Abstract

The utility model relates to an automobile suspension system, in particular to a double-rear axle air suspension applied on the vehicle drove under different road conditions for reducing vibration effectively, which comprises a distance rod connecting a frame and a driving axle, characterized in an air bag carrier arranged on the automobile driving axle, and an air spring arranged between the frame and the air bag carrier. The utility model has the advantages of good vibration reducing performance so as to increase the automobile service life, reduce the automobile maintenance and repair cost, increase the driving comfort, enlarge the goods delivering scope and reduce the damage of goods to make the vehicle drive on more types of road surface.

Description

Two back axle air suspensions
(1) technical field under
The utility model relates to automobile suspension system, and particularly a kind of automobile is at the effective two back axle air suspensions of vibration damping of various road travelings.
(2) background technology
Existing pair of back axle truck all is steel spring formula balance suspension basically, during running car, the road surface acts on the vertical reaction impact often on the wheel, and when particularly running at high speed on the very poor road surface of road conditions, this impulsive force will reach very big numerical value.Impulsive force passes to vehicle frame and vehicle body, can cause the infantile failure of automobile parts, and goods also can cause damage owing to jolting, and also can make the occupant feel extremely uncomfortable.Theory and practice proves, guarantee that vehicle has good riding comfort, must consider at first that suspension gear can make the natural frequency of body vibrations enough low, and amplitude is enough little, and common leaf spring suspension frame structure is unfavorable for ride comfort.
(3) summary of the invention
The utility model provides a kind of two back axle air suspensions that can effectively reduce body vibrations frequency and amplitude when running car in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Of the present utility model pair of back axle air suspension comprises the propelling rod that is connected between vehicle frame and the drive axle, and its special character is: also comprise the air bag carriage that is fixed on the automobile drive axle, be fixed on the air bellow between vehicle frame and the air bag carriage; Be fixed with vertical track bar bracket and stabilizer rod carriage on the vehicle frame, be connected with a longitudinal rod between vertical track bar bracket and the air bag carriage, be connected with balance folder and Panhard rod between stabilizer rod carriage and the air bag carriage.
Of the present utility model pair of back axle air suspension also is connected with shock absorber between vehicle frame and air bag carriage, play auxiliary damping of vibrations.
Of the present utility model pair of back axle air suspension, the end of described propelling rod is hinged on respectively on vehicle frame and the drive axle.
Of the present utility model pair of back axle air suspension, described propelling rod are the V-arrangement propelling rod.
Of the present utility model pair of back axle air suspension, when vehicle ' produced vibration, along with the increase of vibrational load, air bellow was compressed, and the spring height reduces, and the spring intracavity volume reduces, and load-carrying capacity increases, and spring stiffness increases; On the contrary, when vibrational load reduced, the air bellow height raise, and the spring intracavity volume increases, and load-carrying capacity reduces, and spring stiffness also reduces relatively.Like this, in the effective travel of air bellow, the height of air bellow, chamber internal volume, load-carrying capacity will change along with the increase and decrease generation pulsation-free of vibrational load, periodic flexibility, thereby realize effective control of flexibility transmission, amplitude and the vibrational load of bearing capacity.
Of the present utility model pair of back axle air suspension utilizes pressurized air to make the air bellow pressurising.Postpone before the vertical propelling rod arrangement and draw, better the biography of realizable force connects.Air bellow adopts big span symmetric arrangement, and air bag carriage horizontal positioned is used for supporting and being connected each parts.Adopt the large diameter Panhard rod of big span, make vehicle have very strong anti-roll capability.
The utlity model has the favorable damping effect, vehicle is provided a kind of support of air-cushion type, effectively reduce the vibrations under vehicle zero load and the load, thereby reduce injury, can prolong the vehicle operation life-span the automobile and the person, reduce the M R expense of automobile, improve the comfort level of driving, reduce fatigue, increase the scope of shipping goods, reduction makes vehicle be suitable for more multichannel face to the infringement of goods.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 vertical track bar bracket, 2 longitudinal rods, drive axle in 3,4 air bag carriages, 5 Panhard rods, 6 balance clamp assemblies, 7 stabilizer rod carriages, 8 air bellows, 9 vehicle frames, 10 shock absorbers, 11 Connection Blocks, 12V shape propelling rod, 13V shape propelling rod bearing, 14 rear driving axles.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Of the present utility model pair of back axle air suspension comprises the V-arrangement propelling rod 12 that is connected between vehicle frame 9 and the drive axle, is connected air bag carriage 4 on the automobile drive axle, is connected air bellow 8 and shock absorber 10 between vehicle frame 9 and the air bag carriage 4; Be fixed with vertical track bar bracket 1 and stabilizer rod carriage 7 on the vehicle frame 9, be connected with a longitudinal rod 2 between vertical track bar bracket 1 and the air bag carriage 4, be connected with balance folder 6 and Panhard rod 5 between stabilizer rod carriage and the air bag carriage 4.The end of V-arrangement propelling rod 12 is hinged on vehicle frame 9 and the drive axle by V-arrangement propelling rod bearing 13 and Connection Block 11 respectively.Shock absorber 10 adopts the beidirectional hydraulic pressure cylinder type damper of lower limit mode.
Of the present utility model pair of back axle air suspension when being used for three trucies, adopts the trailing arm four-bar linkage structure, on middle drive axle 3 and rear driving axle 14 this suspension system is installed all.Horizontal orientation device is realized by the layout of V-type propelling rod 12, is flexible connection mode with vehicle frame 9 and vehicle bridge bonded assembly hinge-point.Point of connection on vehicle frame 9 is an attachment point with V-arrangement propelling rod bearing 13 and vertical track bar bracket 1, and parallelogram law is followed in the motion of vehicle bridge.Utilize air bellow 8 to realize effective control of flexibility transmission, amplitude and the vibrational load of bearing capacity.10 auxiliary damping of vibrationss of shock absorber.Postpone before longitudinal rod 2 arrangements and draw, realized that better the biography of power connects.
