braking torque into the planetary unit, wherein the braking force applicator is arranged at only the first area and the second friction disk arranged at the second area is designed as a support disk, which counteracts a braking power and the braking torque at the stationary gear housing.
