[0033] In the following detailed description, reference is made to the accompanying drawings. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It should be readily understood that the aspects of the present disclosure generally described herein and shown in the accompanying drawings may be arranged, substituted, combined, and designed in a variety of different configurations, all of which are expressly contemplated and constitute a part of the present disclosure. DETAILED DESCRIPTION

[0034] The following is a more detailed description of various concepts and implementations of systems and methods related to hybrid electric powertrain systems without the use of expensive and hard-to-find equipment. Before turning to the drawings that show certain exemplary embodiments in detail, it should be understood that the disclosure is not limited to the details or methods set forth in the specification or shown in the drawings. It should also be understood that the terminology used herein is for descriptive purposes only and should not be considered limiting.

[0035] According to various example embodiments, the systems and methods disclosed herein relate to a chassis assembly. The chassis assembly may be configured to support a generator set ("genset") and to accommodate or define a fuel tank configured to store fuel for powering the generator set. The chassis assembly includes a pair of side rails, and the fuel tank is disposed between the side rails. The chassis assembly includes at least one cross member extending between the side rails to provide additional support for the generator set. At least one cross member is at least partially disposed in the fuel tank. Therefore, the cross member does not add additional height to the chassis assembly. The absence of additional height can maintain a lower center of gravity of the generator set and allow the fuel tank to occupy more space between the side rails. Therefore, the storage capacity of the fuel tank can be increased without increasing the footprint of the chassis assembly.

[0036] At least one cross member includes a top plate that forms part of the top surface of the fuel tank or is coupled to the top surface of the fuel tank. For example, at least one cross member can be completely immersed in the fuel tank so that the top plate abuts against the inner surface of the top surface of the fuel tank. Alternatively, at least one cross member can be partially immersed so that the top plate forms part of the top surface and the side walls of the cross member are arranged in the fuel tank. In the case where the top plate forms part of the top surface, the top surface can include the top plate and other panels that can be sealably coupled together (e.g., welded) to reduce fuel leakage. In particular, fuel can be prevented from leaving the fuel tank via the top surface.

[0037] The side wall of the cross member may include at least one opening to allow fluid to flow therethrough. For example, the top plate and the side wall of the cross member may form a channel in the fuel tank. When fuel fills the fuel tank, air pockets may form in the channel. The opening allows air in the channel to escape the channel to allow the fuel to fill the channel. The opening may be disposed proximate to the top plate of the cross member to minimize the amount of air trapped in the channel and maximize storage space for the fuel. Thus, the formation of air pockets may be reduced.

[0038] The top plate of at least one cross member may include at least one recess. The recess may be configured to couple an external component (e.g., an anti-vibration mount) to the at least one cross member. The recess may be sealably coupled (e.g., welded) to the top plate to prevent fuel from exiting the fuel tank via an interface between the top plate and the recess. The recess may extend into the channel of the cross member and into the fuel tank.

[0039] refer to Figure 1 and Figure 2, perspective and top views of a chassis assembly 100 for a generator set (“genset”) are shown according to an example embodiment. The chassis assembly 100 is a structural support system configured to support the generator set. For example, the generator set can be disposed on the chassis assembly 100. The chassis assembly 100 includes a frame 105. The frame 105 includes at least one side member, shown as a side rail 110. The side rail 110 can extend the length of the chassis assembly 100. The frame 105 can include at least one end member 115. The end member 115 can extend the width of the chassis assembly 100.

[0040] The frame 105 may include a first side rail 110 and a second side rail 110. An end member 115 may extend between the first side rail 110 and the second side rail 110. For example, the first side rail 110 may be located away from the second side rail 110. For example, the first side rail 110 may be parallel to and spaced apart from the second side rail 110. A first end of the end member 115 may be coupled to the first side rail 110, and a second end of the end member 115 may be coupled to the second side rail 110. The end member 115 may be coupled to the side rail 110 at an end of the side rail 110. The frame 105 may include a plurality of end members 115. For example, the frame 105 may include a first or front end member 115 and a second or rear end member 115. The front end member 115 and the rear end member 115 may extend between the first side rail 110 and the second side rail 110. The front end member 115 may be coupled to the front end of the side rail 110 , and the rear end member 115 may be coupled to the rear end of the side rail 110 .

[0041] The frame 105 can define a cavity 120. For example, two end members 115 coupled to and disposed between the two side rails 110 can define the cavity 120. As described in more detail herein, at least a portion of the cavity 120 can be used as a fuel tank 125. The fuel tank 125 is disposed between the first side rail 110 and the second side rail 110. The fuel tank 125 can store fuel to power a generator set supported by the chassis assembly 100. The fuel tank 125 can extend along at least a portion of the frame 105. The side rails 110 can be sides of the fuel tank 125.

[0042] The chassis assembly 100 includes at least one structural support member, shown as a cross member 130.

The cross member 130 is at least partially disposed in the fuel tank 125 of the chassis assembly 100. The cross member 130 can extend between the side rails 110 and be coupled to the side rails 110. For example, a first end of the cross member 130 can be coupled to the first side rail 110, and a second end of the cross member 130 can be coupled to the second side rail 110. In some embodiments, the ends of the cross member 130 are welded to the side rails 110. The chassis assembly 100 can include a plurality of cross members 130. For example, the chassis assembly 100 can include two, three, four, or more cross members 130. In some embodiments, different cross members 130 can support different components of the generator set. For example, first cross member 130 may be configured to support a first component of a generator set (eg, an engine), and second cross member 130 may be configured to support a second component of the generator set (eg, a generator or alternator).

[0043] The chassis assembly 100 includes a top surface 135. The top surface 135 can be configured to support a generator set. For example, the generator set can be disposed on the top surface 135 of the chassis assembly 100. The top surface 135 can be the top of the fuel tank 125. The top surface 135 can extend between the first side rail 110 and the second side rail 110. The top surface 135 can include at least one panel 140. The panel 140 can be a flat and thin piece of material (e.g., a metal plate) to generate at least a portion of the top surface 135. The top surface 135 can include a plurality of panels 140. The panels 140 can be coupled together to form the top surface 135. For example, the panels 140 can be welded together.

[0044] In some embodiments, the top surface 135 may also include a portion of the cross member 130. For example, as described in more detail herein, a top portion of the cross member 130 may form a portion of the top surface 135. In such embodiments, the panel 140 may be coupled to the top portion of the cross member 130 to form the top surface 135. For example, the panel 140 may be welded to the cross member 130. In some embodiments, the top surface 135 may include a plurality of panels 140 and a plurality of portions of the cross members 130. At least one panel 140 may be disposed between each cross member 130. The panel 140 and the cross member 130 may be sealably coupled together (e.g., welded together) to form the top surface 135.

[0045] The chassis assembly 100 may include at least one other structural support member, shown as an outer cross member 145. The outer cross member 145 may be disposed outside of the fuel tank 125. The outer cross member 145 may be the same as or different from the cross member 130. For example, the size, shape, number and type of openings, or other features of the outer cross member 145 may be the same as or different from the cross member 130.

[0046] refer to Figure 3 and Figure 4 , a bottom perspective view and a top view of a cross member 130 according to an example embodiment are shown. The cross member 130 has a top portion, shown as a top plate 305. The cross member 130 has at least one side wall 310 extending from the top plate 305. In some embodiments, the cross member 130 can be curved. For example, the cross member 130 can have a C-shape. For example, the cross member 130 can have a first side wall 310 extending from a first edge of the top plate 305 and a second side wall 310 extending from a second edge of the top plate 305. The side wall 310 can be coupled to the top plate 305 or be integral (e.g., integral) with the top plate 305. For example, the side wall 310 and the top plate 305 can be formed by a single component, wherein the side wall 310 is bent to extend in the same direction from the top plate 305 to form a C-shape.

[0047] The side wall 310 may have a first edge (shown as a top edge 315) and a second edge (shown as a bottom edge 320). The top edge 315 may be an edge of the side wall 310 that is coupled to or integral with (e.g., transitions into) the top plate 305. The bottom edge 320 may be an edge of the side wall 310 that is opposite the top edge 315 and spaced from the top plate 305. The cross member 130 may include a transition portion 325. The transition portion 325 may be disposed between the top plate 305 and the side wall 310. For example, the transition portion 325 may be a curved portion that transitions the top plate 305 into the side wall 310. The transition portion 325 may be a joint or a coupling mechanism that couples the side wall 310 to the top plate 305.

[0048] In some embodiments, all cross members 130 may have the same configuration (e.g., C-shaped). In some embodiments, cross members 130 may have different configurations or shapes. For example, a first cross member 130 may have a first shape, and a second cross member 130 may have a second shape. For example, a first cross member 130 may have a C-shape. A second cross member 130 may have a top hat shape (e.g., flanges extending away from each other from the free edges of the two side walls 310). The shape of the cross members 130 may be based on the amount of load that the cross members 130 are to support. For example, a cross member 130 having a first shape may be configured to support a greater load than a cross member 130 having a second shape.

[0049] The cross member 130 can define a channel 330. The channel 330 can be defined by the top plate 305, the first side wall 310, and the second side wall 310. The channel 330 can extend the length of the cross member 130.

[0050] The cross member 130 includes at least one opening 335. The opening 335 can extend through the cross member 130 to connect the channel 330 with the ambient fluid outside the cross member 130. The opening 335 can be a vent for a fluid (e.g., air) to leave the channel 330. For example, the opening 335 can be configured for a fluid to flow through. The opening 335 can be of any shape or size. For example, the opening 335 can be circular or square, or can have an elongated shape, etc. The side wall 310 of the cross member 130 defines at least one opening 335. The opening 335 can extend through the side wall 310. The opening 335 can be positioned closer to the top edge 315 of the side wall 310 than to the bottom edge 320. In some embodiments, the opening 335 is positioned as close to the top plate 305 as possible. For example, the opening 335 can be positioned at the top edge 315 of the side wall 310. The opening 335 can be located in the transition portion 325 of the cross member 130.

[0051] The cross member 130 can include a plurality of openings 335. For example, the plurality of openings 335 can be disposed along the length of the cross member 130. The plurality of openings 335 can be disposed along the side wall 310 of the cross member 130. A first opening or a first plurality of openings 335 can be disposed on the first side wall 310, and a second opening 335 or a second plurality of openings 335 can be disposed on the second side wall 310. The openings 335 can be disposed adjacent to the top plate 305 of the cross member 130.

[0052] The cross member 130 may include at least one recess 340. The recess 340 may be configured to receive a protrusion of an external component. For example, the recess 340 may be a protrusion extending from the top plate 305 of the cross member 130 into the channel 330. The recess 340 may be configured to receive a protrusion from an external component. For example, the recess 340 may define a cavity configured to receive a protrusion. The depth of the recess 340 may be based on the length of the protrusion to be set in the recess 340. The recess 340 may be a closed recess 340. For example, the cavity defined by the recess 340 may not be exposed to the channel 330 to prevent any fluid or material in the channel from entering the recess 340. The recess 340 may be coupled to the top plate 305 of the cross member 130. For example, the recess 340 may be welded or bonded to the top plate 305, or otherwise fixed to the top plate 305. The recess 340 may be coupled to the top plate 305 such that fluid or material from within the channel 330 cannot exit the channel 330 via an interface between the recess 340 and the top plate 305 .

[0053] The cross member 130 may have a plurality of pockets 340. The number of pockets 340 may be based on the number of external components to be coupled to or disposed on the cross member 130. The pockets 340 may be disposed along the top plate 305 of the cross member 130.

[0054] Reference now Figure 5 , shows a front view of the cross member 130 according to an example embodiment. The pocket 340 may extend into the channel 330 of the cross member 130. The pocket 340 may extend perpendicular to the top plate 305. In some embodiments, the chassis assembly 100 may include an external component 505. The external component 505 may be, for example, an anti-vibration mount. The external component 505 may include at least one protrusion 510 configured to be disposed in the pocket 340. The pocket 340 may be configured to receive the protrusion 510 of the external component 505. The size and shape of the pocket 340 may be based on the size and shape of the protrusion 510 to be received. The pocket 340 may be configured to couple the external component 505 with the cross member 130. For example, the pocket 340 may include a coupling mechanism 515. The coupling mechanism 515 may be configured to interface with the protrusion 510 of the external component 505. In some embodiments, the coupling mechanism 515 may be a thread configured to interface with a corresponding thread of the protrusion 510. The coupling mechanism 515 may be any type of mechanism configured to interface with the protrusion 510 of the outer component 505 and couple the outer component 505 with the cross member 130 .

[0055] refer to Figure 6 , shows a cross-sectional view of a portion of a chassis assembly 100 according to an example embodiment, as taken along Figure 1 1. The fuel tank 125 may be formed within the cavity 120 of the chassis assembly 100. For example, the fuel tank 125 has a top surface 135. The top surface 135 of the fuel tank 125 is the top surface 135 of the chassis assembly 100. The side rails 110 of the chassis assembly 100 may be the sides of the fuel tank 125. The chassis assembly 100 may have additional structural members or tank walls 605 that define the shape of the fuel tank 125 within the cavity 120.

[0056] The chassis assembly 100 includes at least one cross member 130 at least partially disposed in the fuel tank 125. Disposing the cross member 130 in the fuel tank 125 can increase the capacity of the fuel tank 125 while reducing the overall height. Therefore, the center of gravity of the generator set disposed on the chassis assembly 100 can be reduced relative to the center of gravity when the cross member 130 is in a raised position. For example, the side wall 310 of the cross member 130 can be disposed in the fuel tank 125. The top plate 305 of the cross member 130 is disposed flush with or below the top surface 135. For example, in some embodiments, the top plate 305 of the cross member 130 can form a portion of the top surface 135 of the fuel tank 125. For example, the panel 140 of the top surface 135 can be sealably coupled with the top plate 305 of the cross member 130 to produce the top surface 135. In some embodiments, the top surface 135 can include only the panel 140, wherein the top plate 305 is disposed below the top surface 135 in the fuel tank 125. Top plate 305 may still be coupled to panel 140 , but to an inner surface of panel 140 .

[0057] According to an exemplary embodiment, the fuel tank 125 includes a top surface 135. The top surface 135 includes the panel 140 and a top plate 305 of the cross member 130. The top plate 305 is coupled to the panel 140. The cross member 130 includes the top plate 305. The cross member 130 includes a first side wall 310 extending from a first edge of the top plate 305 and a second side wall 310 extending from a second edge of the top plate 305.
