Description
Technical field:
The utility model relates to the load assembly in a kind of passenger vehicle four gasbags air suspension, is specifically related to a kind of passenger vehicle air suspension whole punch forming C of steel plate shape carriage.
Background technology:
Along with the fast development of China's bus industry and parts technology thereof, also progressively improve the requirement of passenger vehicle traveling comfort in market.The passenger vehicle that adopts air suspension has obtained the approval of home market with its distinctive superior comfort property.The air suspension structure that is fit to China's service condition is produced in research and development, and it is more and more urgent to seem.The air suspension structure that present domestic passenger vehicle is commonly used is six air bag arrangement structures of the first two back four, by the rectangular layout of four gasbags behind the C shape carriage, to support vehicle body.C shape carriage (also claiming shoulder pole girder, C shape arm etc.) is a most important load assembly in the whole rear suspension.
At present, the shaping structures mode of domestic C shape carriage mainly contains inblock cast, steel plate welding and three kinds of molding modes of the whole hot bending of rectangle section bar.
C shape carriage integral body reaches about 1500mm, and about wide 500mm, profile is bigger.If adopt the inblock cast structure, carriage single-piece quality will reach about 160Kg, and this will seriously increase the deadweight of vehicle, and too high dead weight of vehicle will influence the dynamic property of passenger vehicle, increase oil consumption, increase operation cost, not meet the demand for development of energy-saving and emission-reduction.In addition, too high carriage quality makes the unsprung weight of suspension increase, and has reduced the comfort property of car load.And be easy to generate sand holes, internal defect such as loose during the big cast casting of shape, all than higher, manufacturing cost is higher to casting and the requirement of machine up aspect.Another is the C shape carriage of welded-steel plate construction commonly used now, and the single-piece quality is about 120Kg.And complex structure, the welding difficulty is bigger, and weld strength is difficult for guaranteeing, and the welding back is because the scale error accumulative total that weld seam causes makes that the overall dimensions of C shape carriage all is difficult for guaranteeing.In existing three kinds of C shape carrier structures, the C shape carriage situation of the whole hot bending structure of rectangle section bar is better, but it also exists volume and the bigger shortcoming of quality.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of passenger vehicle air suspension whole punch forming C of steel plate shape carriage, it is that bracket body with C shape carriage is divided into the identical two parts of up-down structure, balanced welding is connected into an integral bracket body then, while integrated bumper mounting hole and air bag mounting hole on bracket body, with bracket body fixing on, integrated levelling valve erection support and propelling rod erection support on the lower platen, thereby reduce the volume of C shape carriage as much as possible, volume is little in light weight, low manufacturing cost, high setting accuracy, safe and reliable, comformability is strong, makes easily and installs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of passenger vehicle air suspension whole punch forming C of steel plate shape carriage, it comprises bracket body, top board and lower platen, top board is fixed on the end face of bracket body, lower platen is fixed on the bottom surface of bracket body, be provided with supporting sleeve between top board and the lower platen, top board is provided with the levelling valve erection support, wherein: described bracket body comprises first part and second part, first part is identical with second part structure, first part and second part strike out respectively after the arc, interfix " mouth " font, and the interface of first part and second part is provided with brace panel; All be integrated with the propelling rod erection support on described top board and the lower platen.
Further, described bracket body is provided with bumper mounting hole and air bag mounting hole.
Further, be provided with dowel hole on described top board and the lower platen, dowel hole passes from bracket body.
Further, the quantity of described supporting sleeve is at least four, and supporting sleeve passes with lower platen from top board and fixes, and embedded being fixed in the bracket body.
The beneficial effects of the utility model are:
1, simple and reasonable, the intensity height, highly integrated, light weight is installed reliably.
After adopting two block plate punch formings, the main body of the utility model C shape carriage is welded.Steel plate closes solder together through after striking out arc, has increased the intensity of body greatly.Because carriage intensity is enough,, effectively alleviate quality so the carriage overall volume is can design-calculated less.For the space has been abdicated in limited chassis installation.Quality is much smaller than other existing products, only 89.9Kg.Carriage carries out machinework again after moulding, can well guarantee that size is accurate.This bracket design is reasonable, and Highgrade integration, can satisfy vehicle bridge installation, propelling rod installation, and bumper is installed, and air bag is installed and levelling valve is installed.Particularly the installation of propelling rod is simple and reliable, is convenient to installing/dismounting.Be welded with upper and lower pressing plate and sleeve pipe in the carriage stage casing.Top board is processed with high-precision dowel hole to guarantee the suspension setting accuracy.When suspension was installed, clevis bolt passed sleeve pipe, and sleeve pipe plays the guiding supporting role, upper and lower pressing plate indent distortion and cause the tight phenomenon of bolt lock when avoiding binding bolt.
2, low cost of manufacture
Because the body of the utility model C shape carriage adopts integral plate, raw MAT'L is general, can purchase in batches.Carriage itself is highly integrated, has reduced a large amount of annexes.Manufacturing process is uncomplicated, is fit to batch manufacturing, low cost of manufacture.
3, the adaptation of product is good
The utility model C shape carriage top board is installed with back axle and is cooperated, and the dowel hole position can be changed according to the needs of different vehicle bridge with the clevis bolt hole site, and the associated orifices position change that only needs during change to go up lower platen gets final product, and it is convenient to change, and the adaptation of product is strong.
Advantages such as 4, the utility model C shape carriage has light weight, and cost is low, and the intensity height is high integrated, and comformability is strong, simple and reasonable, safe and reliable, be fit to the mass production requirement.Be used for passenger vehicle four gasbags airsuspension system, be better than existing product.
