The invention relates to a transmission (4) comprising an electric machine (30), a first input shaft (10), a second input shaft (11) and a countershaft (12). A first spur gear stage (20) is provided, which has a fixed gear (23) arranged on the first input shaft (10) and a movable gear (24) meshing therewith, which is rotatably mounted on the countershaft (12) and can be fixed to the countershaft (12) by means of a first shift element (S2), and a second spur gear stage (19) is provided, which is rotatably mounted on the first input shaft (10) and can be fixed to the second input shaft (10) by means of a second shift element (S2). The second spur gear stage has a fixed gear (26) arranged on the second input shaft (11) and a movable gear (25) meshing therewith, which is rotatably mounted on the countershaft (12) and can be fixed to the countershaft (12) by means of a second shift element (S4). Furthermore, 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 stage (31) is provided, the second element (35) of which is non-rotatably connected 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 the planetary stage (31) can be fixed by actuating a fourth switching element (B) and the two elements (34, 35, 36) of the planetary stage (31) can be connected to each other in a rotationally fixed manner by closing a fifth switching element (K).

    本发明涉及一种变速器(4),包括电机(30)、第一输入轴(10)、第二输入轴(11)和副轴(12)。在此设置有第一正齿轮级(20),该第一正齿轮级具有一个设置在第一输入轴(10)上的固定齿轮(23)和一个与之啮合的活动齿轮(24),该活动齿轮可旋转地支承在副轴(12)上并且可通过第一切换元件(S2)固定在副轴(12)上,还设置有第二正齿轮级(19),该第二正齿轮级具有一个设置在第二输入轴(11)上的固定齿轮(26)和一个与之啮合的活动齿轮(25),该活动齿轮可旋转地支承在副轴(12)上并且可通过第二切换元件(S4)固定在副轴(12)上。此外,第一正齿轮级(20)的活动齿轮(24)和第二正齿轮级(19)的活动齿轮(25)可通过第三切换元件(S3)不可相对转动地相互连接。此外,设置有行星级(31),该行星级的第二元件(35)不可相对转动地与第二输入轴(11)连接并且该行星级的第三元件(36)与电机(30)的转子(32)耦联,所述行星级(31)的第一元件(34)可通过操作第四切换元件(B)固定并且所述行星级(31)的两个元件(34、35、36)可通过闭合第五切换元件(K)不可相对转动地相互连接。
