Definitions
- the present invention refers to a device for driving auxiliary apparatuses at a vehicle, which is equipped with a drive source, which auxiliary apparatuses for instance can incorporate a generator for generating electric current, cooling agent compressor for air conditioning installation in the vehicle, lubricating oil pump, water pump and cooling fan for the cooling system of the drive source, servo- mechanisms for controlling clutch, steering and brakes, etcetera, which device incorporates a hydraulic system with a pump for pressurizing the hydraulic system, whereby each one of the auxiliary apparatuses is connected to a hydraulic driving motor.
- auxiliary apparatuses e.g. water pump, oil pump, generator, steering servo-mechanism, air conditioning and starter motor and other.
- auxiliary apparatuses are driven by means of a belt transmission (having a high efficiency in itself) or e.g. by a chain transmission, at a varying operating speed, related to the motor speed.
- the mean efficiency of the generator normally can reach about 40-55 percent.
- the losses of the generator refer i.a. to friction losses, the air cooling, copper and iron losses and rectifier losses if the transfer is made from alternating current to direct current.
- a generator can be optimized with respect to the efficiency in several different modes, e.g. in that it is provided with permanent magnets, in that outer or inner cooling fan can be substituted e.g. by fluid cooling which permits heat energy recovery and in that components therein are optimized for a certain given operating speed.
- outer or inner cooling fan can be substituted e.g. by fluid cooling which permits heat energy recovery and in that components therein are optimized for a certain given operating speed.
- the cooling agent compressor of the air conditioning device This refers generally also to most of the other occurring auxiliary apparatuses.
- WO91/10575 From WO91/10575 is known a hydraulic system for the entire vehicle, including a hydraulic tank. A micro processor controls a valve which causes the pump to create a constant pressure in this tank. The same processor controls also a valve between the tank and the consumptive hydraulic motor. Otherwise however the system lacks "intelligence", it does not consider expected occurances, etcetera. The system is not mainly aiming at increasing the effectivity of energy use, does not in any way intend to raise the efficiency of separate auxiliary apparatuses included.
- DE 1143673 refers to a hydrostatic auxiliary driving device, which lacks control and adjustment system with individual influence on all auxiliary apparatuses and individual possibility of adaption of the speed for raising the efficiency.
- DE 4308113A1 discloses a possibility to arrange all in a bigger block. There is no possibility for individual speed adaption (for increasing the efficiency) or control/adjustment means for obtaining this.
- a purpose of the present invention is to provide a device for driving of auxiliary apparatuses, by means of which the above described drawbacks can be reduced.
- the device is characterized in that the driving motors of the auxiliary apparatuses are equipped with control and adjustment means, respectively for connection and complete or partial disconnection of these in dependency of the effect consumption of the driving motors, that the control and adjustment means are arranged to communicate with a control computer, for adaption of the effect of the drive source to expected changes in the effect consumption of the auxiliary apparatuses . And that said speed range is specific for each auxiliary apparatus and its driving motor.
- FIG. 1 schematically and in block form shows a drive system according to the invention
- Fig. 2 in perspective shows an installation of the invention at a drive source.
- the reference numeral 10 refers to a drive source, e.g. a combustion engine, which can act directly or via a transmission for propelling a vehicle.
- a drive source e.g. a combustion engine
- passenger cars, buses and lorries can be mentioned passenger cars, buses and lorries.
- An output shaft 11 of the motor 10 can be connected to a transmission 12, which adapts the speed in appropriate manner.
- the transmission 12 in turn is connected to a hydraulic pump 13, which operates according to the principle of a variable displacement .
- this can deliver a substantially constant flow of hydraulic fluid or a hydraulic fluid flow of a constant pressure to a hydraulic circuit 14, independent of the speed of the drive source 10.
- the high pressure side of the hydraulic circuit 14 is designated 15 and the low pressure side 16.
- a pressure vessel 17 for storing hydraulic pressure can be connected to the high pressure side 15 of the circuit.
- a number of hydraulic motors 18 are connected to the hydraulic system either in series or in parallel or in a combination of series/parallel connections. Each one of these hydraulic motors 18 is connected to one or more auxiliary apparatuses 19.
- the auxiliary apparatuses can for instance be a generator for generation of electric current, a cooling agent compressor for an air conditioning device in the vehicle, lubricating oil pump, a water pump and a cooling fan for the cooling system of the drive source, servo-mechanisms for manoeuvering of clutch, steering and brakes, etcetera.
- All hydraulic motors 18 work e.g. according to the principle of fixed displacement, which means that they can operate within a mainly constant speed range. Alternatively they can operate at a variable displacement.
- auxiliary apparatuses can be optimized for this speed range, which means that their efficiency can be raised substantially in comparison to if their speed should be entirely dependent upon the speed of the drive source 10. For instance it is possible to achieve a mean efficiency of more than 90 percent, at a generator for generation of electric energy, if it is optimized for a certain speed range .
- auxiliary apparatuses Different operating speeds can be achieved hereby by choice of hydraulic motor or by appropriate control/adjustment thereof.
- a transmission e.g. a gear unit 20 or a belt transmission, which is connected between an auxiliary apparatus connected to the hydraulic motor and another auxiliary apparatus.
- the hydraulic system incorporates control and adjustment valves 21, which can be manoeuvered mechanically, electrically, pneumatically, hydraulically or with a combination of one/some of these methods for connection or disconnection or successive (gradual) connection or disconnection of hydraulic motors associated with different auxiliary apparatuses.
- Hydraulic motors can hereby be disconnected or partly disconnected at manoeuvres that are power requiring for the vehicle, e.g. at acceleration for overdriving, or be adjusted to a lower level .
- the drive source could be instructed to increase its speed/output upon suborders depending on expected occurances in the system.
- the air conditioning system can call for more of the drive source when the cooling compressor is required to start/increase the effect.
- the system described above further makes possible a complete integration of hydraulic pump, hydraulic motors, generator, water pump, cooling ducts etcetera in the form of casing integration with the drive motor.
- a compact auxiliary apparatus package Except for from energy aspects, this might also be an advantageous solution in view of lower space requirements and crash safety.
- More than one auxiliary apparatus can be driven by the same hydraulic motor if so is desired and if desired operating speed permits it, e.g. via a common shaft or via appropriate power transmission.
- the pressure vessel 17 can e.g. be used as an energy storage, for use when extra power is needed, e.g.
- the stored energy can also be used for steering servo-mechanisms and for start of the drive source.
- Energy can be stored in the pressure vessel 17 when there is an excess, e.g. when the vehicle has a torque excess (brake energy recovery) or when the drive source has a torque excess or its best efficiency.
- the system described above gives also a possibility to recover cooling effect from the hydraulic components and the auxiliary apparatuses and to transfer this to the parts of the vehicle and/or its drive source where it can be utilized.
- An example of this is integration with the cooling system of the drive source in order to reach a proper operating temperature rapidly and for facilitating heating of the compartment areas of the vehicle .
- Fig. 2 shows a transverse drive source 10 as seen obliquely from the front and equipped with gear box 22.
- An integrated hydraulic unit 23 incorporating pump and hydraulic system is positioned just above the gear box 22.
- the hydraulic unit 23 in turn supports a number of auxiliary apparatus units 24, each one of which can incorporate a hydraulic motor 18 and at least one auxiliary apparatus 19.
- the auxiliary apparatuses can be positioned in advantageous positions in the vehicle and they may easily be connected by means of e.g. channels, tube conduits or high pressure hoses.
- common cooling/heating ducts in the hydraulic unit 23, the auxiliary apparatus unit 24 and the drive source.
