Carauto window regulator used mostly by the motor, reducer, lead rope, guide plate, glass, mounting brackets and other components. Guide rope for the material or production process in different ways, they wheeled into rope, flexible shaft type and plastic belt of three electric window regulator. The first two are used as a guide wire rope, the latter is used as a guide with a plastic rope. To the widespread use of the rope wheel electric window regulator, for example, by the motor, reducer, steel wire rope, guide plate and glass, the composition of mounting brackets and other components, install glass doors on the mounting brackets fixed to the glass, glass guide parallel plate slot and the wire rope guide. Open the motor, driven by a motor reducer output power, pulling rope mobile glass installation bracket, forcing the glass doors and windows to make upward or downward linear motion. The plastic electric window regulator with the lead rope is plastic belt, belt with holes, to move and locate plastic zone, control the movements of the glass doors and windows. Electric window regulator is the key structure of motor and reducer, both of which are assembled into one, in which reversible motor with permanent magnet DC motor, motor around to different groups within the magnetic coil, can do through the control switch is transferred and the reverse, that can control up or down the glass doors and windows. Motor is controlled by a double-switch button, with up, down, off the three working state, the switch does not control automatically stops at the "off" position. Control circuit with master switch (central control) and sub-switch, two parallel lines. The total switch from the drivers to control the opening and closing all the doors and windows of glass, while the inside door handle on the sub-switch controlled by the crew were all glass doors and windows open and close, the operation is very convenient.
