Abstract
Description
Technical Field
[0001] The utility model relates to a filter, in particular to a pressure filter integrating filtering and cooling functions. Background Art
[0002] In an automotive transmission system, components such as rolling bearings and shaft gears continuously generate a large amount of heat during operation, and this heat needs to be effectively and timely removed. Currently, a cooling lubrication system is used to cool the components that need to be cooled at fixed points. The cooling lubrication system generally includes a suction filter, an oil pump, a condenser, a pressure filter, and an oil injection pipeline. Under the action of the oil pump, the oil fluid passes through the suction filter, the oil pump, the condenser, the pressure filter, and the oil injection pipeline in sequence, and then sprays out from the oil injection holes on the oil injection pipeline. Among them, the suction filter, the oil pump, the condenser, and the pressure filter are centrally arranged in one place, and the oil injection pipeline is generally connected to the pressure filter through a connecting pipeline. However, due to insufficient installation space, it is necessary to optimize the installation position of the pressure filter in the cooling lubrication system in the automotive transmission system.

The housing 5 of the filter press is made of the same material as the inlet pipe 1 and the outlet pipe 2, and preferably plastic. The inlet pipe 1 and the outlet pipe 2 are integrally arranged on the housing 5. To improve the structural strength of the housing 5, the inlet pipe 1 and the outlet pipe 2 and prevent the inlet pipe 1 and the outlet pipe 2 from shaking, reinforcing rib plates 4 are integrally arranged on the housing 5, the inlet pipe 1 and the outlet pipe 2.
[0017] Among them, the reinforcing rib plate 4 between the housing 5 and the inlet pipe 1 is integrally connected, and the reinforcing rib plate 4 between the housing 5 and the outlet pipe 2 is integrally connected. For the convenience of assembly, the housing 5 of the filter press is composed of an upper housing 51 and a lower housing 52 which are butt-jointed up and down. After the lower housing 52 and the upper housing 51 are butt-jointed, they are fixedly connected by bolts. The upper housing 51 is a trough structure with an opening downward, and the lower housing 52 is a trough structure with an opening upward. The butting port at the upper end of the lower housing 52 and the lower end of the upper housing 51 is sealed.

The filter cartridge 6 of the filter press is vertically fixedly arranged in the housing 5. The central hole 61 of the filter cartridge 6 is connected and communicated with the inner end port of the oil outlet 53. A bypass valve 63 is arranged at the lower end of the central hole 61 of the filter cartridge 6. A first gap is left between the side wall of the filter cartridge 6 and the inner wall of the housing 5.

[0019] During operation, the oil first enters the first and second gaps inside the housing 5 through the inlet pipe 1, and then enters the central hole 61 of the filter cartridge 6 after being filtered by the filter medium of the filter cartridge 6. Meanwhile, when the bypass valve 63 reaches its opening pressure, the bypass valve 63 will open; the filtered oil is discharged through the outlet pipe 2; and the corresponding components in the automotive transmission system are sprayed with oil for cooling through the spray holes 3 at different positions on the inlet pipe 1 and the outlet pipe 2.
