Abstract
The utility model discloses one to rise type automobile shock inner sleeve, comprise the pipe shaft body of middle part for outwards heaving, pipe shaft body is provided with the endoporus at its two ends through, the outer surface that the middle part of described pipe shaft body is heaved is provided with some restraining grooves, and some restraining grooves axle centered by the shaft axis of described endoporus becomes even circumferential to distribute.The utility model is provided with some restraining grooves at the outer surface that the middle part of pipe shaft body is heaved, and can increase the area of contact of vulcanized rubber and pipe shaft body outer surface, thus strengthens the bonding strength of vulcanized rubber and pipe shaft body.
Description
Technical field
The utility model relates to car shock mitigation system technical field, especially relates to one and to rise type automobile shock inner sleeve.
Background technique
In modern vehicle suspension design, a large amount of rubber bushing etc. that adopts flexibly connects the needs meeting Vehicle damper noise reduction, and the suspension kinematical characteristic required for obtaining.The effect of automobile absorber is the vibrations of attenuate ground to vehicle, ensure the stationarity that vehicle travels and travelling comfort, wherein shock absorbing bushing assembly is important parts, the effect of shock absorbing bushing assembly connects automotive body and vibration damper, buffer function is played to external force simultaneously, shock absorbing bushing assembly comprises damping inner sleeve, connect outer tube and vulcanized rubber, damping inner sleeve is connected with vehicle body, connect outer tube to be connected with the connecting rod of vibration damper, vulcanized rubber is adhered to the outer surface of damping inner sleeve with between the internal surface being connected outer tube, vibration damper is connected with vehicle body and plays flexible buffer effect.Existing one rises type damping inner sleeve, in the middle part of it, outward bulge rises, cause the bonding force of damping inner sleeve and vulcanized rubber uneven, in use, damping inner sleeve easily causes vulcanized rubber to depart from the outer surface of damping inner sleeve with the relative movement being connected outer tube, thus affects the damping effect of shock absorbing bushing assembly.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide one and rises type automobile shock inner sleeve, the outer surface that the middle part of pipe shaft body is heaved is provided with some restraining grooves, the area of contact of vulcanized rubber and pipe shaft body outer surface can be increased, thus strengthen the bonding strength of vulcanized rubber and pipe shaft body.
To achieve these goals, the technological scheme that the utility model adopts is:
One rises type automobile shock inner sleeve, comprise the pipe shaft body of middle part for outwards heaving, pipe shaft body is provided with the endoporus at its two ends through, and the outer surface that the middle part of described pipe shaft body is heaved is provided with some restraining grooves, and some restraining grooves axle centered by the shaft axis of described endoporus becomes even circumferential to distribute.
Wherein, the both ends of the surface of described pipe shaft body are respectively equipped with the colored tooth concentric with described endoporus.Described restraining groove is arranged in vertical, and the groove depth of restraining groove is 1-2 millimeter.
Adopt after technique scheme, the utility model compared to the prior art advantageously:
The type automobile shock inner sleeve that rises described in the utility model, it outwards heaves the restraining groove that place is provided with some vertical settings in the middle part of pipe shaft body, the effect of this restraining groove is when immersing for vulcanized rubber in rubber and thermoplastic molten Blending Processes, increase the area of contact of vulcanized rubber and pipe shaft body outer surface, make the bonding more firm of vulcanized rubber and pipe shaft body, when after vulcanized rubber solidifying, restraining groove also plays radial position-limiting action, during to prevent damping inner sleeve and to be connected the relative movement of outer tube, vulcanized rubber departs from pipe shaft body, and then improve the damping performance of shock absorbing bushing assembly, extend its working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is perspective view of the present utility model.
Fig. 2 of the present utility modelly faces structural representation.
Fig. 3 is sectional structure schematic diagram of the present utility model.
In figure, 1: pipe shaft body; 2: endoporus; 3: restraining groove; 4: flower tooth.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 3:
Automobile shock inner sleeve, it is one of shock absorbing bushing assembly, shock absorbing bushing assembly comprises damping inner sleeve, connects outer tube and vulcanized rubber, damping inner sleeve is connected with vehicle body, connect outer tube to be connected with the connecting rod of vibration damper, vulcanized rubber is adhered to the outer surface of damping inner sleeve with between the internal surface being connected outer tube, to be connected to play flexible buffer effect to vibration damper with vehicle body.Traditional type automobile shock inner sleeve that rises, outwards heave in the middle part of its pipe shaft body 1, pipe shaft body 1 is provided with the endoporus 2 at its two ends through, in use, damping inner sleeve easily causes vulcanized rubber to depart from the outer surface of damping inner sleeve with the relative movement being connected outer tube, thus affects the damping effect of shock absorbing bushing assembly.
The type automobile shock inner sleeve that rises described in the present embodiment, restraining groove 3,12 restraining grooves 3 axle centered by the shaft axis of described endoporus 2 that the outer surface that the middle part of its pipe shaft body 1 is heaved is provided with the angular separation distributions such as 12 becomes even circumferential to distribute.Restraining groove 3 is arranged in vertical, and the groove depth of restraining groove 3 is 1-2 millimeter.The both ends of the surface of pipe shaft body 1 are respectively equipped with the colored tooth 4 concentric with described endoporus 2.
The effect of restraining groove 3 is when immersing for vulcanized rubber in rubber and thermoplastic molten Blending Processes, increase the area of contact of vulcanized rubber and pipe shaft body 1 outer surface, make the bonding more firm of vulcanized rubber and pipe shaft body 1, when after vulcanized rubber solidifying, restraining groove 3 also plays radial position-limiting action, during to prevent damping inner sleeve and to be connected the relative movement of outer tube, vulcanized rubber departs from pipe shaft body 1, and then improves the damping performance of shock absorbing bushing assembly, extends its working life.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
