Description

Technical Field

[0001] The utility model relates to the technical field of suspension shock absorption, and more specifically to an automobile suspension shock absorption mechanism. Background Art

[0002] The automobile suspension shock-absorbing mechanism is a device installed in the automobile suspension system. It is mainly used to reduce the vibration and bumps of the vehicle during driving, provide a more comfortable ride experience and better handling stability. The automobile suspension system is an important component connecting the car body and wheels. It supports the car body, buffers uneven road surfaces and reduces vehicle vibrations. It reduces the shaking and bumps of the car body by absorbing and digesting the impact force and vibration generated when the vehicle is driving.

[0003] The Chinese patent announcement number CN219838402U discloses a suspension shock-absorbing structure for a trailer. When an impact occurs on the road surface, the shock-absorbing bushing connected to the head first buffers the impact, and then the shock-absorbing spring converts the impact into repeated bouncing motion of the spring, and at the same time, the shock absorber refines it to accelerate the attenuation of the spring's natural vibration, and finally the shock-absorbing bushing at the auxiliary workshop is used as the final buffer to transmit it to the frame. The present invention accelerates vibration attenuation, enhances buffer absorption, improves the smoothness and comfort of automobile driving, and by arranging rubber shock-absorbing bushings at each connection to absorb impact, it can reduce the damage to metal structural parts caused by instantaneous impact and increase the service life of the suspension assembly.

[0004] When a car is driving on the road, the suspension shock absorbing mechanism will always cushion the vehicle, so the suspension shock absorber will always vibrate. The shock absorber in the above solution is only connected to the frame with bolts, which is easy to loosen after a long period of vibration. The loose shock absorber will cause the stability of the suspension system to decrease, thereby increasing the frequency of inspection and maintenance.

[0038] The automobile suspension shock absorption mechanism is an important component designed to provide a more comfortable, safe and stable riding and driving experience. It can effectively reduce vibration and bumps during driving and improve the vehicle's handling performance and road adaptability.

[0039] When a car is driving on the road, the suspension shock absorption mechanism will always be in working condition to cushion the vehicle. Traditional shock absorbers are only connected to the frame with bolts. After experiencing long-term vibration, the bolts and nuts are prone to loosening, which can easily cause the shock absorber to loosen. Loose shock absorbers will cause the stability of the suspension system to decrease, making the vehicle more prone to shaking during driving, affecting driving comfort and handling performance, thereby increasing the frequency of inspections and maintenance and increasing the cost of use.

[0040] Based on this, the problem in the related art that the shock absorber is prone to loosening after long-term vibration can be improved. The loose shock absorber will cause the stability of the suspension system to decrease, thereby increasing the frequency of inspection and maintenance.

[0041] See also Figure 1-Figure 5 A shock absorbing mechanism for automobile suspension includes a steering knuckle 1, wherein the outer end of the steering knuckle 1 is rotatably connected with an upper rocker arm 2 and a lower rocker arm 3 respectively, a shock absorbing assembly 4 is arranged at the outer end of the lower rocker arm 3, a connecting assembly 5 is arranged at the top of the shock absorbing assembly 4, a buffer assembly 6 is arranged at the top of the connecting assembly 5, the connecting assembly 5 includes a connecting member 52, a connecting block 54 and a shell 57, a plurality of chute grooves 55 equidistantly distributed in an annular shape are formed at the outer end of the connecting block 54, and a plurality of limiting grooves 56 equidistantly distributed in an annular shape are formed at the outer end of the connecting block 54, a plurality of sliders 58 are fixedly connected to the inner side wall of the shell 57, the sliders 58 are slidably connected to the chute grooves 55, and the limiting grooves 56 are adapted to the sliders 58.

[0042] The outer side of the steering knuckle 1 in this scheme needs to be connected to the wheel hub, and the power transmission shaft of the car can pass through the steering knuckle 1 and be connected to the wheel hub. The upper rocker arm 2 and the lower rocker arm 3 are rotatably connected to the outer end of the steering knuckle 1 respectively, and the other ends of the upper rocker arm 2 and the lower rocker arm 3 are rotatably connected to the frame. When the wheel hub connected to the steering knuckle 1 moves up and down, it will drive the upper rocker arm 2 and the lower rocker arm 3 to rotate up and down. At this time, the shock absorbing assembly 4 connected to the lower rocker arm 3 will be compressed, thereby achieving buffering. The shock absorbing assembly 4 is connected to the buffer assembly 6 through the connecting assembly 5, and the buffer assembly 6 is connected to the frame through the stud. The top of the shock absorber 43 is rotatably connected to the connecting piece 2 52 through bolts and nuts. When the shock absorbing assembly 4 vibrates, the slider 58 is stuck by the limiting groove 56, thereby preventing the shell 57 and the mounting block 51 from rotating relative to each other, reducing the torque applied to the bolts and nuts, reducing the probability of loosening, and reducing the frequency of inspection and maintenance.

[0043] Optionally, in some embodiments, see Figure 3 and Figure 5 The connecting assembly 5 also includes a mounting block 51, which is fixedly connected to the bottom end of the connecting block 54, and the bottom end of the mounting block 51 is fixedly connected to the connecting member 2 52.

[0044] A telescopic spring 59 is disposed inside the shell 57 . The top end of the telescopic spring 59 is fixedly connected to the inner wall of the shell 57 . The bottom end of the telescopic spring 59 is fixedly connected to a movable plate 510 . The movable plate 510 abuts against the connecting block 54 .

[0045] The movable plate 510 is slidably connected to the inner wall of the shell 57, and the outer ends of the mounting block 51 and the shell 57 are fixedly connected with a plurality of connecting members 53, and the shell 57 and the mounting block 51 are connected by bolts.

[0046] The mounting block 51 is fixed with a second connector 52 at the top and bottom, and the second connector 52 is used to connect with the shock absorbing assembly 4, and the slide groove 55 is used to connect with the shell 57. The shell 57 is fixedly connected with the mounting seat 61, and can be welded or the like. A plurality of annularly distributed sliders 58 are fixedly connected to the inner bottom of the shell 57, and a plurality of slide grooves 55 are provided at the outer end of the connecting block 54, and a limiting groove 56 is provided between every two slide grooves 55. The plurality of slide grooves 55 and the limiting grooves 56 are interconnected. At the same time, a telescopic spring 59 and a movable plate 510 are provided inside the shell 57. The movable plate 510 is slidably connected with the inner wall of the shell 57. When installing, the shell 57 needs to be firstly installed. The slider 58 on 7 is aligned with the slide groove 55 on the connecting block 54 and slides downward, and then the shell 57 is rotated so that the slider 58 slides into the limiting groove 56 and is stuck, and then the force of the telescopic spring 59 will make the movable plate 510 push the connecting block 54 so that the slider 58 is always stuck, so that it is convenient to use bolts and nuts to connect the shell 57 and the mounting block 51. When the shock absorbing component 4 buffers the vibration, the shell 57 and the mounting block 51 are prevented from rotating relative to each other, reducing the torsion applied to the bolts and nuts. It is worth mentioning that when installing, the nut located between the two connecting parts 53 needs to be screwed upward first so that it can push the shell 57 upward, and finally the nut on the top is installed.

[0047] Optionally, in some embodiments, see Figure 2 and Figure 4 The shock absorbing assembly 4 includes a piston rod 42, one end of the piston rod 42 is fixedly connected to a separation plate 41, the outer end of the separation plate 41 is fixedly connected to a connecting piece 46, and the connecting piece 46 is rotatably connected to the lower rocker arm 3.

[0048] A shock absorber 43 is provided at the outer end of the piston rod 42 , and a coil spring 45 is sleeved on the outer end of the shock absorber 43 . The top end of the shock absorber 43 is rotatably connected to the second connecting member 52 .

[0049] The shock absorbing assembly 4 also includes an adjusting ring 44. The outer end of the shock absorber 43 is engraved with a thread. The adjusting ring 44 is threadedly connected to the shock absorber 43. The coil spring 45 is located between the adjusting ring 44 and the separation plate 41, and the two ends of the coil spring 45 are respectively in contact with the adjusting ring 44 and the separation plate 41.

[0050] The shock absorbing assembly 4 in this scheme mainly plays a buffering role in the suspension system. The main principle of the shock absorbing assembly 4 is to buffer the vibration of the vehicle suspension system through damping force. When the vehicle passes through an uneven road surface or is impacted, the shock absorber 43 will slow down the movement of the vehicle body by generating a damping force. The shock absorbing assembly 4 mainly includes a piston rod 42, a coil spring 45 and a shock absorber 43. The interior of the shock absorber 43 is hydraulic oil. A piston is provided at the top of the piston rod 42. When the piston rod 42 pushes the piston to squeeze the hydraulic oil, a damping force is generated through the internal damping device and the coil spring 4 5 cooperates with the action force of the shock absorber 43, thereby reducing the movement and vibration of the vehicle body. At the same time, a separation plate 41 is fixed to the outer end of the piston rod 42, and an adjusting ring 44 is threadedly connected to the outer end of the shock absorber 43. The coil spring 45 sleeved on the outer end of the shock absorber 43 will be clamped by the adjusting ring 44 and the separation plate 41. When the adjusting ring 44 is rotated, the stroke of the coil spring 45 will be changed, and the compression degree of the coil spring 45 will be adjusted, thereby improving the convenience of adjusting the softness and hardness of the shock absorber. A connecting piece 46 is fixedly connected to the bottom end of the separation plate 41, and it can be rotatably installed on the lower rocker arm 3 through the connecting piece 46.

[0051] Optionally, in some embodiments, see Figure 2 and Figure 5 The buffer assembly 6 includes a mounting seat 61, a buffer block 1 62 is fixedly connected to the top of the mounting seat 61, and a plurality of buffer blocks 2 63 are fixedly connected to the top of the mounting seat 61. The buffer block 1 62 and the buffer block 2 63 are both made of rubber material, and the bottom end of the mounting seat 61 is fixedly connected to the shell 57.

[0052] A buffer block 62 and a plurality of buffer blocks 63 are respectively installed on the top of the mounting seat 61 in the present embodiment. The buffer block 62 and the buffer block 63 are made of rubber material. When the mounting seat 61 is connected to the frame through studs, the buffer block 62 and the buffer block 63 will be located therebetween to play a buffering role.

[0053] Working principle: When the scheme is working, when the wheel hub connected to the steering knuckle 1 moves up and down, it will drive the upper rocker arm 2 and the lower rocker arm 3 to rotate up and down. At this time, the shock absorbing assembly 4 connected to the lower rocker arm 3 will be compressed, thereby achieving buffering. The main principle of the shock absorbing assembly 4 is to buffer the vibration of the vehicle suspension system through damping force. The outer end of the shock absorber 43 is threadedly connected with an adjusting ring 44. When the adjusting ring 44 is rotated, the stroke of the coil spring 45 will be changed, and the compression degree of the coil spring 45 will be adjusted. The shock absorbing assembly 4 is connected to the buffer assembly 6 through the connecting assembly 5, and the buffer assembly 6 is connected to the frame through the stud. When the mounting seat 61 is connected to the frame through the stud, the buffer block 1 62 and the buffer block 2 63 made of rubber material will be located therebetween to play a buffering role. When the shock absorbing assembly 4 performs buffering, the slider 58 is stuck by the limiting groove 56, thereby preventing the shell 57 and the mounting block 51 from rotating relative to each other, reducing the torque applied to the bolts and nuts, and reducing the probability of loosening.

[0054] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
