Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile guider, especially relates to a wear -resisting type automobile guider. BACKGROUND

[0002] The guider plays a key role in many mechanical devices, and its main function is to guide the movement of components along a specific path to ensure the normal operation of the device. However, in actual use, the guider faces many challenges, among which the wear problem is particularly prominent. For example, in the case of an automobile shock absorber guider, the shock absorber piston rod will frequently reciprocate within the guider during vehicle driving. Due to friction during movement and impact caused by uneven road surface during vehicle driving, the guider is prone to wear. Once the guider is worn, it will cause unstable movement of the piston rod, reduce the performance of the shock absorber, and thus affect the driving comfort and safety of the vehicle.

[0003] The lubrication system of the existing guider is mostly designed with simple oil injection holes or shallow grooves, which can cause insufficient local lubrication and increase the friction coefficient, not only exacerbating wear, but also possibly leading to unstable operation of the guider. Most existing guiders do not have self-repairing function. Once a small wear appears on the surface of the guider, it cannot be automatically repaired. With the accumulation of wear, it will gradually affect the guiding accuracy, cause movement deviation of the piston rod, and thus affect the control stability and comfort of the automobile. Therefore, we propose a wear-resistant automobile guider. UTILITY MODEL CONTENTS

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1 - Appendix Figure 6 A wear-resistant automotive guide includes a guide body 1 and a wear-resistant inner liner 7. The guide body 1 has a cylindrical structure, and its inner diameter is adapted to the piston to ensure a tight fit and smooth sliding. The guide body 1 has slots 2 at both its upper and lower ends. An annular lubrication channel 6 is formed inside the guide body 1, and an oil outlet 13 is formed on the inner wall of the guide body 1, penetrating the wear-resistant inner liner 7. The wear-resistant inner liner 7 is made of tungsten carbide alloy. The annular lubrication channel 6 spirals around the inner wall of the guide body 1 and the wear-resistant inner liner 7, with one end connected to an external lubrication device and the other end closed. An installation groove 11 is formed inside the wear-resistant inner liner 7, and a mounting device is fixed inside the installation groove 11. The device is equipped with self-healing microcapsules 12. The outer shell of the self-healing microcapsules 12 is made of polymer material and contains a repair agent. The upper and lower ends of the guide body 1 are both through the first threaded holes 3 near the edges. The first threaded holes 3 are threaded with fastening bolts 4. The upper surface of the guide body 1 is provided with an oil inlet pipe 5, which is connected to the upper end of the annular lubrication channel 6. The lower end of the annular lubrication channel 6 is closed. The oil outlet hole 13 is connected to the annular lubrication channel 6. The wear-resistant inner liner 7 is snapped into the inside of the guide body 1. The upper and lower ends of the wear-resistant inner liner 7 are both provided with second threaded holes 8. The second threaded holes 8 are connected to a limit cover plate 9 through a limit bolt 10. The limit cover plate 9 is snapped into the inside of the slot 2.

[0024] The slot 2 is used for the installation of the limiting cover plate 9 of the wear-resistant inner liner 7, ensuring the integrity of the entire wear-resistant inner liner 7 and the guide body 1. The limiting cover plate 9 and the wear-resistant inner liner 7 are connected by the limiting bolt 10, which facilitates the replacement of the wear-resistant inner liner 7. The annular lubrication channel 6 and the evenly distributed oil outlet holes 13 can ensure that the lubricating oil is evenly covered on the inner wall of the guide body 1, effectively reducing the coefficient of friction, further reducing wear, and improving the operational stability of the guide. The setting of the self-healing microcapsule 12 enables the guide to automatically repair itself when minor wear occurs, without the need for downtime maintenance, which greatly improves the operating efficiency of the equipment and reduces maintenance costs.

[0025] Specifically, a wear-resistant inner liner 7 made of tungsten carbide alloy is cleverly set on the inner wall of the guide body 1. Tungsten carbide alloy has extremely high hardness and excellent wear resistance, which can effectively resist the friction generated during piston movement. While ensuring excellent wear resistance, it will not affect the overall size and installation compatibility of the guide. Surrounding the inner wall of the guide body 1 and the wear-resistant inner liner 7 is a spiral annular lubrication channel 6. When the external lubrication device injects lubricating oil, it can evenly cover the inner wall and the surface of the wear-resistant inner liner 7 through the oil outlet 13 to form a lubricating film, which greatly reduces the friction coefficient between the piston rod and the guide and reduces wear. In addition, the evenly distributed self-healing microcapsules 12 have a shell made of polymer material and contain a repair agent. Once the wear-resistant inner liner 7 is slightly damaged due to friction, the self-healing microcapsules 12 rupture, release the repair agent, and polymerize under the action of oxygen or moisture to quickly fill the damage, realize the self-repair of the wear-resistant inner liner 7, and continuously maintain the wear resistance of the guide body 1.

[0026] The working principle of this utility model is as follows: This utility model is a wear-resistant automotive guide. First, the wear-resistant inner liner 7 is inserted into the guide body 1. Then, the limiting bolt 10 is tightened into the second threaded hole 8, so that the limiting cover 9 is exactly stuck in the slot 2, forming an integral part with the guide body 1. The wear-resistant guide is installed on the corresponding equipment through the first threaded hole 3 and fastening bolts 4 and other connecting parts to ensure a firm installation. Before the equipment is running, the oil inlet pipe 5 is connected to an external lubrication device. During the operation of the equipment, when the piston moves in the guide body 1, the lubricating oil enters and is evenly distributed along the oil outlet hole 13 on the inner wall of the guide body 1 and the surface of the wear-resistant inner liner 7, forming a lubricating film, which further reduces the friction coefficient between the piston rod and the guide, reducing wear. When the wear-resistant inner liner 7 is slightly damaged due to friction, the self-repairing microcapsule 12 ruptures, releasing a repair agent, which polymerizes under the action of oxygen or moisture, quickly filling the damage, realizing the self-repair of the wear-resistant inner liner 7, and continuously maintaining the wear resistance of the guide body 1.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
