What is an Camber Eccentric Screw?
The main reason why cars use Camber Eccentric Screw is to adjust the positioning parameters of the wheels.
An Camber Eccentric Screw is a special screw whose central axis does not coincide with the central axis of the screw hole. When the eccentric screw is rotated, due to its eccentric characteristics, it can cause a certain displacement of the parts connected to it.
There are several important reasons why cars use Camber Eccentric Screw:
1.Adjusting the wheel angle
Camber adjustment
Reason: The wheels of a car need to maintain a proper camber angle during design and actual driving. Camber refers to the angle of inclination of the wheel relative to the vertical direction when viewed from the front of the car. Under normal circumstances, the wheel will have a slight camber, which helps the vehicle better cope with changes in the road surface during driving.
Answer: The camber angle of the wheel may change when the vehicle's suspension system is slightly deformed, the vehicle has been repaired after a collision, or to adapt to specific driving needs (such as racing cars require more precise wheel angle settings). Camber Eccentric Screws can be used to fine-tune the camber angle of the wheel. For example, by rotating the Camber Eccentric Screw, the top of the wheel can be moved inward or outward, thereby changing the size of the camber angle. The appropriate camber angle ensures good contact between the tire and the road, even wear, and provides better lateral support when the vehicle turns.
Cast angle adjustment
Reason: Caster angle is the angle between the kingpin axis (steering knuckle rotation axis) and the vertical direction when viewed from the side of the vehicle. It plays a vital role in the steering stability and self-centering of the vehicle.
Answer: If the caster angle is not set properly, the vehicle may turn heavily during driving or the wheels may not be able to return to the center automatically after turning. Camber Eccentric Screws can be used to adjust the caster angle and change the inclination of the kingpin axis. For example, increasing the caster angle can improve the stability of the vehicle's straight-line driving, making the vehicle more inclined to maintain a straight-line driving state during driving; while appropriately reducing the caster angle can make steering easier, which is more advantageous in some special driving scenarios (such as frequent steering in a small space).
2.Specific application scenarios
① After the accident repair:
When a car is involved in a collision, the suspension system is likely to be damaged, resulting in changes in the wheel alignment parameters. Using Camber Eccentric Screw can quickly and accurately adjust the wheel alignment parameters to restore the car to a good driving state.
② When modifying the vehicle:
Some car owners will modify their vehicles to improve the handling performance of the vehicle, such as replacing lower or higher suspension springs. This modification may change the wheel alignment parameters. Camber Eccentric Screw can help adjust the parameters to adapt to the new suspension system to ensure that the vehicle can still drive safely and stably after modification.
③ In daily repairs and maintenance:
Even if there is no accident or modification, the parts of the suspension system will wear out during the long-term use of the car. For example, ball head wear, rubber bushing aging, etc. may cause slight changes in wheel alignment parameters. Camber Eccentric Screws can be used to fine-tune these parameters, extend the service life of the tire, and improve the driving comfort and safety of the vehicle.
