Abstract

The system is to be installed on a vehicle chassis and comprises a dedicated internal- combustion engine, an electric generator, an electric converter and an electric motor designed to drive each hydraulic and/or pneumatic pump of the system to actuate the equipment for collecting and/or compacting refuse. In operating conditions, the electric motor receives electrical energy supplied by the electric generator via the converter, which enables a wide variation in the r.p.m. and in the load of the internal-combustion engine irrespective of the conditions of use of the hydraulic and/or pneumatic means necessary for operation of the equipment for collecting and/or compacting refuse.

Description

SYSTEM TO ACTUATE EQUIPMENT FOR COLLECTING AN/OR COMPACTING REFUSE
The present invention relates to the sector of collection and/or compacting of refuse obtained by means of equipment appropriately installed on vehicles and regards an autonomous system that is independent of the engine that drives the vehicle on which it is installed and is designed to move the equipment for collecting and/or compacting refuse, drastically reducing the atmospheric and acoustic pollution caused during said operations for collecting and/or compacting refuse.
More in particular, said autonomous system comprises: an internal-combustion engine of its own; an electric generator; an electric converter and an electric motor for moving the hydraulic and pneumatic means of a known type, which necessary for actuating the equipment for collecting and/or compacting refuse.
Currently, the vehicles on which equipment is provided for collecting and/or compacting refuse normally use the engine designed for driving the vehicle for supplying fluid under pressure to the system that manages operations for collecting and/or compacting refuse.
In other words, the vehicle engine itself supplies the power necessary for moving said equipment and supporting it up to completion of the operations .
A first disadvantage is that the engine, controlled by a regulation system, operates at constant r.p.m., at the lower limit of the range of use, with markedly variable torque and hence in non-optimal conditions as regards release of pollutant emissions from the exhaust . A second disadvantage is represented by the fact that the operation of the equipment for collecting and/or compacting refuse is accompanied by acoustic emissions of a high level such as to constitute a source of considerable disturbance in the surrounding environment, above all during night hours. Said acoustic emissions are originated, in the first place, by the high values of the pressure of combustion due to the fact that the hydraulic equipment is usually controlled via pumps moved by a power offtake of the engine of the vehicle. Said engine presents conspicuous displacement and is forced to function at low r.p.m. and high torque.
In the second place, to operate in said conditions it is necessary to resort to systems of regulation of the r.p.m. that lead to an oscillation or hunting in the r.p.m. itself, which, even though of minor degree, causes the acoustic emission to be particularly troublesome .
Consequently, the main purpose of the present invention is to overcome said disadvantages by providing a system designed to move the equipment for collecting and/or compacting refuse that is to be installed on a vehicle, said system being completely separate from the engine for driving said vehicle and being able to move the means for collecting and/or compacting refuse, reducing drastically both the acoustic pollution and the release of pollutant' emissions from the exhaust.
The above purpose has been achieved, according to the present model, envisaging a system comprising in combination:
- a dedicated internal-combustion engine;
- a current generator;
- a possible electric converter; and
- an electric motor designed to move each of the hydraulic and/or pneumatic pumps provided in the system for moving the equipment for collecting and/or compacting refuse.
In operating conditions, the electric motor is supplied by the electrical energy that is supplied by the electric generator, preferably via the converter that enables a wide variation in the r.p.m. and in the load of the internal-combustion engine irrespective of the conditions of use of the known hydraulic and/or pneumatic means necessary for operation of the equipment for collecting and/or compacting refuse, which are moved by said electric motor.
The current generator is moved by the dedicated internal-combustion engine.
In other words, the mechanical power supplied by said system to the hydraulic and/or pneumatic means does not come from the engine for driving the motor vehicle, but from a dedicated internal-combustion engine that is independent of the previous one.
A better understanding of the model will be obtained from the ensuing detailed description and with reference to the attached figures, which show, purely by way of example, a preferred embodiment thereof. In the drawings :
- Figure 1 shows a simplified diagram of the functional parts of the model. In the preferred embodiment, which is described herein and illustrated in Figure 1, a system is envisaged comprising a dedicated internal-combustion engine 1, an electric generator 2, an electric converter 3, and an electric motor 4. In operating conditions, the electric motor 4 is supplied by the electrical energy supplied by the electric generator 2, via the converter 3, whilst the generator 2 is set in rotation by the internal- combustion engine 1. The electric motor 4 converts the electrical energy into mechanical energy and transfers it to the known hydraulic and/or pneumatic means designed to move the equipment for collecting and/or compacting refuse.
According to a peculiar characteristic of the invention, in order to enable the internal-combustion engine 1 to perform a wide variation in the r.p.m. and in the load irrespective of the conditions of use of the hydraulic and/or pneumatic means, the electric converter 3 is set between the electric generator 2 and the electric motor 4 and functions as rectifier/inverter .
In other words, with this solution the converter 3 thus enables running of the internal-combustion engine 1 at a high r.p.m., reducing evidently the engine displacement necessary for supplying the power required and hence the overall dimensions. A first advantage is that the engine for driving the vehicle on which said system is installed can be maintained at an idling r.p.m., or even turned off, during the operations for collecting and/or compacting refuse, so evidently reducing the consumption thereof and the release of pollutant acoustic and gaseous emissions in so far as the equipment for collecting and/or compacting refuse is actuated by means of the mechanical power supplied by a dedicated internal- combustion engine 1.
A second advantage is that said dedicated engine 1 can have reduced dimensions such as to enable it to be confined in a structure with high acoustic insulation in order to attenuate the noise even further. A third advantage is represented by the fact that the reduced overall dimensions of the model make possible adoption of an architecture that enables a rapid and convenient hydraulic, pneumatic and electrical connection with the corresponding systems installed on board the chassis of the vehicle and with the working equipment in their commercial configurations, as well as enabling a convenient offline maintenance.
Furthermore, the fact of not using a power offtake on the engine for driving the vehicle reduces wear and damage to the gear-change of the vehicle itself.
Again, said motors 1 prove more easily adaptable to the use of fuels, whether liquid and/or gas, characterized by a lower release of pollutant exhaust emissions.
Further benefits regard the advantages that .can be achieved in terms of acoustic emissions (mechanical noise of combustion and aerodynamic noise at intake and exhaust) in so far as the motor 1 operates at variable r.p.m., enabling optimization of the point of operation thereof to render it more acceptable for use in built- up areas .
The present model has been described and illustrated according to a preferred embodiment thereof, but it is evident that a person skilled in the sector can make modifications and/or replacements that are technically equivalent, without thereby departing from the sphere of protection of the present industrial patent right.
