Technical Field
[0001] The utility model relates to the technical field of bevel planetary gear type differentials, in particular to a symmetrical bevel planetary gear type differential. Background Art
[0002] When a car is driving, the turning radius of the wheels on both sides is different, or the rotation speeds of the wheels on both sides are different when they are driving on slopes at different angles. The differential is a device to adapt to the speed difference between the wheels on both sides, allowing the left and right half-axles to rotate at different speeds, so that the drive wheels roll relative to the ground instead of sliding, and at the same time transmit the power of the main reducer to the left and right half-axles.
[0003] However, most bevel planetary gear differentials will usually cause wear of the gears inside the differential after long-term use, which requires lubricating the gears after long-term use. Most of the time, the housing needs to be disassembled when adding lubricating oil, which makes it inconvenient to add lubricating oil to the inside of the bevel planetary gear differential.

[0010] Preferably, a limiting block is connected through the interior of the mounting plate, and an extrusion rod is arranged inside the limiting block.
[0011] Compared with the prior art, the beneficial effect of the utility model is that the symmetrical bevel planetary gear differential can move the pressing seat by pressing the pressing seat, so that the pressing seat can move the first tooth plate connected on one side when moving, so that the first tooth plate can move the second tooth plate through the rotating gear connected on one side when moving, so that the second tooth plate can move the connected sealing plate when moving, so that the sealing plate can allow the lubricating oil stored in the oil tank to enter the shell when moving, so that the gears inside the shell can be lubricated, so that the bevel planetary gear differential can solve the above-mentioned problem of being difficult to add lubricating oil when in use.
[0012] 1. The symmetrical bevel planetary gear differential is usually not easy to add lubricating oil to the inside when it is in use.

[0013] 2. The symmetrical bevel planetary gear differential, when the bevel planetary gear differential is in use, usually the lubricating oil used to lubricate the surface of the internal gears is easy to fall to the bottom during use, which makes it easy to waste more lubricating oil when the bevel planetary gear differential is in use. The lubricating oil can be discharged through the discharge port opened at the bottom of the shell, and the shell is connected through the mounting plate, and the mounting plate is connected to the shell through the limiting block, and then the extrusion rod is connected to the mounting plate, so that the extrusion rod can squeeze the limiting block when pushing, so that the limiting block can lock the mounting plate and the shell, so that the collection box can be installed, and then the collection box can collect the discharged lubricating oil, so that the bevel planetary gear differential can be more convenient when in use.

[0021] When it comes to specific implementation,
[0022] See also Figure 1 , Figure 2and Figure 3 It can be known that when the bevel planetary gear differential is in use, it is usually not easy to add lubricating oil to the inside. By pressing the pressing seat 9, the pressing seat 9 can be moved, and then the pressing seat 9 can move the first toothed plate 10 connected on one side when moving, so that the first toothed plate 10 can move the second toothed plate 12 through the rotating gear 11 connected on one side when moving, so that the second toothed plate 12 can move the connected sealing plate 13 when moving, so that the sealing plate 13 can make the lubricating oil stored in the oil tank 7 enter the inside of the housing 1 when moving, so that the gears inside the housing 1 can be lubricated, so that the bevel planetary gear differential can avoid being disassembled as a whole when adding lubricating oil;
