Description
Technical field
The utility model is related to transverse arm bushings after automobile.
Background technology
Transverse arm bushing is applied on the one-armed suspension of middle-to-high end car transverse arm afterwards, can make the change of the parameter of wheelspan and wheel alignment
Change amount is limited to allowed band, keeps good riding stability, and can reduce the movement interference of suspension and steering gear connection, no
Easily occur to jump pendulum, it is made widely to apply to the front suspension of car, Light-duty Vehicle etc..Automobile is frequently encountered in normally travel to be turned
To, accelerate, the operating modes such as brake, while by external drive, such as the support of severe road conditions, suspension weight itself；These are external
Factor it is very big to the impact of bushing, this requires bushings other than meeting suitable NVH performances, also to ensure enough
Rigidity to meet the shock loading under different road conditions.Rarely bushing can meet above-mentioned performance requirement at present.
Invention content
The technical problem to be solved by the utility model is to provide transverse arm bushing after a kind of, with it is good it is durable, subtract
Shake, noise reduction and handling；Greatly enhance ride comfort.
The utility model technical scheme applied to solve the technical problem is：Transverse arm bushing after a kind of, including inner core, housing
And the intermediate jacket layer between inner core and housing is arranged in, intermediate jacket layer includes plastics jacket layer and rubber jacket layer, plastics jacket layer
Inner surface is bonded in by inner core combination layer on the outer surface of inner core, the inner ring end face of plastics jacket layer and the end face of inner core,
The end face of plastics jacket layer is equipped with First terrace, and the outer surface of First terrace has the dovetail groove being inwardly recessed, first step
The outer surface in face and the inner surface of rubber jacket layer bond, and the inner surface of rubber jacket layer is with consistent with the inner surface of First terrace
Shape, the end face of rubber jacket layer is equipped with second step face, and second step face is equipped with the annular groove being inwardly recessed, second
The outer surface of terrace and the inner surface of housing bond.
Further, inner core uses the extrusion molding of 40Cr materials as cylindrical sleeves, and two end surfaces of inner core, which are equipped with, to be protruded
In the trapezoidal sawtooth of inner core end face surface, trapezoidal sawtooth is evenly distributed along the axis radioactivity of inner core, when increasing vehicle assembling
Torque and friction coefficient, avoid driving in slide.
Further, the bottom surface of annular groove has the cambered surface of outwardly convex, and the side wall of annular groove is inclined outwardly, this
It is tilted in annular groove and the end face that rubber jacket layer is flushed with First terrace is extended on the side wall of plastics jacket layer.
Further, rubber jacket layer is made of high-strength tear-resistant rubber NR.
Further, housing uses the aluminum sleeve of extrusion molding, and the both ends outer surface of housing has chamfering.
The beneficial effects of the utility model are：The bushing inner core of the utility model selects high rigidity 40Cr materials, ensure that
Enough intensity since plan boundary is smaller, employs plastic technique, and axial rigidity is reduced, and is selected on rubber material
It is good durable heat dissipation performance is selected, tear resistance is good to improve formula, the maximum possible in this way under similary static rigidity
Reduce dynamic rate；Structure can be directed to part and use position simultaneously, on the basis of Static and dynamic stiffness performance is ensured, to greatest extent
Guarantee fatigue, as the main trend of current automotive light weight technology, increase the plastic technique of inner core, alleviated in a kind of degree
The weight of product.Transverse arm bushing is formed using outer skeleton, inner frame, low resistance formula rubber, four partial vulcanization of plastics afterwards, entirely
Part has good durable, damping, noise reduction and handling；Greatly enhance ride comfort.It is new using this practicality
The bush structure of type, for automobile in shock-absorbing and in turning to normal driving process, comfort can be more preferable, noise also smaller, customer experience
It can be more preferable.
