Description
Technical field
The utility model belongs to commercial vehicle suspension system designs technical field, is particularly suitable for using 4 × 2,6 × 4,6 × 2
A kind of vehicle of the matching leaf spring leading arm air suspension such as lifting bridge, and in particular to leaf spring U bolt clamp system.
Background technique
Leaf spring U bolt clamp system is that the parts such as leaf spring and cushion block are fixed on bridge using U bolt is total
Cheng Shang.The mechanism passes through each mating surface under the action of axial pre tightening force by tightening U bolt generation axial pre tightening force
Frictional force resist the longitudinal force and lateral force that generate in vehicle travel process, guarantee the clamping of leaf spring and axle assembly.
Existing leaf spring U bolt clamp system is primarily present following problems:
1, on bearing lateral force and the biggish vehicle of longitudinal force, U bolt can not be completely secured leaf spring with contact
The clamping of connector.
2, on bearing lateral force and the biggish vehicle of longitudinal force, leaf spring twists around centre bolt to be occurred with bridge
Relative motion causes U bolt and other damage parts, suspension system is caused to fail.
Summary of the invention
The utility model is directed to above-mentioned defect existing in the prior art, provides a kind of leaf spring U bolt clamping
Mechanism effectively prevents leaf spring and twists and bridge generation relative motion around centre bolt, causes U bolt and other zero
The problem of part damages, and suspension system is caused to fail, in conjunction with Figure of description, the technical solution of the utility model is as follows:
A kind of leaf spring U bolt clamp system is the leaf spring that will be superposed from bottom to top by U-bolt 7
Cushion block 5 is welded under lower pallet 1, steel plate spring assembly 2, lower support of shock absorber 3, bridge and axle assembly 4 is fastenedly connected composition, it is described to subtract
Vibration device lower bracket 3 is made of cushion block and linking arm, in the cushion block two sides to having two otic placodes, on the otic placode of every side
It is at least opened respectively there are two threaded hole, auxiliary clamp bolt 6 and threaded hole are cooperatively connected, the end press of auxiliary clamp bolt 6
On the leaf spring lateral surface of steel plate spring assembly 2.
Compared with prior art, the utility model has the beneficial effects that:
The auxiliary clamp described in the utility model for passing through U-bolt and two sides by leaf spring U bolt clamp system
Bolt fastens each components, and steel plate spring assembly will not be reversed around centre bolt, avoids that opposite fortune occurs with axle assembly
It is dynamic to cause to cut U bolt, to ensure that the reliability of entire leaf spring U bolt clamp system connection.
Detailed description of the invention
Fig. 1 is the main view of leaf spring U bolt clamp system described in the utility model；
Fig. 2 is A direction view in Fig. 1；
Fig. 3 is in leaf spring U bolt clamp system described in the utility model, and the three-dimensional structure of lower support of shock absorber is shown
It is intended to.
In figure:
1- leaf spring lower pallet, 2- steel plate spring assembly, 3- lower support of shock absorber, 4- axle assembly,
Cushion block, 6- auxiliary clamp bolt, 7-U type bolt are welded under 5- bridge.
Specific embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of leaf spring U bolt clamp system, by leaf spring
Cushion block 5 is welded under lower pallet 1, steel plate spring assembly 2, lower support of shock absorber 3, bridge and axle assembly 4 is sequentially overlapped sets from bottom to top
It sets, and cushion block 5 will be welded by U-bolt 7 under leaf spring lower pallet 1, steel plate spring assembly 2, lower support of shock absorber 3, bridge
It tightens together with axle assembly 4.
The top of steel plate spring assembly 2 is arranged in the lower support of shock absorber 3, and lower support of shock absorber 3 is by cushion block and connection
The cushion block setting of arm composition, the lower support of shock absorber 3 is being welded between cushion block 5 under steel plate spring assembly 2 and bridge, the vibration damping
The linking arm of device lower bracket 3 is used for hinged with the lower end of integrated damper, wherein in addition to conventional U-bolt above-mentioned clamps
Outside structure, as shown in figure 3, in leaf spring U bolt clamp system described in the utility model, in the lower support of shock absorber 3
Cushion block two sides symmetrically set straight down there are two otic placode, two threaded holes are had on the otic placode of every side, each
Threaded hole one auxiliary clamp bolt 6 of mating connection, the auxiliary clamp bolt 6 is on the outside of otic placode, perpendicular to otic placode and screw thread
Hole is in mating connection, by the way that auxiliary clamp bolt 6 is tightened on the otic placode of lower support of shock absorber 3, the end of auxiliary clamp bolt 6
Portion vertically presses against on the leaf spring lateral surface of steel plate spring assembly 2.
By the fastening of above-mentioned U-bolt 7 and the auxiliary clamp bolt 6 of two sides, the steel plate spring assembly 2 will not center
Bolt torsion avoids causing to cut U bolt with the generation relative motion of axle assembly 4, to ensure that entire leaf spring U-shaped spiral shell
The reliability of bolt clamp system connection.
