High-strength stainless steel spring

Abstract

The utility model provides a high-strength stainless steel spring, which relates to the field of springs and comprises a first movable ring, a second movable ring and a connecting component. By arranging the first spring and the second spring with different rigidities, when the device is installed between two movable parts, the two first movable rings get close to each other due to relative displacement between the two movable parts, and in the process, the two first movable rings are separated from each other. The relative displacement between the two movable parts can preferentially extrude a first spring located between a first connecting block and a second connecting block until a first movable ring and a second movable ring are attached, the first spring cannot be further compressed, and then the displacement between the two movable parts can enable a second spring with higher rigidity to be compressed. Therefore, when the damping device is mostly used as a vehicle damping part, the comfort of a vehicle in the low-speed running process is effectively improved, and meanwhile the stability of the vehicle is improved when the vehicle runs at a high speed.

Description

Technical Field

[0001] The utility model belongs to the technical field of springs, in particular to a high-strength stainless steel spring. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed.

[0003] Springs are often used as components in automobile shock absorbers. The continuous contraction and recovery of the springs can absorb impacts during driving. However, most of the existing automobile springs are difficult to adjust according to different vehicle usage scenarios. When the spring stiffness is small, although it can improve the comfort of the vehicle when driving at low speeds, it is easy to cause the vehicle to tilt when the vehicle is driving at high speeds, affecting safety at high speeds. When the spring height is large, although it can improve the stability of the vehicle's driving, it will cause the ride comfort of the vehicle at low speeds to decrease.

[0004] In summary, the utility model provides a high-strength stainless steel spring to solve the above problems. Utility Model Content

[0007] Wherein, two ends of the first spring respectively abut against opposite sides of the first connecting block and the second connecting block, and two ends of the second spring respectively abut against opposite sides of the two second movable rings.

[0008] Among them, a pair of first sliding blocks are symmetrically arranged on the inner side of the movable groove, and a pair of first sliding grooves are symmetrically arranged on the outer surface of the sleeve. The pair of first sliding blocks are respectively inserted into the pair of first sliding grooves, and the first sliding blocks are slidably connected to the first sliding grooves.

[0009] Among them, a pair of second sliding blocks are respectively arranged at the two ends of the inner side of the sleeve, and two second sliding grooves are symmetrically arranged on the surfaces of the two telescopic rods. The two pairs of second sliding blocks are respectively inserted into the two pairs of second sliding grooves, and the second sliding blocks are slidably connected with the second sliding grooves.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model sets a first spring and a second spring with different stiffnesses. When the utility model is installed between two movable parts, the relative displacement between the two movable parts will cause the two first movable rings to approach each other. In this process, the relative displacement between the two movable parts will preferentially squeeze the first spring located between the first connecting block and the second connecting block until the first movable ring and the second movable ring are fitted together and the first spring cannot be further compressed. After that, the displacement between the two movable parts will compress the second spring with higher stiffness. Therefore, when the utility model is used as a vehicle shock-absorbing component, the comfort of the vehicle during low-speed driving is effectively improved, and the stability of the vehicle when the vehicle is driving at high speed is improved.
