[0018] The embodiment of the present application provides a diesel engine accessory bracket, which effectively solves the problem that the oil pump of the existing diesel engine accessory bracket is installed independently and is mainly driven by gear transmission. On the one hand, there is wear at the gear meshing point. If the wear is serious, it will cause the transmission ratio to change, affecting the engine fuel supply. The diesel engine accessory bracket directly drives the oil pump body to work through the crankshaft. The oil pump body and the oil circuit are integrated in the accessory bracket and connected to the main oil circuit of the engine. The oil pump rotor is installed on the crankshaft and can adjust the lubricating oil amount in real time as the crankshaft speed changes. The accessory bracket is integrated with a water pump body, an oil pump body, etc., so that the engine volume is further reduced.
[0019] Embodiment: Figure 1 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing diesel engine accessory bracket oil pump is independently installed and mainly driven by gear transmission. On the one hand, there is wear at the gear meshing. If the wear is serious, the transmission ratio changes, which affects the engine oil supply. The overall idea is as follows:
[0020] In view of the problems existing in the prior art, the utility model provides a diesel engine accessory bracket, including a bracket body, an oil inlet 1 is arranged at the bottom of the bracket body, an oil inlet 2 is arranged at the bottom of the bracket body, an oil pump body 4 is installed on the bracket body, an oil pump rotor 3 is arranged in the oil pump body 4, a water pump body 5 is installed on the bracket body, a water channel 6 is arranged on the bracket body, the water channel 6 is connected with the water pump body 5, the oil pump rotor 3 is installed on the engine crankshaft, a diesel pump plugging cover 7 is installed on the bracket body, the diesel pump plugging cover 7 is used to protect and fix the diesel pump parts, a filter 8 is installed on the oil inlet 1, the filter 8 is connected with the oil inlet 2, the filter 8 is used to filter the oil, the water pump body 5 is responsible for the water flow in the circulating water channel 6, the inlet end of the oil pump body 4 is connected with the oil inlet 1, and the outlet end of the oil pump body 4 is connected with the oil inlet 2.
[0021] Working principle:
[0022] In the first step, when the oil pump body 4 is working, the oil is sucked from the oil pan into the oil inlet 1, passes through the oil pump body 4 and enters the engine from the oil inlet 2 for lubrication. When the engine is working, the crankshaft drives the oil pump rotor 3 to rotate, and a closed cavity is formed between the inner and outer rotors. When it rotates from the oil inlet 1, the volume increases, a vacuum is generated, and the lubricating oil is sucked in through the oil inlet. When the cavity for sucking the lubricating oil is connected to the oil outlet, the volume of the cavity decreases, the oil pressure increases, and the lubricating oil is pressed out from the oil outlet. The engine keeps running, forcing the lubricating oil to circulate along the prescribed path. Moreover, when the oil pressure of the oil pump body 4 is too large or too small, the pressure limiting valve is opened or closed, and the oil pump body 4 is integrated into the accessory bracket. A rotor-type oil pump body 4 is adopted, and the oil pump rotor 3 is installed on the engine crankshaft. The oil pump body 4 is directly driven to work by the crankshaft. The oil pump body 4 and the oil circuit are integrated into the accessory bracket and connected to the main oil circuit of the engine. The accessory bracket is integrated with a water pump body 5, an oil pump body 4, etc., so that the engine volume is further reduced. The oil pump rotor 3 is installed on the crankshaft, and the amount of lubricating oil can be adjusted in real time as the crankshaft speed changes.
