What does Toyota's 10-speed CVT transmission mean?
1 Answers
Toyota's 10-speed CVT transmission is essentially a combination of what is referred to as an ECVT transmission and a 4AT transmission, forming ten gear ratios. The ECVT is quite similar to an AT transmission; rather than being just a transmission, it is more accurately described as a highly complex drivetrain system, typically used in Toyota's hybrid models. Below is an introduction to transmissions: Introduction: A transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine and can fix or change the gear ratio between the output and input shafts. Functions: Transmissions can be categorized into stepped, continuously variable, and integrated types, with capabilities such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Principle: Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations; whereas automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations.
