generally used sheave lifter electric current is a motor, speed reducer, the guidewire, guide plate, a glass mounting brackets and other components. It is a lifting device of an automobile window glass, the main points of the manual electric window lifter lifter two categories. The general use push-button electric lift mode and electric window regulator. A main switch drivers, controls the opening and closing all the doors of glass, and a door handle on the inside of each sub-control switches are opened and closed by an occupant of the respective glazing, the operation is very convenient.
1. Structure and working principle
Most current electric lifter is a motor, speed reducer, the guidewire, guide plate, a glass mounting brackets and other components. Depending on the material making guidewires or different process embodiment, it is divided into sheave, and plastic with flexible shaft type power type three lifter. The first two species are used as the wire rope guide rope, the latter as a plastic tape guidewire.
When mounted on a glass window glass is fixed to the mounting bracket, glass and wire rope guide groove parallel to the guide plate. Turns on the motor, driven by the motor reducer output power, pulling rope mounting bracket moving glass, glass doors forceGlass for linear motion up or lowered. The plastic tape electric window lifter guidewire is plastic tape, perforated tape, for moving and positioning the plastic strip, control the movements of the window glass.
The key structure of the electric window regulator
is an electric motor and a reducer, both of which are integrally assembled, wherein the motor using a permanent magnet reversible DC motor, there are two different winding direction of the field coil of the motor, by controlling the switching of the forward and reverse do, that can control the rise or fall of the glazing.
The motor is a double-button control switch with up, down, off the three working condition, automatically stop at the closed position when the switch is not manipulated. Actuating the main switch circuit and sub-switch is provided, the two parallel lines. A main switch drivers, controls the opening and closing all the doors of glass, and a door handle on the inside of each sub-control switches are opened and closed by an occupant of the respective glazing, the operation is very convenient.
generally by actuating (control rocker or electric system), a transmission mechanism (gear, a plate or a rack, a gear engaging mechanism flexible shaft), a glass elevating mechanism (the lift arm, movement of the carriage), glass support mechanism (glass bracket) and the detent spring, a spring balance. Wherein the balance spring to the balance of gravity of the glass, to reduce operating force; and a pinion gear mounted between the bearing seat for the detent spring anchorage glass, to ensure its stay in the desired position.
2. The lifter Category
1. The single-arm type window regulator
The composition of the glass bracket arm, balance spring, fan.
2. The lifter arm
which is cantilevered support structure and the gear teeth plate mechanism, so that a large working resistance. Its transmission mechanism is a plate gear teeth, gear transmission, in addition to the main gear member are plate structure, easy processing, low cost, more common on domestic vehicles.
3. The single-arm window regulator
It is the structural characteristics of only one lifting arm, the simplest structure, but because of the relative position between the lift arm and the support point glassy heart often changes, will produce lifter is inclined, catching, the configuration only applies to a case where both sides of the glass parallel to the straight edge.
4. The glass lifter arms
It is a characteristic structure having two lifting arms, by the arrangement is divided into two arms parallel arms and the cross arm lifter lifter compared with single-arm type lifter, the lifter arms glass itself can ensure that the glass parallel movements, lifting force is relatively large. Wherein the cross arm window lifter supported large width, it is relatively stable movement, is generally adopted. Parallel arm lifter structure is relatively simple, compact, but due to the small width of the support, the larger work load changes, and thus movement stability than the former.
The sheave lifter
It is composed of the pinion gear, the sector gear, rope, carriage movement, pulley, pulley, gear engagement plate seat.
The drive pulley fixedly connected to the sector gear, thereby driving the rope, the rope tension can be adjusted by using the tension wheel. The lifter fewer parts used, their light quality, ease of processing, a small footprint, commonly used in small cars.
6. The belt lifter
it moves flexible shaft with a perforated plastic, plastic products resembles other parts, thus greatly reducing the mass of regulator assembly itself. Its transmission mechanism are coated with grease, use the process without maintenance, smooth movement. Crank position of the handle can be arranged freely, design, installation and adjustment.
7. A cross-arm window regulator
is a seat board, a balance spring, the sector gear plate, strip, glass bracket mainBoom, boom, the guide plate groove, gaskets, springs, crank pinion shaft composition.
8. The flexible glass lifter
Formula flexible transmission mechanism of automobile glass lifter flexible shaft engaged transmission gear, having ldquo; soft formula rdquo; characteristics, so provided, mounted are more flexible and convenient, structural design is relatively simple and compact structure itself, the overall quality of light.
