You can graph 4-link suspension geometry as well. Specifications are entered in the input page. Will be selected here and in the input page. 3-6 existed in the suspension geometry are ignored, the calculation results will deviate from the real value. Vertical spacing between upper and lower a-arm shafts, 10.84 (average at center of shaft) Upper a-arm length 8.25. Spindle height (balljoint centers) 11.875. And you can click on any instant center location, and the associated link mounting holes 255/45-17 tire rolling radius 12.67 (Kumho) Early C4 suspension measurements. Below, we define the important measurements that dictate the shape, fit and handling of a mountain bike, and explain how. Which hole combination generates this instant center location. A bike’s geometry is perhaps the most important aspect of its design. Calculation: -Adams uses hypotentous as its swing arm while we the horizotal distance,inorder to convert between the two we will use the front view angle: Triangle ABC: Fvsa length (horizontal) (AB)fvsl hypotenous (Ac)cos (fvsa angle)2914cos (5. You can point at any instant center location marker and the pointed location's statistics are listed, including Instant center location markers are shown for every possible combination of mounting holes, making it easy to instantly visualize all of the possible Your front suspension geometry is defined by the following six variables which are: OFFSET: Centerline of the top steering neck to the centerline of the top. The imaginary lines can be turned on and off as desired. Visualize how much the chassis and links have moved. Imaginary (dotted) lines also indicate the normal (zero travel) position of the links and their mounting holes, making it easy to Along with the movement of the chassis, the front link attachment points move, and the rear ones move correspondingly.Īlong with the visual depiction are calculations for the following:Ĭalculated data instantly updates automatically as the car moves. To provide isolation from high frequency. Vehicle travel is simulated by dragging the image with the mouse or with a scroll bar.Īs you drag the mouse (or the scroll bar), the car moves up and down in response. this requires the suspension geometry to be designed to resist squat, dive and roll of the vehicle body.
