Specific implementation mode
Further details of explanation is done to the present invention With reference to embodiment, it should be appreciated that of the invention
Protection domain be not restricted by specific implementation.
Shown in Fig. 1, for 1 structure of current existing turning support, front truck is welded on by upper ear plate 1-1L and lower ear plate 1-2L
It is simple in structure on the side plate of frame 2M-1, it is light-weight.But in the angle of otic placode and vehicle frame side plane contact(Virtual coil position)Stress
It concentrates seriously, fatigue cracking easily occur in prolonged alternate load effect, side plate and weld seam.
Shown in Fig. 2, the turning support 1 in the present invention exists including bottom plate 11, the protrusion 12 being fixed on bottom plate 11, setting
Lug on protrusion 12, bottom plate 11 are slab construction, are directly connected to front frame 2, protrusion 12 is internally provided with hollow cavity
13,13 one end open of cavity, open end connecting bottom board 11, bottom plate 11, protrusion 12 and lug are an integral molding structure, increase
1 intensity of turning support, bottom plate 11 can also be regarded as to be formed as 12 open end edge bending of protrusion, the trapezoidal structure in open end, no
Only meet the needs of two lugs are not of uniform size, also increase the length of curve of open end edge, reduces the stress of unit area.
Above-mentioned protrusion 12 is designed as hollow structure, and the steering force that hollow structure can carry out the transmission of two lugs is evenly dispersed, avoids answering
Power is concentrated, meanwhile, the structure of boring can also mitigate constant weight.
There are two lug in the present invention is set, respectively first lug 15 and the second lug 16, lug are equipped with for pacifying
The pin hole of pivot pin 5 is filled, two lug pin holes are coaxial, for installing steering cylinder fixed pin shaft.Two lugs are separately fixed at protrusion
12 both sides can set lug to hollow knot to further mitigate the weight of turning support 1 in the case of proof strength
Structure, the hollow cavity 13 of lug are connected with the hollow cavity 13 of protrusion 12 so that stress gradually can disperse and transmit along wall.
Two lugs are arranged at the one end of protrusion 12 far from bottom plate 11.In order to make up, 1 bending edges of turning support are relatively fragile to be lacked
Point, bending part are respectively provided with reinforcing rib 14, and bending part includes the junction of protrusion 12 and pedestal, which increases turning support
1 intensity.
When power is transferred to bottom plate 11 by protrusion 12, and then is transferred to front frame 2 by bottom plate 11, can be held to increase
The area for carrying on a shoulder pole power reduces the stress of unit area, and it is polygon that bottom plate 11, which connect edge with front frame 2, and is in arc per one side
The curve of degree, curve can be irregular, in order to increase the length that bottom plate 11 connect side with front frame 2 as far as possible.
Turning support 1 in the present invention can be evenly dispersed by each side wall of protrusion 12 by stress that lug passes over
It opens, is further transferred to bottom plate 11, by increasing the connection edge lengths of bottom plate 11 and front frame 2, further dispersive stress, this sets
Meter increases the service life of bearing.
As shown in figure 3, when installing the turning support 1 in the present invention, the bottom with turning support 1 is reserved in front frame 2
The groove of 11 border geometric identity of plate is welded and fixed after the bottom plate 11 of turning support 1 is embedded in groove, and groove can be
Bottom plate surrounding side wall is welded and fixed by the through-hole for penetrating front frame foreboard with through-hole wall, and embedded welding increases welding
Intensity, the side plate butt welding of 11 border of bottom plate and front frame 2 of turning support 1, forms complete box-structure.Butt weld
Structure in the inside of weld seam as shown in figure 4, have a composition backing 25, and all butt weld in border requires full penetration,
Weld seam needs seamlessly transit.
Fig. 5-Fig. 7 is the steering coupling mechanism in the present invention, turns to the turning support that coupling mechanism includes fixed front frame 2
1, the steering cylinder 9 of the articulated body 4 of fixed Rear frame 3, connection turning support 1 and articulated body 4, steering cylinder 9 include two, the
One steering cylinder 9 and the second steering cylinder 9, are respectively symmetrically distributed in 2 left and right sides of front frame, and front frame 2 includes opposite up and down
Upper plate 21 and lower plate 22, the opposite left plate 23 in left and right and right panel 24, set that there are four pin holes on articulated body 4, including be used to connect
The upper pin hole of upper plate 21, the lower pin hole for connecting lower plate 22, the left pin hole for connecting steering cylinder 9 and right pin hole, wherein
Upper pin hole and the coaxial arrangement of lower pin hole, likewise, upper plate 21 and lower plate 22 are equipped with pin corresponding with upper pin hole and lower pin hole
Hole passes through pin hole and articulated body 4 of the rotary shaft 10 in the upper pin hole of the pin hole, articulated body 4 that connect on upper plate 21, lower plate 22
Lower pin hole, front frame 2 can rotate around the rotary shaft 10.
It there are two turning support 1 is set, is separately fixed in the left plate 23 and right panel 24 of front frame 2, the first steering cylinder 9 connects
The turning support 1 of left plate 23 and left pin hole are connect, the second steering cylinder 9 connects the turning support 1 of right panel 24 and right pin hole, setting two
A steering cylinder 9 provides steering force, pushes and is mutually rotated between front frame 2 and articulated body 4, finally realizes full-vehicle steering.Two turns
Ensure both sides uniform stressed to oil cylinder 9, improves steering efficiency, while preventing unilateral stress excessive, lead to flimsy problem.
As shown in fig. 7, being connected by axis pin between steering cylinder 9 and turning support 1, the axis pin of the junction is hollow knot
Structure, centre pass through bolt 6, and 6 end side of bolt is limited using cover board 7, fixed using nut 8 after cover board 7, cover board 7 is close to convex
Ear secures the relative position of axis pin and lug, prevents axial shaking.The hollow structure of axis pin is convenient for the dismounting of axis pin simultaneously,
The tool for helping such as drawbench can be used, are inserted into axis pin centre bore 51, axis pin is extracted.
As shown in figure 8, the axis pin of connection turning support 1 and steering cylinder 9 is the multi-diameter shaft of two-part, there is centre bore
51.The butt end of axis pin and the pin shaft hole of upper lug coordinate, in the pin shaft hole of axis pin taper end and lower lug, the bearing of steering cylinder 9
Hole coordinates simultaneously.Upper lug and lower lug are that two lug relative positions on same turning support 1 are gained the name, when installation, two
Lug is arranged up and down.
The preferred embodiment of the present invention is above are only, the present invention is not limited in the content of embodiment.For in this field
