What are shock absorber ratios?
A: The numbers in a shock ratio refer to the amount of pressure needed to compress and extend (also known as rebound) a shock. The first number is compression; the second is rebound. Take a 50/50 shock, for example. It takes the same amount of pressure to compress and rebound this shock.
What is the price of an ATV Spring?
It depends on your vehicle weight and the motion ratio you need and also the suspension play you need. For vehicle weight of 200 and play of 8 8inches you might need spring rate of 130 to 150 kg per inch.
How do you calculate motion ratio?
The motion ratio can be approximated by taking a few measurements under the car.
- d1 is the distance from the control arm inner pivot point to the spring centerline.
- d2 is the distance from the control arm inner pivot point to the outer ball joint.
- motion ratio = d1 / d2.
How do you calculate installation ratio?
If your readings are all similar for the installation ratio then you can calculate the installation ratio for your car by simply adding together all of the values you have written down for installation ratio in the table and then divide that number by the amount of measurements you have taken.
What is the difference between spring rate and wheel rate?
Wheel Rate is basically the Spring Rate but measured at the wheel instead of the where the spring attaches to the linkage. It is basically the Spring Rate multiplied by the motion ratio squared. The motion ratio is the ratio between how much the spring is compressed compared to how much the wheel is actually moved.
What is spring motion ratio?
The spring motion ratio (MRSp) is defined as the ratio of the spring displacement (dB) to the wheel displacement (dA), as shown in Equation 4 below. Since the arm rotates around a common pivot, the length between the pivot and the points of interest also determine the motion ratio.
How do you calculate movement ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
What is installation ratio?
An installation ratio is the ratio between how much the spring and damper moves in relation to how far the wheel and tyre move. It therefore determines the amount of deflection that the spring and damper and anti-roll bar will experience at any displacement of the wheel and tyre.
What is wheel motion ratio?
The motion ratio is the ratio between how much the spring is compressed compared to how much the wheel is actually moved. For example if the spring only compresses 0.6 inches when the wheel is moved 1 inch, that would be a . 6 motion ratio.
