Technical Field

[0001] The utility model relates to the field of automatic transmissions, in particular to a loosening prevention device for fasteners used in automotive transmissions. Background Art

[0002] With the rapid development of the automotive industry, automatic cars with automatic transmissions are becoming increasingly popular because they can automatically shift gears and torque according to road conditions without manual shifting. In addition, they can also play a role in dust prevention, preventing external dust and impurities from entering the transmission. The transmission oil not only lubricates, cleans, rust-proofs, and dissipates heat, but also plays a crucial role in keeping the gear system clean.

[0003] There is a relatively high risk of oil leakage at the connection between the externally installed sensor and the transmission housing of the existing automatic transmission, resulting in a reduction in the oil volume of the housing, insufficient lubrication, high temperatures in the rotating parts that require lubrication, component burnout, and thus a decline in the transmission function. To solve the above problems, a loosening prevention device for fasteners used in automotive transmissions is proposed. Summary of the Utility Model

A nut 29 is threadedly connected to the outside of the screw 28. The nut 29 fixes the screw 28.

[0035] Referring to Figures 4 to 6 , a baffle 20 is fixedly connected to the right side of the push rod 14. The push rod 14 pushes the baffle 20 to seal or open the oil pipe 18.

A limiting plate 23 is detachably connected inside the bottom plate 22. The baffle 20 is slidably connected inside the fuel pipe 18. An inclined push block 30 is in contact with the bottom of the screw 28. The outside of the inclined push block 30 is slidably connected inside the second push block groove 32 for limiting the inclined push block 30. The inclined push block 30 slides into the second push block groove 32 inside the bottom plate 22 to fix the bottom plate 22 and the transmission 1. A limiting groove 25 is provided inside the limiting plate 23 for the limiting block 24 to enter and fix the limiting plate 23 and the bottom plate 22.

[0036] Working principle: First, the motor 10 transmits power to the push rod 12 through the rotating rod 11. The push rod 12 then pushes the sliding block 5 for adjustment. The sliding block 5 can move inside the base 3 through the sliding card slot 4 of the base 3, thereby adjusting the positions of the fixed column 6 and the stopper 7. This adjustment allows the automatic oil dripping assembly to accurately align with the area to be sealed. The rotating frame 13 provides an additional rotating function to move and adjust the stopper 7. Through the coordinated work of the mechanical structure and the power device, the automatic oil dripping assembly ensures that the oil in the fuel tank 17 enters the gearbox regularly and quantitatively. The automatic oil dripping assembly can continuously supply lubricating oil to the equipment or mechanical components to ensure that all moving parts are properly lubricated. This helps to reduce friction and wear and extend the service life of the equipment.

[0037] Secondly, the gearbox 1 is installed on the bottom plate 22. The left and right sides inside the gearbox 1 are connected by screws 28 and nuts 29, making the connection between the bottom plate 22 and the gearbox 1 more fixed. The bottom of the screw 28 contacts the inclined push block 30. When the screw 28 descends, it pushes the inclined push block 30, causing the inclined push block 30 to enter the inside of the bottom plate 22, making the bottom plate 22 and the gearbox 1 tightly fixed. The limiting plate 23 is slidably connected inside the bottom plate 22. The limiting plate 23 is fixed to the bottom plate 22 and the gearbox 1. The limiting block 24 is detachably connected inside the limiting plate 23. The limiting groove 25 is provided on the limiting plate 23 to ensure the stability of the limiting block 24 at a specific position. The push block groove one 31 and the push block groove two 32 are arranged on the left and right sides of the gearbox 1. The inclined push block 30 slides into the inside of the push block groove two 32 and cooperates with the bottom groove 27 and the limiting card slot 26 on the bottom plate 22 to ensure that the fasteners of the transmission will not become loose due to vibration or other reasons during the working process.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
