Abstract
Between the inner shell cover of connector and supporting pin a buffer component which is parallel to the supporting pin is added, so that when the car is running on the uneven road, the most of external force transferred from supporting pin can be buffered by buffer component so as to produce protection action for elastic body between inner shell cover and outer shell cover. The described elastic body adopts a kind of composite spring made of rubber or polyurethane and steel wire spring. As compared with existent technology its torsional and shear stress and tensile strength can be greatly raised, and its service life also can be prolonged.
Description
Technical field
The present invention relates to a kind of Vibration damping balance device of vehicle vehicle, i.e. vehicle rear suspension back reaction rod band elastomer connector assembly, the particularly wherein elastomer connector of parts and bearing pin assembly.
Background technique
Joint and bearing pin assembly, joint generally comprise interior valve jacket, outer valve jacket and be located in elastomer between valve jacket and the outer valve jacket; The internal chamber wall of interior valve jacket is the cylindrical hole suitable with rest pin, and the rest pin drive fit is arranged in the interior valve jacket; Position corresponding with interior valve jacket both ends of the surface on the rest pin laterally offers annular groove, is embedded with the location snap ring that interior valve jacket can be positioned on the rest pin in this annular groove.The joint of prior art and bearing pin assembly; there is not to be provided with the damping means that is parallel to active force on the rest pin direction; because of vehicle can not always travel on the road of horizontal plane; in case vehicle back and forth is in when height is low on one side on one side; active force will act on a low end by the high end of rest pin; like this will butt joint and bearing pin assembly about cause very big tensile and compressive strength back and forth; be not protected as elastomeric rubber or wire spring; will very fast damage; cause working life short, whole joint and bearing pin assembly will lose vibration damping and balanced action.
And in the prior art, the structure of joint generally comprise interior valve jacket, outer valve jacket and be located in elastomer between valve jacket and the outer valve jacket.Elastomer used in the prior art has two kinds, and a kind of is rubber, injects rubber between valve jacket and the interior valve jacket outside and makes by baking, utilizes the expansion performance of rubber to finish effects such as its vibration damping and balance.Rubber is as playing effects such as tension, resistance to compression, Vibration damping balance, though steadily stationarity is better, telescopic resilience is strong inadequately, in case be subjected to external force than the easy drawing crack of your writing time spent, easily crushed, working life is shorter.Another kind is a wire spring, and the characteristic of utilizing wire spring to stretch replaces rubber to play vibration damping and balanced action processes.Wire spring is as playing effects such as tension, resistance to compression, Vibration damping balance, though elasticity is strong, but it is bad to exist steady stationarity, tension, the shortcoming that compressive strength is low, in case it is easily crooked than the your writing time spent to be subjected to external force, and, exist short problem in working life equally when the characteristic of bending the body that just follows the string after strong coefficient reaches capacity.
Summary of the invention
It is higher to the purpose of this invention is to provide a kind of antitorque shearing stress, and tension pressure is stronger, the improved joint and the bearing pin assembly of longer service life.
Technological scheme of the present invention is such: a kind of improved joint and bearing pin assembly, comprise interior valve jacket, outer valve jacket, rest pin and be located in elastomer between valve jacket and the outer valve jacket, and the inner casing cover is sheathed on outside the rest pin, and rest pin is respectively equipped with interior valve jacket positioning device near the correct position of interior valve jacket both ends of the surface; Valve jacket is along the recessed respectively outer side wall to correspondence of the internal chamber wall at the two ends that wear direction of above-mentioned rest pin in above-mentioned, in above-mentioned, form two toroidal cavities not connecting between the two ends of valve jacket inner chamber and the above-mentioned rest pin, be equipped with the vibration reduction and cushioning parts respectively between these two toroidal cavities interior valve jacket positioning device corresponding with each; The external diameter of valve jacket positioning device is greater than the external diameter of above-mentioned toroidal cavity in above-mentioned.
Above-mentioned vibration reduction and cushioning parts are for opening the elastomer of being located between above-mentioned toroidal cavity bottom and the above-mentioned interior valve jacket positioning device.
Above-mentioned elastomer is a wire spring.
The complex spring of above-mentioned elastomer for making by wire spring and rubber.
The complex spring of above-mentioned elastomer for making by wire spring and polyurethane.
Above-mentioned rest pin laterally offers annular groove respectively near the correct position of valve jacket both ends of the surface in above-mentioned, and above-mentioned interior valve jacket positioning device is the steel card spring that is embedded in this annular groove, and the external diameter of this steel card spring is greater than the external diameter of above-mentioned toroidal cavity.
The valve jacket positioning device is to be fixed on the above-mentioned rest pin respectively near the rigid baffle on the correct position of valve jacket both ends of the surface in above-mentioned in above-mentioned, and the external diameter of this rigid baffle is greater than the external diameter of above-mentioned toroidal cavity.
The complex spring of elastomer in above-mentioned between valve jacket and the above-mentioned outer valve jacket for forming through baking by rubber and wire spring.
The complex spring of elastomer in above-mentioned between valve jacket and the above-mentioned outer valve jacket for forming through baking by polyurethane and wire spring.
The external diameter surface of valve jacket and the inside diameter surface of above-mentioned outer valve jacket are processed with screw thread respectively in above-mentioned.
After adopting such scheme, improved joint of the present invention and bearing pin assembly, when vehicle driving is in out-of-level road, joint and bearing pin assembly are high on one side low on one side, external force inwardly acts on the buffer unit of also directly this being defeated on the corresponding interior valve jacket positioning device in the toroidal cavity of a higher end from the higher end of rest pin, carry out transformation of energy, thereby consumed a part of active force; Remaining a part of active force is pressed to by inner casing collar-shaped cavity bottom on the buffer unit and corresponding interior valve jacket positioning device in the toroidal cavity of a lower end, carries out transformation of energy.Like this, the buffer unit by interior valve jacket two ends balances out most of external force, thereby internally the elastomer between valve jacket and the outer valve jacket plays a protective role.And the elastomer among the present invention between valve jacket and the outer valve jacket has adopted the complex spring of being made up of rubber or polyurethane and wire spring.The present invention has compared with prior art improved antitorque shearing stress and tension pressure greatly, thereby has prolonged its working life.
