Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1 - 4 shown, a tray-type shock absorber for an automobile suspension includes a shock absorber body 1 and a limit component 4. A limit groove 2 is opened on the upper outer wall of the shock absorber body 1, and an adjustment disc 3 is movably arranged around the limit groove 2. A tray 5 is fixedly installed on the top of the adjustment disc 3. The limit component 4 for limiting the height of the tray 5 is installed at the bottom of the tray 5. The limit component 4 includes an extrusion block 401, a push rod 402, a movable block 403, a positioning rod 404 and a spring 405. The rear end of the extrusion block 401 is fixedly installed with the push rod 402, and the rear end of the push rod 402 is sleeved with the movable block 403. The front end of the movable block 403 is fixed to the adjustment disc 3, and a positioning rod 404 is vertically arranged inside the movable block 403, and a spring 405 is arranged at the top of the positioning rod 404.

[0023] During adjustment, press the extrusion block 401, so that the extrusion block 401 pushes the push rod 402 to insert into the inside of the movable block 403 and jack it up at the same time, so that the end of the movable block 403 breaks away from the groove opened at the bottom right of the limit groove 2, so that the adjustment disc 3 rotates counterclockwise while losing the restraint of the movable block 403 and enters the left side of the limit groove 2, so that the adjustment disc 3 and the tray 5 can adjust the height to prevent the tray 5 from slipping due to vibration.

[0024] As Figure 4 shown, a round hole 6 is arranged in the middle of the tray 5, and the tray 5 is slidably connected to the shock absorber body 1 through the round hole 6.

[0025] Furthermore, a bearing hole 7 is opened at the bottom end of the shock absorber body 1, and a vehicle axle rod 8 is rotatably connected inside the bearing hole 7.

[0026] The bearing hole 7 facilitates the installation and docking of the vehicle axle rod 8 and the shock absorber body 1.

[0027] Furthermore, a lubricating ball 9 is rotatably connected to the top of the automobile shaft 8 , and a ball seat 10 is rotatably connected to the top of the lubricating ball 9 .

[0028] The ball seat 10 reduces the friction between the lubricating ball 9 and the return spring 11 .

[0029] Furthermore, a return spring 11 is fixedly mounted on the top of the ball seat 10 , and an oil groove 12 is provided on the shock absorber body 1 corresponding to the top of the return spring 11 .

[0030] The oil tank 12 is used to store excess lubricating oil therein for later use.

[0031] Furthermore, the lubricating ball 9 is elastically connected to the oil groove 12 via the return spring 11 , and the oil groove 12 is through-connected to the bearing hole 7 .

[0032] The front end of the oil groove 12 is provided with an oil filling hole for adding lubricating oil later.

[0033] Working principle: When using the tray-type shock absorber for automobile suspension, first press the extrusion block 401 during adjustment so that the extrusion block 401 pushes the push rod 402 into the movable block 403 and lifts it up, so that the end of the movable block 403 is separated from the groove opened at the bottom right of the limiting groove 2, so that the adjusting disk 3 loses the restraint of the movable block 403 and rotates counterclockwise and enters the left side of the limiting groove 2, so that the adjusting disk 3 and the tray 5 can adjust the height. When the device is loaded and used, the automobile axle rod 8 arranged in the bearing hole 7 rotates and squeezes the lubricating ball 9, so that the lubricating ball 9 moves up, and the lubricating oil in the oil groove 12 can enter the bearing hole 7 through the gap, and the lubricating ball 9 rotates to evenly apply the lubricating oil on the automobile axle rod 8, thereby achieving the purpose of lubricating the connection of the automobile axle rod 8 installed by the device. This is the working principle of the tray-type shock absorber for automobile suspension.
