The new 6 speed FF manual transaxle, M6LF1 has been developed by adding one more gear on the output shaft of existing M5HF2.
Following is the main features comparing with M5HF2.
As same as M6GF2 and M5HF2, 3 axis type was applied so that there are two output shafts.
The maximum torque transmitting capacity has been increased by 2 kgf.m
The Input~Diff(215→210) has been reduced by 5mm, this means that the layout and dimension was reduced to get a lower weight (reduced by about 6kgf) and enhanced fuel consumption.
As same as M5HF2, output shaft #1 is for 1st, 2nd, 3rd and 4th gear. Output shaft #2 is for 5th, and reverse gear. 6th gear is attached on the output shaft #2.
Generally, the grinding for the gear is done after heat treatment so that the cost is very high but ensures best durability and minimum noise in the transmission. In case of 1st gear and reverse gear, the time to be meshed in whole driving life is not so long so that the grinding treatment was not applied. The transmission case structure is almost same. It consists of two cases; clutch housing and transmission case as same as M5HF2.
Three kinds of synchronizer mechanism which was known in the modern technology; single, double and triple synchronizer system has been applied as shown in the table.
A module type control and shift lever assembly has been applied as same as one for M5HF2.
