    • The present invention relates to a powered axle gear (I) for a motor vehicle. The object is to achieve an axle gear which can cope with large driving torques and at the same time be accommodated in an axle beam between the vehicle's tractive wheels. The axle gear comprises a gear housing (10) which accommodates a pinion (40) and a crownwheel (50) for transmission of rotary motion to the vehicle's powered axles (Y1, Y2). To this end, there are two bearings (62, 64), one on each side of the crownwheel (50) and the pinion's centreline (X), with a differential situated between said bearings (62, 64). The bearing (64) situated beyond both the crownwheel (50) and the pinion's centreline (X) has running round it an undivided bearing seat (30) provided with a portion running in the circumferential direction which protrudes over the pinion (40) towards the latter's centreline (X) in a configuration which at least partly overlaps the pinion (40). The invention relates also to a motor vehicle.
    • 本发明涉及一种用于机动车辆的动力轴齿轮(I)。 目的是实现能够应对大的驱动扭矩的轴齿轮,并且同时容纳在车辆牵引轮之间的轴梁中。 轴齿轮包括齿轮壳体(10),该齿轮壳体容纳用于向车辆动力轴(Y1,Y2)传递旋转运动的小齿轮(40)和冠轮(50)。 为此,存在两个轴承(62,64),一个在冠轮(50)和小齿轮的中心线(X)的每一侧上,差速器位于所述轴承(62,64)之间。 位于冠状轮(50)和小齿轮的中心线(X)之外的轴承(64)在其周围延伸有未分开的轴承座(30),该轴承座设有沿圆周方向延伸的部分,该部分在小齿轮(40)上朝向 后者的中心线(X)在至少部分地与小齿轮(40)重叠的构造中。 本发明还涉及一种机动车辆。
