Door handles and their working

 In Uncategorized

How many times each day do you use the door handles on your car, truck, or SUV? You may have never even thought about it, but your door handles are used quite frequently. Like other moving parts, the more they are used, the more wear and tear they are going to incur. Of course, we don’t think you should stop using your door handles altogether; that would be just plain silly. However, paying some attention to the condition of your door handles may keep you from an unpleasant period when one or more of them stop working. Keep in mind that you have more than one door handle for each door of your vehicle. Your side doors have both an inner and an outer door handle, and if you have a tailgate or hatchback, there is another handle installed on the rear of your vehicle. Typically, door handles are either metal or plastic, and work in conjunction with toothed wheels called rotors installed in the side panels of your doors. These rotors are also responsible for keeping your vehicle safe, as they do not move when your door locks are engaged. When just one of your doors handles breaks, it can be a real inconvenience. For instance, if your interior driver’s side door handle is not working, you are going to have to either roll down your window or try to open the door from the outside or slide across to the passenger’s side to get out of your vehicle. If your door handles start to rust, loosen, or stiffen through use, don’t wait to order new door handles or a door handle repair kit from our expertise.

In this car, the power-door-lock actuator is positioned below the latch. A rod connects the actuator to the latch, and another rod connects the latch to the knob that sticks up out of the top of the door.

When the actuator moves the latch up, it connects the outside door handle to the opening mechanism. When the latch is down, the outside door handle is disconnected from the mechanism so that it cannot be opened. To unlock the door, the body controller supplies power to the door-lock actuator for a timed interval.
