Background technology
Air suspension is mainly used in various vehicles, and its principle of work changes the height of vehicle for pressurized air is delivered in the energy chamber of spring and shock absorber with this.Be provided with the overall height sensor near front-wheel and trailing wheel, by the overall height signal of sensor, microcomputer is judged the variation of bodywork height, controls compressor and blow off valve again, makes length of spring compressed or elongation, thereby plays the effect of vibration damping.Air suspension has given the automobile more flexibility.Suspension can hardening improves the stability of vehicle body when running at high speed; And long-time when the road traveling of low speed injustice, control unit can make the suspension deliquescing improve the traveling comfort of vehicle.
In air suspension, support (or claiming carriage) is a most important load assembly in the whole suspension system, and C type beam is a kind of common supporting structure.
All adopt plate weldment structure in the C type beam traditional design behind the air suspension at present, this structure mold cost height, poor rigidity, cause back axle displacement phenomenon to take place easily, back axle displacement back car load handling variation, the wearing and tearing tire, and cause airsuspension system all to be damaged, even cause the generation of safety misadventure.Simultaneously, welding will be made the above diel of two covers at least, causes die cost higher.
In addition, in the air suspension design commonly used at present, except the main body rack of air suspension, independent longitudinal thrust shaft bar also is set, the horizontal thrust shaft bar, air bellow support, stabilizer bar arm, shock absorber support or the like, number of elements is many, complex structure, and these further cause overall reliability to reduce, the productive costs height is installed problems such as the commonality of complicated and element is low.
Summary of the invention
The objective of the invention is to solve above-mentioned technical matters, provide a kind of assembling simple, the lightweight C type beam that is used for air suspension.
Purpose of the present invention is achieved through the following technical solutions:
A kind of C type beam that is used for air suspension, it has main body, described main body comprises roughly elongated intermediate beam, the two ends of intermediate beam are kink with respect to the bending of main body longitudinally of connection of symmetry respectively, be respectively equipped with the air bellow installation portion on the described kink, described main body integrally casting has on the described main body with respect to the main body symmetrically arranged second general installation portion that is used to install the first general installation portion of longitudinal rod and is used to install Panhard rod of median surface longitudinally.
Further, on the described main body integrally casting be provided with clevis bolt installation portion, bumper installation portion.
Further, described clevis bolt installation portion comprise two be provided with at interval, adapter plate parallel to each other, each adapter plate is provided with two corresponding mounting holes that are provided with, described adapter plate is located at the bottom of intermediate beam, its bearing of trend is perpendicular to the bearing of trend of intermediate beam.
Further, described bumper installation position is included in the first bumper installation region and the second bumper installation region that are symmetrically distributed on the longitudinally of intermediate beam in the top of intermediate beam.
Further, the described first general installation portion and the second general installation portion are positioned at the two ends of intermediate beam respectively, roughly become U-shaped separately, have cave in zone and two ends, and described two ends are provided with mounting hole.
Further, have the mounting plane that caves inward on the described end, described mounting plane has the drift angle of circular arc.
Further, has hollow space on the described intermediate beam.
Beneficial effect of the present invention is mainly reflected in: on the C type beam integrally casting mounting portion of multiple parts, the intensity height, the not yielding back axle displacement phenomenon that can not cause takes place, and has well guaranteed the performance of airsuspension system.C type beam of the present invention has the mounting portion and the hollow space of the rational Design on Plane of symmetry, and convenient the installation reduces stress concentration, expendable weight, and maximization has guaranteed General design.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is the front view of specific embodiments of the invention.
Fig. 2 is the back view of specific embodiments of the invention.
Fig. 3 is the lateral plan of specific embodiments of the invention.
Wherein:
1 intermediate beam, 9 second general installation portions
3 kinks, 11 clevis bolt installation portions
5 air bellow installation portions, 13 bumper installation portions
7 first general installation portions
The specific embodiment
The present invention has disclosed a kind of C type beam that is used for air suspension, referring to figs. 1 through Fig. 3, comprises main body, it is the cast-in-block steel casting, roughly be the C type, it comprises and is positioned at centre portion, roughly the intermediate beam 1 of elongated shape and be separately positioned on two kinks 3 of two ends of intermediate beam.
Intermediate beam 1 is excavated a part, is formed with hollow space.Hollow space needs not to be and penetrates, and it also can be the groove of the depression on the intermediate beam, and like this, the main portion of the intermediate beam 1 of main body is used for load-bearing, and hollow space then can alleviate the weight of C type beam.This has solved the big problem of cast-in-block C type beam weight.And the structure design that the centre hollows out has guaranteed casting manufacturability, reduces foundry defect, has increased intensity.
Two kinks 3 stretch out from the two ends of intermediate beam 1, yet its initiating terminal only occupies the part of the terminal surface of intermediate beam 1.Two kinks 3 are mutually symmetrical, and all are provided with air bellow installation portion 5 on its end, and air bellow installation portion 5 diamondwises have mounting hole on it.
Two ends of intermediate beam 1 also form the first general installation portion 7 and the second general installation portion 9 of symmetry respectively.They all roughly become U-shaped, have cave in zone and two ends, and described two ends are provided with mounting hole.The first general installation portion 7 is used to install longitudinal rod, and the second general installation portion 9 is used to install Panhard rod.
Have the mounting plane that caves inward on the described end, described mounting plane has the drift angle of circular arc, and the shape of mounting plane has reduced stress concentration, and the installation of the longitudinal rod that takes into full account.
Because the shape of the first general installation portion 7 and the second general installation portion 9, the position with respect to intermediate beam 1 vertically on the setting of median surface symmetry, make the part universality of air suspension strengthen.
That goes back integrally casting on the described main body is provided with clevis bolt installation portion 11, bumper installation portion 13.
Clevis bolt installation portion 11 comprise two be provided with at interval, adapter plate parallel to each other, each adapter plate is provided with two corresponding mounting holes that are provided with, described adapter plate is located at the bottom of intermediate beam, its bearing of trend is perpendicular to the bearing of trend of intermediate beam.Two clevis bolts can be installed on the clevis bolt installation portion 11, and each clevis bolt is connected across in the mounting hole of two homonymies on the adapter plate.
Bumper installation portion 13 is positioned at the top of intermediate beam 1, is included in the first bumper installation region and the second bumper installation region that are symmetrically distributed on the longitudinally of intermediate beam 1.
The present invention still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
