Description
Technical field
The utility model belongs to auto parts machinery field, and in particular to a kind of high intensity carriage bottom plate.
Background technology
Truck body is provided at automotive back includes base plate, framework and boxboard for containing the casing of goods, truck body,
Three is collectively forming a cavity for holding freight.Wherein, carriage bottom plate plays vital effect in the use of railway carriage,
It is the matrix of whole railway carriage, can support framework and boxboard, carries the weight of goods in whole railway carriage and railway carriage.
Existing carriage bottom plate generally includes one block of solid steel plate, sets many by way of riveting then at the steel plate lower end
, with steel plate of crossbeam be positioned on car body for this when using by root crossbeam, by crossbeam by carriage bottom plate and car body
Connect.However, such structure has the following disadvantages：
1st, steel plate is too heavy, increased the burden of automobile, can not meet the demand now to automotive light weight technology, and if to subtract
The quality of Light steel sheet, only reduces its thickness, but the intensity of so base plate does not reach requirement again；
2nd, crossbeam and steel plate are connected by the way of riveting, when automobile is subject to larger vibration, between steel plate and crossbeam
Displacement is susceptible to, causes to connect unstable between steel plate and crossbeam；
3rd, in assembling motor vehicle, it is necessary to be first connected steel plate with crossbeam, then crossbeam is connected with car body, it is this kind of repeatedly
The mode of connection causes assembly operation to bother.
Utility model content
The utility model is intended to provide a kind of high intensity carriage bottom plate, and the carriage bottom plate light weight, intensity are high, itself connection
Stabilization and car body are simple to operate when assembling.
The utility model provides following base case：A kind of high intensity carriage bottom plate, including base plate body, base plate body bag
Point plate of the polylith in in-line distribution is included, described point of plate is aluminium alloy plate, and point plate includes upper plate and lower plate, between upper plate and lower plate
The gusset of polylith connection upper plate and lower plate is provided with, polylith gusset is collectively forming alveolate texture with upper plate and lower plate；The lower plate
Lower end be provided with crossbeam, crossbeam is aluminum alloy cross beam, and the two ends of crossbeam all extend to the edge of base plate body；In same point plate
Upper plate, lower plate, crossbeam and all gusset one extrusion formings, friction welding (FW) connection between adjacent point plate.
The know-why and technique effect of a kind of high intensity carriage bottom plate of the utility model be：
1st, plate and crossbeam is divided to be aluminum alloy material, i.e., whole carriage bottom plate is aluminum alloy material, compared to steel plate
Speech, the carriage bottom plate of this programme is lighter, can meet the demand now to automotive light weight technology.
2nd, polylith gusset, upper plate and lower plate are collectively forming point plate of alveolate texture, and alveolate texture refers to intensive many
Pore structure, similar to the structure of honeycomb；Under square one, for common solid slab, inside is alveolate texture
Plate intensity is higher, therefore, meet it is light-weighted in the case of, the carriage bottom plate in this programme can also meet intensity requirement high.
3rd, upper plate, lower plate, crossbeam and all gusset one extrusion formings in same point plate, compared in the prior art one
For a little alveolate textures by bonding way formation, the alveolate texture intensity of one extrusion forming is higher；In addition, crossbeam
It is integrally formed with a point plate, for the connected mode compared to existing riveting, it will not send out between the two when by larger vibration
Raw displacement, connected mode is more stable；And when automobile is carried out, without again by connection between base plate body and crossbeam
, directly with car body be connected crossbeam by operation, simplifies assembling process, and assembling is simpler, efficiency high.And prior art
In steel plate and crossbeam between cannot realize one extrusion forming.
4th, base plate body includes polylith point plate, and carriage bottom plate general size is larger, and one extrusion forming difficulty is high, by its point
It is polylith point plate difference one extrusion forming, significantly reduces the difficulty of extrusion forming；Friction welding (FW) connects between adjacent point plate
Connect, for common thermofussion welding, arc-welding, friction welding (FW) loss of strength is small, the defect such as bubble-free, pin hole in its weld seam, weld
Connect intensity good.
The following is the preferred scheme based on above-mentioned base case：
Preferred scheme one：Based on base case, the axis of the crossbeam is vertical with the length direction of above-mentioned in-line.Phase
For being acute angle compared with angle between the two, under vertical distribution relation, the contact point of base plate body and crossbeam is few, and occurring should
The probability that power is concentrated is small；In addition, when carriage bottom plate is extruded by transverse direction, under vertical distribution relation, crossbeam can also for both
Bear certain extruding force.
Preferred scheme two：Based on base case or preferred scheme one, described point of plate is along the width of in-line length direction
180mm, the width of crossbeam is 80mm.Width ratio so is relatively adapted to.
Preferred scheme three：Based on preferred scheme two, the distance between the upper plate and lower plate are 15mm, and the thickness of upper plate is
2-3mm, the thickness of lower plate is 2-3mm, and horizontal depth of beam is 3-5mm.So vertical distance, height or thickness proportion are relatively fitted
Close.
Preferred scheme four：Based on base case, preferred scheme one or three, the honeycomb hole in the alveolate texture is circle
Shape.Simple structure, intensity is high, and bearing capacity is strong.
Preferred scheme five：Based on base case, preferred scheme one or three, the honeycomb hole in the alveolate texture is ellipse
Shape.Simple structure, intensity is high, and bearing capacity is strong.
Preferred scheme six：Based on base case, preferred scheme one or three, the honeycomb hole in the alveolate texture is triangle
Shape.Simple structure, intensity is high, and bearing capacity is strong.
Preferred scheme seven：Based on base case, preferred scheme one or three, the honeycomb hole in the alveolate texture is four sides
Shape.Simple structure, intensity is high, and bearing capacity is strong.
Preferred scheme eight：Based on base case, preferred scheme one or three, the honeycomb hole in the alveolate texture is positive six
