Assembly systems for Door systems

Window lifters are assemblies for lifting and lowering the side windows. They are driven manually or electrically. A typical design of electrical window lifts consists of guide rails, window brackets, electric motor, bowden cables, cable drum and deflection pulleys. Both ends of the Bowden cable are connected in opposite directions to the cable drum and are rolled up or unwound according to the direction. Since the bowden cables are fixedly connected to the window supports, which in turn run up and down the guide rails, the disc moves. For safety reasons, an anti-pinch protection is integrated. Operation is carried out by means of buttons in the inner panel. In addition to the outer skin and the interior trim, door modules are components of modular vehicle doors. They are used to integrate mechanical, electrical and electronic function modules. An exemplary structure consists of carrier plate, window lifter, lock module, exit light, loudspeaker as well as wiring harness, control devices and seals. The design and equipment can vary greatly depending on the manufacturer and the model. Modern door modules are often available in several hundred variants and are produced just-in-sequence. They are made of glass-fiber-reinforced polypropylene in light-weight solutions. According to Brose, in the case of light-weight solutions alone, the door modules save 350 grams by weight compared to conventional plastic door systems. Door systems are used by OEMs for passenger cars as well as utility vehicles and special vehicles.
