Beneficial effects of the present invention: the integrated oil cooling and filtering structure adopts an integrated design, which can save the arrangement space of parts. At the same time, compared with separate parts, the integrated design can effectively reduce the weight. At the same time, the integrated design reduces the use of seals and improves sealing. The parallel coolant flow design is adopted to change the flow direction of the engine coolant. Compared with the series circulation, the parallel circulation has less resistance to the cooling system during the entire coolant circulation process. The small resistance of the system means that the cooling system has a small demand for the head of the water pump, and the power consumption of the water pump is small, which is beneficial to reduce the fuel consumption of the engine.

Detailed ways

In order to describe the technical content, achieved goals and effects of the present invention in detail, the following will be described in conjunction with the embodiments and accompanying drawings.

Implementation mode 1:

An integrated oil cooling and filtering structure, including a cooling and filtering housing 1 and a cooler core 2, the cooler core 2 is arranged at the bottom of the cooling and filtering housing 1, and one side of the cooling and filtering housing is integrated A centrifugal oil filter 3 and a paper oil filter 4 arranged coaxially are provided, and the cooling filter housing 1 is equipped with a filter that can lead the cooling liquid to the cooler core 2 and the body cylinder respectively. The first shunt structure 5 in the cover; the other side of the cooling filter housing 1 is provided with a water pump volute 6 module that can be connected to the water pump, and communicates with the first shunt structure 5. The cooling filter housing 1. A tensioning wheel bracket 7 for installing a tensioning wheel is provided on the side close to the water pump volute 6 module at the bottom, and the tensioning wheel can be used to adjust the tension of the belt.

Working principle: The oil circuit of the engine oil is that the oil output from the oil pump flows into the integrated oil cooling and filtering structure from the oil inlet 11, flows into the centrifugal oil filter 3 and the paper oil filter 4 arranged coaxially, and passes through the centrifugal oil filter. The oil filtered by the type oil filter 3 flows into the oil pan, and then communicates with the oil pump to form an oil return passage. The machine oil filtered by the paper oil filter 4 flows into the cooler core 2 and finally flows into the machine oil outlet 12 and enters the main oil passage of the machine oil. The flow path of the coolant is: the coolant in the radiator of the water tank flows into the first split flow structure 5 through the volute of the water pump, and is divided into two streams of coolant, one flows to the cylinder head of the body to cool the cylinder head of the body, and the other flows to the cooling The core 2 cools the engine oil. The cooled coolant flows back to the radiator of the radiator to complete the cycle. Compared with series circulation, this kind of coolant parallel circulation has less resistance in the cooling system during the entire coolant circulation process. The small resistance of the system means that the cooling system has a small demand for the head of the water pump, and the power consumption of the water pump is small, which is beneficial to reduce the fuel consumption of the engine.

In addition, the function of the paper oil filter 4 and the centrifugal oil filter 3 is to filter the impurities in the oil, so as to ensure that the parts are not worn and prolong the service life of the oil. The tension pulley support 7 effect is to fix the tension pulley in the front end pulley train. The cooler core 2 is a place for heat exchange between the coolant and the engine oil, and is used for cooling the engine oil. The water pump volute 6 is a space that seals the water pump impeller, so that the coolant can be sucked in and pressed out by the action of the impeller. The role of the cooling filter housing is to support and carry the various sub-components.

The integrated oil cooling and filtering structure adopts an integrated design, which can save the layout space of parts. At the same time, compared with separate parts, the integrated design can effectively reduce the weight. At the same time, the integrated design reduces the use of seals and improves sealing.

The function of the one-way valve 8 is to prevent the engine oil from returning after shutdown, so as to prevent the oil from needing to refill the module when the engine is restarted, and reduce the dry friction of internal parts.

Implementation mode 3:

On the basis of Embodiment 1, the integrated oil cooling and filtering structure also includes an oil temperature control valve 10, and the oil filtered by the paper oil filter 4 is respectively communicated with each other through the oil temperature control valve 10. Cooler core 2 and oil inlet 12. The function of the oil temperature control valve 10 is to precisely control the temperature of the engine oil. When the temperature of the engine oil is low, the oil is controlled not to pass through the oil cooler core 2. The oil temperature is kept within a reasonable range.
