the ground. This is the reason why American choppers sport long front forks for that straight-line stability. Equations (5.10) and (5.11) express the vehicle motion to steering angle, , when considering the static characteristic of the steering system.Comparing these equations with Eqns (3.12) and (3.13) Eqn (3.12) Eqn (3.13) shows that the front wheel cornering stiffness, K f, is replaced by eK f in Eqns (5.10) and (5.11).In other words, the vehicle response to steering wheel angle, , has the . United States Patent 3866946. You will do the opposite if you are more interested in handling around corners. Required fields are marked *. Found inside Page 99The flat plank machine ( Fig 3 ) can measure dynamic changes to camber angle and relaxation length . position of the tire and changing the angle of the plank , so that camber angle and steering angle can be computer - controlled . SAI is a diagnostic angle. WITH just two wheels and two sets of suspension, a motorcycles geometry is far less complex than that of a car. Wikipedia gives the formula for figuring this out, although you need to transpose some terms, you need to know the bike's dimensions, and you need to decide the radius of your turn.. Based on that formula, and assuming a bike with a head angle of 72, a . In the reverse steering configuration, the roll angle was the result of the integration of motorcycle speed and handlebar steering angle. The steering-angle sensor is based on Giant Magnetoresistance technology (GMR element) and provides an absolute steering-angle value over the complete steering-angle range (multi-turn sensor). Ride something like that much over walking speed and youll be introducing your face to the ground. Generally speaking (meaning there are exceptions) the greater the rake angle, the more stable the motorcycle is at higher speeds. This data PID can be used for electric power steering, intelligent headlights and even . To turn a motorcycle at slow speed, the most crucial element is to turn the handlebar in the direction you want to go. A trail can be thought of as a buffer zone in relation to the movements of the handlebars. 25 Rider Magazine Insider Podcast, Eddie Braun: Ep. Add me . Found inside Page 95If you increase speed or decrease the radius of your turn, your lean angle will get larger. Leaving aside the situation where two motorcycles have different wheelbase lengths and different rake angles, which would clearly produce . Rake angle, sometimes called caster angle, is the angle of the steering head (steering axis) from vertical, measured in degrees. To better understand this, visualize a motorcycle with 0 degrees of rake, with the forks straight up and down, perpendicular to the ground. This is the bible on the subject. Found inside Page 1360(e) A motorcycle rider has two steering control inputs, steering torque (or angle) and rider lean torque (or angle), although there is much evidence to suggest that rider leaning is a very weak control in comparison with steering torque In other words, rake is a measurement - in degrees - from the headstock of your motorcycle to a vertical line drawn through the front axle of your motorcycle.
