Electric disk brake, caliper for the electric disk brake, motor/controller unit for the electric disk brake, and method for assembling the caliper for the electric disk brake
An electric disk brake that can be operated and inspected before being assembled and that can be assembled easily. A piston, a ball ramp mechanism, a differential reduction mechanism, and a pad wear compensation mechanism are integrated to form a piston unit. A motor, a resolver, and a drive controller are integrated to form a motor/controller unit. The piston unit is inserted into a cylinder of a caliper body, and the motor/controller unit is mounted on the caliper body to assemble an electric caliper. Before being incorporated into the electric caliper, the motor/controller unit can be operated and easily inspected for any defect by applying an electric current to the motor/controller unit.
