What Causes the Inability to Shift Gears in New Energy Vehicles?
1 Answers
New energy vehicles may fail to shift gears due to the following reasons: Malfunction of the Positioning Ball Head: The positioning component of the gear lever's ball head loses its function, allowing the gear lever to rotate freely around its own axis and making it impossible to accurately control the gear position. Alternatively, the spherical working surface at the lower end of the gear lever may wear out, preventing the gear lever from controlling the fork or the fork head's groove, making both gear engagement and disengagement unachievable. For the former issue, repairs can resolve the fault; for the latter, the gear lever must be replaced. Clutch Fails to Disengage: The clutch cannot fully disengage, even though the gearbox's shifting mechanism operates normally. This issue can be resolved by adjusting the clutch or replacing certain clutch components to ensure the clutch has appropriate free play and disengagement clearance. Loose or Damaged Fork: The fork may be loose, severely bent, deformed, or worn out. In this case, the gear lever's movement reaches the intended position, but the fork's movement does not, leading to severe impact and the inability to engage the gear. This situation requires opening the gearbox cover for inspection and repair, and replacing the fork if necessary.
