OEM Transmission Straight Teethed Bevel Helical Differential Gear with Keyway
Gear transmission relies on the thrust between gear teeth to transmit motion and power, also known as meshing transmission. With this gradual meshing, helical gears operate much more smoothly and quietly than spur gears. Therefore, almost all automobile transmissions use helical gears.Since the teeth on the helical gear present a certain angle, the gears will be under a certain amount of stress when they mesh. Equipment using helical gears is equipped with bearings to withstand this pressure.

Can differential gears be used in electric and hybrid vehicles?
Yes, differential gears can be used in both electric and hybrid vehicles. While electric and hybrid vehicles have different powertrain configurations compared to traditional internal combustion engine vehicles, they still require differential gears to distribute power between the wheels and accommodate speed differences. Here’s a detailed explanation:
1. Electric Vehicles (EVs):
In electric vehicles, the power is provided by one or more electric motors. These motors generate torque directly, eliminating the need for a traditional transmission system with a driveshaft. However, EVs still require differential gears to distribute power between the wheels.
2. Single-Speed Transmissions:
Many electric vehicles use single-speed transmissions, also known as direct-drive systems, which do not require multiple gears for speed variation. In these cases, the differential gear is integrated into the electric motor assembly, allowing it to distribute torque between the wheels.
3. Speed and Torque Distribution:
The differential gear in electric vehicles functions similarly to those in conventional vehicles. It accommodates speed differences between the wheels during turns and adjusts torque distribution to ensure optimal traction and control. This helps prevent wheel slip and allows for smooth cornering.
4. Hybrid Vehicles:
Hybrid vehicles combine an internal combustion engine with one or more electric motors. The powertrain configuration varies depending on the type of hybrid system, such as series hybrids, parallel hybrids, or plug-in hybrids. Despite the presence of an internal combustion engine, differential gears are still utilized in hybrid vehicles.
5. Transmissions in Hybrid Vehicles:
Hybrid vehicles often incorporate transmissions to optimize power delivery and efficiency. These transmissions may include differential gears or specific components that perform similar functions to distribute power between the wheels.
6. Regenerative Braking:
Both electric and hybrid vehicles commonly use regenerative braking systems to capture and store energy during deceleration. Differential gears play a role in transmitting torque from the wheels to the electric motor during regenerative braking, allowing the motor to act as a generator and recharge the batteries.
7. Differential Types:
Electric and hybrid vehicles can utilize various differential types, including open differentials, limited-slip differentials, or electronically controlled differentials. The choice of differential depends on factors such as vehicle performance, traction requirements, and driving conditions.
8. Advancements and Innovations:
With the evolving technology in electric and hybrid vehicles, there are also advancements and innovations in differential systems. Manufacturers are exploring new designs, such as integrated motor and differential units, to optimize power distribution and efficiency in these vehicles.
In summary, differential gears are indeed used in electric and hybrid vehicles to distribute power between the wheels, accommodate speed differences, and ensure optimal traction and control. The specific configuration and integration of differential gears may vary depending on the vehicle’s powertrain design and transmission system.
Can differential gears be used in heavy-duty trucks and commercial vehicles?
Yes, differential gears can be used in heavy-duty trucks and commercial vehicles. In fact, they are an essential component of the drivetrain in most vehicles, including those designed for heavy-duty applications. Here’s a detailed explanation:
Differential gears are crucial for effective power distribution and maneuverability, especially in vehicles with multiple axles or large payloads. Here are some reasons why differential gears are used in heavy-duty trucks and commercial vehicles:
- Torque Distribution: Differential gears enable the proper distribution of torque to the wheels. In heavy-duty trucks and commercial vehicles, which often carry heavy loads, torque needs to be transmitted efficiently to ensure adequate traction and pulling power. The differential gears allow the wheels on the same axle to rotate at different speeds, accommodating varying traction conditions and load distribution.
- Maneuverability: Heavy-duty trucks and commercial vehicles often need to navigate tight turns and maneuver in confined spaces. The differential gears assist in smooth cornering by allowing the outer wheel to rotate faster than the inner wheel during turns. This differential action helps minimize tire scrubbing and reduces stress on the tires, enhancing maneuverability and reducing wear.
- Traction Control: Differential gears play a critical role in maintaining traction on different road surfaces. In heavy-duty trucks and commercial vehicles that encounter varied terrain, such as off-road conditions or slippery surfaces, the differential gears allow power to be sent to the wheels with the most traction. This helps maximize traction and minimize wheel spin, improving vehicle stability and control.
- Load Sharing: Differential gears facilitate load sharing among multiple axles in heavy-duty trucks and commercial vehicles. Vehicles with multiple axles distribute the load across all axles, reducing stress on individual components and improving overall performance and durability. Differential gears ensure that power is appropriately distributed among the axles, optimizing load sharing and preventing excessive strain on specific wheels or axles.
- Off-Road Capability: Heavy-duty trucks and commercial vehicles often need to operate in challenging off-road conditions. Differential gears, particularly those with advanced features like limited-slip differentials or locking differentials, enhance off-road capability by improving traction and preventing wheel slippage. These differential systems provide additional power to the wheels with traction, enabling the vehicle to navigate through rough terrain more effectively.
- Efficiency and Durability: Differential gears in heavy-duty trucks and commercial vehicles are designed to handle high torque loads and endure demanding operating conditions. They are built with robust materials and precision engineering to ensure durability and long service life. Proper maintenance, including regular inspections and fluid changes, helps maintain the efficiency and performance of the differential gears, contributing to the overall reliability of the vehicle.
In summary, differential gears are indispensable in heavy-duty trucks and commercial vehicles. They enable torque distribution, enhance maneuverability, improve traction control, facilitate load sharing, enhance off-road capability, and contribute to overall efficiency and durability. These gears play a crucial role in ensuring the optimal performance and functionality of heavy-duty and commercial vehicles across various applications and operating conditions.
What is a differential gear and how does it work?
A differential gear is a component found in vehicles that allows the wheels to rotate at different speeds while receiving power from the engine. Here’s a detailed explanation:
A differential is commonly used in cars, trucks, and other vehicles with driven wheels. Its primary function is to distribute torque (rotational force) from the engine to the wheels while compensating for differences in wheel speeds, especially during turns or when driving on uneven surfaces.
A typical differential gear consists of several key components:
- Differential Case: It is the outer housing that encloses the differential assembly.
- Ring Gear: The ring-shaped gear located on the inside of the differential case.
- Pinion Gear: The small gear connected to the driveshaft, which meshes with the ring gear.
- Side Gears: Two gears connected to the axle shafts, which mesh with the pinion gear.
- Spider Gears (Planetary Gears): These gears are positioned between the side gears and allow the wheels to rotate at different speeds.
Function and Operation:
When power is transmitted from the engine to the differential, the pinion gear receives the rotational force from the driveshaft and meshes with the ring gear. As the pinion gear rotates, it rotates the ring gear and, in turn, the differential case.
During straight-line driving, when 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, transmitting equal torque to both wheels.
However, when the vehicle turns or one wheel encounters a different traction condition (such as being on a slippery surface), 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 enables the wheels to rotate independently while still receiving power from the differential. The differential allows the outer wheel (on the outside of the turn) to rotate at a higher speed while the inner wheel (on the inside of the turn) rotates at a slower speed.
The differential gear system ensures smooth power delivery to the wheels, improves vehicle stability during turns, and reduces tire wear and stress on the drivetrain components.
It’s important to note that there are different types of differentials, such as open differentials, limited-slip differentials, and locking differentials. Each type has its own characteristics and is suited for different driving conditions and vehicle types.
In summary, a differential gear is a crucial component in vehicles that allows the wheels to rotate at different speeds while distributing power from the engine. By utilizing a combination of gears, it enables smooth and efficient power transmission to the wheels, particularly during turns or when encountering varying traction conditions.
