Description
Affiliated field:
The utility model belongs to a kind of special trailer class that is used to transport particular cargo, and it is particularly related to a kind of low chassis body structure that is used for the special trailer of transport vehicle.
Background technology:
At present on Chinese commodity car transportation market, generally the transportation means of Cai Yonging mostly is the vehicular transport trailer, though once also can load and transport many vehicles in the transportation, but in the actual shipment operation, find also to exist following problem: 1. the body structure of vehicular transport trailer mostly is the fall crossbeam type body structure at present, and loading table top and ground distance are excessive.Cause defines the height of trailer in the state compulsory standard GB1589-2004 " on-road vehicle contour dimension, axle load and quality limit value " that the up-to-date promulgation of State Administration for Quality Supervision and Inspection and Quarantine is carried out threshold limit value is 4000mm.Add that the general vehicle top all is provided with ceiling, further reduce in the last space of vehicle interior, and the too high loading table top of fall crossbeam type body structure, it is littler just to make that car body in-to-in free space becomes, and causes the commodity number of vehicles limited (as: three railway carriage or compartment Xiali generally can be loaded and transported 6) of shipment in once transporting.Delelivered payload capability is poor, and quantity to be loaded is few, and the transportation kind is few, and conveying efficiency is low, the traffic cost height.2. adopt fall crossbeam type body structure vehicular transport trailer, lower floor's loading table top and ground distance are big, so charge and discharge operations inconvenience, and be accidents caused easily, produces dangerous; 3. high body structure (fall crossbeam type body structure) makes the vehicle's center of gravity height, the riding stability variation; 4. the body structure raw materials consumption amount of fall crossbeam type is big, curb mass is big, manufacturing cost is high, and fuel economy is poor.5. the body structure of fall crossbeam type produce assembly technology loaded down with trivial details, consuming time many, work capacity is big, production efficiency is low.6. the gas circuit brake system of general vehicle transportation trailer adopts independently air receiver to store pressurized air.Independently air receiver takes up space greatly, and the design arrangement difficulty also can influence the inner free space of car body, influences the delelivered payload capability of vehicle.7. the suspension of general vehicle transportation trailer is used straight shape vehicle bridge, limited by its shape, can't reduce lower floor's loading table surface height.8. at present many, the volume of the used leaf of spring number of the suspension of vehicular transport trailer greatly, take up room many; And front frame, medium-height trestle and after poppet volume be big, it is big to take up room.
Goal of the invention:
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and a kind of Trailer Low Chassis Vehicle Body Structure is provided, and this structure makes vehicle compact overall structure, inside can utilize the space big; Improve vehicle delelivered payload capability, make things convenient for car loading operation; The good stability of vehicle '; Production technology is simple, production efficiency is high; But and conservation, cost-cutting has alleviated complete vehicle curb weight simultaneously, has improved fuel economy.
The technical solution of the utility model is: a kind of Trailer Low Chassis Vehicle Body Structure is characterized in that: the frame-type vehicle body of being made of pin-connected panel left side stand, right side stand, upper strata loading platen and lower floor's loading platen; Lower floor's loading platen connects left side stand and right side stand; Lower floor's loading platen comprises front cross rail, center member and after cross member, and its bottom is connected with suspension; Vehicle bridge adopts the spill vehicle bridge, and wheel hub and axletree are eccentric structure; Above-mentioned suspension is made up of front spring spring, rear leaf spring, front frame, medium-height trestle, equalizing bar, after poppet and secure component, and front frame is connected with front cross rail, and medium-height trestle is connected with center member, and after poppet is connected with after cross member, and medium-height trestle connects equalizing bar; The two ends of front spring spring are connected with equalizing bar with front frame respectively, and the two ends of rear leaf spring are connected with after poppet with equalizing bar respectively; Vehicle bridge below before the front spring spring is fixedly connected on, rear leaf spring are fixedly connected on vehicle bridge below, back.
Above-mentioned front cross rail, center member and after cross member are the fully enclosed hollow structure.
Above-mentioned front spring spring and rear leaf spring adopt few chip variable-section steel sheet spring.
Above-mentioned front spring spring and rear leaf spring are respectively by " U " shape bolt and pressing plate fixed thereon and preceding vehicle bridge, back axle attachment.
The utility model has the advantages that: 1, adopt Trailer Low Chassis Vehicle Body Structure, reduced the height of lower floor's loading platen, make the free space of vehicle interior increase.Delelivered payload capability is strong, and cargo-carring commodity number of vehicles is many in a hauling operation.It is wide in variety to load the commodity vehicle, and applicability is strong.The conveying efficiency height has reduced traffic cost.2, adopt Trailer Low Chassis Vehicle Body Structure, lower floor's loading platen and ground distance are little, so charge and discharge operations is convenient, safe and reliable.3, adopt Trailer Low Chassis Vehicle Body Structure, the vehicle compact overall structure, center of gravity is low, and riding stability is good.4, adopt Trailer Low Chassis Vehicle Body Structure, save raw MAT'L, low cost of manufacture reduces curb mass, has improved fuel economy.5, adopt Trailer Low Chassis Vehicle Body Structure, production technology is simple, the production efficiency height.6, front cross rail, center member, after cross member are the fully enclosed hollow structure, utilize its air receiver as the trailer Pneumatic braking system to store pressurized air.Save independently air receiver, do not taken limited inner space.7, Trailer Low Chassis Vehicle Body Structure adopts the spill vehicle bridge, and wheel hub and axletree are eccentric structure.Reached the purpose that reduces lower floor's loading platform plate height.8, the suspension of Trailer Low Chassis Vehicle Body Structure is reasonable in design, and load-carrying capacity is strong, and volume is little, occupies little space.
