The invention relates to a transmission (4) comprising an electric machine (30), a drive shaft (9), a first input shaft (10), a second input shaft (11) and an intermediate shaft (12), provided with a first spur gear stage (20) having a fixed gear (23) arranged on the first input shaft (10) and a movable gear (24) meshing therewith, the movable gear is rotatably mounted on the intermediate shaft (12) and can be fixed to the intermediate shaft (12) by means of a first switching element (S2). Furthermore, a second spur gear stage (19) is provided with a fixed gear (26) arranged on the second input shaft (11) and a movable gear (25) meshing therewith, which is rotatably mounted on the intermediate shaft (12) and can be fixed to the intermediate shaft (12) by means of a second shift element (S4). The movable gear (24) of the first spur gear stage (20) and the movable gear (25) of the second spur gear stage (19) can be connected to each other in a rotationally fixed manner by means of a third shifting element (S3). Furthermore, a planetary gear stage (31) is provided, the second element (35) of which is connected in a rotationally fixed manner to the second input shaft (11) and the third element (36) of which is coupled to the rotor (32) of the electric machine (30), the first element (34) of which can be connected in a rotationally fixed manner to the drive shaft (9) by actuating a fourth shift element (S6). Two of the elements of the planetary gear stage (31) can also be connected to each other in a rotationally fixed manner by means of a fifth shift element (K).
本发明涉及一种变速器(4),其包括电机(30)、驱动轴(9)、第一输入轴(10)、第二输入轴(11)和中间轴(12),设置有具有设置在第一输入轴(10)上的固定齿轮(23)和与之啮合的活动齿轮(24)的第一正齿轮级(20),所述活动齿轮可旋转地支承在中间轴(12)上并且能通过第一切换元件(S2)固定在中间轴(12)上。还设置有具有设置在第二输入轴(11)上的固定齿轮(26)和与之啮合的活动齿轮(25)的第二正齿轮级(19),所述活动齿轮可旋转地支承在中间轴(12)上并且通过第二切换元件(S4)能固定在中间轴(12)上。第一正齿轮级(20)的活动齿轮(24)与第二正齿轮级(19)的活动齿轮(25)能通过第三切换元件(S3)抗扭转地相互连接。另外设有行星齿轮级(31),该行星齿轮级的第二元件(35)抗扭转地与第二输入轴(11)连接并且该行星齿轮级的第三元件(36)与电机(30)的转子(32)耦合,相对地,通过操纵第四切换元件(S6)该行星齿轮级(31)的第一元件(34)能抗扭转地与驱动轴(9)连接。通过第五切换元件(K)该行星齿轮级(31)的所述元件中的两个元件还能抗扭转地相互连接。
