Description
Technical Field
The utility model belongs to the technical field of automobile design and manufacture, and particularly relates to a parallel double-oil-filtering oil collecting cavity structure.
Background
In the double-motor coupler of the new energy automobile hybrid system, the double motors and the heat exchange system have higher requirements on the cleanliness and the insulation performance of oil, so that the volume of oil filtration is required to be correspondingly increased in order to ensure that impurities containing metal particles in the oil can be filtered in time. In the conventional heat exchange system, an oil collecting cavity, an oil filter, an oil pump and a heat exchanger of a coupler assembly shell are connected in series through an oil circuit, as shown in fig. 1.
Considering working conditions such as ascending and descending slopes, the arrangement position of the oil filter needs to be at the lowest point of the assembly shell, and the common general oil filter is more difficult to arrange.
In order to meet the requirements of the system on the cleanliness and the insulation performance of oil, when the heat exchange system works, the oil filtering and sucking port connected with the oil pump in series is required to be always filled with the oil in the oil collecting cavity under any working condition, so that the air suction cannot be caused, and the cooling oil way is invalid. The volume of the oil collecting cavity required by the large-volume oil filter is also increased, and the arrangement scheme can only be realized by increasing the volume of the assembly shell, as shown in fig. 2.
The disadvantages of the integrated prior art are as follows:
(1) In a double-motor coupler of a hybrid system, both a double motor and a heat exchange system have higher requirements on the cleanliness and insulation performance of oil, so that the oil filtering volume is correspondingly increased;
(2) The volume of the single oil filter is extended to the periphery along with the increase of the filtering area, and the required oil filter space is larger;
(3) The oil filter needs to be arranged at the low point of the power assembly shell, and structures such as gears, gear shafts and guide ribs inside the assembly shell are avoided when working conditions such as ascending and descending are considered, so that the oil filter is more difficult to arrange;
(4) The oil collecting cavity on the shell of the coupling assembly is enlarged along with the large-volume oil filter;
(5) In order to meet the arrangement space of the oil filter and the oil collecting cavity, the volume of the shell of the mixing assembly needs to be increased, so that the volume, the weight and the cost of the assembly all rise along with the increase, and even the mixing assembly is difficult to meet the arrangement requirement of the engine room.
In the prior art, for a hybrid power assembly, a large torque and high power are required, and a huge heat dissipation system is matched with a high-performance motor, so that the volumes and the weights of the motor and the speed reducer are contradictory with a limited carrying space.

Detailed Description
The following detailed description of specific embodiments of the utility model is, but it should be understood that the utility model is not limited to specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
In consideration of the problems that the up-down slope and the left-right inclination working conditions possibly have larger influence on the design and arrangement positions of the oil collecting cavities and the stirring and the like of the motion of the differential gear ring and the gear shifting shaft gear set, the parallel double-oil-filtering oil collecting cavity structure is designed to be more reasonable in layout after the multi-working-condition model flow analysis.
As shown in fig. 3, the parallel double-oil-filter oil collecting cavity structure according to the preferred embodiment of the utility model comprises a tower-type oil filter 3-1, an oil pump oil suction cavity 3-2, a parallel oil duct 3-3 and a power assembly shell 3-4; the tower type oil filter 3-1 comprises a first tower type oil filter 3-1 and a second tower type oil filter 3-1, the first tower type oil filter 3-1 and the second tower type oil filter 3-1 are arranged at the bottom of the power assembly shell 3-4 in parallel, a parallel type oil duct 3-3 is arranged at the upper part of the power assembly shell 3-4, the parallel type oil duct 3-3 is connected with an oil pumping oil cavity 3-2, and the first tower type oil filter 3-1 and the second tower type oil filter 3-1 are connected with the oil pump oil absorption cavity 3-2 through the parallel type oil duct 3-3.
In an embodiment of the present utility model, the first tower type oil filter 3-1 and the second tower type oil filter 3-1 are in a revolving structure, and oil suction ports are arranged in the circumferential directions of the first tower type oil filter 3-1 and the second tower type oil filter 3-1, so that the arrangement space in the direction can be greatly reduced.
According to the parallel double-oil-filter oil collecting cavity structure, when the heat exchange system works, the oil pump is started, so that 2 tower-type oil filters 3-1 suck oil at the bottom of the power assembly shell 3-4 into the oil pumping oil cavity 3-2 through the parallel oil duct 3-3, and then the oil is conveyed to the heat exchanger through the oil duct at the other end of the oil pump, and pressurizing and oil conveying to the heat exchanger are completed. The oil suction port of the tower-type oil filter 3-1 is arranged in the circumferential direction, so that the arrangement space in the direction can be greatly reduced, and powerful guarantee can be provided for reducing the volume of the oil collecting cavity; in order to ensure that the 3-1 oil suction ports of the 2 tower-type oil filters are not sucked under the adverse conditions of turbulence generated by oil stirring of gear rings and gears at multiple working conditions such as up and down 17-degree slopes, forward and reverse rotation and the like, unique guide ribs are designed to be arranged around the double oil filters after multiple times of die flow analysis, and a parallel double oil filter oil collecting cavity structure is formed.
The parallel double-oil filter structure has the characteristics that the arrangement positions are relatively flexible, the structures such as a gear shifting assembly, a parking mechanism, a shell reinforcing rib and the like in the power assembly can be effectively avoided, and the arrangement space is optimized. However, because the oil suction port is changed into the circumferential direction and the double oil filters are connected in parallel, the phenomenon of suction is easy to occur under the working condition of ascending and descending at 17 degrees; the oil stirring effect is more easily caused by the forward and reverse rotation working conditions of the differential gear teeth and the middle teeth. Aiming at the problems, the method improves the multiple mode flow analysis results, and designs a unique oil collecting cavity structure for the parallel double-oil filter cloth bureau, as shown in fig. 4.
