Abstract
A final drive comprising a lubrication system is provided. The final drive comprises a differential housing and a reaction plate, wherein the reaction plate is mounted to the differential plate. The final drive also comprises a shaft and a friction disc. The shaft is rotatably disposed with differential housing, and the friction disc, which has a lubrication hole, is mounted about the shaft. The lubrication system comprises a differential supply passage positioned in the differential housing, and it also comprises a plate passage positioned in the reaction plate. The plate passage is in fluid communication with the differential supply passage, and the plate passage is in intermittent fluid communication with the lubrication hole.
Claims15
A final drive comprising a lubrication system, the final drive further comprising a differential housing, a reaction plate mounted to the differential housing, a shaft rotatably disposed within the differential housing, and a friction disc mounted about the shaft and fixed for rotation therewith, the friction disc comprising a lubrication hole and inner and outer bands of friction lining that are each concentric with the shaft, the lubrication hole being positioned between the inner and outer bands of friction lining, the lubrication system, comprising:
- a differential supply passage positioned in the differential housing;
- and
- a plate passage, wherein the plate passage is positioned in the reaction plate, the plate passage is in fluid communication with the differential supply passage, and the plate passage is in intermittent fluid communication with the lubrication hole.
