[0027] Please refer to Figure 1 and Figure 2 As shown, a dual-generator wheel system for a diesel engine in a motorhome includes:

[0028] The first gear train includes a crankshaft pulley 2, a fan pulley 3, a water pump pulley 4, an air conditioning pulley 5, and a first generator 6, which are connected by a first multi-ribbed belt 1.

[0029] The second gear train includes a water pump pulley 4 and a second generator 8, which are driven by a second multi-wedge belt 7.

[0030] The water pump pulley 4 is a double-layer pulley, with the first multi-wedge belt 1 and the second multi-wedge belt 7 respectively embedded in it.

[0031] Furthermore, the crankshaft pulley 2, the fan pulley 3, and the first generator 6 are located on one side of the water pump pulley 4, while the air conditioning pulley 5 and the second generator 8 are located on the other side of the water pump pulley 4.

[0032] Furthermore, the first generator 6 is connected to the engine block via the first bracket 9.

[0033] Meanwhile, a first tensioning pulley 10 is detached and installed on the side wall of the engine cylinder block. The first tensioning pulley 10 is connected to the first multi-wedge belt 1 for transmission. The first tensioning pulley 10 is used to tension the first multi-wedge belt 1.

[0034] Furthermore, the second generator 8 is connected to the air conditioner via the second bracket 11. The second bracket 11 includes a horizontal plate 12 and a vertical plate 13. The second generator 8 is detachably connected to the vertical plate 13. A second tensioning wheel 14 is detachably installed on the side wall of the vertical plate 13. The second tensioning wheel 14 is connected to the second multi-ribbed belt 7 for transmission. The second tensioning wheel 14 is used to tension the second multi-ribbed belt 7.

[0035] More specifically, the top surface of the horizontal plate 12 is provided with a plurality of positioning cylinders 15, the positioning cylinders 15 being vertically penetrating and having internal threads 16 on their inner walls. The top surface of the horizontal plate 12 is provided with a reinforcing outer plate 17 surrounding the positioning cylinders 15. The reinforcing outer plate 17 is provided with a plurality of reinforcing ribs within its surrounding area. The two ends of the reinforcing ribs are connected to the inner walls of the reinforcing outer plate 17 and the outer walls of the positioning cylinders 15, or the two ends of the reinforcing ribs are connected to the outer walls of two adjacent positioning cylinders 15.

[0036] Thus, for this application, the power generation of the diesel engine is increased, the cost of adding a generator by the modification plant is reduced from the source, the quality and after-sales problems caused by the high cost of the addition and the uneven quality of the modification are reduced, the overall engine layout is more compact, the structure is simple, the assembly is convenient, the reliability is high, and the cost of using it in the whole vehicle is low.

[0037] Using the water pump pulley 4 as a double-layer pulley can effectively shorten the length of the multi-ribbed belt and reduce the risk of tooth skipping. It can also avoid interference between the second multi-ribbed belt 7 and the engine sprocket cover. Furthermore, other pulleys such as the fan pulley 3 use single-layer pulleys, so that the overall cantilever length remains unchanged after the fan is assembled, resulting in higher fan reliability and a more compact overall engine length.

[0038] Furthermore, even if the second multi-wedge belt 7 breaks during actual use, it will not affect the normal operation of the first generator 6, air conditioning, and water pump and fan in the engine cooling system, thus effectively ensuring the safety of the entire vehicle through the layout.

[0039] Meanwhile, the integrated design of the second bracket 11 reduces the number of parts and reduces the wear and skipping of the second multi-wedge belt 7 caused by the cumulative error of multiple parts assembly. At the same time, the design of the positioning cylinder 15, reinforcing ribs and reinforcing outer plate 17 improves the overall strength and durability.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
