[0032] As Figures 1 - 5 As commonly shown, this embodiment provides an oil pressure housing for an automotive intelligent transmission. This oil pressure housing for an automotive intelligent transmission includes a base shell 1 and an output shaft 2 provided at the upper end of the base shell 1. It is characterized in that: an output hole 3 is opened in the middle of the output shaft 2, and an installation component 7 is connected to the lower end of the base shell 1, and a seat body component 8 is inserted into the lower end of the installation component 7;

[0033] The installation component 7 includes an installation frame 71 fixedly provided on the lower end surface of the base shell 1. Two groups of symmetrically arranged collar grooves 72 and receiving grooves 73 are respectively opened downward from top to bottom at the lower end of the installation frame 71. The seat body component 8 includes a seat body 81 inserted into the inner wall of the lower end of the installation frame 71. Two groups of symmetrically arranged fixing plates 82 are provided on the outer wall of the seat body 81. A fixing block 83 is provided in the middle of the fixing plate 82. Two groups of symmetrically arranged springs 84 are respectively provided at both ends of the fixing block 83, and an installation block 85 is provided at the end of the spring 84 away from the fixing block 83.

[0034] The seat body 81 is movably inserted into the inner wall at the lower end of the mounting frame 71, the fixing plate 82 is movably inserted into the collar groove 72, the mounting block 85 is movably inserted into the receiving groove 73, the outer wall of one end of the mounting block 85 close to the spring 84 is movably inserted into the inner wall of the fixing plate 82, an annular groove is formed in the middle of the mounting block 85, the mounting block 85 can slide along the annular groove, and an inclined surface 86 inclined downward is formed at one end of the mounting block 85 away from the spring 84.

[0035] The seat body assembly 8 further includes a bolt 87 threadedly inserted into the outer wall of the seat body 81, and a threaded hole 74 matching with the bolt 87 is formed in the outer wall of the mounting frame 71.

[0036] A plurality of groups of receiving bins 88 for accommodating speed change gears are evenly formed at the bottom end of the seat body 81.

[0037] When the housing fails and needs to be repaired, the staff removes the bolt 87 from the threaded hole 74, and then the staff can push the mounting block 85 into the fixing plate 82. The two mounting blocks 85 approach each other along the annular groove. When the mounting block 85 leaves the receiving groove 73, the seat body 81 is pulled downward, and the seat body 81 is pulled out from the inner wall of the mounting frame 71, so as to quickly separate the seat body 81 from the base shell 1, thereby facilitating the repair of the interior of the device. After the device is maintained, the fixing plate 82 is pushed upward along the collar groove 72, and the seat body 81 is inserted into the inner wall at the lower end of the mounting frame 71. During the insertion process, the inclined surface 86 contacts the two lower ends of the collar groove 72, and the two lower sides of the collar groove 72 push the mounting block 85 to slide along the annular groove into the interior of the fixing plate 82 and compress the spring 84. When the receiving groove 73 and the mounting block 85 are on the same horizontal plane, under the reverse elastic force of the spring 84, the mounting block 85 is inserted into the receiving groove 73, and then the bolt 87 is screwed into the threaded hole 74 again to complete the installation of the base shell 1 and the seat body 81, solving the problem that the base shell and the seat body of most current transmission oil pressure housings are integrally formed, and it is inconvenient for the staff to disassemble the base shell and the seat body.

[0038] As Figures 1 - 7 As shown together, an output shaft 2 is threadedly inserted into the upper end of the base shell 1, and a threaded groove matching with the output shaft 2 is formed in the upper end of the base shell 1.

[0039] An oil injection hole 5 penetrates through the upper end surface of the base shell 1. A connecting ring 4 is rotatably connected to the outer wall of the output shaft 2. The lower end of the connecting ring 4 abuts against the upper end surface of the base shell 1. A sealing plug 6 is fixedly arranged on the outer wall of one side of the connecting ring 4, and the sealing plug 6 is movably inserted into the inner wall of the oil injection hole 5.

[0040] A plurality of groups of reinforcing rods 9 that are symmetric to each other are fixedly arranged on the inner wall of the base shell 1. The reinforcing rods 9 are arranged at the inner corners of the inner wall of the base shell 1 and are arranged in an annular shape. Two groups of reinforcing rings 10 that are symmetric to each other are fixedly arranged in the middle of the reinforcing rods 9.

[0041] Oil can be injected into the interior of the transmission housing through the oil filling hole 5. Injecting oil can reduce the friction and wear between components such as gears and bearings inside the transmission, thereby extending the service life of the transmission. When the output shaft 2 is threadedly inserted into the upper end of the base housing 1 from top to bottom, the connecting ring 4 can be rotated so that the sealing plug 6 always aligns with the oil filling hole 5, and the sealing plug 6 is inserted into the oil filling hole 5 to prevent dust from entering the interior of the base housing 1 through the oil filling hole 5. The arrangement of the strengthening rod 9 and the strengthening ring 10 can significantly increase the strength and rigidity of the base housing 1, which helps to prevent the base housing 1 from deforming, twisting or being damaged when stressed, thus ensuring the stability and durability of the device. The strengthening rod 9 and the strengthening ring 10 are made of flat steel Q345B material. Q235B is a relatively common low-carbon structural steel with good plasticity and weldability.

[0042] It should be understood that the use of these embodiments is only for illustrating the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
