How to Find a CVT Gearbox with 19:2 Gear Ratios
When working on a project that requires a CVT (Continuously Variable Transmission) gearbox with a specific gear ratio, it can be challenging to locate an appropriate dealer or manufacturer. These specialized components are often not readily available from traditional automotive dealerships. However, there are several strategies and resources that can help you achieve your project's gear ratio requirements, including finding spare parts from related machinery such as snowmobiles, quads, and ATVs. This article will guide you through the process of sourcing a CVT gearbox with a 19:2 gear ratio.
How to Locate a CVT Gearbox Dealer
To start your search, it's crucial to understand that a dedicated CVT gearbox dealer might not be the first option for customization or sourcing unique gear ratios. Instead, you should look for manufacturers or suppliers that specialize in CVT systems. The websites of automotive manufacturers who use CVT in their vehicles can provide valuable information on the specific specifications and components used. By examining these sites, you may find detailed gearbox specifications that could be suitable for your project.
One example from a few years ago involved a Dutch motorcycle project powered by a Smart 3-cylinder CDI engine. The engine was paired with a CVT gearbox taken from a snowmobile. This incident highlights the possibility of sourcing a gearbox from different types of vehicles, such as snowmobiles, quads, and ATVs.
Research Alternative Manufacturers
When searching for a functional gearbox that can meet or exceed a 19:2 gear ratio, consider looking into manufacturers that specialize in snowmobiles, quads, and ATVs. These types of vehicles often use CVT gearboxes that can provide the necessary torque and range. By focusing on these manufacturers, you can often find gearboxes that are more suitable for high-performance or specialized projects.
Here are some online resources to help you start your search:
SNOWMOBILE PARTS MANUFACTURERS: Websites for snowmobile parts manufacturers can provide information on the types of CVT gearboxes used, which are often available for purchase or can be adapted for use in your project. QUAD/ATV MANUFACTURERS: Similar to snowmobile parts manufacturers, quad and ATV manufacturers can offer the necessary gearboxes for your project. DIY COMMUNITIES AND FORUMS: Engaging with online communities dedicated to automotive projects or gearheads can provide recommendations and potentially even forums where people share their experiences with acquiring specific gearboxes.Adapting and Customizing Gearboxes
While finding an exact match for your desired 19:2 gear ratio may be difficult, adapting a similar gearbox is often possible. Some manufacturers offer customization options, or you can work with a mechanical engineer to adjust the gearbox to fit your specific needs. Customization options may include:
Adjusting Curve Performance: Some CVT systems allow for customization of the curve performance, which can impact the gear ratio within a certain range. Contacting the manufacturer to discuss custom specifications could lead to a gearbox that meets your needs. Adding Custom Components: Adding or modifying components within the CVT system can help achieve the desired gear ratio. This process often requires detailed knowledge and specialized tools, so consulting with experts in the field is recommended.For those considering DIY modifications, certain kits and components may be available for some CVT gearboxes. Researching online forums and instructional videos can provide valuable insights into the feasibility of these modifications.
Conclusion
Locating a CVT gearbox with a 19:2 gear ratio can be a complex task, but through a combination of online research, utilizing alternative manufacturers, and possibly adapting or customizing existing gearboxes, your project can be made to fit your specific requirements. By taking a strategic approach and leveraging the resources available, you can find the right CVT gearbox to power your project.
