Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspension structures, in particular to an automobile suspension structure which can prevent a bolt shaft from loosening. Background Art

[0002] Among various automotive suspension structures, one type mounts the wheel axle on a swing arm hinged to the vehicle frame, with a buffer device connected between the swing arm and the frame. As the vehicle moves, the swing arm swings up and down around the hinged axis as the wheel jolts. In this existing automotive suspension structure, the hinged axis between the swing arm and the frame is a bolted shaft, and self-locking nuts or spring washers are used to prevent the bolt from loosening. However, these self-locking nuts and spring washers are not ideal, and the bolt often loosens.

[0003] To address the above-mentioned problems, a utility model with a published patent number of CN203063607U discloses a vehicle suspension structure that can prevent a bolt shaft from loosening, comprising a swing arm connected to a wheel axle, the swing arm being hinged to a vehicle frame, the hinged axis being a bolt shaft, a nut being screwed onto the bolt shaft, a snap ring being provided on the vehicle frame, the snap ring being circumferentially fixed and unable to rotate, the snap ring having a non-circular hole, the non-circular hole being sleeved over a portion of the non-circular cross section of the bolt shaft, the snap ring and the bolt shaft forming a circumferentially fixed hole-axis fit. The utility model can reliably prevent the bolt shaft from loosening, thereby improving the safety of the vehicle suspension structure; however, there are still some shortcomings. Existing anti-loosening structures mostly adopt a single anti-loosening method. However, under the condition that the vehicle suspension is driven for many years, the single anti-loosening structure still has the possibility of failure. In addition, the existing bolts are prone to reverse when the vehicle vibrates during driving, posing a significant safety hazard. Utility Model Content

[0023] Reference Figure 1-5 A vehicle suspension structure that can prevent a bolt shaft from loosening includes a frame base 1, a rocker arm 2 is rotatably mounted on the inner side of the frame base 1, and mounting holes are provided on one side of the frame base 1 and the rocker arm 2; a same bolt shaft 3 is slidably mounted in both mounting holes, and a ratchet groove is provided on one side of the frame base 1; a fixed ratchet 5 is slidably mounted on the inner side of the ratchet groove, and a limit spring 7 is fixedly mounted on one side of the fixed ratchet 5.

[0024] In this embodiment, the other end of the limit spring 7 is connected to the inner wall of one side of the ratchet groove, and a receiving groove is provided on one side of the fixed ratchet 5.

[0025] In this embodiment, a mounting nut 6 is fixedly installed on the inner side of the receiving groove, and the mounting nut 6 is threadedly connected to the bolt shaft 3.

[0026] In this embodiment, a cross slot 8 is formed at one end of the bolt shaft 3 .

[0027] In this embodiment, a limiting ratchet 4 is provided on the outer fixing sleeve of the bolt shaft 3 . The limiting ratchet 4 is matched with the fixing ratchet 5 to facilitate limiting the position of the bolt shaft 3 and prevent it from reversing.

[0028] In this embodiment, a nut base 9 is fixedly mounted on one side of the frame base 1 .

[0029] In this embodiment, a squeeze plate 10 is slidably mounted on the inner side of the nut base 9 , a plurality of liquid outlet holes 11 are opened on one side of the squeeze plate 10 , and a plurality of thorn cones 12 are fixedly mounted on one side of the squeeze plate 10 to facilitate puncturing a plurality of capsules 15 .

[0030] In this embodiment, a support spring 13 is fixedly installed on one side of the extrusion plate 10, and the other end of the support spring 13 is connected to the inner wall of one side of the nut base 9, so as to support the extrusion plate 10 and prevent it from puncturing multiple capsules 15 without being squeezed.

[0031] In this embodiment, a limiting nut 14 is fixedly installed on the inner side of the nut base 9 , and the limiting nut 14 is adapted to the bolt shaft 3 .

[0032] In this embodiment, a plurality of capsules 15 are fixedly mounted on the inner wall of one side of the nut base 9 , and the plurality of capsules 15 are all filled with thread locking glue, so as to facilitate fixing the bolt shaft 3 .

[0033] Working principle: During installation, the staff aligns the mounting holes of the frame base 1 and the rocker arm 2, and then rotates the bolt shaft 3. The rotation of the bolt shaft 3 drives the limiting ratchet 4 to rotate. Since the rotation direction of the limiting ratchet 4 is consistent with the tooth groove direction on the fixed ratchet 5 during installation, the fixed ratchet 5 will not limit the limiting ratchet 4 at this time. The bolt shaft 3 is threadedly connected with the mounting nut 6 on one side of the fixed ratchet 5. Therefore, the bolt shaft 3 slides into the mounting holes of the frame base 1 and the rocker arm 2. When the bolt shaft 3 passes through the mounting holes of the frame base 1 and the rocker arm 2, one end of the bolt shaft 3 contacts the limiting nut 14 fixedly installed on the inner side of the nut base 9, and the two are threadedly connected, so the bolt shaft 3 moves toward the nut The female base 9 slides inside, and the bolt shaft 3 is in contact with the extrusion plate 10 at this time, and the extrusion plate 10 is squeezed to move the extrusion plate 10. The movement of the extrusion plate 10 drives the multiple thorn cones 12 to move and puncture the multiple capsules 15 on the inner side of the nut base 9. At this time, the thread locking glue in the multiple capsules 15 flows out and flows out through the multiple liquid outlet holes 11 on the surface of the extrusion plate 10, and contacts the bolt shaft 3. At this time, the bolt shaft 3 rotates to the specified position, and the limiting ratchet 4 squeezes the fixed ratchet 5, but at this time the limiting spring 7 has reached the maximum contraction degree, so the limiting ratchet 4 cannot continue to rotate and squeezes the fixed ratchet 5, and the fixed ratchet 5 limits the limiting ratchet 4 to prevent it from reversing.

[0034] The technical progress achieved by the present invention over the prior art is that: through the provided mechanism, the thread locking glue and the ratchet design can effectively prevent the bolt shaft 3 from loosening, and the use of the ratchet can also effectively prevent the bolt shaft 3 from being reversed due to long-term vibration after the vehicle has been running for a long time, thereby greatly improving the stability and safety of the vehicle suspension.
