Abstract
The utility model relates to a semi-trailer walking mechanism with an air floating bridge, and aims to overcome defects and provide the new technical scheme that the walking mechanism can prolong the service life of vehicles, reduce curb weight of the vehicles, lessen the damage to road surface by the vehicles, save fuel oil, and reduce tire loss. The walking mechanism in the illustration comprises a vehicle frame, a floating bridge suspension unit and two suspension units for steel springs; and a lifting suspension unit is formed by a lifting guiding plate (1), a lateral aerocyst (2), a bracket (3), an air aerocyst guiding plate (4), an air aerocyst supporting plate spring (5), a vibrating absorber (6), an axletree (7), a supporting plate (8) and an air aerocyst (9).
Description
Technical field
The utility model relates to a kind of band superimposed trailer traveling gear, particularly a kind of superimposed trailer traveling gear that has the air flotation bridge
Background technology
Along with expanding economy, air suspension coordinates to be widely used in manned vehicle and goods carrying vehicle and truck cab, but be applied to superimposed trailer, especially for the dangerous chemical tank truck, more embodied its preceence, particularly administer overload in national relevant laws and regulations, when limiting three semi-mounted total masss≤4Ot, the infringement that is applied in lightweight, stability, anti-rollover property, reduces wear on tyres and road pavement of hovering system has more shown its high performance.
The highway of China is repaiied longer and longer, is repaiied better and better, but the difficult paces of catching up with highway construction of the load carrying vehicle that on highway, runs.The level of shipping instrument and high grade highway development demand are far from suitable, and there is huge spread in developed countries such as conveying efficiency and America and Europe.Be embodied in low-speed heave-load, backward, the transport vehicle unreasonable structure of transportation mode.In the U.S., during highway freight equipment constituted, special-purpose goods traffic equipment had almost reached 90%, and its main force is exactly train-type vehicle or superimposed trailer, from the developing history and the development in future trend of U.S.'s freight industry, superimposed trailer will be the main transportation means of highway in China shipping.
In the Eleventh Five-Year Plan that country has finalized a text, " two high " special vehicle will be as the emphasis of encourage growth from now on.Who can at first implement high added value, hightech " two high " special vehicle, just will be the leader in special vehicle market.Report Heze, Shandong overpass is because overload is pressed down recently, country attaches great importance to the overload thing at present, overload causes road damage, the vehicle lost of life, safety to be on the hazard, it also is one of effective means of control overload that vehicle is equipped with air suspension, applying in enormous quantities in the near future on transport vehicles such as truck and trailer.Because pot type dangerization product transport trolley do not allow medium to load in mixture, thus such vehicle to have one way fully loaded, and characteristics that return must zero load.
The utility model content
The purpose of this utility model with overcome above-mentioned weakness, a kind of new technical scheme is provided, it can improve vehicle life span, reduce the curb mass of vehicle, alleviate the vehicle road pavement damage, save fuel oil, reduce tire wear.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: described a kind of superimposed trailer traveling gear that has the air flotation bridge is to be made of vehicle frame and a floating axle suspension unit and two BF unit; Described floating axle suspension unit is made up of lifting guide plate, side direction capsule, support, air bag guide plate, air bag support leaf spring, shock absorber, axletree, stay bearing plate, air bag; Its connecting relation is: support one client link is at the downside of vehicle frame, and the other end connects the air bag guide plate and air bag supports leaf spring; The other end that air bag guide plate and air bag support leaf spring connects axletree; The one client link axletree other end of stay bearing plate connects the lower end of air bag, and the upper end of air bag is bound up on the downside of vehicle frame; The middle part of support also is connected with shock absorber, and the other end of shock absorber connects axletree; One end of side airbag also is bound up on the downside of carriage frame, and the other end of side airbag connects an end that promotes guide plate, and after the lifting guide plate was done fulcrum by the lower end of support, the other end connect axletree; Described floating BF unit is made up of axletree, flat spring bracket, leaf spring; Its connecting relation is: the leaf spring two ends connect with a silk respectively and are connected and flat spring bracket with one, leaf spring middle part axle tree.
Rise bridge in the stroke of semitrailer vehicles zero load, primary shaft is raise makes tire liftoff to not hindering through performance, reduces the purpose that this arbor wheel tire weares and teares and saves the return oil consumption thereby reach.Under the prerequisite that keeps former car smooth-ride, make capacity reach optimum regime.Measuring and calculating return in border adopts lift bridge can save the 5-8% oil consumption, the cost of the recoverable repacking lift bridge of expense that 10000Km left and right sides stroke is saved factually.And the aerodynamic force lift bridge is the effect that utilizes side airbag on the basis of air suspension, can utilize source of the gas that axletree is promoted easily and sets back, and have the characteristics of simple in structure, light self-weight, handled easily.On complete vehicle quality, use floating axle can alleviate the weight of vehicle.
