How much do the slip angle differ from the toe angle in a Truck?
How much do the slip angle differ from the toe angle in a Truck?
(OP)
Say a truck has 0.1 degree of Toe, driving at 80 km/hr in a straight line.
Would it be safe to assume that the Slip is 0.1 degree? I used vehicle dynamics theory Kiencke and personally do not think it is the case see attached image.
Curious about your ideas.
Thank you,
Yosef

RE: How much do the slip angle differ from the toe angle in a Truck?
Thanks a lot for the reply, appreciate it. I have added an explanation and 3 hypothesis for more clarity.
The picture on the right is supposed to show a truck with two different toe angles δ. The pictures to the right show the slip angle α and toe angle δ zoomed in on the upper left wheel.
Hypothesis:
In reality when the two toe angles are different, the resultant speed vector of the whole vehicle is not straight and as a result the toe and slip is not equal.
Hypothesis 2:
When simulating, it is ok to consider slip = toe angle since in reality the difference between the two angles are very small.
Hypothesis 3:
Slip and toe angle in straight driving are between 0.08 and 0.2 degrees.
