Seat Recliner Torsion Spring

What are the characteristics of torsion springs:Torsion springs are a type of elastic element whose main characteristics are as follows:1. torsion springs are able to withstand large torsional forces: torsion springs are mainly subjected to torsion and torque in their work, so their design structure needs to meet the need for larger torsional forces, making them able to twist steadily without fatigue deformation or loss of elasticity.2. Rich in composition: torsion springs have a wide variety of compositions, from simple cylindrical to very complex oval, square, hook and other springs of different shapes and sizes.
