Where is the Roewe CVT transmission produced?
2 Answers
Roewe CVT transmission is independently developed and produced by SAIC. Below is relevant information about CVT transmissions: 1. Concept: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving excellent fuel economy, power performance, and driving smoothness while reducing emissions and costs. 2. Working principle: In a CVT drive system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley actually consists of two conical discs forming a V-shaped structure. The engine shaft connects to the small pulley, which drives the large pulley via the steel belt. The secret lies in the special pulley: the CVT drive pulley has a unique structure, divided into movable left and right halves that can move closer together or farther apart. The conical discs can tighten or expand under hydraulic pressure, squeezing the steel belt to adjust the width of the V-shaped groove. When the conical discs move inward and tighten, the steel belt is pushed outward (centrifugally) under the pressure of the discs; conversely, it moves inward. This changes the diameter of the disc driven by the steel belt, thereby altering the gear ratio.
I have studied cars for many years. The CVT transmissions used by Roewe primarily incorporate core technologies provided by Japan's Aisin Seiki, which are then assembled and produced in SAIC Motor's factories in China, such as the production base in Shanghai where these transmissions are commonly found. This collaboration began with Roewe's goal to improve transmission efficiency. The structure of CVT allows for ultra-smooth gear shifts, providing a jerk-free driving experience while also being fuel-efficient. SAIC's localized production aims to control costs and ensure timely supply, though the core components are still imported. Owners report that these transmissions are durable and require simple daily maintenance, with regular oil changes being sufficient. If unusual noises occur, a visit to the 4S dealership for inspection is necessary. In fact, it's not just Roewe; other Chinese brands like Geely also use similar supply chains. However, Roewe has done well in matching and tuning, making the driving experience in models like the i5 or RX5 quite intuitive.
