Electric machine torque key wedges

The disclosure provides electric machine torque key wedges. A stator system for an electric vehicle motor may include a stator having a torque key extending axially from a first stator end; a case configured to surround the stator and defining a case opening to receive the torque key, the case defining a keyway between the torque key and the case opening; a torque key mechanism arranged within thekeyway, wherein the torque key mechanism includes a pair of reciprocally aligned wedges defining a channel through at least one of the wedges; and a bolt insertable at the channel and configured to engage the channel to move at least one wedge and create an interference fit of the torque key mechanism within the keyway to attach the stator to the case. 本公开提供了"电机扭矩键楔形件"。一种用于电动车辆马达的定子系统可包括：定子，所述定子具有从第一定子端轴向延伸的扭矩键；壳体，所述壳体被配置为围绕所述定子，并且限定壳体开口以接收所述扭矩键，所述壳体限定所述扭矩键与所述壳体开口之间的键槽；扭矩键机构，所述扭矩键机构布置在所述键槽内，其中所述扭矩键机构包括一对相互对准的楔形件，所述一对相互对准的楔形件限定穿过所述楔形件中的至少一个的通道；和螺栓，所述螺栓可在所述通道处插入并且被配置为接合所述通道，以移动至少一个楔形件并产生所述扭矩键机构在所述键槽内的过盈配合，从而将所述定子附接到所述壳
