Motor vehicle e.g. private car, gear box, has double lip sealing device provided between primary shaft and partition to ensure sealing in two directions between lubrication oil of pinions and clutch oil

摘要

#CMT# #/CMT# The gear box has parallel shafts comprising a multidisk clutch (7) and pinions (4) lubricated by an oil, and a clutch compartment (12). A mechanical compartment (11) contains the pinions and is separated from the clutch compartment by a partition (14). The clutch drives a primary shaft (1) traversing the partition. A double lip sealing device (25) is provided between the primary shaft and the partition to ensure a sealing in two directions between the lubrication oil of the pinions and the clutch oil. #CMT#USE : #/CMT# Used for a motor vehicle (claimed) e.g. private car and luxury vehicle, that is utilized on road and city traffic. #CMT#ADVANTAGE : #/CMT# The design of the gearbox increases the transmission torque, and prevents mixing of the clutch oil with the lubrication oil of the pinions by the sealing device, so that the oils can be treated, and transmits high torque without necessitating an oil filter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a gearbox. 1 : Primary shaft 2 : Secondary shaft 3 : Synchronizers 4 : Pinions 7 : Multidisk clutch 11 : Mechanical compartment 12 : Clutch compartment 14 : Partition 25 : Double lip sealing device.
