    • A device for detecting undesirable vibrations in a vehicle drive line utilizes a sensor that communicates with a controller to indicate undesirable vibrations in a drive line component. In one example, a temperature sensor is placed in a central portion of a universal joint. The temperature sensor preferably is supported within a single housing along with a transmitter that is responsive to the temperature sensor to transmit a signal to a remotely located receiver without using a hardwire connection between the transmitter and receiver. Packaging the temperature sensor, transmitter and a power source within a single housing provides the ability to seal off or close a series of lubrication channels that extend through the universal joint. In another example, a contact-based sensor provides a signal whenever a vibration of a drive line component occurs. The contact-based sensor signal preferably is processed to monitor the number of vibrations over time and a vehicle operator is provided with an indication of the level of vibrations as desired.
    • 用于检测车辆驱动线路中不期望的振动的装置利用与控制器通信的传感器,以指示驱动线路部件中的不期望的振动。 在一个示例中,将温度传感器放置在万向节的中心部分中。 温度传感器优选地被支撑在单个壳体内以及响应于温度传感器的发射器,以将信号发射到位于远程的接收器,而不使用发射器和接收器之间的硬线连接。 在单个外壳内包装温度传感器,变送器和电源可提供密封或封闭一系列通过万向接头延伸的润滑通道的能力。 在另一示例中,每当发生驱动线组件的振动时,基于接触的传感器提供信号。 基于接触的传感器信号优选地被处理以监视随时间的振动次数,并且根据需要向车辆操作者提供振动水平的指示。
