The invention relates to a gearwheel arrangement (16) for establishing a gear stage in a transmission (17) in an electric vehicle, comprising a pinion (22) and an output gearwheel (23). The pinion (22) and the output gearwheel (23) are designed as spur gears, which are in engagement with one another in order to bring about a transmission of a drive power of an electric machine (18). A ratio of a gearwheel diameter to a module of the output gearwheel (23) is in the range of 140 to 350, preferably in the range of 205 to 315, and particularly preferable in the range of 205 to 230. The invention further relates to an electric vehicle transmission (17) having such a gearwheel arrangement (16), and to a drive train (15) for an electric vehicle (10) having an electric machine (18), a differential (20), and an electric vehicle transmission (17) such as described.
本发明涉及一种用于在电动车辆传动机构(17)中建立挡位级的齿轮装置(16),该齿轮装置具有小齿轮(22)和从动齿轮(23),其中小齿轮(22)和从动齿轮(23)被设计成彼此啮合的正齿轮,以实现电动机器(18)的驱动动力的传动;并且从动齿轮(23)的齿轮直径与模数的比值在140至350的范围内、优选地在205至315的范围内、并且特别优选地在205至230的范围内。本发明还涉及一种电动车辆传动机构(17),该电动车辆传动机构具有这种齿轮装置(16);以及一种用于电动车辆(10)的动力传动系(15),该动力传动系具有电动机器(18)、差速器(20)以及这种电动车辆传动机构(17)。
