Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model provides a kind of rail vehicle, anti-side rolling torsion rod (not shown) is installed, resisted
Side rolling torsion rod is arranged in anti-side rolling torsion rod mounting seat, and anti-side rolling torsion rod mounting seat is fixed on car body.
Anti-side rolling torsion rod mounting seat provided by the utility model, including the crossbeam 1 along the elongated setting in width of the carbody direction,
The end at the both ends of crossbeam 1 is respectively welded and fixed a connecting seat 2, and two connecting seats 2 are weldingly fixed on the side bar of car body both sides (in figure
It is not shown) on, anti-side rolling torsion rod is fixedly connected on two connecting seats 2.
Wherein, crossbeam 1 uses shape of the mouth as one speaks beam, can meet the requirement of the intensity, rigidity, fatigue of car body, can reduce weight again.
In order to further improve the overall construction intensity of crossbeam 1 and rigidity, in the present embodiment, the profile height of crossbeam 1 is added, preferably
The profile height of crossbeam 1 is more than or equal to 60mm.Meanwhile in order to be not take up space limited under car, ensureing that floor panel structure is strong
On the premise of degree, crossbeam 1 is corresponded on floor and is open, a part of the crossbeam 1 on profile height is stretched into opening for car body floor
It is intraoral, the crossbeam 1 of about 5mm or so height can such as be stretched into intralamellar part.
In the both ends gap of crossbeam 1, the insertion of connecting seat 2 is so ensureing crossbeam installed in the indentation, there of the end of crossbeam 1
On the premise of 1 structural strength and rigidity, be advantageous to mitigate the weight of crossbeam 1, and the relative space-consuming for reducing connecting seat 2.
Connecting seat 2 and the border of crossbeam 1 of indentation, there are welded to connect, and ensure bonding strength between the two.
Connecting seat 2 uses box body structure, beneficial to realizing lightweight.Connecting seat 2 is by crossbeam connecting portion 2a, side bar connecting portion 2b
And middle torsion bar connecting portion 2c compositions, crossbeam connecting portion 2a, torsion bar connecting portion 2c and side bar connecting portion 2b are stepped successively
Structure, is advantageous to strengthen the strength and stiffness of connecting seat 2, while ensures the bonding strength between connecting seat 2 and crossbeam 1, connects
Mode is more firm.
Side bar connecting portion 2c is the U-shaped opening groove towards side bar direction opening being made up of two side plates, 3, end plates 4
Structure, has connecting portion (not shown) corresponding with opening slot structure on side bar, in connecting portion insertion opening groove welding connect
Connect.Side bar connecting portion 2c structure can increase the bonding area between connecting seat 2 and side bar, improve connecting seat 2 and side bar
Between bonding strength, and then improve anti-side rolling ability, and connected mode is more firm.
Torsion bar connecting portion 2c intracavitary is provided with cushion block 5, and screwed hole is preset with cushion block 5, and cushion block 5 plays the work of nut
With anti-side rolling torsion rod is fixedly connected by screw with cushion block 5, easy for installation, and need not larger installing space.Connected in torsion bar
Portion 2c two sides have square opening, and cushion block 5 is arranged in square opening.Cushion block 5 plays a part of nut, and it is convenient to change, pad
Block 5 is strip, and two cushion blocks 5 are provided with each connecting seat 2, two screwed holes is tapped with advance on each cushion block 5, in spiral shell
After pit is destroyed, it can be achieved to change on the premise of steel construction is not disassembled, there is preferable interchangeability.
Connecting seat 2 use solid forging structure, for forge integral structural member, the welding of connecting seat 2, only with crossbeam 1 and side
Need to weld between beam, effectively reduce the welding capacity of weld seam, so as to avoid the appearance of weld fatigue, there is high intensity
Feature, also solves the problems, such as the stress concentration of connecting seat 2 and anti-side rolling torsion rod junction.
Anti-side rolling torsion rod mounting seat provided by the utility model, while meeting that intensity, rigidity and fatigue require,
