Background technique
Torsion beam assembly plays the role of mainly carrying and transmission force as one of rear overhang system main parts size afterwards,
During vehicle movement, impact force of the rear torsion beam assembly transmitting wheel by ground bears larger change in power transmittance process
Shape.Therefore torsion beam assembly has preferable intensity and performance after needing to guarantee, torsion beam assembly is with higher after guarantee sets
Count service life and higher fatigue endurance performance.By the requirement of previous project experiences and specific project, it is different after torsion beam, trailing arm
The otherness generated with the bridging arrangement of spring holder intensity and endurance quality to rear torsion beam assembly is larger, the design phase this
Place's lap position also tends to the danger position as cracking.Vehicle is when crossing potted road surface, by big ground shock load, power
Transfer route it is main are as follows: ground → tire → tire support → trailing arm → rear torsion beam is reversed in rear torsion beam assembly
When, the active force situation that rear torsion beam assembly is subject to is most severe, is easy to happen the case where cracking even fails.This is solved to ask
Topic, traditional form usually add stiffening plate between rear torsion beam, trailing arm and spring holder, but add stiffening plate and there is increase weight
It measures, need to improve the drawbacks of welding process precision.
Summary of the invention
The purpose of the present invention is to propose to the bridging arrangement of torsion beam, trailing arm and spring holder after a kind of, promoted intensity and
Lightweight can be taken into account while durability.
It is of the present invention it is a kind of after torsion beam, trailing arm and spring holder bridging arrangement, including rear torsion beam and be overlapped on institute
The trailing arm of rear torsion beam end is stated, the corner portion that the rear end of torsion beam and the rear portion of the trailing arm are constituted is provided with bullet
The end of spring disk, the rear torsion beam is equipped with the arc groove of opening outwardly, and a part of the trailing arm and the arc groove are mutually embedding
Merga pass overlaps along the weld seam that the edge of the arc groove extends；The spring holder includes spring mountings, is located at
Rake on front side of the spring mountings and the clinch on front side of the rake, the rake is from rear to forward direction
Upper extension, the outside of the rake are equipped with the second overlap edge, and second overlap edge is in arc line shaped and second overlap edge
Along the circumferentially extending of the trailing arm, second overlap edge is taken by the weld seam extended along second overlap edge with the trailing arm
It is connected together；The clinch is overlapped on one by the weld seam extended along the rear torsion beam length direction and the rear torsion beam
It rises, the outside of the clinch is equipped with the overlap joint trunnion of the end of the protruding torsion beam after described, and the overlap joint trunnion is taken
It connects on the trailing arm.
Further, the rear lateral edge of the clinch is connected with the front side edge of rake edge.
Further, the rear lateral edge of the rake is connected with the front side edge of spring mountings edge.
Further, the spring mountings outer side edges along be equipped with the trailing arm overlapped overlap joint flange.
Further, the inner side edge edge of the spring holder and the rear lateral edge of the spring holder are equipped with reinforcement flange.
Further, the overlap joint trunnion is stacked and is welded on the trailing arm.
The present invention, as reinforcement structure and dispersive stress, is able to ascend intensity and durability by setting overlap joint trunnion,
The increased weight for overlapping trunnion simultaneously is smaller, can take into account lightweight requirements.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
The bridging arrangement of a kind of rear torsion beam, trailing arm and spring holder as shown in Figure 1, including rear torsion beam 1 and overlap joint
The corner portion that trailing arm 2 in rear 1 end of torsion beam, the end of rear torsion beam 1 and the rear portion of trailing arm 2 are constituted is provided with spring holder
3, the end of rear torsion beam 1 is equipped with the arc groove of opening outwardly, a part of trailing arm 2 with the mutually embedding merga pass of arc groove arcuately
The weld seam that the edge of slot extends overlaps, and the edge of arc groove is the first overlap edge 7；Spring holder 3 includes spring mountings
4, the clinch 6 positioned at the rake 5 of 4 front side of spring mountings and positioned at 5 front side of rake, rake 5 is from rear to forward direction
Upper extension, the outside of rake 5 are equipped with the second overlap edge 8, and the second overlap edge 8 is in arc line shaped and the second overlap edge 8 is along trailing arm 2
Circumferentially extending, the second overlap edge 8 are overlapped by the weld seam extended along the second overlap edge 8 with trailing arm 2, outside rake 5
Side is along as the second overlap edge 8；Clinch 6 is overlapped by the weld seam extended along rear 1 length direction of torsion beam and rear torsion beam 1
Together, preferably, the front side edge of clinch 6 overlaps along by weld seam with rear torsion beam 1, the outside of clinch 6
The root of overlap joint trunnion 9 equipped with the protruding end in rear torsion beam 1, trunnion 9 is connected with the outer side edges of clinch 6 edge,
Overlap joint trunnion 9 is overlapped on trailing arm 2, and overlap joint trunnion 9 can be overlapped on trailing arm by the weld seam extended along the edge for overlapping trunnion 9
On 2, specifically, overlap joint trunnion 9 is stacked and is welded on trailing arm 2.By above-mentioned overlap joint trunnion 9 being arranged as reinforcement structure,
Setting overlaps trunnion 9 and each weld seam is rationally arranged, and can disperse the stress of each weld seam, be proved by comparative test, Neng Gouti
Intensity and durability are risen, does not need stiffening plate is separately provided and is just able to satisfy use demand, due to overlapping the increased weight of trunnion 9
It is smaller, lightweight requirements can be taken into account.
Specifically, the rear lateral edge of clinch 6 is connected with the front side edge of rake 5 edge.Further, the rear side of rake 5
Edge is with the front side edge of spring mountings 4 along being connected, and for spring mountings 4 for spring after installing, spring holder 3 can be punched
