The invention discloses an electric vehicle transmission structure capable of performing stepless speed change, and belongs to the technical field of transmission devices. The electric vehicle transmission structure capable of performing stepless speed change comprises a motor which is powered by a vehicle-mounted power supply, wherein a first-stage clutch is further arranged on an output shaft ofthe motor; the first-stage clutch is connected to a front belt pulley through a transmission assembly; the front belt pulley is connected to a rear belt pulley through a transmission belt; the frontbelt pulley and the rear belt pulley are both of a pulley structure; and automatic clutches capable of controlling the position gap of a belt on a pulley are arranged on the front belt pulley and therear belt pulley respectively; and the rear belt pulley is used for driving rear wheels of an electric vehicle to rotate; The electric vehicle transmission structure effectively solves problems that acurrent conventional electric vehicle is not obvious in gear shifting and speed changing, serious in energy consumption, prone to generating insufficient power and difficult to adapt to various traffic environments.

    本发明公开了一种能够进行无级变速的电动车传动结构,属于传动装置技术领域;它包括通过车载电源进行供电的电机;在电机的输出轴上还安装有一级离合器;一级离合器通过传动组件与前皮带轮相连接;前皮带轮通过传动皮带与后皮带轮相连;前皮带轮和后皮带轮均为普利盘皮带轮结构,且在前皮带轮和后皮带轮上分别安装有能够控制普利盘上皮带位置间隙大小的自动离合器;后皮带轮带动电动车的后轮转动;本发明有效解决了当前的常规电动车上换挡变速不明显,耗能严重,容易产生动力不足,难以适应各种交通环境的问题。
