Description
Technical field
The present invention relates to a kind of air suspension apparatus that is used for the vehicle axle suspension, particularly be used for the lift bridge air suspension apparatus of autotruck.
Background technology
Autotruck is generally realized by the quantity that increases vehicle bridge in order to increase its load carrying ability.Increase vehicle bridge and will increase wheel more, when vehicle zero load or underloading, can the wheel tyre wearing and tearing be increased because of the increase wheel increases running resistance.In order to reduce wear on tyres, increase the load carrying ability of vehicle simultaneously, general at present employing is set up and can be promoted the also lift bridge of energy follow-up steering (or claiming floating axle), and realizes by its draft hitch.
Existing autotruck lift bridge draft hitch mostly is an air suspension apparatus, the bearing spring of this device is an air bag, air bag bears vertical load, and the moment that longitudinal force that produces between vehicle body and the vehicle bridge and side force and braking produce is to be born by the guiding mechanism of draft hitch.The guiding mechanism of existing autotruck lift bridge air suspension apparatus is the cantilever beam structure of the single-point location of having only lift arm.It is better that this structure is born the effect of longitudinal force and moment, but the effect of bearing side force is not very good, when vehicle ' turns to, the vehicle front-wheel produces steering torque, vehicle begins to turn to, at this moment, produce turning to the side force of lift bridge by ground, this moment, its lateral rigidity was not enough owing to have only the suspension of the single-point location of lift arm, and vehicle bridge will produce side travel and make the tire side travel, this not only increases the wheel tyre wearing and tearing, lost simultaneously and turned to propulsive effort (side force), made the follow-up steering disabler, influenced the overall performance and the service property (quality) of vehicle.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of air suspension device of vehicle takeup bridge with stop gear at the deficiency of above-mentioned prior art existence, strengthen the lateral rigidity of suspension, so that vehicle ' is when turning to, improve the follow-up steering ability of follow-up steering lift bridge, and alleviate the wheel tyre wearing and tearing.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Comprise lift bridge 5 and carrying air bag 6, lift bridge links to each other by the lower end of comprehensive support 4 with the carrying air bag, carrying air bag upper end is connected with vehicle frame 10 by upper bracket 7, the front side of comprehensive support and lift arm 3 one ends are hinged, warp is hinged with lifting air-bag support 2 in the middle of the lift arm, the other end joins with the lower end that promotes air bag 1, its difference is to be provided with the spacing connecting rod mechanism of side direction at the rear side of carrying air bag and comprehensive support, the front end of the spacing connecting rod mechanism of side direction and comprehensive support 4 are hinged, and the rear end links to each other with vehicle frame 10.
Press such scheme, the spacing connecting rod mechanism of described side direction comprises connecting rod 8 and the connecting rod rack 9 that connects firmly with vehicle frame, the two ends of connecting rod are hinged with comprehensive support and connecting rod rack horizontal (level) respectively, have the hinged hinged or flexible hinged of an end at least, constitute the spacing connecting rod mechanism of single link type side direction thus for slippage.
Press such scheme, the spacing connecting rod mechanism of described side direction comprises hinged double link 14 and the connecting rod rack 9 that connects firmly with vehicle frame, the two ends of hinged double link are hinged with comprehensive support and connecting rod rack horizontal (level) respectively, constitute the spacing connecting rod mechanism of double link type side direction thus.
Beneficial effect of the present invention is by set up the spacing connecting rod mechanism of side direction in the lift bridge air suspension of follow-up steering, the spacing connecting rod mechanism of side direction is made up of connecting rod and connecting rod rack, one end of connecting rod is fixed on the vehicle frame by connecting rod rack, and the other end is connected with the comprehensive support of carrying under the air bag.The spacing connecting rod mechanism of side direction, comprehensive support, lift arm are formed the guide piece of two point locations longitudinally, can bear longitudinal force and side force and various moment between vehicle body and the vehicle bridge.When vehicle when driving process turns to, owing to set up the spacing connecting rod mechanism of side direction, connecting rod and lift arm can swing up and down, therefore suspension about vehicle frame is done relatively with move longitudinally, side-sway then is restricted and retrains, make original cantilever beam structure air suspension become stressed good simple beam structure, the lateral rigidity of whole suspension increases, thereby the lift bridge that is installed under the comprehensive support can not produce side travel, thereby overcome the side force that vehicle produces, increased the follow-up steering ability of lift bridge, this has not only alleviated the wearing and tearing of wheel tyre, and effectively improved the stability of vehicle ', the overall performance of vehicle and service property (quality) are improved.The present invention is simple in structure, and productive costs is low, is convenient to implement, and also is convenient to reequip on existing load-carrying vehicle.
