HMMWV Description

	The AM General Hummer has 2x2 seating on each side of the drive
train which is in midship position allowing the front
differential to be raised.  This together with the geared hubs,
provides a ground clearance of 0.4 meter.  The location of the
crew on each side of the drive train also allows a low center of
gravity.  The windshield frame is strong enough to serve as a
roll bar and support for various equipment kits.  Other pillars
also make the ballistically-protected weapon station inherently
strong and steady location on which to mount a variety of weapons
such as TOW, 7.62 mm, 12.7 mm and Mk19 40 mm GL.  At the rear the
cargo bed is large enough to accommodate an shelter without
overhang.

	To reduce life cycle and initial procurement costs, standard
automotive components are used wherever possible, as in the
transmission, transfer case, brakes and steering.

	The independent suspension, front and rear, gives good
manoeuverability, ease of handling and part commonalty.  The
geared hubs give 0.4 m all-round ground clearance incorporating
raised axles for high speed operations on road and across
country.  They also provide a 1.92 to 1 torque output
multiplication at the ground.

	The suspended carrier front and rear axles are identical, have
differentials and are mounted high directly in the chassis frame. 
The front propeller shaft has double cardon joints and the rear
propeller shaft has single cardon joints which give minimal
motion, improved torque characteristics and higher reliability
with resultant lower support costs.  Vehicle handling is enhanced
by the front stabilser bar being attached to the lower control
arms and pivot bracket reducing shock from the lower A-frame
member to the chassis.
