Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
As shown in figures 1 and 3, the present invention provides a kind of towing arms, including pull arm body 2, are set to towing arm sheet
The stiffening plate 3 of bushing 1 and the bending part being set on the side equipped with mounting hole 23 of towing arm body 2 on body 2.Bushing 1
For connecting with body of a motor car, bushing 1 is installed on one end of towing 2 length direction of arm body at place, and mounting hole 23 is set to towing
The other end of 2 length direction of arm body, mounting hole 23 is the circular hole along towing 2 thickness direction of arm body through setting, for allowing
The bolt for realizing that towing arm is connect with other components passes through.
Specifically, towing arm body 2 is to be stamped to form using thick steel plate, plate thickness is generally 5mm.Pull 2 He of arm body
The outer tube of bushing 1 is interference fit, and stiffening plate 3 is welded to the specified location on towing arm body 2.
Because the metal plate of towing arm body is thicker, the feature of punching press is limited, if feature too complex, be easy to cause punching press to open
It splits or punching press residual stress is excessively high, the bending resistance of towing arm cannot be increased by increasing plate thickness or feature.Towing arm is held
The load received mainly has the pulling force and pressure along towing arm arranged direction, then has the lateral load for being just perpendicular to towing arm.
Particularly, under some operating conditions, towing arm can bear to bear lateral load while pressure, in this case, be easy to cause to drag
There is bending or fracture in the buckling for draging arm.Furthermore some situations, suspension application of the same race is in different vehicles, due to carload
Changed, the carrying of towing arm increases, can the tapping on towing arm generate the high stress concentrations of part, cause due to
The cracking or fracture that high stress generates.In order to improve the stress of towing arm, pass through the bending part on the side of towing arm body 2
Stiffening plate 3 is set, and stiffening plate 3, which can according to need, is bent into groove, or is directly welded with vertical metal plate in rigidity weakness.Add
The thickness of strong plate 3 can be according to the weight set of vehicle.Such as vehicle variation is smaller, in the case that carload increases seldom,
Stiffening plate 3 can be increased using weak bending part on towing arm body 2, and materials can be the corner that other processing generate
Material not will increase the cost of vehicle manufacture substantially.
As shown in figures 1 and 3, towing arm body 2 includes the first arm 21 and the second arm 22, the first arm 21 and second
The end of arm 22 is arc transition connection, and bushing 1 is set on the first arm 21, and mounting hole 23 is set to the second arm 22
On, bending is formed at arc transition, stiffening plate 3 is welded to connect at arc transition with the first arm 21 and the second arm 22.

The angle between direction and the length direction of the second arm 22 is spent between 0-180 degree.Mounting hole 23 is set to the second arm 22
Second side 25 on, on the first arm 21 have one with second side 25 be in conplane first side 24, installation
The axis in hole 23 and the second side 25 in the first side 24 and the second arm 22 on the first arm 21 are perpendicular, mounting hole 23
Axis it is parallel with the axis of bushing 1 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, stiffening plate 3 is the structure that section is in concave shape.Stiffening plate 3 include according to
The first plate body 31, the second plate body 32 and the third plate body 33 of secondary connection, the first plate body 31 and third plate body 33 are to be oppositely arranged, the
Two plate bodys 32 are to be oppositely arranged with towing arm body 2, the first plate body 31 and third plate body 33 towing arm body 2 bending part with
Arm body 2 is pulled to be welded to connect.Specifically, first side of a part of the first plate body 31 and third plate body 33 and the first arm 21
Face 24 is welded to connect, and 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
It is parallel with the second arm 22, there is a certain distance between the second plate body 32 and towing arm body 2, form a cavity.
As depicted in figs. 1 and 2, preferably, the first plate body 31 and third plate body 33 are arc panel, 31 He of the first plate body
The axis of third plate body 33 is parallel with the axis of mounting hole 23 and bushing 1, and the axis of the first plate body 31 and third plate body 33 is simultaneously
It is parallel with the towing axis of circular arc of 2 bending part of arm body, and three's axis is in the same side of stiffening plate 3.Stiffening plate 3 is logical
It crosses welding and connects into an entirety with towing arm body 2, the shape of stiffening plate 3 matches with the shape for pulling arm body 2, can be with
The anti-flexion capabilities of towing arm are effectively improved, towing arm in platform truck application process is effectively avoided and is easy cracking or fracture
Problem.
As depicted in figs. 1 and 2, preferably, the second plate body 32 of stiffening plate 3 is equipped with for allowing brake pulling wire to pass through
Via hole, the via hole be on the second plate body 32 through-thickness through setting through-hole.
As shown in figure 3, in the present embodiment, the second arm 22 of towing arm body 2 is slightly biased to 21 length of the first arm
The side in direction, so that the angle between the length direction of the first arm 21 and the length direction of the second arm 22 is obtuse angle.Peace
Dress hole 23 is set in the second side 25 of the second arm 22, and the axis and second side 25 of mounting hole 23 are perpendicular.First arm
The end face of first side 24 in portion 21 with one with the axis perpendicular of bushing 1, first side 24 and second side 25 is
Arc transition connection, the angle between first side 24 and second side 25 is obtuse angle.The axis of mounting hole 23 and the second arm
Second side 25 on 22 is perpendicular, and the angle between first side 24 on the axis of mounting hole 23 and the first arm 21 is less than
90 degree.
As shown in Figure 3 and Figure 4, in the present embodiment, a part of stiffening plate 3 and the first side 24 of the first arm 21 are welded
It connects in succession, the second side 25 of another part and the second arm 22 is welded to connect.It is used between stiffening plate 3 and towing arm body 2
Vertical welding has certain bending among stiffening plate 3, plays the role of increasing rigidity.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
