Detailed ways

The present invention will be described in further detail below with reference to the drawings and embodiments.

Referring to Figures 1 to 4, it can be known that the present invention is applied to the integrated oil lubrication module assembly of the engine, which includes a filter element 8 and an oil cooler 3, and the filter element 8 (on the top, including the end cover) passes through the filter element holder 6 ( Down) is set in the upper part of the module housing 1 (that is, the upper part of the module housing 1 has a box-like structure), the oil cooler 3 is installed on the module housing 1 (middle and lower parts), and the module housing The body 1 has a coolant inlet 16, a coolant outlet 17, and an oil inlet 18 that communicate with the oil cooler 3, and the module housing 1 has an oil filter that communicates with the filter element 8 and the filter element bracket 6 respectively. Clear inlet 19 (and engine oil filter inlet pipeline 23), engine oil filter outlet 20.

Wherein, the upper part of the module housing 1 can also be equipped with a sealing cover 9 to cover the filter element 8 . The coolant outlet 17 is adjacent to the oil inlet 18 , and the coolant inlet 16 is adjacent to the oil filter inlet 19 and the oil filter outlet 20 . The coolant inlet 16, the oil filter inlet 19, and the oil filter outlet 20 between the module housing 1 and the oil cooler 3 are provided with first seals 4 for sealing. The coolant outlet 17 and the oil inlet 18 between the oil coolers 3 are provided with a second seal 2 for sealing.

In order to better perceive the temperature of the engine oil at its filter inlet and the pressure of the oil pump when the oil is output, an oil temperature sensor 5 is installed on the module housing 1 and at (close to) the oil filter inlet 19, An oil pump installation position 10 is provided on the module housing 1 , and an oil pressure sensor 12 is installed on the module housing 1 (near) the oil pump installation position 10 . On the module housing 1 and below the oil pump installation position 10, a transmission belt tensioner installation position 11 is provided to facilitate the installation of the power transmission belt tensioner.

As shown in Figures 1 and 4, the unfiltered oil is recovered when the filter element is replaced as required, and the module housing 1 has an unfiltered oil outlet 21 (and an unfiltered oil passage adjacent to the oil filter outlet 20) 22), on the filter element 8, and connected with the filter element support 6 and close to the unfiltered oil outlet 21, an oil return plug 26 (it is on the end cover of the filter element); on the filter element support 6 It has an oil filter outlet pipeline 24 and an oil return pipeline 25 respectively correspondingly connected with the engine oil filter outlet 20 and the oil return plug 26 . When working normally, the oil return plug on the end cover of the filter element seals the oil return pipe to avoid the waste of oil flowing out from the oil return pipe; when the filter element is blocked or needs to be replaced, it can be pulled out directly, and the oil return pipe is opened at the same time. The remaining unfiltered engine oil in the filter element will flow out from the oil return pipeline and the unfiltered engine oil outlet for the next filtering.

In order to better control the oil intake of the engine oil and facilitate the intake of the coolant, and prevent the oil from flowing back when the engine is shut down, an oil inlet check valve 14 ( And sealing ring 15), on the coolant inlet 16 (the other side) of the module housing 1, a coolant pipe joint 13 (which is connected to the coolant tank through the coolant pipe) is installed.

A bypass valve 7 is installed on the filter element bracket 6 (it is placed outside the filter element, and the bypass valve does not need to be replaced when replacing the filter element), and the bypass valve 7 faces the oil filter outlet pipe 24 of the filter element bracket 6 . Once the filter element is overloaded or fails, the bypass valve will automatically open under the pressure generated by the oil to ensure sufficient oil supply in the oil circuit and ensure the normal operation of the engine under abnormal conditions. The filter element is a one-time special filter element. When the life of the filter element is terminated, only the filter element needs to be replaced, and all the structures of the module assembly of the present invention will not change, so that the impact on the environment is minimized, greatly Improved environmental protection. Since the module assembly is vertically installed on the side of the engine, the filter element is on the upper part for the convenience of filter element replacement.

The integral oil lubricating module assembly of the present invention is designed according to the needs of the engine (especially the VM engine developed by the Italian VM company), and is especially suitable for the VM engine.

The oil filtering and lubricating method obtained by the integral oil lubricating module assembly of the present invention is as follows: first, the machine oil (through the oil pump) enters the machine oil cooler from the machine oil inlet 18 (through the oil inlet check valve) on the module housing, and then The oil cooler enters the filter element 8 (and the filter element support 6) through the oil filter inlet 19 (and the oil filter inlet pipe 23) on the module housing for filtering; at the same time, the coolant (through the coolant pipe) flows from the module housing The coolant inlet 16 on the top enters the oil cooler, and then returns to the coolant tank through the coolant outlet 17 on the module shell. At this time, the engine oil and coolant pass through the oil cooler at the same time, and exchange heat in the oil cooler. The temperature of the original engine oil is high and the temperature of the coolant is low. After heat exchange, the temperature of the engine oil decreases and the temperature of the coolant increases (to achieve the purpose of cooling the engine oil). After being filtered by the filter element, the cooling oil passes through the oil filter outlet on the module shell 20 into the car engine to play a role in lubrication. In order to simultaneously grasp the temperature and oil pressure of the oil passing through the module housing, the oil temperature sensor and oil pressure sensor installed on the module housing are used for sensing; when the oil temperature is too high or too low, the oil temperature sensor will issue a warning , to adjust the oil temperature to a suitable temperature, according to the oil pressure sensor, you can check the use of the filter element and check the oil volume at any time.

According to the structural characteristics of the integral oil lubrication module assembly, combined with the structure of the VM engine, the installation position of the oil pump and the conveyor belt tensioner are also set on the installation side of the module housing. After the engine, the oil pump on the engine and the belt tensioner can also be installed on the module assembly, so as not to occupy the space of the engine.
