Abstract
The utility model relates to an automobile shock absorber which comprises a casing pipe and a bushing which is arranged in the casing pipe and is in interference fit with the casing pipe. The bushing contains an inner pipe and a vulcanized rubber layer arranged on the outer surface of the inner pipe. The outer surface of the vulcanized rubber layer is provided with an annular bulge. The inner wall of the casing pipe is provided with an annular groove which can be installed corresponding to the annular bulge. Several grooves are also axially arranged in the annular groove.
Description
Technical field
The utility model belongs to vibration damper field, refers to especially a kind of automobile absorber.
Background technique
In vehicle traveling process, particularly suspension system is subject to the impacts such as road surface and produces vibration, in order to overcome the vibrations in running process, improves comfort property, in existing automobile, is widely used vibration damper in suspension system.The vibration damper of existing automotive field is with hydraulic damper, its working principle is when between vehicle body and vehicle bridge during vibrated generation relative movement, piston in vibration damper is by moving up and down, damping oil in vibration damper chamber is flowing in another chamber from chamber through hole repeatedly just, now, by the friction between hole wall and fluid and the intermolecular friction of fluid, vibration is formed to damping force, thereby realize damping object.
When carrying out the installation of vibration damper, the same vehicle body of top piston bar (vehicle frame) of vibration damper connects, and the liquid storage cylinder bottom of vibration damper is connected on suspension system.In order to prevent the destruction of vibrations to liquid storage cylinder bottom, the existing method solving is on connecting bolt, to install lining additional to reach the effect of secondary shock-absorbing.
The bottom of existing automobile absorber comprises in sleeve pipe, sleeve pipe and is provided with lining, and lining is mainly by inner tube and the rubber layer on inner tube outer surface, and inner tube and rubber layer sulfuration are fixing, and lining is connected in sleeve pipe by rubber layer interference.
In said structure, internal surface of casing and rubber layer outer surface are plane, and the dial-out power of lining in sleeve pipe is too small, and lining is easily deviate from sleeve pipe.In order to address this problem, notice of authorization number is for CN202274034U proposes to be provided with some convex tendons at the outer surface of vulcanized rubber floor, is provided with the annular groove of some energy and the corresponding installation of above-mentioned convex tendon on the inwall of sleeve pipe.Further be improved to, the convex tendon cross section at vulcanized rubber layer two ends is triangle, and the convex tendon cross section at vulcanized rubber layer middle part is square.By this technological scheme, well solved lining and from sleeve pipe, deviate from problem, but this technological scheme also causes assembling difficulty, and when assembling, easily cause the damage of rubber layer.
Vibration damper in use, although rubber layer is that interference is connected with sleeve pipe, because the intensity of this two material is different, cannot avoid in use there will be the problem that relatively rotates of lining and sleeve pipe.
Model utility content
In order to overcome lining, in sleeve pipe, deviate from and the relatively rotate problem of lining in sleeve pipe, also comprise the assembly technology of simplifying between lining and sleeve pipe and reduce assembling difficulty, a kind of automobile absorber technological scheme is provided.
The utility model is achieved through the following technical solutions:
A kind of automobile absorber, comprise sleeve pipe and be placed in sleeve pipe and with the lining of its interference fit, described lining comprises inner tube and is placed in the vulcanized rubber layer on inner tube outer surface, the outer surface of described vulcanized rubber layer is provided with ring projection, on the inwall of described sleeve pipe, be provided with can with the annular groove of the corresponding installation of ring projection; In described annular groove, be also axially provided with some grooves.
The outer surface of described inner tube is cylindrical or cydariform.
The radial cross-section of described groove is square, trapezoidal, triangle or arc.
The center line of described groove is for being parallel to sleeve pipe center line.
The center line of described groove is non-rectilinear.
The utility model beneficial effect is compared with the existing technology:
Because rubber layer only has a ring projection, when assembling, be very easy to install.On the other hand, in interference when assembling of carrying out lining and sleeve pipe, rubber layer can be pressed in the groove of bushing pipe inwall, increases between sleeve pipe and lining resistance in relative rotation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A part cut-away view of the utility model Fig. 1.
Embodiment
By specific embodiment, describe the technical solution of the utility model in detail below, should be understood that, following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
As depicted in figs. 1 and 2, a kind of automobile absorber, comprise sleeve pipe 3 and be placed in sleeve pipe and with the lining of its interference fit, sleeve pipe is fixedly connected with vibration damper 6 bottoms, lining comprises inner tube 1 and is placed in the vulcanized rubber layer 2 on inner tube outer surface, the internal diameter of inner tube 1 is cylindrical, and the outer surface of inner tube is cylindrical or cydariform.The outer surface of inner tube also can be set to other shape as required, only otherwise overslaugh connection with sleeve pipe after vulcanized rubber layer just can.
The outer surface of vulcanized rubber layer 2 is provided with ring projection 4, on the inwall of sleeve pipe 3, be provided with can with the annular groove of the corresponding installation of ring projection; Ring projection and toroidal cavity are rectangle in flattening afterwards.In annular groove, be also axially provided with some grooves 5, groove is three in the present embodiment, and quantity can change as required in other embodiments.In the present embodiment, the center line of groove is for being parallel to sleeve pipe center line, and the radial cross-section of groove is square.
In other embodiment of the present utility model, the radial cross-section of groove is trapezoidal, triangle or arc.
In other embodiment of the present utility model, the center line of groove is non-rectilinear.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present invention is by claims and be equal to and limit.
Claims (5)
