Supercharger Pulley Systems: A Gripping Tale of ZPE's Patents

When it comes to the world of supercharger pulley systems, there's one name that stands out: ZPE. Known for their innovative designs and cutting-edge technology, ZPE has a range of patents that have revolutionized the industry. But what exactly do these patents cover, and how do they differ from one another? Buckle up, because we're about to take a deep dive into the world of ZPE's patents, and trust me, it's going to be a wild ride!

The Griptec Micro Series

Let's start with the Griptec Micro series. If you've ever taken a look at a Griptec Pulley, you might have noticed a series of letters and numbers following the phrase "Griptec micro". This isn't just a random assortment of characters, but a reference to the specific patent that the pulley's grip technology is based on. For example, if you see "Griptec micro L3", that means the pulley's grip technology is based on Patent 10655723 or 159421637.

But what's the difference between these patents? Well, each one corresponds to a different level of grip on the pulleys. Here's a quick rundown:

• W2 corresponds to Patent 8931156
• L2 corresponds to Patent 10655723, 159421637, or 9421637
• L2V corresponds to Patent 10655723, 159421637, or 9421637
• L3 corresponds to Patent 10655723 or 159421637
• L3V corresponds to Patent 10655723 or 159421637
• L3V-A corresponds to Patent 10655723
• L3V-B corresponds to Patent 10655723

Now, you might be wondering, "What's the difference between these grip levels?" Well, that's where things get interesting...

Comparing the Patents

Let's start with Patent 8931156, which corresponds to the W2 grip level. This patent covers a pulley assembly that includes a body, a shaft mount, and a series of bolts that attach the body to the shaft mount. The shaft mount is mountable to a shaft of a supercharger, and the body is attachable to the shaft mount with the bolts. The body of the pulley assembly has a pattern of friction lines for increasing the frictional forces between the outer surface of the body of the pulley assembly and the belt driving the pulley. The friction lines are formed by applying particulate matter to the outer surface of the body of the pulley assembly and fusing the applied particulate matter to the outer surface by heating the outer surface and the particulate matter. The heat is generated by a laser beam that traces a desired pattern of friction lines. This increased friction reduces slippage between a belt and the pulley, mitigating noise.

Next up, we have Patents 10655723 and 159421637, which correspond to the L2, L2V, L3, L3V, L3V-A, and L3V-B grip levels. These patents cover a pulley for transmitting rotational motion between first and second rotating shafts with a belt on an automobile engine. The pulley comprises a body and a laser-infused friction material. The body has a cylindrical central hole for receiving the firstrotating shaft and mounting the body onto the first rotating shaft on the automobile engine. The laser-infused friction material is bonded to an outer surface of the groove on the body. This material is configured into a pattern on the outer surface of the groove, increasing the coefficient of friction and reducing slip with another material such as a belt.

Lastly, we have Patent 9421637, which corresponds to the L2 and L2V grip levels. This patent covers a method of fabricating a pulley for transmitting rotational motion between first and second rotating shafts with a belt on an automobile engine. The method involves forming a body with a cylindrical central hole for receiving the first rotating shaft, covering an outer surface of the groove with a powder material, and selectively applying heat from a laser beam to the powder material and the outer surface of the groove to fuse the powder material to the outer surface of the groove. The fused powder material provides a surface texture to increase its coefficient of friction and reduce slip with another material such as a belt.

FAQ

Q: What is a GripTec pulley?
A: A GripTec Pulley is a high-performance pulley for superchargers. Its unique design reduces belt slippage, a common issue in supercharger systems. This results in more consistent power, improved performance, and longer system lifespan. It's customizable and compatible with various supercharger brands.

Q: What is the difference between the various Griptec Pulley grip levels?
A: Each grip level corresponds to a different ZPE patent, which covers a specific type of grip technology. The higher the grip level, the more advanced the grip technology.

Q: What is the advantage of a higher grip level?
A: A higher grip level means less slippage between the belt and the pulley, which can improve performance and reduce noise.

Q: Can I upgrade my existing Griptec Pulley to a higher grip level?
A: Yes, you can upgrade your existing Griptec Pulley to a higher grip level by purchasing a new pulley with the desired grip level.

Q: What is the benefit of the laser-infused friction material in theL2, L2V, L3, L3V, L3V-A, and L3V-B grip levels?
A: The laser-infused friction material increases the coefficient of friction and reduces slip with another material such as a belt. This can improve performance and reduce noise.

Q: What vehicles are compatible with Griptec Pulleys?
A: Griptec Pulleys are compatible with a wide range of vehicles, including the Corvette ZR1, Z06, Camaro, GT500 Mustang, the Hellcats and CTS-V along with many aftermarket blowers.
