DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figure 1-Figure 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 yes Figure 1 Sectional view along line AA; Figure 3 yes Figure 2 Enlarged view of point B in the middle.

[0022] The utility model provides a self-lubricating differential assembly structure: comprising a right housing 101, a left housing 102, a left half-shaft gear 103, a right half-shaft gear 104 and a self-lubricating mechanism, wherein the self-lubricating mechanism comprises two self-lubricating bearings 105, two mounting support sleeves 106, a lubricating component and a filtering component, wherein the lubricating component comprises an injection port 107, a storage cavity 108, a discharge port 109, a sealing plug 110 and a micro motor 111, and the filtering component comprises a storage box 112, an asbestos layer 113 and an activated carbon layer 114. The above-mentioned scheme solves the problem that the above prior art cannot directly lubricate the inside and needs to be disassembled for lubrication, but the differential is troublesome to disassemble and assemble, and the lubrication is inconvenient.

[0023] According to the present specific embodiment, the left housing 102 is fixedly connected to one side of the right housing 101, the left half-shaft gear 103 is located in the left housing 102, the right half-shaft gear 104 is located in the right housing 101, the two self-lubricating bearings 105 are respectively rotatably connected to the left half-shaft gear 103 and the right half-shaft gear 104, and are respectively rotatably connected to the right housing 101 and the left housing 102, the two mounting support sleeves 106 are respectively rotatably connected to the right housing 101 and the left housing 102, and the lubrication assembly is located in the right housing On the body 101, the filter assembly is located below the right housing 101. When the differential is working, under the action of the two self-lubricating bearings 105, the left half-shaft gear 103 and the right half-shaft gear 104 rotate more smoothly. The shaft connected to the left half-shaft gear 103 and the right half-shaft gear 104 rotates more smoothly under the action of the two mounting support sleeves 106, so that the differential has a certain self-lubricating function. When lubrication is needed, the lubrication assembly can be started for lubrication. The used lubricant will be collected and filtered by the filter assembly for reuse.

[0024] Among them, the injection port 107 is fixedly connected to the top of the right housing 101, the storage chamber 108 is arranged in the right housing 101 and is communicated with the injection port 107, and the discharge port 109 is fixedly connected in the right housing 101 and is communicated with the storage chamber 108. Before use, the lubricant is injected into the storage chamber 108 through the injection port 107, and when lubricating, the lubricant is discharged from the discharge port 109 into the right half-shaft gear 104 in the right housing 101. Because the internal gears of the differential are meshed with each other, the lubricant diffuses as the gears rotate until a lubricating layer is formed on the surface of the gear, and the lubrication is completed.

[0025] Secondly, the sealing plug 110 is hinged below the discharge port 109, and the output end of the micro motor 111 is fixedly connected to the sealing plug 110 and fixedly connected to the right shell 101. When lubricating, the micro motor 111 is started to open the sealing plug 110. At this time, the lubricant in the storage cavity 108 will enter the right shell 101 from the discharge port 109 for lubrication.

[0026] At the same time, the storage box 112 is fixedly connected to the bottom of the right shell 101 and is connected to the inside of the right shell 101. The asbestos layer 113 is fixedly connected to the top of the storage box 112. The activated carbon layer 114 is fixedly connected to the bottom of the asbestos layer 113. After lubrication, the lubricant will flow into the storage box 112 from the bottom of the right shell 101. When flowing in, it first passes through the asbestos layer 113 to remove impurities, and then passes through the activated carbon layer 114 to remove odor factors, and finally gathers at the bottom of the storage box 112 to wait for recycling.

[0027] Before using the differential, the lubricant is injected into the storage cavity 108 through the injection port 107 for direct use. When the differential is working, under the action of the two self-lubricating bearings 105, the rotation of the left half-shaft gear 103 and the right half-shaft gear 104 is smoother. The shaft connected to the left half-shaft gear 103 and the right half-shaft gear 104 rotates more smoothly under the action of the two mounting support sleeves 106, so that the differential has a certain self-lubricating function. When lubrication is required, the micro motor 111 is started to open the sealing plug 110. At this time, the lubricant in the storage cavity 108 will enter the right housing 101 from the discharge port 109. On the right half-shaft gear 104 inside, because the internal gears of the differential are meshed with each other, the lubricant diffuses as the gears rotate until a lubricating layer is formed on the surface of the gears, and the lubrication is completed. The lubricant after lubrication will flow into the storage box 112 from the bottom of the right housing 101. When flowing in, it first passes through the asbestos layer 113 to remove impurities, and then passes through the activated carbon layer 114 to remove odor factors, and finally gathers at the bottom of the storage box 112 to wait for recycling. This avoids the problem that the prior art cannot directly lubricate the inside and needs to be disassembled for lubrication, but the differential is troublesome to disassemble and assemble, and the lubrication is inconvenient, and the effect of recycling lubricants, self-lubrication and convenient lubrication is achieved.

[0028] The second embodiment of the present application is:

[0029] See also Figure 4-Figure 5 ,in Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the utility model; Figure 5It is a structural schematic diagram of the auxiliary mechanism of the second embodiment of the utility model.

[0030] On the basis of the first embodiment, the self-lubricating differential assembly structure of this embodiment further includes an auxiliary mechanism, which includes a threaded plug 201 , a sealing gasket 202 and a torsion plate 203 .

[0031] Among them, the threaded plug 201 is threadedly connected in the injection port 107, the sealing gasket 202 is fixedly connected to the bottom of the threaded plug 201, and the twisting disk 203 is fixedly connected to the top of the threaded plug 201. When the lubricant of the differential is insufficient, the twisting disk 203 is twisted to twist the threaded plug 201 out of the injection port 107 and the sealing gasket 202. At this time, lubricant can be added from the injection port 107. After the filling is completed, the threaded plug 201 and the sealing gasket 202 can be twisted back to the injection port 107, so as to protect the injection port 107 and effectively prevent dust from falling into, causing the injection port 107 and the discharge port 109 to be blocked.
