Description
Technical field
The utility model belongs to heavy motor vehicle mounting bracket technical field, is specifically related to a kind of air chamber support assembly.
Background technology
At present, the brake system of generally installing on cross-country car mostly is air braking system, and air braking system has simple in structure, the advantages such as corrosion, clamping stagnation can not occur.The principle of work of air braking system is: during braking, Pneumatic pipe cleaner in the source of the gas is crossed pipeline system and is delivered in the compressed air brake cylinder that is installed on the air chamber support, by the compressed air brake cylinder effect air pressure is converted to kinetic energy, the motion of promotion braking adjusting arm, the straight-line motion of braking adjusting arm again actuating cam axle rotates, contact thereby brake shoe brake cheek is opened with brake wheel, reach the braking purpose; During brake off, the gas in the compressed air brake cylinder is directly discharged, the brake shoe brake cheek playback.Can find out from System Working Principle, the major tasks position of this air braking system is compressed air brake cylinder, it is bearing the effect that system's air pressure is converted into kinetic energy, so the air chamber support installation bearing piece of compressed air brake cylinder still not, also bears the braking reaction thrust in the work.
Because existing air braking system all uses on the light-duty vehicle chassis without wheel reduction gear, its air chamber support is installed on the vehicle bridge of wheel inboard, gives simultaneously strong point of camshaft, makes camshaft can bear enough large thrust and does not deform.But extra heavy off road vehicle is owing to the steered wheel of having installed with wheel reduction gear, cause wheel diameter and width (directly being reflected on wheel rim and the tyre width) to increase considerably, the mounting means of existing air braking system can't adapt to the structure of heavy-duty off-road vehicle.In the extra heavy off road vehicle field, independent suspension system especially is installed, is adopted the breakaway-element steeraxle and with the extra heavy off road vehicle chassis of wheel reduction gear, because structural restriction, generally adopt at present oil-gas brake mode, the conversion of namely carrying out by air pressure control and oil pressure reaches the purpose of braking.The problem that single this oil-the gas brake mode exists is to have a large amount of easy oil leakages position in the system, and vital parts brake cylinder easy-to-rust, clamping stagnation in the system, thereby can cause the work of brake system unreliable.For adapting to the development in market, to meet customer need, the reliability of motor vehicle braking system in urgent need to be improved need to be used air braking system at Off-road vehicle and extra heavy off road vehicle chassis.Therefore how the air braking system on the Light-duty Vehicle is transplanted to the installation independent suspension system, is adopted a difficult problem that has become technical development on breakaway-element bridge and the extra heavy off road vehicle with wheel reduction gear.
The utility model content
The purpose of this utility model provides a kind of air chamber support assembly that air braking system can be installed on the extra heavy off road vehicle.
The technical scheme that the utility model adopts is:
A kind of air chamber support assembly, comprise camshaft assembly, also comprise steering swivel framework, air chamber support and spindle arm, described steering swivel framework one end is the boss form, and described boss is described to form groove with steering swivel framework body, has through hole on the described groove, described camshaft assembly is installed in the described through hole, the side of described air chamber support is positioning end, and the positioning end of described air chamber support is connected with the boss of described steering swivel framework, and described spindle arm is connected with the positioning end of described air chamber support.
Further, described through hole is in the upper right side of described groove.
Preferably, described air chamber support is the bending body mechanism.
More preferably, the positioning end of described air chamber support is L shaped.
Further, between the positioning end inboard of the fixed end of described air chamber support below and air chamber support reinforced rib is installed.
Preferably, the quantity of described reinforced rib is two.
Further, the positioning end of described air chamber support is captiveed joint with the boss of described steering swivel framework by bolt with described spindle arm.
The utlity model has following having a few:
This apparatus structure is simple, utilize its rational structure, air chamber in the air braking system is installed in rational position, thereby makes air braking system also can be applied to installing independent suspension system, adopt on breakaway-element bridge and the extra heavy off road vehicle and other vehicle with wheel reduction gear.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is described in further detail.
The structural representation of a kind of air chamber support assembly that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
The structural representation of air chamber support in a kind of air chamber support assembly that Fig. 3 provides for the utility model embodiment;
The structural representation of steering swivel framework in a kind of air chamber support assembly that Fig. 4 provides for the utility model embodiment.
The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of air chamber support assembly comprises steering swivel framework 2, air chamber support 1 and spindle arm 16.Steering swivel framework 2 one ends are boss 7 forms, and boss 7 forms groove 11 with steering swivel framework 2 bodies 10.Described groove has through hole 12 on 11 upper right side, and the camshaft assembly 13 in the air chamber 8 is installed in the through hole 12.Air chamber support 1 is the bending body mechanism, and the side of air chamber support 1 is positioning end 3, is shaped as L shapedly, and positioning end 3 upper folding surfaces of air chamber support 1 have the rigidity that the first tapped bore 5, the first tapped bore 5 help to increase air chamber support 1.The upper end of air chamber support 1 is fixed end 4, and air chamber 8 is fixed on the fixed end 4 of air chamber support 1.The positioning end 3 of air chamber support 1 has the second tapped bore 6, have the 3rd tapped bore 9 on the boss 7 of steering swivel framework 2, have the 4th tapped bore on the spindle arm 16, bolt 14 passes the second corresponding tapped bore 6, the 3rd tapped bore 9 and the 4th tapped bore, the positioning end 3 of spindle arm 16 and air chamber support 1 is captiveed joint with the boss 7 of steering swivel framework 2, so just greatly saved the installing space of this device.Between fixed end 4 belows of air chamber support 1 and positioning end 3 inboards of air chamber support 1 two reinforced ribs 15 are installed, reinforced rib 15 helps to increase the intensity of air chamber support 1.
This apparatus structure is simple, utilize its rational structure, air chamber 8 in the air braking system is installed in rational position, thereby makes air braking system also can be applied to installing independent suspension system, adopt on breakaway-element bridge and the extra heavy off road vehicle and other vehicle with wheel reduction gear.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
