Operating Principle Of Window Regulator

The window regulator is a device that allows the side windows to be rolled up and down. There are many types of these mechanisms. They are different in design and operation. Therefore, it is necessary to be familiar with the window lifting mechanism in more detail.

Depending on the type of drive, there are manual and power window regulators as described above. Manual operation is carried out with the help of a special handle on the door card, which looks like an oar. With the effort of one hand, the window moves in the right direction. In the electric elevator, the motor replaces the power of the hand. To scroll the window up and down, simply press the appropriate button. In addition, the electronics will do all the work by themselves - the signal will be transmitted to the commutation motor, which will begin to move on the track. Usually this switch is located near the door handle. Depending on the configuration of the car, there are two or four window regulators.

The driving gear (or gear motor) combines the motor, gear and worm gear in its operation, which are made in the form of a single unit. This mechanism is necessary to generate forces that will raise and lower windows. Due to the use of worm gear, the window will not open accidentally. The worm gear is designed so that rotation is transmitted in only one direction - from the worm to the wheel. If you try to rotate in the opposite direction, the transmission will be blocked.

Through the lifting mechanism, the window can be lifted directly. The design of the mechanism can be very different, so there are graded window regulators. They can be gears and racks, cables and levers. Cable and lever lifting mechanism are the most popular among manufacturers.

The cable window regulator is a flexible element (chain, cable, toothed belt) that is tensioned between multiple rollers in the door. The flexible element is powered by pulses from the drive drum. When the drum rotates, one branch of the flexible element is wound and the second branch is wound. The element itself begins to move gradually. The flexible element is connected to the window through a plate. The main advantage that distinguishes the cable regulator is its high maintainability.
