Background technology
Air suspension mainly adopts air bellow as elastic element, is made up of, can only bears vertical load the rubber bag tank accompanying cord with the pressurized air being filled with its inner chamber.Based on this feature, therefore need guiding mechanism in such systems to bear and transmit the force and moment beyond vertical power.In addition the guiding mechanism on steering shaft also should be able to control wheel orientation angle to be changed in rational scope, and when turning to, wheel can have reasonable sideslip angle reasonably to control car load ground understeering effect.The layout of guiding mechanism and with movement relation to the ride comfort of car load, riding stability, the wear pattern of " nodding " and tire can be resisted when emergency braking.
Mostly current air suspension is on the market to adopt installs air bellow by air bellow lower bracket in the middle part of two block plate springs, structure is all very complicated with assembling, and air bellow itself has certain inclination angle, therefore assembling after air bellow Impact direction and air bellow axis inconsistent, affect the service life of air bellow, therefore those skilled in the art are devoted to develop that a kind of structure is simple, the air suspension of longer service life.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide that structure is simple, the air suspension of longer service life.
For achieving the above object, the utility model provides a kind of novel front composite air suspension, comprise first steel spring overlapping up and down and second steel spring, the front end of first steel spring is provided with bag ear and wraps in second steel spring, termination, described first steel spring rear end upwarps, the upper surface of first steel spring rear end and the angle of horizontal surface are α, α is 2 ° ~ 2.5 °, the upper surface of this first steel spring is connected with air bellow by air bellow lower bracket, the top of described air bellow is connected with air bellow frame brackets, the front portion of the front portion of first steel spring and second steel spring is connected with clip jointly, described clip comprises inside collar and outside collar, this inside collar and outside collar are " U " shape structure, inside collar is positioned at outside collar, and the opening of this inside collar and outside collar is arranged all down, the two side of inside collar is fixed on the two side of outside collar respectively by screw, the screw cap of this screw is positioned at the U-shaped of inside collar, described first steel spring and second steel spring are between the upper surface and outside collar of inside collar, this second steel spring is connected by rivet with inside collar, and the rivet cap of this rivet is positioned at the U-shaped of inside collar.
Use the air suspension of said structure, air bellow is not arranged in directly in the middle part of bridge, but be arranged in the rear end of first steel spring, both simplified be arranged in middle part more complicated and be not easy to assemble air bellow lower bracket, be convenient to again saddle clamp clamping for carrying and the steel spring play the guiding role, tilt upward in first steel spring rear end simultaneously, the angle of kingpin caster angle can be ensured, can ensure that again assembling rear air bellow can keep level, ensure that vertical Impact direction prevent air bellow when up and down jump its axis deviation consistent with air bellow axis is large, improve the service life of air bellow.Outer clamp is connected with interior clamp screw simultaneously, instead of connects with bolt, nut, and avoid transverse direction and other part to interfere, outer clamp is opening down avoids other part around vertical direction and vehicle body to interfere.
Be provided with rubber block between described first steel spring and outside collar, the upper surface of this rubber block raises up formation projection, and this projection extend in shrinkage pool corresponding on outside collar.When this structure can avoid steel spring to bounce, first steel spring and outside collar collide generation noise.
Be provided with middle part pad above the middle part of described second steel spring, in the middle part of this, pad is positioned at the below of first steel spring, and in the middle part of this, pad and first steel spring, second steel spring is equipped with center bolt jointly.Middle part pad can prevent the tail end of first steel spring and second steel spring from producing interference.
In order to simplified structure is convenient to assembling, described air bellow lower bracket rides in first steel spring, and the tail end side of this first steel spring is equipped with binding bolt, and air bellow lower bracket and first steel spring are fixedly linked by this binding bolt.
As preferably, described α is 2.2 °.
The beneficial effects of the utility model are: the utility model adopts novel air suspension structure, can not only simplified structure, improve efficiency of assembling, also there is the feature improving air bellow service life simultaneously.
