一种法兰盘、主动齿轮组件及车辆
摘要：
本发明提供一种法兰盘、主动齿轮组件及车辆，该法兰盘包括法兰盘面和轴颈部，所述轴颈部设置有沿所述轴颈部的径向贯通的通孔和与花键轴上的外花键相配合的内花键，所述通孔内穿装用于与所述花键轴上的外花键抵接的紧固件。通过在法兰盘的轴颈部上设置通孔，从而可以通过紧固件将法兰盘固定在花键轴上，相比于现有技术中采用冲凹的方式对主动齿轮法兰盘进行锁止，可以提高法兰盘锁止的稳定性和可靠性。
摘要（英）：

The invention provides a flange plate, a driving gear assembly and a vehicle. The flange plate comprises a flange plate face and a shaft neck part. The shaft neck part is provided with a through holewhich is in penetration in the radial direction of the shaft neck part, and an inner spline matched with an outer spline on a spline shaft. A fastener used for abutting against the outer spline on thespline shaft penetrates the through hole. The through hole is formed in the shaft neck part of the flange plate, and then the flange plate can be fixed to the spline shaft through the fastener. Compared with the prior art that a concave punching manner is adopted for locking a driving gear flange plate, the flange plate locking stability and reliability can be improved.
