Description

TECHNICAL FIELD

[0001] The utility model relates to air suspension technical field especially relates to an air suspension structure of intelligent driving vehicle convenient to install. BACKGROUND

[0002] In the rapid development of today's automobile industry, intelligent vehicles have become the focus of attention. As an advanced automotive technology, air suspension has been widely used in intelligent vehicles. Through close cooperation with various sensors of intelligent vehicles, air suspension can realize many powerful features. First, it can adjust the hardness and height of the suspension in real time according to the road conditions of the vehicle. When the intelligent vehicle is driving on a flat highway, the sensor detects that the road condition is good, and the air suspension will automatically lower the height to reduce air resistance and improve the driving stability and fuel economy of the vehicle. When the vehicle is driving on a rugged mountain road or a bumpy road, the sensor quickly senses the change in road conditions, and the air suspension will raise the vehicle body to increase the ground clearance and ensure that the vehicle can smoothly pass through complex terrain, while also protecting the vehicle chassis from damage. Second, the air suspension combined with the speed sensor of the intelligent vehicle can dynamically adjust the characteristics of the suspension according to the vehicle speed. When driving at high speed, the air suspension will automatically harden to provide better support and prevent the vehicle from tilting and shaking at high speed, improving safety. When driving at low speed or in a parked state, the suspension will become soft to provide a more comfortable driving experience for passengers

[0003] However, during the installation of air suspension, especially when installing shock absorbers, some problems often occur. Among them, the deflection of the shock absorber during installation is a prominent problem. Due to the high installation precision requirement, it is easy to cause the installation angle deviation of the shock absorber during installation. When performing assembly operations, if the installer fails to strictly follow the standard procedures or is disturbed by external factors during installation, it may cause the angle of the shock absorber installed on the air suspension to deviate. This installation angle deviation will have a series of serious consequences. First, it will affect the overall performance of the air suspension system. The role of the shock absorber is to absorb and buffer the vibration and impact during vehicle driving. If the installation angle is incorrect, the working efficiency of the shock absorber will be greatly reduced. It cannot effectively play its shock-absorbing function, causing the vehicle to vibrate more during driving, not only reducing the comfort of the ride, but also causing additional burden to other parts of the vehicle, accelerating the wear and damage of the parts. Based on the above points, the skilled person in the art proposes an air suspension structure of intelligent driving vehicle convenient to install. SUMMARY

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] REFERENCE Figures 1-5The utility model provides an embodiment of an air suspension structure for an intelligent driving vehicle that is easy to install, comprising a crossbeam 1, with U-shaped fixed fork arms 4 bolted to both sides of the crossbeam 1, guide walls 2 fixed to both sides of the crossbeam 1 through the U-shaped fixed fork arms 4, air springs 3 bolted to the rear ends of the upper side walls of the two guide walls 2, adjustment brackets 5 bolted to the front ends of the two guide walls 2, shock absorbers 6 bolted to the inner sides of the two U-shaped fixed fork arms 4, the other ends of the shock absorbers 6 fixedly connected to the limiting frame 8, and an oil storage fixing piece 7 bolted to the top of the adjustment bracket 5. The oil storage fixing part 7 includes an external threaded tube 71, and a fixing nut 72 is threadedly connected to the outer wall of the external threaded tube 71. The external threaded tube 71 is threadedly connected to the top of the adjusting bracket 5. The inner end of the external threaded tube 71 is arranged inside the top of the shock absorber 6. The interior of the external threaded tube 71 is fixedly connected to an internal threaded tube 77, and the other end of the internal threaded tube 77 is threadedly connected to a fastening screw 73. An extrusion protrusion 710 is fixedly connected to the outer wall of the fastening screw 73. A limiting plate 74 is threadedly connected to the outer wall of the extrusion protrusion 710. The limiting plate 74 is used in conjunction with the limiting frame 8.

[0030] The inner wall of the limiting plate 74 is fixedly connected to the oil storage sleeve limiting plate 79, and the outer wall of the oil storage sleeve limiting plate 79 is clamped with an elastic oil storage sleeve 75. In the process of screwing the fastening screw 73, the extrusion protrusion 710 moves inward, and the top interior of the shock absorber 6 is funnel-shaped. As the extrusion protrusion 710 continues to move, the internal distance between the extrusion protrusion 710 and the top of the shock absorber 6 gradually decreases, thereby continuously squeezing the elastic oil storage sleeve 75, and the fastening screw 73 is tightened to the shock absorber 6 by squeezing the elastic oil storage sleeve 75. Since the elastic oil storage sleeve 75 is arranged between the shock absorber 6 and the extrusion protrusion 710, the elastic characteristics of the elastic oil storage sleeve 75 avoid the abnormal noise caused by the friction between the extrusion protrusion 710 and the shock absorber 6 due to the rigid contact between the extrusion protrusion 710 and the shock absorber 6.

[0031] The elastic oil storage sleeve 75 is a hollow double-layer structure with lubricating oil stored inside. The lubricating oil reduces the friction between the elastic oil storage sleeve 75 and the shock absorber 6. The inner side of the internal threaded tube 77 is fixedly connected with an elastic sleeve limiting tube 76. The elastic sleeve limiting tube 76 abuts against the outer end of the elastic oil storage sleeve 75. The elastic sleeve limiting tube 76 prevents the elastic oil storage sleeve 75 from sliding down together during the process of twisting the fastening screw 73, resulting in the displacement of the elastic oil storage sleeve 75. A number of oil outlet seals 78 distributed in a circular array are provided on the outer wall. When the extrusion protrusion 710 squeezes the elastic oil storage sleeve 75, the lubricating oil stored inside the elastic oil storage sleeve 75 continuously seeps out from the oil outlet seal 78, thereby achieving self-lubrication of the elastic oil storage sleeve 75 and the shock absorber 6. Finally, the fastening screw 73 is continuously screwed in to separate the fastening screw 73 from the limit plate 74. After the limit plate 74 is separated, it can be removed from the shock absorber 6.

[0032] Working principle: when installing the shock absorber 6, first put the outer threaded pipe 71 on the adjusting bracket 5, then use the fixing nut 72 to fix the outer threaded pipe 71 on the adjusting bracket 5, then put the shock absorber 6 into the inner end of the outer threaded pipe 71, and thread the fastening screw 73 inside the inner threaded pipe 77, when fitting, the limiting plate 74 is put into the limiting frame 8, and the limiting plate 74 is used to prevent the shock absorber 6 from rotating, thereby limiting the shock absorber 6, avoiding the situation that the shock absorber 6 cannot be installed smoothly due to the deflection of the shock absorber 6 when installing the other end of the shock absorber 6 subsequently, greatly improving the convenience of subsequent installation of the shock absorber 6, during the process of tightening the fastening screw 73, the extrusion protrusion 710 moves inward, and the top end of the shock absorber 6 is funnel-shaped, as the extrusion protrusion 710 continuously moves, the distance between the extrusion protrusion 710 and the top end of the shock absorber 6 gradually decreases, thereby continuously extruding the elastic oil storage sleeve 75, and the fastening screw 73 is fastened to the shock absorber 6 through the extrusion of the elastic oil storage sleeve 75, and because the elastic oil storage sleeve 75 is arranged between the shock absorber 6 and the extrusion protrusion 710, the elastic characteristics of the elastic oil storage sleeve 75 avoid the frictional noise generated by the friction between the extrusion protrusion 710 and the shock absorber 6 caused by the rigid contact between the extrusion protrusion 710 and the shock absorber 6, and when the extrusion protrusion 710 extrudes the elastic oil storage sleeve 75, the lubricating oil stored in the elastic oil storage sleeve 75 continuously seeps out of the oil outlet seal 78, thereby realizing the self-lubricating effect of the elastic oil storage sleeve 75 and the shock absorber 6, and finally continuously screwing in the fastening screw 73 makes the fastening screw 73 separate from the limiting plate 74, and after the limiting plate 74 is separated, it can be taken out from the shock absorber 6.

[0033] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions described in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, shall be included in the protection scope of the present application.
