Does the Outlander CVT transmission use a steel belt or chain system?
2 Answers
The Outlander CVT uses a chain system. The CVT transmission, also known as a continuously variable transmission, differs most significantly from other transmissions in that it provides a continuous range of gear ratios, offering better driving stability, smoother operation, and improved fuel economy for motor vehicles. Advantages of CVT transmissions: Since there are no transmission gears like those in conventional automatic transmissions, nor the shifting process of an automatic transmission, the resulting gear-shift jerkiness is eliminated. Therefore, the power output of a CVT transmission is linear, delivering an exceptionally smooth driving experience in practice. Theoretically, a CVT's transmission system can have an unlimited number of gear ratios, allowing for more flexible gear settings. This makes it easier to achieve the balance between gear ratio, speed ratio, performance, fuel consumption, and exhaust emissions in traditional transmission systems. The mechanical efficiency and fuel economy of CVT transmissions are significantly better than those of conventional automatic transmissions, second only to manual transmissions, offering much better fuel efficiency. Disadvantages of CVT transmissions: Compared to traditional automatic transmissions, CVTs are slightly more expensive. Additionally, if operated improperly, they have a higher probability of encountering issues.
As an engineer with extensive research experience in transmission technology, let me discuss the design of the Outlander's CVT transmission. It primarily employs a steel belt drive system, specifically supplied by Jatco, with models such as JF011E or similar series. The steel belt consists of multiple high-tensile steel segments, transmitting power through pressure plates and pulley systems, offering advantages like high transmission efficiency, smooth acceleration, and particularly lower fuel consumption in urban driving conditions. Compared to chain-type CVTs, the steel belt is lighter and requires less maintenance, but it's crucial to regularly replace the CVT fluid to prevent belt wear or slippage. The Outlander has consistently adopted the steel belt solution since its early versions, aligning with its family-oriented positioning that emphasizes comfort and economy over extreme performance. If interested, I recommend consulting the manual or visiting a dealership for a test drive to experience the silky-smooth sensation provided by the steel belt, which also enhances overall vehicle durability and noise reduction.
