TECHNICAL FIELD

[0001] The utility model relates to shock absorber technical field, especially a kind of shock absorber for connecting rod for vehicle. BACKGROUND

[0002] Shock absorber plays a pivotal role in the automobile or motorcycle industry with comprehensive technology. The comfort of the passenger and the wear degree of the whole vehicle machine are inseparable from the performance of the shock absorber. The shock absorption of the whole vehicle depends on the telescopic length of the shock absorber when bearing a certain weight. The greater the telescopic amplitude, the better the shock absorption performance. The currently used shock absorbers include spring shock absorber, hydraulic shock absorber, air bag shock absorber and gas-liquid combined shock absorber.

[0003] The currently disclosed patent CN221138479U discloses a shock absorber multi-link mechanism, which adopts a multi-link structure to transmit the swing of the rear swing arm to the shock absorber. Through the multi-link characteristics, the swing of the rear swing arm is converted into the swing of the shock absorbing rocker to increase the shock absorbing stroke, making the shock absorbing force value change more sensitive and controllable, thereby providing riding comfort. In addition, it can also avoid the phenomenon of easy bottoming of direct suspension, providing comfort while avoiding the safety hazards caused by shock bottoming impact.

[0004] Based on the above search, the shock absorber multi-link mechanism can avoid the phenomenon of easy bottoming of direct suspension, provide comfort while avoiding the safety hazards caused by shock bottoming impact. However, the shock absorber uses a hydraulic cylinder as a buffer during use. Due to the influence of the flow rate of hydraulic oil in the hydraulic cylinder, there is resistance in the telescopic process of the piston rod. The reaction speed of the piston rod is slow during telescopic movement, which cannot effectively dissipate the vibration in time, thereby reducing the shock absorption effect of the whole shock absorber.

[0025] Please refer to Figures 1-4The utility model provides a kind of technical scheme: a kind of vehicle connecting rod shock absorber, including motorcycle wheel 1 steel sheet type damping device, the inside fixed sleeve of motorcycle wheel 1 is connected with rotating shaft 2, the front and rear ends of rotating shaft 2 are all rotationally connected with rotating connecting rod 3, the right end of two rotating connecting rods 3 is all rotationally installed with motorcycle frame 4, steel sheet type damping device includes mounting block 5, support diagonal rod 6, boss 7, semicircular steel sheet 8, two sliding blocks 10 and guide slide bar 12, mounting block 5 is fixedly connected at the top of rotating connecting rod 3, support diagonal rod 6 is rotationally installed in the inside of mounting block 5, boss 7 is rotationally installed in the end of support diagonal rod 6 away from mounting block 5, semicircular steel sheet 8 is fixedly connected on the surface of boss 7, the right end of semicircular steel sheet 8 is equipped with two recesses 9, two sliding blocks 10 are respectively rotationally installed in the inside of two recesses 9, the left side of motorcycle frame 4 is equipped with sliding slot 11, guide slide bar 12 is fixedly connected in the inside of sliding slot 11, guide slide bar 12 is slidably connected in the inside of two sliding blocks 10, the top of two rotating connecting rods 3 is provided with same structure;

[0026] The connecting rod shock absorber is installed on the rear wheel of the motorcycle during use, and when the motorcycle wheel 1 encounters a bumpy road surface during driving, the motorcycle wheel 1 will move up and down. When the motorcycle wheel 1 moves upward, the left end of the two rotating connecting rods 3 can be rotated upward by the rotating shaft 2. The rotating connecting rod 3 rotates upward and drives the mounting block 5 to move obliquely upward. The mounting block 5 moves obliquely upward and drives the support diagonal rod 6 to move obliquely upward. The movement of the support diagonal rod 6 drives the boss 7 to move and press the surface of the semicircular steel sheet 8. Thus, the semicircular steel sheet 8 is deformed by being pressed. The deformation of the semicircular steel sheet 8 drives the sliding blocks 10 at both ends to slide away from each other. The two sliding blocks 10 slide away from each other on the surface of the guide slide bar 12, and the guide slide bar 12 guides and positions the two sliding blocks 10, ensuring the stability of the sliding of the two sliding blocks 10. Thus, the semicircular steel sheet 8 can be deformed smoothly and reset. At this time, the vibration of the motorcycle wheel 1 can be buffered by the two semicircular steel sheets 8. Since the semicircular steel sheet 8 can deform rapidly and recover, the two semicircular steel sheets 8 can effectively dissipate the vibration in time, thereby improving the damping effect of the shock absorber.

[0027] The inside of the sliding block 10 is provided with an annular clamping groove 13. The annular clamping groove 13 is slidably connected with a wear-resistant ball 14. The wear-resistant ball 14 is circularly and equidistantly distributed around the center of the annular clamping groove 13. The surface of the wear-resistant ball 14 is in contact with the surface of the guide slide bar 12.

[0028] When the two sliders 10 slide on the surface of the guide slide rod 12, the slider 10 slides and drives the wear-resistant ball 14 to slide up and down on the surface of the guide slide rod 12 through the annular clamping groove 13. The wear-resistant ball 14 rolls through the friction between the guide slide rod 12. Since the contact area between the wear-resistant ball 14 and the guide slide rod 12 is smaller, the friction of the slider 10 sliding on the surface of the guide slide rod 12 is reduced, the resistance of the slider 10 sliding on the surface of the guide slide rod 12 is reduced, the smoothness of the slider 10 sliding on the surface of the guide slide rod 12 is improved, and the stable sliding of the two sliders 10 on the surface of the guide slide rod 12 is ensured to prevent jamming.
