The principle of Guangdong Roadback four-wheel aligner

The principle of Guangdong automobile four-wheel aligner mainly involves the precise measurement and adjustment of the four-wheel parameters of the vehicle to ensure the stability and controllability of the vehicle while driving. The following is a detailed explanation of the principle of a car four-wheel aligner:

1. The function of four-wheel aligner

Guangdong Roadback vehicle wheel aligner is a precision measuring instrument used to detect vehicle wheel alignment parameters. It measures the relative angle between the wheels and the centerline of the vehicle, as well as the relative position of the wheels and the rear axle, to ensure that the four wheels of the vehicle work together in the most ideal posture. During this process, the four-wheel aligner will compare with the original design parameters and guide the user to adjust the wheel alignment parameters accordingly to make them meet the original design requirements, thereby achieving ideal vehicle driving performance.

2. Working principle of four-wheel aligner

Data collection:

The data collection part of the four-wheel aligner usually consists of four measuring probes. The sensors (such as CCD) in these probes can sense the light coordinates of the infrared emission tubes on the corresponding measuring probes.

These light coordinate information are transmitted to the wireless receiver in the cabinet through the wireless transmitter, and then transmitted to the computer host through the COM port in the industrial computer for calculation and processing.

Data processing and display:

The data processing part of the four-wheel aligner mainly includes a computer system, power supply system and interface system.

The computer system is used to realize the user's command operation of the four-wheel aligner, and to collect and process the image data of the sensor.

The processed data will be displayed together with the original design parameters, and the user will be guided to adjust the car wheels.

Adjustments and feedback:

Based on the measurement results of the four-wheel aligner, the technician can adjust the wheel alignment parameters (such as toe, camber, etc.) to make them comply with the original factory design requirements.

After the adjustment is completed, the four-wheel aligner can be measured again to ensure that the adjustment effect is as expected.

3. Parameters of four-wheel alignment

The parameters of four-wheel alignment mainly include front wheel alignment and rear wheel alignment:

Front wheel alignment: involves the installation relationship between the steering wheel, steering knuckle and front axle. The main parameters include kingpin caster, kingpin inclination, front wheel camber and front wheel toe. These four factors jointly affect the vehicle's steering, driving stability and tire wear.

Rear wheel positioning: Adjust the relative position of the rear axle wheels and the rear axle, including wheel camber and rear wheel toe-in one by one. This is key to maintaining vehicle balance and reducing tire wear.

4. Precautions for using the four-wheel aligner

Before performing a four-wheel alignment, it is necessary to check the vehicle suspension, wheel bearings, steering system, etc. for gaps and damage. The tread depth tolerance of vehicle tires should be within the specified range, and the tire inflation pressure also needs to comply with the regulations.

When performing four-wheel alignment, you should strictly follow the steps displayed on the locator and do not allow any steps to be omitted.

When adjusting each wheel alignment parameter, it should comply with the requirements of the "Maintenance Manual" of each vehicle model. For situations that do not meet the specified requirements, corresponding adjustments need to be made, except where the original vehicle cannot be adjusted.

To sum up, the principle of Guangdong Roadback's four-wheel aligner is to accurately measure and adjust the positioning parameters of the vehicle's four wheels to ensure the stability and controllability of the vehicle while driving. When using a four-wheel aligner, you need to pay attention to relevant operating specifications and precautions to ensure the accuracy of measurement results and the effectiveness of the adjustment effect.
