The Importance of Steering and Suspension

Steering

Precise steering allows drivers to navigate through obstacles, corners, and different terrain effectively. Electric RC cars typically use three common steering systems:

• Servo Steering: A popular option for its accuracy and adjustability, servo steering involves a servo motor attached to the front wheels.
• Ackermann Steering: This geometry ensures that the inside and outside wheels turn at different angles during a corner, preventing tire slippage and improving stability.
• Rack-and-Pinion Steering: A rack-and-pinion system utilizes a toothed rack attached to the steering wheel and a pinion gear connected to the wheels, providing smooth steering control.

Suspension

A well-tuned suspension system absorbs impacts, stabilizes the car during acceleration and braking, and maintains optimal tire contact with the ground for improved grip and handling. For electric RC cars, the following suspension types are commonly used:

• Independent Suspension: Allows each wheel to move independently, ensuring constant tire contact and improved stability.
• Beam Axle Suspension: A solid axle connects both rear wheels, providing simplicity and durability, but limiting individual wheel articulation.
• Double-Wishbone Suspension: Utilizes two wishbones (arms) connected to the wheel hubs and frame, allowing independent movement and fine-tuning of suspension geometry.

Factors to Consider When Optimizing Suspension

1. Spring Rate: The stiffness of the springs determines how quickly the suspension compresses and rebounds. A stiffer spring absorbs less impact but provides better cornering.
2. Damping: Shock absorbers or oil-filled dampers dissipate excess energy from the suspension, preventing it from bouncing excessively and improving car stability.
3. Ride Height: Adjusting the ride height affects the vehicle’s center of gravity and handling characteristics. A lower ride height improves stability, while a higher ride height provides more ground clearance.
4. Camber Angle: The angle at which the wheels lean in or out can be adjusted to optimize cornering performance. Negative camber increases tire contact during turns, but can affect straight-line stability.
5. Toe Angle: The alignment of the wheels, either pointed in or out, has a significant impact on the car’s handling. Toe-in increases stability during braking and turning, while toe-out improves cornering but compromises straight-line tracking.
