Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further
Detailed description, it is therefore an objective to help those skilled in the art to have completeer to design, the technical scheme of the present invention
Whole, accurate and deep understanding, and contribute to its enforcement.
As shown in figures 1 and 3, the invention provides a kind of towing arm, including towing arm body 2, be arranged at
Lining 1 on towing arm body 2 and the folding being arranged on the side being provided with installing hole 23 of towing arm body 2
The reinforcing plate 3 of crook.For being connected with body of a motor car at lining 1, it is long that lining 1 is installed on towing arm body 2
The one end in degree direction, installing hole 23 is arranged at the other end of towing arm body 2 length direction, installing hole 23
For running through the circular hole of setting along towing arm body 2 thickness direction, it is used for allowing realizing towing arm with other parts even
The bolt connect passes.
Specifically, towing arm body 2 is for using steel plate to be stamped to form, and thickness of slab is generally 5mm.Towing
The trocar sheath of arm body 2 and lining 1 is interference fit, and reinforcing plate 3 is welded to the finger on towing arm body 2
Determine position.
Because the panel beating of towing arm body is thicker, the feature of punching press is limited, if feature too complex, easily makes
Become stamping cracking or punching press residual stress too high, it is impossible to by increase thickness of slab or feature increases towing arm
Bending resistance.The load that towing arm bears mainly has the pulling force along towing arm arranged direction and pressure, then has
Just it is perpendicular to the lateral load of towing arm.Particularly, under some operating mode, towing arm can bear the same of pressure
Time bear lateral load, in this case, the as easy as rolling off a log flexing causing towing arm, bending or fracture occur.
Furthermore, some situation, suspension application of the same race, in different vehicles, owing to carload there occurs change, is dragged
The carrying draging arm strengthens, and can produce high stress concentrations locally by the tapping on towing arm, cause due to height
The cracking of stress generation or fracture.In order to improve the stress of towing arm, by the side at towing arm body 2
On bending part reinforcing plate 3 is set, reinforcing plate 3 can be bent into groove as required, or directly uses vertical metal plate
Gold welds at rigidity weakness.The thickness of reinforcing plate 3 can be according to the weight set of vehicle.Such as vehicle becomes
Change less, in the case of carload increases seldom, bending weak on towing arm body 2 can be used
Place increase reinforcing plate 3, and draw materials can be other processing produce leftover pieces, essentially without increase car load system
The cost made.
As shown in figures 1 and 3, towing arm body 2 includes the first arm 21 and the second arm 22, the first arm
The end of portion 21 and the second arm 22 is that arc transition connects, and lining 1 is arranged on the first arm 21, peace
Dress hole 23 is arranged on the second arm 22, forms bending at arc transition, and reinforcing plate 3 is at arc transition
It is welded to connect with the first arm 21 and the second arm 22.
As it is shown in figure 1, in the present embodiment, the most V-shaped structure of towing arm body 2 entirety, and first
Angle between length direction and the length direction of the second arm 22 of arm 21 is between 0-180 degree.Install
Hole 23 is arranged on the second side 25 of the second arm 22, and the first arm 21 has one and the second side
Face 25 is in conplane first side 24, the first side on the axis of installing hole 23 and the first arm 21
The second side 25 on face 24 and the second arm 22 is perpendicular, the axis of installing hole 23 and the axle of lining 1
Line is parallel and perpendicular with the length direction of the first arm 21 and the second arm 22.
As depicted in figs. 1 and 2, in the present embodiment, reinforcing plate 3 be cross section be the structure of concave shape.Add
Strong plate 3 includes the first plate body the 31, second plate body 32 and the 3rd plate body 33 being sequentially connected with, the first plate body 31
With the 3rd plate body 33 for being oppositely arranged, the second plate body 32 and towing arm body 2 for being oppositely arranged, the first plate
Body 31 and the 3rd plate body 33 are welded to connect with towing arm body 2 at the bending part of towing arm body 2.Specifically
, a part for the first plate body 31 and the 3rd plate body 33 and the first side 24 company of welding of the first arm 21
Connecing, the second side 25 of another part and the second arm 22 is welded to connect.Second plate body 32 and the first arm
21 and second arm 22 parallel, between the second plate body 32 and towing arm body 2, there is a certain distance,
Form a cavity.
As depicted in figs. 1 and 2, as preferably, the first plate body 31 and the 3rd plate body 33 are arc,
First plate body 31 and the axis of the 3rd plate body 33 are paralleled with the axis of installing hole 23 and lining 1, the first plate
Body 31 and the axis of the 3rd plate body 33 axis with the circular arc of towing arm body 2 bending part are paralleled, and
Three's axis is in the same side of reinforcing plate 3.Reinforcing plate 3 connects into one by welding and towing arm body 2
Individual entirety, the shape of reinforcing plate 3 and the mating shapes of towing arm body 2, can be effectively improved towing arm
Anti-flexion capabilities, effectively avoid the problem that in platform truck application process, towing arm easily ftractures or ruptures.
As depicted in figs. 1 and 2, as preferably, the second plate body 32 of reinforcing plate 3 is provided with for allowing system
The dynamic via being drawstring through, this via is the through hole that through-thickness runs through setting on the second plate body 32.
