Abstract
Official abstract text for this publication.
A transmission includes a bar supporting at least one sensor for measuring an operating parameter of the transmission. The sensor bar is provided with an oil channel for transportation of lubrication oil to at least one component of the transmission.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmission comprising a bar supporting at least one sensor for measuring an operating parameter of the transmission, the sensor bar being provided with an oil channel for transportation of lubrication oil to at least one component of the transmission, wherein an outlet of the oil channel is fluidly connected to a space inside of a tubular shaft of the transmission, and said at least one component is arranged on the tubular shaft and fluidly connected to the oil channel via a radially directed through hole of the tubular shaft extending between the component and the space inside of the tubular shaft, and wherein said at least one sensor is a speed and/or position sensor. 2. A transmission according to claim 1 , wherein the oil channel has an inlet arranged in vicinity of a space arranged inside the transmission for containing oil. 3. A transmission according to claim 2 , wherein a gear wheel of the transmission is arranged for rotating in the oil of the space arranged inside the transmission for containing oil and drawing oil to the inlet of the oil channel. 4. A transmission according to claim 3 , wherein said gear wheel is a final drive gear of a differential of the transmission. 5. A transmission according to claim 1 , wherein the sensor bar is arranged to extend in an axial direction across the transmission enabling transportation of oil in the oil channel from a first side of the transmission to said at least one component at a second side of the transmission. 6. A transmission according to claim 1 , wherein the sensor bar has an inclined open chute forming the oil channel for transportation of oil by gravity. 7. A transmission according to claim 1 , wherein said at least one component is a part of a synchronizer device. 8. A transmission according to claim 1 , wherein said at least one component is a bearing. 9. A transmission according to claim 1 , wherein said at least one sensor is arranged for measuring the speed of a shaft or a gear wheel of the transmission. 10. A transmission according to claim 1 , wherein said at least one sensor is arranged for measuring the position of a gear shifting fork or a sleeve of the transmission.
