Abstract
The utility model discloses a kind of trailer leaf spring bottom plate, belong to trailer field.It includes supporting plate and the holding firmware being fixed on below supporting plate, the corner and center of the supporting plate are respectively equipped with bolt hole, the supporting plate and holding firmware are made of steel plate, and the holding firmware includes two structure identical bending parts, and two bending parts are fixedly connected as frame structure with supporting plate.The utility model, in the case where ensureing that purposes and intensity are not reduced, greatly reduces weight and cost by forming frame structure to steel plate punched, bending, welding, and processing technology is simpler.
Description
Technical field
The utility model belongs to a kind of trailer accessory, specifically, more particularly to a kind of trailer leaf spring bottom plate.
Background technology
It is typically provided between Trailer car shaft and car body on the leaf spring for damping, Trailer car shaft and is welded with leaf spring bottom plate,
Leaf spring bottom plate is provided with bolt hole, and leaf spring is placed on supporting plate, and centre bolt passes through supporting plate centre bolt hole on leaf spring, U-shaped
Leaf spring is fixed locked on axletree by fastening bolt through the bolt hole on supporting plate.At present, existing leaf spring bottom bracket is generally adopted
Processed with casting technique, it has following defect：(1) because foundry industry has greater environmental impacts, cast member is near several
The national supervision energetically to environmental protection over year, therefore production and application is increasingly restricted；(2) cast member easily produces casting and lacked
Fall into, structural strength can not meet use requirement；(3) cast member of same intensity will be weighed relative to the bottom plate weight that steel plate is processed
A lot, weight 3.2KG of cast steel processing or so, the weight of steel plate processing only has 1.55kg, and cast member can not meet trailer light weight
The demand of change.
Utility model content
The utility model purpose is to provide a kind of trailer leaf spring bottom plate, to overcome trailer leaf spring bottom plate in the prior art
Above-mentioned defect caused by being manufactured using cast steel.
The utility model is realized using following technical scheme：A kind of trailer leaf spring bottom plate, including supporting plate and fixation
Holding firmware below supporting plate, the corner and center of the supporting plate are respectively equipped with bolt hole, and the supporting plate and holding firmware use steel
Plate is made, and the holding firmware includes two structure identical bending parts, and two bending parts are fixedly connected as frame structure with supporting plate.
Using welding between the supporting plate and holding firmware.
Using welding between described two bending parts.
One side of the bending part and supporting plate angle are acute angle.
Compared with prior art, the beneficial effects of the utility model are：The utility model by steel plate punched, bending,
Welding forms frame structure, in the case where ensureing that purposes and intensity are not reduced, and greatly reduces weight and cost, and processing
Technique is relative to cast simpler.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is dimensional structure diagram of the present utility model.
In figure：1st, supporting plate；2nd, holding firmware；3rd, bolt hole；4th, bending part.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of trailer leaf spring bottom plate, including supporting plate 1 and the card for being fixedly welded on the lower section of supporting plate 1
Firmware 2, the corner and center of the supporting plate 1 are respectively equipped with bolt hole 3, and the supporting plate 1 and holding firmware 2 are made of steel plate.
The holding firmware 2 includes two structure identical bending parts 4, and bending part 4 is manufactured by punching press, bending, two foldings
Comer pieces 4 is fixed with supporting plate 1 and is welded as frame structure, and a side of bending part 4 and the angle of supporting plate 1 are acute angle, make its structure
It is more stable and firm.
In use, the holding firmware 2 of leaf spring bottom plate is welded on Trailer car shaft, leaf spring is placed on supporting plate 1, on leaf spring
Centre bolt passes through the bolt hole 3 that supporting plate center is passed through after leaf spring, and two U-shaped fastening bolts are across leaf spring and are each passed through supporting plate
On corner on two bolts hole 3, centre bolt and U-shaped fastening bolt all lock are on axletree, so that by leaf spring fixing lock
Extremely on axletree.
