Summary of the invention
The purpose of this utility model is to provide the automobile rubber shock-absorbing structure that a kind of freedom shape is large, have good damping effect, can not six to rotating, do not have the damping capacity of appropriateness and not having the technical matters of various performances such as damping, buffering, sound insulation with the damper element solving prior art.
The utility model adopts following technical scheme: a kind of automobile rubber shock-absorbing structure, it comprises for being fixed on seal cover cap above car floor and for being fixed on the elastic bag below car floor, the inner chamber of described seal cover cap and the inner space of elastic bag, described seal cover cap is connected with the breather line with seal cover cap inner space, the bottom of described elastic bag is provided with mounting seat, mounting seat is connected with L shape connecting lever, this L shape connecting lever has a vertical section and a horizontal segment, the end of the vertical section of L shape connecting lever is fixedly connected with mounting seat, the end of L shape connecting lever horizontal segment is for being hinged on the fixed position of automobile body, described mounting seat is hinged with horizontally disposed connecting rod, the other end of this connecting rod is for being hinged on automobile body.
Described automobile rubber shock-absorbing structure also comprises the connecting element for being fixed on car floor, and this connecting element is the inner space of the hollow structure with inner chamber, described breather line and connecting element, described connecting element offers admission port and exhausr port.
Described elastic bag is made up of elastomeric material.
The beneficial effects of the utility model are: the utility model is filled with pressurized air by breather line in elastic bag, the pressure of elastic bag can regulate with the size of load, the load of shock-damping structure and rigidity is made to reach an Appropriate, little to make the shock-damping structure natural frequency of vibration change.By the height of the charge air also adjustable railway carriage of adjustable elastic air bag, make it loading, unloading goods convenient, firm banking due to elastic bag is movably arranged on automobile body by L shape connecting lever and connecting rod, and therefore elastic bag is all in rotary moving in all directions.The utility model has the following advantages: (1) freedom shape is larger; (2) can rotate up in X, Y, Z side, there are six direction actions of the spring; (3) there is the damping capacity of appropriateness, can be used in the scope of low frequency ~ high frequency; (4) there is various performances such as damping, buffering, sound insulation simultaneously; (5) shock stiffness is greater than dynamic stiffness, and dynamic stiffness is greater than Static stiffness, is conducive to reducing blastic deformation and dynamic deformation.
Further, car floor arrange the connecting element with hollow structure, be conducive on the one hand connecting L shape connecting lever, on the other hand admission port and exhausr port be set on connecting element respectively, be conducive to inflating in elastic bag.
Further, the elastic bag elasticity adopting elastomeric material to make is larger, and not easily aging, and service life is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of embodiment of the utility model as shown in Figure 1, the automobile rubber shock-absorbing structure of the present embodiment comprises for being fixed on seal cover cap 2 above car floor and for being fixed on the elastic bag 1 be made up of elastomeric material below car floor, the inner chamber of seal cover cap 2 and the inner space of elastic bag 1, seal cover cap 2 is connected with the breather line 4 with seal cover cap inner space, the bottom of described elastic bag 1 is provided with mounting seat 3, mounting seat 3 is connected with L shape connecting lever 6, this L shape connecting lever 6 has a vertical section and a horizontal segment, the end of the vertical section of L shape connecting lever is fixedly connected with mounting seat 3, the end of L shape connecting lever horizontal segment is for being hinged on the fixed position of automobile body, mounting seat 3 is hinged with horizontally disposed connecting rod 5, the other end of this connecting rod 5 is for being hinged on automobile body.The automobile rubber shock-absorbing structure of the present embodiment also comprises the connecting element 7 for being fixed on car floor, this connecting element 7 is for having the hollow structure of inner chamber, described breather line 4 and the inner space of connecting element 7, described connecting element 7 offers admission port 72 and exhausr port 71.The connecting element of hollow structure, is conducive on the one hand connecting L shape connecting lever, arranges admission port and exhausr port respectively on the other hand, be conducive to inflating in rubber pneumatic bag on connecting element.
