Technical field
The utility model belongs to technical field of automobile accessories, is related to a kind of automotive suspension accessory, in particular to a kind of automobile
Suspension bushing.
Background technique
Suspension is the assembly of all force transmission connections of the vehicle frame of automobile between vehicle bridge, and effect is that transmitting acts on
Power and torque between wheel and vehicle frame, and the impact force that vehicle frame or vehicle body are transmitted to by uneven road surface is buffered, and reduce thus
Caused vibration, to guarantee that automobile can be travelled smoothly, wherein bushing plays extremely important shock absorbing effect.
Such as Chinese patent literature data discloses a kind of automobile hanging rubber bushing [application number: 201520343653.X；
Authorization Notice No.: CN204628389U] comprising bushing rubber, the outer liner tube being coated on outside bushing rubber and in bushing rubber
The internal lining pipe of gluing knot together, be arranged on outer liner tube a cast steel installation shell, cast steel install shell both sides of the face with
Outer liner tube both sides of the face are corresponding.
Above-mentioned automobile hanging rubber bushing installs the setting of shell by cast steel, to outer liner tube, bushing rubber and liner
The extruding force of pipe is uniformly reasonable, so that structure is not easy to loosen, but its construction weight is heavier, is not content with the automobile pursued at present
Light-weight design requirement, and buffering effect is also not ideal enough, and the connection area of internal lining pipe and bushing rubber is few and to connect
It is bad to connect fastness, when by larger axial impact loading, bushing rubber is easily torn with internal lining pipe, if increased outside internal lining pipe
Diameter then can increase the connectivity robustness of internal lining pipe and bushing rubber, can be bound to cause weight increase.
Summary of the invention
The purpose of this utility model is to provide a kind of light-weight, buffering for the above-mentioned problems in the prior art
Property automotive suspension bushing good and that be avoided that rubber layer tearing.
The purpose of this utility model can be realized by the following technical scheme: a kind of automotive suspension bushing, including outer lining

Shape has spacing when each limb body is fixed on rubber layer outer wall between adjacent sheet body.The filling of rubber layer when manufacturing in this way
Amount is big, and when outer liner tube elastic conjunction is in pipe sleeve, each limb body is close to each other to oppress rubber layer, so that rubber layer has very well
Bearing capacity, and rubber layer provide reset force so that sheet body has the trend for contacting at pipe sleeve inner wall always, to make
Connectivity robustness after obtaining outer liner tube assembly is high.
In a kind of above-mentioned automotive suspension bushing, the plastic layer is equipped in the middle part of each through-hole to be connected together
Connect the reinforcing rib for two arcwalls that hole has.Make plastic layer structural strength good in this way, bearing capacity is good.
In a kind of above-mentioned automotive suspension bushing, if the outer wall of the plastic layer has arterial highway circumferentially uniformly distributed and axis
To the protrusion of extension.Protrusion increases the contact area of plastic layer and rubber layer, and connectivity robustness is good, and plastic layer transmitting is turned round
Square process is steady, and rubber layer will not be torn.
In a kind of above-mentioned automotive suspension bushing, the rubber layer has the buffering for being symmetrical arranged and axially penetrating through
Hole, the cushion hole in the middle part of the hole wall of outer liner tube radially protruding and this hole wall from middle part to both ends by conical surface transition,
Cushion hole is cylinder planar close to the hole wall of plastic layer.Cushion hole not only acts as loss of weight effect, and increases the bullet of rubber layer
Property, the cushion performance of rubber layer is improved, when rubber layer is impacted by radial load, deformation first at cushion hole, cushion hole
It plays and keeps out and supporting role in the middle part of the hole wall of outer liner tube, so that the buffer function of rubber layer linearly increases, so that slow
Rush effect ideal.
In a kind of above-mentioned automotive suspension bushing, the plastic layer and internal lining pipe is isometric and the both ends of the two are super
Rubber layer both ends are arranged out, the rubber layer plastic covering layer outer wall setting.The assembly area of internal lining pipe in this way is more, after assembly
Connectivity robustness is good, and rubber layer and plastic layer connection area are big, is connected firmly, and rubber layer will not be torn.
In a kind of above-mentioned automotive suspension bushing, the both ends of the plastic layer all have step.Plastic layer both ends
Positioning action is played, gasket location and installation is convenient for.
Compared with prior art, this automotive suspension bushing is light-weight, meets light-weight design requirement, and structure is steady
Gu torque transmitting is stablized, cushion performance is good, and rubber layer will not be torn, good operating stability, long service life.
