Most transaxles primarily use which type of gears?

• A. Straight-cut gears
• B. Spur gears
• C. Helical-cut gears
• D. Crowned gears

Answer: (C)

Most transaxles primarily use helical-cut gears because these gears are designed to provide smoother engagement compared to other types. The angled teeth of helical gears allow for gradual contact between gear pairs, which reduces shock loads and noise during operation. This results in better power transmission and improved overall efficiency, making them the preferred choice in many automotive applications where performance and comfort are key considerations. In addition, helical gears can handle higher load capacities due to the increased surface contact area as the teeth engage, which enhances durability. Their design also contributes to less backlash compared to straight-cut and spur gears, leading to smoother and more responsive operation. These characteristics make helical gears particularly suitable for transaxles, where precision and reliability are essential for optimal vehicle performance.
