Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock-absorbing steel leaf spring equipment, in particular to an automobile shock-absorbing steel leaf spring. Background Art

[0002] Leaf springs are commonly used shock-absorbing mechanisms in automobiles, with good shock-absorbing effects and high load-bearing capacity. The utility model patent with patent application number CN202321530319.6 discloses an automobile shock-absorbing leaf spring. By adding a buffer component to the leaf spring group, the two ends of the buffer component are blocked at the bottom and top of the leaf spring group by nuts and fixing seats respectively. This not only allows multiple leaf springs to maintain connection and avoid scattering of multiple leaf springs, but also allows the buffer component to be installed on the leaf spring group. When the car drives the leaf spring group to deform, the leaf spring group drives the screw and the pneumatic plug to move through the nut. The pneumatic plug can drive the negative pressure inside the vacuum sleeve to increase during the sliding process, thereby suppressing the excessive elastic deformation of the leaf spring group. This can assist the leaf spring group in bearing the pressure of the car and help the leaf spring group to quickly reset, thereby enhancing the shock absorbing effect of the leaf spring group and making the leaf spring less prone to permanent deformation. According to the technical solution disclosed by the invention, the existing automobile shock absorbing leaf spring equipment, on the one hand, cannot adapt to the installation and fixing work of support frames of different sizes, and thus cannot adapt to the installation and use on different vehicles, thereby reducing the adaptability of the equipment. On the other hand, after installation and fixing, the automobile shock absorbing leaf spring is easily loosened due to loose bolts, which is not conducive to ensuring the working safety of the automobile shock absorbing leaf spring.

When installing and fixing the leaf spring 1, the U-shaped screw 4 is first passed through the outer side of the leaf spring 1, the slide groove 5 on the support plate 3 and the slot 7 in the clamping plate 6 on both sides of the leaf spring 1 in turn. According to the width of the bottom support frame, the screw sleeve 9 is rotated, and the screw sleeve 9 drives the screw 8 to move inward or outward on the inner side of the screw sleeve 9 until the screw 8 drives the U-shaped screw 4 to clamp on the outer side of the support frame through the clamping plate 6, and then the nut 10 is screwed on the bottom end of the U-shaped screw 4 until the top of the nut 10 is clamped on the bottom of the clamping plate 6, and the top of the clamping plate 6 is clamped on the bottom of the support frame. It can adapt to the installation and fixation of fixing frames of different sizes, and can be installed and used on different vehicles, thereby improving the applicability of the equipment.

[0023] In this embodiment, the fixing frame 2 is sleeved on the outer side of the leaf spring 1, and the fixing frame 2 is evenly distributed on the leaf spring 1. One end of the screw rod 8 is welded to the outer side of the clamping plate 6, and the other end of the screw rod 8 extends to the inner side of the screw sleeve 9. The outer side of the screw rod 8 is provided with an external thread 1, and the inner side of the screw sleeve 9 is provided with an internal thread 1, and the external thread 1 cooperates with the internal thread 1. The nut 10 is sleeved on the outer side of the bottom end of the U-shaped screw rod 4, and the bottom end of the U-shaped screw rod 4 is provided with an external thread 2, and the inner side of the nut 10 is provided with an internal thread 2, and the external thread 2 cooperates with the internal thread 2.

After the spacing of the plates 6 is adjusted, the top of the nut 9 is flush with the top of the clamping plate 6, and then after the clamping plate 6 is clamped on the bottom of the support frame, the screw sleeve 8 is limited by the bottom of the support frame to prevent the screw sleeve 9 from rotating, thereby effectively preventing the U-shaped screw 4 on both sides of the support frame from moving in the horizontal direction. The wedge block 14 in the slot 13 is inserted into the inner side of the wedge groove 12 on the rotating plate 11 under the elastic force of the spring 15. The inclination angle of the wedge block 14 and the wedge groove 12 is utilized to enable the nut 10 to be smoothly tightened on the bottom of the clamping plate 6 and prevent the rotating plate 11 from rotating in the opposite direction, thereby effectively preventing the nut 10 from loosening, thereby effectively ensuring the installation firmness of the leaf spring 1 and the support frame, preventing loosening, and effectively ensuring the working safety of the leaf spring 1.
