Abstract
The utility model discloses an air suspension for lifting and supporting bridge, which comprises one lifting bridge, two lifting air bags which can be inflated and deflated, and two bearing air bags which can be inflated and deflated. The main feature of the utility model: a supporting bridge is lifted and lowered by the buckling and compression of the air spring on the air suspension; when a vehicle runs with no load and with half load, the supporting bridge is lifted off the ground to reduce resistance and obtain the purposes of saving fuel, reducing tire wear, extending service life and saving operation cost; when a vehicle is loaded, the supporting bridge is lowered, which effectively enhances loading capacity of the vehicle and reasonably adjusts axle load distribution and solves overload problem of the vehicle and ensures safe handling of vehicles and roads and bridges. The utility model not only can reduce tire wear, but also can reduce oil wear. The utility model brings its user better economic benefit under the precondition of observing traffic regulations.
Description
(1) technical field
The utility model relates to the suspension system of automotive use, belongs to the air suspension of automobile technical field.
(2) background technology
Constantly perfect along with developing of automobile industry and arteries of communication, high-grade commercial vehicle/comm..vehicle demand is increasing.After new vehicle axle loaden mass limit value transportation industry standard is put into effect, the ubiquitous overload behavior of domestic goods carrying vehicle will be curbed, and it is lower to use the vehicle axle loaden mass limit value of leaf spring suspension system more widely at present.
(3) summary of the invention
The problem that the utility model will be separated provides a kind of as the promoted supporting bridge air suspension supplemental support axle, that can improve vehicle axle loaden mass limit value.
In order to solve the problems of the technologies described above, the utlity model has a lift bridge, two Lifting air sac and two the carrying air bags that can inflate venting that can inflate venting.
Each Lifting air sac is fixed by upper thrust rod band Lifting air sac bracket assembly and lower thrust rod band Lifting air sac bracket assembly, on, the two ends of lower thrust rod band Lifting air sac bracket assembly respectively with propelling rod before end support and air bag undersetting hinged, constitute quadrangular mechanism, air bag undersetting top fixed an above-mentioned carrying air bag, in succession above the carrying air bag and carry air bag upper cover plate component, two covers are by an aforesaid quadrangular mechanism, the device of a carrying air bag and a carrying air bag upper cover plate component composition is arranged in the same way, and by end support before two propelling rods and two carrying air bag upper cover plate component be fixed on vehicle frame below, lift bridge is fixed on the below of two air bag undersettings, the below of vehicle frame both sides is being fixed one by the limiting stopper support respectively and is being used for limiting the limiting stopper of journey of slipping a line on the lift bridge, Lifting air sac has and is used for limiting the bump rubber of journey of slipping a line under the lift bridge, and end supports connect by connecting crossbeam before two propelling rods.
Above-mentioned quadrangular mechanism is a parallel-crank mechanism.
The gentle capsule undersetting of end support is integral cast steel spare before the above-mentioned propelling rod.
The utility model modular design can be used on the vehicles such as 6 * 4 or 8 * 4, all can realize promoting under various operating modes; Principal feature of the present utility model is to be to support bridge to realize promoting and landing by expansion of the air bellow on the air suspension and compression, vehicle is unloaded and when moving semi-load, the supporting bridge promotes built on stilts, reduce resistance, reach fuel-economizing and reduce wear on tyres, increase the service life, save the purpose of Operating Expenses; During vehicle load, the landing of supporting bridge, actv. improves the vehicle load-carrying capacity, rationally adjusts distribution of axle load, has solved the overload problems of vehicle, and guarantees that vehicle, road and bridge security use; The utility model both can reduce Tyte Wear, reduced oil consumption again, brought better economic benefit to the user satisfying under the prerequisite of traffic law.
(4) description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the birds-eye view of figure one.
Wherein: 1, connect crossbeam, 2, end support before the propelling rod, 3, upper thrust rod band Lifting air sac bracket assembly, 4, lower thrust rod band Lifting air sac bracket assembly, 5, Lifting air sac, 6, air bag undersetting, 7, the limiting stopper support, 8, limiting stopper, 9, carrying air bag upper cover plate component, 10, carrying air bag, 11, lift bridge, 12, vehicle frame.
(5) specific embodiment
Promoted supporting bridge air suspension as shown in Figure 1 and Figure 2 comprises that a lift bridge 11, two can inflate Lifting air sac 5 and two the carrying air bags 10 that can inflate venting of venting; Each Lifting air sac 5 is fixing by upper thrust rod band Lifting air sac bracket assembly 3 and lower thrust rod band Lifting air sac bracket assembly 4, on, lower thrust rod band Lifting air sac bracket assembly 3,4 two ends respectively with propelling rod before end support 2 and air bag undersetting 6 hinged, constitute parallel-crank mechanism, end support 2 and air bag undersetting 6 are integral cast steel spare before the propelling rod, air bag undersetting 6 top fixed an above-mentioned carrying air bag 10, in succession above the carrying air bag 10 and carry air bag upper cover plate component 9, two covers are by an aforesaid parallel-crank mechanism, the device of a carrying air bag 10 and carrying air bag upper cover plate component 9 compositions is arranged in the same way, and be fixed on below the vehicle frame 12 by end support 2 before two propelling rods and two carrying air bag upper cover plate components 9, lift bridge 11 is fixed on the below of two air bag undersettings 6, a limiting stopper 8 is being fixed by limiting stopper support 7 respectively in the below of vehicle frame 12 both sides, have bump rubber on the Lifting air sac 5, limiting stopper 8 is used for limiting the journey of slipping a line on the lift bridge 11, bump rubber is used for limiting 11 times journeys of slipping a line of lift bridge, and end support 2 connects by connecting crossbeam 1 before two propelling rods.
When lift bridge 11 needed to promote, Lifting air sac 5 expanded and inflates, the 10 compression venting of carrying air bag, lower thrust rod band Lifting air sac bracket assembly 3,4 swing on the parallel-crank mechanism drives air bag undersetting 6 lift bridge 11 of ining succession and promotes, and rises to certain position, limiting stopper 8 is spacing, and lifting stops; When lift bridge 11 needs landing, carrying air bag 10 expands and inflates, Lifting air sac 5 compression venting, lower thrust rod band Lifting air sac bracket assembly 3 and 4 swings on the parallel-crank mechanism, drive air bag undersetting 6 lift bridge 11 landing of ining succession, drop to certain position, the spacing landing of bump rubber in lifting 0 air bag 5 stops.
