DRAG REDUCING CALIPER FOR REDUCING WEAR OF PAD BY DRAG AND CONTROL METHOD THEREOF

摘要

An objective of the present invention is to provide a means for suppressing wear of a pad by drag when an automobile starts after braking to reduce pad dust and remove a cause of environmental pollution. According to the present invention, a control means of a caliper suppresses wear of a pad by drag when an automobile starts after braking to reduce pad dust. An inter-return spring is installed between an inner pad and a piston embedded in a caliper for a brake of the automobile. The inter-return spring is provided in a bottom plate and a bent part. The bottom plate is fixed on the inner pad. The bent part supports a side wall in the piston to be fixed while maintaining elasticity and is installed to move backward with the inner pad when the piston moves backward. An outer return spring of an elastic material is installed between a finger unit of the caliper and an outer pad to move backward with the outer pad when the finger unit moves backward to reduce wear of the pad by drag when the automobile starts after braking.;COPYRIGHT KIPO 2017
