The larger rear pulley is what we refer to as the Clutch Pulley (it’s on the right side in the simulator above). A CVT can get maximum power out of a … - Gates Snowmobile & ATV Belts The next article was found by Cajun, who is a moderator on atvquadsquad.com, and was referenced in his thread on that site called: CVT explained/ Tuning info U of Maine-this pdf goes a little more in depth to the theory and tuning aspects of the CVT. There is another type of CVT, known as a hydrostatic CVT, that uses variable-displacement pumps to vary the fluid flow into hydrostatic motors. At low engine speed, the plates of the front pulley are pushed apart by the tension of the belt as it forces itself between the plates. How does the clutch system work? By changing and maintaining the components inside the clutches, improved performance and drivability are pretty easy things to achieve. through the inner workings of a CVT's Primary clutch. The Rear (Clutch) Pulley. Automakers are using CVTs for several reasons. It takes two, baby. All snowmobiles have a clutch; you don’t have to worry about a stick shift though. The components are the drive (primary) clutch and the driven (secondary) clutch). This allows a CVT to deliver strong and seamless acceleration. The shift weights work in combination with the driven clutch spring to open and close the drive clutch. You only need to use your throttle and brake. Both the pulley-and-V-belt CVT and the toroidal CVT are examples of frictional CVTs, which work by varying the radius of the contact point between two rotating objects. Changing the spring should be the first step in adjusting clutch engagement and shifting performance. Your snowmobiles clutch is a form of continuously variable transmission (CVT), think about like an automatic car. Golf Cart Clutches. 4. (A second, less common, type of CVT uses a series of discs and rollers.) The drive (or primary) clutch … Pros of Using a CVT. The CVT (continuously variable transmission) drive system on the RZR is one area where you can see big performance gains with a few mods. CVT Clutch Tuning Basics - Part 2 Understanding the Fundamentals: ATV & UTV : There are two options for clutch optimization- A a scientific method, or B a not so scientific This design does away with gears entirely. The spring also plays a role in controlling the rate at which the CVT changes ratio, specifically how much engine rpm is required to upshift. How it works The CVT works upon the ratio of the diameter of the front and rear drive belt pulleys. Golf cart clutches or the CVT (Continuously Variable Transmission) is comprised of two different clutches connected together by a thick drive belt. Instead of two gears, there’s two pulleys connected by a belt. It contains a centrifugal clutch, which allows the vehicle to idle without moving once the engine speed drops below 3000RPM. One sheave is fixed to the shaft and does not move while the other one moves in and out, forcing the belt to a higher or lower position in the clutch. This design does away with gears entirely. So let’s see how do snowmobile clutches work. I am using STM's Rage 4 primary cam design as a basis for this description but it should apply to most primarys with adjustable weights.
