Dynamic, elastic deformation occurs for compression spring (18), spring (18), stores the contact surface of elastic potential energy, snap ring (17) and piston (14)
Between without relative motion.When releasing braking operation, motor (10) drives driven gear (19) to rotate backward, now, one-way clutch
(8) separate, swingle (2) is in free state, the elastic potential energy release of spring (18) storage, makes piston (14) and braking clamp body
(1) relative motion, drive and reversely rotated under elastic potential energy effect of the swingle (2) in spring (18), all elements recover just
Beginning position.
When friction plate (15) wears, after thickness is thinning, during braking operation, motor (10) by gear mechanism drive unidirectionally from
Clutch (8) combines, and driving swingle (2) rotates, and promotes piston (14) and braking clamp body (1) relative motion, the bullet of spring (18)
Property deflection reach maximum, snap ring (17) is close to when on the step surface of left side, and because friction plate (15) wears, braking effect is not
Good, now motor (10) drives swingle (2) to be rotated further by the one-way clutch (8) of combination, i.e. piston (14) and braking
Caliper (1) continues relative motion, and therefore, spring (18) keeps maximum flexibility deflection, and piston (14) overcomes and snap ring (17)
Between frictional force, be engaged with new contact surface with snap ring (17).When releasing braking, motor (10) drives gear mechanism anti-
Turn, one-way clutch (8) separation, the elastic potential energy release of spring (18), make piston (14) and braking clamp body (1) relative motion,
Swingle (2) rotation is driven, now snap ring (17) and piston (14) coordinate positioning with new contact surface, and return displacement is still
