Accompanying drawing explanation
Fig. 1 is the schematic diagram of an embodiment of dual-rear axle commercial car;
Fig. 2 is the front elevation that jackshaft promotes an embodiment of airsuspension system;
Fig. 3 is the birds-eye view that jackshaft promotes an embodiment of airsuspension system.
Detailed description of the invention
Now by reference to the accompanying drawings 1,2,3 and specific embodiment this case is further described.
As shown in Figure 1, bridge vehicle after two for commercial vehicle/comm..vehicle, the weight of vehicle vehicle in operational process is by propons, jackshaft (lift bridge---do not provide propulsive effort) and back axle (drive axle) shared.As Fig. 2, guide arm support is connected with vehicle frame bolt, relatively fixing; Guide arm and guide arm support are bolted at the grasswort place of guide arm, and guide arm can rotate around this bolt; It is urgent, relatively fixing that guide arm and lift bridge pass through U-bolt; Carrying air bag top is fixedly connected with vehicle frame, and bottom is fixedly connected with guide arm end, can carry out inflation/deflation motion; Promote air bag lower bracket to be connected by bolt with guide arm support, relatively fixing; Promote air bag upper bracket and lift bridge welding, relatively fixing; Promote air bag top to be connected with lifting air bag upper bracket, bottom is connected with lifting air bag lower bracket, can carry out inflation/deflation motion; On shock absorber, grasswort is connected with vehicle frame, and bottom is connected with lift bridge, can produce fore and aft motion.
Promoting air bag is bellows airbag structure, and described carrying air bag is membrane type airbag structure.Guide arm adopts two-piece type structure, and carrying air bag is arranged in wherein a slice of guide arm.Carrying air bag connects levelling valve, and described guide arm support adopts v-shaped structure.Lifting air bag center is that lift bridge center is to 1/2 of guide arm grasswort distance to the distance of guide arm grasswort.The flexible stroke of shock absorber is 1.2 times of the upper and lower stroke of lift bridge.The flexible stroke of carrying air bag is 1.56 times of the upper and lower stroke of lift bridge.Above data are decision design, and concrete ratio can be installed by parameter situation specific designs such as vehicle frame ratio, vehicles.
A kind of commercial vehicle/comm..vehicle, is equipped with above-mentioned jackshaft and promotes airsuspension system, the direction being front with garage direction, and the jackshaft be equipped with described in a group at left and right side jackshaft promotes airsuspension system, and two groups of suspension systems are symmetrical centered by vehicle frame line of centers.
Vehicle is under full load conditions, during normal bearing goods state, control to carry out inflation/deflation adjustment suspension height to carrying air bag by levelling valve, allow lifting air bag be in deflation status always, namely communicate with air, by carrying air bag and guide arm common support tare, carry out inflation/deflation by carrying air bag and regulate bodywork height, vehicle is under no-load condition, because tare is very light, the power passing to two back axle wheel is less, now carry air bag deflation (carrying effect is not provided), namely communicate with air, to lifting airbag aeration until certain pressure, by promoting the increase of air bag height, air bag upper bracket upwards jack-up will be promoted, jack-up is rotated around guide arm grasswort place bolt by middle lift bridge, vehicle is by back axle bearing vehicle body weight, promote the weight of air bag carrying lift bridge, and then the weight of vehicle is converted into propons and back axle shared completely, jackshaft does not provide carrying effect, back axle so just can be made to carry larger weight to obtain enough propulsive efforts, reduce the wearing and tearing of jackshaft tire and the rolling resistance to ground simultaneously, reduce oil consumption, for user increases economic benefit.
Finally should be noted that: above embodiment is only in order to illustrate that the technical scheme of this case is not intended to limit; Although be described in detail this case with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to the detailed description of the invention of this case or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of this case technical scheme, it all should be encompassed in the middle of the technical scheme scope of this case request protection.
