What Causes Gear Disengagement in Manual Transmissions?
1 Answers
Reasons for gear disengagement in manual transmissions: 1. Wear or detachment of the curved working surface at the lower end of the gear lever, excessive wear of the gear lever ball head; 2. Looseness of the gear lever head positioning pin, wear or detachment of the positioning pin, excessive wear of the gear lever ball head; 3. Excessive wear of the lock pin or lock ball in the interlock mechanism of the shift fork shaft, exceeding 0.02mm, resulting in loss of interlock function. A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the drive wheels, enabling the vehicle to achieve varying traction and speed under different conditions such as starting from a standstill, climbing hills, turning corners, and accelerating, while also allowing the engine to operate within a more favorable range. Functions of manual transmissions: 1. Changing the transmission ratio to expand the range of torque and speed variations at the drive wheels, adapting to frequently changing driving conditions; 2. Utilizing the reverse gear to enable the vehicle to move backward while maintaining the engine's rotational direction; 3. Using the neutral gear to interrupt power transmission without shutting off the engine, facilitating engine startup, warm-up, idling, gear shifting, coasting, or temporary stops.
