How Does a Hood Latch Work?

Hood Latch Mechanism

The hood latch mechanism in a car is a elementary device. Although almost cars are manufactured with similar hood release systems, they are individually designed for each make and model. This ways that even though they all perform very similarly, they cannot be uninstalled from 1 make and model and and then reinstalled in a different brand and model. The overall concept of the mechanism is the same, merely the schematics and design of the hood latch system is unlike on each vehicle. The hood latch system begins inside the compartment of the car. Located on the driver's side (ordinarily on the left-hand lower corner of the dashboard) is the hood release handle. The hood release handle attaches to a cablevision which so routes through the dashboard towards the front of the vehicle. The other terminate of the cable is attached to a secondary latch, which is manipulated by the pulling of the cablevision (activated by pulling the hood release lever). But an inch or two is required to pull the secondary latch away from its position, and then the hood pops open up. At the forepart of the vehicle, a safe latch retains the hood. Locating and releasing the prophylactic latch releases its concur on the hood and then the hood is immune to open.

Components of a Hood Latch System

The hood release handle inside the vehicle is made of plastic and is attached straight to the hood latch cable. The cable has a protective outer lining to prevent corrosion of the cable where information technology is exposed to the elements. The cablevision is designed to move inside the lining back and forth to accommodate the pulling and releasing movement of the handle and the secondary latch. The opposite end of the cable is attached to the secondary latch, usually near the bottom. When tension is applied to the cable from the hood release handle, it pivots the secondary latch, which pulls away from a retaining seat located under the hood. By pattern, the secondary latch and so releases the hood a few inches earlier a safety latch takes over. The prophylactic latch is integrated in the hood latch organisation in case of accidental release of the handle inside the passenger compartment during functioning of the vehicle. Without the safety latch, the hood would be susceptible to flying up then back towards the windshield, blocking the driver'southward vision, and most probable causing extensive damage to the hood, the hood hinges, and the windshield. The safety latch has a release lever which pivots slightly by moving it, which then releases the safety latch from its seated position of the hood. Virtually safe latches crave release with no tension on the hood. This means, yous most likely take to press the hood downwards slightly back in the closed position, thus taking the slight pressure off the safety latch to maneuver it and release it from the seat. Once that is washed, the hood is costless to open. Many hoods apply a prop rod integrated with the vehicle. The prop rod is located on the upper frame of the front or side rails and fastened at the bottom. A small prune holds the upper end of the rod in place. Release the rod from the clip, swing information technology upward and locate its seating position (normally marked) on the underside of the hood. Other models may have the prop rod attached to the underside of the hood and the seating position located on the upper frame rails. High-end vehicles are now using hydraulic hood shocks to automatically open up car hoods and replace the hood prop rod altogether.

Maintenance to the Hood Latch Components

After many uses and normal wear and tear, the hood latch mechanism has common areas of deterioration. The pull handle, often made of plastic can simply intermission. The cable can seize up within the lining (usually on the cease attached to the secondary latch where information technology's exposed to the elements). The secondary and condom latches can dry out up existence exposed to the elements and non release properly or may non return to the closing position require to close the hood properly. Although a hood release latch may allow you lot to open a car hood, if it is not performance properly, it may forbid you lot from closing it. White lithium grease and regular maintenance are the two best friends a hood latch organisation has. A small amount of grease on each end of the cable (the interior side of the cable is protected against the elements of weather and deterioration so usually require little maintenance) to lubricate it and prevent information technology from seizing upward inside the lining usually keeps the cable working well. If y'all wait until the cable is sticking or is seized altogether, you most likely will be too late for the maintenance of the cable and replacement may be required. White grease on the secondary and condom latches is too strongly recommended to keep the latches swinging on the riveted hinges. Both the secondary and safety latches too integrate a tension spring. Keeping the springs lubricated helps them restore their tension. Keeping these components lubricated during every oil change will help provide longevity and reliability to the hood latch system.
