Throttle Pedal Tray

As Brakes System Lead, my objective this year was to change the throttle pedal tray and tailor it for our new EV car. Linear potentiometers were required as position sensors for the throttle pedal to replace the function of the previous throttle linkage and wire. For this, linear potentiometers from Texense were chosen due to their size, performance, and price range after having done research on different brands. The linear potentiometers were then cadded in SolidWorks and meticulously positioned on the throttle pedal tray. For this the tabs' positions was calculated and changed. Respective bolt and nut sizes were chosen and put in the CAD to fully fasten the linear potentiometers. The two transparent circles at one end of the potentiometer were cadded to indicate the mechanical travel points for pedal travel. My other objective was to bring the throttle back to 0% travel (initial position) after the driver released the pedal. This was achieved by putting a torsion spring on each side of the pedal. The pedal was designed to have a hole to house one end of the springs and the linear potentiometers at their respective locations. The pedal tabs were designed to accommodate the springs and keep them steady at each of the pedal by adding rectangular tophats that cleared the bolts that attached the tray to the floor of the car. The size of the tray and the number and position of tabs required to fasten the other ends of the springs, linear potentiometers, and pedal were chosen with respect to the maximum footprint allowed by the Chassis template of this year's car.
