Working Principle
Function of gear transmission
1.Variable speed: By meshing 2 gears of different sizes, the speed of the gears can be changed. For example, the gearbox gear can reduce or increase the speed from the engine to meet the needs of the car;
2.Torque change: The meshing of 2 gears of different sizes changes the transmitted torque while changing the speed of the gears. For example, the car gearbox, the main reducer in the drive axle, can change the torque of the car;
3.Change direction: the power action direction of some vehicle engines is perpendicular to the driving direction of the vehicle. The transmission direction of power must be changed to drive the vehicle. This device is usually the main reducer and differential of the car.
Gear transmission has the advantages of high transmission efficiency, compact structure, reliable gear transmission, long service life and stable transmission ratio. Its transmission efficiency can reach 99%. Among the commonly used mechanical transmissions, gear transmission has high efficiency; its disadvantage is that compared with belt transmission and chain transmission, the manufacturing and installation accuracy of gears are high, and the price is more expensive. It is not suitable for transmission with too large distance between shafts.

Spur gear and helical gear
Spur gears enter and exit meshing along the whole tooth width at the same time. Its transmission efficiency is very high. Its disadvantages are poor stability, impact and noise.
The tooth meshing process of helical gear is longer than that of spur gear, and the number of teeth participating in meshing is also more than that of spur gear. Therefore, the helical gear transmission is stable, the bearing capacity is strong, and the noise and impact are small. The main disadvantage of helical gear is that the axial component force will be generated when the helical gear surface is subjected to the normal force, and the thrust bearing needs to be installed, which complicates the structure.
Lubrication of gear transmission
There is relative sliding and friction between gear transmission tooth surfaces, which will cause tooth surface wear, increase transmission power consumption and reduce transmission efficiency. Therefore, lubricant must be used to reduce wear and accelerate heat dissipation. This lubricant is gear oil. Different kinds of gears on the car are lubricated with different gear oils, which must not be added wrong. For example, automatic transmission oil and CVT transmission oil cannot be mixed.

How does a differential gear distribute power between the wheels?
A differential gear is responsible for distributing power between the wheels of a vehicle, allowing them to rotate at different speeds while maintaining torque transfer. Here’s a detailed explanation of how a differential gear accomplishes this:
1. Power Input:
The differential gear receives power from the transmission or driveshaft connected to the engine. This power is transmitted to the differential assembly, which is typically located in the axle housing.
2. Ring and Pinion Gears:
Within the differential assembly, the power from the driveshaft is transferred to the ring and pinion gears. The ring gear is a large gear that surrounds the differential assembly, while the pinion gear is a smaller gear connected to the driveshaft. The interaction between these gears allows the power to be redirected.
3. Side Gears and Spider Gears:
The ring gear is connected to side gears, also known as bevel gears, through a set of small gears called spider gears. The side gears are attached to the axle shafts, which are responsible for transmitting power to the wheels. The spider gears allow the side gears to rotate independently of each other while maintaining torque transfer.
4. Differential Action:
As the vehicle moves, the differential gears enable the wheels to rotate at different speeds during turns. When the vehicle is moving in a straight line, the spider gears rotate smoothly, allowing equal power distribution to both wheels. However, during a turn, the inside wheel travels a shorter distance than the outside wheel, causing them to rotate at different speeds.
5. Speed and Torque Distribution:
The differential gear adjusts the speed and torque distribution between the wheels based on their rotational differences. When the vehicle is turning, the spider gears allow one wheel to rotate faster than the other, ensuring that torque is transferred to the wheel with better traction. This allows the wheels to rotate at different speeds, preventing tire scrubbing and providing smooth cornering.
6. Limited-Slip and Locking Differentials:
In certain differential systems, such as limited-slip differentials or locking differentials, additional mechanisms are incorporated to enhance traction and power distribution. Limited-slip differentials use clutch packs or friction plates to provide a predetermined amount of resistance, allowing some speed differentiation between the wheels while still transferring power. Locking differentials, on the other hand, lock the side gears together, ensuring equal torque distribution to both wheels, regardless of traction conditions.
7. Differential Types:
There are various types of differentials, including open differentials, limited-slip differentials, electronic differentials, torque vectoring differentials, and more. Each type has its own mechanisms and technologies to distribute power between the wheels effectively, depending on the vehicle’s requirements and driving conditions.
In summary, a differential gear distributes power between the wheels by utilizing a system of gears, including ring and pinion gears, side gears, and spider gears. The differential action allows the wheels to rotate at different speeds during turns, ensuring smooth cornering and preventing tire scrubbing. Additional mechanisms, such as limited-slip or locking differentials, can further enhance traction and power distribution in various driving conditions.
What is the process for diagnosing and repairing a differential gear issue?
Diagnosing and repairing a differential gear issue involves several steps to identify the problem accurately and implement the necessary repairs. Here’s a detailed explanation of the process:
- Initial Inspection: The process begins with a visual inspection of the differential gear assembly and surrounding components. This includes checking for any signs of leaks, damage, or abnormal wear. The technician will also listen for unusual noises, such as grinding, whining, or clunking sounds, which can indicate potential issues.
- Fluid Inspection: The next step is to inspect the differential gear oil. The technician will check the fluid level and condition. Contaminated or low fluid levels can contribute to differential problems. If the fluid appears dirty, metallic, or has a burnt smell, it may indicate internal damage or excessive wear.
- Test Drive: A test drive is often conducted to observe the vehicle’s behavior and confirm the presence of any differential gear issues. The technician will pay attention to abnormal noises, vibrations, or handling characteristics that may point to specific problems within the differential assembly.
- Differential Disassembly: If a differential issue is suspected, the technician may need to disassemble the differential assembly for a more detailed inspection. This involves removing the driveshaft, axles, and other components to gain access to the differential gears. The differential housing and gears are carefully inspected for signs of wear, damage, or misalignment.
- Measurement and Evaluation: Precision measurements are taken to assess the condition of the differential gears, bearings, and related components. This may involve using specialized tools to check gear backlash, gear tooth wear, bearing clearances, and other critical parameters. These measurements help determine the extent of the problem and whether components need to be repaired or replaced.
- Component Repair or Replacement: Based on the evaluation, the technician will determine the appropriate repair or replacement actions. Damaged or worn components such as gears, bearings, seals, or shims may need to be replaced. In some cases, the entire differential assembly may need to be replaced if the damage is extensive or the cost of repairs outweighs replacement.
- Reassembly and Adjustment: Once the necessary repairs or replacements have been made, the differential assembly is reassembled with new components. Proper adjustments are made to ensure correct gear meshing, preload, and backlash. The technician will also refill the differential with the recommended fluid and perform any additional adjustments or calibrations as required.
- Final Testing: After reassembly, a final test drive is conducted to verify that the differential gear issue has been successfully resolved. The technician will listen for abnormal noises, monitor handling characteristics, and assess overall performance to ensure proper functionality of the repaired differential.
In summary, diagnosing and repairing a differential gear issue involves an initial inspection, fluid inspection, test drive, differential disassembly, measurement and evaluation, component repair or replacement, reassembly and adjustment, and final testing. This systematic process helps identify the problem, determine the necessary repairs, and restore the differential gear to proper working condition.
Can you explain the concept of torque distribution in a differential gear?
Torque distribution is a fundamental concept in a differential gear that refers to the way rotational force is distributed among the wheels of a vehicle. Here’s a detailed explanation:
In a vehicle equipped with a differential gear, torque is transmitted from the engine to the differential, and then further distributed to the wheels. The differential gear ensures that torque is divided between the wheels, allowing them to receive power and propel the vehicle forward.
1. Power Input:
The torque distribution process begins with the power input from the engine. The engine generates rotational force, or torque, which is transmitted through the drivetrain to the differential gear.
2. Differential Assembly:
Within the differential gear, torque is distributed among several components, including the ring gear, pinion gear, side gears, and spider gears. The specific arrangement may differ depending on the type of differential used.
3. Side Gears and Spider Gears:
The side gears are connected to the axle shafts, which extend to the wheels. The spider gears, also known as planetary gears, are positioned between the side gears. When torque is applied to the differential assembly, it is transferred to the side gears through the spider gears.
4. Equal Torque Distribution:
In a straight-line driving scenario, where both wheels have equal traction and are rotating at the same speed, the spider gears rotate freely on their respective shafts. This allows the side gears to rotate at the same speed as the differential case, resulting in equal torque distribution to both wheels. As a result, both wheels receive an equal share of power from the differential.
5. Unequal Torque Distribution:
During turns or when one wheel encounters different traction conditions, the wheels need to rotate at different speeds. In this situation, the spider gears are forced to rotate along with the side gears due to the difference in rotational speeds between the two wheels.
As the spider gears rotate, they allow the side gears to rotate at different speeds, compensating for the variation in wheel speeds. This results in unequal torque distribution, with the outer wheel (on the outside of the turn) receiving more torque and the inner wheel (on the inside of the turn) receiving less torque. The differential gear enables this torque differentiation, ensuring that the wheels can rotate independently while still receiving power from the differential.
6. Optimizing Traction:
The torque distribution in a differential gear plays a crucial role in optimizing traction. Unequal torque distribution allows the wheel with better traction to receive more power, maximizing the vehicle’s ability to maintain forward motion. This is particularly beneficial in situations where one wheel is on a slippery surface or encounters reduced traction conditions.
7. Differential Types:
It’s important to note that different types of differentials can provide varying torque distribution characteristics. For example, open differentials primarily distribute torque equally, while limited-slip differentials and locking differentials offer varying degrees of torque biasing to improve traction in specific conditions.
In summary, torque distribution in a differential gear refers to the division of rotational force among the wheels of a vehicle. The differential gear enables equal torque distribution during straight-line driving and unequal torque distribution during turns or varied traction conditions. By optimizing torque distribution, the differential gear ensures efficient power delivery, traction optimization, and overall performance of the vehicle.
