Throttle Updates
| The throttle produced in EID 101 worked, and is a useful tool for calibrating the engine for a convolution throttle, but posed some issues. It is difficult to repair and maintain, and could be optimized in some other aspects as well. So working off of a design change from Spyros Korsanos, I am designing a new throttle which is a bit more user friendly. |
Throttle D6 and D7
| In these stages we made the big jump of place the springs outside the throttle body in order to allow for easier maintenance of the springs. Previously they were sealed inside the throttle in a tiny, and consequentially limiting, channel and fixed by pressed fitted pins. The press fits made the springs hard to change, and the channel limited us on what springs we could use, so Spyros suggested moving the springs outside the throttle. |
D6
An actuator interacts with the sliding plate via pins going through slots in the top plate.
D7
Eliminated some unnecessary parts and decided that the cable which actuates the actuator could be simply wrapped around the actuator and cable clamped. This eliminates limitations which were posed by the barrel adjuster and made for a simpler actuator.
D8
Ultimately I reverted back to D5, which was the throttle I ended up with last semester in the EID 101 section. This design proved to be much easier to manufacture and with some adjustments on the channel dimensions, it was easily modified to handle a wider variety of spring. Also by cutting the sliding plate in half, the size is greatly reduced.
