Project Overview

The 3 Speed Transmission is a performance bolt on to existing small engine Honda clones. Since a transmission has yet to be introduced, these engines are limited to single speed gearing. Which ultimately restricts the performance of the small engine vehicle. It’s a trade-off, high top speed and slow acceleration, or low top speed and fast acceleration; with a transmission there’s no need to choose. Similar to a manual transmission in a car, an input, counter, and output shaft are used with a constant mesh transmission to create different gear ratios.

Proof of Concept

The main industry this product impacts would be child-sized and cheap recreational vehicles. The main torque converter used in this industry are less effective CVT transmissions that use weighted rollers to chain the gear ratios. This new, gear driven, transmission would revolutionize the application of small displacement engines. The main concern for this transmission would be cost. These engines as a whole is quite inexpensive as a whole, so manufacturing cost will be essential to our selling point. These engines have a wide range of applications, so even existing products will be potential consumers.

Meet the Team

Carlos Bean

Carlos is a senior engineering student at the University of Nevada, Reno, originally from Las Vegas, Nevada. The most challenging engineering project he worked on was building the 3D Printer. Needing constant testing and improvements, it really tested Carlos’ abilities. Carlos has learned to apply his engineering education to his everyday engineering projects. He also learned the business and entrepreneurship skills from Make48 and his engineering entrepreneurship class. Carlos’ proudest creation was his homemade drift trike powered by a 197cc Honda clone engine. With a 6:1 gear ratio, it was obvious the gearing was too high to run at cruising speeds. Since then, Carlos has been interested in creating the first bolt on transmission for these engines. Goals now are to graduate, design and build race cars. Carlos wants to restore his Camaro, and build the perfect high power pro-touring race car.

 

 

 

Jose Carrillo

Jose is graduating in the spring with a mechanical engineering degree. He’s originally from Las Vegas, Nevada and moved to Reno in 2015 for college. Some of his short term goals include graduating and doing well in this class. Some of his long term goals include going into aviation and aeronautical industry. One of the most challenging engineering project that Jose encountered was the statics bridge. It wasn’t hard to build but hard to calculate all the forces beforehand to make sure it could withstand the weight. A proud accomplishment of jose is the fidget spinner. This was because it was before fidget spinners took off like crazy, so it was like we started the trend.

 

 


Sierra Fulton

Sierra is originally from South Lake Tahoe and came to the University of Nevada, Reno in 2014 to study Business Management. After a year in business she switch into engineering. As an engineering student, Sierra was exposed to a number of projects that have challenged her and taught her a number of new skills. The most challenging project she has worked on was the hovercraft project assigned during her first semester. During the project, two of her teammates abandoned the team leaving the rest of the team short handed. The work the remaining members had to put into the project was extensive, but they were able to pull off a unique and successful end product. Outside of school, Sierra is a part-time manager at Beach Hut Deli and will be starting an internship working for EM Research towards the end of November. After graduating Sierra hopes to explore more engineering opportunities outside of Nevada or possibly outside of the United States.

 

 

 

Tyler Rupley

Tyler is a senior mechanical engineering student at the University of Nevada. Tyler graduated high school in 2011 and started an economics degree at UNR. After two years, Tyler started working full time for an insurance company. Tyler decided to come back to school in 2015 to pursue a mechanical engineering degree. Tyler has since been a part of ARLISS and NSat, autonomous drone clubs at unr, and continues to work on his street bike.

 

 

 

 

 

Joshua Wilding

Joshua is also a senior  at UNR who was born and raised in Reno, Nevada. Graduating in the spring with a bachelor’s degree in mechanical engineering as well as an associates degree in business administration. Along with school, Joshua takes on a full-time lead position at GSR and oversees ten employees. Engineering accomplishments include hovercraft, static bridge, and CSWA certification, with the freshman year hovercraft project being the most challenging engineering project. The hovercraft and static bridge, along with several group projects, have developed problem solving skills that will carry over to a professional career. Short-term future plans are to build a pulse jet, other short term goals involve leaving GSR and starting an engineering internship in an attempt to transfer into a more serious engineering job. Long-term plans involve getting a successful job with an engineering firm and trying to engineer a better future. Also engineering an off the grid RV to live in full time and travel across the US taking up different engineering related jobs.
