Double torsion spring is divided into outer and inner twisted double torsion spring, is a special kind of torsion spring, which in the process of movement to change the direction of the torsion spring, to generate power or resistance, so as to realize the adjustment of the control force.
Each circle or close around or is separated from the surrounding, in order to "(spring and torsion load axes at right angles). At the end of the spring can be wound into a hooked or straight torsion arm.
Double torsion spring is composed of a set of right hand rotation spring coil and a group of left hand rotation spring ring. Is not dense body part of the coil winding is in between, and the spring coil parallel spinning. The need for a separate design of the part, the torque value of two ends of the spring ring and.
