Similar to progressive rate springs, variable pitch springs are different than regular compression springs that are designed to have a linear spring rate.
What is a variable spring rate?
The variable spring rate is the spring rate increases with the spring deflection. The spring rate is not constant or linear.
Variable pitch springs can have multiple rates or, while the spring is compressing, they can have a progressively increasing or decreasing spring rate. By “varying” the pitch, or the center to center distance between the coils. By lessening the amount of active energy-absorbing coils as they become inactive and no longer absorb energy during compression. Because some of the coils close up faster than the others, the spring, in turn, becomes stiffer, and the rate increases.
Variable pitch springs in the automotive industry
Stanley Spring offers variable pitch springs to many customers in the automotive industry, as the springs provide flexibility and will change based on the load balance. Many race cars and motorcycles use variable pitch springs to allow for better handling as well as shock absorbers.
Stanley Spring is continually looking for efficiencies through innovation for our customers. We’re proud to use the latest technology to provide variable pitch springs that allow for increasingly greater ranges between rates. We have experienced team members with the expertise to collaborate with any customer to design variable pitch springs that will fill any need and meet any requirement.
Thank you very much,
If all the vendors that we have worked like you, the things will be very practical,
