[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 63 / 560,225, filed March 1, 2024, the disclosure of which is incorporated herein by reference, and U.S. Patent Application No. 19 / 051,295, filed February 12, 2025, the disclosure of which is incorporated herein by reference.

[0002] FIELD OF THE INVENTION The present invention relates generally to multi-component auxiliary power systems and work vehicles including such multi-component auxiliary power systems. [Background technology]

[0003] Welding systems for electric welding, such as arc welding or MIG welding, require some kind of power source to provide the power necessary to drive the welding process. Typical welding systems obtain the necessary power directly from an AC or DC power source having a relatively stable waveform, which requires relatively simple circuitry to convert the power received from the power source into the stable waveform required for the welding process. Such systems are typically limited to very specific functionality and are used in specific locations because of the specific power source required. However, welders are often used in field environments where access to specific power sources is difficult and / or may lack certain functionality. Therefore, a welding system that provides additional functionality that may be required in a field environment and / or is less geographically restricted by access to a specific AC or DC power source is desirable.

[0004] To increase portability to the job site, welding systems are sometimes transported on work trucks. Work trucks are primarily used to perform work functions on the job site. When delivered from the automobile factory, trucks are configured simply to transport people and materials. To provide more specialized job site applications, it is common to modify basic work trucks, converting them from simple transport vehicles into specialized work trucks. Such converted work trucks are often modified by integrating additional mechanical components, such as generators, welding machines, and hydraulic cranes, into the truck's chassis and / or power and / or control systems. Optimization of components on work trucks typically centers around several key objectives, including weight reduction, space savings, increased uptime, and extended and / or streamlined maintenance cycles. Prioritization of these goals typically includes reducing the truck's overall weight, ensuring efficient space utilization, and increasing work uptime. Efficient design, including these measures for specific work truck designs, can contribute to a more versatile, resource-efficient, and reliable work truck system overall.

[0005] Specialized work trucks are often equipped with transmissions designed with a power take-off port, which couples to a gearbox called a power take-off (PTO) to provide a source of rotary power that can be coupled to other auxiliary systems via a rotating drive shaft, providing a gateway for imparting motive power to the auxiliary systems. PTO systems allow for the direct drive of a variety of machines and / or shafts, providing greater versatility and functionality to standard work trucks. However, PTOs and transmission PTO ports operate within strict constraints of space, torque, angular velocity (e.g., RPM), and power, which can limit the flexibility of their use with respect to the different types and / or numbers of machines that can draw drive power from the PTO system. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above, it would be desirable to have a system that can use energy from a single PTO drive of a work truck and use it to power a variety of different types of machines without requiring significant modifications to the system when switching between and / or simultaneously using machines requiring different forms of power, such as compressed air power, hydraulic power, and / or electrical power. [Means for solving the problem]

[0016] The present invention generally relates to a multi-component auxiliary power system and a work vehicle including such a multi-component auxiliary power system. The present invention will now be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. It should be understood that the various drawings are not necessarily drawn to scale, both between and within the same drawing, and in particular, the dimensions of components are arbitrarily drawn for clarity of illustration. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the invention. It will be apparent, however, that the invention may be practiced without these specific details. In addition, other embodiments of the invention may be realized, and the invention may be practiced and carried out in ways other than as described. The terms and phraseology employed in the description are used for the purpose of facilitating an understanding of the invention and should not be construed as limiting.

[0017] As used herein, "at least one," "one or more," and "and / or" are open-ended expressions used both conjunctively and disjunctively. For example, each of the phrases "at least one of A, B, and C," "at least one of A, B, or C," "one or more of A, B, and C," "one or more of A, B, or C," and "A, B, and / or C" means A only, B only, C only, the set of A and B, the set of A and C, the set of B and C, or the set of A, B, and C. All disjunctive words or phrases indicating two or more alternative items, whether in the description of embodiments, claims, or drawings, should be understood to contemplate the possibility of including one of those items, either of those items, or both items. For example, the phrase "A or B" should be understood to include the possibilities of "A" or "B" or "A and B."

[0018] In preferred, but non-limiting, embodiments, the multi-component auxiliary power system disclosed herein provides one or more mechanically coupled auxiliary power components, i.e., by way of non-limiting example, one or more air compressors, generators for welding and / or providing battery power, and / or hydraulic pumps, which are mechanically coupled to one another by one or more mechanical power transmission mechanisms. Such a power system is configured to receive mechanical energy from a primary rotary power source and distribute this power to one or more various auxiliary power components, which can convert the energy into a variety of different power types, e.g., compressed air power, hydraulic power, mechanical motive power, and / or electrical power, for use by a variety of different types of power machines. The multi-component auxiliary power system is configured to receive rotational kinetic energy from a primary rotary power source, e.g., a drive shaft or similar rotary drive linkage driven by a PTO or engine. The multi-component auxiliary power system may optionally include a generator powered by a through-shaft drive. The components within the multi-component auxiliary power system may be directly coupled to one another, e.g., by a direct drive shaft coupling, or may be coupled to one another via other mechanical power transmission mechanisms, such as gears, belts, clutches, and / or additional shafts. The multi-component auxiliary power system may optionally provide an additional power take-off (PTO) port as yet another auxiliary power component. In some non-limiting embodiments, the system may be configured to provide compressed air at various CFM and pressures, welding power waveforms, jump-start electrical waveforms, and battery charging electrical waveforms, and / or AC and / or DC export power. In some preferred configurations, the multi-component auxiliary power system may be specifically configured to be mounted on a work truck or similar vehicle having a PTO driven by the vehicle's primary combustion engine or secondary engine or other power system.The power system can be provided as a single unit, with its components securely attached to one another, for example by bolts, welds, threads, etc., that is configured to be mounted to and carried by the frame of the work truck below the truck bed deck, thereby freeing up deck space for other equipment and / or uses.

[0019] The integration of various power sources is achieved through the mechanical connection of multiple rotating machines (e.g., auxiliary power components). These machines provide the flexibility to operate independently, cooperatively, and / or in combination, all powered by a single prime mover (e.g., a work truck's engine and / or PTO). The system also simplifies safety systems by enabling centralized power shutdown. The system also typically streamlines control mechanisms for the various auxiliary power components. A common control scheme throughout the mechanically coupled system facilitates seamless integration with the prime mover, achieving objectives such as speed control and automatic start-stop functionality. This integrated, interconnected approach improves both the operational efficiency and safety of multi-component auxiliary power systems incorporating the principles of the present disclosure.

[0020] Referring now to the non-limiting embodiments illustrated in the drawings, FIGS. 1-4 illustrate an exemplary configuration of a multi-component auxiliary power system 10 (hereinafter sometimes simply referred to as a "power system") according to aspects of the present invention, configured for under-deck mounting to the frame of a work truck. However, it should be understood that power system 10 may be mounted in other manners and / or in other support and / or use configurations. Power system 10 includes a rotational power coupling, such as a drive shaft 12, a power transfer linkage 14, and a plurality of auxiliary power components operatively coupled to power transfer linkage 14, whereby rotational power of drive shaft 12 is converted by power transfer linkage 14 and distributed to one or more of the auxiliary power components. The auxiliary power components of power system 10 include a series of mechanically coupled power-converting rotating machines. In the non-limiting example illustrated in the figures, the auxiliary power components include an air compressor 16, a generator 18, and a hydraulic pump 20 (collectively referred to herein as auxiliary power components 16, 18, and 20). Power system 10 may be referred to as a PTO-driven compressor, a welder, a generator, and a hydraulic system. The auxiliary power components 16, 18, and 20 do not necessarily have to be assembled in the order shown in the figures, but may be arranged in any feasible layout that best meets the space needs of a particular use configuration.

[0021] Preferably, the drive devices have input and output speeds and torques that match what the mating machine can reliably accept and / or transmit. In some contemplated embodiments, the aggregate power demands of all rotating machines in power system 10 (e.g., auxiliary power components 16, 18, and 20) may be greater than the power output of the mechanical drive source (e.g., truck engine and / or PTO) driving drive shaft 12. In this case, auxiliary power components 16, 18, and 20 are preferably configured and controlled in a manner to function within the power limits of the prime mover / primary mechanical drive source, such as the primary or auxiliary engine of a mobile work truck.

[0022] The rotational power coupling between the prime mover and the power transfer linkage 14 may include at least one of a belt drive, a gear drive, a PTO drive, a hydraulic PTO drive, and / or an electric PTO drive. In the example shown in FIG. 4 , the rotational power coupling is a drive shaft 12, which is operatively coupled to a primary mechanical drive source on a mechanical power generation system. For example, the drive shaft 12 is coupled to a PTO port 24 on a work truck, and the mechanical power generation system includes a transmission 22 and PTO port 24 on the work truck that drive a PTO 26. In this example, the prime mover (primary mechanical energy source) for the system 10 may be either a primary internal combustion engine for the work truck or an auxiliary engine carried by the work truck. However, the power system 10 may be arranged in other installation configurations and / or use other types of prime movers. For example, the power system 10 may be configured for use with stationary power plants (e.g., stationary engines on fixed platforms), power plants on railroad locomotives, marine vessels, aircraft, trailers, etc. The drive shaft 12 may be single-part or multi-part. The drive shaft 12 may include any brackets and / or support mechanisms necessary to ensure proper fit, alignment, and longevity of the joint. While one driveline is shown, in some embodiments the drive shaft 12 may not be used, and other types of rotary power couplings may be used to provide a functional auxiliary power system 10. For example, the rotary power couplings may include direct, soft, hydraulic, and / or electrical couplings between the prime mover or mechanical drive source and the transmission 22 or other rotary power source, depending on the type of primary power source to which the power system 10 is operatively connected.

[0023] The power transfer linkage 14 is configured to transmit rotational energy from a rotary power supply to one or more different rotary drive auxiliary power components at a converted power level and speed appropriate for driving each particular auxiliary power component. The power transfer linkage 14 is connected to the drive shaft 12 (or other rotary power supply) by any suitable coupling, such that rotational power from the drive shaft 12 is transmitted to the power transfer linkage 14. For example, the power transfer linkage 14 may include a belt drive and / or a gear drive that functions to direct power through the mechanical linkage to the air compressor 16, the generator 18, and / or the hydraulic pump 20. In this particular, non-limiting exemplary configuration, the power transfer linkage 14 includes a first rotary power output at its rear and a second rotary power output at its front. The air compressor 16 and the hydraulic pump 20 are each directly connected to a different rotary power coupling on the power transfer linkage 14, and the generator 18 is directly connected to the air compressor. For example, the air compressor 16 may be mounted on the power transfer linkage 14 and driven by a first rotational power output of the power transfer linkage, and the hydraulic pump 20 may be mounted on the power transfer linkage and driven by a second rotational power output of the power transfer linkage. Thus, the air compressor 16 may be mounted on a first (rear) side of the power transfer linkage 14, and the hydraulic pump 20 may be mounted on a second (forward) side of the power transfer linkage opposite the first side.

[0024] The power transfer linkage 14 may provide torque reduction, torque multiplication, and / or rotational redirection from the drive shaft 12 to provide appropriate converted power to the respective auxiliary power components. The power transfer linkage 14 can be used to configure the power system 10 to convert mechanical rotational energy provided by a single power source (e.g., a "prime mover"), such as a work truck's primary engine, to provide one or more different types of drive, including, for example, a belt drive, a PTO drive, a hydraulic PTO drive, and / or an electric PTO drive. In the optional configuration shown in the figures, the power transfer linkage 14 includes a PTO pad 28 to provide alternative drive options. The PTO pad 28 can be used to provide power to a hydraulic pump 20 or a drive belt, gearbox, or other rotating equipment. One possible power transfer linkage is a PowerTech San-Gear gearbox, although other types of gearboxes and transmissions can also be used.

[0025] The air compressor 16 is driven by a drive coupling on the power transfer linkage 14. In this example, the air compressor 16 is attached directly to the PTO pad on the rear side of the power transfer linkage 14, opposite the drive shaft 12, by, for example, bolts or other fasteners or welding, to couple to the PTO drive. The air compressor 16 includes a through shaft 30, which provides rotational power to the generator 18. The air compressor 16 can be a rotary screw compressor, a piston-type compressor, or other type of air compressor. The air compressor 16 can be geared or gearless. In some configurations, the air compressor 16 can be used as an attachment point for a power system 10 secured to the frame rails of a motor vehicle, such as a work truck, tractor, or construction vehicle, or other framed application, such as a rail car or locomotive, truck trailer, watercraft, aircraft frame, or other support structure. In some preferred embodiments, the air compressor 16 is configured to generate pressure for positive displacement. In one embodiment, the air compressor is a Genair rotary screw air compressor available from Vanair Manufacturing, Inc., although other types of air compressors may be used.

[0026] The generator 18 includes a dynamo that converts rotational energy into electrical energy. In this example, the generator 18 is attached directly to the rear side of the air compressor 16, opposite the power transfer linkage 14, for example, by bolts, screws, and / or welding, and receives power from the generator's 18 through shaft 30. In other possible configurations, the generator 18 may be powered by a belt drive or other type of linkage to the air compressor 16, or by a direct connection to the power transfer linkage 14. In some non-limiting embodiments, the generator 18 is configured to provide one or both of an AC and / or DC power source suitable for powering various electrical loads, such as lights, tools, welding machines, battery chargers, and / or jumpers, or other electrical equipment. The generator 18 may include any appropriate generator and / or control circuitry desired for a particular application. In one exemplary arrangement, the generator 18 includes one or more of a welding machine, an AC power generation machine, and / or a battery charging machine. The generator 18 may be permanently energized or controlled via an external field manipulator.

[0027] Generator 18 can be arranged to provide nearly any type of power required. For example, generator 18 can be configured to provide single-phase or three-phase power at 50 Hz or 60 Hz frequency output, and / or single or multi-voltage power, such as, but not limited to, 120 V, 240 V, 208 V, or 480 V. Other output configurations are also possible depending on the required application.

[0028] The generator 18 may optionally include a battery charging system. Preferably, such a battery charging system is configured to support multiple charging algorithms, including algorithms configured to charge lead-acid batteries, lithium, and / or operating capacitors, allowing the battery charging function to be used with a variety of voltage and current source schemes. For example, the battery charging system may provide export power using battery charging profiles including lithium and / or lead acid chemistries. The battery charging system may provide export power that can be used directly to charge the battery and / or that can be used in conjunction with external power conversion and charging circuitry for battery charging.

[0029] Generator 18 may optionally include a jump start system that uses the starter motor voltage. The jump start system preferably provides export power that can be used to directly jump start vehicles, such as automobiles, trucks, boats, tractors, construction equipment, etc. In some embodiments, the jump start system may provide export power that can be used in conjunction with supercapacitor and / or other power storage or chopper board technology for advanced waveform generation and voltage manipulation.

[0030] Generator 18 may optionally include a welding machine, preferably configured to provide a welding waveform operation via field operation and / or operation of a chopper circuit, which may include significant addition of inductance and capacitance. Of course, other configurations for generator 18 are possible.

[0031] In this example, the power transfer linkage 14, air compressor 16, generator 18, and hydraulic pump 20 are all securely attached to one another, for example, by bolts, screws, and / or other types of fasteners, to provide a single unit that can be mounted to a support, such as the frame of a work truck. For example, in the illustrated configuration, the air compressor 16 is configured to be attached to the frame of the work truck with appropriate fasteners and / or welding, and the other components are supported by the air compressor and do not need to be individually attached to the frame for support. This single configuration facilitates easier installation and / or removal, for example, for maintenance, and minimizes the need to modify the truck frame. However, in other configurations, the components may be supported and / or connected to one another directly or indirectly in different arrangements, and the power system 10 is not limited to the arrangement, number, or type of components shown in the figures.

[0032] A power system 10 according to some non-limiting embodiments of the present invention can capture energy from a single PTO drive on a work truck and use it to power a variety of different types of machinery by integrating various forms of rotational power. This innovative approach addresses many of the design optimization aspects discussed above, which typically result in cost savings, weight optimization, reduced maintenance complexity due to the elimination of multiple prime movers, and / or the creation of new space on a vehicle (e.g., a specialized work truck). This integration, in some configurations, can improve the power efficiency and increase the cargo capacity of a work truck compared to work trucks traditionally configured to provide the same various power sources. Furthermore, the environmental sustainability and economic benefits of this combination of rotational power sources are enhanced by reduced fuel consumption during work truck operation.

[0033] Work trucks equipped with the power system 10 disclosed herein for jobsite maintenance, infrastructure, and emergency response purposes (and others) can advantageously provide many forms of power at a jobsite. For example, when configured as a PTO shaft-driven underdeck power system 10 as shown in FIG. 4, the power system 10 advantageously provides a streamlined system that can replace up to six separate pieces of equipment on a work truck. This configuration can provide additional bed space for the work truck to which it is attached, increasing its maneuverability, reducing maintenance needs, freeing up hitches, and / or reducing overall weight, which are highly desirable at many jobsites. Such a configuration can be seamlessly integrated under the vehicle's chassis, thereby creating cargo space and increasing overall efficiency.

[0034] FIG. 5 illustrates a vehicle 40, such as a work truck, having a power system 10 as described herein. The vehicle 40 may include a frame 42 or other body structure supported by a plurality of wheels 44. The vehicle has an engine 46 coupled to a transmission 22, which drives the PTO 26. In one exemplary embodiment, the air compressor of the power system 10 is mounted directly to the frame 42, which supports the power transfer linkage, hydraulic pump, and generator, eliminating the need for individual frame mounting for support of these components. This single unit configuration allows for easier installation and / or removal, for example, for maintenance, and minimizes the need for modifications to the truck frame.

[0035] It should be apparent that the present disclosure is an example and that various modifications may be made by adding, modifying, or eliminating details without departing from the fair scope of the teachings contained herein. Accordingly, the invention is not limited to the particular details of this disclosure except to the extent that the following claims are necessarily so limited. [Explanation of symbols]
