Cooling circuit for motor vehicle transmission has fan mounted at end of drive shaft mounted in end of housing via roller bearings

摘要

Cooling circuit has a fan (21) mounted at the end of the drive housing on a shaft (22) mounted in roller bearings (23) in the housing (11). The fan shaft is driven by bevel gears (25,26) from a drive shaft (13) perpendicular to the fan shaft. The fan shaft can be mounted in a separate bush (24) fixed to the front face of the drive housing. The drive shaft from which the fan shaft is driven can be the fast shaft of the drive.
