What kind of wheeled vehicle suspensions are there?
What are some characteristics?
single leaf spring (for lighter vehicles)
multi leaf spring (for heavier vehicles)
dry friction between leafs —> no need for additional dampers (but decreases comfort)
coil springs with one axle (with shock absorbers)
frictionless —> need for additional damping devices
coil spring on each wheel
more parts —> more expensive
McPherson strut suspension
less number of control arms (one instead of two)
—> it’s possible to “fix some degrees of freedom” (transfer moments and forces from frame to control arm and then to wheel)
What kind of wheels are there?
directional mud and snow tread (“self-cleaning” due to bending/ deformation)
advantageous rotation —> good traction
nondirectional mud and snow tread (“self-cleaning”)
for off-road AND roads
cross-country tread (look like the above but thicker)
rounded shoulder
not for off-road/ military vehicles:
Earthmover tread has also self-cleaning and is nondirectional
What is more important for decreasing the rolling resistance (F_o): increasing radius or increasing the width of the tire?
It is more important to increase the radius to decrease the rolling resistance
Which parameters does F_x = F_R depend on?
n, k_c, k_phi
not: c, phi, k (from Hanamoto)
