Description
Technical field
The present invention relates to a kind of suspension coupling structure, be specifically related to a kind of full welding type applied on trailer empty
Gas hangs coupling structure.
Background technology
Present automobile is designed with suspended structure, and suspension is between the vehicle frame of automobile and vehicle bridge, axletree or wheel
The general name of all force transmission connections, the Main Function of suspension is that transmission acts between wheel and vehicle body
One shear force and moment, such as support force, brake force and driving force etc., and relax and passed to car by uneven road surface
The vibration that the shock loading of body, decay thus cause, the comfortableness ensureing occupant, reduction goods and vehicle are originally
The dynamic loading of body.It is by hanging both electrical connection, at present between existing Automobile shaft and vehicle frame
The conventional leaf spring that has hangs and air suspension, and air suspension hangs than leaf spring and more can improve the flat of running car
Pliable and comfortableness, improves transport cargo security, and reduces the damage to highway pavement, play maintenance
The effect of highway, thus the most more applied.On current semitrailer international market, hang and car
The connecting structure of axle is essentially all and clamps with U-bolt, then with part welding manner by circular or
Square axletree is fixed in suspension, to reach anti-rotation and to prevent the purpose of axletree axial float, this suspension
Structure is referred to as half welding type and hangs coupling structure, as shown in Figure 1.Particularly on air suspension, with semi-mounted
The connection of car axletree 2 is essentially all employing welding manner and is arranged on suspension assembly 1, and some producers are in welding
On the basis of add U-bolt 4 both be tied, this mode shortcoming be that axis body is in welding
The most cracking defect even lost efficacy near position；Bolt easily occurs after automobile transports for a long time
Loosen so that the ratio of the traffic accident that generation axle departs from vehicle frame is the highest, use two kinds of this binodes simultaneously
Conjunction mode adds processing technique step and complexity, and economic benefit is relatively low.At present, some country has gone out
Platform specifies, restricting vehicle uses this frame mode axletree and suspension being linked together with bolt.
Summary of the invention
Present invention aims to the problems referred to above weak point, it is provided that a kind of simple in construction, connection are firmly
Reliably full welding type air suspension coupling structure, it can reduce materials being fabricated and reduce processing technique complexity,
Stop bolt and be partly welded to connect the potential safety hazard brought.
In order to achieve the above object, the present invention is by the following technical solutions:
Full welding type air suspension coupling structure, including suspension assembly and axletree, described suspension assembly includes one
Girder, described girder caves inward and is formed for installing the opened type arch axle bed of axletree, and opened type arch

Sharp angle between chord plane and the horizontal plane of described opened type arch axle bed is 30 ° to 60 °.
Sharp angle between chord plane and the horizontal plane of described opened type arch axle bed is 47 °.
Described axletree is circle axletree, the welded and installed position wheel of its welding position profile and opened type arch axle bed
Wide suitable.
Described axletree is circle axletree, the outside weldings position profile of described axle sleeve and the weldering of opened type arch axle bed
Connect installation position profile suitable, and the interior welds position profile of described axle sleeve and axletree welding position profile
Suitable.
The present invention is welded and fixed axletree by arranging opened type arch axle bed on the girder hung, simple in construction,
Couple solid and reliable, materials being fabricated can be reduced and reduce processing technique complexity, stopping bolt and be partly welded to connect
The potential safety hazard brought.

Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Detailed description of the invention
As Fig. 2 is to shown in 5, and full welding type air suspension coupling structure of the present invention, including suspension group
Part 1 and axletree 2, described suspension assembly 1 includes girder 11, air spring 12, amortisseur 13 and fore-stock
14, concrete structure is as follows:
Described girder 11 caves inward and is formed for installing the opened type arch axle bed 15 of axletree, and opened type arch
The installation position profile of oblique crank Z seat 15 is minor arc shape, further, and the installation of described opened type arch axle bed 15
Position profile is in the minor arc shape more than 120 ° and less than 180 °, wherein, as most preferred embodiment, described spacious
The installation position profile of mouth formula arch axle bed 15 is the minor arc shape of 170 °, due to opened type arch axle bed 15
Installation position profile is less than 180 ° of semicircles, and on the one hand it decrease the materials of girder 11, the on the other hand side of being
Just install, embedded by uncovered front when axletree 2 enters location and installation, it is not necessary to use laterally intert into
Enter, fast and easy.The most concrete, between chord plane A and the horizontal plane B of described opened type arch axle bed 15
Sharp angle α be 30 ° to 60 °, horizontal plane here refers to when girder upper surface 111 level is put and master
The plane of reference that beam upper surface is parallel.Wherein, as most preferred embodiment, chord plane A of described opened type arch axle bed
And the sharp angle α between horizontal plane B is 47 °, this sharp angle arranges and can ensure that girder is equal in main stress district
Even dispersion axletree transmits the load come up, and improves the performance of full welding type air suspension.
Described opened type arch axle bed 15 half is encircled and is welded and fixed axletree 2, and described axletree 2 is circle axletree, its
Welding position profile is suitable with the welded and installed position profile of opened type arch axle bed 15.As being preferable to carry out
Scheme: be provided with an axle sleeve 3 between described axletree 2 and opened type arch axle bed 15, this axle sleeve 3 is outside and spacious
Mouth formula arch axle bed 15 is welded and fixed, and inside is welded and fixed with axletree 2, the most specifically, and described axle sleeve 3
Being formed halfliner splicing by two, described axletree 2 is circle axletree, the outside weldings position of described axle sleeve 3
Profile is suitable with the welded and installed position profile of opened type arch axle bed 15, and the internal welding of described axle sleeve 3
Connect position profile suitable with axletree 2 welding position profile.Between axletree 3 and opened type arch axle bed 15
Increase by an axle sleeve 3 to be welded to connect, be conducive to increasing solder side, make Welding Structure more firm, if directly adopted
By axletree 2 and girder 11 solder bond, its solder side will be much smaller, adds axle sleeve 3, on the one hand increases
Having added the diameter of axletree 2, the installation position profile camber line making opened type arch axle bed 15 is longer to coordinate axle sleeve
The outside weldings position profile of 3, i.e. adds the length of weld seam, and on the other hand being the increase in axletree 2 welds width
Degree and range, if axletree 2 directly welds with girder 1, then its welding position is tightly limited to contact with girder
Position, and after increasing axle sleeve 3, axletree 2 welding covers whole axle sleeve 3 edge, therefore Welding Structure
More firm.
During welding processing, first axle sleeve 3 is welded on the corresponding positions that axletree 1 is connected with opened type arch axle bed 15
Putting, then corresponding for axle sleeve 3 opened type arch axle bed 15 is welded, processing technique is simple, and efficiency is high.
The present invention is welded and fixed axletree by arranging opened type arch axle bed on the girder hung, and increases for happy
Add bonding area and increase welding axle sleeve between them, simple in construction, couple solid and reliable, system can be reduced
Make materials and reduce processing technique complexity, stopping bolt and be partly welded to connect the potential safety hazard brought.
