By inclining the steering axis inward (away from the wheel), it causes the spindle to rise and fall as the wheels are turned in one direction or the other. Because the tire cannot be forced into the ground as the spindle travels in an arc, the tire/wheel assembly raises the suspension and thus causes the tire/wheel assembly to seek the low ...
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of the vehicle to changes in steering angle associated with changes in lateral acceleration. This sensitivity is defined for a level road for a given steady state operating condition by the Society of Automotive Engineers (SAE) in document J670 [ 1 ] and by the ...
Double Wishbone Suspension. In automotive suspension, a steering knuckle or upright is that part which contains the wheel hub or spindle, and attaches to the suspension and steering components. [1] The terms spindle and hub are sometimes used interchangeably with steering knuckle, but refer to different parts.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. [1] Suspension systems must support both road holding/handling and ride quality, [2] which are at odds with each other. The tuning of suspensions involves finding the right compromise.
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle The caster angle [ 1 ] or castor angle [ 2 ] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car , motorcycle ...
A cyclist steering a bicycle by turning the handlebar and leaning. Steering is the control of the direction of motion [1] or the components that enable its control. [2] Steering is achieved through various arrangements, among them ailerons for airplanes, rudders for boats, cylic tilting of rotors for helicopters, [3] and many more.
Spindles or uprights - Jaguar left and Holden Gemini right The wheel spindle in the illustration is colored red. In an automobile, the wheel spindle, sometimes called simply the spindle, is the part of the suspension system that carries the hub for the wheel and attaches to the upper and lower control arms.
The steering pivot points [clarification needed] are joined by a rigid bar called the tie rod, which can also be part of the steering mechanism, in the form of a rack and pinion for instance. With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.
