A transmission system associated with a vehicle includes a shaft that rotates about an axis of rotation. The shaft is coupled to the gear set. The transmission system includes a target wheel coupled to and rotating with the gear set. The target wheel includes at least one void. The transmission system includes a giant magnetoresistance (GMR) sensor spaced apart from the target wheel by a gap. A giant magnetoresistance (GMR) sensor is configured to observe at least one void of the target wheel to determine a rotational speed of the shaft based on a giant magnetoresistance (GMR) effect. The transmission system also includes a rotating housing located in a gap between the target wheel and a giant magnetoresistance (GMR) sensor.
与交通工具相关联的变速器系统包括围绕旋转轴线旋转的轴。轴联接到齿轮组。变速器系统包括联接到齿轮组并且随齿轮组旋转的靶轮。靶轮包括至少一个空隙。变速器系统包括巨磁阻(GMR)传感器,GMR传感器通过间隙与靶轮间隔开。巨磁阻(GMR)传感器被配置为观察靶轮的至少一个空隙,以基于巨磁阻(GMR)效应确定轴的旋转速度。变速器系统还包括位于靶轮与巨磁阻(GMR)传感器之间的间隙中的旋转壳体。
