The chevron spring generally has three plates: upper, middle, and lower. The plates are vulcanized together with rubber in a “V” chevron shape, and are equally spaced. The chevron spring functions as a damper for the primary suspension and is installed between the axle box and bogie.
TEDRAIL can design different varieties of chevron springs with different dimensions, installation angles, and mechanical properties.
We utilize FEA analysis in order to find the optimal metal combining low weight and ability to meet performance requirements.
Our structural design maximizes service lifetime, which can be more than 10 years.
TEDRAIL's rubber formulation ensures low creep of 15-20% over the lifetime of the product, and we will make a lifetime creep prediction to compensate for the compression of the rubber.
We evaluate our products through various tests including static test, dynamic test, high and low temperature test, aging test, fatigue test, and creep test.
