wheel alignment equipment

Designed entirely around heavy commercial vehicle applications, the laser measuring equipment Steertrak uses has been accepted on an industry wide basis, and is used by many European truck manufacturers for quality control. The equipment has two crucially important features setting it apart from other systems.

ELIMINATES WHEEL RIM RUN OUT. The wheel alignment must be referenced to the centre line of the axle stub, NOT the outside of the wheel rim. Errors in the wheel rim and tyre mounting must be compensated for. Many alignment systems originally designed for cars and often used on commercial vehicles do not have this capability.

REFERENCES CENTRELINE OF CHASSIS. Self-centring gauges are mounted from the chassis to enable readings to be taken from the centre line of the vehicle and not, as is the case with many other systems, from the rear axle which is often found to be misaligned to start with. 

EQUIPMENT CALIBRATION. Routine maintenance and calibration of the laser wheel alignment equipment is also critical for accurate and reliable measurement. All Steertrak engineers are trained in these procedures.

Steering axis inclination 13°00’ ± 45’
Camber, caster and steering axis inclination are not adjustable.
If measurements are not within the specification, inspect the
suspension parts for damaged and/or worn out parts and replace
them as necessary.

This is the only Land Cruiser Specs I could find, hope it helps

Can u plz give an idea how to convert Toe in from mm or inch to degrees? because my Wheel alignment machine takes input of Toe-in in degrees.

Castor angle is not easily measured directly, but it can be deduced by some simple 

calculations. Since the castor angle results from the steering swivels being inclined 

from the vertical, the measured camber angle changes as the wheel is turned. Thus 

measuring the change of camber angle over a measured range of steering angles allows 

calculation of the camber angle.

キャスター角は簡単には、直接測定ではありませんが、いくつかの簡単な計算で推定することができます。

Caster angle is not easily measured directly, but it can be deduced by some simple calculations.

ステアリングからのキャスター角の結果が垂直から傾いている旋回ので、ホイールとして測定キャンバー角の変更が有効になっています。

このように角度をステアリングの測定範囲でキャンバー角の変化を測定するキャンバー角の計算をすることができます。

したがって、1つの測量範囲のかじ取り角でキャンバ角の変化を測定すると、キャンバ角の計算は許容されます。

各フロントホイールを詳細に手順を説明し、数のウェブサイトがありますが、基本的に私が中心にキャンバー角とステアリングの両極端を測定します。私はまた、それぞれの位置でホイールとのワークショップの床に平行に線をマークします。これは、操舵角の正確な測定を可能にします。
There are a few websites which describe the procedure in detail, but basically for each front wheel I measure the camber angle at centre and two extremes of steering. I also mark a line on the workshop floor parallel with the wheel at each position. This allows an accurate measure of the steering angle.

The relevant formula is then :-

Caster = (180 / pi) * (camber1 - camber2) / (steer1 - steer2)

If you can steer 30 degrees either side of straight ahead, then the Castor angle is simply the difference between the camber angle at these points. 

The change in camber angle should be measured independantly for each wheel, to expose misalignmen

I used this method of caster angle calculation when I installed a set of castor correction radius arms, to correct a low castor angle in my Ibex due to lifted suspension. Before fitting the new arms, I measured 1.0 / 1.0 caster (L/R). With the new arms fitted I measured 3.0 / 3.5 degrees. (My measurement system has a resolution of 0.5 degrees).

If you use these procedures to align your vehicle, remember this info is worth precisely what you paid for it - nothing! If you disagree with anything I've written, or can spot any glaring mistakes or omissions, please let me know.

このモデルでは、サスペンションの減衰と剛性を変更する影響をシミュレートし、それにより、乗り心地と性能間のトレードオフを調べることができます。一般に、レーシング カーはバネ剛性が非常に高く、減衰係数が高いのに対して、乗用車のバネはより柔らかく、振動応答性がより高くなります。
