Abstract
The invention provides a kind of new axle housing backing plate assembly, including axle housing backing plate, axle housing middle piece, limited block, bolt, nut, the axle housing backing plate includes four dentation backing plate matrixes, slotted provided with circular arc the backing plate matrix bottom surface corner, the bolt is U-bolt, the axle housing backing plate is fixed on axle housing middle piece by limited block, and screw bolt and nut cooperation.The axle housing backing plate using limited block add bolt fastening means and axle housing carry out it is spacing couple, instead of traditional welding manner, avoid, because commissure stress concentration causes the bridge hull to break down caused by welding, making the reliability of axle housing get a promotion.
Description
Technical field
The invention belongs to vehicle chassis technology field, and in particular to a kind of new axle housing backing plate assembly.
Background technology
Drive axle housing is one of important spare part on automobile, plays a part of supporting automobile load, and load is passed
Pass wheel.Tractive force, brake force, side force and the vertical force acted in driving moment is also to pass to suspension by axle housing
Or chassis, thus axle housing is both bearing part and force transmission element.It is main reducing gear, differential mechanism and driving moment transmission again simultaneously
The carrier and shell of device.Axle housing backing plate is as the important component that the annex on axle housing is for carrying out suspension positioning connection.
The U of Chinese patent literature CN 202463473 disclose a kind of Drive axle housing, including the axle housing shell with bonnet
Body, the axle housing housing both ends set spindle nose respectively, and left and right installation is respectively equipped with the axle housing housing between two spindle noses and bonnet
Plate, the leaf spring backing plate being engaged with spring block is provided with the inside of the left and right installing plate.The utility model clearly states
Meet under the requirement of performance, realize light-weight design, these parts are by advanced welding procedure in rational welding ginseng
Number is welded on axle housing housing under instructing, and forms axle case assy.
The U of Chinese patent literature CN 203427540 disclose the leaf spring backing plate on a kind of Drive axle housing, including four shapes
Shape identical subpad plate, the above and below of each subpad plate are provided with interconnected mounting hole, one group two-by-two of four sub- backing plates, often
Group is respectively welded at the forward and backward face of Drive axle housing, and the profile of the subpad plate is rectangular, its height and axle housing end height phase
Should, and its middle part is provided with rectangle lightening hole.In that patent, backing plate is fixed on Drive axle housing by welding manner.
Existing axle housing backing plate carries out spacing connection using welding manner mostly, and welding manner easily produces stress collection in commissure
In, axle housing failure is easily caused by larger stress in vehicle traveling process, and then oil leak even the bridge hull to break down is produced, influence
Traffic safety.
The content of the invention
In order to solve the above technical problems, improving the reliability of axle housing, the present invention provides a kind of new axle housing backing plate assembly, should
Axle housing backing plate using limited block add bolt fastening means and axle housing carry out it is spacing couple, instead of traditional welding manner, avoid because
Commissure stress concentration causes the bridge hull to break down caused by welding, the reliability of axle housing is got a promotion.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of new axle housing backing plate assembly, including axle housing backing plate, axle housing middle piece, limited block, bolt, nut, the axle housing backing plate
Including four dentation backing plate matrixes, the backing plate matrix bottom surface corner is slotted provided with circular arc, and the bolt is U-bolt, the bridge
Shell backing plate is fixed on axle housing middle piece by limited block, and screw bolt and nut cooperation.
Further, the U-bolt is slotted axle housing backing plate and axle housing middle piece through the circular arc of backing plate matrix bottom surface side
It is fixedly connected, limited block is fixed on axle housing middle piece by weld seam.
The left and right movement of axle housing backing plate can be so constrained by limited block, and due to axle housing backing plate and limited block
Between without direct rigid connection, it is ensured that the drawing that is subject on axle housing backing plate in vehicle operation, pressure are not transferred to
On limited block and limited block weld seam.The forward and backward of axle housing backing plate is moved through backing plate internal arm and axle housing middle piece cooperation to carry out about
Beam.Axle housing backing plate is fitted by U-bolt fastener guarantee axle housing backing plate bottom surface and axle housing middle piece bottom surface again, so as to limit axle housing
The upper and lower displacement of backing plate.
Further, the limited block is rectangle.
Compared with prior art, beneficial effects of the present invention are：
（1）Optimize the structure of axle housing backing plate in the present invention, coordinate limited block to couple with axle housing middle piece, eliminate axle housing backing plate with
The joining weld seam of axle housing middle piece so that drawing that axle housing backing plate is subject in vehicle operation, pressure are not transferred to weld seam
On, cause the situation that axle housing is torn or weld seam is torn to occur so as to avoid commissure stress concentration.
（2）The present invention adds the mode that bolt fastens to carry out spacing connection to axle housing backing plate advantageous by limited block, cancels
Backing plate is fixed on axle housing by welding manner, avoid because stress concentration caused by commissure cause in vehicle traveling process by
To larger stress, and then cause axle housing to fail, lift the reliability of axle housing.

Embodiment
With reference to embodiment, the present invention is described in further detail.
Fig. 1 and 2 is axle housing backing plate assembly diagram of the present invention.As illustrated in fig. 1 and 2, a kind of new axle housing backing plate assembly, bag
Include axle housing backing plate 1, axle housing middle piece 2, limited block 3, bolt 4, nut 5.Fig. 3 and 4 is the structural representation of axle housing backing plate of the present invention.
As shown in Fig. 3 and 4, the axle housing backing plate 1 includes four dentation backing plate matrixes 11, and the bottom surface corner of backing plate matrix 11 is provided with circular arc
Fluting 12, the bolt 4 are U-bolt, and the axle housing backing plate 1 is fixed on bridge by limited block 3, and bolt 4 and the cooperation of nut 5
On shell stage casing 2.
Particularly, the U-bolt through the circular arc fluting 12 of the bottom surface side of backing plate matrix 11 by axle housing backing plate 1 and bridge
Shell stage casing 2 is fixedly connected, and limited block 3 is fixed on axle housing middle piece 2 by weld seam.
It can so constrain the left and right movement of axle housing backing plate 1 by limited block 3, and due to axle housing backing plate 1 and spacing
Without direct rigid connection between block 3, it is ensured that the drawing that is subject on axle housing backing plate 1 in vehicle operation, pressure will not pass
It is delivered on limited block 3 and the weld seam of limited block 3.The forward and backward of axle housing backing plate 1 is moved through the internal arm of axle housing backing plate 1 and axle housing middle piece 2
Coordinate to enter row constraint.Axle housing backing plate 1 passes through the bottom surface of 5 fastener guarantee axle housing backing plate of U-bolt 1 and the bottom surface phase of axle housing middle piece 2 again
Fitting, so as to limit the upper and lower displacement of axle housing backing plate 1.
In the present embodiment, the limited block 3 is rectangle.
Rectangle limited block 3 can also be arranged on the outside both sides of the tooth of backing plate matrix 11 4.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
