Tilting Three Wheeled Electric Car

I’m a big fan of electric cars.  Electric motors have some major advantages over internal combustion engines: 100% torque from 0 RPM – immediate power off the line Linear torque delivery – no “lumpy” torque delivery like turbo engines or

Reference Library

How do you learn how to design and build a car from scratch? You have to become an autodidact and learn everything you can about the subject. I’ve personally been amassing a design library to help me along with this project.

Wiring

Two of the main design goals of the car are simplicity and lightness. Wiring harnesses can become extremely complex and because they are made of dense metals like copper, they can also become extremely heavy. The wiring harness for the average

Tilting System

Camber Thrust Tilting the wheels of a car so that they lean into a corner (like on a motorcycle) is most beneficial because it creates “camber thrust.” Tires can develop cornering force in two ways: slip angle and camber thrust. Slip

Suspension

Suspension Geometry There are a number of different types of suspension geometries: live axel, swing axel, multi-link, double wishbone, MacPherson, etc. The most easily-adjustable suspension type is the multi-link geometry. It allows the highest amount of control over everything from kinematic

Street Legal Requirements

Because the car will be a 3-wheeler, it will technically be classified as a motorcycle for safety purposes. This greatly reduces the amount of legally-required equipment, thereby following our main design principles of simplifying and adding lightness. California CHP Since

Steering System

Steering Ratio Ackermann Steering Geometry As your car turns, the outer wheels are further from the center of the steering circle than the inner wheels. This causes your wheels to follow two separate paths with two separate circle radii. An Ackermann steering geometry

Motors & Gearing

One of my main design goals is to keep the mass of the car as low as possible. This means selecting motors that have the most power per unit of weight. I’m planning to run three motors on the car
