MOUNTING CONSTRUCTION of the DRIVING
AGGREGATES in MACHINES with a MOTOR DRIVING
Field of technics
The invention described below is in the field of motor industry.
It relates to the way the operating aggregates (engines,
reduction gears and transmission mechanisms) are fixed in
moving machines of all motor types, where the moving forces
and their reactions affect the stability, controllability and
passability of the vehicle whilst in motion.
Preceding state of technics
The currently known solution to fixing the operational
aggregates in the construction of motor vehicles use forth,
rear or centrally located engines with forth, rear or fourfold
transmission. In all these cases the operational aggregates
are fixed relatively mobile by means of soft connection
(dampering tampons), which allow a certain range of angular
and/or linear shifting of the operational mechanisms toward
the' carriage.
One of the solutions [1] known is where in an automobile with
a self-carrying carriage the crosswise operational aggregate,
the front and the rear axles are elastically connected. At the
same time, the operational aggregate and the motive bridge
form a junction; whilst the operational aggregate is connected
through elastic connecting elements to a carrier, forming a
junction with the non-motive bridge. The elements connecting
the operational aggregate and the carrier are located in the
lower part of the operational aggregate. The carriage is
connected to the operational aggregate through elastic
dampering elements located at the upper part of the

PCT/BG2007/000020
2
operational aggregate. This allows for little respective
movements into direct or vertical axis between the operational
aggregate and the carriage.
= However, all known methods for fixing allow the forces of the
reactions formed against the motion to be partly transmitted
into the same direction onto the entire vehicle, thus causing
the whole compartment or the frame to incline forward,
backward or to one side.
Technical essence of the invention
The purpose of this invention is to fix the driving aggregates
in machines with motor driving in such a way that not only
minimizes or neutralizes the forces, which form during motion
and acceleration against the moving forces, to prevent
destabilization of the automobile; but also to become an
actively operating pressure force directed towards the earth
only and stabilizing the accelerating vehicle.
This is achieved through a method of fixing, where a
randomly located (transverse or longitudinal) leading block
and the carriage of the vehicle are connected through elastic
(relatively mobile) soft connections.
The driving aggregate is the main transmission or any other
combination between the main transmission, engine and gear
box.
The assembly of driving aggregates is fixed to the carrying
elements of the vehicle through joints to a carrying frame,
fixed to the carriage elements through tampons, so that to
allow for a rotary movement with a rotation centre coinciding
or located very close to the rotation axle of the leading shafts
of the vehicle. A pre-strained torsion is mounted to the
leading block in the section where it rotates down to the road

surface during its relatively rotating movement at
acceleration. The torsion is mounted movably at its two ends
through pressing upon two inflexible shoulders, fixed to
movable elements of the suspension part, between the points
of fixing of these shoulders to the movable elements of the
suspension and the rotation points of the levers, turning
opposite the direction of the reaction forces and transmitting
the pressure force (directed towards the road surface) to the
compartment.
The other end of the driving aggregate when moving
backwards is limited in its movement downwards by a
bearing, mounted between the driving aggregate and the
carriage of the vehicle. Two levers are connected to the same
end of the aggregate, which at their opposite ends are
mounted through connection with horizontal freedom to hard
elements of the carriage. The points of rotation of the two
levers are secured to remain immovable in their space
section towards the elements of the carriage of the vehicle by
solid shoulders, fixed to movable elements of the suspension.
The solid shoulders are mounted to the movable elements of
the suspension of the vehicle by joints, located at a distance
before the respective ends of the solid shoulders, thus these
ends overlap the body of the movable parts of the suspension
elements and limit the rotation of the solid shoulder.
The advantages of the described solution rest with the fact
that these mechanical lever's system transforms the forces of
reaction which destabilize the vehicle into pressurizing and
stabilizing forces, acting only towards the road surface and
increasing the stability of the vehicle during acceleration of
any size and sign.

In this way, during acceleration the cohesion between the
tires and the road surface increases temporarily, thus
improving the starting and the acceleration period; the
controllability and the stability during turns; decreasing the
breaking distance and safety.
Description of the attached figures
Figure 1 shows the fixture from the side.
Figure 2 shows the fixture from above.
Examples for realizing the invention
A sample realization of the invention is illustrated at the
figures which show a scenario where the driving assembly 17
is located at the rear bridge between the driving wheels.
The fixing is done by frame 1, stabilized through tampons 2 to
solid elements 16 of the carriage of the vehicle. Fixing of the
driving aggregate 17 to frame 1 is done by joint connections 3
and 26 so that the rotation centre 4 of the driving aggregate
17 is close to or coincides with the axle of rotation of the
driving shafts 5.
A pre-strained torsion 15 is mounted to this part of the driving
aggregate 17, which during the relatively rotating motion
rotates towards the road surface. At its two ends the torsion is
mounted movably, but through pressing upon the solid
shoulders 10 and 21 between their rotation points 9 -11 and
20-22.
The other end of driving aggregate 17 is limited for rotating
towards the road surface by a bearing 6, mounted between
the driving aggregate and the carriage of the vehicle. At the
same end of the aggregate 17 levers 7 and 18 are mounted
with sliding connections 27 and 28. The levers 7 and 18 are

fixed with connections 8 and 19 with horizontal freedom to power elements
13 and 25 of the carriage. Levers 7 and 18 are located at the opposite
directions from the driving aggregate 17 to the side zones of the powered
elements of the vehicle construction. The rotation centers 9 and 20 of the
levers 7 and 18 are not connected to the compartment or the carriage.
Their stability towards the elements of the carriage of the vehicle is
secured respectively by the solid unbending shoulders 10 and 21, which
are fixed to the carriers 14 and 24 with joints 11 and 22 located at a
distance before the respective ends 12 and 23 of the solid shoulders 10
and 21, so that the ends 12 and 23 are overlapping at the respective
movable elements of the suspension - carriers 14 and 24.
Practical implementation of the invention
This invention can be applied to the existing vehicles - sport's, passengers,
with high possibility (off road), special and other vehicles.
At minimal rotation tendency of the respective end of the driving aggregate
17 to the road surface, the torsion presses to the earth the movable
elements 14 and 24 with the solid shoulders 10 and 21 as a result of the
excess pressure, thus temporarily increasing the cohesion of the tires with
the road covering.
At the same time the other end of the driving aggregate 17 tends to lift as a
result of the rotation tendency, thus putting tension over the ends 7 and 18
into upwards direction. At this stage the rotation centers 9 and 20 of the
levers 7 and 18 remain steady towards the other elements of the vehicle'
carriage due to the way the solid shoulders 10 and 21 operate, with ends
12 and 23 over mobile elements 14 and

24. This on its turn creates trend for shifting towards the road
surface of the other ends of the levers at points 8 and 19 and
thus create a pressure force upon the power elements 13 and
25 from the carriage, directed downwards to the road surface,
which on its turn creates rotation of the entire compartment
around the axle 4 of the leading shafts 5 so that the opposite
bridge of the vehicle will also press to the earth and will
increase the cohesion of the tires with the road surface. The
operation of the mechanical construction described is based
on the operation of the impulses, growing up temporarily at
tendency for changing the speed (acceleration).
Thus, simultaneously with the process of acceleration, both
bridges of the vehicle tend to move down temporarily or press
the road surface ¨ the engine bridge, respectively the driving
wheels, due to the pressure from the torsion lever 15, the
other bridge ¨ due to the tendency for lowering caused by the
pressure from levers 7 and 18.
In addition to this, whilst in motion on uneven surface or/and
curved trajectory the driving aggregate 17 under the
pressures arising between it and the torsion 15 transmits
upon the entire compartment through its front bearing 6
longitudinal rotation momentum with centre ¨ the rotation
center 4 at the point of the bearing 3 of the driving
aggregatel 7.
Such a method of fixing is applicable for the main
transmission block and/or the differential in the cases when
they are not fixed together in a joint body with the engine ¨ for
example, in vehicles where the engine is situated in one of
the bridges and the driving wheels at the other bridge.
