[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1 to 3 As shown, the split-mount diesel engine pulley cover of this utility model includes a cover body 1, a fan pulley cover 2, a crankshaft pulley cover 3, and a support assembly 4. The fan pulley cover 2 is detachably mounted on the upper part of the cover body 1, the crankshaft pulley cover 3 is detachably mounted on the lower part of the cover body 1, and the support assembly 4 is located inside the cover body 1 for supporting and connecting the cover body 1.

[0023] The support assembly 4 includes a first connecting bolt 41, a support frame 42, and a second connecting bolt 45. The support frame 42 is connected to the engine 100 via the first connecting bolt 41, and the support frame 42 is connected to the housing body 1 via the second connecting bolt 45.

[0024] Furthermore, in the split-mount diesel engine pulley cover of this utility model, the cover body 1 is an integral stamped semi-enclosed structure. A fan pulley protection zone 11 is provided at one end of the upper inner side of the cover body 1, a generator pulley protection zone 12 is provided at the other end of the upper inner side of the cover body 1, a compressor pulley protection zone 13 is provided at one end of the lower inner side of the cover body 1, and an engine pulley protection zone 14 is provided at the other end of the lower inner side of the cover body 1. The fan pulley protection zone 11, the generator pulley protection zone 12, the compressor pulley protection zone 13, and the engine pulley protection zone 14 are all annular protrusions, thereby effectively ensuring that the protruding parts of the fan pulley 200, the generator pulley 300, the compressor pulley 400, and the engine pulley 500 are all within the annulus, effectively improving the protection of the pulleys.

[0025] Furthermore, in the split-mount diesel engine pulley cover of this utility model, ventilation holes 15 are evenly provided on the main body 1 of the cover between the fan pulley protection zone 11 and the engine pulley protection zone 14 and between the compressor pulley protection zone 13 and the engine pulley protection zone 14, thereby effectively ensuring the heat dissipation of the engine 100.

[0026] Furthermore, in the split-mount diesel engine pulley cover of this utility model, the cover body 1 is provided with a drive connection hole 16 through the fan pulley protection zone 11 and the engine pulley protection zone 14. The cover body 1 is provided with a first threaded hole 17 around the drive connection hole 16. The drive connection hole 16 is respectively matched with the fan pulley cover 2 and the crankshaft pulley cover 3. The fan pulley cover 2 is threadedly engaged with the first threaded hole 17 corresponding to the fan pulley protection zone 11 by bolts. The crankshaft pulley cover 3 is threadedly engaged with the first threaded hole 17 corresponding to the engine pulley protection zone 14 by bolts. Thus, when connecting the fan pulley and the engine pulley to other drive devices such as fans and additional pulleys, installation can be carried out by removing the fan pulley cover 2 and the crankshaft pulley cover 3 without removing the cover body 1.

[0027] Furthermore, in the split-mount diesel engine pulley cover of this utility model, mounting holes 18 are provided at the upper, middle and lower parts of the cover body 1, a through hole 43 is provided at one end of the bracket, and a second threaded hole 44 is provided at the other end of the bracket. The first connecting bolt 41 passes through the through hole 43 and engages with the engine 100 thread, and the second connecting bolt 45 passes through the mounting hole 18 and engages with the second threaded hole 44 thread. When installing the cover body 1, the bracket can be installed first, so that the bracket is hidden inside the cover body, which not only facilitates the installation of the cover body 1, but also reduces the area occupied by the cover.

[0028] Furthermore, in the split-mount diesel engine pulley cover of this utility model, the height of the bracket after installation is 3mm to 10mm higher than the highest point of the engine 100, thereby effectively avoiding friction between the cover body 1 and the engine 100 during operation.

[0029] Specifically, when installing the pulley cover, the support assembly 4 is first installed on the engine 100, and then the cover body 1 is installed through the support assembly 4. After the cover body 1 is installed, when connecting the fan pulley and engine pulley to other drive devices such as fans and additional pulleys, it is installed through the drive connection hole 16. The drive connection hole 16, which is not connected to other drive devices such as fans and additional pulleys, is protected by the fan pulley cover 2 or the crankshaft pulley cover 3, so that the protection scenario is more flexible.

[0030] In summary, compared with the prior art, the split-mount diesel engine pulley cover of this utility model has the following advantages and beneficial effects: the overall structure of this utility model is simple, thin and easy to install, and has ventilation holes that do not affect the engine cooling airflow, effectively avoiding damage to the pulley and belt from foreign objects during operation. The use of fan pulley cover and crankshaft pulley cover makes the protection scenario more flexible, and can protect the pulley end while connecting the crankshaft pulley and fan pulley to other drive components.
