Everybody heard four wheel alignment,
but the new owners may be unfamiliar. The vehicle long after it may
feel in automobile running straight will bias left Huobian right, body
will be floating pole, tires have unilateral wear phenomenon occurs,
then you need to do some four wheel alignment. Knowledge of vehicle four
wheel alignment knowledge when you are doing maintenance time, you can
more accurately monitor, but also in the clear what situations need to
do four wheel alignment, so give your safety also brings many security.
Then let us know some four wheel alignment knowledge, prevent the repair
factory fish in troubled waters.
Because the vehicle four wheel, steering, rear axle between the mounting
should have certain relative position, the relative position is
determined by the manufacturers standard value. Adjustment of the
position of the installation is restored, 4 wheel aligner.
Popular understanding is that the front wheels of the vehicle alignment and the rear wheel alignment
collectively called four wheel alignment, front wheel alignment
includes caster ( angle ), kingpin inclination ( angle ), camber and
toe-in ( angle ) of four content; rear wheel alignment includes camber (
angle ) and one rear wheel before the beam.
What circumstances do you use four wheel alignment?
1 The running performance of the vehicle under the influence (vehicles
on the road running straight when the wheel is in flat, moving straight
left or right sliding, the body will beat the instability, the steering
wheel can swing, running in case.
2 Tire wear is not normal, serious eats fetal phenomenon ( but also to
take into account whether by fetal abnormal pressure can cause abnormal
wear, under normal circumstances, the tire pressure is too high will
aggravate the central tread wear, and the tire pressure is too low will
aggravate the tread sides wear; if one of the eccentric wear, there may
be a camber angle deviation.
3 Because of accident of chassis and suspension damage;
4 Replacement suspension, steering system, a tripod or connecting rod chassis parts;
Four wheel alignment type
Four wheel alignment before the beam size and optical level wheel alignment, cable locator, CCD wheel alignment,
laser wheel alignment instrument, and 3D image wheel alignment of
several. The 3D, CCD and laser products are currently the three main
products on the market,3D products are currently on the market the most
advanced four wheel alignment, measurement method, measurement time is
only advanced traditional wheel alignment instrument1/5, has gradually
entered the mature stage.
Some owners have to ask, why four wheel alignment, laser four wheel
alignment which benefit woollen cloth. In fact, it is not difficult to
imagine, driving for a long time, some parts will wear, with needless to
say occurred accidents or disassembled, in fact the summing point is to
ensure that your driving safety, four wheel alignment is automotive
repair and maintenance required one of working content.
Do four wheel alignment can not only enhance the driving comfort, but
also can reduce the consumption of gasoline, while increasing the
service life of tire, reducing chassis suspension parts, so as to ensure
that the vehicle straight line stability.
Four wheel alignment adjustment data
1 caster
Role: linear stability, turning.
2 kingpin inclination
Role: stability, turning.
3 wheel camber ( negative camber )
Effect: increase the tyre contact surface, offset the adverse effects.
4 toe ( before the show)
Role: offset wheel camber ( introverted) adverse effects.
How to identify the four wheel alignment adjustment results?
First of all, you can run, it is the most intuitive feelings. With you
before the discomfort of a comparison, can be very intuitive to confirm
the adjustment results.
Secondly, you can see the four wheel alignment testing report. Four wheel alignment is different, but the adjustment of the data is the same principle, therefore also
consistent.
