[0002] In related technologies, the engine in a vehicle is usually connected to various accessories through a front-end wheel system. These accessories include, but are not limited to, air conditioning compressors and generators, to meet the vehicle's heating and cooling needs and the power supply needs of the vehicle's electrical system. However, the increase in the number of accessories results in defects in the vehicle's power system, such as low layout tolerance, limited size and power of accessories, low integration, and inconvenient maintenance. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a power system that has the advantages of minimal restrictions on the size and power of accessories and high tolerance for misalignment in the vehicle layout.

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is combined with Figures 1-6 A power system according to an embodiment of the present utility model is described.

[0027] The power system of this embodiment includes an engine 1, a front-end gear train 2, and accessories. The engine 1 includes a body 11 and a crankshaft 12. The crankshaft 12 includes a front end protruding from a first side of the body 11 and a rear end protruding from a second side of the body 11. The rear end of the crankshaft 12 is configured as an output end. The front-end gear train 2 is located on the first side of the body 11 and includes a belt 21, a drive pulley 22, a load pulley 23, and an auxiliary pulley. The drive pulley 22 is connected to the front end of the crankshaft 12. The drive pulley 22 is connected to the load pulley 23 and the auxiliary pulley via the belt 21. The accessories are located on the side of the front-end gear train 2 opposite to the body 11, and the input end of the accessories is connected to the load pulley 23.

[0028] According to the power system of this utility model embodiment, the front end of the crankshaft 12 of the engine 1 is connected to the drive wheel 22 of the front wheel train 2, and the input end of the accessory is connected to the load wheel 23 of the front wheel train 2. That is, when the engine 1 is working, the accessory is driven to work through the front wheel train 2 to realize the nearby function. In particular, by setting the accessory on the side of the front wheel train 2 away from the engine body 11, that is, the accessory and the engine body 11 are arranged along the length direction of the engine 1, the size of the accessory is not affected by the size and shape of the engine body 11, nor by the space size of the vehicle in the width direction of the engine 1. The size and power of the accessory are more flexible and less restricted, and the space in the length direction of the vehicle is more abundant. The error tolerance of the power system layout on the vehicle is higher.

[0029] It should be noted that the length of the engine block 11 is aligned with the axis of the crankshaft 12, and the width of the engine block 11 is orthogonal to the length and height directions. Because the width direction houses the intake system, exhaust system, and transmission of the engine block 11, the space in the width direction of the entire vehicle is extremely limited. Taking the generator 3 as an example, compared to placing the generator 3 on the opposite side of the engine block 11 along its width direction, which would require redesigning the crankshaft 12 housing and cylinder block, and limiting the maximum power to less than 1kW due to space constraints, this embodiment places the generator 3 on the opposite side of the engine block 11 along its length direction. This eliminates the need to modify the structure and dimensions of the engine block 11, and increases the length of the power system. This direction offers more flexibility in the overall vehicle layout and has a higher tolerance for error.

[0030] In some embodiments, the number of accessories is at least two, with each load wheel 23 corresponding to one accessory, and the power system also includes a bracket 5, on which all accessories are mounted.

[0031] Compared to related technologies where at least two accessories are located on opposite sides of the body 11 along the width direction of the engine 1, requiring at least two supports 5 for support, in this embodiment, at least two accessories are located on the same side of the body 11 along the length direction, making it easier to install all accessories on the same support 5 simultaneously. This results in fewer total components in the power system, a simpler structure, and easier assembly and disassembly of the power system.

[0032] For example, all accessories are detachably mounted to the same side of the bracket 5 by bolts. The arrangement direction of all accessories can be consistent with or intersect with the width direction of the body 11. Alternatively, all accessories can be arranged circumferentially around the drive wheel 22.

[0033] In some embodiments, there are two load wheels 23, and the two load wheels 23 and the drive wheel 22 are arranged in a triangular pattern.

[0034] By setting the two load wheels 23 and the drive wheel 22 in a triangular distribution, the two accessories corresponding to the two load wheels 23 can be spaced further apart without interfering with each other. The maximum size of the two accessories in the arrangement direction is smaller, the space occupied is smaller, the structure of the power system is more compact, and the installation fault tolerance on the whole vehicle is lower.

[0035] For example, such as Figure 4 and Figure 6 As shown, the two load wheels 23 are arranged at intervals along the width direction of the body 11, the central axis of the drive wheel 22 is located below the central axis of any load wheel 23, and the upper edge of the drive wheel 22 is higher than the lower edge of at least one load wheel 23.

[0036] In some embodiments, the center of the auxiliary wheel is located within the triangular area enclosed by the two load wheels 23 and the drive wheel 22.

[0037] This effectively prevents the belt 21 from extending beyond the triangular area formed by the two load pulleys 23 and the drive pulley 22, thus avoiding increased risk of damage from external interference and improving the reliability and service life of the front-end pulley system 2. It also makes the power system more compact, occupies less space, and has a lower tolerance for installation errors on the vehicle.

[0038] For example, such as Figure 4 and Figure 6 As shown, on the projection plane orthogonal to the axis of the driving wheel 22, the projection of the central axis of the auxiliary wheel is located within the triangular area enclosed by the projections of the central axes of the two load wheels 23 and the projection of the central axis of the driving wheel 22.

[0039] In some embodiments, such as Figures 1-6 As shown, there are two accessories, namely a generator 3 and an air conditioning compressor 4.

[0040] At this point, the size and power of the generator 3 and the air conditioning compressor 4 are less restricted, and the engine 1 and the air conditioning compressor 4 can be selected more flexibly according to the usage requirements to better meet the vehicle's power supply and air conditioning heating and cooling needs.

[0041] In some embodiments, the number of load wheels 23 is three, and the three load wheels 23 are arranged in a triangular distribution. That is, the number of accessories is three and they are arranged in a triangular distribution.

[0042] In other words, when there are three accessories, the triangularly distributed accessories have a more compact structure, occupy less space, and have a higher fault tolerance rate in normal installation.

[0043] For example, in addition to the generator 3 and the air conditioning compressor 4, the accessories can also include a water pump, a cooling fan, a hydraulic power steering pump, a power steering pump, and a high-pressure oil pump, so that the power system has more functions and can meet the more complex usage needs of the vehicle. Furthermore, when there are three load wheels 23, it is preferable to position the brake wheel within the triangular area enclosed by the three load wheels 23, or between two adjacent load wheels 23.

[0044] It should be noted that the number of attachments can also be four, five or more. In this case, the number of load wheels 23 of the front wheel system 2 is also four, five or more.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the bracket 5 is located on the side of the accessory facing the body 11, that is, the bracket 5 is located between the accessory and the body 11. At this time, the body 11 is mounted on the bracket 5.

[0046] In other words, both the accessories and the main body 11 are mounted on the bracket 5. This results in higher relative positional accuracy between the engine 1 and each accessory, leading to higher and more reliable driving accuracy of the engine 1 for each accessory. Furthermore, it reduces the number of components in the power system, making the power system more compact and highly integrated. For example, the body 11 is detachably mounted to the bracket 5 by bolts. When the power system is installed on the vehicle body, the body 11 can be directly connected to the vehicle body at the same time as the bracket 5 is connected to the vehicle body, so as to further improve the installation strength of the power system on the vehicle body.

[0047] In some embodiments, the auxiliary wheel includes an idler wheel 24, which is rotatably mounted on the bracket 5.

[0048] By setting the idler pulley 24, the direction of the belt 21 can be changed, and the wrap angle between the drive pulley 22 and the load pulley 23 can be increased, so that the transmission of the front-end pulley system 2 is smoother. By also rotating the idler pulley 24 onto the bracket 5, no other frame is needed, further reducing the number of parts in the power system, and improving the assembly efficiency and integration of the power system.

[0049] It should be noted that the auxiliary pulley may also include a tensioner to adjust the tension of the belt 21, ensuring sufficient friction between the belt 21 and the drive pulley 22 and the load pulley 23 to prevent slippage.

[0050] In some embodiments, the power system also includes a protective cover, which is connected to the bracket 5 and covers all accessories.

[0051] The protective cover encloses all accessories to effectively prevent external dust and impurities from adhering to them and affecting their service life. Furthermore, since all accessories are located on the same side of the front wheel system 2 away from the main body 11, only one protective cover is needed to cover all accessories, resulting in low cost for accessory protection.

[0052] It should be noted that the protective cover can not only cover the accessories but also the front wheel system 2, thereby effectively protecting the belt 21, drive pulley 22, load pulley 23, and auxiliary pulley, and improving the service life and reliability of the front wheel system 2. Furthermore, in addition to being connected to the bracket 5, the protective cover can also be connected to the main body or vehicle body, as long as it can protect the accessories and / or the front wheel system 2.
