Why Can't a New Energy Vehicle Shift Gears?

[DeLuna]

The reasons why a new energy vehicle cannot shift gears are as follows: Positioning Ball Head Loses Function: The positioning component of the gear lever's positioning ball head loses function, allowing the gear lever to rotate freely around its own axis, making it impossible to accurately control the gear position. This may be due to the wear of the spherical working surface at the lower end of the gear lever, preventing it from controlling the shift fork or the shift head's groove, making both gear engagement and disengagement impossible. For the former, the fault can be eliminated through repair; for the latter, the gear lever must be replaced. Clutch Cannot Disengage: The clutch cannot fully disengage, while the transmission's shifting mechanism operates normally. This fault can be resolved by adjusting the clutch or replacing certain clutch components to ensure the clutch has appropriate free play and disengagement clearance. Shift Fork Loosens: The shift fork is loose, severely bent, deformed, or worn. In this case, the gear lever's movement reaches the position, but the shift fork's movement does not, causing severe impact and inability to engage the gear. This situation requires opening the transmission cover for inspection and repair, and replacing the shift fork if necessary.
