Description

Technical Field

[0001] The utility model relates to the technical field of torsion rubber cores, in particular to a high-strength torsion rubber core. Background Art

[0002] The torsion rubber core is the core component of the suspension system and one of the key components in the automobile driving system. The quality of the torsion rubber core directly affects the comfort of the ride and the safety of driving. The shock-absorbing and buffering effect of the existing torsion rubber core center shaft is insufficient, which can easily lead to intensified collisions between the torsion bar and the rubber core shaft during use, thereby causing easy wear. If it is not replaced for a long time, there will be a risk that the torsion bar and the rubber core shaft will not work. Therefore, the risk factor of use is high, which will affect the normal use of the torsion rubber core when it is subjected to greater pressure.

[0003] For this reason, we propose a high-strength torsion rubber core to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are: through the setting of the buffer component, the torque generated by the main core shaft can be subjected to the first-level shock absorption and buffering, and through the interaction force between the hollow rubber and the soft rubber, the torque can be subjected to the second to third-level shock absorption and buffering, and through the cooperation of the sealing ring, the protective cover and the protective cover, the rubber core can be better protected, which solves the problem that the shock absorption and buffering effect of the central axis of the torque rubber core is insufficient, which easily leads to the intensified collision between the torsion rod and the rubber core shaft during use, thereby causing easy wear. Once they are not replaced for a long time, there will be a risk that the torsion rod and the rubber core shaft will not work. Therefore, the risk factor of use is high, which causes the torque rubber core to be affected in its normal use when it is subjected to greater pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. Specifically, the upper and lower ends of the buffer assembly 4 are respectively provided with a first buffer plate 409 and a second buffer plate 410, and two ends of the top surface of the first buffer plate 409 are respectively fixed with a total of two first cylinders 401.

[0027] One end of two second connecting rods 405 is hinged to the two main connecting rod bases 408 , respectively, and one end of two first connecting rods 404 is hinged to the two auxiliary connecting rod bases 411 , respectively.

[0028] The two second connecting rods 405 are respectively hinged to the middle parts of two connecting blocks 406 , and the middle parts of the two connecting blocks 406 are respectively hinged to one end of the two first connecting rods 404 away from the second buffer plate 410 .

[0029] The two ends of the connecting spring 407 are fixedly connected to the adjacent side walls of the two connecting blocks 406, and one end of a total of two cylindrical springs 403 are fixedly connected to the bottom of the two first cylinders 401 respectively, and the other ends of the two cylindrical springs 403 are fixedly connected to the top of the second cylinder 402 respectively.

[0031] Example 3

[0032] Reference Figure 1-3 , which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, the mounting hole 102 on the connector 101 is installed on the suspension system. When the two connectors 101 receive torsion, the torsion is transmitted to the main spindle 1.

Under the action of the connecting spring 407, the first connecting rod 404 and the second connecting rod 405 reciprocate left and right. The connecting spring 407 and the cylindrical spring 403 cooperate with each other to gradually start buffering and shock absorption. As the buffer component 4 buffers and absorbs shock, the buffer component 4 transmits the external force to the upper and lower ends of the hollow rubber 2. Because the hollow rubber 2 is fixedly sleeved by the soft rubber 5, the hollow rubber 2 and the soft rubber 5 compress and restrain the force generated by the buffer component 4, and finally the torsion at the main core shaft 1 is buffered and shock absorbed.
