The invention discloses a torsional gear shifting device and an electric automobile, the torsional gear shifting device comprises an input shaft and an output shaft, the output shaft is rotatably provided with a first output gear and a second output gear, a power transmission mechanism is arranged between the first output gear and the input shaft, and a magnetic induction transmission mechanism is arranged between the second output gear and the input shaft; the first output gear and the second output gear are provided with a first rotating speed detection element and a second rotating speed detection element respectively, and a synchronizing device is arranged on the output shaft. In the gear shifting process, due to the fact that the magnetic induction transmission mechanism is in the semi-clutch state when transmitting power, the smoothness of gear shifting can be effectively improved, gear shifting with torsion is carried out, and smooth switching between a high gear and a low gear is achieved. Non-contact and non-friction magnetic force is adopted for transmitting kinetic energy, gear shifting is carried out through the magnetic force, high-power torque work can be carried out, the structure is simple, work is stable and reliable, high-power torque transmission is suitable, high practicability is achieved, and the high-power torque transmission device is suitable for large-area application and popularization.
本发明公开了一种带扭变档装置及电动汽车,该带扭变档装置包括输入轴和输出轴,输出轴上转动设有第一输出齿轮和第二输出齿轮,第一输出齿轮与输入轴之间设有动力传输机构,第二输出齿轮与输入轴之间设有磁感应传动机构;第一输出齿轮和第二输出齿轮分别配设有第一转速检测元件和第二转速检测元件,输出轴上设有同步装置。在变档过程中,由于磁感应传动机构在传递动力时为半离合状态,其能够有效的提高变档的平顺性,进行带扭变档,实现高低档位的顺利切换。本发明采用了无接触、无摩擦的磁力传递动能,并通过磁力带扭变档,可进行大功率扭矩工作,其结构简单,工作稳定可靠,适合大功率扭矩传递,具有较高的实用性,适合大面积推广应用。
