Description
Technical field
The utility model relates to the C shape carriage in a kind of automotive axle air suspension.
Background technology
Along with the fast development of China's automobile and parts technology thereof, adopt passenger vehicle demand on market of air suspension to increase gradually.The air suspension structure that present domestic passenger vehicle is commonly used is six air bag arrangement structures of the first two back four, and back four gasbags is arranged in the outside of vehicle frame, and C shape carriage (also claiming shoulder pole girder, C shape arm etc.) is a most important load assembly in the whole rear suspension.The structure of present domestic C shape carriage mainly contains inblock cast and two kinds of structures of punching press welding, C shape carriage in the disclosed air suspension of Chinese patent ZL200420019766.6 is the inblock cast structure, and disclosed C shape carriage is the punching press welded structure among the Chinese patent ZL200620200045.4.
Because C shape carriage volume is bigger, adopt the carriage single-piece weight of inblock cast structure to be not less than 200Kg, too high weight will influence the dynamic property of passenger vehicle, and be easy to generate sand holes, internal defect such as loose during the big cast casting of shape, so the C shape carriage of inblock cast structure requires all than higher casting and machine up aspect, so that manufacturing cost is higher.
At present, C shape carriage commonly used is the punching press welded structure, and single-piece weight is about 120Kg.Punching press welded structure C shape carriage is at present domestic to mainly contain two kinds: two structure becomes two-piece structure about becoming along the geometric centre longitudinal cutting with cross cut.Sheet is different fully about the C shape carriage of longitudinal cutting formula, will make the above diel of two covers at least; The C shape carriage of cross cut formula, sheet is incomplete same up and down, also need make two cover diels.Upper and lower of cross cut formula C shape carriage is adopted butt welding, in order to improve intensity, is added with upper and lower liner, and upper and lower liner is the reinforcement blanked part approximate but short slightly with upper and lower chip architecture.Because of C shape carriage is a load assembly, the punching press welded structure need make diel and to welding requirements for quality than higher, its manufacturing cost is also than higher.
The utility model content
The purpose of this utility model provides a kind of C shape carriage of automotive axle air suspension, optimizes the structure of existing C shape carriage, solves technical matterss such as the lightweight of C shape carriage, low manufacturing cost.
For achieving the above object, the utility model adopts following technical scheme: the C shape carriage of automotive axle air suspension, comprise c-shaped bracket body, and described bracket body is formed by square-section section bar one bending.
Be installed with the vehicle bridge Connection Block at position, bracket body stage casing.Described vehicle bridge Connection Block comprises that correspondence is fixedly arranged on the upper and lower pressing plate on upper and lower surface, position, bracket body stage casing, four bights of upper and lower pressing plate are connected by four collar supports that are fixedly arranged on the bracket body both side surface respectively, be fixed with brace panel between two sleeve pipes of the every side of bracket body, upper and lower pressing plate is close on the both sides up and down of brace panel.
Top board is provided with vehicle bridge installing and locating pin-and-hole.
Be installed with the propelling rod that traverses bracket body and both sides brace panel at the carriage middle part tapered sleeve is installed.
The bracket body upper surface is being installed with the air bellow mount pad near on the position at two ends.
Bracket body upper surface two ends are provided with the shock absorber mounting hole in the position in the air bellow mount pad outside.
On the position of vehicle bridge Connection Block both sides, be installed with the levelling valve mounting bracket at the bracket body upper surface.
The utility model is compared with existing C shape carriage has following beneficial effect:
1. simple and reasonable, safe and reliable
The utility model is utilized whole square-section section bar and with the heating of rectangle electromagnetic coil, is carried out bending with mould then, the cooling of spraying water subsequently by square-section section bar integrally bending moulding during production; Substantially can not cause the intensity of section bar itself to reduce in forming process, and the sectional dimension distortion is little, compares with the same level C shape carriage of other structures, intensity and precision are higher, factor affecting such as are not welded, and be safe and reliable, suitable requirements of mass production.Set firmly the vehicle bridge Connection Block in the carriage stage casing, and be processed with high-precision vehicle bridge installing and locating pin-and-hole on the pressing plate thereon, guaranteed the setting accuracy of suspension; 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 not tight phenomenon of bolt lock when avoiding binding bolt.After adopting the utility model, shock absorber can be directly installed on the bracket body, does not need the extra soldered damper bracket, and is simple and reasonable, in light weight, and single-piece weight is about 100Kg.
2. low cost of manufacture
Because the utility model adopts the square-section section bar by the electromagnetic coil hot bending, only needs Bending Mould, has saved the very high diel of cost; Shock absorber is to be directly installed on the C shape carriage, does not need the extra soldered damper bracket, has saved damper bracket; Save upper and lower liner of punching structure C shape carriage and strengthened blanked part.The levelling valve mounting bracket is set directly on the bracket body, and is succinct, convenient.
In addition, the utility model C shape carrier structure advantages of simple, anufacturability is good, is fit to product lot quantity production.And because this C shape bracket main body is a section bar, intensity is only relevant with section bar itself, does not have other influence factors, the C shape carriage of relative like this other structures, and product design is also than being easier to control.
3. the adaptation of product is good
The utility model C shape carriage top board cooperates with the installation of vehicle bridge, its dowel hole position can be changed according to the needs of different vehicle bridge with the clevis bolt hole site, 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.
Propelling rod is set in C shape carriage middle part tapered sleeve is installed, be used to assemble straight propelling rod; At C shape carriage two ends shock absorber mounting hole and air bellow mount pad are set, very convenient when general assembly.
