Abstract
The utility model provides a primary and secondary steel plate spring assembly which comprises a primary steel plate spring and a secondary steel plate spring. A steel plate spring base plate is arranged between the primary steel plate spring and the secondary steel plate spring, and the primary and secondary steel plate spring assembly is characterized in that the steel plate spring base plate structurally comprises a supporting panel, the supporting panel extends upwards to form a secondary steel plate spring positioning groove, and the supporting panel extends downwards to form a primary steel plate spring positioning groove. The supporting panel, the secondary steel plate spring positioning groove and the primary steel plate spring positioning groove form an integrated structure. The two planes of the supporting panel are in contact with the primary steel plate spring and the auxiliary steel plate spring respectively, the secondary steel plate spring positioning groove clamps the secondary steel plate spring in the width direction, the primary steel plate spring positioning groove clamps the width direction of the primary steel plate spring, and therefore the positioning between the primary steel plate spring and the secondary steel plate spring in the vertical direction is ensured. According to the primary and secondary steel plate spring assembly, due to the fact that the structure of the steel plate spring base plate is improved, displacement during the using process is avoided, and the purpose that the secondary steel plate spring does not interfere with a frame and tyres is achieved.
Description
Technical field
The utility model belongs to automobile suspension system field, relates to major-minor steel plate spring assembly.
Background technique
Current commercial car, when assembling major-minor steel plate spring assembly, between main steel plate spring and auxiliary spring, adopt plane steel plate spring cushion block, when encapsulation main steel plate spring and auxiliary spring, use U bolt fastening to it, because there is gap in 2 U bolts self, adding in the vertical direction does not have spacing, thereby make in the vertical direction between main steel plate spring and auxiliary spring exist certain displacement, when automobile is crossed roughness pavement, left, right leaf spring unbalance stress, can cause displacement increasing, occur after this situation, auxiliary spring not only can be interfered with tire, and can interfere with vehicle frame.
Summary of the invention
For fear of in the vertical direction between main steel plate spring and auxiliary spring, there is no the spacing defect that causes displacement in using process, reach the object that auxiliary spring is not interfered with vehicle frame and tire, the utility model proposes a kind of major-minor steel plate spring assembly.
For dealing with problems, the utility model is by the following technical solutions: a kind of major-minor steel plate spring assembly, comprise main steel plate spring, auxiliary spring, between main steel plate spring and auxiliary spring, be provided with leaf spring backing plate, main steel plate spring, auxiliary spring, leaf spring backing plate is provided with bolt through hole, auxiliary spring, between leaf spring backing plate and main steel plate spring, be bolted, the structure that it is characterized in that leaf spring backing plate: there is a support plate, support plate extends upward an auxiliary spring locating slot, support plate is extended a main steel plate spring locating slot downwards, described support plate, auxiliary spring locating slot and main steel plate spring locating slot form overall structure, two planes of support plate contact with main steel plate spring, auxiliary spring respectively, auxiliary spring locating slot blocks the width direction of auxiliary spring, main steel plate spring locating slot blocks the width direction of main steel plate spring, thereby guarantees the location of in the vertical direction between main steel plate spring and auxiliary spring.
Beneficial effect: the utility model is by improving the structure of leaf spring backing plate, between assurance main steel plate spring and auxiliary spring, in the vertical direction is spacing, avoid the displacement in using process, reach the object that auxiliary spring is not interfered with vehicle frame and tire completely.

Fig. 3 is the plan view of the utility model light plate spring backing plate.
Embodiment
A kind of major-minor steel plate spring assembly as shown in Figure 1, comprise main steel plate spring 1, auxiliary spring 3, between main steel plate spring and auxiliary spring, be provided with leaf spring backing plate 2, main steel plate spring, auxiliary spring, leaf spring backing plate are provided with bolt through hole, fixing by the first bolt 4 between main steel plate spring and leaf spring backing plate, fixing by the second bolt 5 between auxiliary spring and leaf spring backing plate.
As shown in Figure 1, between main steel plate spring 1, leaf spring backing plate 2, auxiliary spring 3, by two bolts, fix.Be not limited to this, also can adopt a bolt that three is fixed together.
As shown in Figure 2 and Figure 3, the structure of leaf spring backing plate: have a support plate 2a, the two ends of support plate 2a extend upward two the arm 2b in place, thereby extend upward an auxiliary spring locating slot 2c; The two ends of support plate 2a extend upward two the arm 2d in place, thereby extend a main steel plate spring locating slot 2e downwards; Described support plate 2a, auxiliary spring locating slot 2c and main steel plate spring locating slot 2e form overall structure; Two planes of support plate 2a contact with main steel plate spring, auxiliary spring respectively, auxiliary spring locating slot 2c blocks the width direction of auxiliary spring, main steel plate spring locating slot 2e blocks the width direction of main steel plate spring, thereby guarantees the location of in the vertical direction between main steel plate spring and auxiliary spring; Support plate 2a is provided with bolt through hole 2f.
As shown in Figure 2, the cross section of leaf spring backing plate 2 is " I-shaped ".
Innovation of the present utility model: by improving the structure of leaf spring backing plate 2, reach the spacing of in the vertical direction between main steel plate spring and auxiliary spring.
Claims (2)
1. a major-minor steel plate spring assembly, comprise main steel plate spring, auxiliary spring, between main steel plate spring and auxiliary spring, be provided with leaf spring backing plate, main steel plate spring, auxiliary spring, leaf spring backing plate are provided with bolt through hole, between auxiliary spring, leaf spring backing plate and main steel plate spring, be bolted, the structure that it is characterized in that leaf spring backing plate: there is a support plate, support plate extends upward an auxiliary spring locating slot, and support plate is extended a main steel plate spring locating slot downwards; Described support plate, auxiliary spring locating slot and main steel plate spring locating slot form overall structure; Two planes of support plate contact with main steel plate spring, auxiliary spring respectively, auxiliary spring locating slot blocks the width direction of auxiliary spring, main steel plate spring locating slot blocks the width direction of main steel plate spring, thereby guarantees the location of in the vertical direction between main steel plate spring and auxiliary spring.
2. a kind of major-minor steel plate spring assembly according to claim 1, is characterized in that: the cross section of described leaf spring backing plate is " I-shaped ".
