Description
Technical field
The utility model relates to a kind of upper reinforcement structures for rear torsion beam suspension, and it is semi-independent to belong to automobile rear torsion beam
Suspension technical field.
Background technique
Torsion beam semi-independent suspension is currently used rear overhang hanging hang structure, passes through the V-arrangement or channel section of an entirety
Torsion beam the trailing arm of the left and right sides is welded together, strand formula is made by rubber-metal support and vehicle body in the front end of trailing arm and is connected
It connects, is connected in the rear end of trailing arm with wheel hub, damper and damping spring.The trailing arm of torsion beam can be swung up and down around rigid connection point
Vibration is absorbed will pass through damper and damping spring, plays the role of shock-absorbing, when two sides Suspension Deformation does not wait, torsion beam hair
Raw torsional deflection can play the role of stabilizer bar because the torsion beam has biggish elasticity.Therefore torsion beam is torsion girder-like
Critical component in semi-independent suspension plays the role of power transmission, stress and connection balance two sides, and suspension is related to vehicle behaviour
Control property and comfort.When two sides Suspension Deformation, torsion beam deforms, to torsion beam and trailing arm, drum mounting plate and tire branch
The level weld seam requirement of frame is very high, if being designed bad, it is easy to so that between torsion beam and trailing arm, drum mounting plate and tire support
It cracks, to influence the safety of vehicle.
In torsion beam suspension assembly, torsion beam both ends are welded with trailing arm, and bushing pipe is welded in the front end of trailing arm, and bushing pipe installs rubber
Glue-metal support is connected on vehicle body, and rear end welding vibration damping mounting, shock stop pin and the drum mounting plate of trailing arm are pacified by shock stop pin
Helical spring is filled, vibration damping mounting mounting shock absorber is supported on ground by drum mounting plate fifth wheel hub wheel tire.In the prior art
In, since torsion beam both ends are directly welded on trailing arm, steering situation or uneven road surface are met, commissure stress is all be easy to cause
It is larger, it is cracked so as to cause weld seam.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of upper reinforcement structure for rear torsion beam suspension,
Torsion beam and trailing arm weld stress can be reduced, causes to crack so as to avoid weld stress concentration.
To solve above-mentioned technical problem the technical scheme adopted by the utility model is being used for the upper reinforcement of rear torsion beam suspension
Part structure, including torsion beam, torsion beam both ends are welded with trailing arm, and the front end of trailing arm is welded with bushing pipe, and the rear end of trailing arm is welded with
Vibration damping mounting, shock stop pin and drum mounting plate, the weld of torsion beam both ends and trailing arm are welded with reinforcer, and reinforcer includes the
One reinforcer and the second reinforcer, the first reinforcer are located at top position of the torsion beam towards trailing arm rear end side, and second reinforces
Part is located at bottom position of the torsion beam towards trailing arm rear end side.
Further, drum mounting plate is directly welded on the outer end face of trailing arm rear end, the outer end bending of trailing arm rear end
Setting, and bending direction is adapted with the wheel hub installation direction of drum mounting plate.
Further, drum mounting plate is welded on tire support, tire support is welded on the lateral wall of trailing arm rear end.
The beneficial effects of the utility model are: the weld at torsion beam both ends and trailing arm has increased reinforcer newly, and to adding
Strong part welding position rationally designs, and avoids the stress concentration region of torsion beam and trailing arm, can substantially reduce torsion beam with
The stress of trailing arm welding, to improve the intensity and safety coefficient of torsion beam Yu trailing arm welding position.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of reinforcer in the utility model；
Marked in the figure: 1- torsion beam, 2- trailing arm, 3- bushing pipe, 4- vibration damping mounting, 5- shock stop pin, 6- rouse mounting plate, 7- wheel
Tire bracket, 8- reinforcer, the first reinforcer of 81-, the second reinforcer of 82-.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As depicted in figs. 1 and 2, the utility model includes torsion beam 1, and 1 both ends of torsion beam are welded with trailing arm 2, before trailing arm 2
End is welded with bushing pipe 3, and the rear end of trailing arm 2 is welded with vibration damping mounting 4, shock stop pin 5 and drum mounting plate 6,1 both ends of torsion beam and vertical
The weld of arm 2 is welded with reinforcer 8, and reinforcer 8 includes the first reinforcer 81 and the second reinforcer 82, the first reinforcer 81
In torsion beam 1 towards the top position of 2 rear end side of trailing arm, the second reinforcer 82 is located at torsion beam 1 towards 2 rear end side of trailing arm
Bottom position.When welding reinforcer 8, weld seam is there can be no solder skip, phenomena such as weld seam is not uneven, full, burn-through.Reinforcer
8 design both needs to avoid stress concentration region, avoids the movement interference with vibration damper assembly again.After welding reinforcer 8, each work
Improved strength under condition is obvious, and originally the stress decrease half of trailing arm 2 and 1 junction of torsion beam, maximum decrease by 900MPa.
There are two types of mounting means for drum mounting plate 6: one is drum mounting plates 6 to be directly welded on the outer end face of 2 rear end of trailing arm,
The outer end of 2 rear end of trailing arm is bent setting, and bending direction is adapted with the wheel hub installation direction of drum mounting plate 6.Another kind is
Drum mounting plate 6 is welded on tire support 7, and tire support 7 is welded on the lateral wall of 2 rear end of trailing arm.It is used in the present embodiment
It is second of mounting means.
In the assembling of torsion beam suspension assembly, bushing pipe 3 is installed rubber-metal support and is connected on vehicle body, passes through shock stop pin 5
Helical spring is installed, 4 mounting shock absorber of vibration damping mounting is supported on ground by drum 6 fifth wheel hub wheel tire of mounting plate.
