Front door lifter assembly-LOW configuration-L/R
glass regulator
The glass lifter is the lifting device for the glass of the automobile door and window, mainly divided into two categories: electric glass lifter and manual glass lifter. Nowadays, the lifting of the door and window glass of many cars is generally switched to a button-type electric lifting method, using an electric glass lifter.
Most of the electric window regulators used in cars are composed of motors, reducers, guide ropes, guide plates, glass mounting brackets, etc. The master switch controls the opening and closing of all door and window glass by the driver, and the sub-switches on the inner handles of each car door control the opening and closing of each door and window glass respectively by the occupant, which is very convenient to operate.
Classification
arm and soft
Automotive window lifters are structurally divided into arm-type glass lifters and flexible glass lifters. The arm type glass regulator includes a single arm type glass regulator and a double arm type glass regulator. Flexible glass regulators include rope wheel glass regulators, belt glass regulators and flexible shaft glass regulators.
Arm Window Regulator
It adopts a cantilever support structure and a gear-tooth plate mechanism, so the working resistance is relatively large. Its transmission mechanism is a gear tooth plate and meshing transmission. Except for the gear, its main components are plate structure, which is easy to process and low in cost. It is widely used in domestic vehicles.
Single Arm Window Regulator
Its structural feature is that there is only one lifting arm, and the structure is the simplest, but because the relative position between the supporting point of the lifting arm and the center of mass of the glass changes frequently, the glass will be tilted and stuck when it is raised and lowered. This structure is only suitable for parallel glass on both sides. Straight edge case.
Double Arm Window Regulator
Its structural feature is that it has two lifting arms, which can be divided into parallel arm type lifter and cross arm type lifter according to the arrangement of the two arms. Compared with the single arm type glass lifter, the double arm type glass lifter itself can guarantee The glass is lifted and lowered in parallel, and the lifting force is relatively large. Among them, the cross-arm glass regulator has a large support width, so the movement is relatively stable, and it is widely used. The structure of the parallel arm glass regulator is relatively simple and compact, but due to the small support width and large changes in the working load, the movement stability is not as good as the former.
Rope wheel glass regulator
Its composition is the meshing of pinion, sector gear, wire rope, moving bracket, pulley, pulley, and seat plate gear.
The pulley fixedly connected to the sector gear is driven to drive the steel wire rope, and the tightness of the steel wire rope can be adjusted by the tension pulley. The lifter uses few parts, is light in weight, easy to process, and takes up little space. It is often used in small cars.
Belt type glass regulator
Its sports flexible shaft adopts plastic perforated belt, and other parts are mostly made of plastic products, thus greatly reducing the weight of the lifter assembly itself. The transmission mechanism is coated with grease, no maintenance is required during use, and the movement is stable. The position of the crank handle can be freely arranged, designed, installed and adjusted.
Cross Arm Window Regulator
It is composed of seat plate, balance spring, fan-shaped tooth plate, rubber strip, glass bracket, driving arm, driven arm, guide groove plate, gasket, moving spring, crank handle, and pinion shaft.
Flexible glass regulator
The transmission mechanism of the flexible automotive window regulator is geared and flexible shaft meshing transmission, which has the characteristics of "flexible", so its setting and installation are more flexible and convenient, and the structural design is relatively simple, and its own structure is compact and the overall weight is light
Flexible shaft lifter
It is mainly composed of a window motor, a flexible shaft, a formed bushing, a sliding support, a bracket mechanism and a sheath. When the motor rotates, the sprocket on the output end meshes with the outer contour of the flexible shaft, driving the flexible shaft to move in the forming sleeve, so that the sliding support connected with the door and window glass moves up and down along the guide rail in the bracket mechanism, achieving The purpose of lifting glass.
