The specific working process is as follows:
after the shock absorber is installed on a suspension system of a new energy automobile, the shock absorber has different shock absorption effects under different states of the automobile, because the automobile usually runs horizontally on a highway, the automobile is easy to jolt due to uneven road conditions under the working state, the comfort level of passengers in the automobile is influenced, at the moment, the vertical shock absorption tube 2 group elastically stretches and contracts to different degrees due to the vibration force, the vibration force borne by the suspension system is balanced, the influence of the vibration force on the suspension system is reduced, the jolting feeling borne by the passengers in the automobile is further reduced, the horizontal shock absorption tube 3 only plays a role of connection under the general condition, the buffer shock absorption work is not carried out, only when the automobile body is impacted or rear-end collision happens, the automobile body can bear the impact force in the horizontal direction, at the moment, the horizontal shock absorption tube 3 elastically stretches and contracts, the influence of the impact force is reduced, and the device and the passengers in the automobile are protected, compare with general automobile shock absorber ware, the device's every shock attenuation pipe elastic strength is less, also more sensitive to the reaction of vibrations, and the shock resistance that this bumper shock absorber can be guaranteed in the design of multiunit shock attenuation pipe is high, consequently better to new energy automobile's shock attenuation effect.
When the automobile is running, the automobile is very easily subjected to vertical vibration force due to road surface, so that the vertical shock absorption pipe 2 always performs shock absorption work, the service life of the vertical shock absorption pipe 2 is short, the replacement frequency is high, at the moment, the fixing buckle 7 is rotated, the inner wall of the clamping plate 73 is separated from clamping connection with the inner cavity of the outer disc shell 12, after the fixing buckle 7 is taken out, the thread clamp shells 51 on the two sides lose clamping connection effect, a user slides the thread clamp shells 51 anticlockwise through the external shifting head 52, the thread connection effect between the thread clamp shells 51 and the outer surface of the vertical shock absorption pipe 2 is relieved, after the vertical shock absorption pipe 2 is taken out, the replacement work can be performed, after the replacement, the thread clamp shells 51 on the two sides are combined through the external shifting head 52 and clamped with the vertical shock absorption pipe 2, the fixing buckle 7 is clamped in the fixing port 4, the fixing effect of the middle part of the vertical shock absorption pipe 2 is realized, and the automobile is often subjected to vertical vibration force, if only fix vertical shock tube 2 in the inner chamber of outer disc shell 12 through threaded connection, under the effect of shock force, the outer surface of vertical shock tube 2 can take place the friction and strike with the thread groove of screw thread clamp shell 51 inner wall, and then with the thread groove wearing and tearing of screw thread clamp shell 51, seriously influences fixed effect.
In reality, when the horizontal impact force of the automobile is often a large force, such as an automobile accident, and the like, it is difficult to ensure the damping effect only by using a single horizontal damping tube 3, and the damping effect may be poor, so that the central damping group 6 is used to enhance the damping effect in the horizontal direction, and when the automobile is subjected to the horizontal impact force, the impact force is often a single acting force in the single direction rather than a plurality of acting forces in the intersecting direction, at this time, the horizontal damping tube 3 is elastically contracted, when the horizontal damping tube 3 partially damps the impact force, the push head 61 absorbs the unbuffered impact force, slides inwards along the inner cavity of the damping spherical shell 11, rolls downwards along the outer surface of the rotating plate 63 through the external rotating wheel 62, at this time, the rotating plate 63 rotates clockwise under the extrusion action of the external rotating wheel 62, the thread spring 64 is extruded, and during the contraction of the thread spring 64, the rotating plates 63 on the two sides have the same elasticity, and through the conduction effect, each threaded spring 64 buffers the impact force to different degrees, so that the damping effect of the whole central damping group 6 is effectively improved.
