How about the direction of the wheel to the right?
In theory, the front wheel of the tilt and tilt are designed by the design and manufacture, no external collision without adjustment, but the actual maintenance found that there are some A3 new car without external deformation, there is a large difference between the left and right sides , Need to be adjusted. And most of the maintenance staff that, since the front-wheel dumping and dumping by the design and manufacture of assurance, without adjustment, so often do not measure it, but only before and after the tilt and the front beam value, making the standard data in place, Still partial line. In view of the above, it is recommended that maintenance personnel in the positioning, pay full attention to all the positioning parameters, and the relevant angle to make the necessary adjustments.
The analysis shows that the left front wheel is much more inclined than the right side, and the equivalent judgment is that the center of gravity of the vehicle is tilted to the right, and the outward inclination of the right front wheel is adjusted as far as possible to the negative camber direction, The center of gravity of the vehicle is adjusted to the left. Adjust the front wheel backwards to: left: + 0.12 °, right -0.54 °, front beam left + 0.01 °, right + 0.02 ° after re-measuring front wheel tilting and tilting: rearward left: + 2.4 °, right + 2.5 °, introverted left: 13.4 °, right + 11.7 °. Re-test, the right side of the line to disappear.
Enter the locator shortcut to check the four wheel positioning data, the rear camber left: -0.3 °, right: -0.45 °; rear front beam left: + 0.03 °, right: -0.28 °. Front wheel outward left: -0.43 °, right: -0.28 °; front wheel front beam left: + 0.03 °, right: -0.24 °. From the data to see this car forward angle to the right offset, theoretically the car should be biased to the left, the positioning parameters of the adjustment, the rear front beam for the left + 0.03 °, right: +0.04 °, : Left: +0.01 ° right + 0.02 ° after the test and found that the partial line for more right deviation, re-positioning device, check all parameters: front wheel rear left: + 2.5 °, right: + 2.37 °; : Left + 20.2 °, right: + 3.6 °, it seems that the cause of deviation in the front wheel on both sides of the difference is too large, due to the front wheel tilt and dumping by the design and manufacture to ensure the correctness of its angle, the car is not the product car There may be collision deformation, try to front sub-frame four fixed nuts loose to the right to adjust and found that the gap is small can not be effectively adjusted.
