11 claim.- (or. zen-104)
The present invention relates to ‘a vehicle
chassis provided with means for compensating
for uneven tracks of roadsffor‘vehicles .of all
types, especially for 'motor driven or drawn ve
springs 6, the opposite ends of which abut on lugs
5 hicles‘ and for vehicles drawn by animals.
, According to the present invention, the vehicle 49 of the longitudinal struts ‘I, so that the 5
axle
'
springs are compressed when the wheels I9 swing
upward. Each of the four wheels I8 and I9 is
therefore independently swung. A pin ‘I is se
cured to the tubular supporting rail 2 and forms
a pivot for a two-armed lever 8. The front axle 10
assembly 3 and rear axle assembly 4 are con
. nected to the lever B by the respective ball-joint
pins 9 and Ill. The sleeve II of the front axle
assembly and the sleeve I2 of the'rear axle M
-sembly are‘slid onto the tubular supporting rail 15‘
rail which forms a part of the body supporting
2 before the front and rear struts I3 are at
frame and supports theframe superstructure and
tached to it. for example by screwing, so that
which connects thetwo axle assemblies. ,
2o - The body supporting frame always takes up a
the rail 2 is supported on the axle assemblies.
The sleeves I I and I2 are lined or coated at the
middle position when the‘ axle assemblies are _ bearing positions with a layer of ?bre, asbestos 00,
or the like which is inserted so. as to hecapable “
locked in relation to one another, and it is there
by possible to overcome the greatest obstacles in
open country with relatively'small upward swing
” ing of the wheelsin relation to. the body support
ing frame, without the wheels encountering the
body supporting frame and without altering the
wheel pressure of the individual wheels. ‘ -
by way of example in the
accompanying drawing, in which_
Figures 1, 2, and 3 are, respectively, a side
elevation,v a plan’and-a front elevation of the
chassis.

The frame I- is supported, through the inter
mediary *of struts l3, on a central tubular sup-_
porting rail 2,'forming a unit hereinafter referred
to as the body supporting frame. The front axle
assembly 3 and the rear ‘axle assembly ‘4 are
) rockably mounted on the rail 2. , The front axle
between the tubular supporting rail 2 and the
sleeves II and I2 is thereby prevented and all
noises are damped. ‘Tightening of the sleeves I I 25
and I2 on the rail‘ 2 enables a damping action to
be effected by the ?bre or intermediate layer so
that if play occurs at the joint pins 9 and ID, or
at the pivot pin 1, quiet working of the body sup
porting frame I, 2, I3 is still ensured. The tight- 30
ening of the sleeves I I and I2 can be e?ected by
slitting them at the ends at 20, and clamping
them more or less tightly by screws or the like
in the manner of hand-cuffs.

.When travelling over obstacles, the front axle 35
assembly 3 is rocked relatively to the rear axle '
assembly 4 or vice versa, as is indicated in Fig
ure 3 by dot and dash lines, so that non-uniform
spring or wheel loads would ordina '
arise.
The compensating member 8 which is provided 40
between the axle assemblies 3 and 4, however, en
sures that all the wheels I8 and iii are always
II and by small links 32 to the axle body 3a, and Y subjected to equal wheel pressures, and that the
steering knuckles I4 swiveled on the yokes 33 and tubular supporting rail 2 and the'usupersia-ucture
provided with axles‘ Ma for the front wheels I8. I ?xed thereon are held in a central position in 45
