Automotive gear slippage primarily occurs due to wear, looseness, damage of transmission components, or improper adjustment of mating clearances. Below are potential causes of gear slippage: 1. Worn, loose, fractured, or missing shift lever locating pins, causing loss of control and random swinging. 2. Corrosion failure of the gearshift fork shaft interlock mechanism; excessive wear and looseness of the shift lever ball head. 3. Conical wear of gears, gear rings, or gear sleeves along the tooth length direction, leading to disengagement under axial forces generated during operation. 4. Excessive corrosion of shift fork shaft grooves, locking pins, etc.; bent or deformed shift forks, or excessive wear between working surfaces and gear ring grooves. 5. Loosening of the rear fixing nut on the secondary shaft, causing axial movement. 6. Loose or disassembled synchronizer locking pins, resulting in cone surface failure.

What Causes Manual Transmission Cars to Shudder When Starting?

The reasons for manual transmission cars shuddering when starting are: 1. Releasing the clutch too quickly; 2. Insufficient engine power; 3. Worn or slipping clutch pressure plate and disc; 4. Dirty throttle body or excessive carbon buildup on fuel injectors; 5. Aging engine mounts. The hazards of manual transmission cars shuddering when starting include: 1. Aggravating engine carbon buildup; 2. Damaging the car's spark plugs; 3. Accelerating the aging process of engine components. A manual transmission, also known as a manual gearbox, requires the driver to manually shift gears by moving the gear lever to change the gear engagement inside the transmission, thereby altering the gear ratio to achieve speed changes. The working principle of a manual transmission involves using the shift fork to change the gear ratio or tooth ratio of the engaged gears, thereby modifying the driving torque to suit different operating conditions.

What are the phenomena of brake deviation?

Brake deviation phenomena include: 1. The car deviates irregularly to the left or right during driving, or shows regular directional deviation; 2. Rear axle sideslip or front wheels losing steering ability, causing the car to lose control and deviate from the original driving direction; 3. Body sway during braking; 4. A feeling of the steering wheel being pulled. The causes of brake deviation are: 1. Inconsistent braking force on both sides of the car's wheels, especially the wheels on both sides of the steering axle; 2. Incoordination of the suspension guide rod and steering system linkage during braking; 3. Improper loading on both sides of the vehicle; 4. Inconsistent road adhesion on both sides.
