Description
Technical field
The present invention relates to a kind of special car body frame structure for automotive, more particularly to the small-sized school bus vehicle frame that a kind of suitable rural area, private kindergarten are suitable for.
Background technology
Big multiplex other cars of country's school bus and minibus were alternative in the past, and price is high, and technical matters is lack of standardization, does not embody the Compulsory Feature of school bus, and security is poor.
After country puts into effect school bus new standard, these school buses can not be reused.Used as the cooperation supplier on Chinese school bus chassis, we strive making a economic and practical type school bus vehicle frame, there is provided give car load producer, production allows Chinese most of kindergartens all can afford, school bus.According to the situation of market survey, Product Design Orientation in small-sized child and the school bus of pupils of 10 to 18.
The content of the invention
Cost is produced to save, it is ensured that chassis member assembling is reliable, improve the economic serviceability and security performance of school bus, the present invention proposes the small-sized school bus vehicle frame that a kind of suitable rural area, private kindergarten are suitable for.
For this purpose, the technical scheme is that：A kind of small-sized school bus vehicle frame, including left and right longeron and the crossbeam between left and right longeron, it is characterised in that：The left and right longeron is straight-through beam, and the crossbeam includes forward and backward crossbeam and intermediate transverse girder, and intermediate transverse girder is pipe beam, has been respectively fixedly connected with a buckle support at pipe beam two ends；During assembling, two buckle supports are separately mounted to the inner side of left and right longeron, form local strengthening area, and the two ends of pipe beam are fixedly connected with left and right longeron again, so that pipe beam is held together with left and right longeron；Pipe clamp and chassis member fixed mount are fixedly connected with pipe beam directly.
For one kind of above-mentioned technical proposal is improved by：The buckle support includes pipe beam installing plate, and the flange being connected with left longeron or right vertical beam is integrally extended in the both sides of pipe beam installing plate, is respectively equipped with installing hole on the flange being connected in pipe beam installing plate and with left and right longeron.
For one kind of above-mentioned technical proposal is improved by：The chassis member fixed mount is engine rear suspension, drop hanger, rear shock absorber upper bracket.
For further improvement is that for above-mentioned technical proposal：Engine front support, front stabilizer support are connected with left and right longeron by buckle support, are easy to pipeline to arrange.
For another of above-mentioned technical proposal is improved by：Forward and backward bridge plate spring bracket adopts small-scale structure foundry goods, not only ensure that the stability of part status but also had alleviated weight.
Beneficial effect：
Two longerons are adopted straight-through beam, light and handy easy processing by the present invention；Buckle support is fixedly connected at pipe beam two ends by elder generation, two buckle supports and two longerons are directly connected to, pipe beam two ends and two longerons are fixedly connected as into an entirety again, both crossbeam matching requirements had been met, make again on longeron, to form the closing box of local, the effect of reinforcement is played, the rigid requirements on chassis is met, is mitigated chassis weight with this, while making chassis more firmly meet the requirement of car load comfortableness；Direct Duct fixing clamp, simple and fast on pipe beam, make pipeline arrangement more rationally, reliable, the direct fixed underpan part fixed mount on pipe beam, it is to avoid other punching and machining support, processing cost is reduced with this.The vehicle frame reliability is high, and easy processing effectively reduces integral vehicle cost, economic and practical, is mainly used in the small-sized school bus of 10～18.

Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of small-sized school bus vehicle frame, including left longeron 1, right vertical beam 2 and the crossbeam between left longeron 1 and right vertical beam 2；The left longeron 1, right vertical beam 2 are straight-through beam, and the crossbeam includes forward and backward crossbeam and intermediate transverse girder, by forward and backward riveting transverse beam between left and right longeron；The intermediate transverse girder is pipe beam 3, is respectively welded a buckle support 4 at the two ends of pipe beam 3；During assembling, two buckle supports are first separately mounted to into the inner side of left longeron 1, right vertical beam 2, make on left and right longeron, to form a local strengthening area a respectively, then the two ends of pipe beam 3 are welded with left longeron 1, right vertical beam 2 again respectively, so that pipe beam is held together with left and right longeron；Some pipe clamps are welded with pipe beam 3 directly, simple and fast makes pipeline arrangement more reasonable, reliable, processing cost is reduced, so as to reduce the cost of car load, while, chassis member fixed mount is directly welded with pipe beam 3 also, it is not necessary to punched in addition and machining support.
As shown in Fig. 4, Fig. 5, Fig. 7, Fig. 8, Fig. 9, for a kind of structure of buckle support 4, including pipe beam installing plate 41, the flange 42 being connected with left longeron or right vertical beam is integrally extended in the upper and lower both sides of pipe beam installing plate 41, and installing hole 43 and installing hole 44 are respectively equipped with the flange 42 being connected in pipe beam installing plate 41 and with left and right longeron.
As shown in Fig. 1, Fig. 8, Fig. 9, the chassis member fixed mount is engine rear suspension, drop hanger 5, rear shock absorber upper bracket 6.
As shown in fig. 6, for the structural representation of engine support installation site, during assembling, engine front support is connected with left and right longeron by buckle support；In the same manner front stabilizer support is connected with left and right longeron also by buckle support, is arranged in order to pipeline.
As shown in Figure 1, Figure 2, Figure 3 shows, during assembling, front axle plate spring fore-stock 7, front axle plate spring after-poppet 8, back axle plate spring front bracket 9 and back axle leaf spring after-poppet 10 are adopted small-scale structure foundry goods, the stability of part status had not only been ensure that but also had been alleviated weight.
Two longerons are adopted straight-through beam, light and handy easy processing by the present invention；Buckle support is fixedly connected at pipe beam two ends by elder generation, two buckle supports and two longerons are directly connected to, pipe beam two ends and two longerons are fixedly connected as into an entirety again, both crossbeam matching requirements had been met, make again on longeron, to form the closing box of local, the effect of reinforcement is played, the rigid requirements on chassis is met, is mitigated chassis weight with this, while making chassis more firmly meet the requirement of car load comfortableness；Direct Duct fixing clamp, simple and fast on pipe beam, make pipeline arrangement more rationally, reliable, the direct fixed underpan part fixed mount on pipe beam, it is to avoid other punching and machining support, processing cost is reduced with this.The vehicle frame reliability is high, and easy processing effectively reduces integral vehicle cost, economic and practical, is mainly used in the small-sized school bus of 10～18.
