AI Technical Summary

Technical Problem

In the prior art, when a threaded connection structure is subjected to long-term vibration conditions, the interlocking failure is caused by the loosening of the threaded spring disk. The rotation of the threaded spring disk changes the design height of the spring, resulting in a poor vehicle body posture, and abnormal noise caused by the gnawing of the threads.

Method used

An annular groove is opened on the bottom of the external sleeve spring of the oil storage cylinder and the threaded spring disk, and a damping washer is set. The damping washer is located between the threaded spring disk and the threaded locking ring. It absorbs part of the locking torque through deformation and reacts to the threaded spring disk and the threaded locking ring. The damping washer has elasticity to increase the locking force and compensate for the thread gap.

Benefits of technology

The locking force between the threaded spring disc and the threaded locking ring is improved, which delays thread loosening, prevents thread gnawing and abnormal noise, and adapts to the use requirements of large-load springs.

Abstract

The utility model discloses a spring plate thread interlocking structure capable of improving locking force, which comprises an oil storage barrel, a spring is sleeved outside the oil storage barrel, the oil storage barrel is in threaded connection with a thread spring plate, an annular groove is arranged at the bottom of the thread spring plate, a damping washer is arranged in the annular groove, and a thread locking ring is further in threaded connection outside the oil storage barrel. The damping washer is located between the threaded spring disc and the threaded locking ring, so that the threaded spring disc is not in direct contact with the threaded locking ring, and the damping washer is locked through torque. By arranging the damping gasket, a part of locking torque can be absorbed through deformation and then reacts on the threaded spring disc and the threaded locking ring, so that the locking force between the threaded spring disc and the threaded locking ring is improved, and the looseness of threads is delayed; meanwhile, when a large-load spring is matched, the damping gasket can compensate gaps between threads, thread biting is prevented, and abnormal sound can be effectively prevented.

Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a spring disk thread interlocking structure with improved locking force. Background Art

[0002] Under long-term vibration conditions, the threaded spring disk located in the shock absorber oil reservoir is prone to loosening, resulting in interlocking failure. The rotation of the threaded spring disk changes the design height of the spring, resulting in poor vehicle posture. At the same time, the threaded spring disk is affected by the alternating load of the spring, and the threads bite each other, which is prone to produce abnormal noise.

[0003] New energy vehicles are rapidly developing. Their long-range battery packs and various luxury features make them significantly heavier than traditional vehicles. To support this increased weight, spring stiffness and load requirements have also increased. Consequently, existing threaded interlocking spring discs are insufficient and cannot be reused. Utility Model Content

[0004] The purpose of the utility model is to provide a spring disk thread interlocking structure with improved locking force in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a spring disk threaded interlocking structure for improving the locking force, including an oil storage cylinder, and its innovation lies in: the outside of the oil storage cylinder is sleeved with a spring and a threaded spring disk, an annular groove is provided at the bottom of the threaded spring disk, a damping washer is arranged in the annular groove, and the outside of the oil storage cylinder is also threadedly connected to a threaded locking ring, and the damping washer is located between the threaded spring disk and the threaded locking ring, so that the threaded spring disk and the threaded locking ring are not in direct contact, and the damping washer relies on torque for locking.

[0006] Furthermore, the damping washer has elasticity and absorbs a portion of the locking torque through deformation and then reacts on the threaded spring disk and the threaded locking ring.

[0007] After adopting the above structure, the beneficial effects of the utility model are:

[0008] The utility model provides a damping washer, which can absorb a part of the locking torque through deformation and then react on the threaded spring disk and the threaded locking ring, thereby improving the locking force between the threaded spring disk and the threaded locking ring and delaying the loosening of the thread; at the same time, when matching a large-load spring, the damping washer can compensate for the gap between the threads, prevent the threads from biting, and effectively prevent abnormal noise from occurring. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural diagram of the present utility model.

[0010] Description of reference numerals:

[0011] 1 Oil reservoir, 2 Spring, 3 Threaded spring disc, 4 Damping washer, 5 Threaded locking ring. DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] See Figure 1 A spring disk thread interlocking structure for improving locking force includes an oil storage cylinder 1, an external sleeve spring 2 of the oil storage cylinder 1 and a threaded spring disk 3, an annular groove is provided at the bottom of the threaded spring disk 3, a damping washer 4 is arranged in the annular groove, and the external threaded locking ring 5 is also threadedly connected to the oil storage cylinder 1, and the damping washer 5 is located between the threaded spring disk 3 and the threaded locking ring 5, so that the threaded spring disk 3 and the threaded locking ring 5 are not in direct contact, and the damping washer 4 relies on torque for locking. Specifically, this structure adds a damping washer 4 between the threaded spring disk 3 and the threaded locking ring 5 to replace the original structure in which the threaded spring disk and the threaded locking ring are in direct contact. The added damping washer 4 can absorb a part of the locking torque through deformation and then react to the threaded spring disk and the threaded locking ring, thereby improving the locking force and delaying the loosening of the thread. This structure still retains the advantage of the adjustable spring disk; at the same time, when matching a large-load spring, the damping washer 4 can compensate for the gap between the threads to prevent the threads from biting, which can effectively prevent abnormal noise.

[0015] In this embodiment, the damping washer 5 is elastic and absorbs a portion of the locking torque through deformation and then reacts on the threaded spring disk 3 and the threaded locking ring 5, thereby increasing the locking force and delaying thread loosening.

[0016] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
