Analysis of the application of rotary hinges in vehicle tailgates

Introduction

The tailgate of a vehicle is an important component that provides access to the cargo area. The traditional tailgate design involves hinges that allow the tailgate to swing open horizontally. However, in recent years, there has been an increasing trend towards the use of rotary hinges in vehicle tailgates. This analysis aims to explore the advantages and disadvantages of rotary hinges and their application in vehicle tailgates.

Advantages of Rotary Hinges

Rotary hinges offer several advantages over traditional hinges for vehicle tailgates:

1. Space-saving: Rotary hinges take up less space than traditional hinges, making them ideal for vehicles with limited cargo space.
2. Improved aerodynamics: Rotary hinges can improve the aerodynamics of a vehicle by reducing drag and wind noise.
3. Better stability: Rotary hinges provide better stability to the tailgate, reducing the risk of it slamming shut unexpectedly.

Disadvantages of Rotary Hinges

While there are several advantages to using rotary hinges in vehicle tailgates, there are also some disadvantages:

1. Cost: Rotary hinges are more expensive than traditional hinges, which can increase the cost of the vehicle.
2. Complexity: Rotary hinges are more complex than traditional hinges, which can make them more difficult to install and maintain.
3. Weight: Rotary hinges are typically heavier than traditional hinges, which can increase the weight of the tailgate and reduce fuel efficiency.

Application of Rotary Hinges in Vehicle Tailgates

Despite the disadvantages of rotary hinges, they are becoming increasingly popular in vehicle tailgates. Some examples of vehicles that use rotary hinges in their tailgates include:

1. Ford F-150: The Ford F-150 uses a rotary hinge system called the “EZ-Lift Tailgate” that allows the tailgate to be opened and closed with one hand.
2. Chevrolet Silverado: The Chevrolet Silverado uses a rotary hinge system called the “EZ Lift and Lower Tailgate” that allows the tailgate to be opened and closed with one hand and also provides a dampened lowering action.
3. Dodge Ram: The Dodge Ram uses a rotary hinge system that allows the tailgate to be opened and closed with one hand and also provides a dampened lowering action.

Overall, the application of rotary hinges in vehicle tailgates offers several advantages over traditional hinges, including space-saving, improved aerodynamics, and better stability. While there are some disadvantages to using rotary hinges, their benefits are leading to an increasing trend towards their use in vehicle tailgates.
