Abstract
The utility model relates to a trailer air suspension assembly convenient to adjust the verticality of a vehicle shaft. Two ends of the vehicle shaft are respectively fixed with a supporting beam hinged with a vehicle beam; a shaft seat of a hinged shaft is fixed with an eccentric sleeve; the axis of the eccentric sleeve is eccentric to the axis of the hinged shaft; the hinged shaft passes through an elongated hole on the eccentric sleeve which is internally sheathed with a washer; the axis of the washer is coaxial to the axis of the eccentric sleeve; the hinged shaft passes through an elongated hole on the washer; the orthographic projections of the elongated hole on the washer and the elongated hole on the eccentric sleeve on the surface of the hinged shaft vertical to the shaft are intersected and overlapped; and the end head of the hinged shaft is connected with a nut which locks the washer and the eccentric sleeve together. The trailer air suspension assembly can lead the front position and the rear position of the hinged shaft to be changed by rotating the washer in the eccentric shaft, thus further adjusting verticality of the vehicle shaft.
Description
Technical field
The utility model relates to the air suspension assembly of the structure of trailer suspension, particularly trailer.
Background technology
The air suspension assembly of trailer comprises axletree, and the two ends of axletree are fixed with a support beam respectively, and the car beam of support beam and trailer is articulated and connected, and is connected with air bellow between the movable end of support beam and the car beam.In the prior art, the position of the jointed shaft that support beam and Che Liang are articulated and connected is fixed, and so just can't regulate the front and back position at axletree two ends by the position of regulating jointed shaft, causes difficulty for the squareness adjusting of axletree and car beam.
The utility model content
The purpose of this utility model provides a kind of trailer air suspension assembly of being convenient to regulate the axletree squareness.
The utility model is achieved in that the trailer air suspension assembly of being convenient to regulate the axletree squareness comprises axletree, the two ends of axletree are fixed with a support beam respectively, the car beam of support beam and trailer is articulated and connected, support beam can swing up and down around jointed shaft, be connected with air bellow between the movable end of support beam and the car beam, especially, on the axle bed of described jointed shaft, be fixed with eccentric bushing, the axle center off-centre of the axle center of eccentric bushing and jointed shaft, offer the strip shape hole on the eccentric bushing, jointed shaft passes this strip shape hole, the length direction in this strip shape hole is parallel with the length direction of car beam, be socketed with packing ring in the eccentric bushing, the axle center of packing ring is coaxial with the axle center of eccentric bushing, offers the strip shape hole on the packing ring, jointed shaft passes the strip shape hole on the packing ring, strip shape hole on the packing ring and the strip shape hole on the eccentric bushing orthogonal projection juxtaposition on jointed shaft hangs down axial plane, the termination of jointed shaft is connected with nut, and nut is locked together packing ring and eccentric bushing.
When regulating the axletree squareness, unclamp the nut on the above-mentioned jointed shaft, packing ring in the rotating eccentric sleeve, the position in the strip shape hole of jointed shaft on eccentric bushing is stirred in strip shape hole on the dependence packing ring, the front and back position of jointed shaft is changed, so jointed shaft drives support beam, the end that support beam drives axletree moves forward and backward together, the angle of axletree and car beam is changed, squareness until axletree meets the demands, after regulating the squareness of axletree, tighten the adjusting that nut on the jointed shaft is promptly finished the axletree squareness again.
The utility model has the advantages that the squareness that to regulate axletree easily, improve the assembly precision of trailer air suspension assembly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A semi-sictional view enlarged drawing of Fig. 1;
Fig. 3 is that the B of Fig. 2 is to partial view.
The specific embodiment
Referring to Fig. 1, Fig. 2, trailer air suspension assembly comprises axletree 1 simultaneously, and the two ends of axletree 1 are fixed with a support beam 2 respectively.Support beam 2 is articulated and connected with the car beam 3 of trailer, and support beam 2 can swing up and down around jointed shaft 4.The jointed shaft 4 of present embodiment is a bolt.Be connected with air bellow 5 between the movable end of support beam 2 and the car beam 3.On the axle bed 6 of jointed shaft 4, be welded with eccentric bushing 7.Simultaneously referring to Fig. 3, the axle center N off-centre of the axle center M of eccentric bushing 7 and jointed shaft 4 (for clear expression eccentric structure, Fig. 3 has saved the bolt cap of jointed shaft 4).Offer strip shape hole 8 on the eccentric bushing 7, owing to blocked by packing ring 9, so the strip shape hole 8 among Fig. 3 is represented by dotted lines.Jointed shaft 4 passes strip shape hole 8, and the length direction in strip shape hole 8 is parallel with the length direction of car beam 3.Packing ring 9 is enclosed within the eccentric bushing 7.The axle center of packing ring 9 is coaxial with the axle center M of eccentric bushing 7, offers strip shape hole 10 on the packing ring 9, and jointed shaft 4 passes this strip shape hole 10.Strip shape hole 10 on the packing ring 9 and the strip shape hole 8 on the eccentric bushing 7 orthogonal projection juxtaposition on jointed shaft hangs down axial plane, as shown in Figure 3.The termination of jointed shaft 4 is connected with nut 11, and nut 11 is locked together packing ring 9 and eccentric bushing 7.
When regulating the axletree squareness, unclamp the nut 11 on the jointed shaft 4, rotate packing ring 9, the position in the strip shape hole 8 of jointed shaft 4 on eccentric bushing 7 is stirred in strip shape hole 10 on the dependence packing ring 9, the front and back position of jointed shaft 4 is changed, that is the position, the left and right sides in Fig. 1 changes, so jointed shaft 4 drives support beam 2, the end that support beam 2 drives axletree 1 moves forward and backward together, the axletree 1 and the angle of car beam 3 are changed, so just the squareness of axletree 1 can be adjusted to and meet the requirements.After regulating the squareness of axletree 1, fastening nut 11 is promptly finished the adjusting to the axletree squareness again, and can be fixed into one this moment with packing ring 9 and eccentric bushing 7 welding.
For the ease of rotating packing ring 9, present embodiment offers eccentric orfice 12 on packing ring 9.Knock eccentric orfice 12 from the tangent to periphery direction of packing ring 9, packing ring 9 is rotated.In addition, also can replace eccentric orfice 12 with a lug that is welded on the packing ring 9.
