<p>#CMT# #/CMT# The assembly has a load-equalizing main shaft (7) producing individual gears by activating each transmission ratio step. Loose wheels (6) are arranged on the shaft. A fixed wheel (5) is arranged on each of countershafts (3, 4) that are in active engagement with each other. The activation of the step is carried out by actuating a switch element (8). The loose wheels are rotational-fixedly connected with the main shaft by the switch element. An oil pump (13) i.e. internal gear pump, of transmission is axially arranged on the main shaft in a vicinity to a reverse gear producing device (12). #CMT#USE : #/CMT# Assembly for reducing rattle in a transmission of a countershaft design for a motorvehicle i.e. commercial vehicle. #CMT#ADVANTAGE : #/CMT# The oil pump i.e. internal gear pump, of the transmission is axially arranged on the main shaft in the vicinity to the reverse gear producing device, thus reducing rattling noises upto 3 Decibels without additional components, and preventing production of any additional sources of loss in the transmission. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a transmission of a countershaft design. 3, 4 : Countershafts 5 : Fixed wheel 6 : Loose wheels 7 : Load-equalizing main shaft 8 : Switch element 12 : Reverse gear producing device 13 : Oil pump.</p> |
