⚠️ 常见故障与维护
- 常见问题：换挡卡顿、档位不清晰、跳档 / 乱档、漏油、换挡沉重
- 故障原因：内部拨叉轴磨损、定位钢球 / 弹簧失效、法兰面密封垫老化、操纵杆防尘套破损
- 维护建议：定期检查防尘套是否破损，避免泥水进入导致卡滞；更换变速箱油时，同步检查操纵机构润滑状态、
- Power Input: The engine flywheel drives the clutch pressure plate to rotate, which in turn spins the ceramic clutch disc via clamping force.
- Power Disconnection: When the clutch pedal is depressed, the release bearing pushes the pressure plate’s diaphragm spring, releasing the clutch disc and cutting power between the engine and transmission.
- Shift Operation: The cab gear lever, connected via rods/cables, actuates the shift mechanism in the transmission top cover, moving the shift fork shafts to complete gear changes.
- Heavy-Load Starting: As the clutch pedal is released, power is re-engaged. The 1st-speed driving gear in the transmission provides a high-torque gear ratio to drive the vehicle during heavy-load starts and hill climbing.
- Power Output: The transmission sends power to the driveshaft and drive axle, which ultimately transfers it to the steer/drive wheels.
