For example, regulating plate 3 is isosceles triangle with axle sleeve 6 complex structural shape, if so structure still can fix a position for regulating plate 3 can be installed fast with axle sleeve 6, thereby removes the setting element from.
Optionally, in some embodiments of the present invention, referring to fig. 4 and 5, a first positioning member 7 is disposed on the shaft sleeve 6 (at a portion contacting with the suspension bracket 4). When the adjusting plate is installed, the direction of the long round hole of the shaft sleeve 6 is consistent with the eccentric direction of the round hole of the adjusting plate 3; this direction does not necessarily coincide with the air suspension pilot arm direction, but is sufficient as long as the air suspension pilot arm position can be adjusted; in order to quickly mount the shaft sleeve 6 on the suspension bracket 4 and ensure that the direction of the long round hole of the shaft sleeve is consistent with the eccentric direction of the round hole of the adjusting plate 3, a first positioning piece 7 is arranged on the shaft sleeve 6 (the part in contact with the suspension bracket 4), meanwhile, a positioning piece is arranged on the corresponding part of the suspension bracket 4, and the first positioning piece 7 on the shaft sleeve 6 is matched with the positioning piece on the suspension bracket 4 and can be mutually clamped and quickly positioned.
Optionally, in some embodiments of the present invention, referring to fig. 4 and 5, a second positioning element 9 is disposed on the shaft sleeve 6 (a portion contacting the adjusting plate 3). When the adjusting plate is installed, the direction of the long round hole of the shaft sleeve 6 is consistent with the eccentric direction of the round hole of the adjusting plate 3; the direction of the eccentricity of the circular hole of the adjusting plate 3, i.e. the direction of the connecting line of the center of the adjusting plate and the center of the circular hole, is not necessarily consistent with the direction of the air suspension guide arm, but only needs to be adjusted. In order to quickly mount the adjusting plate 3 on the shaft sleeve 6 and ensure that the direction of the long round hole of the shaft sleeve 6 is consistent with the eccentric direction of the round hole of the adjusting plate 3, a second positioning part 9 is arranged on the shaft sleeve 6 (at the position contacted with the adjusting plate 3), a third positioning part 10 is arranged at the corresponding position on the adjusting plate 3, and the second positioning part 9 on the shaft sleeve 6 is matched with the third positioning part 10 on the adjusting plate 3 and can be mutually clamped and quickly positioned.

Alternatively, in some embodiments of the invention, the adjustment plate 3 is directly connected to the suspension bracket 4. The shaft sleeve 6 is omitted, and the structure of the adjusting plate 3, such as the outer diameter, the thickness and the like, is adjusted to be suitable for being directly connected with the suspension bracket 4 and matched for use.
The utility model provides a trailer suspension support adjusts mode of structure, the round hole of regulating plate 3 sets up to different eccentric numerical values, forms the regulating plate 3 of a series of different specification models, and through changing regulating plate 3, the air suspension leading arm drives axle position and removes to reach the purpose of adjustment wheel base. According to the embodiment, the position of the circular hole of the adjusting plate 3 is eccentric, the range of the eccentric value A is 0-20mm, a group of adjusting plates 3 with different specifications and models are formed by different eccentric values, and the position of the bolt 5 is changed when the adjusting plates 3 with different specifications and models are replaced. The direction of installation of the elongated hole of the boss 6 in the suspension bracket 4 determines the direction of eccentricity of the circular hole of the adjusting plate 3, and in order to adapt to the value of the adjusting wheel base, it is necessary to calculate which eccentric value of the adjusting plate 3 is used. The bolt 5 is a connecting piece of the air suspension guide arm and the suspension bracket 4, namely the bolt 5 passes through a damping sleeve of the air suspension guide arm and a shaft sleeve 6 of the suspension bracket 4, passes through a hole of the adjusting plate 3, is fastened by the flat cushion 2 and the nut 1, and is used for connecting the air suspension guide arm with the suspension bracket 4, the air suspension guide arm is connected with an axle of an axle, and once the position of the bolt 5 is changed, the air suspension guide arm drives the axle to move, so that the purpose of adjusting the axle distance is achieved. The different eccentric numerical values of the round holes on the adjusting plate 3 mean that the distances between the centers and the edges of the round holes on the adjusting plate 3 are different, the distances between the centers and the edges of the round holes on the adjusting plate 3 are different to form a group of adjusting plates 3 with different specifications and models, and the directions from the centers of the round holes on the adjusting plate 3 to the edges with different distances are consistent with the direction capable of adjusting the axle distance. Preparing an adjusting plate 3 with different eccentric values of the system, marking, and when the adjusting plate 3 needs to be replaced, replacing the adjusting plate quickly according to the abrasion loss of different degrees. In conclusion, the installation direction of the long hole formed by the shaft sleeve in the suspension bracket 4 determines the value of the circular hole eccentricity of the adjusting plate 3, so that how to use the adjusting plate 3 with the proper eccentricity value can be obtained only by calculation. Meanwhile, if the shaft sleeve is provided with a long hole, the installation direction of the adjusting plate 3 is guided; if the adjusting plate is a large round hole, the installation direction of the adjusting plate cannot be guided, and the adjusting plate can be adjusted properly by manpower. In addition, the prior art only has one eccentric value for achieving the purpose of eccentricity, and the invention forms a series of adjusting plates 3 for achieving the purpose of adjustment for a plurality of eccentric values, namely the prior art only uses an adjusting plate with one eccentric hole, and the invention adopts the adjusting plate with a plurality of eccentric holes.
