Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber inner core tube technology, and in particular to an automotive shock absorber inner core tube structure with a spiral oil outlet channel. Background Technology

[0002] The shock absorber is the core component of the car suspension system. Its core function is to absorb the vibrations caused by road bumps and suppress the repeated bouncing of the springs, so as to ensure a smooth and comfortable ride. It works by using the principle of damping, which uses the reciprocating motion of the piston in the cylinder to convert the vibration energy into heat energy and dissipate it, thereby reducing the body sway. On bumpy roads, when braking or turning, it can quickly stabilize the body and prevent the tires from leaving the ground, while improving handling and safety.

[0003] The inner core tube of an automotive shock absorber is its core functional component, providing the mounting and working platform for the damping mechanism. It is mostly made of high-strength metal and contains damping oil. It works in conjunction with the piston and piston rod to achieve reciprocating motion. When the vehicle encounters bumps, the piston moves inside the tube, and the damping oil generates resistance through the oil holes, converting vibration energy into heat energy for dissipation. Its precision structure and pressure and wear-resistant properties directly determine the damping effect of the shock absorber, affecting the vehicle's driving stability and handling safety. It is a key component to ensure the normal functioning of the shock absorber.

[0004] Traditional automotive shock absorbers lack efficient heat dissipation methods in their inner core tubes. Under continuous bumpy conditions, the oil temperature rises sharply, causing the oil viscosity to decrease, resulting in weakened damping force, thermal decay, accelerated oil aging, and shortened shock absorber lifespan.

[0005] Therefore, it is necessary to provide an inner core tube structure for automotive shock absorbers with a spiral oil outlet channel to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides an inner core tube structure for automotive shock absorbers with a spiral oil outlet channel, which solves the problem of inefficient heat dissipation in traditional automotive shock absorber inner core tubes, which causes the oil to heat up during continuous bumps, resulting in weakened damping, oil aging, and shortened lifespan.

[0007] To solve the above-mentioned technical problems, the automotive shock absorber inner core tube structure with a spiral oil outlet channel provided by this utility model includes: an inner tube body;

[0008] A threaded cooling groove is formed on the outer surface of the inner tube body near the upper half. A spiral heat dissipation base plate is fixedly connected to the inner surface of the threaded cooling groove. An installation assembly is installed inside the inner tube body near the bottom. A rotating structure is installed below the installation assembly. A spiral flow guide assembly is installed on the outer surface of the rotating structure.

[0009] An outer tube body, which is installed on the outer surface of the inner tube body near the top;

[0010] The rotating structure is a high-sealed bearing, which allows the spiral guide assembly to rotate below the mounting assembly.

[0011] Preferably, the mounting assembly includes a plurality of connecting bolts, a collar, and a mounting ring, wherein the plurality of connecting bolts are used to mount the collar inside the inner tube body, and the mounting ring is used to mount the rotating structure below the collar.

[0012] Preferably, a sealing assembly is provided at the top end of the inner tube body, and a piston structure is provided inside the outer tube body;

[0013] The piston structure passes through the mounting assembly and is inserted into the interior of the inner tube body.

[0014] Preferably, the spiral guide assembly includes a docking ring and a guide impeller, wherein the docking ring is used to mount the guide impeller on the outer surface of the mounting ring.

[0015] Preferably, the threaded cooling groove has a pitch of 5-10 mm and a depth of 2-3 mm, and the spiral heat dissipation substrate is made of aluminum.

[0016] Preferably, the inner tube body includes an outer tube, a filling layer, and an inner tube, wherein the filling layer is located between the inner tube and the outer tube;

[0017] The bottom and top of the inner and outer tubes are sealed.

[0018] Preferably, the filling layer is made of paraffin wax, and the distance between the inner tube and the outer tube is 1.5-3 mm.

[0019] Compared with related technologies, the automotive shock absorber inner core tube structure with a spiral oil outlet channel provided by this utility model has the following beneficial effects:

[0020] This utility model provides an inner core tube structure for an automotive shock absorber with a spiral oil outlet channel. To improve the overall heat dissipation of the automotive shock absorber, a spiral cooling groove is opened on the outer surface of the inner tube body near the upper half, and a spiral heat dissipation base is set inside the spiral cooling groove.
