Patent number: 7195103
Abstract: An oil supplying device (34, 36, 38) for a vehicle transmission (2) having one transmission housing (4, 6) with gears (10, 12, 16, 18, 22) situated upon shafts (8, 14, 20) and having teeth, bearings in which gears (10, 12, 16, 18, 22) and shafts (8, 14, 20) are rotatably mounted and one switch gear (30, 32, 50) suited to connect the gears (10, 12, 16, 18, 22) and shafts (8, 14, 20) for a transmission of torque. The device has an oil collecting duct (34) arranged on movable elements (32, 50) of the switch gear (30, 32, 50) which moves with the elements (32, 50) of the switch gear (30, 32, 50) and which extends substantially through the part in the transmission housing (4, 6) having all the gears (10, 12, 16, 18, 22). The oil collecting duct (34) has at least one opening (36, 38) which during movements of the elements (32, 50) of the switch gear (30, 32, 50) coats areas within the transmission housing (4, 6) on which the bearings and teeth are situated.
