Abstract
An automobile wiper motor comprises a motor casing, a magnetic shoe assembly attached to the inner wall of the casing, an armature component arranged in the motor casing, a shaft shoulder sleeve for sealing the motor casing and a wiper reduction box connected at the output end of the armature component. The armature component comprises a rotor iron core arranged in the motor casing, a winding wound on the rotor iron core and a commutator arranged on the rotor iron core. The automobile wiper motor is characterized in that the wiper reduction box comprises a box body, a cavity is arranged in the middle of the box body, a worm gear and a worm which are connected with the rotor iron core through a clamp spring are arranged in the cavity, and a limit steel ball is arranged at the top of a worm of a worm gear and worm speed transmitter. When being operated, the automobile wiper motor is meshed stably, can reduce emission of noise, and improves quality.
