Monitoring the bearing temperature in final drives
In diesel-powered vehicles, the wheelset transmission transfers the drive force coming in from the main transmission to the drive axle, and in electrically-powered vehicles, they transfer the drive force coming from the driving motor to the drive axle. The enormous loads on the bearing and the gear tooth flanks generate heat and are made manageable by lubricating with oil. For safety reasons, temperature monitoring is essential to ensure reliable transmission operation. The bearing temperature is measured by a temperature probe that has been specifically developed and certified for this demanding measurement task.
