Throttle pedal with minor but very important changes · 模型 317398
I added PTFE washers and two M 2,5x8 bolts to secure spring. Also I strongly advice adding simple pressure sensor under the spring or directly under the placement of driver foot. In case of spring failure or loose of pressure from the driver foot it can send signal to car onboard computer to cut off feed from potentiometer to prevent uncontrollable speeding. Its to late to put changes but flat spring can be changed to much more safe gas spring. Which is less prone to catastrophic failure. Rest is the same: 3 basic parts of pedal can be machined from materials like steel or aluminium, or can be made from plastic with high % of glass fibre by injection molding (for example PA 66 - 30% or 40% glass fibre reinforced) . In assembly flat spring is pushing upwards pedal to give tension, secure "0" position when it's not used, and to give nice feel under the foot when pedal is pressed. 40 degrees of rotation are assured by steel rood and cut-out in pedal main body which allows for only 40 degrees of movement. Cut out can have sleeve from PTFE for low friction. Sensor assembly is independent from pedal assembly, and is hold in place by 2 M5x30 bolts. Potentiometer takes reading directly from steel axis on which pedal is pivoting, axis have simple sliding bearings (brass in bearings can be replaced by PTFE).
