Description
Technical field
Automobile manufacturing field is the utility model is related to, more particularly to a kind of air suspension suspension strut.
Background technology
Air suspension is mainly used in various load-carrying vehicles, and its operation principle is to deliver compressed air to spring and shock absorber
Air chamber in, height during vehicle pressure-bearing is changed with this.Vehicle height sensor is provided near front wheels and rear wheels, by overall height
The output signal of sensor, microcomputer judge the change of bodywork height, then control compressor and air bleeding valve, make spring-compressed or stretch
It is long, so as to play the effect of vibration damping.Air suspension gives automobile more flexibilities.When running at high speed, suspension can be hardened
To improve the stability of vehicle body；And for a long time in the uneven road traveling of low speed, control unit can make suspension soften to improve
The comfortableness of car.
In air suspension, support, or bracket, suspension are most important load assemblies in whole system.At present, use
Mainly there are two kinds of structures of monoblock cast and punch welding in the support of air suspension.Because support volume is larger, monoblock cast knot
The bracket weight of structure is often larger, and excessive weight can influence the dynamic property of vehicle, and the big single-casting of shape is being cast
Easily produce sand holes when making, it is loose the defects of, to cast and machining in terms of require higher.Existing frequently-used support uses
Punch welding structure, overall weight are lighter.However, punch welding, there is also defect, it will at least manufacture more than two sets of punching press
Mould, and also need lined structure using welding between the various pieces of support to improve intensity, cause die cost and weldering
It is higher to be connected into this.In addition, in currently used air suspension design, except the main body rack of air suspension, also set up individually
Trailing link support, bracket for horizontal push rod, air spring support, stabilizer bar arm, shock absorber support etc., number of elements
More, complicated, these further result in overall reliability reduction, and production cost is high, and installation is complicated low with the versatility of element
The problems such as.
Therefore, for above-mentioned phenomenon, a kind of support for air suspension is just refer in patent CN101927673A,
It has a main body of monoblock cast, the main body has a hollow space, and is provided with main body integrally connected：Air spring is pacified
Dress portion；Upper thrust rod installation portion；Anti-sway bar installation portion；QS installation portion；Lower thrust rod installation portion；Damper is pacified
Dress portion.The air spring installation portion be perpendicular to main body supporting station, the mistake between the air spring installation portion and main body
Part is crossed into inclined plane shape, the transition portion between the upper thrust rod installation portion and main body is into uniform circular arcs shape.This practicality
It is new by integrally casting be used for air spring support on hollow space is set, effectively reduce weight support frame and add
Intensity, and the integrally casting mounting portion of a variety of parts on support of the present utility model, reduce materials and parts quantity, simplify dress
Match somebody with somebody, reduce cost.
Support in said structure, because it needs part to be mounted more, and in order to ensure that the structure of support in itself is strong
Degree, it is necessary to which the thickness for the comparison for doing support, the weight that its corresponding weight will compare, overall structure are heavier.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of air suspension suspension strut in light weight.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of air suspension suspension strut, this is outstanding
The upper end of frame support is connected with the longeron of air suspension, and a saddle is also associated between suspension strut and the upper end junction of longeron
Seat connecting plate, lower end are connected with the straight push rod of air suspension, and its innovative point is：Including
One suspension strut main body, the Y-shaped shape of suspension strut main body, there are a pair in suspension strut main body from suspension
The upper end of rack body extends to the reinforcement of the lower end of suspension strut main body；
There is a longeron connection unit in the upper end of suspension strut main body, the longeron connection unit is located at suspension including one
The longeron connecting seat of rack body upper position, there is a U-shaped groove, the longeron in the upper center position of longeron connecting seat
There are several holes that connect one to one with longeron on connecting seat, it is small with the wall thickness of saddle coupling board junction on longeron connecting seat
In the wall thickness of longeron connecting seat remainder, and the reduction amount of wall thickness and the consistency of thickness of saddle coupling board；
There is push rod connection unit always in the lower end of suspension strut main body, the straight push rod connection unit includes a contraposition
Straight push rod connecting seat in suspension strut lower body part position, gap is left between two straight push rod connecting seats, so that
The lower end of suspension strut main body has an arc-shaped slot, has one to hold straight push rod on straight push rod connecting seat and installs and be horizontally disposed with
Straight push rod installation through-hole.
Further, the both ends of the suspension strut main body are provided with lightening grooves.
Further, the straight push rod connecting seat is in kidney-shaped shape.
Further, the connecting hole that muscle covering is reinforced on the longeron connecting seat is blind hole, and remaining hole is through hole.
The utility model has the advantage of：Suspension strut in the utility model only needs for longitudinal beam connected and directly to push away
Bar, reduce suspension strut connection burden, therefore suspension strut can be done it is thin, to mitigate the weight of suspension strut, in addition
A U-shaped groove is opened in upper end again, further mitigates the weight of whole suspension support, meanwhile, set up on suspension strut from upper
The reinforcement extended downwardly, to demonstrate,prove the structural strength of suspension strut.
Setting for longeron connecting seat, it is thin by the way that the upper end of longeron connecting seat is done, to coordinate suspension strut, saddle to connect
Connection between fishplate bar and longeron, avoid causing because of the presence of saddle coupling board occurring after connecting between suspension strut and longeron
Gap, and have influence on the stabilization of connection.
By reducing Baking soda at the both ends of suspension strut main body, further mitigate suspension strut overall weight so as to reach
Purpose, the lightweight for follow-up overall air suspension provides basis；And for the design of straight push rod connecting seat, using kidney-shaped
The structure of shape so that the surplus of straight push rod connecting seat is big, facilitates the processing of straight push rod installation through-hole.
In the utility model, by the way that the connecting hole that muscle covering is reinforced on longeron connecting seat is designed as into blind hole, without
It is through hole, so as on the basis of ensureing to connect, avoid having influence on the structure of reinforcement because processing through hole, ensures overall structure
Intensity.
