Abstract
A mounting for a vehicular traction member, such as an endless track, comprises a trunnion carried by means of two axially separated journal bearings on a hollow hub projecting from a vehicle frame, the hub being an extension of a transmission housing accommodating a planetary-gear train driven by a power shaft. An ancillary shaft coaxial with the power shaft, floatingly disposed within the hub, meshes at opposite ends with internal gear teeth of the trunnion and of a planet carrier forming part of the planetary-gear train, that planet carrier also driving a gear pump for the circulation of oil from a pump within the transmission housing across a space between the two journal bearings in which the oil is cooled through the trunnion wall.
