Abstract
The utility model discloses a kind of spring piot and rack mounting structures, belong to automobile chassis Leaf Spring Suspension System technical field, including flat spring bracket and leaf spring pin, on the leaf spring pin installation flat spring bracket, it is installed in the threaded hole of flat spring bracket using two lag bolts by the through-hole of leaf spring pin；Ring flange and leaf spring pin ontology are integrally welded, and the diameter of ring flange is greater than the diameter of leaf spring pin ontology and concentric with leaf spring pin ontology.The structure completes the disassembly of leaf spring pin using stay bolt by the threaded hole of leaf spring pin flange, is not necessarily to removal tool special, reduces disassembly difficulty, reduce maintenance cost；Secondly because increasing the contact area of leaf spring pin and flat spring bracket without being axial limiting bolt box on leaf spring pin, effectively reducing the concentrated wear of leaf spring pin；Finally using the axial float of lag bolt limitation leaf spring pin and the rotary motion around own axes, compared with a traditional axial limiting bolt, anti-loose ability is stronger, and reliability is higher.
Description
Technical field
The utility model belongs to automobile chassis Leaf Spring Suspension System technical field, and in particular to a kind of spring piot
And rack mounting structure.
Background technique
Currently, leaf spring is still the elastic element of mainstream in truck chassis suspension system, leaf spring passes through plate
Spring pin is connected with flat spring bracket.In the maintenance process of leaf spring, often occur before front suspension fixing end leaf spring pin due to
Arrangement reason causes its inside to have the assemblies such as radiator, and the leaf spring pin withdrawal space is insufficient, need to be equipped with specific purpose tool and be torn open
It unloads；Simultaneously use such leaf spring mounting structure, be easy to appear plate spring pin roll to limit it is bad and cause leaf spring pin abjection, plate
The failures such as spring pin abrasion.To sum up, there is disassembly inconvenience, axial limiting are bad, easy for traditional leaf spring pin and its mounting structure
The problems such as abrasion.
Utility model content
The purpose of this utility model is that in view of the above defects of the prior art, provide a kind of spring piot and
Rack mounting structure, cancelling traditional leaf spring pin is to tear the reserved internal screw thread of pin device and plate spring pin roll open to caging bolt, can be solved
The certainly axial float and wear problem of the not easy to disassemble and leaf spring pin of leaf spring pin.
The utility model is achieved through the following technical solutions:
A kind of spring piot and rack mounting structure, including flat spring bracket 1, stay bolt 2, lag bolt 3, grease tap 4, plate
Spring pin 5, the leaf spring pin 5 are installed on flat spring bracket 1, and the first threaded hole 1-1 is provided on the flat spring bracket 1, described
Leaf spring pin 5 be welded type forge piece of step type structure, be provided with through-hole 5-3 on leaf spring pin 5, pass through leaf spring pin 5 using two lag bolts 3
Through-hole 5-3 be installed in the first threaded hole 1-1 of flat spring bracket 1, realize to 5 axial float of leaf spring pin and around own axes revolve
The dynamic limitation of transhipment；The leaf spring pin 5 includes ring flange 5-2 and leaf spring pin ontology 5-1, ring flange 5-2 and leaf spring pin ontology
5-1 is integrally welded, and the diameter of ring flange 5-2 is greater than the diameter of leaf spring pin ontology 5-1 and concentric with leaf spring pin ontology 5-1.
Further, the first threaded hole 1-1 is arranged symmetrically on 45 ° of directions of flat spring bracket 1, will not be to leaf spring
The intensity of rack body causes excessive influence.
Further, the center leaf spring pin ontology 5-1 is provided with oil leab, and grease tap 4 is mounted on leaf spring pin ontology
The end 5-1, to realize the lubrication of leaf spring pin.
Further, the second threaded hole 5-4 there are two being also set up on the ring flange 5-2.
In the disassembly process of leaf spring pin 5, the second screw thread of leaf spring pin ring flange 5-2 is tightened against using two stay bolts 2
In the 5-4 of hole, with the continuous screw-in of two stay bolts 2, the first mating surface 1-2 phase of bolt head and flat spring bracket 1 and leaf spring pin 5
Contact continues to screw in stay bolt 2, and leaf spring pin 5 can drive leaf spring by the internal screw thread of the upper second threaded hole 5-4 of its ring flange 5-2
Pin 5 moves out, until leaf spring pin 5 exits completely.
Compared with prior art, as follows the advantages of the utility model:
It is primarily due to its disassembly for using two stay bolts to complete leaf spring pin by the threaded hole of leaf spring pin flange, without special
With extracting tool, disassembly difficulty is reduced, maintenance cost is reduced；Secondly because without being that axial limiting bolt is pre- on leaf spring pin
It boxes out, increases the contact area of leaf spring pin and flat spring bracket, effectively reduce the concentrated wear of leaf spring pin；Finally use two
Lag bolt limits the axial float of leaf spring pin and the rotary motion around own axes, with a traditional axial limiting bolt phase
Than anti-loose ability is stronger, and reliability is higher.

Specific embodiment
The specific embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Embodiment 1:
A kind of spring piot and rack mounting structure, using 5 mating band of welded type ladder-type strap ring flange leaf spring pin
The flat spring bracket 1 of one threaded hole 1-1 is installed on the of flat spring bracket 1 by the through-hole 5-3 of leaf spring pin 5 using two lag bolts 3
In one threaded hole 1-1, realize to 5 axial float of leaf spring pin and around the limitation of own axes rotary motion, in the disassembly of leaf spring pin 5
