Description

The The present invention relates to the field of collection and / or compaction of garbage, which is achieved by means suitable for vehicles is installed; and relates to a self-contained system, the independently is from the engine that powers the vehicle on which it is installed is, and which is designed to the device for collecting and / or Compacting garbage to move by the while the operations For collecting and / or compacting garbage caused atmospheric and acoustic pollution is drastically reduced.

special includes the self-employed System: its own internal combustion engine, a generator, a electrical converter and an electric motor for moving the to Operation of the device for collecting and / or compacting waste necessary hydraulic and pneumatic devices of a known type.

Currently use the vehicles to which a device for collecting and / or compacting of garbage is provided, usually the engine that drives the vehicle is designed to supply pressurized fluid to the system, the operations to collect and / or compact garbage.

With In other words, the vehicle engine itself provides the power to move the equipment necessary and keeps it up to the end of the operations in progress.

One first disadvantage is that the controlled by a control system Engine at constant speed, at the lower limit of the range of use, with significantly fluctuating torque and thus not optimal Conditions works, causing the release of pollutant emissions from the exhaust system concerns.

One second disadvantage is represented by the fact that the operation the device for collecting and / or compacting of waste through Sound emissions accompanied by high levels, which is a significant interference source in the surrounding area, especially during the night hours. These sound emissions come first by the high values the combustion pressure caused due to the fact that the hydraulic device is usually controlled by pumps, which is driven by a power take of the vehicle engine become. This engine has a remarkable displacement and is forced at low speeds and high torque to work.

Around working in these conditions, second, it is necessary to resort to systems for controlling the speed, resulting in a fluctuation or to level the speed itself, which causes, even if to a lesser degree that the sound emission is particularly unpleasant.

consequently the main purpose of the present invention is to overcome these disadvantages by providing a system to overcome that designed is to be installed on a vehicle device for Gathering and / or compacting garbage, using the system Completely disconnected from the engine to propel the vehicle and capable of to move the device for collecting and / or compacting garbage, by both the sound emission and the release of pollutant emissions be drastically reduced from the exhaust system.

• – einen zugeordneten Verbrennungsmotor;
• – einen Stromerzeuger;
• – einen möglichen elektrischen Umformer; und
• – einen Elektromotor umfasst, der so ausgelegt ist, um jede der in dem System zum Bewegen der Vorrichtung zum Sammeln und/oder Verdichten von Müll vorgesehene Hydraulikpumpe und/oder Pneumatikpumpe anzutreiben.

The above-mentioned purpose has been achieved according to the present model by introducing a system which, in combination:

• - an associated internal combustion engine;
• A generator of electricity;
• - a possible electrical converter; and
• An electric motor adapted to drive each of the hydraulic pump and / or pneumatic pump provided in the system for moving the waste collecting and / or compacting device.

at Operating conditions, the electric motor by the electric Power supplied by the power generator preferably via the Supplied converter which is a wide fluctuation of the speed and load of the Internal combustion engine allows; independently from the operating conditions of the for the Operation of the device for collecting and / or compacting refuse necessary known hydraulic and / or pneumatic devices that be driven by this electric motor.

Of the Power generator is driven by the associated internal combustion engine.

With In other words, the hydraulic and / or pneumatic devices fed through this system Mechanical energy does not come from the engine to drive the motor vehicle, but from an associated internal combustion engine that is independent of the previous one is.

better understanding of the model will become apparent from the detailed description below and with Reference to the attached Figures obtained exclusively show a preferred embodiment of the same by way of example.

In the drawings:

shows 1 a simplified graphical representation of the functional parts of the model.

In the preferred embodiment described herein and in 1 A system is envisaged which has an associated internal combustion engine 1 , a power generator 2 , an electrical transformer 3 and an electric motor 4 having.

Under operating conditions, the electric motor 4 powered by the electrical energy coming from the generator 2 via the converter 3 is fed while the power generator 2 through the internal combustion engine 1 is set in rotation.

The electric motor 4 converts the electrical energy into mechanical energy and transfers it to known hydraulic and / or pneumatic devices designed to drive the device for collecting and / or compacting refuse.

Thus the internal combustion engine 1 can operate at a wide variation of speed and load regardless of the operating conditions of the hydraulic and / or pneumatic devices, according to a particular characteristic feature of the invention, the electrical converter 3 between the generators 2 and the electric motor 4 set and works like a rectifier / inverter.

In other words, this solution allows the converter 3 thus the operation of the internal combustion engine 1 at high speed by significantly reducing the engine displacement required to supply the required power, and thus the overall dimensions.

A first advantage is that the engine for propelling the vehicle on which the system is installed can be maintained or shut off during operations for collecting and / or compacting refuse at idling speed, consumption thereof and release of pollutants To significantly reduce noise emissions and gaseous emissions, in that the device for collecting and / or compacting refuse by means of the mechanical power is put into operation by an associated internal combustion engine 1 is supplied.

A second advantage is that the associated engine 1 reduced dimensions, so that it is possible to include it in a structure with high sound insulation to further attenuate the sound.

One third advantage is represented by the fact that the reduced Overall dimensions of the model make the assumption of a design possible, the fast and convenient, hydraulic, pneumatic and electric Connection with the installed on the chassis of the vehicle, corresponding Systems and with the working device in their commercial versions allows as well as an independent from the plant working, convenient maintenance possible.

Of Further reduces the fact, no power take-off on the engine to use for driving the vehicle, wear and damage to the gearshift of the vehicle itself.

Again it turns out that the engines 1 are more easily adaptable to the use of fuels, either liquid and / or gas, which is characterized by a lower release of pollutant emissions.

Further benefits relate to the advantages achieved in terms of sound emissions (mechanical noise of combustion and aerodynamic noise at the cylinder inlet and cylinder outlet) in so far as the engine 1 operating at a variable speed, which allows for optimization of its operating point to make it more reasonable for use in built-up areas.

The present model has been according to a preferred embodiment described and illustrated, but it is clear that a specialist in this sector will make modifications and / or substitutions which are technically equivalent without thereby departing from the scope of protection of the present Industrial Patent Law.
