Abstract
The utility model relates to an air suspension of a lift bridge, which comprises air bags, brackets, single trailing arms, a cross beam, a lift bag, lever arms, lift rods and shock absorbers, wherein the air bags are respectively arranged at the two sides of an axle, one ends of the single trailing arms are fixed on the axle, and the other ends thereof are connected with the cross beam; and the lift bag is fixed on the cross beam and is connected with the lift rod fixed on the axel, and the lift rod can be lifted by the lift bag when needed to drive the axel and tyres to be at a height above the ground. The upper ends of the air bags are respectively fixed on a frame, and the air bags automatically extend and retract by adjusting the amount of air in the bags so as to achieve the purpose of adjusting the height of the axel, thereby not only reducing the wear of the wheel tyres, but also effectively improving the running stability of a vehicle, and improving the overall performance and use quality of the vehicle.
Description
Technical field
The utility model relates to a kind of lift bridge air suspension apparatus, is used to improve road holding.
Background technology
The air suspension principle of work forms pressurized air with air compressor exactly, and pressurized air is delivered in the energy chamber of spring and shock absorber, changes the height of vehicle with this.Be provided with the overall height sensor near front-wheel and trailing wheel, by the overall height signal of sensor, microcomputer is judged the variation of bodywork height, controls compressor and blow off valve again, makes length of spring compressed or elongation, thereby plays the effect of vibration damping.Air suspension has given automobile more intelligence.When your suspension when running at high speed can hardening improves the stability of vehicle body; And long-time when the road traveling of low speed injustice, control unit can make the suspension deliquescing improve the traveling comfort of car.
The content of air suspension control comprises three of bodywork height, shock absorber attenuation power, the elastic coefficients etc. in general:
1. the control of overall height: branch standard, rising and three kinds of the trailing wheels of only raising;
2. the control of the attenuation power of shock absorber divides basic, normal, high three retainings;
3. the elasticity modulus of air bellow divides soft, hard two retainings.
The exercise performance characteristics of air bellow are: load-carrying capacity is adjustable; Elasticity modulus is with load variations; Load variations elbow, natural frequency are almost constant; Natural frequency is lower.These characteristics have determined air suspension to have the following advantages: (1) takes more comfortable safety; (2) improve the riding comfort of vehicle; (3) service life of prolongation tire and brake plate; (4) bodywork height is constant during load variations; (5) reduce the maintenance cost on electric, air-conditioning, exhaust system, vehicle bridge, vehicle body and chassis; (6) minimizing is protected the road surface to the impact of road, reduces the service expenditure of express highway; (7) prolong vehicle operation life-span and increase the depreciation value.Therefore along with the universal and improvement of this technology, will inevitably be more widely used in the auto-industry afterwards.
Summary of the invention
The purpose of this utility model is to provide a kind of lift bridge hydro pneumatic suspension device, with the weak point that solves original vehicle suspension and meet the need of market.
Lift bridge air suspension of the present utility model, comprise air bag, carriage, single longitudenal arm, crossbeam, lifting capsule, lever arm, lifting arm and shock absorber, it is characterized in that: air bag is separately positioned on the vehicle bridge both sides, the top of air bag is fixed on the vehicle frame, the bottom is fixed on the vehicle bridge with single longitudenal arm by carriage, and the single longitudenal arm other end that bears longitudinal force is connected with crossbeam.
Further, promote the capsule lower end and be fixed on the crossbeam, the lever arm of lifting capsule both sides is connected with the lifting arm on being fixed on vehicle bridge, and an end of shock absorber is fixed on the vehicle bridge, and the other end is connected with vehicle frame.
The utility model can be regulated the allocation proportion that inflation pressure in the air bag guarantees drive axle and the desirable stand under load of lift bridge by pneumatic system, under fully laden, guarantee effectively bearing load of lift bridge, thereby improve vehicle ' ride comfort and crossing ability, improve road surface stand under load situation, improve vehicle life span.
Description of drawings
Fig. 1 is a lift bridge air suspension scheme drawing.
Among the figure: the 1-vehicle bridge, the 2-air bag, 3-promotes capsule, 4-crossbeam, 5-single longitudenal arm, 6-lever arm, 7-lifting arm, 8-shock absorber, 9-carriage.
The specific embodiment
As shown in Figure 1, in the vehicle bridge both sides air bag 2 is set respectively, air bag 2 tops are fixed on the vehicle frame, and the bottom is fixed on the vehicle bridge 1 with single longitudenal arm 5 by carriage 9, and single longitudenal arm 5 other ends that bear longitudinal force are connected with crossbeam 4.Promote capsule 3 lower ends and be fixed on the crossbeam 4, the lever arm 6 of lifting capsule 3 both sides is connected with the lifting arm 7 on being fixed on vehicle bridge 1, and promoting capsule 3 when needing can mention lifting arm 7, thereby drive vehicle bridge 1 and wheel are liftoff.One end of shock absorber 8 is fixed on the vehicle bridge 1, and the other end is connected with vehicle frame, when vehicle is subjected to from ground-surface arbitrary excitation, and the shock absorber extraneous vibrational energy of can decaying rapidly, thus guarantee that with air bag 2 vehicle has good riding comfort.
Travel when causing other vehicle bridge to surpass rated load when vehicle is fully loaded, air compressor is inflated to air bag 2 by the control cock group, this moment, lift bridge landed, inflation pressure in the air bag 2 increases with the increase of load, satisfy the variation relation of the equation of gas state, thereby alleviate the load that other vehicle bridge is born, effectively improve the service life of tire.
When vehicle when zero load or underloading are travelled, suspension can bleed off the gas in the air bag 2 by the control cock group, air compressor inflation in promoting capsule 3 simultaneously, and lifting arm 7 is mentioned by the lever arm 6 of vehicle bridge both sides, and then drive vehicle bridge and wheel liftoff, thereby reach the purpose that reduces wear on tyres and save oil consumption.
Though embodiment of the present utility model has been described with reference to the drawings above, it will be understood by those skilled in the art that under the situation that does not break away from the utility model scope and spirit, can make various modifications and variations to the utility model.Therefore, should be appreciated that the above embodiments are not restrictions, but the casehistory of various aspects.
