Description
Technical field
The present invention relates to a kind of suspension coupling structure, be specifically related to a kind of full welded type Pneumatic Suspension coupling structure be applied on trailer.
Background technology
Present automobile all is provided with suspended structure, suspension is the general name of vehicle frame and all the power transmission connecting devices between vehicle bridge, axletree or wheel of automobile, the Main Function hung is transfer function all force and moments between wheel and vehicle body, such as bearing force, braking force and propulsive effort etc., and relax by uneven road surface pass to vehicle body impact load, vibration, the traveling comfort that guarantees the occupant that decay causes thus, reduce the live load of goods and vehicle itself.Between existing Automobile shaft and vehicle frame, be by hanging, both firmly to be tied, the commonly used leaf spring that has hangs and Pneumatic Suspension at present, and Pneumatic Suspension hangs ride comfort and the traveling comfort that more can improve running car than leaf spring, improved the transporting cargo safety, and minimizing is to the damage of highway pavement, play the effect of maintaining public highway, thereby more applied gradually.On current superimposed trailer world market, hanging with the connecting structure of axletree is all to clamp with U-bolt basically, with the part welding manner, circle or square axletree is fixed in suspension again, to reach anti-rotation and the purpose that prevents the axletree end float misalignment, this suspended structure is called half welded type and hangs coupling structure, as shown in Figure 1.Particularly on Pneumatic Suspension, with being connected of semitrailer axle 2, be all to adopt welding manner to be arranged on suspension assembly 1 basically, some producers add U-bolt 4 both are tied on the basis of welding, this mode shortcoming be that the defect that cracking even lost efficacy easily appears in axis body near position of weld; The rear easily appearance of transportation is loosening for a long time at automobile for bolt, makes the ratio of the traffic accident that axle and vehicle frame disengaging occur very high, adopts two kinds of this double combination modes to increase processing technology step and complexity simultaneously, and economic benefit is lower.At present, some country has put into effect regulation, uses this frame mode axletree and suspension are linked together with bolt on restricting vehicle.
Summary of the invention
The object of the invention is to for the problems referred to above weak point, provide a kind of simple in structure, connect solid and reliable full welded type Pneumatic Suspension coupling structure, it can reduce materials being fabricated and reduce the processing technology complexity, stops bolt and partly is welded to connect the potential safety hazard of bringing.
In order to achieve the above object, the present invention is by the following technical solutions:

Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The specific embodiment
As shown in Fig. 2 to 5, full welded type Pneumatic Suspension coupling structure of the present invention, comprise suspension assembly 1 and axletree 2, and described suspension assembly 1 comprises girder 11, air bellow 12, bumper 13 and front frame 14, and concrete structure is as follows:
Described girder 11 is provided with for the opened type arch axle bed 15 of axletree is installed, the installation position profile of this opened type arch axle bed 15 is the minor arc shape, further, the installation position profile of described opened type arch axle bed 15 is the minor arc shape that is greater than 120 ° and is less than 180 °, wherein, as most preferred embodiment, the installation position profile of described opened type arch axle bed 15 is the minor arc shape of 170 °, because the installation position profile of opened type arch axle bed 15 is less than 180 ° of semicircles, it has reduced the materials of girder 11 on the one hand, convenient the installation on the other hand, when entering location and installation, axletree 2 gets final product by uncovered positive the embedding, without adopting side direction to intert, enter, fast and easy.Further concrete, the string face A of described opened type arch axle bed 15 and the sharp angle α between horizontal surface B are 30 ° to 60 °, and the horizontal surface here refers to plane of reference parallel with the girder upper surface when girder upper surface 111 levels are put.Wherein, as most preferred embodiment, string face A and the sharp angle α between horizontal surface B of described opened type arch axle bed are 47 °, and this sharp angle setting can guarantee the girder load that dispersed axletree transmission comes up in the main stress district, improve the performance of full welded type Pneumatic Suspension.
Described opened type arch axle bed 15 half is encircled and is welded and fixed axletree 2, and described axletree 2 is the circle axletree, and the welded and installed position profile of its weld profile and opened type arch axle bed 15 is suitable.As preferred embodiment: between described axletree 2 and opened type arch axle bed 15, be provided with an axle sleeve 3, these axle sleeve 3 outsides are welded and fixed with opened type arch axle bed 15, inner and axletree 2 is welded and fixed, further concrete, by two, to halfliner, splicing forms described axle sleeve 3, described axletree 2 is the circle axletree, the welded and installed position profile of the outside weldings position profile of described axle sleeve 3 and opened type arch axle bed 15 is suitable, and the interior welds position profile of described axle sleeve 3 and axletree 2 weld profiles suitable.Increasing by an axle sleeve 3 between axletree 3 and opened type arch axle bed 15 is welded to connect, be conducive to increase face of weld, make welded structure more firm, if directly adopt axletree 2 and girder 11 solder bond, its face of weld will be little a lot, increased axle sleeve 3, increased on the one hand the diameter of axletree 2, make the installation position profile camber line of opened type arch axle bed 15 longer to coordinate the outside weldings position profile of axle sleeve 3, increased the length of weld seam, to have increased axletree 2 weld width and range on the other hand, if axletree 2 directly welds with girder 1, its weld tightly is limited to the position contacted with girder so, and after increasing axle sleeve 3, axletree 2 welding cover whole axle sleeve 3 edges, therefore welded structure is more firm.
During welding processing, first axle sleeve 3 is welded on the relevant position that axletree 1 is connected with opened type arch axle bed 15, then the corresponding opened type arch of axle sleeve 3 axle bed 15 is welded, processing technology is simple, and efficiency is high.
The present invention is welded and fixed axletree by opened type arch axle bed is set on the girder hung, and for the happy bonding area that increases increases the welding axle sleeve between the two at it, simple in structure, connect solid and reliable, can reduce materials being fabricated and reduce the processing technology complexity, stopping bolt and partly be welded to connect the potential safety hazard of bringing.
