The two selector drums are assigned to the gears: Selector drum 1/3, 5: Gear 1, 3 and 5 selector drum 2/4, R: gear 2, 4 and reverse gear Through corresponding rotation of the selector drums the sliding blocks running in the grooves are deflected to the left or right. As a result the corresponding shift collars are displaced in turn via the shift forks and thus the gears are shifted. Because when shifting out of a gear and shifting into the next gear different selector drums are used, the gearshift may overlap when it is executed: While the current gear is disengaged, the next gear is moved up to the synchromesh. When the shift collar has separated the previous gear, the new gear is then synchronized and engaged. The overlap reduces the time for the gear change significantly, it is shorter than that of gear change with only one selector drum.

in and evaluated by the electronics within the electronic selector lever module control unit. The signals corresponding to the shift lever positions are passed on via the Controller Area Network (data bus/CAN bus) (CAN) to the automated manual transmission control unit (N15/6). The selector lever module control unit locks or releases the mechanical park lock via a cable. The mechanical park pawl is locked if the selector lever is in "P". BASIC KNOWLEDGE > TRANSMISSION MOTOR SELECTOR DRUM DRIVE COMPONENT DESCRIPTION - GF26.19-P-1005MCC > TRANSMISSION 717.480 /481 /482 /483 in MODELS 451.3 /4 Location The transmission motors are located in the transmission housing. Task Depending on the shift request from the automated manual transmission control unit (N15/6) the transmission motors adjust the selector drums via two-stage spur-gear unit. Actuation is pulse-width modulated by two output stages with four electronic switches each. The transmission motor is braked when the specified position is reached. It can, if necessary, be actuated with opposing voltage, if an overshoot beyond the specified position is to be prevented or reversed. Actuation of the transmission motors is monitored by the incremental sensors, which are located on each motor shaft. These detect the rotation angle and direction of rotation of the respective transmission motor using an integrated system of Hall sensors. Actuation of transmission motors is only required for carrying out shift operations. Upon reaching a specified position a bolt engages in the locking groove of the selector drum. This suffices to retain the selected gear.

TRANSMISSION 717.480 /481 /482 /483 in MODEL 451.3/4 Design Function The shift forks are displaced by the selector drums parallel to the transmission shafts. They in turn slide the shift collars on the input shaft or the main shaft towards the respective idler gears. The actuation of the shift forks is conducted by two independent selector drums, each of which has a groove. The sliding blocks for two shift forks run in each groove: Selector drum 1/3, 5: Sliding block of shift fork for shift collar 1/3 Sliding block of shift fork, shift collar 5 Selector drum 2/4, R: Sliding block of shift fork for shift collar 2/4 Sliding block of shift fork for sliding gear, reverse gear The positions of both sliding blocks in the same groove are offset to each other by 120°. If a sliding block shifts a shift fork out of the center position, the other sliding block is located in the straight area of the groove (in the center position of the associated shaft fork).

Before the shift collar (3) positively connects the sleeve carrier with the corresponding idler gear, the tapered pairs of faces contact the clutch body (1), synchronizer ring (2) and, where applicable, an intermediate ring. The gear on engine side is brought to the RPM of the gear on the output side, only then do the locking splines (4) enable the further travel of the shift collar.

The two selector drums are assigned to the gears: Selector drum 1/3, 5: Gear 1, 3 and 5 selector drum 2/4, R: gear 2, 4 and reverse gear Through corresponding rotation of the selector drums the sliding blocks running in the grooves are deflected to the left or right. As a result the corresponding shift collars are displaced in turn via the shift forks and thus the gears are shifted. Because when shifting out of a gear and shifting into the next gear different selector drums are used, the gearshift may overlap when it is executed: While the current gear is disengaged, the next gear is moved up to the synchromesh. When the shift collar has separated the previous gear, the new gear is then synchronized and engaged. The overlap reduces the time for the gear change significantly, it is shorter than that of gear change with only one selector drum.

Location The rpm sensor is mounted to the transmission housing. Task The rpm sensor determines the rotational speed of the input shaft. The determined speeds of the crankshaft and input shaft are used to monitor the clutch operation. The speeds of the input shaft and the drive wheels are used to determine the actual gear engaged. The diagram illustrates the oscilloscope picture of an rpm sensor.

in and evaluated by the electronics within the electronic selector lever module control unit. The signals corresponding to the shift lever positions are passed on via the Controller Area Network (data bus/CAN bus) (CAN) to the automated manual transmission control unit (N15/6). The selector lever module control unit locks or releases the mechanical park lock via a cable. The mechanical park pawl is locked if the selector lever is in "P". BASIC KNOWLEDGE > TRANSMISSION MOTOR SELECTOR DRUM DRIVE COMPONENT DESCRIPTION - GF26.19-P-1005MCC > TRANSMISSION 717.480 /481 /482 /483 in MODELS 451.3 /4 Location The transmission motors are located in the transmission housing. Task Depending on the shift request from the automated manual transmission control unit (N15/6) the transmission motors adjust the selector drums via two-stage spur-gear unit. Actuation is pulse-width modulated by two output stages with four electronic switches each. The transmission motor is braked when the specified position is reached. It can, if necessary, be actuated with opposing voltage, if an overshoot beyond the specified position is to be prevented or reversed. Actuation of the transmission motors is monitored by the incremental sensors, which are located on each motor shaft. These detect the rotation angle and direction of rotation of the respective transmission motor using an integrated system of Hall sensors. Actuation of transmission motors is only required for carrying out shift operations. Upon reaching a specified position a bolt engages in the locking groove of the selector drum. This suffices to retain the selected gear.

TRANSMISSION 717.480 /481 /482 /483 in MODEL 451.3 /4 Design Function The shift forks are displaced by the selector drums parallel to the transmission shafts. They in turn slide the shift collars on the input shaft or the main shaft towards the respective idler gears. The actuation of the shift forks is conducted by two independent selector drums, each of which has a groove. The sliding blocks for two shift forks run in each groove: Selector drum 1/3, 5: Sliding block of shift fork for shift collar 1/3 Sliding block of shift fork, shift collar 5 Selector drum 2/4, R: Sliding block of shift fork for shift collar 2/4 Sliding block of shift fork for sliding gear, reverse gear The positions of both sliding blocks in the same groove are offset to each other by 120°. If a sliding block shifts a shift fork out of the center position, the other sliding block is located in the straight area of the groove (in the center position of the associated shaft fork).

Before the shift collar (3) positively connects the sleeve carrier with the corresponding idler gear, the tapered pairs of faces contact the clutch body (1), synchronizer ring (2) and, where applicable, an intermediate ring. The gear on engine side is brought to the rpm of the gear on the output side, only then do the locking splines (4) enable the further travel of the shift collar. The shift collar travel from neutral to complete engagement in the relevant idler gear is approx. 7.7 mm.
