Description
Technical field
The rear-suspension system of car is the utility model is related to, is a kind of torsion being related in rear suspension type in particular
Turn beam.
Background technology
Torsion girder-like rear suspension is due to the advantage such as its weight, cost, installing space, simple in construction, extensive use in recent years
In A0, A level car, small-sized SUV, compact SUV and MPV.
Though torsion girder-like rear suspension is simple in construction, it must complete all functions of automotive suspension, therefore it is reliable resistance to
Seem long even more important.For solve crossbeam in itself, crossbeam and trailing arm welding endurance issues, common practice is exactly to pass through increasing
Add the reinforcing plate between the thick material of crossbeam, increase section of beam, increase crossbeam and trailing arm and improve the fatigability of crossbeam material
Energy.Crossbeam endurance issues are can solve the problem that although so doing, it is likely that can be changed the performance of torsion beam other side and be added
The weight and cost of torsion beam, do not meet the requirement of the benefit of enterprise.
The content of the invention
The purpose of this utility model is to propose the horizontal high torsion beam of a kind of excellent in durability, lightweight.
Two trailing arms that torsion beam of the present utility model includes crossbeam, is welded and fixed respectively with crossbeam left and right ends, trailing arm
Bottom is connected with wheel hub shaft stool and damper bracket, and bushing sleeves are provided with the top of trailing arm；The torsion beam also includes being connected to
Spring tray between crossbeam, trailing arm；Key is that the section of the crossbeam is U-shaped opening section；The both ends of crossbeam are additionally provided with
Reinforcing plate in crossbeam, one end of reinforcing plate is welded and fixed with corresponding trailing arm in the crossbeam, and the other end is extend into crossbeam, and
Fixed with beam welding.
Above-mentioned torsion beam adds Path of Force Transfer, can share horizontal stroke by setting reinforcing plate in crossbeam at the both ends of crossbeam
The carrying of beam and trailing arm weld seam, ensure that crossbeam and trailing arm welding are reliable；Crossbeam torsional rigidity is also add simultaneously, in crossbeam stress
Level can suitably reduce beam thickness when being less than its desired value, and crossbeam weight is reduced with this.
Further, the both sides of the crossbeam are provided with inclined flange, rounding off between the flange and crossbeam；And turn over
The both ends on side transit to plumbness by heeling condition.When by twisting conditions, the edge of its both sides easily crossbeam occurs
Stress concentration, after flange is set in both sides, original high stress is transferred to inside crossbeam by crossbeam edge, improves the crossbeam longevity
Life；Crossbeam torsional rigidity is improved simultaneously, preferable crossbeam torsional rigidity can be obtained with relatively thin beam thickness, and reduce crossbeam
Weight.
Further, the both ends of the crossbeam are provided with the breach being adapted with trailing arm shape, and the trailing arm is stuck in crossbeam end
In the breach in portion, it can so extend beam-end and the welding line length of trailing arm as far as possible so that the weld seam of unit length undertakes
Overcome possible small, so as to improve both connection stability and reliabilities, while trailing arm can also be formed and clamped, avoided
Relatively rotated between trailing arm and crossbeam.
Further, the opening direction of the crossbeam is downward, arranges forward or backward and causes compared to section opening
Torsion beam shear centre it is relatively low the defects of, make rear suspension roll center is relative to improve, effectively improve Ackermann steer angle transition
Turn to the problem of larger, while spring tray and shock absorber can also be arranged together, make overall structure it is compacter, close
Reason.
Further, the both ends of crossbeam are slightly above in the middle part of the crossbeam, with the stress of rigidity equilibrium and beam-end.
Torsion beam of the present utility model is additionally arranged reinforcing plate in crossbeam using the crossbeam that Open Side Down at crossbeam both ends,
So as to effectively improve the connection reliability between the torsional rigidity of torsion beam and crossbeam and trailing arm, and cause torsion beam more
Add lightweight, there is good practicality.

Embodiment
Below against accompanying drawing, by the description to embodiment, to specific embodiment of the present utility model as involved by
The shape of each component, construction, the mutual alignment and annexation between each several part, the effect of each several part and operation principle etc. make
It is further to describe in detail.
Embodiment 1：
As illustrated, two that the torsion beam of the present embodiment includes crossbeam 1, is welded and fixed respectively with the left and right ends of crossbeam 1
Trailing arm 2, the bottom of trailing arm 2 are welded with wheel hub shaft stool 3 and damper bracket 4, and the top of trailing arm 2 is provided with bushing sleeves 5；Should
Torsion beam also includes the spring tray 6 being connected between crossbeam 1, trailing arm 2；The section of the crossbeam 1 is the downward U of opening direction
Shape opening section, the both ends of crossbeam 1 are provided with the breach 11 being adapted with the shape of trailing arm 2, and the trailing arm 2 is stuck in the end of crossbeam 1
In breach 11；The both ends of crossbeam 1 are provided with reinforcing plate 7 in crossbeam, and one end of reinforcing plate 7 is welded with corresponding trailing arm 2 in the crossbeam
Fixation is connect, the other end is extend into crossbeam 1, and is welded and fixed with crossbeam 1.
The middle part of crossbeam 1 is slightly upper to lift, the middle and slow transition in end, so that the middle part of crossbeam 1 is slightly above crossbeam 1
Both ends, with rigidity equilibrium and the stress of the end of crossbeam 1.
The both sides of crossbeam 1 are provided with inclined flange 12, rounding off between the flange 12 and crossbeam 1；And flange 12
Both ends transit to plumbness by heeling condition.For crossbeam 1 when by twisting conditions, easily there is stress in the edge of its both sides
Concentrate, after in both sides, flange 12 is set, by original high stress by the edge transitions of crossbeam 1 to crossbeam 1 inside, improve crossbeam 1
Life-span；The torsional rigidity of crossbeam 1 is improved simultaneously, the preferable torsional rigidity of crossbeam 1 can be obtained with the relatively thin thickness of crossbeam 1, and drop
The low weight of crossbeam 1.
Above-mentioned torsion beam adds Path of Force Transfer, can shared by setting reinforcing plate 7 in crossbeam at the both ends of crossbeam 1
The carrying of crossbeam 1 and the weld seam of trailing arm 2, ensure that crossbeam 1 welds reliably with trailing arm 2；The torsional rigidity of crossbeam 1 is also add simultaneously,
When the stress level of crossbeam 1 is less than its desired value, the thickness of crossbeam 1 can be suitably reduced, the weight of crossbeam 1 is reduced with this.
