What is Steering: Definition and 65 Discussions

Steering is a system of components, linkages, etc. which allows any vehicle (car, motorcycle, bicycle) to follow the desired course. An exception is the case of rail transport by which rail tracks combined together with railroad switches (and also known as 'points' in British English) provide the steering function. The primary purpose of the steering system is to allow the driver to guide the vehicle.

    Auto/Motor Design to 3D print RC car - Steering

    I am planning to design an RC car to 3D print it and have some fun. It will mostly be a learning experience with the by-product of having a hopefully fun RC car by the end of it. That will probably force some decisions that might be overengineered and negatively impact performance but building...

    Is this way of steering possible?

    I was wondering... Let's say we have a square platform with 4 wheels at corners placed on dirt and let's have left side wheels fixed straight and right side wheels are steerable so that when rear right goes in then front right goes out, would this way of steering work? What's your thoughts?

    I Realistic steering wheel angle when car follows points along a path

    Good morning , I managed to simplify the physics of my car with only the centrifugal and traction forces. If I'm in control of it, the realism is acceptable for a city builder. On the other hand, I encounter a problem when the car follows an array of points. The path of the car on my graph...

    I Steering a Car: Investigating the Forces of Rotation

    In a car we turn the wheels to steer. The wheels however are spinning about their axis of rotation when the car is in motion. Does the revolving motion of the wheels cause a force that opposes trying to rotate the wheels around the other axis to steer? How much opposition is created? Here's...
