At present, market mainstream car load four gasbags hovering structure rear axle part by forging bracket, double bolloon, 2-4 prop up bumper, stabilizer rod system and height control system and form.There is following defect in this system: bracket, from great, causes unsprung weight to increase; Air bag and stabilizer rod system are arranged on bracket more, increase bracket load, and stress is concentrated, and causes component life to reduce; Meanwhile, because air bag, bumper and stabilizer rod system are away from drive axle, manipulation stability is caused to decline; Easily cause chassis to be shifted to be out of shape.
Utility model content
For overcoming above-mentioned technological deficiency, the utility model provides a kind of compact conformation, connection and reasonable arrangement and is easy to assembling, eliminates the rear airsuspension system of passenger vehicle of traditional bracket, reduce unsprung weight, system lightweight is obvious, cost squeeze, suspension reasonable stress, improves car load manipulation stability.
The technical solution of the utility model is:
A kind of passenger vehicle air suspension after Novel lightweight double bolloon, comprise bridge upper cover plate, bridge upper cover plate is fastenedly connected by U-bolt and driving axle housing and bridge bottom plate, V-type bearing on driving axle housing and upper thrust rod hinged, upper thrust rod other end connecting vehicle frame, the hinged lower thrust rod of bridge bottom plate lower seat, lower thrust rod other end connecting vehicle frame, driving axle housing and bridge bottom plate are weldingly connected, bridge bottom plate is provided with mounting hole, and bridge upper cover plate is provided with two erection support holes and is connected with air bag assembly, ECAS height control system respectively.
Groove inclined-plane in the middle part of described bridge bottom plate is corresponding with bridge upper cover plate inclined-plane, the elevation angle after accurate Locating driver bridge.
Described bridge bottom plate is arranged a mounting hole, stabilizer rod suspension rod and bumper are arranged in this mounting hole.
Described bridge bottom plate is arranged two mounting holes, respectively stabilizer rod suspension rod and bumper are installed.
Described stabilizer rod suspension rod is connected with stabilizer rod, and stabilizer rod is connected by bush Assembly with vehicle frame.
The utility model has two kinds of installing conditions: " integral type " installing condition, and stabilizer rod suspension rod and shock absorber are arranged in a mounting hole of bridge bottom plate, and namely stabilizer rod suspension rod is connected with shock absorber and uses an installation site; " stand alone type " installing condition, bridge bottom plate is provided with two mounting hole site, is connected respectively with stabilizer rod suspension rod, bumper, and above two states is selected flexibly with regard to actual conditions.
Outstanding advantages of the present invention is:
1, the present invention compares conventional bracket structure, adopts bridge bottom plate to replace conventional bracket, greatly reduces unsprung weight, compression productive costs, promote car load manipulation stability and reduce the use cost of car load, due to the minimizing of parts, also improve the efficiency of assembling of car load factory.
2, the bridge bottom plate intermediate groove portion in the present invention is provided with inclined-plane, and corresponding with the inclined-plane of bridge upper cover plate, two parts are fastenedly connected by U-bolt and axle housing, ensures drive axle elevation accuracy.
3, in the present invention, shock absorber, stabilizer rod system are connected directly between on bridge bottom plate, greatly simplify suspension frame structure, improve the integrated level of suspension system, save vehicle body boot compartment space, decrease the use amount of parts, cost squeeze simultaneously, facilitate after-sales service.
4, in the present invention, air bag is directly installed on bridge upper cover plate, while designs simplification, the horizontal span of augmented airbag, air bag setting height(from bottom) promotes, and is conducive to controlling the inclination in vehicle travel process, strengthen roll rate, lifting vehicle riding stability, is conducive to the safe driving of vehicle.
5, in the present invention, the lower fulcrum connection location of bumper reduces, and improves the riding stability of car load, enhances the safety that vehicle travels; Bumper and balloon mounting location, closer to axle housing, more effectively slow down impact-attenuating vibration, ensure that the traveling comfort that passenger takes.
6, in the present invention, bridge upper cover plate, bridge bottom plate all adopt the casting of quality matetrial essence to form, and fully ensure that the safety of component structural performance, extend the service life of suspension system, reduce maintenance cost.
7, in the present invention, ECAS height control system is arranged on bridge upper cover plate, installation site is more near wheel, tire height change of jolting can effectively be caught by levelling valve, regulate air bag height and air bag rigidity in time by ECAS height control system, ensure the manipulation stability of the traveling comfort of passenger, safety and chaufeur.

Detailed description of the invention
A kind of passenger vehicle air suspension after Novel lightweight double bolloon, comprise bridge upper cover plate 11, bridge upper cover plate 11 is fastenedly connected by U-bolt 9 and driving axle housing 18 and bridge bottom plate 8, groove inclined-plane 15 in the middle part of bridge bottom plate 8 is corresponding with bridge upper cover plate inclined-plane 16, the elevation angle 17 after accurate Locating driver bridge, V-type bearing 14 on driving axle housing 18 is hinged with upper thrust rod 1, upper thrust rod 1 other end connecting vehicle frame, the hinged lower thrust rod 10 of bridge bottom plate 8 lower seat, lower thrust rod 10 other end connecting vehicle frame, driving axle housing 18 and bridge bottom plate 8 are weldingly connected, bridge bottom plate 8 is provided with mounting hole 13, bridge upper cover plate 11 be provided with two erection support holes respectively with air bag assembly 3, ECAS height control system 2 connects.
Bridge bottom plate 8 divides two states with the connection mode of shock absorber 4 and stabilizer rod system: as depicted in figs. 1 and 2, for " integral type " installing condition, bridge bottom plate 8 is arranged a mounting hole 13, stabilizer rod suspension rod 7 and shock absorber 4 are arranged in a mounting hole of bridge bottom plate 8, and namely stabilizer rod suspension rod 7 is connected with shock absorber 4 and uses an installation site; " stand alone type " installing condition shown in Fig. 3 and Fig. 4, bridge bottom plate 8 arranges two mounting hole site, is connected respectively with stabilizer rod suspension rod 12, bumper 4.
In vehicle travel process, the load of vertical direction is carried by two air bags, stressedly in horizontal surface is controlled by two upper thrust rods and two lower thrust rods; When vehicle travels on rough road surface, whole suspension system is with the junction (propelling rod front end) of four propelling rods and vehicle frame end for the center of circle, and corresponding propelling rod is long is radius, does circular motion in perpendicular; When vehicle travels recess, propelling rod front end keeps horizontal stationary, wheel and suspension system are sunk, circular motion is done downwards in propelling rod rear end, air bag height increases, the effect of ECAS height control system, airbag aeration, planar horizontal position on air bag is remained unchanged, and corresponding bodywork height remains unchanged.When vehicle travels protrusion road conditions, Suspension movement is just in time contrary.
