Greatly, and this structure is also easy to produce stress and concentrates, and trailing arm is cracked frequent occurrence in vehicle use process, or even fracture
The case where；Since the assembly space of trailing arm is limited, the trailing arm of muscle structure type is also unfavorable for assembly technology.
Utility model content
Aiming at the above shortcomings existing in the prior art, the purpose of this utility model is to provide a kind of shell mould air suspensions
Trailing arm maintains part key position to solve traditional muscle structural strength, cost and the disadvantage of assembly technology, the structure type
Rigidity uniformity avoids the mutation bring risk of stress concentrations of part transition region rigidity, improves bracket service life；Instead
Actuating rod tightens the spatial design at place into shell mould, is effectively prevented from the problem of trailing arm is interfered with pneumatic impact spanner, is promoted easy to assembly
Property.
The utility model is achieved through the following technical solutions:
A kind of shell mould air suspension trailing arm, by trailing arm pedestal 11, preceding air spring shell mould groove connector 12, rear air bullet
Spring shell mould groove connector 13, the trapezoidal linking arm 14 of back reaction rod and the connection connection of shell 15 of stabilizer bar semicircle form one
Body；
Wherein, the trailing arm pedestal 11 is band there are four the square block of connecting hole, is connect, is held in the palm with vehicle bridge by U bolt
The both ends of arm pedestal 11 are extended respectively at preceding air spring and rear air spring with shell mould groove structure, the shell mould groove
Structure is respectively preceding air spring shell mould groove connector 12 and rear air spring shell mould groove connector 13, rear air spring shell
Type groove connector 13 is equipped with stabilizer bar semicircle and connects shell 15, for connecting stabilizer bar, trailing arm pedestal 11
On be additionally provided with the trapezoidal linking arm 14 of two back reaction rods, the outside and middle part of trailing arm pedestal 11 are located at, for connecting anti-work
Use bar.
Further, on the preceding air spring shell mould groove connector 12 and rear air spring shell mould groove connector 13
It is equipped with five reinforcing ribs.
Further, stabilizer bar semicircle connection shell 15 is semicircular structure.
Compared with prior art, as follows the advantages of the utility model:
1, the shell mould air suspension trailing arm of the utility model, total are designed to shell mould, maintain part key position
Rigidity uniformity, avoid the mutation bring risk of stress concentrations of part transition region rigidity, improve bracket service life；
Back reaction rod tightens the spatial design at place into shell mould, is effectively prevented from the problem of trailing arm is interfered with pneumatic impact spanner, promotes assembly side
Just property；
2, the trailing arm pedestal of the utility model connects back reaction rod；The structure of pedestal to front and back air spring junction is support
The most severe position of arm stress, being easy to produce stress concentration causes trailing arm to be broken, therefore this part-structure entire body is designed to round and smooth
Shell mould groove structure, guarantee the uniformity of its rigidity, stress avoided to concentrate, be in addition the intensity for guaranteeing this part-structure,
Intermediate position increases reinforcing rib；Pedestal and preceding air spring attachment portion, which are integrated under damper, connects point structure, pedestal with
Air spring attachment portion is integrated with stabiliser bar connection structure afterwards.
3, the shell mould air suspension trailing arm of the utility model obtains practical application in tractor, is that complete vehicle structure is reliable
Property, property design requirement easy to assembly provide powerful support；
4, the shell mould air suspension trailing arm of the utility model can make to account in the market using the shell arrangement scheme completely newly developed
10% is reduced according to the air suspension trailing arm weight of leading position；
5, the shell mould air suspension trailing arm of the utility model can make to occupy master in the market while realizing structure lightened
The use reliability for leading the air suspension of status promotes 20%.
6, the shell mould air suspension trailing arm of the utility model to assemble more convenient, and productive temp promotes 50%.
