Abstract
The utility model which relates to a vehicle part is an on-board air hanging device for heavy truck and tractor and includes: two bending arm beams; air spring devices are arranged on the bending arm beams; limitation shake-absorption devices are arranged on the bending arm beam; the air springs are connected with height valves through tubes; the height valves are connected to electro-magnetic valve through tubes; upward push rods are arranged on the bending arm beams; one end of the upward push valves is connected with supports, and the frame is connected with the push rod. The utility model is applicable for heavy trucks and tractors that have an axle load of 13,000 kg and a standard width of 2,500 mm which can meet the frame height regulation. The utility has simple structure and even stress and can reduce road damages caused by heavy trucks thereby decreasing the maintenance cost of freeway.
Description
Technical field
The utility model relates to automobile component, is a kind of Vehicular air suspension gear that is mainly used in heavy wrecker truck and tractor truck.
Background technology
For safety and the traveling comfort that improves automobile, extensive used for installing air suspension device on passenger and freight car, this air suspension apparatus, can't be installed on heavy motor vehicle and the tractor truck and use, because the destructiveness of heavy-load automobile road pavement is bigger, therefore, how to design the air suspension system that is suitable for using on the heavy-load automobile, most important for the service expenditure that reduces ground-surface degree of tortuosity, reduction express highway pavement.
Summary of the invention
The purpose of this utility model is, a kind of Vehicular air suspension gear is provided, mainly be applicable to axle load 13000kg, normal width 2500mm and can satisfy heavy-load automobile and the tractor truck use that chassis frame height is regulated, rational in infrastructure, stress equalization, can reduce the destruction of heavy-load automobile road pavement, and then the service expenditure of reduction express highway etc.
The utility model for achieving the above object, be achieved through the following technical solutions: the Vehicular air suspension gear, comprise two bent arm beams, air bellow is installed on the bent arm beam, and position-limited shock absorber is installed on the bent arm beam, and air bellow is connected with levelling valve by pipeline, levelling valve is connected with electromagnetic valve by pipeline, lower thrust rod is installed on the bent arm beam, and lower thrust rod one end is connected with support, and vehicle frame is connected with propelling rod.Bent arm beam is connected with stabilizer antiroll bar.Position-limited shock absorber is the hydraulic stop shock absorber, and 2 hydraulic stop shock absorbers are installed on the bent arm beam.Described bent arm beam is a C shape.Propelling rod has two bars, an end of the two bars composition V-type that is connected, and two of lower thrust rods are formed the parallelogram guide piece with propelling rod.
Advantage of the present utility model is: it can be applicable to heavy-load automobile and tractor truck, is specially adapted to axle load 13000kg, width 2500mm, heavy-load automobile that wheelbase is less and tractor truck.The ride comfort and the stability of running car have greatly been improved, fundamentally improved ride of vehicle, compactness rational in infrastructure, stress equalization, reduced the live load of wheel, minimizing by a relatively large margin the degree of tortuosity of vehicle road pavement, thereby reduced express highway pavement service expenditure etc.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is that the utility model is installed in the structural representation on the automobile; Accompanying drawing 3 is plan structure scheme drawings of accompanying drawing 2.
The specific embodiment
The contrast drawings and Examples are described further the utility model:
1 is bent arm beam among the figure, air bellow 2 is installed on the bent arm beam 1, position-limited shock absorber 4 is installed on the bent arm beam 1, air bellow 2 is connected with levelling valve 7 by pipeline, levelling valve 7 is connected with electromagnetic valve 5 by pipeline 3, lower thrust rod 10 is installed on the bent arm beam 1, and lower thrust rod 10 1 ends are connected with support 8, and vehicle frame is connected with propelling rod 9.Bent arm beam 1 is connected with stabilizer antiroll bar 6.Position-limited shock absorber 4 is hydraulic stop shock absorbers, and 2 hydraulic stop shock absorbers 4 are installed on the bent arm beam 1.Described bent arm beam 1 is a C shape.Propelling rod 9 has two bars, an end of the two bars composition V-type that is connected, and 10 two of lower thrust rods are formed the parallelogram guide piecees with propelling rod 9.The utility model is installed on the automobile when using, Fig. 2, shown in 3, bent arm beam 1 adopts bolt, pressing plate 13 is fixed on the vehicle bridge 11 of automobile, 4 air bellows 2 are installed in 4 end points of two bent arm beams 1 respectively, form high stability support platform, vertical load is all born by the air bag on the air bellow 2, two levelling valves 7 are controlled 4 air bellows 2 respectively, when vehicle bridge 11 is beated when reaching a certain height, levelling valve 7 starts the switch of porting, and the air bag on the air bellow 2 is charged and discharged gas, to reach the height of regulating air bellow 2, make it under any load, keep certain operating altitude, make chassis frame height not influenced by load.Levelling valve 7 has aie escape valve, by being connected to the electromagnetic valve 5 in the pipeline 14, to reach artificial control to levelling valve 7, satisfies the needs that chassis frame height is regulated.Position-limited shock absorber 4 tops connect to ground by bolt, and the bottom is fixed on the bent arm beam 1, make vibration damping to improve vehicle running smoothness.An end was connected on the vehicle bridge 11 after propelling rod 9 connected into V-type, two ends connect to ground by propelling rod bearing 12 in addition, bear the suffered transverse load of vehicle bridge 11, prevent that vehicle bridge 11 from producing side travel, the V-type of propelling rod 9 and following two propelling rods 10 are formed parallel-crank mechanism, and lower thrust rod 10 1 ends are connected with bent arm beam 1, one end is connected with support 8, only make motion of translation when making the drive axle vibration, do not produce and reverse, bear all longitudinal forces, side force and the moment thereof of vehicle frame and wheel simultaneously.One end of stabilizer antiroll bar 6 connects to ground, and the other end is connected with bent arm beam, to reduce body roll, improves car load and turns stable.
