The Differential Lock Coil Spring functions by generating a controlled restoring force that influences engagement and disengagement movement. When an external force acts to activate the differential lock, the spring compresses and stores mechanical energy. As the activating force is reduced and removed, the stored energy is released, driving the return movement toward the initial position. This action supports controlled transition between locked and unlocked states by regulating how components shift relative to each other.Attributes:• Number of active coils is 2, and total number of coils is 4.• Provides consistent force for lock engagement.• Maintains alignment of locking components.• Generates restoring force to return components after lock engagement movement.Applications: The Differential Lock Coil Spring is used for providing restoring force between the differential case and sleeve bearing to control engagement and return movement during differential lock operation.
