Description

A kind of modular composite bus gusset

Technical field

It the utility model is related to traffic and implement technical field, be a kind of modular composite bus side specifically Enclose.

Background technology

With the high speed development of auto industry, the problems such as energy consumption, exhaust emissions and environmental pollution, is on the rise.According to grinding Study carefully and show, global CO₂The 25% of discharge capacity comes from motor vehicle emission, and that haze is wreaked havoc is Chinese particularly true.National Development and Reform Committee Issue report discloses, and China has 600,000,000 populations and 1/4 national territorial area suffer from immanent haze weather.Therefore, automobile Continuous rise of ownership makes environmental issue heat up again, these all call the Green Development of automobile industry.In energy-saving and emission-reduction Global context under, automotive light weight technology be energy-saving and emission-reduction most directly, most efficient method and approach, there is weight to entire society Want meaning.Data shows that body of a motor car weight institute fuel consumption proportion has reached 70%, therefore when body of a motor car weight is every 1% is reduced, oil consumption is with regard to that can reduce by 0.7%, every 100 kilograms of loss of weight, and fuel consumption per hundred kilometers is with regard to that can reduce 0.3-0.6 liters.

At present, common new energy composite material bus side wall structure is as shown in Figure 1, gusset is foam core composite wood Expect global formation.The advantage of this structure is that light-weight, intensity is high, rigidity is big, number of parts is few, but defect is also very bright It is aobvious：Low production efficiency, batch production mould input is more, different length family car pattern tool input is more, workshop input is big, comprehensive cost Height, be difficult to meet (more than 1000) productions of high-volume.

Based on this, present application is made.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of production efficiency height, mould less investment, Gusset length is adjustable, lower-cost modular composite bus gusset.

The purpose of this utility model is achieved through the following technical solutions：

A kind of modular composite bus gusset, it is characterised in that by front overhang section, middle bay section, rear bay section, rear overhang section Totally four module compositions, each part are assembled into gusset by being spirally connected and being glued Hybrid connections.

Front overhang section is fixed in assembly tooling, is sequentially placed middle bay section, rear bay section, rear overhang section, using positioning finger setting, Locking, and fit structure glue sticking are being attached by bolt at the U-typed flange of side before and after each section, completing gusset assembling.

Further, as preferred：

The gusset inner surface is designed as die face and applies flame-retarded resin curing molding, it is possible to achieve gusset inside gadget Function；The installation function such as pre-embedded steel slab integrated seat, handrail, car door at the same time.It is more highly preferred to, the gusset outer surface also makes Smooth surface is processed into even pressing plate, saves gusset exterior skin；It is at the same time structure of sinking by column design, integrated glass installs work( Can, directly over adhering glass and save glass installation section bar, mitigate car body weight.

The gusset front overhang section and rear bay section are fixed section, the section of foundation for each length series bus.

The middle bay section, rear overhang section are adjustable section, the change section for each length series bus.Mold design is group Molding tool, mould are designed according to 12 meters of gusset, and column quantity and spacing can be adjusted by the position that moves moulds, production Product length can be increased and decreased by the frame that moves moulds, and the platform of 8-12 meters of serial bus can be realized by the conversion of length Change.

The operation principle of the utility model is：Front overhang section is fixed in assembly tooling, is sequentially placed middle bay section, rear deck Section, rear overhang section, using positioning finger setting, are being attached locking, and coordinate knot at the U-typed flange of side before and after each section by bolt Structure glue sticking, avoids stress concentration, completes gusset assembling.If wanting to produce the gusset of different length, can be adjusted when part manufactures Middle bay section, rear overhang section die frame and column relevant position, so as to fulfill the manufacture of 8-12 meters of gussets.The gusset group being completed Part can be bolted on chassis, and Body in white frame is assembled into after being merged front wall frame, rear wall frame and head cover.Treat After the completion of Body in white frame assembling, the system unit such as handrail, seat, car door is bolted on the pre-embedded steel slab on gusset Place.

Compared with prior art, the good effect of the utility model is：

Modular composite bus gusset by carbon, glass mix-froth sandwich " sandwich " composite material curing molding, Technical maturity, is simple to manufacture, and can improve more than 50% compared to global formation gusset production efficiency, greatly improve multiple material car The production efficiency of body.Product corrosion resistance is good, effectively improves vehicle body anti-corrosion ability；Product molding are of good quality, and interchangeability is adapted to well Produce in enormous quantities；Product structure is simple, mould less investment, carries out supporting assembling by 4 kinds of parts, different length gusset can be conllinear Production, effectively improves production efficiency and reduces cost；Since whole gusset is divided into the module of several standards, and each module Between type of attachment it is identical, so if 8 meters of car to be changed to 10 car or 12 meters of car, it is only necessary to increase The length of middle bay section, rear overhang section.It is other to change, it can thus realize quick remodeling.Can directly it replace overall Molding bus gusset, produce in enormous quantities for new energy bus and the high volume applications popularization of multiple material product provide it is new Technological approaches.
