Material.
Existing subway chassis mainly uses metal material, and it is present, and weight is big, and corrosion-resistant, the short grade of service life lacks
Point.And carbon fibre material has specific strength and specific modulus height, product excellent in mechanical performance, safe, the good feature of designability
Each technical field is widely used in, sufficiently meets higher assembly precision requirement.
Material can not only be saved by mitigating vehicle body deadweight, reduce power power consumption, and can reduce vehicle abrasion, and extension makes
With the life-span, huge economic benefit is brought.The weight of general car body bearing structure accounts for the 20%-25% of the total gross weight of vehicle, because
This, loss of weight car body bearing structure has realistic meaning.
The content of the invention
For above-mentioned problem, the utility model aims to provide carbon fiber Subway Body chassis, the Subway Body branch
Frame can improve the intensity of carbon fiber subway chassis, reduce the weight of spool.
To achieve these goals, technical scheme is as follows used by the utility model：
Carbon fiber Subway Body chassis, the vehicle body bottom frame include horizontal bar, upper covering, lower covering and honeycomb interlayer, institute
State lower covering bottom transverse direction and be set up in parallel some horizontal bars, the honeycomb interlayer be located at the upper covering and lower covering it
Between, the horizontal bar is foam sandwich structure.
Preferably, it is glued to walk spool between the upper covering and the lower covering.
Preferably, it is described walk spool be located between the honeycomb interlayer and the lower covering.
Preferably, the upper covering, the lower covering and the horizontal bar use carbon fiber prepreg.
Preferably, the carbon fiber prepreg is the prepreg for having anti-flammability.
The beneficial effects of the utility model are：Compared with prior art, the utility model has following significant effect：
（1）The utility model subway Undercarriage structure, manufacturing cost greatly reduces compared to traditional autoclave molding.
（2）The prepreg that the utility model carbon fiber subway chassis uses is fire-retardant prepreg, substantially increases subway bottom
The security performance of frame.
（3）The cabling pipe that the utility model carbon fiber subway chassis uses has effectiveness.
（4）The utility model carbon fiber subway chassis has high intensity, high-modulus, light-weighted feature.
（5）The utility model carbon fiber subway chassis greatly improves the anti-corrosion capability of subway chassis and using the longevity
Life.
（6）The utility model carbon fiber subway chassis is because it prepares excellent material performance, and structure is reasonable in design, has
Good high temperature resistant, the characteristic of high pressure.
（7）Carbon fiber subway chassis impact resistance of the present utility model and shock resistance resilience ability are strong.
（8）Carbon fiber subway chassis of the present utility model can be widely applied to each technical field.
Brief description of the drawings
Fig. 1 carbon fiber subway Undercarriage structure schematic diagrames.
Fig. 2 is the enlarged drawing of D parts in Fig. 1.
Fig. 3 honeycomb interlayers are with walking spool arrangement schematic diagram top view.
Wherein：1- honeycomb interlayers, the upper coverings of 2-, covering under 3-, 4- horizontal bars, 5- walk spool.
Embodiment
In order that one of ordinary skill in the art is better understood on the technical solution of the utility model, with reference to attached
Figure and embodiment are further described to the technical solution of the utility model.
Embodiment：Referring to the drawings shown in 1-3, carbon fiber Subway Body chassis, the vehicle body bottom frame includes horizontal bar 4, upper illiteracy
Skin 2, lower covering 3 and honeycomb interlayer 1, the lower bottom transverse direction of covering 3 and are set up in parallel some horizontal bars 4, the horizontal bar 4
For groove type structure, foam sandwich layer is machined with the groove type structure, the horizontal bar 4 is U-shaped groove, and U-shaped recessed
Groove both sides are laterally outwardly provided with connection feeler, increase the contact area between horizontal bar 4 and lower covering 3, and then improve solidification and connect
The stability connect；The honeycomb interlayer 1 is located between the upper covering 2 and lower covering 3, and the horizontal bar 4 is foam sandwich structure,
The quantity of horizontal bar 4 is 40, and the upper covering 2, the lower covering 3 and the horizontal bar 4 use carbon fiber prepreg, described
Carbon fiber subway chassis uses OOA technological formings.
In the utility model, between the upper covering 2 and the lower covering 3 be glued walk spool 5, it is described walk spool 5
It is located between the honeycomb interlayer 1 and the lower covering 3, is walking spool 5 and honeycomb interlayer 1, walks spool 5 and upper covering 2, honeycomb
The contact position of interlayer 1 and covering needs filling-foam glue.
The utility model specifically first prepares horizontal bar 4, and then covering 3, the lower paving of covering 3 finish under paving on horizontal bar 4
Afterwards, the curing molding together with lower covering 3 of horizontal bar 4, cabling pipe 5 is then glued on lower covering 3, lays honeycomb, in last paving
Covering 2, the upper paving of covering 2 terminates and then one-step solidification, obtains chassis product, the preparation method advantages of simple, operability
By force, and progressively preparation, progressive principle make it that the chassis quality of preparation is higher, more firm.
Prepreg and glued membrane in the example of the utility model are the common knowledges of those skilled in the art, can be according to reality
