The invention discloses a gear clutch device for an axle driven by a permanent magnet motor of a railway vehicle, which belongs to the field of rail transit equipment and comprises a three-phase permanent magnet motor, a gear box, the axle, a clutch and a thrust component. The gearbox includes a gear input shaft, an input gear, and an output gear. The axle penetrates through the output gear and then is rotationally connected with the output gear. The driving part of the clutch is fixedly connected with the output gear, and the freedom degree of sliding in the axle direction only exists between the driven part of the clutch and the axle. The thrust assembly is arranged on the periphery of the axle and used for controlling separation and reunion of the driving part and the driven part. According to the scheme, the clutch is arranged between the output gear of the gearbox and the axle, so that a clutch structure with a compact space is formed. And when the three-phase permanent magnet motor is in a fault state, the clutch is separated from a linkage state, so that damage to wheels and steel rails is avoided.

    本发明公开了一种轨道车辆永磁电机驱动的车轴用齿轮离合装置,属于轨道交通设备领域,包括三相永磁电机、齿轮箱、车轴、离合器以及止推组件。齿轮箱包括齿轮输入轴、输入齿轮以及输出齿轮。车轴贯穿输出齿轮后与输出齿轮转动连接。离合器的主动部与输出齿轮固定连接,离合器的从动部与车轴之间仅存在沿车轴方向滑动的自由度。止推组件设置于车轴的周围用于控制主动部与从动部的离合。本方案是在齿轮箱的输出齿轮与车轴之间设置离合器,形成了空间紧凑的离合器结构。在三相永磁电机处于故障状态时,使离合器脱离联动状态,避免了车轮和钢轨的损坏。
