STRUCTURE FOR REDUCING SHIFTING EFFORT IN HEAVY-DUTY TRANSMISSION

摘要

A structure for reducing the effort required to shift gears in a heavy-duty transmission. A shifting fork shaft is arranged in the case of a transmission. A linear bearing is arranged between the outer surface of the shift fork shaft and the inner surface of the case, thus transforming the sliding friction of a large area into the rolling friction of each rolling element of the linear bearing. The present structure effectively reduces the effort required to shift gears, improves shift smoothness and overcomes the poor wear-resistance and damage caused by pulling in conventional shift fork structures, while also reducing the likelihood of irreparable damage to the transmission case caused by over-grinding of holes on said case.
