[0016] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, the traditional generator 5 and the 48V motor 9 are both fixed to the cylinder head 2 and the generator bracket 4 by bolts, and the front end is driven by the engine through a belt pulley. In actual use, due to the different structures of the traditional generator 5 and the 48V motor 9, the motor installation points are inconsistent, which leads to structural changes in the cylinder head 2, the synchronous chain cover 3, the generator bracket 4 and other parts that fix the motor, and new parts are generated. In order to overcome this design difficulty, the technical solution of the utility model is that the traditional generator 5 and the 48V motor 9 use the same installation points and structural dimensions, so that the traditional and hybrid power engines can match the same cylinder body 1, cylinder head 2, synchronous chain cover 3, generator bracket 4 and other parts, reduce the design cost, and facilitate adaptation to different engines.

[0018] Specifically, the utility model provides a generator arm that takes into account the requirements of both hybrid and traditional power trains, including an engine cylinder block 1, a cylinder head 2, and a generator bracket 4; the cylinder head 2 and the synchronous chain cover 3 are respectively mounted on the engine cylinder block 1, and the generator bracket 4 is fixed to the engine cylinder block 1 by bolts. The generator bracket 4 is used to fix the traditional generator 5 or the 48V motor 9, and the motor arm 12 of the traditional generator 5 and the 48V motor 9 adopts the same mounting point and size. The traditional and hybrid power engines can use the same cylinder block 1, cylinder head 2, synchronous chain cover 3, generator bracket 4 and other parts. Reduce the changes in other engine parts caused by different motor arm structures and reduce design costs.

[0019] The upper hanging points of the motor arms 12 of the conventional generator 5 and the 48V motor 9 are fixed on the cylinder head 2 and the synchronous chain cover 3 , and the lower hanging points of the motor arms 12 are fixed on the generator bracket 4 .

[0020] like Figure 3 , Figure 4 As shown, they are schematic diagrams of the motor arm 12 of the conventional generator 5 and the 48V motor 9;

[0021] The relevant length dimensions L1, L2 and L3 of the motor arm 12 of the conventional generator 5 are the same as the length dimensions L1, L2 and L3 of the motor arm 12 of the 48V motor 9;

[0022] The relevant thickness dimensions D1, D2, D3, D4, D5 and D6 of the motor support arm 12 of the conventional generator 5 are the same as the thickness dimensions D1, D2, D3, D4, D5 and D6 of the motor support arm 12 of the 48V motor 9;

[0023] The relevant hole dimensions d1, d2, d3 and d4 of the motor support arm 12 of the conventional generator 5 are the same as the hole dimensions d1, d2, d3 and d4 of the motor support arm 12 of the 48V motor 9;

[0024] Among them: L1 is the upper hanging point spacing 37.6mm, L2 is the lower hanging point spacing, L3 is the distance between the lower hanging point of the rear end cover and the pulley center 106.5mm;

[0025] D1 is the thickness of the bushing at the upper hanging point of the rear end cover, 17.5mm; D2 is the thickness of the upper hanging point of the front end cover, 13.5mm; D3 is the thickness of the bushing at the lower hanging point of the rear end cover, 17.5mm; D4 is the thickness of the lower hanging point of the front end cover, 12mm; D5 is the thickness of the upper hanging point of the rear end cover, 11mm; D6 is the thickness of the lower hanging point of the rear end cover, 11mm;

[0026] d1 is the threaded hole M10✕1.25-6H for the hanging point on the rear end cover, d2 is the through hole with a diameter of 11.2mm for the hanging point on the front end cover, d3 is the threaded hole M10✕1.25-6H for the hanging point under the rear end cover, and d4 is the through hole with a diameter of 11.2mm for the hanging point under the front end cover.

[0027] The same-layer transmission wheel system used by the traditional generator 5 includes: a traditional generator 5 driving wheel, an automatic tensioner 6, a crankshaft pulley 7, and a compressor 8 connected by a belt drive; the automatic tensioner 6 and the crankshaft pulley 7 are installed on the synchronous chain cover 3, and the compressor 8 is installed on the engine cylinder block 1.

[0028] The same-layer transmission wheel system used by the 48V motor 9 includes: a 48V motor 9 driving wheel, a crankshaft pulley 7, an Ω tensioning wheel 10, and an idler wheel 11 connected by belt drive; the crankshaft pulley 7, the Ω tensioning wheel 10 and the idler wheel 11 are all installed on the synchronous chain cover 3.

[0029] After the engine block 1 and the cylinder head 2 are fixed in position, the generator bracket 4 is fixed to the engine block 1 by bolts, the conventional generator 5 and the 48V motor 9 are fixed by bolts, the upper hanging point of the motor support arm 12 is fixed to the cylinder head 2 and the synchronous chain cover 3, and the lower hanging point of the motor support arm 12 is fixed to the generator bracket 4.

[0030] In order to meet the same space layout requirements and adapt to the installation of both traditional and hybrid engines, the traditional generator 5 and the 48V motor 9 use the same support arm installation dimensions, keeping the wall thickness of the front and rear end cover support arms of the motor, the size of the rear end cover bushing, the relative position of the upper and lower hanging points of the support arms and other fixed dimensions the same, so that the traditional generator 5 and the 48V motor 9 use the same installation point. Under the premise that the engine components except the gear train are completely borrowed, the design is combined with the two gear trains and other engine components of traditional and hybrid power.

[0031] The front and rear end covers of the generator are the main parts of the generator assembly. The support arm structure of the front and rear end covers directly affects the installation position and mechanical strength of the generator. Under the premise of meeting the mechanical strength of the front and rear end covers of the generator, the traditional generator 5 and the 48V motor 9 use the same support arm installation size, which greatly reduces the different structures of the traditional generator 5 and the 48V motor 9, resulting in inconsistent motor installation points, and then causing structural changes in the components that fix the motor, such as the cylinder head 2, the synchronous chain cover 3, and the generator bracket 4, reducing the probability of matching different engines with components in different states and reducing development and design costs.
