Description

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 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 heels 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 aggregated.

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.
