Description

A kind of automobile swing arm
Technical field
The present invention relates to technical field of automobile parts, in particular to a kind of automobile swing arm.
Background technique
Suspension system is assembly important on Hyundai Motor, and the ride comfort and operational stability to running car have very big shadow It rings.Guiding and force transfer element of the swing arm as automobile suspension system act between wheel and vehicle frame and are used to transmission force and power torsion Part, swing arm passes through flexural pivot or bushing respectively and wheel and flexible chassis linked together, and can be used to buffer by not Flat road surface is transmitted to the impact force of vehicle frame or vehicle body, and shakes caused by decaying thus, while playing and guaranteeing wheel by certain track The effect of movement.
But most of automobile swing arms on market today are in C character form structure (referring to Fig. 1), in the prevalence of weight Greatly, the disadvantages of rigidity is low, and bearing capacity is weak, and the integrated degree of control arm is low, the conjugation of rubber bushing and swing arm is not high, These all bring very big hidden danger to the operation of automobile.
And existing swing arm, during body movement, easily there is stress concentration in swing arm, and intensity and durability are poor, and And installation axle axially along vehicle X-direction, right bushing need to be fixed with bracket, thus increase control arm assembly weight Amount, further, since installation axle axially along vehicle X-direction, left bushing and right bushing swing angle is larger is prone to wear out, it is fixed to need Phase is replaced, and maintenance cost, the equal urgent need to resolve of the above problem are increased.
So how to design, a kind of structure is reliable and light-weighted automobile swing arm, and becoming us will currently solve the problems, such as.
Summary of the invention
In view of this, the present invention is directed to propose a kind of automobile swing arm is answered with overcoming the big rigidity of the weight in traditional structure low Power is concentrated and bearing capacity is weak and can not the drawbacks such as damping, buffering.
