🖥 all wheels must be attached to the car with wheel tethers. these are strong cables that keep wheels connected to the car in the event of an accident. ( 9/9 )

⬜️ most of the element's of the suspension of a F1 car are made from Carbon Fiber for better aero forms.

➕ Wheel tethers are often made from Kevlar fibers or similar high-strength materials due to their excellent tensile strength and lightweight properties. Kevlar is known for its durability and resistance to impact, making it an ideal choice for applications where safety and performance are critical, such as in motorsports.

🖥 Pull-rod Vs Push-rod : Explained ! ( 1/10 )

⚠️This picture shows the design of push-rod and pull-rod suspension systems.

◻️ If you don’t have enough time to read this entire content:

🔵 push-rod suspensions offer better packaging and are easier to tune, making them ideal for handling balance, but they can slightly compromise aero efficiency due to higher placement of components. Pull-rod suspensions, on the other hand, improve aerodynamic efficiency by keeping components lower, helping reduce drag and lowering the center of gravity, but they are more challenging to set up and maintain. Both systems affect handling differently based on how they're tuned, with pull-rod often being more beneficial for rear suspensions in high-performance cars like F1 cars.

🖥1. Push-Rod Suspension ( 2/10 )
In a push-rod suspension, the rod that connects the wheel hub to the suspension pivots upwards from the wheel to the chassis.
When the car hits a bump, the suspension compresses, and the push-rod gets pushed up, transmitting the force upwards.
The force is then transferred to a rocker mounted on the chassis, which compresses the damper (shock absorber) and spring located within the chassis or along the sides.

✔️

Advantages:
Better packaging options,
Typically seen in Formula 1 cars and other high-performance vehicles.
Better cooling as suspension components like dampers are positioned outside the flow of hot air from the car's engine.

🖥 2. Pull-Rod Suspension ( 3/10 )
In a pull-rod suspension, the rod is positioned lower, and it angles downwards from the wheel hub to the chassis.
When the suspension compresses over a bump, the pull-rod is pulled down, transferring the force in the opposite direction to the damper and spring.
Like the push-rod system, the force is transmitted to a rocker, which then compresses the damper and spring, but the difference is that the force is pulling rather than pushing.
✔️Advantages:
Provides a lower center of gravity due to the lower placement of the suspension components.
Helps improve the car's aerodynamics by lowering the car and its associated parts.
Frequently used in high-performance rear suspensions of Formula 1 cars. ( I think Haas and Ferrari are using pull-rod in their rear suspension system )

🖥 Key Differences: ( 4/10 )

✔️

Direction of force: In push-rod suspensions, force is pushed upward; in pull-rod suspensions, force is pulled downward.

✔️

Component Placement: Pull-rod suspensions tend to have lower placement of components, improving aerodynamics and lowering the center of gravity more effectively.

✔️

Application: Push-rod suspensions are generally easier to set up and maintain, while pull-rod suspensions are more aerodynamically efficient but can be harder to work with due to tighter packaging.
Both systems aim to improve the performance and handling of high-speed vehicles but have slight differences in their design and function based on how the forces are distributed through the suspension system.

🖥 When it comes to understeering and oversteering, both push-rod and pull-rod suspension systems can impact the car’s handling differently, although the design of these systems is just one part of the equation. The behavior of a car in understeering or oversteering is influenced by the suspension setup, weight distribution, and how the suspension components respond to forces. Let’s break it down: ( 5/10 )

🖥 1. Push-Rod Suspension and Handling: ( 6/10 )
✔️ Stiffness and Geometry: In a push-rod system, the way the suspension is set up (stiffness, damping) can affect the car’s response during cornering. If the suspension is too stiff, it may lead to understeering, especially if the front suspension is stiffer than the rear.
✔️ Lower Center of Gravity: Since pull-rod systems can help lower the car's center of gravity, they generally provide better balance in corners, which can reduce understeering. The car becomes more responsive, but how much oversteer or understeer occurs depends on how the front and rear suspensions are tuned.

🖥 2. Pull-Rod Suspension and Handling: ( 7/10 )
✔️ More Aerodynamic Efficiency: Pull-rod suspensions are often used in rear suspensions of race cars like Formula 1 due to their better aerodynamic efficiency and lower component placement. This lower center of gravity can enhance the car’s ability to handle well through corners and reduce oversteering, especially at high speeds.
✔️ Fine-Tuning Oversteer and Understeer: In a pull-rod system, the rear suspension can be tuned to either increase or reduce oversteer. Typically, if the rear suspension is stiffer or set up with less damping, the car might experience oversteer, where the rear of the car wants to slide out in corners. On the other hand, a softer rear suspension could lead to understeer, where the front tires lose grip before the rear tires.

⚙️ Understeering vs. Oversteering Behavior: ( 8/10 )
✔️ Understeering: This happens when the front tires lose grip in a corner, causing the car to turn less than the driver intends. A push-rod suspension setup in the front that’s too stiff or incorrectly balanced can contribute to understeering, as it can reduce the front tire's ability to maintain grip.

✔️ Oversteering: This occurs when the rear tires lose grip first, making the rear of the car slide out. A pull-rod suspension at the rear, if too stiff, can cause oversteering. But a well-tuned pull-rod suspension can help prevent oversteer by keeping the rear of the car stable through corners.

⚙️ Balancing the Car: ( 9/10 )

🔴

In race cars (like those with pull-rod or push-rod systems), the goal is usually to balance the suspension to minimize understeer and oversteer. Engineers use the adjustability of these systems (such as changing spring stiffness, damper rates, and ride height) to fine-tune how the car handles in different conditions.

🔄

For example, they might set the front suspension softer to reduce understeer and keep the rear firmer to manage oversteer.

🖥 Summary: ( 10/10 )
⬜️Push-Rod: If the front is too stiff, it can cause understeering. A properly tuned push-rod suspension can help balance the car better.
🟦Pull-Rod: Typically found in the rear suspension, a stiff setup can cause oversteering, while a softer setup can lead to understeering. The goal is to balance these to make the car as neutral and responsive as possible.
Ultimately, the suspension type (push-rod or pull-rod) plays a role in the car’s overall balance, but tuning (springs, dampers, and geometry) is what determines the car's tendency to understeer or oversteer.

⚠️ Overall, the pull-rod suspension system is much more complex than the push-rod system. Currently, I think Red Bull is the only team on the grid using front pull-rod suspension. Due to the cost cap, challenging updates involved, not many teams dare to switch to this type of suspension. As we can see, Red Bull has faced issues after Adrian Newey's separation from the team, and one of the reasons could be the complexity of this setup.

🖥 Rocker : Explained !

⚠️ In the suspension system of a Formula 1 (F1) car, a rocker (also known as a rocker arm) is a crucial component that plays a significant role in the car's handling and suspension dynamics. Here’s a brief overview of what a rocker is and its function:

✔️What is a Rocker?
The rocker is a lever-like component that connects the suspension elements, such as the push-rod or pull-rod, to the spring and damper (shock absorber).
It is typically mounted on a pivot point, allowing it to rotate.

🔔Functions of the Rocker:

➡️Force Distribution: The rocker transmits forces from the wheel through the push-rod or pull-rod to the springs and dampers. It converts vertical movement from the wheel into a horizontal motion that compresses the spring.

➡️Suspension Geometry: The rocker helps maintain the desired suspension geometry during the wheel's movement. By altering the angle of the rocker during suspension travel, it can affect how the suspension behaves under different loads and conditions.

➡️Adjustable Characteristics: The design and placement of the rocker can be adjusted to change the car’s handling characteristics. By modifying the rocker’s pivot point and length, engineers can influence how the car responds to bumps and turns, optimizing the balance between understeer and oversteer.

➡️Weight Distribution: The rocker helps distribute the load more effectively across the suspension components, contributing to better weight transfer during acceleration, braking, and cornering.

🔗Summary
In summary, the rocker in an F1 car's suspension system is a vital component that aids in force transmission, influences suspension geometry, and can be adjusted to optimize the car's handling characteristics. It plays a key role in ensuring the car maintains optimal contact with the track, improving performance and stability.

🖥 Heave damper/spring : Explained ! ( 1/6 )

✔️ What is Heave Damper?
A heave damper is a part of the suspension system that helps manage the vertical movement (up and down motion) of the car. This vertical movement is called heave and happens when the car hits bumps, or when aerodynamic forces (like downforce) push the car down.
