Automotive Applications of Linear Actuators in the Car-Making Industry

Currently, there is rapid growth and development in the automotive industry. Every day, manufacturers are striving to come up with new innovative ways to keep the costs of development low and automate the cars` performance to the best of their capabilities.

One of the modalities to do so has been investing in performant actuators. For instance, a linear electric actuator act out many functions in RVs, cars, and heavy equipment.

Linear Actuators for the Vehicle`s Interior-Making

The following is a list of the most popular applications of actuators. The first part of the user is focused on the interior part of the car, whereas the other part looks at the car as a whole.

1. Steering Wheel

As a driver, you might know that the steering wheel position regulates a widespread of movement, which can improve the comfortability when driving. By using a linear actuator, it is possible to draw the steering wheel either close or far when searching for the most comfortable suitable position.

2. Seats

 Rotational actuators can be found for the lumbar regulation of seats and the automatic regulation of their position and height.

3. Headrest

 Rotational actuators can be used for automatic adjustment of the headrest.

Automotive Actuators Present in the Bodywork

1. Side Mirror Positioning

 Linear actuators and lead screws are used in providing rotation and automatic tilt of side mirrors.

2. Headlights

They also have a usage in headlight washing systems. There, linear actuators allow displacements of the cleaning mechanism of lights.

In the case of height regulation systems, they fulfill the following role: a gear motor that gives an angular movement. These adaptive headlights can be used to regulate the height of the lights or the orientation of the blades used in air conditioning.

3. Engine Block

Automotive actuators are used for activating the control valves of fluids and gases. This drive mechanism is usually found on the windshield, and it tends to have an internal relay inside the engine. This mechanism opens or closes the contacts which provide voltage to the wiper’s motor.

In addition, some wiper’s motor usually has intermittent relays which relay on a timer which helps to manage the movements.

4. The Lid of the Gasoline Tank

It has a role in ensuring a safe drive. An electric actuator is used to close and open the lid where the gasoline is deposited. That way, it makes sure that there will be no leakages.

5. Trunk

 Currently, the number of brands that use automated drives for closing and opening the tailgate is rapidly growing. They use a mechanical transmission from hydraulic actuators to operate this movement. These products are durable. It is because there is no wear as a result of friction between its components.

Some manufacturers use pneumatic conveying for tailgate opening systems. In this case, the energy from the air pressure is usually in charge of starting the movement.

6. Door Openers

Lead screws and electric linear actuators are used to close and open sliding doors that have retouch openers.

How do Automative Actuators Work?

Automotive actuators print a force in order to move a mechanical device. They can exert strength with a pneumatic, electrical, hydraulic, or magnetic dimension. The solutions and inventions that are offered in the driving sector are aimed toward improving the safety and comfort of the members in a vehicle. Linear actuators are used whenever an automotive part needs to be lifted, lowered, opened, or closed.

Automotive actuators are the least known pieces, but they have really had an influence on the emergence of new movements. With the industry becoming so much competitive, any small detail can influence the final consumer making the purchase.

5 Types of Actuators and How they Work

  • Hydraulic: These are actuators that generate movement from the displacement of fluids.
  • Pneumatic: They generate resistance or force through air pressure. They can be found in systems of tailgate lifting.
  • Electric: They are actuators that drive where motors intervene.
  • Electromagnetic: They are those that are based on electromagnetism, either through an electromagnet or magnet. They are normally used in mechanisms of the vehicle that operate with an electric current.

The Bottom Line

Linear actuators are becoming very popular with people who want to restore a piece of functionality that has been lost to their vehicle or to add a custom motion element. They have proven to be durable and more energy-efficient, making them highly desirable in automation and in the automotive industry.

By installing a linear actuator, you save on costs to your motion problem, thereby avoiding the issue of complicated drive systems, using weakly rotary servos, or expensive microactuators.
