Abstract
The invention provides a main and auxiliary leaf spring assembly which comprises a main leaf spring and an auxiliary leaf spring, wherein a leaf spring bearing plate is arranged between the main leaf spring and the auxiliary leaf spring. The technical points lie in the following structure of the leaf spring bearing plate: the leaf spring bearing plate is provided with a support flat plate, and the support flat plate extends upwards to form an auxiliary leaf spring positioning groove and extend downwards to form a main leaf spring positioning groove; the support flat plate, the auxiliary leaf spring positioning groove and the main leaf spring positioning groove adopt an integral structure; the two plane surfaces of the support flat plate are respectively contacted with the main leaf spring and the auxiliary leaf spring, the auxiliary leaf spring positioning groove is used for clamping the width direction of the auxiliary leaf spring, and the main leaf spring positioning groove is used for clamping the width direction of the main leaf spring, so that vertical positioning of the main leaf spring and the auxiliary leaf spring is guaranteed. Through improvement on the structure of the leaf spring bearing plate, displacement during the use process is avoided, and the purpose that the auxiliary leaf spring doesn't interfere with a vehicle frame and a tire is completely achieved.
Description
Technical field
The invention belongs to the automobile suspension system field, relate to the major-minor steel plate spring assembly.
Background technique
Current commercial car, when assembling major-minor steel plate spring assembly, adopt plane steel plate spring cushion block between main steel plate spring and auxiliary spring, 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, after this situation occurring, auxiliary spring not only can be interfered with tire, and can interfere with vehicle frame.
Summary of the invention
There is no the spacing defect that causes displacement in using process for fear of in the vertical direction between main steel plate spring and auxiliary spring, reach the purpose that auxiliary spring is not interfered with vehicle frame and tire, the present invention proposes a kind of major-minor steel plate spring assembly.
For dealing with problems, the present invention is by the following technical solutions: a kind of major-minor steel plate spring assembly, comprise the main steel plate spring, auxiliary spring, be provided with the leaf spring backing plate between main steel plate spring and auxiliary spring, the main steel plate spring, auxiliary spring, the 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 the 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, the 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 present invention is by improving the structure of leaf spring backing plate, guarantees the spacing of in the vertical direction between main steel plate spring and auxiliary spring, avoids the displacement in using process, reaches the purpose that auxiliary spring is not interfered with vehicle frame and tire fully.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan view of light plate spring backing plate of the present invention.
Fig. 3 is the plan view of light plate spring backing plate of the present invention.
Embodiment
A kind of major-minor steel plate spring assembly as shown in Figure 1, comprise main steel plate spring 1, auxiliary spring 3, be provided with leaf spring backing plate 2 between main steel plate spring and auxiliary spring, 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 the 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 invention: 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, be provided with the leaf spring backing plate between main steel plate spring and auxiliary spring, 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 the 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, the 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, it is characterized in that: the cross section of described leaf spring backing plate is " I-shaped ".
