Is Toyota's Transmission CVT or AT?
1 Answers
Toyota vehicles utilize both types of transmissions. The differences between them are as follows: 1. Principle: AT (Automatic Transmission) employs a torque converter, but its automatic torque variation range is limited. Therefore, multiple planetary gear sets are connected in series behind the turbine to enhance efficiency. The hydraulic control system automatically operates the planetary gears in response to engine changes, achieving automatic torque variation. CVT (Continuously Variable Transmission) uses conical pulleys that can tighten or loosen under hydraulic pressure, squeezing the steel belt to adjust the width of the V-shaped groove. When the conical pulleys move inward and tighten, the steel belt is pushed outward from the center; conversely, it moves inward. This changes the diameter of the pulley driven by the steel belt, altering the gear ratio. 2. Usage: AT does not require a clutch for shifting, has fewer gears with significant changes, and ensures smooth engagement, making it easy to operate. This provides convenience for drivers and comfort for passengers. CVT lacks the traditional gear sets of automatic transmissions, eliminating the shift process and associated jerking sensations. As a result, CVT delivers linear power output, offering an exceptionally smooth driving experience.
