Why can’t a CVT transmission have a chain instead of a belt ?

As someone curious about the design limitations of CVT transmissions, I want to understand the reasons behind the unavailability of chains as an alternative to belts. By exploring the factors that prevent the use of chains in CVT transmissions, I can gain insights into the technical considerations and limitations that make belts the preferred choice in this type of transmission.

CVT (Continuously Variable Transmission) systems use belts instead of chains for several reasons, including design considerations and performance characteristics. Here are some factors that contribute to the preference for belts in CVT transmissions:

  1. Flexibility and adaptability: Belts are more flexible than chains, allowing them to better conform to the variable-diameter pulleys used in CVT systems. The ability to adapt to different pulley sizes is crucial for the continuously variable gear ratios in CVTs.
  2. Noise and vibration: Belts generally produce less noise and vibration compared to chains. This is beneficial for overall comfort and smoothness of operation, which is a desirable characteristic in passenger vehicles.
  3. Weight and space considerations: Belts are typically lighter and more compact than chains, allowing for more efficient packaging in the limited space of a vehicle’s transmission system. Lighter components can contribute to improved fuel efficiency and performance.
  4. Efficiency and friction: Belts offer reduced frictional losses compared to chains, leading to improved efficiency. The lower friction helps optimize power transfer and minimize energy losses, which is important for fuel economy and performance.
  5. Cost and complexity: Belts are generally less expensive and simpler to manufacture and maintain compared to chains. They require fewer components and can be replaced more easily during maintenance or repair, resulting in reduced costs.
  6. Lubrication requirements: Chains in a transmission system typically require regular lubrication to ensure smooth operation and longevity. Belts, on the other hand, operate dry, eliminating the need for lubrication and reducing maintenance requirements.

While chains have their advantages in certain applications, such as higher torque applications or off-road vehicles, CVTs primarily prioritize smoothness, efficiency, and cost-effectiveness. Belts have been found to better meet these requirements in most passenger vehicle CVT applications.

It’s worth noting that the use of chains in CVTs is not entirely absent, as there are some specialized CVT designs that incorporate chains. However, these designs are less common and typically used in specific applications where their advantages outweigh the benefits provided by belts.

Overall, the choice between belts and chains in a CVT system depends on various factors, including the specific design goals, performance requirements, and cost considerations of the transmission system.
